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.
