With the development of smart phones, the technology is very mature and the price is not expensive. Therefore, almost everyone has two mobile phones now, but the charging time of smart phones is sometimes long and sometimes short. What is the reason?
There are two ways for the charger to charge the phone:cradle chargeanddirect charge.
The cradle charge is to remove the battery and charge it on the charger, and the corresponding is the direct charge, that is, the charger is directly connected to the mobile phone to charge.
USB charging refers to the use of electrical equipment with a USB interface to charge mobile phones, and currently refers to PCs and laptops. Usually, USB charging takes much longer than charger charging. In order to explain the difference between USB charging and DC charging, we must first understand the charging principle of lithium batteries.
The charging method of lithium battery is limited voltage and constant current, which generally goes through three charging stages:
pre-charge, the voltage is less than 3V at this time;
Constant current charging. After the voltage reaches 3V, it enters the fast charging stage. At this time, the current is relatively large, and the constant current charging continues until the voltage rises to 4.2V;
Constant voltage charging, when the voltage rises to 4.2V, it is changed to small current charging, while the voltage of 4.2V remains unchanged. Usually, the current at this time is 1/10 of the constant current stage.
The cradle charging and direct charging methods will respectively cause a certain impact to the lithium battery and the mobile phone, and will cause a certain degree of damage in the long run. The USB output current is smaller than the above two, which is why the USB charging time is longer than the two. This small current is manifested in the constant current and constant voltage stages. The purpose of constant voltage charging is to supplement the capacity loss of lithium-ion batteries due to self-discharge after being fully charged.
At present, the USB output voltage of the computer is 5V, the output current is 500mA, and the charging current of the charger is 1000mA. Because the USB output current is small, its current in the constant voltage stage is even smaller.
Therefore, charging with USB feels longer, of which, the more important is the longer time spent in the constant voltage phase. If you can’t wait and end the process of charging the phone with USB as soon as possible, because there is still a part of the supplementary power that has not been charged, it seems that it is not fully charged. This is actually a current problem rather than leakage and other problems that consumers are worried about.
However, the problem of “not fully charged” has little effect. Even if there is no constant voltage charging process,the battery at this time has at least 90% capacity.For lithium batteries, as long as they are not overcharged and overdischarged, they can be charged at any time. , which is the difference between it and NiMH batteries.
Lithium-ion batteries have firmly woven themselves into the fabric of our daily lives. However, like every piece of technology, they’re not infallible. Ensuring their optimal health and troubleshooting issues like charging problems is crucial for the longevity of our devices and our peace of mind.
What is a Lithium Ion Battery?
Lithium-ion batteries are marvels of modern technology. Comprising of an anode, a cathode, and an electrolyte, these batteries derive their power from the motion of lithium ions between the anode and cathode. When discharging, the ions travel from the anode to the cathode, producing the electrical charge. The reverse takes place during charging. The widespread adoption of lithium-ion batteries is attributed to their myriad advantages. Firstly, their high energy density is commendable. They can pack a lot of power in a relatively small space, making them ideal for devices where size and weight matter. Furthermore, they are lightweight, which is a boon for portable devices. Also, these batteries aren’t plagued by the ‘memory effect’ that older battery technologies suffered from, meaning they don’t need to be completely discharged before recharging.
How Many Times Can You Recharge Lithium-Ion Batteries?
Lithium-ion batteries showcase a vast spectrum in terms of rechargeability, greatly influenced by their chemical composition. To delineate, a conventional lithium-ion rechargeable battery offers a cycle life within the bracket of 300 to 500 cycles. Contrastingly, Lithium Iron Phosphate (LiFePO4) batteries are a paragon of resilience, boasting an extensive cycle life that can reach up to 2000 cycles. Their enhanced cycle life not only underscores a promising sustainability quotient but also positions them as a preferred choice for heavy-duty applications. A ‘cycle life’ epitomizes a battery’s vitality, defined as one full charge followed by a discharge. This concept is analogous to the mileage of running shoes, governed by not only the intrinsic quality but also the usage patterns. However, cycle life isn’t a static parameter; it undergoes a gradual decline due to several influencing factors, akin to wear and tear experienced by running shoes over time.
Temperature: Quantitative Insight: Batteries operated within the optimal temperature range of 15°C to 25°C demonstrate a slower degradation rate, potentially enhancing the cycle life by up to 20% compared to batteries consistently exposed to temperatures above 45°C. Charging Rate: Comparative Data: Studies indicate that batteries charged at a slower rate (0.5C) can outlast those charged at a higher rate (1C or more), extending cycle life by approximately 20-30%. Depth of Discharge (DoD): Quantitative Analysis: A battery undergoing a DoD of 20% before recharging can exhibit a cycle life extending up to 3750-4700 cycles, starkly superior to a battery experiencing a 100% DoD, whose cycle life might be confined to 300-500 cycles.
Therefore, embracing a meticulous approach to maintaining optimal conditions can pave the way for lithium-ion batteries to reach, or possibly exceed, their expected cycle life. Drawing parallels between various influencing factors and utilizing quantitative insights can aid professionals in nurturing a holistic understanding of lithium-ion battery cycle life. As we navigate through the nuances, it becomes imperative to approach battery usage with a nuanced perspective, acknowledging the variables that dictate the longevity and efficacy of lithium-ion batteries.
Why Is My Lithium Battery Not Charging?
It’s a sinking feeling when you plug in your electronic devices, eagerly waiting for that charging icon, and it’s nowhere to be seen. But what’s behind this? Let’s explore some of the culprits that might be keeping your lithium battery from charging.
The Growing Challenge of Internal Resistance
Every battery has what’s known as internal resistance. It’s a natural barrier to the flow of current within the battery. As the battery ages and goes through more charge and discharge cycles, this resistance tends to increase. When it reaches a certain threshold, it can significantly hamper the battery’s ability to charge. Imagine trying to run in waist-deep water; the resistance slows you down, much like increased internal resistance slows down charging.
The Temperamental Nature of Temperature
Batteries, much like us, have their comfort zones. When they’re exposed to extreme cold, the chemical reactions inside them slow down, making charging a challenge. On the flip side, extreme heat can cause the battery’s internal components to degrade faster, also affecting its charging capability. It’s always a good idea to keep your devices away from extreme temperature conditions for their overall health.
The Perils of Over-Discharge
Over-discharging happens when a battery’s charge dwindles down to an extremely low level, sometimes almost to zero. This is especially detrimental to lithium-ion batteries. When they’re over-discharged, the battery’s voltage plunges so low that the built-in battery management system (BMS) may think the battery is defective or dead. To prevent potential safety risks, the BMS might stop the battery from charging as a precautionary step.
What’s more, over-discharge can cause the battery cells to reverse in polarity. In layman’s terms, instead of the cells operating in sync, they begin working against each other. This not only stops the battery from charging but can also make it dangerous to use. If you think your battery might be over-discharged, handling the situation carefully is critical. Sometimes, specialized chargers might bring such a dead battery back to life, but consulting a professional is always the safest route.
The Inevitable Wear of Battery Age
Just like any other component, batteries have a lifespan. As they age, their capacity to hold a charge diminishes. If you’ve been using your battery for a long time and it’s not charging, it might simply be reaching the end of its life. Regularly monitoring your battery’s health can give you a heads-up when it’s time for a replacement.
The Often Overlooked Charger Issues
Sometimes, the battery is perfectly fine, but the charger or charging cable is the culprit. Faulty chargers or damaged cables can prevent the necessary current from reaching the battery. It’s always a good idea to test with a different charger or cable to rule out this possibility.
In conclusion, if you’re trying to fix a lithium-ion battery that won’t charge, understanding these potential issues can guide you in the right direction. Whether it’s addressing over-discharge, checking your charger, or simply acknowledging that it might be time for a new battery, being informed is half the battle.
How to Fix a Lithium Ion Battery That Won’t Charge?
We’ve all been there: eagerly waiting for that charging icon to appear, only to be met with disappointment. Before you consider your battery a lost cause, let’s explore some potential remedies.
Check Charger and Cable
When diagnosing lithium battery charging issues, it’s imperative to consider accessory functionality, specifically focusing on chargers and cables, often overlooked components. For instance, a minor misalignment in cable wiring or a flaw in the charger’s internal mechanism could lead to charging discrepancies. Verify the integrity of your charger and cable by examining their conditions and conducting compatibility tests with other devices, ensuring they meet the standard voltage requirements and aren’t inducing any voltage drops or interruptions. Reliable data indicates that around 15% of charging issues stem from faulty accessories rather than the battery unit itself. Always opt for accessories that are certified and comply with quality and safety standards, ensuring a stable power supply and mitigating risks of malfunction. These subtle yet critical checks serve as preliminary steps in pinpointing and resolving charging abnormalities, providing a foundation for more in-depth analysis if needed.
Clean the Battery Contacts
Battery contacts play a pivotal role, serving as conduits for efficient energy transfer. Yet, with time and exposure, these contacts may be compromised by dirt or corrosion, undermining their efficacy. Research indicates that approximately 10% of lithium battery charging issues can be attributed to obstructed contacts. To maintain peak performance, it’s paramount to periodically inspect these contacts. Subtle discoloration or debris buildup might indicate the onset of inefficiencies. Employ a soft cloth or a specialized eraser for gentle cleaning. Always prioritize safety: ensure the device is powered off, and where feasible, detach the battery during the cleaning process. Recognizing and addressing contact degradation not only prolongs battery lifespan but also ensures consistent charging and power output, consolidating the foundation for optimal battery health and performance.
Reduce Battery Self-discharge
Extended inactivity of lithium batteries can result in what is termed “deep discharge,” a state where the battery’s voltage drops to an exceedingly low level. Such conditions, over prolonged periods, can jeopardize the battery’s internal chemistry and structure. A recent study indicates that batteries kept at a near-zero charge level for over a month might see a degradation rate almost twice as fast as those maintained at a 50% charge level. To revive a deep-discharged battery, gently warm it within the safe threshold of 40°C, allowing the internal electrolyte’s mobility to improve, then proceed with charging. However, as a preventive measure, professionals advise retaining batteries within a 20%-80% charge range during storage periods. Such practices not only prevent extreme discharge states but also contribute to prolonging battery life, optimizing overall performance and safety.
Consider Environmental Factors
Temperature significantly influences lithium battery performance and charging efficiency. A deviation from the optimal range, be it cold below 0°C or heat exceeding 40°C, hampers charging capabilities. Research has shown that batteries exposed to temperatures above 60°C can experience a drop in efficiency by up to 40%. Conversely, those subjected to sub-zero conditions might exhibit diminished charge uptake. For optimal performance, it’s crucial to store and charge batteries in controlled environments between 20°C to 25°C. Understanding and respecting these temperature bounds not only ensures consistent charging but also extends the overall battery lifespan, maximizing the return on investment.
Consider Battery Lifespan
Every lithium-ion battery possesses a finite life, quantified in terms of charge cycles. Typically, a single cycle represents one full charge and discharge. As per industry data, most lithium-ion batteries maintain optimal performance up to 300 to 500 cycles, post which there’s a noticeable decline in capacity, often dropping to 80% or less of their original capacity. For instance, a battery that initially provided 10 hours of usage might dwindle to just 8 hours after surpassing its cycle threshold. It’s essential to recognize these signs of aging. If a battery consistently underperforms despite proper maintenance, it’s likely nearing the end of its effective lifespan. In such scenarios, the most pragmatic solution is replacement.Understanding and tracking charge cycles not only aids in anticipating battery replacements but also ensures devices operate at peak efficiency.
Maximizing the Lifespan of Your Lithium-Ion Battery
We’ve all been there: the dread of watching our device’s battery life diminish faster than we’d like. But with a little knowledge and care, you can extend the life of your lithium-ion battery, ensuring it serves you well for years to come.
Mindful Charging: While it’s tempting to charge your battery to 100% and drain it to the last drop, it’s not the best practice. Lithium-ion batteries prefer to be kept at a charge level between 20% and 80%. Consistently charging your battery to its full capacity or letting it discharge entirely can stress the battery, reducing its overall lifespan Update Regularly: It’s not just the hardware that affects your battery life; software plays a role too. Regular software updates often come with optimizations that can improve battery efficiency. So, next time you see that update notification, don’t ignore it. Limit Fast Charging: While fast charging is incredibly convenient, especially when you’re in a hurry, it’s not something you should use all the time. The increased current can generate more heat, which, as we’ve established, isn’t great for the battery. Use fast charging sparingly, and your battery will thank you. Store Smartly: If you’re not going to use a device or battery for an extended period, store it properly. Ideally, the battery should be at around 50% charge. Keep it in a cool, dry place away from direct sunlight. Regular Check-ups: Every once in a while, it’s a good idea to check your battery’s health. Some devices have built-in diagnostics, while others might require third-party apps. Being aware of your battery’s health can help you take timely action,whether it’s changing usage habits or considering a replacement.
In the end, while lithium-ion batteries might seem like mysterious little boxes, understanding their needs can go a long way in ensuring they last longer. After all, a little care can make a world of difference.
Laptop batteries power portable devices but can degrade over time, impacting your laptop’s performance. Understanding how batteries work and what affects their lifespan, diagnosing common issues, and maintaining them can extend their life. This article will guide you on how to repair a laptop battery — optimizing battery performance, exploring upgrade options, and deciding whether to replace or upgrade your battery.
Understanding your battery is key.
Most modern laptops are powered by lithium-ion batteries, which are the industry standard due to their efficiency and reliability. However, these batteries come with a finite number of charge cycles. A charge cycle is defined as a full discharge of the battery from 0% to 100% and then back to 0% again. It’s important to note that partial discharges also contribute to these cycles. For example, using 50% of your battery one day and recharging it, then using 50% the next day, counts as one full charge cycle.
Each charge cycle gradually diminishes the battery’s capacity to hold a charge. When new, a lithium-ion battery might allow you to work for several hours on a single charge, but after numerous cycles, you may notice that your laptop doesn’t last as long. This is a natural ageing process for the battery, as the chemical reactions within it slowly degrade over time.
Understanding this concept can help you better manage your laptop’s battery life. For instance, avoiding full discharges and instead keeping your battery between 20% and 80% can significantly extend its lifespan. Employing features like Battery Saver mode can reduce the number of cycles your battery undergoes, helping to preserve its capacity.
By taking care of your battery and being mindful of its charge cycles, you can ensure that your laptop remains reliable and efficient for a longer period.

From the beach to the boat, wherever we go to enjoy warmer weather, our phones are usually right along for the fun and keeping them above water can be a challenging task. No matter how much you bought your phone, seeing it get damaged is not a pleasing moment at all – even if it’s just a slight crack on the screen.One of the frustrating situations is when your phone falls into the water – either in the toilet or in a pool of water. You may feel terrified and tense at the same time to the extent of not knowing what to do. In case your device does take a plunge, here are tips for getting water out of your phone that you’ll need to know.
How to get water out of your phone
Here’s what to do if you drop your phone in water or get it wet:
Remove it from the liquid immediately. The longer it stays there, the more liquid will seep into various inlets.
Turn the phone off and leave it off.
Remove the protective case.
If possible, open the back and remove the battery, SIM card, and microSD card (if you have one).
Use a cloth or paper towel to dab your phone dry. Do not rub the phone, as doing so could accidentally push liquid into the phone’s more sensitive parts. If the phone was completely submerged, you might try (very) gently vacuuming around the phone’s creases and openings to suck more water out.
Resist the urge to bake your phone in the sun. Keep it in a cool, dry place.
You’ve probably heard the suggestion to put your phone in rice if it gets wet, but we do not recommend this method. Instead, try silica gel packets, like the ones that often come with new products such as a pair of shoes, as they’ve proven to be much more effective. Fill a plastic zip-top bag with silica gel packets and bury the phone in the bag. Leave your phone in the bag for 24–48 hours.
After you’ve allowed your phone to fully dry, switch it on. If it doesn’t turn on right away, charge it fully and try again.
If your phone turns back on, great! Still, keep an eye on it over the next week or so, as sometimes certain features won’t work the way they used to.
The immediate pros of wireless charging are apparent for all to see. Smartphones and smartwatches can be easily rejuvenated when plopped onto charging pads, eliminating the need for rummaging through messy tables and drawers for cables. As long as there’s a wireless charging pad at your destination, bringing along your device is all you need.
How does wireless charging work?
Tightly-coupled electromagnetic induction
Wireless charging occurs when electricity is transferred from the charging pad to device via a process known as electromagnetic induction, where a magnetic field is produced between the wireless charging transmitter and receiver. Electricity is generated when the generated magnetic field interacts with copper coils in the receiving device, thereby charging the battery.
The most common form of wireless charging today is a sub-category known as tightly-coupled electromagnetic inductive charging, where the transmitting and receiving copper coils must be aligned and within close proximity for effective charging. Any misalignment will significantly slow down charging or cause the process to cease altogether.
Is Wireless Charging Bad For Your Phone?
Heat generated From Wireless Charging
Wireless charging is commonly misunderstood to be harmful for phone batteries due to the heat it generates. While it’s true that electromagnetic induction produces more heat than conventional wired charging, effects from the produced heat can be mitigated with careful management.
Furthermore, phone batteries are typically separated from copper charging coils by a layer of thermal insulation. The result is that smartphone battery temperatures can typically be contained within safe limits under normal circumstances.
Does wireless charging impact battery charge cycles?
Battery charge cycles refer to the number of times a rechargeable battery can undergo complete charging before losing their ability to hold a charge. One charging cycle is completed when a battery goes from being completely charged to completely discharged. Charging a battery from 50% to 100% will therefore only use up half of a battery cycle. Because battery charge cycles are influenced by the number of times they are charged rather than the charging method, wireless charging will not harm a device’s battery.
The only thing that consumers have to worry about is constant charging throughout the day, or charging a device even after it reaches maximum charge carrying capacity. Whenever a battery is charged, energy released will cause lithium ions to move from the graphite layer to the lithium cobalt oxide later. Overcharging can cause damage in the long run by pulling out 100% more lithium ions and messing up the internal battery structure. Most smartphone battery management systems prevent this by blocking current from entering fully charged batteries even while they are connected to a charger.
Does wireless charging pose a safety hazard?
There have been reported instances of wireless chargers being recalled due to safety concerns. Reported risks include fire, electric shock, injuries, or damage to phone and surrounding property. As a result, manufacturers have also warned consumers about sleeping beside charging devices or placing them in poorly ventilated areas, such as beneath a blanket or pillow.
What precautions should be taken during wireless charging?
Safety can be compromised whenever foreign objects such as coins, credit cards, or other metal objects obstruct the space between transmitter and receiver. These foreign objects receive power from the generated magnetic field and dissipate it in the form of heat, which can create damage to both device and user.
For manufacturers and consumers, the most foolproof way to minimize risk is to ensure that their devices comply with recognized charging standards so that the necessary safeguard mechanisms are in place to shut down the charging process before things get out of hand.
3 Tips for a Longer Battery Life
A long-lasting smartphone battery life can improve your overall user experience, minimize device interruptions and prolong your device’s lifespan. Here’s how you can ensure your smartphone’s battery life is efficiently optimized:
Keep Your Battery Level Balanced
At all cost, try to maintain your phone’s battery level between 20% and 80%. This range is considered the optimal battery lifespan zone. It’s advisable not to repeatedly let your phone’s battery drop below 20% as this puts a strain on it. On the contrary, charging your smartphone 100% isn’t a healthy practice either.
Practice Cautious Wireless Charging
If you’re a fan of wireless charging, ensure not to always keep your phone on the charging pad. Just like wired chargers, leaving your phone on a wireless charging pad for extended periods can lead to overcharging and possible battery degradation.
Minimize Fast Charging
hough convenient, fast charging can negatively impact your smartphone battery’s health. The heat generated from fast charging might degrade your battery very quickly. Thus, it’s wise to minimize the use of fast charging and resort to it only when it’s absolutely crucial.
Batteries are an essential component of almost every device. However, it is widely known that it tends to be the first one to lose its power after being used extensively. Even the most reliable devices such as laptops and phones lose their capability to charge at some point because their battery’s life cycle is already used up.
But don’t fret because there are a lot of ways that you can do to prolong the life of your battery, all it takes is proper care and the knowledge on how to maintain them correctly. By doing this, your battery will surely last for a long time.
Here’s what you can do:
Avoid Using The Device In Extreme Temperatures
Most of the devices are made to be portable nowadays, making them convenient to be used wherever you are. But, you have to take note that there are certain limitations when exposing it to extreme temperatures in an extended period of time.
The Ideal temperature zones are 16° to 22° C and it’s crucial not to use it when the temperature is higher than 35° C, due to the fact that it can damage your battery permanently. Also, charging the batteries in a room that exceeded the recommended temperature will disrupt the battery’s performance even further.
Save Your Battery’s Life Cycle
This may be difficult to do especially if you often rely on your device to accomplish your day-to-day tasks. However, if it’s really your goal to prolong the lifespan of your battery, turning it off once a week can help it to perform longer by saving its life cycle.
Normally, a battery can survive up to 500 charge cycles and each cycle lessens its capacity to perform efficiently. If you can’t turn off your device for a day, some devices allow you to change the power settings that will benefit the battery’s life in the long run.
Removing Your Battery When Not In Use
This has been one of the most asked questions by people .Is it really necessary to remove your battery when the device is not in use?
Well, every brand has a different opinion regarding this matter— with Apple telling customers not to take their batteries out and Acer which recommends that you should take it out if you don’t plan to use it for more than a week.
But generally, if you are planning not to use the device for a couple of days or more it is advised to have it charged between 40 to 80 percent and must be stored at room temperature. This way, it will be ready to use again when needed rather than discharging it completely before storing it somewhere else. Never store a fully discharged battery, they should always be charged for maximum longevity.
Only use ultra-fast charging when necessary
Fast charging is convenient, but don’t use it every time you charge your phone. Fast charging puts more stress on the battery than necessary, so battery performance can suffer over time. Opt for a standard “slow” charge more often than not to preserve battery longevity.
Use your phone sparingly while it’s charging
To avoid parasitic load, don’t play games or stream videos while charging your phone. Parasitic load is what happens while a battery is being drained during charging. Parasitic load adds higher voltage stress to the battery, increases heat, and can cause parts of the battery to continually cycle and deteriorate faster than the rest of the cell. While you can take calls or browse the web during a charging session, avoid heavy tasks.
Keep track of your phone’s battery health
Both iPhones and Androids have built-in tools for battery health tracking. You can use these tools to find out more information about your battery’s performance and life span using these tools.
iPhone: Open your Settings and go to Battery > Battery Health.
Samsung Galaxy: Open the Samsung Members app and go to Get Help > Interactive checks (or View tests) > Battery status (or Battery).
Other Androids: Open the Phone app and dial *#*#4636#*#*. When the menu appears, select Battery information (it may be buried in another menu).
You can also try other Android battery health apps, such as CPU-Z, Battery by MacroPinch, and AccuBattery by Digibites.
But You Have To Remember…
Eventually, batteries will lose their power and will hold less charge over time. What makes proper care beneficial is it will enable you to use the battery longer and will save you time and money from replacing it earlier than expected.
YOU MIGHT BE in the habit of replacing your smartphone every couple of years, but most phones can last a lot longer than that. Like your car, they might just need a new part every now and then, and the best repair you can do on your phone to make it last longer is a battery replacement. But most batteries aren’t user-replaceable. So how do you actually get one?
Unfortunately, user-replaceable batteries are becoming increasingly rare, and most smartphone manufacturers don’t go too far out of their way to let you know that you can get a battery replacement at all. In fact, when Apple briefly lowered the cost of iPhone battery replacements, it resulted in about 10 times as many people replacing their batteries as usual (and, coincidentally, far fewer new iPhones sold that year). However, even if your battery is locked inside your phone, you can get a new one and keep your phone lasting longer.
Some Things to Consider Before Replacing the Battery
Even though battery replacements are very useful, they can also be a hassle to get done. In fact it’s not unlike getting work done on your car: You might be able to do it yourself, but it’s probably easier to pay someone else to do it, and you should expect to be without your phone for a while as you wait for the repair to finish. Many places offer same-day repairs, as long as the battery for your device is in stock. That is, for repair places with physical locations near you. If you have a local Apple store near you, they might have what you need. But in some cases you’ll need to mail in your phone to get a repair, which could leave you without it for days. And while you may be able to get a loaner phone from some places, it can still be a hassle. On the other hand, it’s a lot better for the environment, not to mention your wallet, if you replace the battery rather than buy a new phone.
When You Should Replace the Battery
As a general rule, if you’ve had your phone for a couple years and it’s starting to show its age, that’s a pretty good time to look into a battery replacement. That’s right around the time you might be thinking about getting a new phone anyway–many carriers still offer upgrades or payment plans that renew every two years to entice you–but you can also check your battery’s health manually if you want to see if you need an upgrade sooner.
On iPhones, you can navigate to Settings > Battery > Battery Health to find a Maximum Capacity value that will show what percentage of your battery’s initial charge capacity is left. This isn’t how full your battery is right now but rather how much charge it can hold relative to how much it could hold when it was new. If this gets down to 80 percent (especially if it’s still under warranty), get a new battery.
As always, Android phones are a little more complicated; there are many different models and they don’t all work the same. Instead, you can use an app like AccuBattery to get detailed stats on the health of your battery. The app uses an estimate, not an official report, and it may take a few days to get a full picture of your battery’s health. But if it’s below 80 percent of its original capacity, it might be time to take a look at a replacement battery.
Take Your iPhone Into an Apple Store
If you have an iPhone and you want a battery replacement, you’re probably in the best position. If you’re still under warranty or AppleCare+, you can get a free battery replacement on most phones from the last several years. If you’re outside of coverage, the fees range from $49 to $69, depending on which phone you have.
If you can bring your phone into an Apple store, they can often repair your phone the same day and have it back to you in a few hours. If the repair job is more complicated, the store may need to send it off to an Apple Repair Center, which can take up to 3 to 5 days to complete the repair. However, this is how long it would take to get a repair job if you mailed the phone in yourself anyway, so it makes sense to try an in-store repair first.
Try Third-Party Repair Shops for Android Phones
For Android phones, there’s no single manufacturer that also handles all repairs, like there is with Apple, but you can still get same-day repairs done with third-party repair shops. The most prominent of these is uBreakiFix, which has locations in most US states. Some major manufacturers like Google and Samsung give uBreakiFix access to OEM parts, which means they can repair your phone with the same materials those companies would use if you send them in directly.
Prices on Android battery repairs can vary, but usually are around or below $100, but you might need to call in to get an estimate. In some places, the company can even send a rep out to you to repair your phone on-site, in addition to the usual options of either going into a store or mailing in your device.
When All Else Fails, Do It Yourself
In some cases, it might not be feasible (or even possible) to bring your phone into a store or mail it in somewhere. If you really want to keep your existing phone, and you don’t mind getting your hands dirty, you can try replacing the battery yourself. Repair site iFixit has guides for replacing batteries on most major phones that will explain in detail what tools you need and how to take apart your phone, with pictures for every step.
You might need a specialized toolkit that has the proprietary screwheads and other tools that might be required for opening up your phone. Also keep in mind, while you can replace a part without voiding your warranty (and in fact those warranty-voiding stickers are illegal!), the manufacturer still might try to fight you on the warranty if you break anything while doing so. And potentially even if you don’t. If you’re comfortable with that–or if you’re already out of coverage anyway–then order a replacement battery for your phone online and give it a whirl.
If you’ve noticed that your Android phone or tablet’s battery is draining quickly, you’re not alone. Many factors can contribute to rapid battery depletion, but don’t worry; there are also several strategies you can employ to extend your device’s battery life.
Reasons for fast battery drain.
There are several potential causes if your Android device’s battery is draining quickly:
Screen brightness: A bright screen can drain your battery quickly.
Background apps: Apps running in the background can drain your battery even when you’re not using your phone.
Location services: Your phone constantly searches for satellites when location services are on, which can drain your battery.
Battery saver mode: Most devices have a battery saver mode that can help extend your battery life.
Apps consuming battery: Some apps might be consuming more battery than you realize. You can try uninstalling apps you don’t use, or turning off notifications and pop-ups for apps that are useful but draining your battery.
Screen time: If your screen stays on for too long, it can drain your battery.
Temperature: Extreme temperatures can affect your phone’s battery.
Operating system: An outdated operating system can cause your battery to drain faster.
Battery health: Your phone’s battery might be at the end of its life cycle.
Ways to reduce Android battery drain
Here are some ways to potentially reduce battery drain on your Android device: *Note: Can vary based on Android version and device type.
Use Battery Saver or Extreme Battery Saver mode – Battery Saver and power saving modes help conserve battery life. Availability varies across devices – check your manufacturer’s website for details.
When enabled, Battery Saver and Extreme Battery Saver modes may pause most apps, turn off features and slow processes, which may include:
Only update app content (email, news, etc) when opened.
Stop location services when screen is off.
Prevent apps running in background unless Battery Optimization is turned off.
Not respond to “OK Google” hands-free commands.
Turn on Dark theme.
Delay notifications.
Turn off always-on display.
Switch 5G phones to 4G.
Limit internet connectivity and location access – Minimising mobile data, WiFi, Bluetooth, location services when not needed can help conserve battery. Turn on Airplane mode when mobile data isn’t required. Also avoid battery draining apps like cameras and games. Don’t keep lots of apps running in the background.
Use dark colour themes – Using dark mode/theme on your device and apps can reduce battery drain, if available. Helpful for avoiding bright light stimulus at night and sleep concerns. To enable:
Open Settings app.
Tap Display.
Turn Dark theme on or off.
Fixing Android battery issues.
If the battery seems to drain very fast even after following the tips above, there could be an issue with your Android device. Try: *Varies by Android version and device.
Restart your phone – Restarting can sometimes fix battery related problems. Long press the power button and tap Restart in the prompt. Restart method varies across devices – check user manual or manufacturer support pages.
Update Android – Updating to the latest Android version can potentially fix battery issues.
What to do if Android battery issues persist?
If these steps don’t help, consider replacing the battery. Hardware issues like degradation may require a new resolution. Factory resetting can also fix persistent trouble – backup data first. If battery problems continue despite these fixes, check with your device manufacturer or purchase retailer for further support. Review your usage patterns, settings and config when the Android battery seems to drain fast. Fixing issues one by one could help resolve problems. If not, you may consider upgrading your device to a newer model with higher battery capacity.
There are multiple reasons why a lithium-ion battery may swell. There is usually one underlying cause for this to happen, though. Batteries usually swell because gas builds up, creates pressure, and expands them. With that in mind, we must consider the more common causes for a battery to store gas. Manufacturer defects can happen. If the battery maker doesn’t make the battery correctly, gas can slowly build up during the charging process. This essentially means simply charging your phone enough times could be an issue, especially considering juicing up your phone also creates heat.
Swollen lithium-ion battery, modern smartphone, broken smartphone, battery-powered explosive electronics
Heat commonly speeds the process, too. You should probably make sure not to leave a phone in the sun too much, or next to very hot items. Additionally, physical damage to the battery can be a very common cause of battery swelling. Have you ever dropped your phone? Maybe you accidentally punctured the battery? This could be why your battery is swelling. Not to mention, batteries get old, too. Chemical reactions can change, and parts weaken. By the way, this shouldn’t be a common occurrence. Unless there’s a severe manufacturer defect, most batteries should last the couple or few years most users keep a device.
How to know if your phone battery is swollen
It’s much harder to tell if your battery is swelling these days, as handsets with removable batteries are becoming very scarce. We never really see our batteries anymore. This makes it harder to identify a swollen or damaged battery.
The easiest way to tell if a battery is swollen is by inspecting the device (or battery, if you can). Are there any bumps? You may notice an unusual wobble when you lay it on a flat surface. Also, look for warped shapes or signs of the phone disassembling itself. Smartphone backplates start to come off as the battery’s swollen shape puts pressure against them.
While not as safe, the smell can also signify a swollen battery. We wouldn’t advise that you actively try to inhale chemicals, but this is something you may have accidentally noticed already. Does your phone smell odd? People describe a bad battery smell as metallic, and sometimes even sweet.
Even simple things like battery performance can be a dead giveaway. If your battery is charging too slowly, or the charge isn’t lasting as long as it should, this may be a cause of concern.
What to do if your phone battery is swollen
So you’ve found something odd with your smartphone’s battery. Is it safe to use a swollen phone battery? Definitely not! A swollen lithium-ion battery can be very dangerous. The pressure can make gases escape, and the battery can even catch fire or explode, especially if pierced. Your first step should be to turn off the device immediately, and keep it off. Don’t plug it in or mess with it, either. Leave it in a safe place and keep it there, preferably away from anything that can burn. A swollen lithium-ion battery can be very dangerous! If it’s possible, and safe to do so, you should probably remove the battery. Just be careful not to mess with it too much in the process, and try to avoid smelling any fumes it may give off. We actually recommend taking the phone to a professional instead. Technicians will have the necessary knowledge and tools to do this easily. They can also find a suitable replacement for you. This will likely incur some charges and require replacement purchases, though. If your phone is still under warranty or has insurance, your best bet is to go with the carrier, retailer, or company handling the coverage.
How do I stop this from happening in the first place?
Well, you won’t always be able to stop this. That’s just something you’ll have to get used to. That said, there are a few things you can do to minimize the risk of stumbling across a bulging battery in the future.
Don’t let your gadgets get too hot
High temperatures can speed up the rate at which the electrolyte goop decomposes, which could contribute to gases building up inside a battery. And even if that heat doesn’t make a battery bulge, Mitlin says, it will definitely take a toll on how well the battery will work down the road.
Thankfully, many of your gadgets include features to prevent them from running at high temperatures for long periods. Your phones, for instance, will warn you when they get too warm — once that happens, they’ll start to shut off certain features and dial down the brightness of their screens. Worst-case scenario, they’ll shut themselves off entirely until they cool down.
Laptops are generally better at dealing with heat because they have built-in cooling systems, but with summer right around the corner, you should make sure not to leave any of your tech in a hot car or under the sun for very long.
Keep an eye on batteries’ charge levels
Keeping a battery at a high state of charge is a great way to put extra wear on it, so do your tech a favor: Don’t keep it connected to a wall outlet all the time. The opposite is also true: For slightly different chemical reasons, that all-important electrolyte goop also degrades when a battery is fully dead, according to Viswanathan.
That’s right. Keeping your gadgets fully charged and fully dead could contribute to battery swelling over time.
Advice: Once your gadget’s battery hits 100 percent, unplug it and use it as you normally would. Then, once you get down to the 10 to 20 percent range, charge it again.
Try not to drop anything
We know it’s easier said than done.
Usually, if your laptop tumbles out of your hands, the first thing you would worry about is whether its screen is still in one piece. But Viswanathan says these kinds of tumbles could lead to situations where one part of the battery is getting more charged than others. That could lead to battery swelling, as well as some other less-than-pleasant outcomes.
Some devices, like certain laptops, are more vulnerable to this than others because of where their batteries are stored. If your laptop has a battery you can remove yourself, it might be worth keeping it in a protective sleeve when you run around with it. Ditto for phones and tablets: A good case should help keep everything, including the battery, from getting banged up too badly.
Have you acclimated to the sub-par performance of your iPhone and accepted it as part of the drudgery of life? Has restarting your crashed iPhone become routine and ritual? Do you long for the days when your apps loaded swiftly, and you could watch Youtube videos ‘til your battery was at 5 percent?
Everyone knows that there’s nothing worse than a bad iPhone battery.
There are some signs you can use to tell when your battery has reached the point of no return. Some of these signs are baked into iOS, whereas others could be more physical symptoms you’ll notice when you use the iPhone. Regardless, we’ve listed major pointers for when it’s time to get a new battery.
1. Your battery outgrew your iPhone
Why are you even reading this? If your battery has outgrown its case, it obviously needs to be replaced! Even if it’s not swelling this badly, immediate action should be taken to dispose of the battery safely. But, beware: You do not want to puncture the pack and release its toxic contents. Early signs of a swollen battery include: a hazy white screen, separation between screen and phone body, or “squishiness” of the screen (no visible separation, but your screen moves a bit when you pinch the edges of your phone).
2. Your iPhone shuts down unexpectedly
If your iPhone suddenly shuts itself down when the battery is half-drained or so, the calibration may be off. To re-calibrate your iPhone, follow these steps:
Use your iPhone until it shuts itself down due to low battery.
Plug your iPhone into a reliable charger using a reliable cable and let it charge uninterrupted until it reaches 100 percent.
Once it’s fully charged, perform a soft reset by holding your sleep/wake button and your home button until the Apple logo shows up. If you have an iPhone with Face ID, quick-press the volume up button followed by the volume down button. Then, press and hold the sleep/wake button until the Apple logo shows up.
If that doesn’t solve your battery woes, then the battery may be the culprit and will require replacement.
3. Your iPhone Frequently Overheats
Although there could be other reasons why your iPhone overheats, once you rule out everything processor or software-related, it only leaves the battery as the culprit.
When batteries age, the chemical components become less fluid, and that causes what we call a high internal resistance. It makes it more difficult for your iPhone to draw energy from the battery, and this high resistance (similar to friction) causes more heat than normal.
It’s not just aged batteries that can cause abnormal heat but damaged batteries, too. If you have a faulty battery damaged by water or a puncture wound, the chemical balance can get disrupted, which can lead to overheating or even health risks.
So, if you notice your iPhone getting extremely hot while doing the most mundane things, it might be time to get its battery checked.
4. Reduced Battery Life
It’s common to hear people say that their phone used to last the whole day, but now it barely makes it to lunchtime at work. And a lot of people might blame it on software rather than hardware. You may have even tried all the iPhone battery-saving tips, only to still experience a woefully subpar battery life.
Typically, this means that your battery has degraded to the point where it can no longer keep an optimum charge. iPhone batteries are lithium-ion (Li-ion) batteries, and they generate energy through chemical reactions. With time and use, these chemical reactions lose their potency, and your phone will no longer be able to support peak performance.
While all iPhone batteries degrade with age, there are steps you can take to maintain your iPhone’s battery health so it lasts as long as possible.
5. Battery Health Is Less Than 80%
One of the many advantages of iOS over other mobile operating systems is the synergy between hardware and software. Because Apple makes its own hardware and software, it can tie the two together in a way Android or other operating systems can’t. This synergy extends to managing your iPhone’s battery health.
You can monitor your iPhone’s battery health through the Settings app to judge when it’s time for a new battery. Go to Settings > Battery > Battery Health & Charging and note its Maximum Capacity. If the number there reads below 80%, it might be time to change your battery.
In fact, you will see a notification at the top of the page warning you to take your phone to an Apple Authorized Service Provider. Also, if you have an AppleCare+ warranty, Apple will replace your iPhone battery only if its health is below 80%.
However, sometimes, you should take the figure there with a grain of salt. If the number is suspiciously low (or even high), it might be time to calibrate your iPhone’s battery. Calibrating the battery is essentially resetting it so the percentages are more accurate.
