I have been using 3.0.1 till a few days back, and since yesterday i am using 3.1rc4. The battery drain is definitely there. It lost around 18% battery overnight, and there were no weird wakelocks in BBS and i made sure that i ended all processes before i went to sleep yesterday. From 87 percent yesterday night to 69% today morning. There is continous drain and the curve is angled and it keeps falling. this is not the default behavior of previous siyah kernels. However, The best battery life i have had is with 3.0rc3. In that kernel, the phone, in standby, hardly sucks any juice at all! I've had more than 9 hours of screen on time with that kernel and i've posted the screenshots in this thread as well. It actually feels that the phone will run till infinity when its on standby and that it will only suck juice when using the phone! that was a wonderful thing and i am back to that kernel now.
I am not criticizing, i am just stating my observations with my phone. I am on the latest CM9 right now.
I do not tweak any values and i do not undervolt. I use Siyah Kernel as is. It ROCKS! Way to GO GM!! I just hope that these battery drain issues have been fixed in the rc5. Ill flash that now and check
