Ever since I updated my iPhone to 7.1 yesterday, I seem to have a large amount of battery drain. I'm losing about 3 percent of battery an hour, and that's if the phone is just sitting there, locked. I've checked all of my settings, and everything is exactly the same as it was before I updated. Is anyone else having batter issues since updating? I just charged my phone 2 hours ago, and it's already down to 93 percent, with barely any usage. Which is another issue, I've used the phone for maybe 10 minutes since I last charged it, but in settings, under usage, it says I've been using it for over an hour. I checked in the app switcher, and none of my apps are open. Anyone have any ideas?
