Quick kernel review

i was going to participate in the kernel testing, but I am finding that my phone my throw off the overall data everyone is collecting.

The Quick and dirty. The stock kernel and the mdj 10.30 were virtually identical to me. Got great gps lock, calls were crisp, messages came and went quickly, but I could not get tethering to work. The primary problems i had were high cpu strain on virtually every process (sliding screens, placing widgets on home screens, being on the internet and having a phone call come in). While they worked it was sometimes time consuming waiting for the phone to gear up for the next process. BTW, i have posted this before, but I use SeePU to monitor the strain on my phone.

I ditched mdj's for Rafpagina 1.6. It was a bit snappier. major props for having the bluetooth controls working. I have not had that happen since my switch from window 6.5 5 months ago. I noticed that certain programs ran a bit faster (MyPod, Doubletwist [for music playback] and the internet was smoother). however, i still had a logjam leaving one program to swtich to another. I could tell this because SeePU would rung bright orange. (I would have to not press any other program until it reverted back to green status). Then i tried something new. I disabled background data. I did not want to do it but I did. I noticed an increase in speed and i was able to move from program to program with relative ease. The constant problem though was battery drain. never got a 2 or the mythical 1 that some have posted, but everyting seemed to work. I kept it for a day

Tried Rafgagina 1.7 it was almost exactly like 1.6 HOWEVER it was very sluggish when it came to downloading from the app market. so much so that I experienced TWO force closes/auto reboots. I have not had that happen with any other kernel since I switched over to the CWM version of Android. Not cool. So I switched back to 1.6. Now, The reason why I don't know if my contribution will be as valid as some others.

I am reading about battery life and the slow drains everyone else seems to be getting. I an another person seem to have erratic drains. I thought it was me, but I finally did a log of my battery history. Below is just a one hour sampling from this morning. (I don't know how to post the whole file excuse the length).

The phone was in sleep mode. the only thing I had turned on was bluetooth. Someone posted insane numbers of loosing a bar or two - an hour!?!? my phone is killing the battery (even though I did manage a 2 for thirty seconds). But this seems to be consistent in every build and every kernel I use. :mad: With normal use I think I average 4-4 1/2 (and sometimes less) hours out of the battery which is crazy. it does not matter the combination of activity. I really can't say that i can offer up apples to apples comparisons of use since my phone seems to be acting differently than everyone else.

For me, right now, I am sticking with Raf 1.6
