At a Tesla Service Center this typically costs **$0 - $200 (Settings advice free; diagnosis if a fault is found)**. An independent shop charges about **$0 - $150 (Diagnosis only if drain stays high)**, and doing it yourself costs **$0 (Settings changes)** — potential savings of **Up to 100%**. DIY difficulty: easy (15 - 30 Minutes). ![Phantom Drain: Battery Losing Range While Parked](https://evfixguide.com/assets/images/battery-bench.jpg) ## Symptoms - Several percent of battery lost overnight while parked and unplugged - Range drops faster in very hot or very cold weather while parked - The car rarely goes to sleep (third-party apps or features keep it awake) ## Repair cost: Tesla vs independent shop vs DIY | Option | Typical cost (USD) | | --- | --- | | Tesla Service Center | $0 - $200 (Settings advice free; diagnosis if a fault is found) | | Independent shop | $0 - $150 (Diagnosis only if drain stays high) | | DIY | $0 (Settings changes) | | Potential savings | Up to 100% | Ranges are US estimates compiled from owner reports and shop quotes; prices vary by region, model year and parts availability.

If drain stays high with every power-hungry feature turned off, Tesla Service or an independent EV shop should check for a module that keeps the car awake. [Get matched with an independent shop →](https://evfixguide.com/?shop=phantom-drain-parked#find-shop-section) ## How to fix it yourself (easy, 15 - 30 Minutes) Turn off or limit the features that keep the car awake (Sentry Mode, Cabin Overheat Protection, frequent app polling), then measure drain again over a night or two. ### Tools you need - Tesla app (to check battery percentage before and after parking) ### Steps 1. Note the battery percentage when you park and again the next morning to get a baseline. 2. Turn off Sentry Mode when you do not need it, or use its option to exclude Home, Work, or Favorite locations. Sentry Mode keeps the car awake and is the most common cause of high drain. 3. Turn off Cabin Overheat Protection, or set it to fan-only instead of A/C, if you do not need it. 4. Disconnect or reduce polling for third-party apps and services that read data from the car, since frequent requests can stop the car from sleeping. 5. Avoid opening the Tesla app repeatedly while parked; each check can wake the car briefly. 6. Remove scheduled preconditioning you no longer use. 7. Measure overnight drain again with these changes. If it is still high with everything off, book a service diagnosis. **Pro tip:** Some loss while parked is normal, and more is expected in extreme temperatures as the car protects the battery. When parking for a long time, leave the car plugged in if possible, with the charge limit set to your normal daily level. ## Frequently asked questions ### How much does it cost to fix phantom battery drain on a Tesla?
