This is an undervolt test version of my new StupidFast Kernel v1.2.3. This is a TEST release (NO VOODOO). This kernel aims to be fast, compatible, stable, and have good battery life. It is based on my StupidFast v1.0.36.
Code:
Changes since 1.2.2:
Fix for the 0.5-1.0 second pause/lag opening apps/drawer
Scheduling Tweaks
I/O Tweaks
Changes since 1.1.23:
Stock 1ghz @ 1225mV
Changes since 1.1.14:
Tweaked minfree settings
tweaked io scheduler
more compiler flags for cortex/hummingbird cpu
tweaked wifi scan interval to help with battery life
Changes since 1.0.36:
removed custom boot animation to trim size.
using kernel jhash3 instead of jhash2.
optimized compiler flags for the hummingbird cpu.
changed some kernel scheduling timings.
BLN disabled by default (configurable with [url=http://forum.xda-developers.com/showthread.php?t=823922]this app[/url])
You will see that the custom boot animation was removed. It's okay. If you already have v1.0.36, 1.1.4 or 1.1.23 installed on your phone, the animation will stay. If you're new to my kernels with v1.2.3, your old boot animation will be there.
I'm not seeing any lag on the phone. Gallery opens pretty much instantly. Settings->Applications->Manage opens pretty much instantly. Launcher Pro+ pretty much instantly appears when the phone starts up.
Testers could NOT find any audio problems with this kernel using the media player in JT's Clean ROM. I've tested Youtube and Pandora and have had no audio issues. Also, we couldn't find any issues with USB mount/unmount, settings changes, etc.
As always, if you find a bug or what you think might be a bug, let me know. This is NOT the final stable release of the 1.2 kernel. Stay tuned to #samsung-fascinate on FreeNode or @geeknik on Twitter!

Thanks to saps, jt1134 my beta testers and the kind folks that donated cash to the cause! Keep fighting the good fight!
sweet. dowlloading now.
Downloading also.
I like your kernels, but I just noticed I am getting a super weird output in ADB when I try using that. I also have superdark ROM so it could be either one.
Ok, I just rebooted and checked again and all is running fine with 1.2.2 in recovery, but not in running android system, must mean its the rom.
Downloading now.. went with full full wipe with jts clean, and still getting popping, on asop player, double twist, pandora
Besides the battery life which is supposed to be increased, is there any other benefit to UV ???? Longer processor life, runs cooler, etc.
What are the drawbacks, if any ???? Does performance take a big hit, etc.
I'm asking more in general terms. Obviously I will observe first hand with this kernel, which I'm downloading now.

In theory, as I know computer not cell phone, UV will allow it to run cooler, which does mean last longer (but is that really a problem?) and use less juice while still being as fast as before. If it runs stable you will not see a performance hit and it will better with the battery. It will just freeze your phone if its too low and requires more juice, really no harm can be done, overvolting is more dangerous as that burns up cpus, but you overvolt to make the higher frequency stable. Simple overclocking principals apply, you want the lowest voltage for your cpu frequency.

are you upping the CPU to 200mhz to run those? I am doing that and its just fine, although I never had a popping problem at 100mhz either. I just set the min to 200 because that cleans up a little bit of the lag too.
Possibly related, every once and a while my phone will just decide to press a soft key on its own, what is that? (that causes a slight skip in the music when I am playing it)

see if listening to it while hooked to power recreates the problem... i noticed for me atleast its only when plugged in...
I have it up to USB and its not skipping or popping right now, I am also using mixzing
v1.2.2 is the least fastest of all the geeknik kernels for me. There is 1 almost 2 second pause loading and exiting apps unless it was already in memory.
Still faster then everyone elses kernel. And so far battery life looks to be way better on this one but I haven't had it long enough to say for sure.
Nothing has changed on my audio popping issues so I am still using SetCPU at 200min still. I am short 6 hours of battery life like this by my best guestimate... which isn't a big concern for me- just reporting for those who need to make it thru a day without a charger nearby.
Never had any FC's with USB.
Touchwiz/JT's Super Clean ROM
And a thank you to geeknik for all your efforts! love how your pumping these out!
Kernal runs great! No unwanted sounds from the stock music player in jt's rom. USB works just fine. Thanks for your hard work!
are you using setcpu? if so that helped me fix it bumping min to 200... any one else having the problem might try that...
Interestingly enough, this kernel does seem a touch slower than the 1.2.23 regular voltage kernel. Hangs just the slightest bit when firing up and exiting dolphin browser and xda app. Still, appears to be MUCH better with battery life, as the previous geeknik kernels were ravaging my battery.
Definite progress but not quite perfect imho. Still thanks for all your work geeknik, you're killing it with these.
Also fyi, running custom blackhole, with sns and lp

This kernel is running fairly smooth, like the other 2. I can deal with the extra 0.5 second delay when first opening an app, as long as BLN is optional and battery life is extended. Thank you very much for taking the time to come up with these kernels for us. Other kernel providers tend to make their products less accessible for us XDA users, but you take the stress out of the search. Thank you again.

The uv kernel is a winner of course. I test these kernels for geeknik before he throws them up for the masses. Not just running quadrant [although I do that too] but going thru the real phone stuff itself. The manage applications load, replacing new dock shortcuts, gallery, apps and stuff everything we actually want to see improve with.
I for one never had battery issues with previous stupidfast kernels but I know some did, same this music crackling. It seems to me most of you that do are either running blackhold or deodexed rom though and quite humbly I'd look their for your culprit moreso than the kernel. If there was a music skipping issue from the kernel itself it would manifest itself across the boards but it doesnt.
Anyway, battery life is going to be stellar trust me, under light-moderate use Im only using like 2% per hour here swyping 8-10 texts per hour here, very good indeed
Hey Saps- I see ya on all the forums and your contributions have really helped me out...
That being said I keep seeing an overlook of real world usage in these testings. Can you guys test beyond stock apps? I mean checking stock should be the first thing you do obviously but how many people use the stock music player or the stock browser, etc? I am betting most the people that have the knowledge enough to test these kernels and ROMs aren't using stock functionality and apps.
Please test this kernel with the PowerAMP or Music PlayerPro music apps before writing off the issue.
Use Dolphin to check the internet, etc. Use K-9 to check email, etc.. ya know- use the popular apps during testing also if you could?
Audio cracking, FC's with the USB settings, and I even heard mention of live wallpapers having issues. These reports coming from 3 reported different ROMs.
How are you missing this?
I myself have had great success with battery life on the Stupid Fast kernels. Better then stock kernel for sure. But I've been having to run my battery faster by using my workaround to avoid the music crackling.

So I finally got the 10 posts I need to post here and for my first post I would like to ask, when are we getting Froyo for the Fascinate? I have been waiting for so long and I would like to say that I am starting to get tiJUST KIDDING
Against the backdrop of an imminent 2.2 release, I would like to share these kernels I haxed (read: kanged) together, because nobody else did and I was lazy. Based upon jt1134's recent kernel with the Voodoo sound patch that those of us with decent headphones have been having such a ball with these days, I integrated some fixes from the codebases of some of the very talented devs who are working on this phone.
Included in all of these are the Voodoo lagfix, Voodoo sound, and SirGatez's USB fix for the phone being recognized as a CD drive (also used by Adrynalyne).
Additionally, these kernels include SirGatez's fix to disable the VZW battery check, allowing batteries for the other Galaxy S phones as well as third-party batteries to charge on the Fascinate. Although it looks like for the vast majority of us with the OEM battery, nothing has changed and everything will continue to work as it has, this is untested. While the $6 battery I got from Hong Kong for the i9000 appears to charge fine, I haven't tested charging it very much yet and I must disclaim ALL RESPONSIBILITY should there be some issue with overcharging or batteries exploding. Again, this is only a concern if you are not using a Samsung-branded battery for the Fascinate. Well, the full battery popup works with the Chinese battery I have, and the phone is no longer charging it. Probably means that the fix is good for everyone with no battery explosions. Hooray! I still disclaim ALL RESPONSIBILITY as indicated above
As with all of the kernels based on jt1134's codebase, also included is the new red Voodoo-aware Clockworkmod Recovery. BLN is supported as well.
All in all, I am really happy that all these fixes from near and far work (well, AFAIK) together. I can't think of any fix/tweak that is missing, except for some of the more hardcore things like changing around the task scheduler and memory settings that don't affect day-to-day functionality of the phone as much, but are implemented by some of the real devs out there.
Update 1/31/2011: So as people have been discovering, the 7-step OC is causing some weird problems as far as call signals dropping out and various instability issues for some people, but perhaps not for others. I have spoken to SirGatez about the issue and it is a known issue with timings and such that largely boils down to faulty Samsung code (instead of waiting for a reply when using I2C to talk to peripherals as should be the case, Samsung likes to just shove more data down the pipe, or something like that). Luckily SirGatez seems to know his **** and has almost fixed the issue already in his codebase. As it turns out, although he is on a slightly newer codebase than pretty much everyone else still building DJ05/DL09 kernels (Linux 2.26.9.6 as opposed to 2.26.9, IIRC), the fact that the exact same issues showed up in my kernel and his with the 7-step OC helps him narrow his search considerably. Glad it helped, SirGatez.
For the moment, I would not recommend flashing an OC kernel - I've gone back to 1GHz myself because of the problems. I will see if his fixes are amenable to inclusion into my source tree with the view of releasing a new batch of kernels at some point in the near future.
Frankenkernel download links: (Voodoo only!)
1000MHz, 100% stock (standard) voltage settings: dropbox
1000MHz, Adrynalyne's more aggressive undervolt settings: dropbox
1200MHz, SirGatez's regular 7-speed OC settings: dropbox
1200MHz, SirGatez's undervolted OC settings: dropbox
It bears repeating that I take no responsibility for breaking anything. That said, it should all work fine, but here is an Odin package to go back to an earlier Adrynalyne-built Voodoo kernel + recovery if something breaks working on your phone. I believe this is Test6 from his current thread. dropbox This should also be useful for your after-Odin-to-stock hijinx, if you know what you're doing.
All credit should go not to me, codestealing kanger that I am, but to jt1134, Adrynalyne, SirGatez, and the other devs and users who I either stole code from, have asked lots of annoying noob questions to, or have flashed and tested my kernel. Especially SirGatez, who is apparently a decent dev, but has been toiling away in obscurity. Thanks for getting my $6 battery working, man, come say hi to the rest of us on IRC!
"included in all of these are the Voodoo lagfix, Voodoo sound, and SirGatez's USB fix for the phone being recognized as a CD drive (also used by Adrynalyne)."
Thank you!!!
Cool stuff, thanks. I look forward to trying some of these out and seeing how they run.
quick question.
If I wanted to flash the 1200 MHz UV kernel over my current kernel (adrynalyne's 1/21 UV voodoo), would I have to do any additional steps? I mean, it should be as easy as booting into red cwm and flashing it, right? I just want to be 100% sure.

Is the uv 1200 kernel also a 7 slot?
Also, if not already done can you upgrade this to BLN 2.3+? It adds blinking capability in BLN control and the newest blinky.

Yes, it's a 7-slot.
I'm not sure if it's BLN 2.3+ but I just tested on Blinky. It says the enhanced BLN is not found but blinks fine when I test it. Does that mean it's not 2.3+?
SirGatez is definitely an interesting character. Seems to be in his own little world, doing his thing.

i know / read that the voodoo sound fix does wonders for the headphone jack listening... however, what about for bluetooth media? (not calls, but actual streaming mp3's over bluetooth to a stereo... which sucks and I want it to sound better ).

This was the First thing I tried as I only use bluetooth headphones with my fascinate. And i can tell you that voodoo sound does nothing about the Bluetooth Audio.
I flashed this last night and was loving the battery life, but today I discovered that I couldn't make phone calls - when I click on the call button a box pops up that says I have no service. I flashed back to one of adrynalyne's test kernels and now it works. Just thought I'd let you know - other than that it was great tho, thank you!

Bluetooth is something that will be looked into. Go find the sound thread in the i9000 forum to see planned features and keep track of development.
I've posted these details in SirGatez thread for his kernel, thought I'd share them here since it's also applicable.
When using your kernel with SirGatez' OC settings, the CPU throttling is really high, it likes to spend times at higher clock rates when at rest. My remedy to it was setting a minimum processor speed of 200 MHz, then the at rest throttling was SUPER TAME, giving the greatest resting battery life I've ever experienced with no performance issues at all.
BUT, sadly your kernel shares the exact same "No Service" bug that SirGatez' does, causing erratic loss of service that has to be waited out, Airplane Mode switch is frozen at this time. This sadly had me have to give up the 7-slot kernel. Otherwise, great experience.

cheers guys
No, currently there is no way just to flash that stock rom over top. What battery life improvements are in the newer rom?
Well I don't know the specifics but I believe they optimized the power saving algos a bit, I know HTC has been tweaking them to try to squeeze a little more life out of that tiny battery.
Does it also have a custom kernel? I know the largest battery savings I've seen from my experience w/ custom roms came from a custom kernel that was geared to save battery life.
I can't find any information on the thread you linked about it having any battery saving benefits.

Yeah I know they've barely gotten roms w/ no bloatware out so far, which is a miracle in the turn around time from the device hitting the market. But sure they'll be there soon. So just interested in how this ROM manages to accomplish a battery savings.
Upon looking at the message in the thread about battery savings. If you remove bloatware and apps that constantly decide they need to be running you'll see a noticeable increase in battery life with that. You could also constantly fight to kill them and likely also see an increase in battery life. But the increase won't be as significant as when the custom kernels come about.
So if you aren't readily familiar with the manual process for flashing roms or say get a rom from a more reliable source (developer)... you might want to wait for roms to start showing up on ROM manager that'll automate the process for you and hopefully by then the custom kernels and other such options will be available. But I don't really trust a link for a image for my phone that sends me to a foreign website. You might want to check out adrynalyne's basic debloated ROM??

hi just wanted to ask if there is a ROM there that is as close as the original ROM of the samsung galaxy s II in terms of apps and looks but is tweaked for better battery perfomance?
cause my dad bought a SGSII almost a week now, and we only get about 5-6 hrs of it using only it. already did about 4 charge cycles. (4 only cause most of the time the GSII is off, my dad's getting a hang it yet)
config:
- stock android 2.3.3
- 3g auto
- auto backlight (but we are inside a mall so the backlight is isn't that bright & have strong signal)
- auto sync is off
- background data is on
- haptic feedback is off
- audible selection is off
- fast dormancy is off
- power saving mode is on
- juice defender app in balanced setting
apps running:
-skype
-messenger
it drains a LOT even in standby a lot more when using it (browsing, not yet chatting). my hd2 is much more efficient knowing it is not a native android smartphone...
is there a tweaked battery efficient rom there that is as close or at least still looks as the stock?
You can do three things,
1- Install Better Battery Stats and see under 'Partial Wakelocks' to see whats running on background.
2- Stay on Stock ROM and flash a kernel which allows Voltage tweaks and install SetCPU and Undervolt CPU. Ninphetamine 2.1.3 is such a kernel.
3- If thats too complicated for you, then flash an Undervolted kernel, like SpeedMod.
I won't advise you to change to a Custom ROM for battery backup betterment. But doing the above processes will certainly save some.

thanks for the quick reply, so custom kernels work with the stock rom...i thought it won't. i'm not that familiar yet with native androids cause in HD2 most of the undervolted kernels there are already built in the roms so i don't change it that much now with the NAND builds....but anyway, i'll try for the mean time # 1 & 3....i'm not that into that #2 tweaks yet in a phone that is not really mine....
It is proven that Stock ROM's with custom Kernels have sweet battery life. As with Stock ROM's they haven't tweaked anything, it's just stock and you flash what YOU want, whereas a custom ROM you're getting things you dont infact need.
I keep going back and forth from Custom ROM's to Stock ROM's.
Hi
I would also recommend looking at SicOpat's ROM (http://forum.xda-developers.com/showthread.php?t=1183774)
This is essentially a stock, rooted ROM with a custom kernel and I find it exceptionally good.
The other thing I would recommend then is to install Titanium Backup and freeze/uninstall a lot of the Samsung apps - WiFi Sharing, software update, *hub stuff. Removing these has a very positive impact on battery life.
Hope this helps.

I have also been troubleshooting poor battery life on my phone. I used to lose 10-15% an hour just idling. I reflashed Stock KH3 with the KH3 CF-ROOT kernel and reinstalled a few things (twitter, yahoo messenger, google voice, and some apps that don't sync data). Currently I had 18hrs now with 60% left. MUCH better. A lot of the time the phone was idle but I did listen to music, play some games, and browse the internet/chat, use wifi a bit. Phone only lost like 4-6% overnight. (sorry I don't have hard figures but I didn't document any of it on paper). I'm trying to find out what was killing my battery so I am installing things little by little but I would definitely recommend stock KH3. Seems great so far.
I think your problem lies with the wifi-sharing battery bug. I hear this is updated in newer roms. This was the biggest battery hog on my phone, but after noticing it, my battery life is excellent now.
When Wifi is turned on/off this erroneous process starts in the background called "Wifi-Sharing". It hides and drains your battery at a VERY fast rate. The remedy is simply to "Force Stop" this process after you use Wifi.
Let us know if that helps.
You could root the phone and install Titanium to freeze this process permanently.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
sorry for the wrong forum i got messed up in opening a lot of samsung galaxy sII threads....
i dont see the "wifi sharing" in my dad's GSII when we used it. and as with kies, i think JKG2 firmware is the latest, so i assume that the wifi sharing bug has been fixed there, yes?
i know it would consume a lot since the GSII has a big "engine" but i didn't expect it to eat a lot even on standby with only YM and SKype messengers running in the background.
i'm still observing it. i'm still running stock.
EDIT: i just used wifi to download an app then when look for running apps, i saw "wifi-sharing" is running but i didn't even turned it on
i just flashed Speedmod T38 kernel (it seemed less complicated to use ) now observing if my dad's SGSII gets better
at first: this is not a "whats the best rom" thread.
i have 2 very focused questions:
What are the idle times with those different roms?
Are there some Main feature differences?
Aktually im running cm11 m5 snapshot with smartassv2 Governor. its smooth but the battery life is kinda poor.
Im looking for a rom with long battery life. And i dont care about google now, talking to my phone(ok google) nor i need the special features from the standart samsung rom.
Would be realy helpfull if u can review to my questions. Greetings!
pls apologize my bad english.

There are no definitive results, I have used both and I keep coming back to Omni due to the fact that on SlimKat music stutters like crazy when the screen is locked. Also, Omni updates are small enough to update often without having to download a complete update, to many users this a huge deal due to data limitations in certain countries. As for usage, idle time etc, like stated before, that depends entirely on what is installed on your device. Install a bunch of apps that need to constantly receive data updates and you will have battery drain and very little deep sleep. Where features are concerned, you kinda learn to live with limitations due to missing features on a specific rom. If you really want, you can most likely find an app that will bring a missing feature to a rom. I see a lot of people throwing their toys out the cot because one of the other does not have a specific feature implimented, yet the developers have done so with good reason, usually either performance or battery life.
With all said, there are many roms out there, Omni and SlimKat aren't the only players. It's difficult to compare roms nowadays because you are never quite sure if your kernel tweaking or custom kernel with it's hundreds of tweaks is the reason for a device not going into deep sleep either.
Give them all a try and decide for yourself, nandroid backups and apps like Titanium Backup makes it so easy.

There are no definitive results, I have used both and I keep coming back to Omni due to the fact that on SlimKat music stutters like crazy when the screen is locked. Also, Omni updates are small enough to update often without having to download a complete update, to many users this a huge deal due to data limitations in certain countries. As for usage, idle time etc, like stated before, that depends entirely on what is installed on your device. Install a bunch of apps that need to constantly receive data updates and you will have battery drain and very little deep sleep.

Thx for your long, interessting and helping text!
im missing only 1 thing. if someone flashes all roms, doesnt install any apps. Only new rom and full wipe before, restart and tracks the time the phone has battery. Dont u think this is a possibility to compare the roms battery usage? i think there is no one who does this, but i probably will try this and put down a little table here. so people like me are able to see the rom with the best battery efficiency. so if they decide this rom has not enough performance, they can switch to "battery efficiency Number 2" and so on.
greetings

Sure you can do what you stated but bear in mind how will you compare the battery life across roms..
There should be some standardized test... Like looping video playback or some other method which does not change based on you usage habits..

Pa is another you're missing from you're list of developed roms. What you could do is test video playback, calls incoming/outgoing,one game of choice "high end battery draining game" and compere them all. As for the kernel tuning.. Read about what really happens and you will fine not a lot does happen with UV/uc .

You can compare but you have to use that phone for more days not like just one and you have to full charge and then discharge 2 or 3 times till the phone make the correct battery stats. So i think you can test but better with daily use or get an app that drains battey faster well i think this may work
