Intersting, I posted this over on XDA:
Just received an update for my Gear Fit 2 today. and the battery is about to die after less than 6 hours of usage other than overnight sleep. And by usage, I mean strapped to my wrist as I drove to work, walked up 2 flights of stairs, and sat at desk for a few hours. Typically I wear the device for about 14-16 hours a day, throw it on the charger for about an hour and a half before I go to bed to top it off (usually about 70% or so when I put it on the charger). It will have 100% charge when I go to bed, and in the morning will be around 97% or so, falling to around 70% by about 22:00.
Has anyone else received this update and had any battery issues? I realize the update process would have likely used a few %, but my Fit2 is literally at 8% and it's not even noon yet. I was shocked when I got the alert to turn on power saving. Hoping this is an isolated glitch and will be OK tomorrow after I charge this bad boy back up.
As a follow-up, in a half hour, while on power saving, it went from 8% to 0 and shut off.
