Tesla is rolling out a small but meaningful update for Summon, aimed at reducing Summon Standby’s unnecessary energy usage when the feature is least likely to be used. First spotted by the folks over at Not a Tesla App, the changes ship with software version 2025.32.
Summon Standby keeps a Tesla’s FSD computer partially awake so owners can quickly activate Summon through the Tesla app. While convenient, the feature comes at a cost — keeping the car awake results in phantom battery drain.
With update 2025.32, Tesla is optimizing how Summon Standby works by introducing two new conditions that automatically disable it to conserve energy.
The first is overnight. Between midnight and 6 a.m., Summon Standby is now automatically paused, a time window Tesla’s data suggests sees very little usage. The second is long-term parking: if a vehicle remains parked for over 24 hours, Summon Standby will be turned off until the car is driven again.
For owners, the trade-off is minimal. If you try to use Summon during one of these pauses, your Tesla will simply take a few extra seconds to wake up before responding. In exchange, the car avoids wasting energy when the feature is unlikely to be used.
Summon Standby debuted around this time last year alongside Actually Smart Summon (ASS), and Tesla has been refining the Summon feature ever since. Software version 2025.32.3 also introduces another power-saving feature, called Low Power Mode. That mode disables high-drain features like Smart Summon, Sentry Mode, and Cabin Overheat Protection when activated, giving owners another way to curb phantom drain.
Taken together, these updates reflect Tesla’s ongoing effort to fine-tune vehicle software in ways that improve efficiency with little impact on user convenience. Across the global fleet, optimizations like these could add up to major energy savings, reducing costs for owners and lessening the load on the electrical grid.
