Choose the symptom
- Battery, charging and heat need different checks.
- Connection failures should be separated into Wi-Fi, cellular, SIM/eSIM and Bluetooth.
- Keep a backup before any action that may remove settings or data.
A safe order
- Confirm the scope and any service outage.
- Try settings and a normal restart, then reassess.
- Use reset or repair only when the earlier checks justify it.
