Why Doesn T My Phone Charge Over 80. To extend the lifespan of your battery if the battery gets too warm software might limit charging above 80 percent. Your iPhone might get slightly warmer while it charges.

But your phone isnt always great at measuring thatif your battery has degraded to 95 of its original capacity your phone might still report that as. Batteries naturally degrade over time and their capacity slowly decreases. My One is doing exactly the same thing and it doesnt seem like its the battery.
Change charging location to a cooler location.
They might not provide enough amperage to charge the device or too much therefore affecting the battery. These batteries dont like to sit for a long time either full or empty - best if theyre stored about half full. If your device charges normally it means there is a problem is with your adapter and you must replace it at the earliest to solve my phone wont charge the issue. In order for it to be statistically relevant with current battery technology youd probably have to aggressively sustain such charging habits long beyond the feasible operating lifetime of the battery and it would have already died through general wear and tear or been replaced with a phone switch.
