As early as the official version of iOS 1 1.3, Apple added a brand-new battery health function, which is convenient for users to judge the battery life and whether it is necessary to replace the battery. So what are the maximum capacity and peak performance capacity of battery health function? The maximum capacity is easy to understand, which is actually the current loss of the battery. If it is 100%, the battery has no loss; If it is 98%, it means that the battery has a loss of 2%.
Peak performance capacity is the key to determine whether a mobile phone is down-converted. Generally speaking, when the maximum capacity of the battery is 70- 100%, it means that the condition of the battery is sufficient to support normal peak performance. If the maximum capacity of the battery is less than 70%, it means that the mobile phone needs to replace the battery.
So how to improve the service life of the battery in daily use? First of all, try not to charge the mobile phone when the battery is less than 20% or even automatically turned off. Secondly, try to use the original charger to charge, which is not only efficient, but also safer. Finally, staying away from high temperature, humidity and magnetic environment will not only consume electricity quickly, but also damage the motherboard of the mobile phone and shorten the life of the mobile phone.
Your iPhone is now in a state of several charges a day. Go and see if your iPhone needs to be replaced!
