I have an Iphone 5 with the 6.1.3 software. This week about 5 of my apps had an update. Since the update i noticed that my iphone's battery life has been horrible. It takes twice as long to charge and it drains twice as fast. I have my setting for brightness turned all the way down, push notifications turned off, and pretty much i have to manually update everything on my iphone. I had these setting for a while now and all of a sudden my battery life stinks. Any ideas?
