Cell standby seems to be

1) A modem firmware failure for those who actually have bad cell standby battery life. This seems to be caused by not entering low power mode on non active connections or switching to fast/often between the power modes.

2) The batteryprofiles.xml populates the cell idle entry with 33mA as power drain as opposed to 3mA for the S2 which has the older version of same type of hardware modem. This is absolutely retarded as the actual drain is not really that much and being reported much higher than it is.

I personally am running on 2G which is more than enough for chat, email and notifications and switch to 3G whenever I need to manually or am on Wifi. I am still on my first charge since I have gotten the phone, and I'm at around 40 hours lifetime with 4H screen time with 33% battery left. This is with around 20 reboots while flashing and testing my kernel, and playing with the phone. Over-night (8+ hours) I lose about 3%.
