3. Battery Health Check

  • Open the Tesla app and navigate to 'Service' -> 'Battery Health' to view the current state of the battery.

4. Check Charging Components

  • Inspect the charging port for foreign objects or damage.
  • Clean the charging port gently with a soft cloth if necessary.
  • If the charging cable appears damaged, replace it with a genuine Tesla charging cable.

5. Update Software
