Step-by-Step Solution
Install fresh battery set and verify fit
Use the exact battery type recommended by August and ensure proper seating, because contact instability and mixed cells are common hidden drain causes.
Check lock calibration and door alignment load
Recalibrate the lock and test resistance through full bolt travel, since binding against the strike plate forces motor overwork and short battery life.
Audit bridge/WiFi signal and reconnect frequency
Confirm stable connectivity path and avoid weak-signal locations, because repeated reconnect attempts can consume significant battery on smart locks.
Review automation volume and unlock retries
Reduce excessive automation triggers and repeated command retries, because frequent wake events increase daily power draw more than expected.
Compare drain rate over one full week
After tuning alignment and connectivity, track percentage drop over seven days to verify improvement before considering hardware replacement.
