    Default Battery Life?

    My battery life has been much worse. I have to charge it several times during the day, either through the car charger or with the computer.

    Default Shutting Down when < 40?

    After installing iOS4, my 3Gs started shutting down when the battery level falls below 40%. After charging for awhile it does come back on again and displays a battery level in the 40% range. Anyone else experiencing this?

    tony, not exactly, but mine died last night (it had gone down to 0%, I was away from a charger) and when I plugged it in, it did jump to 50% after only a few minutes of charging.

    And follow up from my post on the previous page, I think I identified which app's update was causing my battery to drain: Dogbook, which I'd downloaded early this year to post pics of a stray I picked up and not used since. Deleted it this morning, and it has drained at a normal rate today when not in use.

    I can't be certain, but I assume it's apps using the new ios4 features (multitasking?) that's causing the problem. Odd thing, when you go into app organization mode (tap and hold an app), it's supposed to let you turn on/off apps running in background mode, but there wasn't such an icon on dogbook; I didn't check skype, as I didn't know about this feature yet at the time.

    :edit: This is all just strange, it's possible something else is going on entirely and I'm reading into coincidences around the timing of it. But something's definitely hinky since I installed ios 4.

    :edit2: Aha! I was misinformed, to turn off background tasks you have to tap and hold in the quick switch drawer (double-tap home button). re-downloaded it to check and Dogbook is indeed running in the background.
