The battery of my watch seems to drain weirdly suddenly (had it since april). 12 days ago it was around 65% in the morning, then I biked to work (15 mins), and saw at the end of it that the watch gave 0% battery. Hadn't seen that before. It died after a few hours.
After I fully charged the battery, and it worked until I had to charge it an hour ago. I put it on the laptop at 12%, checked on in after 20 mins, still 12%, and a few mins later it went to 0% again. Switched to charging from a plug, it seems to be charging fine now.
Anyone else experienced something like this? Still in warranty, doubting if I should send it already or after another weird incident.
