Unexplained battery usage

Hi I've just gotten the Samsung Active watch in 40 mm, but I'm struggling with the battery. Maybe it is this terrible, but my friend has one and gets two days of use. I have turned off AOD and location, set brightness to 3, installed a Samsung watch face and I'm still experiencing so much battery drain.

 

When I go for a run, the battery drains about 1% a minute, which is pretty unacceptable because that means it won't last long rungs. Today I only used it for text notifications and in 10 hours it went from 100% to 60%. When I check the watch info, the percantages only add up to 31% and not the 40% the watch shows losing. I don't know why that doesn't match up. Do I have a defective watch or is the battery life just that poor?a
