How much Tesla battery does scheduling Sentry Mode actually save?
Battery savings from scheduling scale roughly linearly with the number of hours Sentry Mode is turned off.
Tesla publishes no power figure for Sentry Mode. Independent tests and owner logs mostly land between about 130 W and 250 W, roughly 3–6 kWh per day if it runs around the clock. The numbers below are an illustrative calculation at 225 W, the average in Enhauto’s measured overnight Model 3 test, on an assumed 75 kWh usable pack and ~250 Wh/mi. Your car will differ, so measure your own drain.
Per-hour impact
Each hour Sentry Mode is off instead of running saves approximately:
- ~225 Wh of energy (130–250 Wh across the range above)
- ~0.9 miles of range
- ~0.3% of pack on a 75 kWh battery
Realistic daily savings
| Hours Sentry Mode is off | Energy saved | Range saved | Pack saved (75 kWh) |
|---|---|---|---|
| 8 hours | ~1.8 kWh | ~7 mi | ~2.4% |
| 10 hours | ~2.25 kWh | ~9 mi | ~3.0% |
| 14 hours | ~3.15 kWh | ~13 mi | ~4.2% |
At this rate, a 10-hour daily off-window adds up to roughly 820 kWh and ~3,300 miles of range per year (2.25 kWh × 365).
