First, check your iPhone's battery capacity in the Settings app. If it's below 80%, it may be time for a battery replacement, though we still can't rule out a software or firmware issue.

Next, try restarting your iPhone. This can fix a minor software bug. If that doesn't work, back up your iPhone and put it in DFU (Device Firmware Update) mode. A DFU restore erases and reloads every line of code on your iPhone.

If your iPhone battery still isn't calibrated after a DFU restore, you may have to get your iPhone repaired.
