After 48 h: From 100% to 90%! Firmware-Version 20.0, Fenix 5x, no third part Apps or Widgets!. Seconds are displayed in my Watchface. It is my third Fenix 5x and I had never had problems with the battery life. On the two first units, I had problems with the USB-Connectot (pin 3!). But now, it seems tha tthe problem has been fixed!
Garmin 5s plus - As I thought, one of these things helped: Changing watch face to simple garmin Manually updating 5s + to 12.71 beta Switching usb protocol from mtp to garmin Turning the watch off and on briefly, right after it completes syncing activity to the Garmin connect app After battery draining up to 100% daily, it seems fine now.On my 2 weeks old f5s I can see, from the beginning, what I consider as twice the expected battery loss during GPS (and swimming) activities : 20% per hour for GPS, 10% per hour while swimming (without GPS). OTOH I don't experience such huge battery drain during the night, neither during day. My f5s lost 3,5% last night in 7 hours, and it's Actually when I woke up the watch is abnormally hot. During that daytime the battery drained 20% more. I have tried to restart and reset default setting in the watch but the battery still drains very fast after full charge. 15% drain per day without any activity tracking. 10% more with just 1hr GPS running. . 50 210 116 201 204 308 319 192 4
