? 1. If the iPhone is equipped with a thick protective case, metal protective case or battery case, it may not charge or charge slowly, please try to remove the protective case first.
2. Your iPhone may heat up a bit while charging. To extend battery life, if the battery overheats, the software may limit charging when it reaches 80%. When the temperature drops, the iPhone charges again. Try moving your iPhone and charger to a cooler location.
If you use your phone while wireless charging, it is recommended to stop using your phone temporarily due to the possibility of position shifting, which may cause suspension of charging or the phone becoming hotter.
3. Check whether the Optimize Battery charging function is enabled. When Optimized Battery Charging is enabled, a notification appears on the iPhone lock screen indicating when the iPhone will be fully charged. If you need to fully charge your iPhone as soon as possible, hold down the notification and tap \"Charge Now.\"
Or go directly to the iPhone \"Settings\" - \"Battery\
Should be due to the open charge protection, so the charge can not be charged.
The reason why the P40pro does not charge when it is charged to 80% is that the battery health option of the setting Lee is turned on, and it is OK to change it to the default.
