Since I update the firmware version, I've been getting a weird error. If the heart rrate tracking is on, the watch periodically shifts into dead battery mode
despite having almost full battery. as soon as I plug it in, it comes back to life,
and immediately has a full battery
. (ie, the glitch isn't an actual rapid battery drain, just a software glitch that thinks the battery is dead even though it isn't). Anyone have any suggestions?
