The phone is not charging. I then fitted a new battery which showed 100% right up until the battery was exhausted. Can anyone tell me whether this is down to a part that can be changed or is this controlled by the logic board?
Sounds like there may be a fault with your gas gauge, To check. Download a piece of software for your computer called “I backupbot” With it open and your phone plugged into your computer click on your phone, then click more information. It should tell you wether your gas gauge is functional
