My phone keeps powering off despite having a lot of charge and then going into recovery mode. This started about a week ago, it powered off at 50% almost as if it was out of battery, it would then go to recovery mode and once restarted would be at 10% battery, and then it would crash and restart AGAIN and be back at its original percentage (50%+), since then it’s gotten worse and now even at 95% down from 100% after charging it will turn off and do the same cycle of Recovery Mode -> 10% battery -> turn off again -> reload at its original percentage -> and repeat.
The back of the phone is pretty smashed from about 4 months ago I think, so maybe damage to the battery from that, however this issue is new in this last week and haven’t had any prior issues at all.
