Iphone 11 battery performance when using apps
Hi All, I signed up for a three year cointract with my Service Provider in July 2022. I was very happy and as i am now retired figured it would be my last phone. All was good and I could use the phone with ease as it gave me the option to zoom text (Ionly have 40% vison left) and use Siri to read my messages coming in and I could answer them witrh ease. Suddenly one day the phone issued an 'overheating' warning while I was watching short videos. , I put the phone down and left if for the night., The next morning it was ok but every time used an app the bateery drained at an alarmign rate, I could not lisaten to anythign unless the volume was at 100%.
If I leave the phone and ont uuse it then the battery lasts a long time so I dont think it is a battery problem per se. As the phone is still under warranty I called my service provder and they said to bring it in and confirmed it was still uder warrantly... As luck wouldahave it , as I was removing the sim card so my son could take it in for me I dropped the phone and it made a small chip on the screen so when my sone got the phone to the repair center thewy wouldd not even loook at it as they said I had "abused" the phone.. So here I sit with just ovr two years lleft on my contract on a phone whose battery will not last past an hour or two... Can an yone advise me as to what could be the problem? The battery drains witban any app I use so I cannmot pinpoint a specific app.. has anyone else hafdd this issue at all with a possible remedy? As I say, it only statered after the phone overheated
Would appreciate any assistance or advice....
Kind regards
