Are we sure CM10 is the god rom? I was running something called paranoidandroid 2.15 which is a built over CM10 and it was piff. But had my battery
Also brehs do any of ya"ll mess with Tasker? I have had it for awhile and its a bit to involved.
There's a reason they mostly all build over CM10's gawdly work. Not sure what phone you have but after switching to CM10 my battery been on god mode on my Nexus.

Before on stock Sprint rom my phone would die within 10 hours barely using the shyt. Think something with stock rom kept it from deep sleeping.
