I always tell myself to write down what jailbreak apps I update and when but I never do it. I just updated a bunch of jailbreak apps and now my battery life is going to ****. I had a similar problem when i was on iOS7 but the battery issue went away when I updated to iOS8. Never found out what app was causing it. Now it's back. Anyone know of a certain app known to cause big battery drain issues? I use to be able to go all day on a charge with moderate to heavy use, now the battery drains pretty quick when the phone is locked.
