    FWIW. My phone is on 2.0 using pwnage tool app on the mac.
    Battery life sucks..
    I haven't have the chance to find out what's going yet. One thing I notice is if I turn off exchange email then battery improved quite a bit.

    I guess, installing Cydia and running "top" but that kinda defeats the purpose

    I know that if I played games, I could drain the battery in a few hours.

    I don't think that SSH had anything to do with it but I plan to reinstall it and test again.

    My point is that don't be fast in blaiming pwn tool, 2.0 or SSH, I'm sure we're all excited in testing out 2.0 and the appstore and that could be the reason the battery drains out so fast.
    ok, nevermind, battery does suck. Question is who's to blame. I am using push email through an exchange server as well.

    if you think about it. The major difference in 2.0 fw is the exchange, cisco vpn, appstore and signed app.
    Not much app now so it's unlikely that an app can cause this. VPN, you use it when you need then you shut it down. Appstore is the same. That left you with exchange.
    I found the similar issue when I was playing with beta3.

    Did you pwn that beta? How about SSH and the like. I know it's unlikely these cause battery problems, I'm just trying to make it certain.

    I think I'll switch push to manual and see what happens.

    Yes. I did pwned that beta. Remember during the beta, there were no installer or cydia therefore no SSH at the time. It was simple and unusable at the time.

    Cool, I already turned push off and waiting to see what happens. I'll report back tomorrow...

    I agree with this. I'm starting from scratch and adding 1 item at a time. Personally, I don't think Cydia and SSH are to blame, but maybe they are.

    My iPhone has these differences vs when it was on 1.1.4:
    • Wifi via Certificate & Radius
    • Exchange (That I can only access while connected to above Wifi)
    • VPN (that connects but doesn't work )
    • New Appstore apps
    • New Cydia & SSH
    • iPhone 2.0 firmware


    Green = I've tested, and it's not the cause (for me)
    Orange = I haven't tested
    Red = I've tested, and it is the cause (for me)

    Tests
    Base
    I've went to a completely base image, with just 2.0 and TZones and it is snappy, and battery lasts a long time. So I can rule out PwnageTool and 2.0.

    Exchange & Wifi
    Tonight/Tomorrow I'm testing whether it's the wifi/exchange setup. Maybe the phone is constantly looking for the exchange server?

    Edit: My particular setup, an enterprise WPA2 Radius server with certificate based authentication, ate through the battery. The phone was fine throughout the night when it couldn't hit Exchange, so my theory of constantly looking for Exchange is incorrect. VPN Not tested because it doesn't work through my company.

    I cannot test Exchange without this Wifi, so I don't know what's causing it. In theory I could test just the Wifi, but there's no point in it for me. Others should test removing Exchange settings and seeing if it helps.

    AppStore
    Friday, I'll test the AppStore apps by downloading some, opening them, and not restarting the phone. The apps I had were Zenbe, AIM, Aurora Feint, JirboBreak, Restaurants, Yelp, Tomato, and Yes|No Free. I think this will be the culprit since there are reports that legit 3G users have problems as well.

    Edit: Ran these programs, plus installed Google and SmugShot. Didn't reboot phone. Battery life is fine - about 75% full after my usual test.

    Cydia & SSH
    On the weekend, I'll test Cydia by installing Cydia, updating it, and installing SSH. Again, go without restarting the phone.

    Edit: I ran this for two tests, fully updated as of Sunday morning. The first time, battery ran down to under 50% in 12 hours. I rebooted the phone, and the second day the battery lasted a decent amount. A little more drained than usual, but not enough to indicate that Cydia/SSH were doing something. Could be that I used my phone more, though I don't think I did. However, my phone did crash twice requiring a hard reset. Not saying Cydia is to blame, but in all the other tests I've done I haven't had my phone require a hard rest once.

    Measure
    The measure will be fully charging my phone before going to sleep, then doing the test at night (running apps then closing them), and seeing if it can make it to 5:00 the following day without hitting the 20% alert. I did this regularly on 1.1.4 and can do it now on a blank image, but couldn't do it when I had battery problems.


    If anyone wants to join in my testing or critique my methodology - feel free. I think this is as objective as I can get while still using the phone, but if there are better ideas, I'd be glad to join a community project.

    @iRobie,
    I have:
    - tzones + exchange (mail turned on) . Wifi turned off and battery sucks.
    - wifi on + exchange (mail turned on). Edge off and battery sucks.

    Note: exchange does work over tzones (push mail does work over tzones). Another note is when I use VPN (PPTP), the vpn stays on even when the autolock kicks in; before with 1.1.4, pptp session will drop when auto-lock kicks in. I have yet to try Cisco VPN ...

    I don't think exchange is constantly looking/check for the server. I don't know how the exchange works. May be there is a exchange daemon that is constantly running instead of sleeping and wake up when the mail push arrives ??

    Hey iRobie, let's coordinate to get to the bottom of this faster. Not saying that we shouldn't both run the tests to verify but let's do them in a different order.

    I've already started a test with push(exchange) set to off and cydia and ssh installed but turned off via bossprefs(which came out today). Why don't you start your tests by installing SSH and have it active? Make sure you connect at least one time and don't reboot after that.
