I've been running SHO ver 2.6 for the last two days to see if my suspicions were correct and they are.. With both ROMs (2.6 & 3.4) wifi is draining my battery by a1/3 to almost double more then when it's off.. I used Best Battery Stats as my reference, both days(swapping times I let wifi run) I would only use 25% in a 8 hour span with wifi off but with it on I used up almost 40% in 8 hours.
During this time I never had any apps run wild and eat up battery so the only explanation I can come up with is my particular GS2 doesn't do as well as others letting wifi run all the time..
Previously tried a few different app killers and monitors but they ended up using up battery as much as they tried to save so they were nothing more then a trade off..
Guess it's just one of those "who knows why" things with my particular phone & routers..
That said I think it's time to flash back to 3.4 and put the wifi toggle switch back to work
