This situation is usually caused by the fault of the phone charger. If the actual output voltage of the mobile phone charger is lower than the rated output voltage, then during the charging process, when the mobile phone battery voltage rises to a certain value, but the battery is not fully charged, the current voltage of the mobile phone battery is consistent with the output voltage of the charger, so that there is no voltage difference and cause the charging to stop. It is recommended to replace the charger for testing. The iPhone may heat up slightly while charging. To extend battery life, if the battery is too hot, the software may limit charging after 80 percent power.
The iPhone will charge again when the temperature drops, so try moving the iPhone and charger to a cooler location
1. Charge the device. For example, if the data cable or charging head is abnormal, replace the test respectively.
2. The battery is faulty. For example, loose, deformed, etc., replace the battery.
3. The software is faulty. General brush machine can be solved
4. The hardware is faulty. For example, the charging interface contact is poor, etc., send for repair.
5. Others. For example, too much software is running in the background, resulting in less input than output, causing no charging phenomenon.
6. Run out of power, battery protection. Activation method: Unplug the data cable of the phone after 10 seconds of direct charging, and then charge for 5 seconds, and then charge after unplugging.
