So, my iPhone 5s has 7.1.2 on it but it is jailbroken. I feel like the JB might be wearing down my battery a bit so I'm considering a fresh restore to iOS 8.1.2. However, I've seen online many posts and articles about how terrible the battery is for this particular device with iOS 8.1.2, these posts are somewhat dated to early stages of release. After plenty of charge cycles, usage, and tweaking of the settings, how do you find your iPhone 5s battery is performing now with iOS 8.1.2?
