I have the same issue, high battery drain since firmware update early December, reset watch with hard reset now six times, all software up to date no wifi, minimum notifications. gone from 4 days battery to less than a day very frustrating. Just had a new update which I hope would solve, but still having same battery drain I dnt even get a full day on low power mode its rediculous. This is still an issue - reset doesnt fix problem. Just using standard stock software
Guys i dont understand something. i have watch Gear S3 with Tizen 4.0.0.4 i suffered a lot fast energy drain ( worked about 7 hours) , changed battery - no difference, restarted at least 4 times - no difference, removed and instaled app in my phone - no change finally i bought a new watch ( Galaxy Watch ) - first 2 months it could work about 2 days on batteries, than less than 1 day. i stopped using my old Gear S3 for about 6 months. One time- for no reason i recharged watch and turned it on- without cell connection - not wearing on hand. It worhed more than week. So i made test reset it again, recharged connected again to application- with pulse measuement every 10 minutes( like earlier) . AND FOR SOME REASON IT STARTRE WORKING CORRECTLY - with the same system like earler- nothing changed, with error reporting pulse m,easurment every 10 min- aand constant connection to phone now it works more that 3 days !!! W_TF? the ONLY difference was that now i am using ONLY one of oryginnal clock wallpapers - earlier i used downloaded custom one which looks like MS DOS screen. i dont understand there this change was from.? please share your experience
