Probably not buy i’ll ask anyway.
My iPhone battery is lasting an hour (ish) before I need to plug in the charger. I’ve had the phone about 3 years and I think it was my sister’s for 2 years before that so it’s possibly 5 years old. There’s absolutely nothing wrong with the phone and I’ve just paid £55 to repair a cracked screen so don’t really want to have to replace the phone. (I can’t afford a new one anyway so it won’t be happening)
Is there anything I can do other than removing unused apps using battery saving mode to give the battery a new lease of life?
