Apple 13 Battery Maintenance
Don't wait until the iPhone is dead before charging. Try not to charge less than 20%. When the charge reaches 80%, it means that the mobile phone is fully charged and can be unplugged. Because it is not fully charged, it will not be considered fully charged. Fast charging is the same as 5W charger. Without fast charging, the battery will decay quickly.
Fast before charging 80%, and slow after 80%. Turn on and optimize battery charging. Don't play with your mobile phone while charging, which will put a lot of pressure on the battery, especially when the battery is low. Charging all night at night, it is recommended to use 5W charger.
