Why Is My Tesla Battery Draining So Fast?

by Phil Borges // in Car

If you have noticed that your Tesla’s battery is draining too quickly, there are a few things you can do to stop it. First, make sure that you are not leaving any power-hungry features on, such as the air conditioning or heating, while the car is parked. Next, check the settings in your Tesla’s app to see if any features are draining the battery. You can also disable any unnecessary features to conserve battery life. Finally, make sure that you are charging your Tesla regularly and not letting it sit for too long without charging.

How Long Should a Tesla Battery Last?

Tesla batteries are designed to last for several years, and the company offers a warranty that covers the battery for up to eight years or 150,000 miles, whichever comes first. However, the lifespan of a Tesla battery can vary depending on various factors, such as the frequency of charging, the temperature at which the battery is stored, and the age of the battery.

Why Is My Battery Suddenly Draining So Fast?

There could be several reasons why your Tesla battery is suddenly draining faster than usual. One common culprit is a software update that has not installed correctly, causing the car to use more power than normal. Another reason could be that you have recently enabled a power-hungry feature, such as Sentry Mode or the cabin overheat protection. It’s also possible that your battery is simply getting old and starting to lose its capacity.

How Much Charge Does a Tesla Lose When Parked?

When parked, a Tesla can lose up to 1% of its battery charge per day. This rate can vary depending on several factors, such as the temperature and the age of the battery. To prevent excessive battery drain when parked, it’s important to make sure that your Tesla is not left with any power-hungry features enabled and that it is plugged in and charging whenever possible. You can also set the car’s energy-saving mode to reduce the amount of power it uses when parked.


Fast battery drain on a Tesla can be caused by several factors, including software updates, power-hungry features, and old age. However, by taking proactive steps to conserve battery life, such as disabling unnecessary features, charging regularly, and keeping the car plugged in whenever possible, you can help ensure that your Tesla’s battery lasts as long as possible. If you are still experiencing issues with battery drain, consider reaching out to Tesla’s customer support team for further assistance.
