If the device stops charging at 80% charge

iPhone may get a little warm when charging. To extend battery lifespan, if the battery becomes overheated, software may limit charging when the charge exceeds 80%. When the temperature drops, the iPhone will charge again. Try moving the iPhone and charger to a cooler location.

iOS 13 and later can use the Optimized Battery Charging function to reduce the time the iPhone is fully charged, thus slowing down the aging of the battery. iPhone uses on-device machine learning to understand your daily charging habits and suspend charging to more than 80% until you need to use your iPhone*. Optimize battery charging" will only take effect if the iPhone predicts that it will be connected to the charger for a long time.

* Information about charging habits is only stored on iPhone. The information will not be included in the backup or shared with Apple.
