What Am I Using?
Battery not charging?
Check whether the device recognises the charger, whether charging has paused and what to try with a compatible charger and cable.
Does the device recognise the charger?
Look for a charging light or a plugged-in icon. Check both ends of the cable and use a compatible power source.
Device and operating system
Check the charge limit and power supply
Some devices deliberately pause at a configured percentage. A low-power charger may only slow the discharge.
- Read the battery status and look for a charge limit or temperature warning.
- Use a compatible charger of the maker’s recommended power rating and compare with the device idle.
Check the outlet, cable and port
A failed outlet, incompatible cable or damaged port can prevent the device recognising power.
- Try a working outlet and the correct charging port. Use an undamaged, compatible charger and cable.
- Stop using a damaged, unusually hot or swollen device. If a known good charger is still unrecognised, arrange service.
Check the charger against the device manual
A plug that fits may still supply too little power or use an unsupported charging standard.
- Verify the charger and cable rating using the manual or manufacturer’s listing.
- Tell support the model and what the lights do. Keep damaged cables disconnected.
