That's weird...
[Galaxy S II Original Android Development] KennyLegend:
Because wifi doesn't actually turn off for 25 mins or so after screen goes off so u only benefit from this sleep policy if Ur an infrequent user. If Ur llike me and keep checking XDA, bookface etc then Ur wifi will always stay on.

This is my situation after 34 hour : D This K2.1 kernel is WONDERFULL!!!
[Galaxy S II Original Android Development] aurelm:
the aosp bug is gone since the first 2.3.4 kernel update.

I'm not sure what the "latest sources from at&t means" and not sure how up-to-date they are compared to the compiled kernels that are offered. but the aosp bug is gone for 3 months or so. The fact that you still se high aos usage in battery info means just that you don't play around with your phone a lot and/or you have a lot of background syncs and 3g on.

Hardcore, can you give more details ? I want the screen tuning options plus the latest sound improvements in 2.3.5 but have no clue whether the sound improvements are in these sources that speedmod is built on. Otherwise I love this kernel very much and gg.
[Galaxy S II Original Android Development] ram3n:

What's your ROM ?

Are you using SetCPU or something else to UC/UV ?

[Galaxy S II Original Android Development] ql4y3r:
Thanks also.
[Galaxy S II Original Android Development] aurelm:
I also beg to differ. The bug meant that in 1-2 hours you could lose all battery and the phone heated a lot. If you get normal battery life (4-5 h screen on, 1-2 days with 1-2 h screen on, 4 days with 3g off) the rest is bla bla. The numbers don't matter, the bug is fixed. And stop looking at the damn numbers and just see if you have a normal battery life.

So it seems that kg3 in combination with this kernel works great

Some questions from a noob:

- is this with stock rom or frankenstein ?

- can someone post a screenshot with odin settings for above combo?

- will it wipe all ?
[Galaxy S II Original Android Development] hung77:
Even without uv i think this kernel is still better then ninphetamine's kernel.

I have used ninpo his kernel for a few days and undervolted with set cpu. This kernel doesnt support undervolt and already beats it hands down, battery usage is quite impressive i must say. This is now may favourite kernel, i hope CWM will be supported soon
[Galaxy S II Original Android Development] hung77:
I think you can use this kernel without any problem with the stock kg3 rom.

I am also using stock kg3 rom and have no issues.

Flash via ODIN via PDA, thats all.

No wipes

[Galaxy S II Original Android Development] spookyx:
Unfortunally, the AOS bug is in this kernel too, it is just unrepported in battery usage.

My drain for the last 8 hours of idle after full chargr wad 16%... So about 2%/hour.

I had system panel monitoring the phone. Suspend and events/0 are in the top.

Uploading pics right now doesnt work...

dear hardcore,

thank you for your efforts, time and as a result - perfect kernels. but, i'm sure you know, that the perfection has no limits. i just want to ask you to implement one more useful feature into the near future kernel - faster battery charge. i came to SGS2 form a Desire HD. since this feature was implemented into Lordmod's kernels the usability of the device was highly increased.

i'm sure i'm not along in requesting this changes and i hope you'll think about the implementation of such possibility into your kernels.

thanks in dvance.
[Galaxy S II Original Android Development] mariotme:
Hardcore thank you so much for such an amazing work and insanely superb kernel! Super fast and damn great responsivness bundled with best battery life among all kernels. You proved that oc/uv is just useless on our mobile phones!

[Galaxy S II Original Android Development] sahidmiah:
my friend how much difference between. kt41-and k2-1 performance wise.and is it worth changing
[Galaxy S II Original Android Development] donalgodon:
Faster charging makes batteries die sooner.
[Galaxy S II Original Android Development] blackspp:
Just an fyi:

After having used k2-1 since it came out I find it to be very stable and fast but battery consumption to be not the best. Leaving my phone in my pocket for the better part of the day results in quite some battery usage, much more than with previous kernels. I don't have any scientific data to back this up, just a gut feeling.
[Galaxy S II Original Android Development] ql4y3r:
Hardcore, when upgreded the cwm recovery to v5?
[Galaxy S II Original Android Development] BrandoHD:

---------- Post added at 09:15 AM ---------- Previous post was at 09:13 AM ----------

Don't think that version is stable as yet, people are reporting different issues in may different kernel threads about the stability of that particular version, with regards to making and restoring backups and other things.
[Galaxy S II Original Android Development] dzontra11:
For me the same.....
[Galaxy S II Original Android Development] bungknees:
I had a deep sleep issue when I first flashed the new kernel, and it was draining quite quickly, then I reflashed the kernel again and all my issues have gone. Deep sleep is back and battery life is good.

Hope this helps.
[Galaxy S II Original Android Development] blackspp:
Deep sleep is fine, about 90% at the end of the day. Now that is scientific data, so far as CPU Spy is doing it's job OK :)
[Galaxy S II Original Android Development] seburn:
SpeedMod SGS2 K2-1 has been the best kernel I have tried so far.

Will post follow ups.

During first calibration run I got 24hours life (3hours of screen on & wifi always on).

This should get better after calibration. My previous battery life was around 10hours running on stock KI3 fyi.

It does but it takes 25 mins for it to switch off. That's why wifi sleep policy to "screen off" only benefits you if ur a light/infrequent user. If ur a heavier user ( checking mails, xda, Facebook etc every few mins) it'll never switch off.

That patch is for the Galaxy S / Nexus S CPU (the single core Hummingbird), and it had already been implemented by Samsung on some of the later source code releases.
