). However, when I put it on charge, it would only charge for a few minutes before saying it was fully charged. When I unplugged it, the battery percentage would drop rapidly and the phone would eventually die again. I tried several different chargers and cables and even took it to the Apple store, but they couldn't find any issue with the phone itself. Finally, I came across a forum post that suggested resetting the phone's battery calibration by fully charging it, then letting it die completely before fully charging it again. This seemed to do the trick and my phone is now back to working normally.
