Changed battery and device switches off randomly -
I recently changed an iPhone 5S battery and now the device will turn off at random times between 30% & 70%, and not come back on until the device is plugged into a charger.
The device then turns back on at whatever percentage it went off at, continues to operate for a bit then goes off again.
If I plug the phone into my Mac and look in coconut battery it has 3 cycles and the health jumps between 84% and 98%, giving a different reading every time I plug it in.
Can anyone advise what the problem could be?
Is dit een goede vraag?
