We usually have a habit in fueling our phone fully. Some even charge them from zero to 1oo%. However, it’s not a good way to maintain the iPhone battery strong. A battery can be full from 0 to 100% about 300 to 500 times before it expires. This full charging thing can cause stress to the battery and reduce its life. But if you just charge the phone from 0 to 50%, that battery can go through 1,200 to 1,500 times of charging.
To keep your iPhone battery long life, don’t let your iPhone get to the low battery. You should fill it when the battery left is about 30%. And then, charge it to 80%. That’s a level where the battery is most comfortable and effective. This can help you to triple, or even quadruple the recharge time. So, stop charging your cell overnight. Instead of that, charge it shorter and more frequently.
