Sometime when I start charging the battery will not increase, after power off it will charge but when it reaches 80%, the battery🔋 will not be increased. Can you tell me what happened to my device iPhone11promax

Hello,


From: If your iPhone, iPad or iPod touch won't charge


If your device stopped charging at 80 per cent

Your iPhone might get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 per cent. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location.

iOS 13 uses Optimised Battery Charging to slow the rate of battery ageing by reducing the time that your iPhone spends fully charged. Your iPhone uses on-device machine learning to understand your daily charging routine so that it can wait until you need to use your iPhone to finish charging past 80 per cent. Charging in this way reduces the wear on your battery and improves its lifespan. Optimised Battery Charging is active only when your iPhone predicts that it will be connected to a charger for a long period of time.


If your phone still has issues with charging and you have tried moving it somewhere cooler or it should be cool enough, visit an Apple Store/Apple Authorised Service Provider or contact Apple Support.
