It does look like it's a problem with the 4.0.4 modems. The gs2 has just received the update and someone has reported the high cell standby reading after flashing the modem from the firmware.

My battery life has been awful with my gs3. Only getting half a days life out of the battery. Last few days out had a full 8hours charge and was only used for a few messages and 15min of spotify on my commute in to work. The rest if the day it laid at rest until 1:30 pm when it signaled low battery! Battery menu showed that 65% was used by standby ! Only 20% was used by the screen.
Thats right. Its not being drained. Just mis-reporting what is using the battery.
Yes. I reported it to them. Told them what information was incorrect (*and where) and linked them to this petition.
