Thats good, but I still dont see any reason not to include cpu speed and voltage adjustments. as far as I know it will not slow anything down, it will not reduce battery life, infact for users that choose to use it, it might increase battery life which goes perfectly with the rest of the kernel. so it can cause no harm for those that choose not to use it, only good for those that want to try it. and i dont think it requires much to implement (I understand its just scripts that are already available anyway?). i cant see any valid reason for NOT including it in a kernel designed for speed AND battery life, unless im missing something.
[Galaxy S II Original Android Development] :
Hmmm, it's interesting you say that, because I have Skype running all the time when on WiFi, and it doesn't seem to use any battery when idle. It certainly doesn't cause any wakelocks at all. Maybe there was a problem they identified and fixed since you last tried it.

Not that that helps you solve your battery drain problem though...
[Galaxy S II Original Android Development] gokhanmoral:
actually, you are missing something and that is the "super-stable" part.

undervolting and under(or over)clocking decreases stability.

you cannot imagine how many emails&PMs I receive just because of undervolting problems.

this kernel is never any less stable than stock and there is no modifications done that affects stability.

some roms have undervolting scripts by default and even those scripts won't crash this kernel because those scripts won't have any effect.
[Galaxy S II Original Android Development] tkalli:
From the first post in thread.

SpeedMod's core features are:

- Super stable:

No undervolting, overclocking or potentially unstable modifications

- Fast and smooth: Compiler and code optimizations

- Excellent battery life: Remove necessary logging and debugging

As stated in previous post to mine, you are missing the point.

does this not work with the latest CM7? i reset my phone to stock and loaded cm7 then tried to flash speedmod and all i get is a black screen after the initial boot screen...had to go back to siyah:(

what am i doing wrong
[Galaxy S II Original Android Development] :
It is Sammy rom kernel.
[Galaxy S II Original Android Development] Radikaal:
why would I be trolling? I gave my honest opinion and wrote the same things in both threads what I thought and my experiences. I compared both although not battery life that maybe is better on siyah, and since for most that is most valuable maybe it's the kernel for them.

Myself I want a superfast and lag free phone (why I bought sgs2) and im having great battery life as it with speedmod is so I dont care if siyah gives 30min more time on a charge. The difference in speed, scrolling and smoothness was very noticeable for me between the kernels, if its not for you well thats good for you!

@Radikaal

2.1 version has recognized scrolling lag problem, you must try the 2.1.1 or the 2.0 ;)
[Galaxy S II Original Android Development] boxy44:
I just flashed with odin -

[KERNEL] SpeedMod SGS2 [K2-13 Update3 CWM4 CIFS ROOT and while start up i get a yellow traiangle... i am on KJ2 stock with KI3 modem
[Galaxy S II Original Android Development] s2d4:
Have you tried changing governors? From what I have read, you don't seem to know/or have tried to change governors when testing... I don't think they are using the same default governor either..

The biggest indicator is when you just go lag, blah blah and 1hr testing of kernels....

Thanks for sharing your experiences tho, you are actually helping the supernoobs out there so they don't go fry their phones....
[Galaxy S II Original Android Development] tkalli:
So, what's the problem?​
[Galaxy S II Original Android Development] s2d4:
I flashed and got a yellow triangle, I didn't ask for it man, c'mon... but seriously though.. welcome the new comers :D

Old noobs should be shot :D of course this is a joke guys :p
[Galaxy S II Original Android Development] Radikaal:
Ofcourse ive tried changing govenors:confused: And why would i need more then 1h of testing when you can notice it after 5minutes that it just doesnt scroll as good in menus and homescreens as k2-13, and that opening stuff you actually notice things arent instant like on speedmod.

I don't really see your point here, i tried without setcpu, with setcpu, rebooted phone, cleared caches, reflashed kernel everything to get a fair compare. Also had high expectations on 2.1 because of the hype and release notes and after getting record benchmark in smartbench i actually thought it was awesome until i tested around in homescreens etc, for me itwas obvious the difference, so like i said if its not for you well im happy for you.:)
[Galaxy S II Original Android Development] s2d4:
Speedmod doesn't come with UV... doesn't this tell you something also?

For fair comparison, you have to have the same i/o scheduler, governor, voltage settings(taking into account default reduction in other kernels)... so what did you use and change to during your tests?

Another thing of note, I use petsasj modded launcher... another thing that was better than the lag on launcher pro.. so benchmarking based on that doesn't help other... Benchmarks aren't the most evident sign either, but you know this already.

Anyway, doesn't matter actually. This is definitely the best kernel for ppl who dont need or don't know or should not do UV
[Galaxy S II Original Android Development] Radikaal:
Yeah but i wrote i only compared the speed/smoothness and not the batterylife in both posts!

And i wrote i got better benchmark on 2.1 final then on speedmod but as you say, benchmarks don't matter!

And why wouldnt "benchmarking" / "testing" in golauncher and LauncherPro help others? If its lag free with speedmod and not with 2.1, thats evidence enough for me.

However, im testing siyah 2.1.1 and the smoothness is much better then 2.1 final which i was refering to before.
[Galaxy S II Original Android Development] s2d4:
umm, the uv part was referring to smoothness... didn't bring up battery life once...

what i am saying is that a different launcher wouldn't have lag.. so why even bother using it as a benchmark...

your testing methods and reports doesn't really bring out any conclusive evidence in your final claim.... 1hr kernel tests... I really don't think so..
[Galaxy S II Original Android Development] lrcquest:
use the Samsung galaxy s2 usb jig, search it on ebay. The easiest way to get rid of the yellow triangle.

---------- Post added at 10:30 AM ---------- Previous post was at 10:26 AM ----------

Does this kernel require 1-2 charging cycles to give best battery performance? I may be wrong but the stock KI3 used to give better battery life it seems. But only flashed yesterday (not more than 10 hours & battery @ 61%).
[Galaxy S II Original Android Development] AndreiLux:
No it's not. Flash CF-Root through Odin as that's a stock kernel, it will remove the triangle. Now flash back any other custom kernel from within the phone via CWM App or DarkyRom Tool and it will keep the triangle away. If you flash something custom again through Odin, it will reappear.

This way for example I haven't touched Odin in 3 months, without the triangle.
[Galaxy S II Original Android Development] Radikaal:
1. I didnt know UV caused phones to become less smooth?

2. And why NOT use the two most popular launchers as benchmarks when majority of all android users use them? Perhaps they dont want another launcher, ateast i don't. So it was a good comparasion for me

And yes, 1h is way enough to check the smoothness and speed of a kernel.

And third, gohkan even removed 2.1 final for 2.1.1 which changenotes are (UI and browser lag fix). Which was exactly what i was experiencing and commenting on, before he released 2.1.1.

Final conclusion: Speedmod > siyah 2.1 final in speed & being lagfree. I was not the only one experiencing this and even gohkan removed 2.1 and updated with exactly those fixes. Im not refering to 2.1.1 which seems alot better.
[Galaxy S II Original Android Development] KennyLegend:
The jig is still easier dude
[Galaxy S II Original Android Development] s2d4:
on the UI lag browser fix... . Granted i have not tested his kernel so never doubted this part but just your testing methodology..

1. yes.

2. samsung phone, touchwiz? less laggy than the launchers you choose to test with? It's like using windows vista as the benchmarking tool for awesome hardware..

3. 1 hr is seriously not enough, especially if there are multiple governors, multiple i/o schedulers...
[Galaxy S II Original Android Development] elite_gamer04:
Just flashed Big's ICS Theme (along with CheckRom V2.0), it comes with a Custom Boot Animation, I assume I will need to delete that before I put Speedmod back on?
[Galaxy S II Original Android Development] AndreiLux:
If you consider buying and getting the jig shipped easier than flashing twice via the other method easier... more power to you.
[Galaxy S II Original Android Development] sahidmiah:
Mate by the time u order a jig I bet I can get the triangle fixed
[Galaxy S II Original Android Development] beaver2233:
There's a difference between easier and waiting a few days... If you had the jig next to you of course its going to be easier..but who cares really...? Do what you want its your phone.... does it really matter which way you do it? NO
[Galaxy S II Original Android Development] ro4sho:
never mind i found it
[Galaxy S II Original Android Development] lrcquest:
U definitely are going to flash things later on.... & each time will u take the pain to do these steps???

& with the jig its super easy. Switch off phone, plug in the jig, phone automatically starts in download mode resetting the counter, remove jig & restart.

Done!!! & in less than a minute.

Searching this forum there is mention regarding the Jig by

cr0wnest

that it also resets certain scripts such as charging currents/voltages, more battery data. Stuff that cannot be reset by a factory...
[Galaxy S II Original Android Development] BrandoHD:
Flashing CF-Root does not remove the yellow triangle, the phone sees it as a custom binary because it is modified to add root and other bits, ChainFire has a tutorial in his thread on how to remove the yellow triangle after flashing his mod in his thread.

The only way to remove the yellow triangle is to flash a completely stock kernel, then using an app like CWM Manager to flash the custom kernel

The beauty of the JIG is that is also resets the "Custom Binary" counter, otherwise, it is not really needed.....
[Galaxy S II Original Android Development] Hilmesh:
I have just flashed this Kernel on XXKI4 from Intratech. can some body guide me as to what next? sorry if i sound like this but am new to all this :-)

[Galaxy S II Original Android Development] roufneck:
I'm so happy I flashed this kernel. 55% battery and 18 hours uptime, with heavy use. Usually by now the phone asks for the power cable.

Anyway, I want to take it to the next step: Flashing new firmware. I'm thinking about GT-I9100_XEF_I9100XWKJ2_I9100XXKI4_I9100XEFKJ1. Right now I'm still on 2.3.4.

This would be the first time so I don't want to mess up my phone. Correct me if I'm wrong, but I think this would be the right process:

Complete factory reset and cache wipe (I played to much with my phone, I want to start clean)

Flash the new stock firmware with ODIN

Flash CF-root kernel with ODIN

Extract zImage from SpeedMod and copy it to the phone

Flash the same stock kernel as the new firmware with ODIN

Flash the SpeedMod zImage with CWM Manager

Anything I forgot?

EDIT: never mind, found the guide to flash firmware and read that I need to re-root again.

EDIT2: ofcourse I forgot something. Step 3: Need to flash with CF-root in stead of SpeedMod kernel to get the cwm manager.

So yes, it is far easier.

[Galaxy S II Original Android Development] planetf1:
I think I finally cracked my high power drain / lack of deep sleep which started a few days ago.

A total reflash (+ restore) didn't help, so I've been increasingly freezing apps with running processes via titanium backup.

The consumer appears to be the stock VPN client.

A few days ago I installed "vpn widget" and got it working to see if I could connect to a corporate network. I subsequently removed it due to security concerns (awkward rules)

No vpn definition shows in the stock GUI, but I noticed a vpn process was still running (even though the widget was not installed)

I've now frozen the built in vpn client (VPN Services 2.3.5) & battery life has returned to normal -- for example over last 2 hours I've had 85% deep sleep

I can only assume that installation of the widget did some configuration change, perhaps to auto start the vpn client.

Next steps include unfreezing some of the other components I'd frozen in the process and checking the high consumption doesnt return. I'll probably cause another set of issues by being tempted to try KJ2/3 instead...

Strange problem here.

I am running K13 and get 54 h ..okay..but now after discharge my battery (and charge full again) i lose 3 % for minute....same apps..same kernel.No wakelocks..cpyspy around 70%...and that is strange too..

Any idea?

[Galaxy S II Original Android Development] Jodelaplaya:

with wich rom ?
[Galaxy S II Original Android Development] ewokuk:
well then im not missing anything, as I said, adding the ability to undervolt does not mean anyone has to use it does it? by default itll run at the standard voltages and be exactly as stable as it is now....... it does however mean those that want to try and get even more out of it can do so, at least they are given the choice. i dont see the problem.
[Galaxy S II Original Android Development] tkalli:
And those that do choose to use it and have problems will clutter the

thread with useless posts.

If you want undervolting, use a kernel that supports it.

hardcore has specifically stated he will not use it.

I suggest you respect his decisions, as it is his kernel.

​
[Galaxy S II Original Android Development] gokhanmoral:
you are quite right but also missing another thing: psychology :)

I tried to ask rookies who has uncontrollable instinct to use minimum voltage and maximum clock to use this kernel in the beginning of the second post in my thread. read it. that part will make those who think similar to you smile :)
[Galaxy S II Original Android Development] BrandoHD:
:confused:

Take off your blinders and understand what is being said to you, as said before, if you want certain features, use a kernel that supports it, that can't be as difficult as you are trying to make it out to be, stop trying to downplay the uniqueness of this kernel just so that you could satisfy yourself with the ability to UC/UV, OC.

Or get on Samsung's back and get them to implement the features YOU want, when you get through there, then maybe, just maybe, you may have a better case that you can present to hardcore :cool:

I've got to say the Colours are a bit off for me, I understand this has been tweaked here: - MDNIE color tuning (reduces over-saturation of color)

I haven't read most pages here, but this doesn't seem to be an issue for the vast majority.

Is there a way I can reverse this tweak? I quite liked the so called over-saturation of colours.

I have done factory wipe & cache wipe before & after installing the kernel!!! just to be sure...

Wifi usage only was co-incidental as i had to go out & the phone was on its first discharge cycle after flasing (from 88% to 5% in abt 24 hrs) So, i took out the sim card for usage on another phone & put the S II on charging. On return, i did not put the sim back :D.

So only wifi was active & i was using the xda app & then i noticied this drain of battery mentioned in my earlier post (20 mins 10% drop).

Only firefox is the additional browser installed just to check out, but i use the stock browser.

The spring zen live wp also active. Brightness in auto mode & autosync was fully on.
