The reasons why iPhone is charged not completely and how to make it charged to 100%
There are two main reasons for charging the iPhone only to 80%
- Enabled "Optimized Charging" in the iPhone settings.
- Overheating of the device and its battery.
As for the first point, it first appeared in iOS 13 and is usually enabled by default. Its essence comes down to the following: iPhone "studies", how exactly you use your phone and, if it is assumed that in the near future you will not find yourself for a long time without access to the charger and you will not actively use it, charging will be made only to 80%, Since it allows you to extend the life of the battery.
If you do not need this function, it is easy to turn off:
- Go to the settings - the battery is the battery status.
- Turn off the "Optimized Charging" item.
- Select whether to disable this option only until tomorrow or forever.
Ready, now regardless of what will assume iOS on the use of the device, the charge will always be performed up to 100%.
The second situation, when the battery charge can be limited - strong heating of the device or battery, as it can also damage it. In what cases it can happen:
- Using games and heavy applications on the iPhone with simultaneous charging.
- The phone is located in the sun or in a hot room when charging.
- The use of non-original cables and chargers (it is strange that the cable can affect, but it really is so).
- Phone covers interfering with heat removal.
Also, if the battery faults (especially if replaced with the original or physical damage), its charging can cause strong heating, resulting in the end that the charging process will be stopped.
