Solution

1. Battery Health Assessment

Use the Tesla app to access the battery health report.
If the battery capacity shows significant degradation (below 80% of original capacity), consider contacting Tesla service for further evaluation.

2. Review Energy Consumption Settings

Navigate to the energy consumption screen on the dashboard.
Disable unnecessary features such as 'Always On' or 'Sentry Mode' when not needed.

3. Optimize Climate Control

Set climate control to use 'Scheduled Departure' mode to precondition the cabin before driving.
Use seat heaters instead of cabin heat when possible, as they use less energy.

4. Tire Inspection and Maintenance

Check tire pressure and inflate to the recommended PSI as per the owner’s manual.
Inspect for uneven wear; if found, rotate or replace tires as necessary.

5. Software Update

Go to the software section under 'Settings' and check for updates.
If an update is available, install it to ensure the vehicle operates with the latest efficiency improvements.
