Symptoms
- Battery percentage rises but no lightning bolt icon appears
- Lock screen doesn't show the charging animation
- Icon appears intermittently while cable is connected
- Icon is missing after a recent iOS update
Likely causes
- CommonMinor software display glitchThe battery icon occasionally fails to refresh even though charging is working correctly underneath.
- CommonLoose cable connection causing charging to start and stopIf the icon flickers rather than staying solid, the connection itself may be intermittent.
- PossibleLow Power Mode or certain display settings hiding the animation brieflySome display states change how charging is indicated.
- PossibleA charging fault where the phone isn't actually receiving powerIf the percentage isn't rising either, this is a real charging issue, not just a missing icon.
What to do
- Check whether the battery percentage is actually increasing over a few minutes; if so, it's charging despite the missing icon.
- Wake the screen by tapping it, since the icon sometimes only appears on an active screen.
- Ensure the cable is fully and securely seated in the port.
- Restart the phone to refresh the display and status icons.
- Update iOS if an update is available, since display bugs are often fixed in updates.
- If the percentage is not rising, treat this as an actual charging failure rather than a cosmetic issue and check the cable, adapter, and port.
- Try a different cable and adapter to rule out an intermittent connection causing both the flicker and the missing icon.
- Note whether the issue happens with every charger or just one, which narrows down cable versus software.
When to call a pro
If the percentage genuinely isn't rising despite a good cable and adapter, treat it as a charging port or battery issue rather than just a cosmetic one.
