Model number SM-R760 Tizen version 22.214.171.124 Software version R760XXU2CRH1 How many days/hours do you get from a full charge? Was 2.5 days, now 20 hours How long have you had the watch? 4 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 Up until recently, I've gotten about 2.5 days and really only use it for notifications (about 25 a day, fairly light use).
