New Battery Draining very quickly
Wondering if you could assist with a strange fault.
I have a iphone 5s which I have now replaced TWO original iphone 5s batteries ( I repair phones for a living and have never had this issue)
The problem with both batteries is the following, I charge to 100% and then put it into airplane mode . I leave overnight and within 12 hours the charge has dropped to 50%.
The phone has been factory reseted and has been set up as a blank phone (no apple ID etc).
I do notice the charging symbol stays on once the battery hits 100%
Any advise would be appreciated
Is this a good question?
