new battery - phone shuts itself off at 50%
I received a new display and battery for my iPhone 8plus from the iFixit store and installed both yesterday.
I am really happy about the display but I do have an issue with the battery:
I am unable to calibrate it, because after recharging it to 100% and letting it drain, the phone turned itself off at 50%.
I connected it back on charge and it showed 50% battery.
I tried again, and again at 50% the phone turned off, but this time restart it showed a 14% battery charge, although usage shows 50%
Don't really know how to make it work.
Screenshot1: first attempt: Phone turned itself off at 50%
Screenshot2: second attempt: turned itself off at 50%, then on restart shows 11% battery
The screen has been broken for a while now and my original battery was kind of wearing off so I decided to change both.
No drops and then battery doesn’t get specifically hot (normally when recharging)
Was a pretty standard swap, I suppose
