After a week of use of the FR245M I’m experiencing battery life way below the claimed 6/7 days in smartwatch mode.
Currently a full charge with no recorded activities, no music playback and observing some of Garmin’s battery saving advice such as using a watch face with no moving seconds and turning off pulse Ox and notifications is getting me just under 48 hours before running down to 0%.
I am still using the heart rate /sleep monitoring etc but I consider these to be normal metrics for smart watch mode.
Am I missing something here? Is Garmin’s claim for 7 day battery life based on operating in ‘basic watch’ mode only with all monitoring turned off or have I bought a dud?
