I have a AT&T 3G Gear S2 and all of a sudden (the last week or so) my battery life as dropped a lot. I could go a day and a half almost two before it needs to be charged. Now after only 7 hours, I am getting a low battery warning and I have to switch to battery saving mode... As anybody else had a problem like this recently? I turned off heart rate tracking and all of the exercise notifications. Is there a way to check if any background apps are running so I can turn them off?
