It seems Wi-Fi is keeping the device awake much more time than in previous builds.

The CPU does enter deep sleep normally, but the time of "screen off + CPU awake" when the Wi-Fi is turned on seems much longer than in the RC1.

The kernel is the same, so is the Wi-Fi driver. But there were some general changes in CyanogenMod regarding Wi-Fi, so if there is a problem it should show up in all devices.

The changes I found are the following:

Let's wait and see what unfolds...

Yup. Something's going one there.

The battery life is nearly half of what is was in RC1. Those changes don't look extensive so i doubt that's the cause.

I guess we wait and see ...

Batt normal, wifi goes to sleep as it should, no sensor problems for now. Do a clean flash or reflash by wiping cache and dalvik cache. If batt level was wiped before flashing, usually the first drain is faster.

As I said, it does sleep fine, but it wakes up much more than normal when wifi is on.

Do the test yourself with CPU Spy, clearing the stats, turning screen off and leaving in stand by, then wake it up and measure the time it was awake.

To me the time with CPU on (in any frquency) was much higher with wifi on than witb wifi off.

By the way, my installations are like surgerys, formatting boot, system, rebooting between flashes of CM and GApps, wiping data, cache and dalvik cache twice (in the beginning and the end of the procedure). And I don't use dirty or obscure apps that drain battery.
