Before you start
Have the phone model and a compatible, undamaged cable and adapter ready. Wireless-only problems need your model’s wireless-charging instructions.
Try these steps in order
Test after each step. If the problem is resolved, you can stop.
Check for a warning
If a moisture or temperature warning appears, follow your manufacturer’s instructions before reconnecting power. Do not override the warning.
Test a known-working power source
Use a wall outlet and a compatible charger. Inspect the cable without bending or forcing it. If possible, swap the cable, then the adapter, testing separately.
Inspect without poking
Look at the port with a light. If the connector will not fit normally or debris is stuck inside, have it cleaned professionally.
Give an empty battery time
If there is no damage or warning, leave the phone connected for about 30 minutes before trying again.
Restart using the model’s instructions
Try a normal restart if the screen responds. For an unresponsive device, use the manufacturer’s model-specific restart instructions—not a factory reset.
What your result may mean
- A different cable works
- The original cable is a likely cause; stop using it.
- It rings but the screen stays black
- Ask for display diagnostics rather than assuming the battery failed.
- Charging pauses around a set percentage
- Check the device’s charge-limit or battery-protection settings before replacing anything.
Still not working?
If known-working accessories and a model-appropriate restart do not help, contact the manufacturer or an authorized repair provider. Note the warning message and accessories tested.
