So, I jinxed myself with the last post, after almost 2 years with no problems, I didn't have to reset, gps failed only once or twice, it looks that coupe of days after my post, my watch sensors failed, after couple of resets and subsequent failures, even after resets, sensors wouldn't want to start working... so I factory reseted it, waited for a day, connect it to phone and immediately turned bluettoth and wifi off, and since then it started to work fine... so there is something fishy with what samsung is doing to the watch probably through s health. I have 100k race in 8 days and I'm thinking of buying garmin watch now... Actually I did a mistake and updated the watch cca 3 weeks ago. Because of the race, before the update watch would stop activity if put to charger, after the update activity woudln't be stopped when connected to charger so I could do with 10 hours of more accurate gps. before that, I did 8 and a quarter hour race and my watch was below 15% when I got back to my car afterwards. So probably it wouldn't last throughout my whole 100k race without charging
