Apple iPhone 4S

Sorry, but I always did all of those things & still had the same problems with every one of my Android phones. On my iPhone I do have the auto brightness off, but I don't have to worry about whats running in the background. Sorry if this sounds rude, I don't mean it to be, but I hate when everyone says you need to do this or you need to do that to your Android phone. I shouldn't have to run through hoops to get a phone to work. Just my opinion. I know lots of people that love there Android phones & that's great. I'm just stating my experience with Android & IOS & I find IOS to be a lot smoother.
