at last, i dont have batt drain issue. yeah!!

really? try boot it up and check under settings > about phone >
if you see "2.6.32.9-perf root@mar #3" , then you're definitely not in original kernel

i think we couldnt have usb mount in recovery bcos of this

Doesnt support new LUN file from ICS USB Gadget

my issue about batt drain has disappeared. you still have this issue?

I'm still using aire's original kernel though. haven't tried yours. Btw, what's the differences between Touch version and DoomRec version? What do you use now? does the different ramdisks have any differences?

Update: After testing yours, the device is still awake unless Wifi hotspot is removed before turning off wifi. I know and acknowledge that battery drain might be not as bad as before, but it is because of aire's kernel UV feature. the devices still awake though, so the saving isn't as good as full sleep mode.

This is how i prove the device still awake or not:
1. Install BetterBatteryStats app on xda, setup the application with iridaki's guide here
2. Reboot the phone to clear the graph on BetterBatteryStats app
3. Turn on wifi, and login to your AP
4. Do browsing etc
5. Turn off wifi after a while
6. Open your BetterBattryStats app, look at Others menu with since unplugged option. Remember both Awakes time value and Screen On value
7. Turn off your display now, wait for 5 minutes
8. Turn it on again and watch for the Awakes bar. If it stretched for about 5 minutes than before, than your device is still awake.

Touch Rec not much differences from stock kernel. same ramdisk w/ it last update. no autoroot, Touch Rec, FPS limit removed.

Doom Rec is Aire's kernel w/ DooMLoRD Recovery no Touch, FPS limit removed, no autoroot, support USB mount in recovery

hansip87 · Mar 24, 2012

Well ok, i'm using Touch version though.

Well would you try my method above to know the wifi issue?

I guess i can give temporary solution to wifi issue. Go here to read it.

1. Set default view in the preferences. Default stat > others, default stat type > since custom ref.

2. you can also go to menu> more> and set custom ref. It will reset the awake and screen on data.

6. Then open with others, since custom ref. That will clearly show the difference between awake and screen on data without waiting for a 5 minutes.

This is my routine every time I turn off the WiFi to see if it will cause battery drain. If it is not sleeping,i will turn on and off WiFi again and check again battery stat.

No issues here... I just stoped it

Are you sure about that? Using aire kernel still have that battery drain issue though. And I think the problem lies on the native library more than a kernel problem.

Well i am sure... Just attached my stats in morning to give an idea of drain in sleep mode... Wifi was On throughout ... It drained 1%/hr during sleep...

edit: btw.. Sirkay, why is fps still 72 after overclocking to 1.4ghz? Is it a new cap of 72?

Taverius · Mar 25, 2012

Could be you hit some other bottleneck than processing power.

72 max that we can get w/ our device

Is there any benefit of upgrading baseband to .64? I am still on .56 and don't have any issues yet...

The problem is not when wifi is on. It's when you turn off the wifi and haven't disconnected from access point. If left on I too didnt experience battery drain.

I tried this with the KA08 ROM and I do not see any change in battery drain when I just switch the WIFI off. The wifi turns off and the phone goes into DEEP SLEEP with out any problem. The battery drain is the same if I "forget" the access point before turning off the wifi....I have tried it with the Aire kernel and Sirkay's Touch Recovery modified version of this kernel and they both are behaving "correctly". The battery drain is typically around 1% per
hour.

I know this sucks to do, but maybe you can flash the KA07 ROM (there are
some bugs in the KA08 ROM that you won't have to deal with in KA07). In
my situation, I have huge battery drains with the the 3G build.prop tweaks,
so I typically have to undo these tweaks and I usually put in a longtime for wifi.supplicant_scan_interval...feel a bit silly pointing out this to you since
most of what I know about build.prop MODs comes from one of your
posts.....

Ok I got the battery drain issue it is the wifi.. Hansip temporary answer to the issue is to forget. Eifi iss effective. I slept for 7 hours and when I woke up it only consumed 3% of my battery during phones deep sleep..

Well wifi.supplicant_scan_interval is not solving anything mind you. I have that one too automatically added from zeppelinrox supercharger script. With your current rom, try to test it with my method few posts back after reboot. This issue usually popped up right after turning on wifi after reboot. Thanks.

I upgraded from .56 to .64 and haven't really noticed a difference, but I see CM9 recommending it so I guess there's a point?

P.S. BTW GUISE I left the phone w. wireless on while I slept and had 2% battery drop over an 8 hour period ...

sirkay · Mar 25, 2012

too many "error: variable 'type' set but not used [-Werror=unused-but-set-variable]" .... ggrrrrr

I did exactly as your previous post....rebooted the phone (using the aire
kernel) and KA08 ROM, connected the wifi and played around for 10 minutes,
reset the battery statistics and the cpu statistics, went to home screen and put
the phone down for 12minutes and about 30 seconds. Picked up the phone
and checked the stats....was asleep for 10 min and 51 seconds.....

My bad.... I wasn't trying to say to adjust the scan interval...I was just
trying to say that maybe there is something about your particular situation
that is killing your battery.....I was just using my own experience with
3G/wifi as examples. It is true, the wifi settings from the V6Supercharger
script are pretty good....but even the most conservative settings of
zeppelinrox's 3Gturbocharger scripts drain my battery so I had to unintall
them.

*raise white flag* .. i surrender build my custom kernel from sources. ignore errors when compile but after 30mins it end-up with .vmlinux needed for kallsyms.o no such file. ggrrrrr

build without guides seems doesnt work for me.. fuhhhhh :|

@Taverius give it a shot compile kernel from sources. c'mon! try compile under 64bit distro. or use VirtualBox.
