Got up this morning to find my Fenix 3 dead. Battery yesterday was about 70ish %, this morning 0%.
same for me, I think its related to poor handling of the bluetooth connections, I think if the watch goes out of range of the paired phone for a few minutes (maybe up to 20 or so), when they come back in range of each other they reconnect fine. But if they are apart for a longer period, they seem to have issues reconnecting and thats when the battery starts to drain.
Up until this point yesterday where Igot the massive drain, the battery life was much better than it had been , I was about to be impressed that they had finally managed to release a firmware that didnt seem to have any major issues.
