    I turn off my phone then plug in the wall charger. After a couple seconds i get the battery icon with moving dots indicating charging. Then a few seconds more the phone turns on.

    Can I charge with phone off?

    Is there a setting I need to change? I tried turning all settings off like sync, wifi, GPS, BT etc. thinking there may be some auto wake feature.

    I recently rooted using this method on galaxy s 2 root dot com

    Unfortunately, I didn't try charging with phone off before rooting. So I'm wondering if this is the cause or it is normal behavior for ATT SGS2.

    Any help would be appreciated.

    Thanks

    Not sure if it's normal or not as I've never tried to charge my phone when it's off. I do know that if it's in standby it does power up when the charger is plugged in. I just hit the power button to put it back into standby.

    I'm kinda leaning towards it's normal for it to power on possibly for power management purposes.

    If i charge the phone after turning it completely off, it stays off. Are you sure you're hitting the second power off pop-up window? I'm thinking that maybe it's in standby and not completely powered down.

    I am having the same issue. Originally the phone would charge in a powered off state and just the green battery would show up briefly...when fully charged it would pop back up indicating so. Now, as soon as I plug in the wall charger or the USB to the computer, it reboots and powers on. All I have done is enable the on-board battery saver. I would prefer to charge it overnight in a powered off state so I don't get notifications...I could put it on silent, but it should charge while off. If I shut it down while charging, it immediately reboots.

    Update: my post should have been in the T-Mobile forum. At any rate when I turned off the battery saver the phone went back to its original behavior.

    This is the result of using zedomax's rather crappy (and unmaintained) kernel. Specifically, it happens when the kernel developer enables the "interactive" CPU frequency governor.

    This will not happen on any stock kernel, nor will it happen on any of my releases except for two from late November.

    I had the same problem and turning off the power saving mode under settings fixed it too.

    Plug into the charger before turning off it may not look like its chartering but it but it actually is charging
