it's 9.14. Well, I can't answer your question and I doubt somebody else can - I haven't done any proper tests. To do this right I would need to test this on each kernel working with this rom using the exact same settings, apps and usage model (network signal, apps running, etc). All I can say now is that dori seems to be better that other roms I have tried but I don't have any proper stats to prove this and it's not necessarily only the kernel as apart from switching to dori I have also resolved a few other wake locks problems. Overall, the kernel change + plus the settings changes allowed me to extend the battery life to up to 2 days instead of 1.

ok cool, also can i flash new radio rom using supernexus rom or do i have to go back to samsung stock to be doing radio rom flash? also does flashing radio rom factory reset the phone or is it still all in tact?

s2 is known for getting quite hot on the cpu side, so if i can drop the volts a little hopefully it can remain running in a cooler state.

does dori kernel break anything feature wise in supernexus? if not looks like i will be flashing to it later on tonight.

---------- Post added at 01:52 PM ---------- Previous post was at 01:51 PM ----------

ohh forgot to ask, supernexus kernel has been 100% stable for me so far, is dori kernel stable too?
[Galaxy S II Android Development] PMOttawa:
I haven't needed to undervolt my SGSII for a while, but I found that with nearly any ROM/Kernel that allowed it you could take each level down by 50mv with no problems. There are more aggressive profiles out there that take the CPU down 75-100mv at some levels, but some of them caused instability and never made that much of a difference IMO. That said, the effect of undervolting on power drain was minimal, but I do think the CPU may have run cooler.
[Galaxy S II Android Development] slybunda:
cool ;) i got the system tuner app so i can monitor temps, the cooler it runs the better. and yea thats all i gonna be running just plain old 25 or 50mw drop in voltage so its bit cooler.

will get flashed to the dori kernel later today.

does flashing to the dori kernel require factory reset or is it just swap and reboot up?
[Galaxy S II Android Development] asti009asti:
Wipe the cash along with dalvik cash in CWM and flash it. Do a backup before doing anything though.
[Galaxy S II Android Development] slybunda:
cool, its not a handset that is in use at the moment, its going to be replacing the wifes 3GS, so iv installed apps etc on it.

is the dori kernel optimised as well as the stock supernexus kernel?

which app do you use to control voltages etc?
[Galaxy S II Android Development] PMOttawa:
Dori worked fine for me without problems. When I played with my voltages I used SetCPU, but I think all the CPU apps work about the same.

There are several flashable zip files, like Ultimate Kernel Cleaner that will take care of all the changes that need to be made before flashing a new kernel. You can get it here: http://xdaforums.com/showpost.php?p=19716290&postcount=1
[Galaxy S II Android Development] slybunda:
does setcpu also have like a tester in it to do stress testing on phone to make sure it stable?
[Galaxy S II Android Development] PMOttawa:
I don't think so... I learned my lessons by hit and miss, which isn't really a problem as long as you're backed up.

One thing about Dori, though, is that the dev says that the voltages have already been optimized, so the "usual" -50 setting may be too much. Again, I haven't played with voltages recently because I have found that Dori works well as is.

I use the Intellidemand governor, which is a tweaked version of Ondemand instead of the default HYPER governor. I find it a bit easier on battery without as much tradeoff as some others.
[Galaxy S II Android Development] slybunda:
yes i noticed the dori info mentioned its already tweaked the voltages so probably no need to mess with them any more. will probably stick the conservative governor on it to get as much battery power out as possible.

also the link provided to the kernel cleaner script goes to a download link which is dead. any alternatives?
[Galaxy S II Android Development] PMOttawa:
Hmmm

I have it on my phone, so I wasn't aware it was gone. Too bad it worked well.

The Dorimanx thread mentions this Kernel Cleaning Script as working well and designed for Dori. GS2KernelWipe

BTW. SetCPU does have a stress test function built into the INFO page. I've just never used it.

---------- Post added at 01:20 PM ---------- Previous post was at 12:55 PM ----------

I knew I'd seen something on the optimal scaling frequencies for the SGSII, so I went and found it. May be helpful to you in setting the minimum and maximum. I've had mine set at 200 and 1000 max as suggested and didn't notice any slowing.

Q. "I'm going to set scaling min freq as 100 mhz because my kernel supports it. Hope there's nothing wrong in doing that."

A. Wait! You may want to stay away from using 100mhz during screen-off or screen-on states for three reasons 1) It seems 100 mhz uses more power than 200 mhz. According to tests, 100 mhz accounted to 1 W / GHz and 200 mhz to 0.7 W / GHz, when both the cores were online. 2) 200 mhz can finish same task faster compared 100 mhz and thus hit deep idle soon. 3) 200 mhz is the 'sweet spot' of frequency in SGS II. ie, the frequency used in the calculations based on the optimal energy to run (Ex: In Milestone it's 550 MHz). So , 'energetically efficient' frequency for our CPU is 200 mhz.

Q. "I want to know is there's anything more i can do to improve battery life. I have already tweaked my governor settings but..."

A. Take my word. Best way is to limit scaling max freq to 800 or 1000 mhz. Sgs2 can do majority of the task with 1000 or 800 as the max. OCing to 1600mhz draws considerably more power than stock 1200mhz or even 1400mhz. Try scaling between 200 and 1000 mhz for a day and feel the difference.

FYI, the info is from here: http://xdaforums.com/showthread.php?t=1369817

ok got the new radio rom and the dori kernel flashed, set it up now with a -50mv on all cpu speed steps. for some reason dori kernel didn't already undervolt anything, stock 1.2ghz was running at 1275mv so dropped it to 1225mv.

its made a fair bit of difference to the cpu temperature but battery life is still crap in gaming. was running temple run 2 game, and it hits battery hard. oh well every little counts. I was thinking of limiting max cpu speed to 1ghz but since iv modded the hyper governor making it more conservative it doesn't go to 1.2ghz very often so may as well stick with it now.

will see how things go. but so far so good.

Hi,

I just restored 20K worth of SMS after flashing the ROM. The SMS restore finished but now SMS app just freezes saying "Loading conversations" Is there anyway to bypass this?

BTW, I've also uncheck the SMS Limit option on the SMS messenger before restoring.

Thanks in advance.
[Galaxy S II Android Development] hazwheel:
You really need 20k of sms's? Cos I'm guessing its taking a loooong time to build up a cache, probably falling down too much and not responding

ok sorted all my issues, out, flashed to cm10.1 nightly rom, and everything is working fine, noticed one thing, the battery life is considerably better on cm10.1 especially when the phone is with the screen on and in use such as web browsing etc.

will stick with cyanogen till supernexus gets more of its bugs worked out, especially the battery life issues.
[Galaxy S II Android Development] humercab:
Sometimes I have problem with camera. When taking pictures it starts blinking purple. And the taken picture is also purple on some places.. when I restarts phone everything is ok..Any solutions?
[Galaxy S II Android Development] asti009asti:
cm 10 seemed a lot slower to me.
[Galaxy S II Android Development] slybunda:
you are correct, cm10.1 is nowhere near as smooth as supernexus is. however supernexus when in operation doing web browsing and general screen on usage seems to give very poor battery life compared to cm10.1

id love to go back to supernexus but the added battery life of cm10 and the ability to do customisations such as have battery percentage guage on the status bar and lock screen is too good not to keep.
[Galaxy S II Android Development] PMOttawa:
I had the opposite experience. SuperNexus was way better on battery than CM 10.1 for me. Despite all being made with the same components, every phone seems to work differently.

---------- Post added at 08:56 AM ---------- Previous post was at 08:54 AM ----------

I do have to say that for me... I had a lot better battery life with Build 3 than Build 4... build 3 can't use the newest Dori or Syah kernels, but the stock was smooth and sipped power.

I never really gained much going to Build 4, so I've been tempted to roll back but, so far, have not.
[Galaxy S II Android Development] slybunda:
thats very strange.

did you find a way to get supernexus to show percentage for battery logo in status bar at the top of the screen? also were you able to remove the persistant search bar thats on the home screens?

i managed to do it with cm10.1 but not with the supernexus rom
[Galaxy S II Android Development] -Grift-:
I don't think you can get the percentage via any settings unless you install a app like "Battery Widget Reborn" and for the search bar just install any custom launcher like "Apex" or "Nova"
[Galaxy S II Android Development] slybunda:
cool, will stick to cm10.1 for a while and give the next update of supernexus a try.
[Galaxy S II Android Development] PMOttawa:
I use Apex and it deals with the search bar as you want it. I have it on some screens and not others.

Your comment on needing batter widget is incorrect. One of the few Mods that has been developed for this ROM (though not by Faryaab) is the Battery Mod, which gives you a few different battery percentage display options. Its a download and flash addition. Here's the link thanks to gatchak who created these mods back on April 4:

Problems with Build 4... gone with Build 3

I'd been having problems with Build 4 since I installed it. The two biggest being faster than before battery draining and - most annoyingly - a kind of hiccup or stutter that was particularly evident when playing back or streaming media but also noticeable on some games. Both problems were persistent on both Dori and the stock kernel.

Yesterday I rolled back to Build 3 and both of those problems seem to be gone. Battery consumption has improved significantly and my media playback "hiccup" is gone. So now, I think I'll stick with Build 3 until (if) Build 5 comes out.

If anyone else is having the hiccup problem, you may want to consider trying this.
[Galaxy S II Android Development] PMOttawa:
Nope...

Sorry all, while Build 3 did help my battery time, the "hiccup" my phone has been experiencing is still there.

Every 30 seconds to 2 minutes, there is a small "jump" in the phone. If I'm streaming audio or video, it stops. If I'm playing a recording, it has a very small gap. If I'm playing a game I experience a momentary freeze.

I'll still stay with Build 3 for the battery benefits.

Hey all,

I was interested in dual booting and have heard of quite a few people using dorimanx kernels so I flashed this kernel earlier. EDIT Flashed v9.14

I have been using this ROM and found it to be excellent for about a month.

I was wondering if anyone uses the different kernel modes available through recovery?

As when I selected performance the phone booted but the touch screen didn't work. The buttons worked fine so I gone back to the default profile.

Anyone else found this? Is it ROM specific?

Thanks

Phone is Dead

Guys,

I was on SuperNexus Build 4 and everything was running smooth. Today morning, suddenly the lockscreen won't show up after pressing the power button. I tried the Home button and nothing happened. So i pulled the battery out and tried to restart. The phone won't turn on.

Charging doesn't show up the charging animation. Connecting it to USB doesn't work. Vol Up + Home + Power to hard reset also doesn't work.

What could be the problem. I checked the battery in my wife's S2. Its fine.

PLEASE HELP !!! URGENT !!

Nandi

Did you try to hold the power, home and volume up for 8 seconds? I'm guessing you did tho
[Galaxy S II Android Development] PMOttawa:
If you can't get Power, you can't get recovery or download mode to use Odin. Which means you technically are bricked.

In that case, your last best hope is to get a dongle for an SGS II to reset the phone. You can buy them on ebay... or if you're lucky like I was... you can find someone on Craig's list nearby who has one and will lend it out for a little while.

Instructions for how to recover with a dongle are available here on XDA if you search.

I'm wondering what you're doing with the devices or ROMs to get such problems. Especially build 4 (stock kernel) is working without any problem for me. Very fast and good regarding battery life. But I do not play games on the phone.
[Galaxy S II Android Development] shuvabrata:
I have the same question. Build 4 was running superbly until my motherboard died. Without a phone now :(
[Galaxy S II Android Development] PMOttawa:
Well, of course, no two phones seem to work exactly the same even though they have the same components, they all have different histories in terms of tweaks, apps and updates. So just because one phone has no issues with build 4 it doesn't mean that no phones will. My issues began as soon as I upgraded from Build 3 and have mostly gone away now that I'm back on 3... even the hiccup problem is less noticeable.
