    Just as a test, I had my 4S on overnight without using it. Virtually everything was shut down except 3G Network and Wi-Fi. No Siri, no push, no location services...

    From a 100% charge at 9:57 pm to a 64% charge at 7:05 am...a third of the battery capacity gone with nothing happening.

    So, I'm wondering. Just what does Apple mean when it claims approximately 200 hours "stand-by" capacity for these phones? Is there a listing somewhere of what can be turned "on" during standby and what should be shut down? Because the results I got would indicate my phone battery would be dead in about 24 hours, even if I were not using the phone. :mad:

    Thanks...

    "Standby: Amount of time iPhone has been powered on since its last full charge, including the time the phone has been asleep."

    Is "asleep" the same as "stand-by"? I would guess so.

    So...my phone has been "asleep" for about nine hours and lost a third of its charge.

    So, what's with the "200 hours" claim?

    I believe Standby includes the time the phone has been both asleep and used. Or, to put it another way, Standby includes Usage but Usage does not include Standby.

    As for the 200 hour claim, Apple have themselves admitted to there being a battery drain problem with iOS 5 for some users, as evidenced by their recent release of iOS 5.0.1 to address this problem, among others. However, from reading numerous threads throughout this forum, that recent release does not appear to have addressed the problem for everyone.
