I feel my my battery drain is so annoying that it made me sign up just to ask. I got my iphone 6S+ Friday. Updated to 9.0.1 Since then i haven't used it except to adjust settings. Downloaded apps but did not sign in yet (FB, twitter, etc) i am currently seeing a drain of ~3% per hour while i sleep. Even during the day its about 2-3% per hour without me touching it. I have wifi on, but everything else like bluetooth, cellular data, location services, backgroundapp refresh, parallax, app store auto upgrade, fitness motion all turned off. Is this level of drainage during idle normal?
