There has not been a firmware update for this device since June so there is most likely another factor. I would recommend reviewing the article Tips to Extend the Battery Life on a Garmin Fitness Watch and review the settings. Especially any app installed from Connect IQ. It that doesn't improve battery life again please reach out to Garmin Support for assistance
I did a hard reset to clear off everything. And the only app I have reinstalled back are Garmin apps Hydration and Calculator. Nothing else. Still the same battery drain issue.
Perhaps that's about the lifespan of a 2 year old venu SQ2 ??? Which sucks!!!
However since the June major update, there have been a couple of minor updates. I recall a BLE Software update. Another I can't remember. These minor updates could have messed things up.
