Flashed back to 2.6.7 which i had skipped over previously from 2.6.6. 94% deep sleep and no significant battery issues. I'll keep giving it a few cycles, but it's definitely better out of the box than 2.6.8 for me.
[AT&T Samsung Galaxy S II SGH-I777] msgfromside3:
Left 2.6.8 unpluged at 100%. Lost 7% in 6 hours while sleeping. No excessive drain at least. With 2.6.7 I lost abt 3-4% per hour with a few min of screen time so that sounds reasonable.
[AT&T Samsung Galaxy S II SGH-I777] moustro:
I am not usually the one to ask for help but I have been using MIUI off and on and I just cant get the battery life that I was experiencing with Entropys kernal and GB roms. I need some suggestions on how to get the most out of this kernal.

I have followed this thread so I am semi aware of the different scripts and what not. I currently have siyahs latest with the Tbolt scripts. I use SetCPU because I have pervisouly purchased the app but if VC is significantly better I will purchase that one. I use conservative governer with most freq undervolted and in call and screen off profiles. I did my research on Pikachus website and I tried to flash the screenstate scrolling tbolt but i kept going into boot loops. I usually can go a full day with heavy use on DD and only 8 hours with Siyah.

If steve, skatin, or someone could point me in the right direction for what scripts, CPU settings have worked for them it would be greatly appreciated.
[AT&T Samsung Galaxy S II SGH-I777] stevehkim:
hey there bud im always willing to help a brotha out. first off screen state newest version doesnt work. puts me in boot loops as well. secondly try using siyah 2.6.7 as i have found for me at least it has less battery drain. now instead of conservative gov try ondemand. you dont need any profiles as siyah already has built in sleep profiles so delete those. also delete the tbolt scripts for now. siyah 2.6.7 is perfect without them for me at least. now get yourself voltage control as its free in the market. change io scheduler to sio. adjust your voltages with either setcpu or VC doesnt matter. also in setcpu go to advanced tab. make sure sampling rate is at 10000. and up threshold at 95. you have to let the kernel settle in for a day or two. cycle the battery. try this out for a few days. you should be able to get at least 4-6 hours screen on time. also keep in mind the different variables with modems, signal strength, wifi signal as all these can hinder your battery life. ive found what works for me in my area so you must do the same. its a tedious process but in the end youll be happy. if you need anything else please let me know. good luck.
[AT&T Samsung Galaxy S II SGH-I777] moustro:
Thank you Steve! I will try this out for a couple days and see what happens. I appreciate the response
[AT&T Samsung Galaxy S II SGH-I777] skatin707:
I personally use Miui w/latest siyah kernel. I'm running CPU master price, but setcpu is fine. I underclock to 1000 and use ondemand/x and typically see 20+ hrs of battery life.

Right now I'm using the illusion rom with latest siyah.

Also, I use v6 supercharger 90% of the time. Option 9 on the most recent update.

Hope this helps! :)
[AT&T Samsung Galaxy S II SGH-I777] moustro:
I have heard the supercharger referenced. What exactly is that?
[AT&T Samsung Galaxy S II SGH-I777] OmegaWave88:
It's a script that's supposed to provide better multitasking and RAM management.

Thank you Omega and Skatin. I think I found it and am reading up on it now.
[AT&T Samsung Galaxy S II SGH-I777] stevehkim:

[AT&T Samsung Galaxy S II SGH-I777] Dungeon47:
Other than it being completely pointless on a device with this much RAM? Unless the SuperCharger works differently than it did on the Captivate last time I used it, all it does is adjust memory settings so that apps are unloaded before you run out of memory. If that is still the case, unless you are actually peaking out the some 850MB we have to work with, you should see little to no improvement by using it.

As I stated above, it may work differently now.

[AT&T Samsung Galaxy S II SGH-I777] skeet34:
I have ran the 3 latest kernels, from 2.6.7 to 2.6.9, each for 1 day in the last 3 days and my completely non-scientific assumption is that they all run smooth with great battery life. However, in running 2.6.9 all day today it seems to be even a little more snappy and responsive. Haven't had the chance to test battery drain fully yet, but if I get the same 4hrs screen on time and .5%/hr idle drain I was getting with the previous versions this looks to be a promising update. Also looking forward to seeing how the charging is effected with this update as well....

[AT&T Samsung Galaxy S II SGH-I777] Dsears1980:
I cant say much about battery life yet as it's only been a few hours but so far this kernel is very impressive, I did some testing using mhl with wifi and A bluetooth mouse and keyboard all at once, which would normally cause my phone to act pretty laggy on every other kernel even when overclocked. With this kernel, my mouse has not dissconnected once (which was a problem I was having with pretty much every setup I have tried so I had a feeling it could be resource related since it only happened when I really tried to overwork the phone), also, this is the first time I have been able to use hdmi without my battery draining, its actually gone up 1% in the last hour.

I'm using all default settings for set cpu except for that I turned on smartassv2. There is still some lag with the mouse cursor on the tv, (though far less) but I think that's just normal lag caused by the relay to the external tv. I was getting an easy 24+ hours on daily driver, I'll be very surprised if this can last as long with this good of performance. Although its pretty easy to switch kernels so I'm sure siyah will always have a place on my sd card from now on either way.

edit: USB connections in cwm and to my pc are working perfectly. I went to various complex webpages and watched some netflix and then some hd video I had shot to test the hdmi out, all worked flawlessly even with multiple bluetooth devices and all radios active.

For anyone looking to improve there hdmi performance this kernel has worked wonders for me.

This was using the latest unamed rom with no themes and very little widgets or anything as I was trying to maximize hdmi performance.
[AT&T Samsung Galaxy S II SGH-I777] Smith7018:

[AT&T Samsung Galaxy S II SGH-I777] jgrimberg1979:
PC mount is now working for me with 2.3. I found a very useful script that your flash in cwm that you flash right before you flash your new kernel. What is does is clean everything out from previous kernels. It is especially good when you are going from one kernel to a completely different kernel.

I was on 2.6.8 and battery life was the best I've ever had. Phone was at around 55% when I went to bed last night after 15 hours off the charger with fairly decent usage (over 1 hour of total screen time, several calls, web browsing, etc).

Flashed 2.6.9 before bed (flashed cleaning script, then 2.6.9) and battery seemed ok for the hour before I felt asleep. Looked a little high, nothing crazy.

Took the phone off the charger about an hour ago and drove to work. Didn't manually run any apps except opening Gmail and Email app to delete emails.

When I got to work, the I felt the phone getting warm in my pocket. I took it out and it was down to 93% and CPU Spy said the processor was almost full time at 1200 mhz. I checked BBS and it said 16m awake and 12m was Gmail. The rest were under 20 sec each.

Since I'm at work and can't be experimenting, I flashed back to 2.6.8 for the time being. I probably just did something wrong in the setup. I also had Set CPU set to 200/1200 conservative (no other settings modified) from the previous couple of kernel setups (for 2.6.7 and 2.6.8).
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Just flashed 2.6.9. I'll give it a proper run for the next few days.

Do you guys wipe voltage settings before flashing kernel(I came from 2.6.7) and then reapply settings after flash or just leave voltage settings as is and flash kernel. I can see wiping if your changing kernels but if simply upgrading current kernel, no need?
[AT&T Samsung Galaxy S II SGH-I777] jpstiehl:
Oh the irony

This is exactly what I would have written so, ditto. I'm wiping what's necessary and re-flashing as I type. Will report back I guess tomorrow with my results. Oh, a few differences. I use Voltage Control (you should check it out) and have my low set to 100Mhz. I also under-volt.

Thanks for the update! I read the release notes... I will wait for 2.6.11 as it looks like .10 doesn't really do much more than add the lionheart code. Gohkan even said battery life may not be as good in .10. And with 2.6.9 my phone has never been so smooth with awesome battery life... I am going to enjoy this for a few more days. ;)
[AT&T Samsung Galaxy S II SGH-I777] CamoGeko:
I'd say that's probably a good idea, .10 hasn't brought any battery saving tweaks really. After using it since this morning that is definitely noticeable, but then again that is because kernel hasn't settled yet.

So anyone looking for more battery saving tweaks I'd suggest to skip 2.6.10 and wait for .11. :)
[AT&T Samsung Galaxy S II SGH-I777] dmm5157:
Agree with the above statements. I had a little trouble flashing 2.6.9, so used the cleaning script twice, then flashed, then used the script again just to be safe. Since then, the phone is running fast, smooth, and battery life is outstanding.

2.6.11 changelog posted :

Changelog:

replaced the recovery with Hyperdroid Redpill Kernel Recovery. (Thanks to Hyperdroid team and Redpill kernel developer(s))

set the default cpu governor back to ondemand. conservative governor settings are still the same. ondemand governor settings are tweaked a bit (50000-90-5)

changed some mali internals (set staycounts for steps to: 0-1-1 and down threshold for second step is set to 35). I did not use AndreiLux’s settings for not breaking the compatibility with voltage control app but I highly recommend you try it because it can save a lot of battery juice.

some patches from upstream

No ETA on release (that I know of)
