First let me thank all of you, Im glad to have some back and forth conversation on this matter. What I am displaying in the OP is that there is some sort of wake lock before wifi is turned off when screen is off, so if you are constantly turning your screen on to view the time, or look at the home screen (anything really that dosnt involve pulling data) while wifi is on, you will use more battery; This may be ICS related, if anything its leak related, since our cm9 uses the leaked kernels.
And thanks John, Im sure the source will fix this if they dont have it fixed at the time of OTA.
@studdmufin, I hope you can see what Im trying to say, as Im not saying one way or the other that wifi/3g is better in standby for times when the phone is idle more than the time it takes for the "turn wifi off when screen off" kicks in; Im only saying that it keeps the phone awake 40% longer in that 10 minute window, so this will harm battery life.
@cnstarz, 10 minutes is a perfect time frame in this case, I think the reason why has been explained in this post.
