Turn off background app refresh, that's a total battery hog especially for twitter and Facebook etc.
It's been off since I downloaded iOS 7 last year
Damn that sucks man. Are you going to get another iPhone? Or you going to wait to see what the battery is like? I would be turned off tbh if the battery continues to be that poor.
I plan to get whatever phone Apple announces tomorrow. I'm actually on 1 year phone plans. I should have just replaced my iPhone 5 with a 5S last year. Lesson learned. I think age has deteriorated the battery since it's almost 2 years old, coupled with iOS being crap
