Phone Charging Guide
Diagnose cables, chargers, ports, wireless charging, heat and moisture warnings.
A charging problem can come from power source, cable, adapter, port, temperature, software or the battery. Test one known-good compatible component at a time.
Start with the safest checks
Use observation and reversible tests before changing settings. Write down the exact message, recent changes and conditions that reproduce the problem.
- Inspect without inserting metal
- Compare cable, adapter and outlet
- Remove incompatible cases for wireless charging
- Respect moisture and temperature warnings
- Seek service for physical damage
Protect your data and accounts
Back up important information before repair, reset, sale or transfer. Never disclose passwords, one-time codes or full device identifiers in public.
- Verify backup completion
- Use official account-recovery channels
- Keep sensitive identifiers out of screenshots and URLs
Know when to stop
Stop when a phone is swollen, smoking, leaking, physically damaged or extremely hot. Manufacturer, carrier or qualified repair support is appropriate when safe checks do not isolate the fault.
- Do not puncture or open a battery
- Do not use heat, freezing or conductive tools
- Ask about warranty, data handling and cost before repair
