    I noticed that while the phone is charging, it never drops to 0 % CPU usage, so no deep sleep. I searched for an answer but none of them were about S2.
    Is this a normal occurrence in the Android OS or the S2 ?

    Its normal mate. :D

    Deep sleep doesn't occur while charging. CPU is at 200 MHz at this time. :)

    I don't know the reason why though...

    The CPU works as charging controller, eg. controls that the battery temperature remains in its charging operating range.

    The Li-Ion battery's temperature operating range is:
    for discharging -20C (-4F) to +60C (+140F).
    for charging 0C (+32F) to +45C (+113F).

    The battery won't be charged if its temperature is below 0C (+32F) or above +45C (+113F) because the phone's charge controlling will project the battery.
    Therefore it'll shut down charging until the battery's temperature will meet again the charge operating range.
