Battery spontaneously discharging?
I have had it happen a few times now that my multisport cardio watch has spontaneously lost power after less than 1 hour of activity after fully charging. I am not sure if it is to do with cold or wet weather. But the only way of getting the watch to work okay again is to charge it for a day or so. When I only charged it for a few hours it discharged immediately again after starting recording.
Has anybody else experienced this? Any suggestions on how to fix or avoid it?
Thank you very much for any help!
