7 hrs GPS out of 20 advertised = 35%
7 days watch mode out of 12 advertised = 58%
Total = 93%
If you are ending the week at 25%, it seems you are actually doing better than advertised.
Extreme battery saver (watch mode):
-No GPS
-No bluetooth
-No WIFI
-Watchface (https://apps.garmin.com/en-CA/apps/0...f-151280591dbf) updating at the minute....
-No button pressed everyday except alarm stop at the morning.
-Backlight minimum setting.
I can squeeze out ~3.5-4% per day on 7.10
I would rather charge mine two or three days earlier and able to use it
