Restart the vehicle after the update is complete.

3. Analyze Energy Consumption

Navigate to the "Energy" tab on the vehicle's touchscreen.
Review the "Trip" and "Last Charge" sections to identify spikes in energy consumption.
Adjust driving habits or settings based on the findings (e.g., reduce climate control use).

4. Inspect Battery Health

Use the Tesla service tools to run a battery health diagnostic.
Check the voltage and temperature readings against manufacturer specifications.
If the battery health is below acceptable standards, consider battery maintenance or replacement.

5. Check for Excessive Power Drain

Disable any features that may be consuming extra energy, such as "Always On" features, heated seats, and climate control.
Monitor the vehicle for changes in battery consumption after adjustments.

6. Physical Inspection

Inspect the battery pack visually for any signs of damage or abnormal wear.
Ensure all connections are secure and free from corrosion.
If damage is detected, consult with a Tesla technician for further evaluation.
