Since charging my watch last Friday, it has remained at 100% battery.
Switched the watch off and back on again! So simple but I hadn't thought about doing that. (Press and hold top left button on mine)
It happened to me too, I restarted and showed fair value afterwards.
How did you fix this?
My 955 is stuck on 100% for more then 24 hours now. Reboot didn't work
That didn't fix mine but I put it in the charger charger and then afterwards it seem to work properly again. Not sure what was going on though.
