(Not sure if this is in the right place as it may apply to all iOS versions but this has only happened to me in iOS 7.) Hi guys, I've been running iOS 7 since the first beta (As a non-developer. Don't give me the usual stuff, I know the consequences. I know it could go wrong. I know how to go back.) and all the betas have been running great but I experienced a battery issue on my iPhone which could coincide with the recent developer site going down but I'm not sure. Only recently I discovered my battery deplete really quickly, probably about 6% an hour on standby. I then noticed my usage time was the exact same as standby time. After going through the diagnostic logs, one entry kept showing up in the Low Battery log constantly, it was this; "identityservices: com.apple.persistentconnection[identityservicesd,1713,com.apple.identityservices.registration-hbi-PendingSimpleTimer(0x1466f850)] NoIdleSleepAssertion == 255, held for 00:00:00" With a couple of code variations. (ie. 1713 was sometimes 55, the code in brackets was always different) I googled everything. Then I saw a page about the same error "[identityservicesd,55]" and there was a few things but the one that was there all the time was related to ACAccountStore, Error 6, Invalid credentials. I then went through my iPhone and signed out and back into all different accounts. Facebook, Twitter, App Store, etc, and today, its been 11 hours and only dropped 3% (Standby with Facebook notifications in the background). As a non-dev, I'm not sure it was related, but it does seem to have fixed it. Before anyone says its a pointless thread, it could help someone. I'd like it to help someone.
