[Galaxy S II General] sianzb0i:
today was at work so i almost had no time to play with my phone much. had my phone with me for about 60mins today.

GPU (either or both) speed and voltage didnt go quite well for me. Had a few lags and freezes today. And i needed to access google drive today and i made a picture offline for viewing. but i tried to open with gallery and it didnt respond. its totally black, only thing that appeared was the +/- signs for zoom. and it didnt respond after that. i set CPU voltages to stock to try again to make sure it was the GPU causing it. but i didnt have the time to pinpoint it was the voltage or the speed.

now im back on 160->267, 700->850 at the moment.

also played with the hotplug numbers. i used 55,80. not having very good experiences on games. I tried temple run. During game is ok. Its when the player crash then it starts to slow down. maybe i need to experiment with lower OFF value :(
[Galaxy S II General] lionsmatara:
Bro hospitle where are u? We miss you so much....:confused::rolleyes::rolleyes::(:(:(
[Galaxy S II General] sianzb0i:
Before hospital bro comes back, ive been experimenting a a new combo for some time.

I use NEAK pro and lulzactive app (so as you can guess i am running lulzactive governor). I/O will be SIO.

CPU voltages almost, if not same as win!UV. In the MISC section the hotplug values, i use 60/85.

In lulzactive app, i set the %-tage to 70/75%. (if you guess find my logic phailed, pls let me know hehe)

The main difference is my GPU values. I am not following what NEAK pro has to offer. Instead i wrote/ edited the init.d script to suit my usage.

im running 160/800 and 200/850.

I have been on this config for afew days. games and google map are smooth.
[Galaxy S II General] hospital349:
Hey guys, I'm back. :good:

How have you all been?

I'm not looking to update to 5.0 until I feel that WIN!UV is worthy of an update.

A minor/major N.E.A.K. update is probably required for this.

When the time comes, the next step is to create a system that works best for everybody. I'll be using a Performance +, ++, +++ and battery +, ++, +++ format, in which people can switch between different combinations of settings confidently, depending on their requirements. Obviously, some people want better performance for gaming, so they want a battery saving method that doesn't result in lower performance. Whilst some folks only use their S2's for low spec gaming, plus Youtube, Facebook and Web Browsing etc, and would be more than happy to maximize battery life by lowering their system specs.

I'll also be giving an option for folks to use Lulzactive, rather than Conservative. I originally used Lulzactive Governor in Version 1.0 & 2.0 and it worked okay, until I began using much more aggressive undervolting & underclocking and then it became a difficult Governor to control. I have spent much of my time tampering with various Lulzactive values to find the perfect settings. I'm almost there, so this option will be available upon the new release.

Variety is the spice of life, so it's better to give users a choice, rather than to set you all only 1 linear path. Furthermore, I think the new method will give everybody more confidence in trying out their own unique combinations and share them with other users, which is great for the thread and N.E.A.K. users alike.

I'll keep you all posted on my future intentions and progressions. :)
[Galaxy S II General] lionsmatara:
Bro.. lucky to see you again.. :D:D:D:thumbup:
[Galaxy S II General] sianzb0i:
hey there bro! glad to have you back :)

Actually the idea you have is great. :) how do you plan to implement it? thru init.d scripts? or just providing values or flashing zip packages?

I thought we should do it in a more "professional" way like how those ROM chefs, kernel devs do it (hope im not being too ambitious LOL)

I would very much like to be part of your team if possible. I may not be much of a help but i still feel UV is something worth doing and I myself have been also playing with it ever since I rooted my device when i bought it.

But currently my phone is with SSC. hopefully they solve my hardware issues (and do it right)
[Galaxy S II General] hospital349:
Thanks man! :good:

I'm not really sure about how I'm going to execute it. It'll probably be in the same format as always, mainly because if I use zip packages, it doesn't give users a reason to buy/use N.E.A.K. Config Pro any more and I really don't want to screw over the devs. I know how important those small funds are to Simone and nrk_2k. I know how wonderful it would be to be able to flash different WIN!UV values, but I couldn't do it to the devs. (As I'm sure you understand). :)

Also, I don't think zip packages will give people the same flexibility, as each device reacts slightly different to low values (as some devices can go lower than others). It's probably better to use N.E.A.K. Config Pro to make those adjustments, just in case small incremental changes are needed (per user).

I plan to make 5.0 the best version yet. I might look into universalizing the settings across multiple kernels in the future... although it would mean testing them out across each kernel, individually... one at a time. (If that's even possible).

In regards to being part of the team; I would love the help, especially with the up and coming beta testing - in which I would really appreciate any and all feedback. It's really important that I get each combination perfect, so if you feel that there are issues, these need to be corrected as we go along. Send me a PM for more info.

There will probably be a need for much greater assistance with plans to convert the same settings to other kernels, at which point I'll need a team to flash the many existing available kernels, for universal consistency.

By the end of the year, this thread will probably be a thread for any kernel user to learn and master undervolting/underclocking without the need to ask too many questions. There won't be a need to post issues regarding SOD's, freezes and reboots any more, because users will hopefully learn how to correct these issues themselves, overtime. That's the plan anyway. :good:
[Galaxy S II General] sianzb0i:
Thats alright bro :)

Anyways as for NEAK PRO, that will only affect NEAK users. And like you said, UV dont suit every device so in the end you will need to still buy NEAK PRO to fine tune. Of cos it would be good if you can discuss with the devs :)

As for other kernels,maybe you can start off with siyah first as thats the other most used kernel, in my opinion, as of now. But then again, siyah has extweaks which has a simplified UV already. And i feel is so simple, but its a very generic one.To fine tune you need apps like Voltage control, tegrak's apps, setCPU.

Hopefully 6-12 months down the road the xda S2 forums are still as busy and simone still support S2's NEAK. I should get new phone by then and i can flash any kernel i anytime. Now S2 is my one and only phone so I can only help test on NEAK :(
[Galaxy S II General] Qwerty123 \m/:
On which ROM was this again ? :)
[Galaxy S II General] hospital349:
:cyclops: I think at the time I was using OlloSII + N.E.A.K Sammy and ICS Domination - You should give them a whirl. :good:
[Galaxy S II General] Qwerty123 \m/:
Shall try this and soon :) :D

Any other good ROM you recommend ? :)
[Galaxy S II General] hospital349:
I really recommend Simplistic Rom V (the link in my sig) - It's truly awesome! :victory:
[Galaxy S II General] lionsmatara:
N.E.A.K vr 3 testing started. :eek::D:D;)Let's ready for WinUV vr 5... ;):D:D
[Galaxy S II General] hospital349:
I'm looking forward to releasing it!

It's all very exciting. :good::D
[Galaxy S II General] Addicted2Speed:
Let´s see if with the new update i can make 7 days in battery with phone on :silly:

N.e.a.k v3 ... Turning great in perfection ;)
[Galaxy S II General] Kigsuha:
I have set asv busfreq to level 4 but with the min gpu voltage is 700.

What's wrong ?
[Galaxy S II General] Ryther:
update the neak controllers app
[Galaxy S II General] Kigsuha:
I have too many bug with N.E.A.K kernel, busybox fail, SOD's and freeze without undervolting ..., Super user issues ...
[Galaxy S II General] hospital349:
As much as I agree that underclocking is the best method to save battery, there are reasons why this thread is committed to undervolting and not underclocking. Just as, there are reasons why the Galaxy S2 and such other phones where built with 1200MHZ frequencies and not 1000MHZ. I have underclocked in the past without any issues and combined with undervolt, the settings are still very stable and you do get much more juice. (BTW, this is mentioned in the 3rd post, below my settings, so I do get what you're saying).

However (and this is a big however)... performance via underclock is significantly lower than performance via undervolt whilst processing high CPU tasks. I play PS1 games using FPSe -

FPSe emulates considerably slower whilst underclocking, than undervolting. This is a huge downfall. I want to use my smartphone for the reasons it was built for, which is to do such tasks as 'emulation, playing games, tethering, shooting in high definition video, playing back giant sized mp4's, and doing many of this tasks, all at once.)' From all previous experiences, my phone has struggled to fulfil requirements whilst underclocking, but performance is almost completely unaffected when undervolting.

This is why I choose to undervolt and not to underclock and still, I experience great battery. Fantastic battery, in fact. For this, I am not complaining. I am praising my settings.

Thus, I made this thread to help others that desire the same as I. I think experiences with undervolting DO differ, but mine have only been positive.

EDIT: Obviously, underclocking does help retain battery considerably. If you're somebody who doesn't use your phone for CPU/GPU heavy tasks, underclock is a great option. Underclock + Undervolt is even better!

EDIT 2: If undervolting didn't work, I doubt developers would give people the option to do it. Plus, I know it works, as I have experienced great results.
[Galaxy S II General] can7:
cant find these settings in the app ?

Lulzactive App Settings

inc_cpu_load: 90%

pump up: 2

pump down: 1

screen off min: 4,@200MHZ

up_sample: 20000us

down_sample: 40000us
[Galaxy S II General] hospital349:
Are you sure? I haven't heard this from anyone else and you should be able to adjust the app settings to my settings...

I assume that you're using Lulzactive Governor + Lulzactive App?

I'm not really sure how else I can help you on this one.
[Galaxy S II General] Dunki3:
I which app are you looking mate? Those settings are for Lulzactive App
[Galaxy S II General] can7:
Ahhhh didn't have that installed only had the neak thingy from the play lol ill try it later once I'm home from work thanks.
[Galaxy S II General] nehalem176:
why lulz app revert default state every time reboot? add lulz app in startup say im not choosing lulz governor, seems like lulz app comes first then follow by voltage control... hospital, did u use stock hydro rom control for UV instead using voltage control app? just curious.... im uv with voltage control
[Galaxy S II General] hospital349:
Hey man. I'm actually using N.E.A.K. Configurator (for voltage adjustments) + Lulzactive App. I haven't had issues after rebooting. My advice is to use those 2 apps I've mentioned. I would also delete the Lulzactive Apps cache and date via Application Settings and then try the settings again.

Also wipe cache, dalvik & fix permissions, that might help...

Let me know how it goes. :)
[Galaxy S II General] nehalem176:
voltage control + lulz app, clear lulz apps cache, wipe cache and dalvik, and fix permissions

it works, thanks bro... you're awesome :D:D:D
[Galaxy S II General] hospital349:
I'm glad I could be of service. ;)

Just let me know if you experience any extra issues.
[Galaxy S II General] randomseasons:
Hey Hospital, I adjusted both my lulz and extweaks to 85% up 55% down, while this adjustment seems not to have any considerable effect, I firgured out just reducing the time of cpu up in lulz app from 35000 to 30000 increases my smoothness A LOT, although it will also increase the usage time of high frequencies, to defend this Im thinking about reducing the cpu down time too (it's currently the same as cpu up = 30 000). So the impprtant factor here is the refresh time, not the cpu load or threshold, I hope people can try and see, too.
[Galaxy S II General] m4x0r:
at the moment im using the magic config... is this config better?
[Galaxy S II General] ram3n:
There's actually any "magic" config. Just personal one's.

Try to UV as Extreme as your phone can and this is what I call custom Xtrem UV.

:rolleyes:

Sent via my S2 monster
[Galaxy S II General] Dunki3:
You have to test it yourself, for me is better.
[Galaxy S II General] hospital349:
I urge everybody to find their own perfect Xteme UV. What works for me might not work for them. Although, I haven't had many complaints. :)

What he said.

This is better for me, but I'm kinda biased. However, battery results do feel superior with my settings. ;)
[Galaxy S II General] m4x0r:
i already test it now... but only have one problem.

when i record a video my phone freeze after some times...
[Galaxy S II General] hospital349:
Sorry to hear that...

Try also raising the max GPU to this:

1050mV (267mhz)

If that doesn't help, try adjusting the GPU settings to:

800mV (133mhz)

and the Voltage settings to this:

825mV (200mhz)

Hope this solves your issues. :)

(Please make certain that all other settings are the same as the ones that I listed.)
[Galaxy S II General] wolfmenace:
Thank you very much hospital349 for this Guide... you are awesome!!! :D

One question, I am using Hydrogenics Rom + NEAK

The only thing that left to do now is to reduce the Vibration Intensity , not to disable vibration.

I cant seem to find this option in the ROM or NEAK Kernel....... any tips ? :confused:
[Galaxy S II General] pandemik.0:
Anyone undervolting the GPU also?

Stable:

GPU

100 800mv

133 900mv

The low idle UV seems to help battery life. Biggest difference is in gaming, phone just does not get hot.

Working on my UV... getting some odd crashes though.

Odd: If I lock my speed I get lower UVs than when I turn a governor back on. +25mv or so to get some stability.

mhz mv

200 825

500 925

800 1000

1000 1100

1200 1200
[Galaxy S II General] hospital349:
Thanks man. Appreciated! :D

No tips, unfortunately. I know that there is a vibration control option with the Fluxi Kernel, but not with N.E.A.K. - which is annoying I know, as the vibration functionalities are TOO STRONG for many.

Hopefully Simone + his team might get around to implementing this feature for future releases. Let's hope! :p
[Galaxy S II General] hospital349:
UV'ing GPU is absolutely fine and will edit the settings pretty soon (explaining that GPU UV can be done, as long as you don't need full GPU capabilities) - Taking into consideration that if I was to use a Playstation 1 emulator to run games with undervolted GPU, the games do not run at full speed. Not even close, in fact.

That's why I prefer to use the settings that I do, but please feel free to adjust them to your liking. That's what I want people to use them for and definitely urge people to UV GPU if that's useful to them. :)
[Galaxy S II General] Ryther:
On which ROM?
[Galaxy S II General] Kigsuha:
every rom

pfittech sammy, stock lpg, wanami lite, neatrom, Ollo SII etc...
[Galaxy S II General] Ryther:
Have you tried a full wipe? Tried the 2.0.6 version?
[Galaxy S II General] lionsmatara:
Our big bro Simone on big trouble :(

Please every One who love NEAK, please pray for Simone. If u done? I think he will get well soon.

Thanks.
[Galaxy S II General] Kigsuha:
I tried full wipe, but not the 2.0.6, but can you tell me why 2.0.6 version ?

I will try 2.0.6 version

Edit 2.0.6 looks to work fine but still problem with busybox, can't make solid explorer to work, it tell me busybox not installed.

And play store's busybox apps don't works :(
[Galaxy S II General] sianzb0i:
Over NEAK's history, 2.0.6 is one of the most stable releases
[Galaxy S II General] lionsmatara:
Bro hospital I Chang my kernel to dream. I'm request to you just test dream kernel. If u test it will help for all dream kernel users. Thanks..
[Galaxy S II General] hospital349:
I'm testing now. I'll play around with ExTweaks and report back ;)

EDIT: TESTING new settings... :good:
[Galaxy S II General] lionsmatara:
Wow.. so happy to see this bro..:eek: thank you very much... :D:D:thumbup:
[Galaxy S II General] hospital349:
Hey Folks.

WIN!UV is dead.

Welcome to the ❦ Carenel ❦ thread.

Over the next few weeks, I'll be expanding on what I've already created and streamlining all information to benefit our users. I hope you find it useful. :good:

Feel free to give feedback where feedback is due and make yourselves at home!

If anybody fancies the task of moderating, let me know so I can thank you in advance and credit you in the 2nd post! - (Here's hoping old WIN!UV users might come forward) ;)

Missed this thread!

hospital​
[Galaxy S II General] lionsmatara:
Wow... :eek::eek::eek::eek:

What a awesome explain with extreme stable settings bro...:D:thumbup:

Thank you so much.:beer: Hats off.....
[Galaxy S II General] King_Rat:
I must be freakin blind not to have seen this thread before :o

rather than asking lot's of random questions [like I usually do]

could an expert run their trained eye over my config & tell me what needs adjusting/added/etc?

Rom: MIUI 2.9.29 (secondary rom)

Kernel: Siayh 4.1.5

Battery: 2000 MAh (Samsung Original)

Apps:

Extweaks (I play a little, but I need to learn more)

What I've changed in ExTweaks [everything else as default]

-=CPU=-

*CFS TWEAKS = Linux Kernel Defaults

*CPU Undervolting = [-25]

-=AUDIO=-

*Head Phone Amplifier = 3

-=BLN=-

*BLN = True

Not much changed - as I mentioned earlier... just learning this stuff ^^

Apps:

No Frills:

-=Max Clock Freq=- 1.2 GHz

-=Min Clcok Freq=- 200 MHz

-=Governor=- SmartAssV2

-=I/O Schedular=- cfq

Scripts = Juwes RamScript [S97ramscript]

I'm a bit greedy [naive??] I want the best of both worlds i.e. performance & battery life ;)

I don't play many games... mainly my kids want ABs or Super Stickman Golf...

I run a few choice apps & I always re-name/un-install ram hungry/constantly running system apps e.g. [bug report/cloud service/google partner setup/MIUI stats/updater/etc]

Any help much appreciated :highfive:
[Galaxy S II General] hospital349:
Hey bro,

Welcome to the thread and thanks for your support.

I can definitely recommend the settings I'm using at the moment. They're featured 2/3 down the 2nd post, under 'recarenelmenddations'. If you aren't feeling adventurous and don't fancy playing around with your settings for a short time using the list provided, you could always use my 'recarenelmenddations' as a template and work around them, adjusting accordingly to suit your needs. (Although you might not need to adjust them at all!)

I'm currently on my first battery cycle with Dream-IRC and I have 40% battery left, 1 day 4 hrs on_battery_time and 4 hrs 10 mins on_screen_time. I've used my phone for gaming, as a wireless hotspot, calls, texting, maps and haven't had any issues.

Performance is perfect and battery is sweet!

If you have any specific questions, please feel free to ask. :)
[Galaxy S II General] sianzb0i:
great effort bro! I will definitely be there if you need my help.

---------- Post added at 12:58 PM ---------- Previous post was at 12:08 PM ----------

the OP was really really long. I personally felt there was way too much information.

For the GPU values (100mhz, 133mhz...) are those your current setup? 100Mhz may not be very helpful as most of the time it will bump to 133Mhz. Which is why i think most kernel defaults at 133Mhz onwards.
[Galaxy S II General] hospital349:
Had already changed it... I just never mentioned it. It's changed now.

Step 3: 133MHz, 160MHz, 200MHz. :good:

I really need to find out if there is a way to create hyperlinks, that way people can skip to the sections they want to look at by clicking the catagories at the top of the page. I have no idea if this can be done on XDA, but I'm looking into it.

I don't really want to shorten it, as I want the thread to be as thorough as possible. I don't want people to feel daunted either, so hyperlinks might be the best possible way to help people to find what they're looking for. :)

I could definitely do with an extra pair of hands if you're willing! Thanks man.
[Galaxy S II General] sianzb0i:
I have seen ppl done Hyperlinks but i dunno how to implement haha. Actually there are threads on all these topics you covered already thats why i think you should summarise examples of good settings instead of explain everything.

Just an opinion for some thoughts :) as for the hyperlink, i will look also try to look into it :)
[Galaxy S II General] hospital349:
You might be right bro. I'll revise the OP in the next day or so... to make it more user friendly.

Thanks!
[Galaxy S II General] chule250:
I posted this in other topics, but had no luck. I know thay 100mhz for deepsleep or min cpu speed is not stable for everyone, but for the lucky ones.. is there any way to check if 100mhz doesnt actually consume more battery than 200mhz? This happened with the famous HD2, and other devices, so lower freqs were not the best option at medium/long term.

Thanks in advance:thumbup:
[Galaxy S II General] hospital349:
Hey dude, sorry for the late response, I've been quite busy. :)

From what I understand, CPU frequency & battery consumption are different. Although battery consumption varies depending on how heavily you use your CPU. Voltages can always be adjusted through kernel control/voltage control apps and that's the best way of knowing what frequency actually consumes how much battery. Whether I have my lowest frequency set to 100MHz (800mV) or 200MHz (800mV), battery consumption isn't defined by frequency, but in fact mV (set voltages) - which in this case would be the same amount of battery consumed on whichever frequency you apply as your lowest. As you probably already know, frequency steps can be tracked by using apps such as CPU Spy, which will give you information and details as to how long each frequency is used for.

The only problem I have found with using 100MHz is that 200MHz is then often missed out and my device often jumps straight to 500MHz. I usually set my device to 200MHz-1200MHz because I know that with 200MHz set to the lowest frequency, the performance will always be better overall and my devices CPU tends not to jump up to 500MHz as much, whereas 100MHz tends to be far to low to perform the simplest of tasks and thus my CPU tends to force itself up to 500MHz way too often.

I would recommend setting your lowest frequency to 200MHz. The lowest volts for 100MHz and 200MHz are almost always identical, so I really have no use for a 100MHz frequency to be applied at all. Battery consumption is identical, the only difference is the overall unreliability of using 100MHz. Consumption tends be be higher when using it as the lowest step.
[Galaxy S II General] hospital349:
Updated & amended the 2nd post, added 3 different 'Editions' in to the mix and will be looking to add new variations in the future. Have fun playing around with them and of course, if there are any problems, just shout! ;)
[Galaxy S II General] sianzb0i:
Nice one bro. I try dormanx on sat and gave me many issues. But i think i will flash again with supernexus tonight, i guess.

Currently on chameleon ROM. Everything is stock except i use nova launcher. Batt seems to be going well. But it can read contacts directly from SIM which is a big no-no to me. Performance is just smooth.

So for those who wan fast and easy can try this ROM.
