I've done everything as proposed to maximize my 4S battery life but it still isn't enough. It craps out in the middle of the day, no matter if I use it or not. I lose around 20% just overnight, barely any notifications. Brightness is at 50% with auto-brightness on. Wifi is used about 75% of the time, 4G only when commuting and outside. Only 1 mail account (personal) and not that much being sent to it, maybe 10 emails per day. Texting is moderate, calls maybe 1-2 a day. Not a lot of browsing either, I use Flipboard and Quora mostly. Camera is used moderately as well. Location Services are off for apps that I don't absolutely need it for. Only Camera and Maps have LS on. Same goes for notifications. I've set the weird 'Time Zone Setting' thing off. With all of this, I still maybe get 5 hours when draining it completely. Genius bar says battery is ok. I know the battery issue has been discussed to death but there has to be a way to make this better.
