So, Garmin's stated battery life numbers are with their minimalistic watch faces -- which is fair enough. When I was EVALUATING the ENDURO, before I bought it, yesterday, I had seen 44-day battery life.
But, now that I am using it as my MAIN watch -- & set it up as I like, with ActiFace, a bunch of widgets & 60% brightness (all the time) -- BEST I can get is 30-day battery life. That is OK.
I do 2-hours of GPS every day. I am losing 3-days of battery life each day.
So, I guess my MAX battery life will be about 10-days -- with these 'settings'.
I also have a feeling that it is overcounting STEPS by a LITTLE. Not much, but definitely overcounting.
I am also having trouble with ALL my alerts -- activity & goal alerts.
Other than that it is OK. Thanks. SMILE.
