what is eating my battery life? Upon restore, I noticed standby battery life was bad over the day (no usage). Turns out some "malicious" apps like Facebook turned its background app refresh on again. I disabled almost all the background app refresh (to the state which my iPad Air 2 had) and today this is what happens. Notice there's no app usage cos I didn't used the iPad the whole day but something is running, using up 6 hours of my usage time and 7% battery. Any ideas, folks?
