Ever since CM moved to 4.2.2 I've been experiencing very poor battery life out of my Toroplus.  I have tried multiple nightly, M snap shots, complete wipes, new battery, and same result.  Any ideas on what to try next?  I'm currently running the nightly from 9/8, with the included kernel.  This last week I added the extended battery as well.  Here are the links to my screenshots from today.

Screen on time was only 18 minutes and it was my highest usage of battery???

Try a different kernel. I am getting great battery life from Tiny Kernel default settings.

Have a look at the battery thread in the FAQs subforum as that should be able to help you narrow down what is causing the drain.

On the Toro, I noticed 4.3 was having a higher than normal battery drain, and used wakelock detector overnight  and discovered it was the Facebook app and the Facebook Messenger app that were the top culprits for waking the phone up to get the current location or whatever it was doing.  I turned on the CM privacy guard on those two apps, and I have been having very good best battery life since.   I also strictly only use the Interactive Governor with the Deadline scheduler.  Some of the other combinations either drain my battery more or don't perform as well.  Hope that helps.
