Solution

1. Battery Health Check

Sub-steps:
- Navigate to the “Battery” section in the Tesla app.
- Review the health report and note any alerts or warnings.
- If the battery's state of health (SoH) is below 80%, consider contacting Tesla support for evaluation.

2. Software Update

Sub-steps:
- Connect the vehicle to Wi-Fi.
- Go to “Software” settings to check for any available updates.
- If an update is available, follow the prompts to install it safely.

3. Tire Inspection

Sub-steps:
- Check tire pressure using a digital tire pressure gauge.
- Inflate tires to the manufacturer’s recommended PSI (found on the driver’s door jamb).
- Inspect tire tread depth; replace tires if they are worn beyond safety limits.

4. Background App Management

Sub-steps:
- Access the “Apps” section from the main menu.
- Identify any non-essential apps (e.g., streaming services) and close them.
- Disable features such as “Always-On Display” if not needed.

5. Environmental Adjustments

Sub-steps:
- Adjust climate control settings to optimize battery usage (e.g., use pre-conditioning while plugged in).
- Monitor usage of heated seats and steering wheel, as these can increase battery drain.
