When I first got the Watch I was burning through power very quickly, in one day, but that was expected, however, after settling down in daily usage I'm less impressed with the battery. I have to charge it on a daily basis, and I'm not even a power user.
Over night, I'm a late sleeper, 1am to 7am it looses at least 10%, I sleep with it on for sleep tracking.
During the day I experimented with always on display, and I had about 30% at the end of the day, now with it off it is parhaps 50% - either way, I have to charge the watch every day . I am extremely disappointed wit it to be quite honest, either that, or I have a faulty one?
I haven't even tried the power saving function, if I wanted that I would have bought myself a casio with an LCD display that lasts a year!
This is my 1st smart watch, I am seriously considering returning it and going back to my Seiko Kinetic that never needs a battery and I can see the time with a quick glance - quite irritated that I have to consciously turn and lift the watch and wait a fraction of a second to see what the time it. The Samsung I thought had come of age, but if I have to turn everything off in order to get a good battery life, then what is the point of a smart watch?
I honestly can't understand how some of you are getting 3 days use with Always On - something isn't right here...
