So, with all these threads about battery life, I have been keeping a very close eye on my battery, usage and standby data. I don't use my phone much and noticed that without ever turning my phone on, from about 6:30 last night to 6:30 this morning, I have about 8 new minutes of usage- and the phone was never turned on!

I always assumed that usage meant me actually turning on and using the phone, but is it actually compiling time the phone may have spent searching for a signal or something? I do not have push or any apps turned on....

    Does the phone check for new email?

    Yes it will be background tasks that have taken place (i.e. mail polling, push notifications etc)

    Clever things

    No, I have it set to so that I check for email manually. The only things "on" right now are:

    Phone
    Mail (but NOT push)
    Contacts
    Calendar
    Notes
    Calculator
    Camera
    Safari
    Dots free
    App Store
    Barnes & Nobles App
    iPod (but not playing music)

    Nothing that I would think would be searching for signal at anytime or anything like that.

    Something has been done on the phone that the counter has determined was usage and not idle time, without knowing the actual processes running in the background (not tasks) its hard to determine

    Bluetooth? (runs as a BTServer in iPhone and may count the seconds it searches for devices)

    Did you have any alarms or phone calls or texts (even if you didn't supress /answer / read them).

    Both of these count as far as I am aware

    Yeah; I think that it has to count any time it wasn't fully asleep in standby to the usage timer...
    I doubt there is any concrete documentation available to us users for that though.
