Battery rundown with iOS 8.3 on iPhone 4S
uupgraded to iOS 8.3 last week, and have been having horrible battery life since then. The phone drained between 10p-6a from a full charge; with iOS 8.2, it lost 20% in the same spot overnight. I've turned off background update, iCloud Keychain, all the other stuff cited online ... most ominously, when I check Usage I see just a spinning wheel, no percentage stats. Dearest phone, why won't you tell me how you've been partying all night long?
if anyone's found a fix, please let me know. Apple, if you're listening, please update this so I (ahem) don't need to run out and buy a iPhone 6.
