I have been investigating the sleep issue that many of us are facing and I think I may be on to the root cause of at least some of the wake ups. It seems that the problem appears when background sync is enabled and disappears when it is off.

To test, I have been using the quick sync settings app to toggle background data on an off. There should be a hook in the OS to enable and disable this service on a sleep event trigger (sleep switch press). I hope to have a good understanding of the subsystem and can perhaps edit the suspend / sleep function to switch it on and off with the event trigger soon.

Can others test sleeping with background data off?

It really is a pain. I paused this test to test removing the telephonyprovider.apk removal. It also woke up a few times especially with WIFI, but then it seems to have slept all night which it hasn't done before.

I'll be testing removal of the telephonyprovider.apk + no background data tonight overnight.
