Start with the simple checks. Change one thing at a time so you can tell which step helped.
A worn cable, dirty port, weak power source or battery fault can stop charging. First, note what changed recently and whether the same issue affects another device. This helps separate a device-specific fault from a wider network or service issue.
Troubleshooting steps
Check the basics
Try a known-good wall outlet and compatible charger you trust. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Review the settings
Inspect the cable and charging port in good light; do not insert metal objects. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Test one change
Restart the phone and allow a few minutes for the battery indicator to respond. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Confirm the result
If the phone supports wireless charging, compare it using a compatible charger. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Helpful note
Stop charging if the device gets unusually hot, smells burnt or shows physical battery damage.
When to get more help
If these checks do not resolve the issue, contact the relevant device maker, internet provider or app support team. Include the exact model, software version, any error message, what you have already tried and when the problem began. Avoid sharing passwords, verification codes or private account details in a public forum.
For equipment that is hot, damaged, wet or making unusual electrical sounds, stop using it and seek qualified support. Do not open power supplies, batteries or mains-powered equipment.
Settings and menu names vary by model and software version. Use the manufacturer's current instructions for device-specific steps, and back up important files before making changes that could remove data.
