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.

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.
Android smartphones and bad battery life is a never-ending love affair. Despite the efforts of smartphone companies to improve battery performance through software optimization, adding features such as optimized charging,users just can’t help but grumble about their Android phone’s battery life.
Users often complain that their Android device discharges very quickly or their phone unexpectedly shutdowns in the middle of the day. The reason behind, quite often, this is the fact that the battery of their Android smartphone isn’t calibrated properly. In such cases, the displayed battery percentage fails to align with the actual charge level.
The batteries of new smartphones, and often those of old ones as well, need to be calibrated. This procedure is usually done in the factory, but it should be repeated many times, and it certainly doesn’t hurt.
This is because in some cases, the operating system indicates a charge level that is DIFFERENT from the actual charge of the battery, and in many cases, this ‘reading’ problem translates into a shorter duration of full charges.
Therefore, in this article, we will learn more about battery calibration on Android—three easy ways to calibrate the battery of your Android device.
Manual Calibration
The best way to calibrate the battery of your Android smartphone is to manually reset the stats. Here’s how you can do it:
Use your phone until it powers off on its own.
Switch it back on and wait for it to turn off again.
Connect your phone to a charger and do not switch it on. Let it charge in the power-off state until 100%.
Once the phone reaches 100%, turn it on. It’s likely that the battery indicator will show a percentage below 100%. In this case, reconnect the charger while keeping your phone on, and continue charging until it shows 100%.
Once it reaches 100%, disconnect it from the charger and reboot your phone. If the battery indicator still shows a percentage below 100%, repeat the steps above until it shows 100%.
Again, use your phone until it reaches 0% and powers off on its own.
Finally, charge your phone once again without disconnecting it in between, and now your phone will show the actual battery readings.
Use a Third-Party App
If you don’t want to follow the manual process, you can consider using a third-party app to reset the battery statistics of your smartphone. There are several apps available on the Google Play Store that can help with calibration. However, many users have reported that these apps are less effective than manual calibration.
Reset Your Device
If nothing works, it’s best to factory reset your smartphone. Remember, this should be used as a last resort when all the other methods fail. also, just make sure you back up your device before performing a factory reset.
Lastly, it’s important to note that this process should not be performed frequently, as excessive calibration (full charging and discharging cycles) can be detrimental to the battery of your smartphone. Only rely on the methods mentioned above if the battery is behaving strangely. If calibration is required more often, it likely indicates a more serious issue (you might need to get that battery replaced).
General Tips:
Use the original charger and cable that came with your smartphone.
Do not fully charge or fully discharge the battery on a regular basis.
Avoid using your smartphone in extreme temperatures, as this can damage the battery.
LITHIUM ION BATTERIES – THE WAVE OF NEW INDUSTRY TECH
Lithium-ion batteries offer some distinct advantages and improvements over other forms of battery technology. Used in many devices today, they provide good performance, charges faster, and lasts longer compared to other types of batteries.
Lithium-ion is a popular choice for portable devices because they offer distinct advantages and improvements over other battery technologies. Like all technology though, there is a difference in how well each one works with certain applications — it’s important to understand not only what makes them good but also their downside.
THE PROS AND CONS OF LITHIUM ION BATTERIES
But the shininess and newness of a technology doesn’t mean it’s without its downfalls. Before hopping on the Lithium Ion Battery bandwagon, take a look at the pros and cons of the product. While the benefits are hard to dispute, there are still some potential drawbacks to consider. Whether you ultimately utilize Lithium Ion Batteries or not, it’s important to be in the know on the latest industry tech and innovation.
Pros:
Lithium-ion batteries are the best type of battery to use in your device since they don’t require any extra maintenance. Unlike other types of batteries that may need periodic discharge or topping off with fluid and priming before you can use them (and who has time for that?), these bad boys will just work every single time without fail!
A lithium-ion battery can be really great when it comes to loading characteristics. They provide a fairly constant 3 volts per cell before they start losing their charge as you use up all of your last charges, which is perfect!
Lithium-ion batteries come in many different types and sizes, which makes them convenient for use in various applications. The rechargeable battery you find inside your smartphone has very specific power requirements versus something like an electric vehicle – so it’s important that before buying or borrowing certain devices we know what type of lithium-Ion they have.
A rechargeable cell may require priming when it first receives a charge. Lithium-ion, on the other hand, has no such requirement, as they are ready to go from the start!
Lithium-ion batteries offer twice the energy density of nickel-cadmium, making their charging capabilities much more robust. This means that a single lithium-ion battery can power an electronic device for up to three times as long before needing recharging compared with two identical counterparts using NiCd or lead-acid technology – this is important in devices such as smartphones and laptops where you don’t want your battery dying out just when it becomes essential.
Cons:
Lithium-ion batteries can be tricky to handle if you don’t know of their flaws. One problem with these types is that they lose power faster than other battery types, such as nickel-cad or NiMh ones which typically have self-discharge rates of less than 5%.
The major disadvantage to lithium-ion batteries is their ageing. The battery can only withstand so many charge-discharge cycles before capacity falls and this could be due in part to the number of times it’s been charged or discharged; typically a li-ion setup will need at least 500 more charges than what you put into them just for safety reasons!
The lithium-Ion polymer(LiPoly) cells were created so you don’t need any external circuits but still maintain long life cycle times due t° the high energy density delivered by each cell!
The other problem with these types of cells, especially those found within consumer electronics such as cell phones, smartwatches etc., has got to do with time-related factors — namely how quickly they age if left unused over several months without use.
Lithium-ion batteries are a type of rechargeable battery that can be used for mobile devices and other portable electronics. The biggest downside to this kind of power source? It needs protection from being overcharged or discharged too much, which usually means including built-in circuitry in both the device itself as well as inside its voltage regulation system (also sometimes called “protection”).
How to Store Lithium-Ion Batteries Safely
Batteries should always be stored in a cool, dry place away from heat and sunlight. If your home does not have adequate ventilation or you’re storing batteries for an extended period of time (more than six months), it’s best to store them at 59℉ with relative humidity below 60%.
Boosting your home security is not just about installing alarms or motion sensors. You need to make sure the batteries in these devices are running at full strength and stored safely and away from children.
1. Leaving a device plugged in will overcharge its battery: False
One of the most common lithium-ion battery charging myths is that plugging in your devices for long periods of time will overload the battery, wearing it out faster than usual. Don’t worry, it won’t. Your smart devices know better. Protective measures built into modern phones, tablets, and laptops ensure that lithium batteries stop charging once they reach capacity.
That said, if you leave your fully charged smartphone plugged in overnight, it’ll experience “trickle charge,” which means that as the battery naturally drops down to 99%, it uses a small amount of energy to bump it back up to 100%. This can cause the battery to wear out slightly faster, but not much faster than just regular use.
2. Freezing your phone battery helps keep its charge: False
Sudden, drastic shifts in temperature are never a good thing for your tech. Exposing your phone, tablet, or laptop to freezing temperatures can not only harm its battery, but also put other internal components at risk of malfunctioning. So never, ever put your devices in the freezer.
Tip: Charge your devices in a cool, ventilated place. Lithium-ion batteries don’t work well in freezing or overly hot temperatures, so avoid laying a stack of magazines on top of a charging phone or sticking it between some pillows, and don’t leave them in direct sunlight. Also, wireless and fast-charging devices can be helpful, but they produce lots of heat, so use them sparingly.
3.Closing Battery-Draining Apps Will Prolong Battery Life: False
In iOS devices, there’s a feature that allows you to close battery-draining apps. However, even if it is possible for an iOS user to turn off battery-draining applications at will, turning them back on again does not mean that the battery life has returned to normal. This option was created so users can get rid of unnecessary background processes and free up memory when they need it most.
4. Recharging battery-draining devices when they are at 20% will make them last longer: False
This battery myth is not true either! It has been proven that charging a battery with up to 80% won’t harm its lifespan or shorten battery life. And if you do need to recharge your battery when it’s still at 20%, you can use battery degradation mode, where your battery will be charged to 50% before stopping. This means that 60% of battery power is left unharmed and untouched during the charging process, which makes this option beneficial for battery health.
5. You need to let your battery hit zero before charging: False
Another cell phone battery charging myth is that you need to regularly drain the battery down to 0%, then charge it back up to 100%. This is true for older, nickel-based batteries, but not so for modern lithium batteries; the back-and-forth charging process will only wear down your device.
Tip: Try not to let your batteries drain down to 0%.
6. Your device’s batteries have a short lifespan: Somewhat false
There are several factors that go into how long your device’s lithium-ion battery will work as it should—how often you use your device and how often you charge it being two of the main ones. On average, you can expect your battery to last 2-3 years, or 300 to 500 charge cycles—whichever comes first. One charge cycle is measured from the time a battery is fully charged, completely drained, then charged back up again.
7. If your battery dies, you need a new device: False
If your device can’t last a full day on a single charge, or if it’s unexpectedly shutting down, your battery is probably starting to go. Other signs include lower speaker volume and sluggish apps. But a dead (or dying) battery doesn’t necessarily mean you have to invest in a new device. A battery replacement can be an affordable way to breathe new life into older tech.
A typical smartphone will only work at optimal capacity for 2-3 years before it starts deteriorating and becomes less efficient in performing basic tasks like taking photos or checking email messages without having power disruptions midway through the process.
But there are ways around this issue! You can replace batteries yourself if needed or get them replaced at a service centre. Here at BATTERYONE.CO we offer various batteries for your smartphones and other mobile devices.
Lithium-ion batteries power the lives of millions of people each day. From laptops and cell phones to hybrids and electric cars, this technology is growing in popularity due to its light weight, high energy density, and ability to recharge.
So how does it work?
THE BASICS
A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator. The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector. The separator blocks the flow of electrons inside the battery.
CHARGE/DISCHARGE
While the battery is discharging and providing an electric current, the anode releases lithium ions to the cathode, generating a flow of electrons from one side to the other. When plugging in the device, the opposite happens: Lithium ions are released by the cathode and received by the anode.
ENERGY DENSITY VS. POWER DENSITY
The two most common concepts associated with batteries are energy density and power density. Energy density is measured in watt-hours per kilogram (Wh/kg) and is the amount of energy the battery can store with respect to its mass. Power density is measured in watts per kilogram (W/kg) and is the amount of power that can be generated by the battery with respect to its mass. To draw a clearer picture, think of draining a pool. Energy density is similar to the size of the pool, while power density is comparable to draining the pool as quickly as possible.
Advantages of Lithium-ion Battery
Now a days Lithium-ion batteries are popular because they have a number of important advantages over competing technologies:
Generally, they are much lighter than other types of rechargeable batteries of the same size. They hold their charge.
They hold their charge. A lithium-ion battery pack loses only about 5 percent of its charge per month.
High specific energy and high load capabilities with Power Cells.
Long cycle and extend shelf-life; maintenance-free. They can handle hundreds of charge/discharge cycles.
High capacity, low internal resistance, good coulombic efficiency.
Simple charge algorithm and reasonably short charge times.
Low self-discharge (less than half that of NiCd and NiMH).
Limitations of Lithium-ion Battery
Requires protection circuit to prevent thermal runaway if stressed
Degrades at high temperature and when stored at high voltage
No rapid charge possible at freezing temperatures (<0°C, <32°F).
Transportation regulations required when shipping in larger quantities.
They are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would..
