I had the same problem. my Android OS was 48%.

but now, I flashed each kerenls (stock and lulz) and Anroid OS doesn't exceed 6% both of them

also I heard this problem from stock kernel users. It seems a kinda bug in 2.3.3 or somewhere in the kernel source.

Try to change battery, and check it again. mine is fine. 5%
[Galaxy S II Original Android Development] nightranger73:
ghghgh... I had to take a break... the sea... the sun... :)

As I said I was experiencing a high android OS usage with battery drain but now it seems to be OK.

No more lag even using it at 1,2GHz and no more frequency changing continuously when idle.

It seems a fine work mate but let me test it a bit longer just to evaluate impact on battery ;)

bluetooth suck battery

Hi Tegrak, thanks for your kernel.

I am using lulz kernel build 5 and notice when i turn on bluetooth, the phone is sucking battery pretty high. About 3-5 percent each hour in standby. When i turn off bluetooth the problem is gone. I know bluetooth uses more battery but with the standard kernel i dont have this problem, at least it is not sucking 3-5 percent per hour.

Do you know how this come?
[Galaxy S II Original Android Development] nightranger73:

aghrrrrrrr.. "Android OS" usage is painful. it grows while screen off.

I have to use the stock kernel for a day to know differences about this :(

I've seen a same symptom on stock kernel. "Android OS" usage increased while screen off.

Is high Android OS usage a real problem or normal behavior?

Hi

I am flashing my network operator's stock XWKF4

Firmware info: PDA: XWKF4 Phone: NEKF2 CSC:H3GKF1

Which tegrak kernel should I have to flash

Thanks for help.
[Galaxy S II Original Android Development] tegrak:
Try ZSKF4 :)
[Galaxy S II Original Android Development] nightranger73:
It had to be there and if you keep your phone idle it is obviously the main process taking down the battery (it could even reach 100% if it's the only running process). That percentage alone means nothing.

It isn't normal if you still have higher values for it (over 50%) after a day of normal use (where other processes and display should have used battery letting it fall down) and you see your phone staying active while screen off and during this battery fall down at a 10% per hour or more

Hoping I've been clear enough on this as the whole idea it's still confusing me and trying to explain it in English doesn't make things easier

Strange thing here...I disable all oc and uv settings and now I'm on 1204 mhz with lulzactive on..the phone has the same smoothness as was in 1500mhz..smartbench showing around 4000( before was near 5000 but I can't see any other difference)..everything opens fast and smooth like before..so my question is do we have really to oc or it's better to only uv? Try it guys and you can see what I mean..

Thank you tegrak for your great work with lulz kernel.

I'm always using your latest kernel.. keep it up! :)
[Galaxy S II Original Android Development] nightranger73:
The sgs2 is faster enough and smooth even if set at 800MHz only.... but there are tasks that need the raw power of the exynos CPU.

if you don't need it overclocked don't overclock... it's quite simple.

I use the lulz kernel and thank Tegrak I can set my CPU to work at stock 1.2 and just let it run at full power when needed (mostly 3d gaming or long and tedious tasks such as database rebuilding)

[Galaxy S II Original Android Development] nightranger73:
AFAIK with 200MHz phone won't wake up and BTW I don't think it really help a lot as phone should go in deep sleep state turning off CPU and waking up regularly only when wake lock threads occur but staying at 1000 should make them end faster so the phone can return to deep sleep in less time... just my thought

WiFi connection issues have been reported even on the stock KG1 kernel, so it must be something related to the kernel/included drivers for WiFi ... It doesnt happen on all WiFi networks, but on most.
[Galaxy S II Original Android Development] tegrak:
Thank you to tell me.

I use same wifi driver (dhd.ko) from lulz build 3 and there was no problem with Villain 2.0.

so it can be caused by wifi setting values in init.rc or somewhere of KG1.

EDIT

not villain 2.0, no problems with older version
