I have had my Gear S for a few months now. My battery life has always varied wildly even though my use of the watch is pretty consistent. Sometimes I would have 65% at the end of day and others would be nearly dead but it always lasted a full day. In the past couple of weeks, the life has gotten much worse but it only seems affected when I am at work. This past weekend, I used my watch for several texts, a phone call or two, a 45 minute run with GPS and still made it through a full day with about 30% remaining. Today at work, it went from 100% to totally dead in 3 hours! WTF? I did not even use the watch for anything other than checking the time during those 3 hours. I did update something in Gear Manager last night hoping it would improve batter life as it was already dying in less than 8 hours when I am at work (not even using the watch). I do go in out of BT range from the phone when at work probably 10-20 times a day. The phone stays in my office and is connected to the office wi-fi. I'm not sure what's going on but my watch is useless if it will only run for 3 hours. Please note that I don't think there is anything wrong with the battery as on the weekends it stays charged all day. Help!!!
