Follow these instructions:

Back-up any files you might want to keep, (e.g. Pictures, music, saved data.) - You can transfer these back on to your device at a later date.

Make sure you have your ROM and N.E.A.K. 2.0.6x downloaded and ready to be transferred onto your device and flashed once your device is wiped.

Open up your device and remove your Micro SD card (just in case you wipe the wrong storage - internal and external options are sometimes the wrong way when selecting).

Reboot into Recovery Mode.

Mounts and Storage > format /sdcard (or) format /emmc - depending on which is your internal storage. (One option will format your phones storage.)

Mounts and Storage > mount (internal/external) USB storage > Plug in your USB cable and transfer your ROM and N.E.A.K. 2.0.6x over to your device.

Flash your ROM.

Flash N.E.A.K. 2.0.6x - (Remember to use the correct version, depending on whether you're SAMMY or AOSP/AOKP).

Wipe Cache Partition.

Wipe Dalvik Cache.

Fix Permissions.

Reboot device and let your phone start up and once you've got past set-up wizard, Google Play should restore all your downloaded apps.

Once the apps are downloaded, go to N.E.A.K. Configurator Pro app.

Apply all of the WIN!UV settings (rebooting when necessary).

If you experience no freezes, try applying ASV busfreq: Level 4!

Let me know how you get on! :)
[Galaxy S II General] sianzb0i:
Sorry, but whats the set permission for and change perm for which files?
[Galaxy S II General] sianzb0i:
One more thing is i cant get my screen on to get past more than 2 hrs (1hr+ is fine) before it dies. Issit my screen consuming too much juice?
[Galaxy S II General] hospital349:
Fix permissions is a function in Recovery; it sets every permission for every app/file once you run it.

I cannot say why you can't get much screen time... It could be because a number of things:

A rogue app... try this: Badass Battery and see if something is causing high CPU usage.

Screen brightness: Lower your screen brightness.

Other unknown problems: (hopefully others that use this thread might be able to give you advice).

Your screen time limitations are unusual and there is obviously something quite wrong if you are using WIN!UV. You could try a full wipe... explained above. See how it goes after the full wipe.
[Galaxy S II General] WhyLen:
Just have to wait and see the results :good:

Thanks a bunch hospital!
[Galaxy S II General] hospital349:
No probs :)

If this doesn't work then I really don't know what to suggest to you other than using Autostarts (featured on the 2nd post of this thread, if you aren't using it already) - if you disable everything on your device apart from system programs, then they'll only open up when you manually start on up.

It might be worth a shot, as many apps open in the background unknowingly at any given moment which might cause small stresses on your CPU etc.

It's worth downloading just to explore the possibilities. :good:
[Galaxy S II General] sianzb0i:
alright. I will find a day and flash ICS all over again. Been there but have had worst batt life, which forced me to come back (still the same ROM for my region though).
[Galaxy S II General] hospital349:
Technically UV = better battery so I really cannot imagine how/why WIN!UV would make your battery life worse.
[Galaxy S II General] sianzb0i:
The other time i wasnt on win!uv. However i did my testing and had similar settings. maybe ROM issue? i tried DXLP9 the other time. with screen off my phone can last reasonably long. its when i have the screen on doing heavy whatsapp and web surfing.
[Galaxy S II General] WhyLen:
ah.. i still am experiencing the same terrible battery life (12% loss overnight), even after doing a complete wipe.

may i ask what rom you are using hospital?
[Galaxy S II General] dcsoak:
Excellent battery life!! no freezes and all my applications run smooth.

I have a week testing it without problems.

Thanks hospital349 for settings :D

Ah, If it's any help, I'm using "CM9 - nightly" and "N.E.A.K. ICS v2.0.6x" with "N.E.A.K. Configurator Pro".
[Galaxy S II General] hospital349:
Hey man.

I'm currently trying out RootBOX (with minimal battery drain), before that Slim ICS and before that Pure ICS, all of which supplied fantastic battery along side N.E.A.K. 2.0.6x and WIN!UV. I would definitely try restoring to factory settings and formatting system and then flashing an alternate Rom. In this case, it might be the Rom that is causing your drain issues. :)

ALSO: You should check to see what is causing your wakelocks at night time. Something is obviously forcing your device out of deep sleep. 15% is too extreme, it might be an app, it might be your Rom. N.E.A.K. has great deep sleep ethics, so I can't imagine it would be the cause of your problems.

I'm really happy that you're happy. :D

I'll look into creating a new version once the new N.E.A.K. is released.
[Galaxy S II General] TheStigx:
Hey guys :)

I've had winUV for a couple of days now, and I am still ONLY getting 11 hours of my battery time:

http://i.minus.com/iCNPwvCJqCpbi.png

How is this possible :(?
[Galaxy S II General] hospital349:
Hey dude.

I can only really give you tips on how to better your battery life:

Don't use too many widgets, they're not battery friendly.

Make sure you have your data off when your screen is off. (The option is available on AOKP Roms, otherwise use: Green Power)

Use only battery friendly apps (for instance I don't use Facebook as I've heard it's a rogue app that drains A LOT of battery... I use Friendcaster for this reason - It has a dark theme option too, which is great.)

Uninstall unnecessary apps/system apps using Titanium Backup. I found this, it might deem useful to some: Removal App List

Use Autostarts to disable apps and system apps from automatically starting in the background.

Use a darker wallpaper.

Apply a lower screen brightness in darker environments and/or use: Lux to intelligently control screen brightness.

Use a dark theme - I'm currently using this: Blue Infinitium

Sync only what you need.

Also, be sure to use Betterbatterystats - As you might have wakelocks draining your device whilst your screen is off.

There are probably other things, but it's probably better if you use your initiative. Be overly cautious about what might be sucking up your battery and eventually, with WIN!UV, you'll be all set. ;)
[Galaxy S II General] banok:
I've tried many things, but definitely controlling your apps startups and your connections (via green power pour maybe juice defender) is vital to a great battery life.

[Galaxy S II General] sianzb0i:
those having bad battery life are you guys on stock ROM? or in other words, sammy-based ROMs
[Galaxy S II General] hospital349:
I've had great battery on AOKP, AOSP and Sammy. I've used all 3 types with 2.0.6x.
[Galaxy S II General] TheStigx:
I am running CM9 nightly. And at normal usage I get 11 hours.
[Galaxy S II General] sianzb0i:
hmm thats kind odd. im having great standby times. its just the usage part. I use whatsapp most of the time. I do not off data until i am going to sleep (by then i am already charging the phone). i also do web surfing, on stock modded browser. Use xda for awhile, few mins of games if im on the train. Thats about it. Auto sync is off.
[Galaxy S II General] hospital349:
To those with poor battery cycles,

Badass Battery Monitor

Use this. It'll detect which apps or system apps have the largest drain. If you can target your least battery friendly apps, perhaps you can uninstall or use a replacement.

This should help.
[Galaxy S II General] robinta:
Hi.

Ive just reverted back to NEAK 2.0.6 (Sammy) on Omega ICS Rom. I`ve applied the settings as per page 1 but after changing ASV value to 4 in recovery I found the screen would freeze not long after start up.

A change back to 3 in ASV has fixed this. Does this sound normal ? Will I see much benefit at level 3 ?
[Galaxy S II General] hospital349:
Yep, you'll still benefit from level 3 (and it's normal). You could also try level 4 with 1075mV (1000mhz) - It should help with your screen freezes (technically).
[Galaxy S II General] robinta:
Thanks.

Since my post the phone's been freezing a lot, so I've reflashed the kernel (after running a clearing script), fixed permissions and reset all voltages etc.

I then realised I had voltage extreme installed. It didn't seem to be running but might have conflicted with the neak configurator, so I've frozen it with titanium. I'll see how I get on now.
[Galaxy S II General] hospital349:
Yeah, despite you not manually opening Voltage Extreme, those kinda of apps usually automatically open in the background upon boot-up. It may have been the main cause for your problems... if so, try the original settings again and you should be all set. :fingers-crossed:
[Galaxy S II General] robinta:
Ive managed to get stability now on ASV level 4 - but only by raising hospitals settings by 25mv per frequency. Otherwise the phone freezes after 1st loading to lock screen. I still dont know why I cant get stability using these settings - could be the Omega ROM perhaps ?

These new settings are still lower than I`d used previously with NEAK using MagicConfig values, so I`ll see how usage pans out. Im interested in how playing music affects the battery with this, as I`ve noticed a much bigger drain playing music on ICS against GB (with the screen off) and noticed in hospital`s screen shots he quotes 4hrs usage playing music.

Does the SIO I/O scheduler give a `preference` with battery life against NOOP ?
[Galaxy S II General] hospital349:
You should firstly try raising the highest and lowest frequencies (1000mhz) & (200mhz) by +25mV, as you might not need to add +25mV to every frequency.

Undervolting capabilities differ from ROM-to-ROM. With Slim ICS, I could only UV with ASV Level 3. With Pure ICS, WIN!UV worked perfectly. Same goes for RootBOX. It really just varies. Either way, UV should be fantastic with +25mV for each step + ASV busfreq set to Level 4.

Also, in regards to music. It depends on not only the music player but the Rom you are using. Find a battery friendly media player to use to play music (research using XDA) - I recommend Poweramp as it has a built-in equalizer, (as I believe many stand alone equalizers drain battery quickly). The reason I mention that it is down to the Rom being used also is because I have noticed that many Roms have a much higher Media Server consumption. So it definitely varies from the Rom you are using.

SIO is a preference and works best for me. You aren't restricted from using any other and it's better to use what works best for your device. :) - I find SIO to be the most battery efficient scheduler out of them all. I have observed CPU frequency states whilst using Poweramp & can confirm that it only uses 200mhz during playback using WIN!UV's settings.
[Galaxy S II General] robinta:
Thanks hospital, I'll try and just alter the middle CPU frequencies to see how the phone responds. Im on the omega ics Sammy ROM (based on LPX) which might be susceptible for a media battery drain.

I wanted to run an AOSP ROM but hate 'losing' external sd location. I might have achieved better results with one over a Samsung based ROM.

I've been running poweramp as my default media player for over 2 years now. I might try others, but always come back to it !
[Galaxy S II General] shoulderbrah:
best

best thread ever!:good:
[Galaxy S II General] hospital349:
I wish. ;)

This thread is ranked at 4-Stars, which means it hasn't peaked quite yet.

I will continue working on it indefinitely, hoping to be awarded that extra start through my constant hard work and determination.

A lot of time, experimentation, freezes and S.O.D's go in to creating the right formula. I'm glad you like it! :)

Thanks for your support! :good:
[Galaxy S II General] robinta:
At the moment I can only seem to get the following to work without freezing : 200mhz (875mv); 500mhz(950mv); 800mhz(975); 1000mhz(1075mv) with asv set to 3.

The freezes are random.

Can the lowered gpu values 700/800mv also cause freezing ?
[Galaxy S II General] hospital349:
You could try 700mV/850mV or 750mV/850mV, either might work. It's so dependant on each individual device that I cannot say why your device won't go any lower, when others obviously do. :(

Crappy I know.

You could attempt the methods listed in WIN!UV: Problem Solver.

One of the many listed might fix your issues.

It's a long shot but once upon a time I had huge undervolting issues, whereas no matter how many times I reflashed kernel cleaners, roms and kernels - I was unable to UV without constant freezes.

Fully formatting my Internal SD solved my issues. Traces of system files from previous flashes must've existed which were somehow clashing with my current set-up. That's my only theory anyway.

Anyway... the instructions lie in the link. Please feel free to use and share those methods with others if they work. :)

Good luck.
[Galaxy S II General] robinta:
Thanks. I really appreciate your time and effort.
[Galaxy S II General] hospital349:
^ I've just this moment updated my previous post. ^
[Galaxy S II General] marco.fuce:
Hospital349.. just to know.. could you do a pre-undervolted version of the neak kernel? Such as phenomenal83 do for the speedmod kernel? Is it possible?? Tnx
[Galaxy S II General] sianzb0i:
I am quite sure its possible. However different device respond to different voltage values differently, for eg on 200mhz i can handle 825mV but your phone may not.

Of cos we can come up with a more generic baseline UV for everyone.

However i do not know how hard is it to implement, be it by flashing a script or file.
[Galaxy S II General] WhyLen:
hey hospital when restoring to factory settings, does it matter if i flash stock gb or stock ics?
[Galaxy S II General] hospital349:
I really have to agree with the post after yours. There's really no point providing users with pre-made flashable undervolting.

As convenient as it sounds, the inconvenience kicks in when one device can undervolt a certain amount, but another can't. It's easier for users to adjust levels themselves and re-adjust if they have problems with specific values. I really think it's much easier for folks to use a configurator to make these adjustments. :)

Either is fine. Whatever takes your fancy. You can only use N.E.A.K. 2.0.6x with ICS Roms mind you. If you're going to flash a GB Rom, you need to use N.E.A.K. GB Kernel. It is discontinued, although amazing nevertheless. :D
[Galaxy S II General] sianzb0i:
Yup,NEAK GB is still rocking solid. Im still on it up till today.

Btw hospital bro, i noticed a big batt increase when i dropped my brightness from 15% to 10%. Things are much better but i find it abit hard to see when im not indoors haha. I cannot believe 5% can make that much difference. Is 15 too consuming? As i dont really think it would drain that much. I will continue to monitor meanwhile.
[Galaxy S II General] hospital349:
I'm still a huge fan of N.E.A.K. GB. Still unbeatable if you ask me! :) - If it wasn't for the pleasure of using ICS Roms, I would still be using it now.

There's quite a jump in battery consumption between 15% brightness and 5% brightness, for sure. If you can get away with using 5%, do it. I always find that 5% brightness in darkness is more than enough. I may look into purchasing Lux Auto Brightness. You can configure your brightness for outdoor and indoor use. Very useful. There's definitely no denying that a huge brightness level is needed for outdoor use.

Otherwise, you could apply the option to use navigation bar finger sliding to adjust the brightness quickly when you need it. That's the method I'm using at the moment. It's quick 'n easy. :good:
[Galaxy S II General] sianzb0i:
I thought of buying it too until i know widgetsoid can do similar except it uses 3 preset values which also serves the purpose. You might wanna try it first before purchasing.
[Galaxy S II General] WhyLen:
can someone suggest a good rom that can works well with neak?? Thanks.
[Galaxy S II General] Addicted2Speed:
Ate the moment i'm using a "modded version" of your WinUV!:

ASV level: 4

Kernel Options: the same

CPU Control: 200-1200 / conservative / sio

GPU Voltages: 267MHz - 850mV / 133MHz - 750mV

Voltage Control: 1200mhz - 1150mV / 1000mhz - 1050mV / 800mhz - 950mV / 500mhz - 925mV / 200mhz - 825 mhz

Screen Control: Max Gamma: 15 / Min_BL: 15

Misc: Dual Core settings: Dynamic hotplug / Second Core off: 70 / Second Core on: 90

Running smooth with no freezes... handling at about 5h of screen time using 3G, Wi-Fi, gamming and lot of SMS :D

N.e.a.k + WinUV! = :victory:
[Galaxy S II General] Holgott:
Hmm.. My Phone had two random reboots today. Im using neak ics and win!UV with CM9 04/07. Is there any way someone could help me? System runs super smooth and i upped the voltages by 25mV alrdy. Heard about some protocols which are saved somewhere to provide informations about the system before reboot. Could anyone tell me where to find such a script and whether anyone could help with this informations?
[Galaxy S II General] hospital349:
Hey man,

Firstly, I would try Problem Solver in an attempt to be sure you have tried everything possible to narrow down your problems.

If none of those methods work, I would try sticking with the default voltages and try ASV busfreq Level 3. If you're still having problems; revert back to level 4 and try raising your

GPU

Voltages +50mV for both the highest and lowest frequencies. This might solve your issues.

Can I ask when the freezes occur? - You see, if it's when you're infliciting more stress onto your phone it might just be your highest CPU/GPU voltages that are the issues.

Also, be sure you haven't got any other voltage control app installed. This will more than likely clash with N.E.A.K. Configurator and cause issues.

Also, please use: CPU Spy and check to see which CPU Steps are actually being used. N.E.A.K. Configurator has been having a few problems. Some steps are used even when you instruct the app not to use them. E.g. 200mhz-1000mhz (but 1200mhz is still being used). If this is occurring, plus be sure to set your voltages to the following:

1175mv (1200mhz) - Just in case this step is being used.

I'm sure this problem will be solved in 2.0.7x along with the app update which is apparently happening this weekend. Here's hoping.

Also; you should be able to use aLogcat if you would like to look into what is happening during the time your phone freezes. However, it's completely useless when unfortunately undervolting is not kernel related but 'human error' related.

You could try selecting Settings > Developer Options > Show CPU usage (it should be there). That'll at least show you how high your CPU is when your device freezes.

Lastly, I would recommend using Autostarts, if you aren't already. If you make sure that almost all apps are disabled from starting up automatically, you'll notice a difference in performance from the get-go. I noticed that my device hasn't frozen once since I began using it. So many apps unnecessarily start-up in the background, unknowingly. I think this puts some strain on your device which makes it more likely to freeze. Especially if you have a lot of apps installed; as I do.

Anyway... let me know how it all goes. At least one of these methods might shed some light on your situation.

Good luck. :good:
[Galaxy S II General] hospital349:
Great find dude. Highly customizable. I'll have to give it a whirl when I grab a spare moment. Thanks!

I'm currently using OlloSII Monster Jkay and the results are amazing. I have all the perks from both a AOKP/AOSP & Sammy perspective. Best of both worlds. Minimal wakelocks. Themed. Tons of integrated features (using JKays Deluxe App). Utterly stunned by the quality. Plus TV-Out is included and works perfectly. By far the best Sammy Rom I have ever used. Beautiful.

That's what I love to hear. :good:
[Galaxy S II General] Holgott:
Ty man.. I will try raising gpu freq steps now and will see how it works.
[Galaxy S II General] WhyLen:
since you said it's a sammy rom, did you flash the sammy version of N.E.A.K?

I don't really get how to install this rom, i've downloaded the ollosII monster jkay final and aosp packages, but im getting fc's?
[Galaxy S II General] hospital349:
Yep. It's a Sammy Rom, so 2.0.6x Sammy is the kernel to flash.

Flash the Rom like any other Rom.

A full wipe is more than likely required and that's probably the reason for the FC's. Be sure to Format System, Format Data and Factory Reset and you should be good to go.

Also use the latest update: Sammy 2.0.6x - the slow-mo bug was recently fixed. Hence the link.

Be sure to use a Kernel Cleaning Script before you re-flash N.E.A.K.
[Galaxy S II General] WhyLen:
thanks! :)
[Galaxy S II General] Holgott:
Ok, here i go. I had no reboots since 2 days now, so I guess/hope my values are more or less stable. I got all the settings the same as in Hospitals Win!UV. Just changed the values showing in the Screenshots.

The thing i noticed is that my batterytime suxx a bit compared to the times u mentioned

I don't know why. I did a fresh install of cm9 because my batterylife sucked up before too and i wanted to test, whether a fresh install with no useless apps could help to improve. Meanwhile i think my battery is broken or smthg cause i cant explain the big differences in screen on times.

In the following theres a Screenshot with my partial wakelocks of bbs

If anyone could help me to narrow the screen on time with the one Hospital showed up in the first post, feel free to leave a comment.

Some Screenshots with mby useful informations.

(vbus present didnt changed since I unplugged)
