Check these first
- 1 of 4Check the cable and the adapter
Look for breaks or bent prongs. Apple says not to use damaged accessories. Try a different cable and adapter.
- 2 of 4Look inside the port
Apple says to remove any debris from the charging port on the bottom of the phone. Lint packs in tight: if it does not come out easily, bring it in.
- 3 of 4Stops at 80 percent?
That may be on purpose. Optimized Battery Charging can wait before charging past 80 percent, and iPhone 15 models and later can have a charge limit set.
Settings › Battery - 4 of 4Says liquid is detected?
The port is wet. See Phone fell in water: what to do.
When it needs a repair
It charges only at an angle, the plug feels loose, or nothing works with a cable and adapter you know are good: the port likely needs a repair.
