Apple's charging mechanism is to divide the charging process of lithium batteries into two layers. The first 80% is to charge the mobile phone quickly to get more power, and the last 20% is to trickle the slower current to extend the battery life. The research of BatteryUniversity shows that the battery is in a high voltage state after being fully charged, which is more harmful to the battery.
This is a cycle. If each discharge 100% is recharged, a cycle will be completed. The battery capacity of lithium battery decreases with the increase of charging cycle, so it allows you to complete a charging cycle several times while using it to prolong the battery life.
Try not to play while filling in.
Playing while charging has the greatest impact on the battery life of the iphone. According to statistics, playing while charging will accelerate the battery capacity loss by as much as 30%, and sometimes even the high temperature will damage the internal components of the mobile phone. Even if you charge your mobile phone, you should avoid playing games and other high-intensity loads and keep the temperature of your mobile phone within a reasonable range.
If the equipment is not used for a long time, there are two key factors that will affect the overall operation of the battery: ambient temperature and the percentage of battery charge before power-off storage.
Apple iPhone charging precautions:
1. There is a saying that it takes 12 hours for the iPhone to be fully charged for the first time, but this is not the case. Lithium batteries don't need to be fully charged for the first time.
2.iPhone can be charged when it is used, which has little effect on the battery.
3.iPhone has overcharge protection function, but it is recommended to unplug the phone after it is full, and it is not recommended to charge it for a long time.
4. When the iPhone is charged to 100%, unplugging the charger is the best time. After charging to 100% for one hour, the battery power when the charger is unplugged is not as good as that when it is fully charged to 100%. In other words, after being fully charged, the iPhone has entered the overshoot protection and stopped charging, and the next time is only the battery consumption process.
5. When the battery capacity of iPhone is low, it should be charged in time to maintain the battery life.
