6 Common Signs It’s Time To Replace Your iPhone Battery

Stopping your iPhone battery from expiring is impossible— like most things in life, it has its expiration date. Unfortunately, when the time comes, your phone won’t be as awesome as it was when the battery health was up there. Luckily, you can always replace it with a new one and have your device working at an optimal level once more. 

Before then, there are some signs that can tell your iOS battery has reached its point of no return. While your device can pinpoint some of the symptoms and warn you, you can also observe some physical signs. Regardless, we’ve revealed some of the common signs to know it’s time to replace your iPhone battery.

1. Your iPhone Battery Drains Quickly 

One of the most obvious signs of a bad iPhone battery is that it runs out faster than it should. You’re using your phone and notice that the percentage goes down faster than normal. Phones use lithium-ion batteries which are built to last for a certain number of cycles.

A cycle isn’t counted by the number of times you charge your phone, but by every time the battery is drained to 100% of its capacity. For example, a cycle can take up 75% of your phone’s battery and when you charge it, it doesn’t end there. By using 25% the next day, that still represents the complete cycle even when the charge was interrupted.

As the battery chemicals expire, you may notice a change in the charge cycle, which is more quickly. If care is not taken, it may affect the lifespan of the phone. In essence, as your battery degrades, you’ll experience a faster charge cycle, which means the phone will need to be charged more frequently. As you may already know, this is a clear sign that your iPhone Battery needs to be changed.

Similarly, if extreme temperatures seem to be the issue, avoid using your iPhone outdoors for long; especially using resource-heavy apps, like Snapchat or YouTube.

This phone can link the two together in a way another operating system can thanks to the way Apple manufactures the hardware and software.
