Model number SM-R770 Tizen version 184.108.40.206 Software version R770XXU2CRH1 How many days/hours do you get from a full charge? Was 3+ days, now <1 day How long have you had the watch? 10 mo Do you use Always On screen? no Do you leave Location/GPS on? no Do you leave WiFi on? auto Any comments/observations related to battery levels and usage - I noticed my battery was draining suddenly a few days ago. Last night I went to bed after charging it earlier in the day and it was at >90%, and when I woke up it suggested I should switch to battery saver mode since it was at <15%. I tried switching and while it was doing that it died. I do not know why but this is the 3rd day in a row this has happened and I am very frusterated. This had been a great watch up until now, very low maintenance yet handy and useful, but this problem is making me wonder if I will ever get a Samsung smart watch again.
