1. Auxiliary 12V battery maintenance: Wakes every 10-60 minutes
If you notice your Tesla waking up on an exact pattern, this is the reason why.
According to Tesla, these wakes are to support the auxiliary 12V battery system.
In certain conditions, this may be triggered by the Tesla data API. In Tessie, change Settings > Connectivity > Polling Interval to 60 seconds and wait 24 hours to see if it helps.
If it doesn't help, many customers have had success in reducing excessive wakes by getting the 12V battery serviced or replaced.
2. Background uploads: Wakes every 2-15 minutes
When data sharing is enabled, the vehicle may frequently wake and upload data to Tesla in the background.
You can prevent these wakes by disabling Software > Data Sharing in the vehicle.
3. Tesla check-ins: Brief wakes every 3 to 24 hours
Tesla is constantly deploying configuration changes, alerts and updates across the fleet, so your vehicle will periodically wake up and check in with Tesla. This is known as "phoning home" to the Tesla Mothership.
These wakes can't be prevented.
4. Background downloads: Occasional prolonged wakes
Software updates can download in the background and keep the vehicle awake. Some software updates will only download on Wi-Fi, but others will also download on cellular data.
These wakes can't be prevented.
5. Pending software updates: Occasional prolonged wakes
If a software update is pending install, the vehicle may stay awake or wake repeatedly until it's installed.
You can prevent these wakes by installing any pending update.
