Hi @kcrane. It is normal for Tesla’s to lose about 1-2% in charge level every 24 hours. If sentry mode is on, you can expect to lose around 1 mile per hour.
However, you may realise you are losing more than that even if sentry mode is off. This is due to the way our system communicates - it keeps polling the car to keep it awake, to ensure the connection is always active and you are able to lock/unlock without any delays.
We have built in the option for you to disable this, called “Sleep Mode”. By default, our Sleep Mode is turned off, meaning our system will constantly poll your car to keep it awake. You have the option to turn Sleep Mode on. This will save your Model 3’s battery, but it may take a bit longer (about 20 secs) for your Evezy app to connect to the car. You can also schedule it according to when you drive the car, so for example have it off during the day and on at night.
You can access Sleep Mode settings here, or go to our website, log in, and find it under the “My Account” menu. Feel free to change this setting as often as you want!
