Hey man.

Good to know you got the settings working.

Here's how I can help:

Firstly, check this out: vbus_present - It looks as if your largest wakelock is down to your device identifying itself as 'being on charge', which means that it might not deep sleeping properly (as the phone usually stays awake at 200mhz when on charge). You should use XDA to look into this problem further. The search bar is your friend. This wakelock appears to be quite important to your diminishing battery life though, so it needs sorting.

Also read this: Android System Wakelocks - it might be useful for your other major wakeups.

Secondly... use these methods as a guideline to better screen_on and all round better battery:

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

Make sure you have your data off & your syncing off when your screen is off. (The option is available on AOKP Roms, otherwise use: Internet Commander)

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.) - NOTE: You can find out which apps are the least battery friendly by installing: Badass Battery Monitor and making note of which apps use the highest percentage of your battery. If you are unhappy with those percentage, delete or replace the apps in question. Very useful.

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. (Useful, trust me.)

Apply a lower screen brightness in darker environments (I drop the screen down to around 10% brightness during a pitch black environment. Nothing more than that is needed), and/or use: Lux to intelligently control screen brightness. - Screen brightness is a very important factor of you battery life during your device screen on state.

Use a dark theme - This for AOKP/CM9[URL: ="http://xdaforums.com/showthread.php?t=1517344"]Blue Infinitium[/URL] and this for Sammy: ICS Domination - This method is also very useful as a way to get larger screen_on times.

Sync ONLY what you need.

Very useful tip: If you're on AOKP/AOSP/CM9, you can select an option to kill a foreground app by holding down the back button. This helps with battery a lot from my previous experiences. I use this method after I've finished using each and every app. If you're on a Sammy Rom supported by Jkay, the Deluxe App has the same option.

Also use a task manager to kill unnecessarily open apps. - ZDbox is great.

It's not really down to the kernel, as we would be all experiencing the same symptoms as you. Thus, it might be down to all of the above, plus the Rom you're using - so you could always try an alternative Rom. Some use less battery over long periods of time. Some have better deep sleep functionalities. CM9 is usually great when it comes to battery optimization, but it's definitely worth a shot, just in case.

Be sure to exhaust all options. :good:
[Galaxy S II General] Holgott:
Just downloaded badass battery app and lux autobrightness. Little question to hospital :can u share your lux values and which auto option u are on?
[Galaxy S II General] hospital349:
I'm using Dynamic Auto Option. It's definitely the only option for me.

Remove N.E.A.K.'s brightness values from Configurator Pro.

To adjust the auto setting values in Lux, I wait until a certain an adjustment is needed, at which point I enter the dashboard and adjust the brightness level appropriately and click 'LINK' - which then adds that setting to the list. It's the easiest way to do it. My list of values has accumulated recently due to the inconsistent weather conditions.

It's a no-brainer really. It's better to set the values yourself using the 'linking' method, as my preference might not be yours. If you get me. :)
[Galaxy S II General] banok:
Hey man... just dropped by to congratulate you on your work. V. 4.0 never needed further adjustments, and really nails the stability/tweaking balance. Great performance and battery life, no complaints.

Keep up the good work!

I dont know what is wrong, but my battery is now at 34% after 22h 48mins and my screen time is 1 hour 21 mins. I use Lux autobrightness with minimum values. For example -25% at 10 Lux and im also on Internet commander to stop my mobile data. When i watch GSam Battery Monitor there alre following values:

Phone: 0,0%

Screen: 33%

Phone radio: 13,6%

wifi: 4,8%

held awake: 0,2%

bluetooth: 0,0%

App usage: 47,6% with kernel most usage (14,4%)

next most appusage=Android-System with 9,4% followed

by XDA with 4,7%

Is it normal that Kernelusage is that high?

I dont get what is eating my juice to make such a big difference to ur battery lifes :(

Meanwhile i think my battery is bricked or smthg.
[Galaxy S II General] robinta:
Sounds very similar to my usage, i think the individual phone and rom makes a huge difference. I'm on omega ics. Plus 3uk network is 3g only.
[Galaxy S II General] Holgott:
Hmm... u know any kind of testing the battery?

I even did a fresh install of cm9 with minimum of apps installed (got 40 now)+autostart customizing+lux tweaks+Win!UV settings.

Most users talk in CM thread, that they got great batterylife with stock Kernel+settings, so i dont know what is wrong with my phone :(
[Galaxy S II General] hospital349:
To be bluntly honest guys, I really don't have a clue what other reasons could cause your below average battery life. I would recommend your next steps being to try out a different kernel. Perhaps an alternative kernel will suit your phones needs more. If you do try another kernel and you find that your battery life is still weak, it'll confirm that you need a replacement battery.

It's my final suggestion. It's difficult to pinpoint your battery issues any other way.

Obviously I would love for you guys to stick around, but if this is the only solution, it's definitely worth trying it out. :good:

Thanks buddy. I'm really pleased that everything's working out for you.:)

I'll be attempting WIN!UV 5.0 after the new N.E.A.K. release. I know Simone is releasing it shortly. :good:
[Galaxy S II General] robinta:
Thanks hospital in taking the time out to answer. I plan to keep neek but might do as you say and try another kernel for comparison.

The only way my usage differs is i use the internet a bit. Sometimes 2-3 hrs a day (opera mobile or dolphin), most figures posted are for minimal usage.

Im haopy with improved battery life and am not expecting 5hrs screen time +, as ive had to up my voltages c.50mv above your figures for stability maybe my ROM cannot hack your settings.

The only caveat i will add is that im actually running the 2000mah extended Sammie battery, so should probably have even better results than many.

just bought the PRO version and my 160mhz GPU voltage can go below 800 mV

Whats happening? i hope i didnt just spend $3 for nth

EDIT: It also cant set on boot. When i go next tab and come back, its unchecked already
[Galaxy S II General] hospital349:
You need to take this problem to Simone or nrk_2k. I have no idea what might be technically causing your problem. I'm using the pro app without issues, so it must be a problem with either your device or you're using the app incorrectly. Either way, I cannot help you without physically seeing what you are doing.

Cheers.
[Galaxy S II General] m4x0r:
Did you save the settings before you switched to the next tab?

[Galaxy S II General] hospital349:
Hey guys.

I've recently changed the GPU top voltage value for further stability. I think this should help those who have had experiences with freezes over the past couple of weeks:

850mV (267mhz)

The change shouldn't have a noticeable effect on battery life, as the highest voltage will only be used along side 267mhz.

As always, these values should be used as a guideline, so if you can undervolt further, please go ahead!

Any issues, let me know.

Many thanks,

hospital

New results and a new Hi-Score using N.E.A.K. 2.0.6x & OlloSII JKay Final.

Submitted by: hospital349

STOCK BATTERY - 1650 mAh

Music: 3.5 hours, Youtube: 15 mins, Vimeo: 10 mins, Chrome: 30-40 mins, Texts: 75-100, Phone Calls: 30 mins, Friendcaster: 10 mins, XDA: 15 mins, Games: 15 mins, Camera: 15 photos, Airdroid (PC to Android file transfer): 1gb+. Syncing: Chrome, Gmail, Haxsync, Dropbox. WiFi: 15 mins. H+/3g: Nearly always.

Note: (The small dip in the graph is when I had to replace a system file and set permissions. I was forced to restart my phone at this point. I have accounted for this.)​
[Galaxy S II General] dcsoak:
WOW!! great Hi-Score. Is using WIN!UV 4.0 or the new undervolting?

We will have to wait out the update of NEAK.... the next WIN!UV will go the same way? conservative and sio?

I am in CM9 and think I can get those results also :p but I use it outside the home, and brightness consumes a lot.
[Galaxy S II General] hospital349:
Hey man. Thanks!

I'm still on WIN!UV 4.0. I'm using OlloSII and it seems to be really battery friendly.

I'm not sure as to whether I'll be using Conservative + Sio

or

Lulzactive + Sio in the new release. I'm looking to begin creating a new stable version from tomorrow onwards.

I'll also be beta testing the new N.E.A.K and can begin sussing its UV capabilities. Simone stated that the new release will be VERY stable, so I'm excited about seeing how far I can stretch it. :D

Screen time is effected a lot by screen brightness, I agree. :) However, you should still be capable of achieving greatness, so it's definitely worth a try! :good:
[Galaxy S II General] sianzb0i:
I assume u mean pressing "apply"? I did it. Went over next tab, came back and "set on boot" is alrdy unchecked
[Galaxy S II General] hospital349:
Have you checked your superuser permissions? Make sure superuser has granted the apps root permissions, otherwise you might find the app unusable.
[Galaxy S II General] sianzb0i:
Just solved the issued. Had to create the init.d folder manually.

A innocent Request..

Dear Bro Hospital,

Can u make new test on Wanamlite 12.3 LPM(is it not release nw). if u can its the new point for wanamlite rom and NEAK kernel users. :)

I like to see your new UW for wanamlite roms.:silly::silly::laugh:

i think u will help us :fingers-crossed:

Thanks :D
[Galaxy S II General] hospital349:
Hey dude.

Thanks for taking an interest!

Unfortunately, to change from the Rom that I am using to Wanamlite I would need to do a full wipe - this is something that I don't really want to do, unless I really have to.

It would be far too much work to restore my apps and settings afterwards.

If you can test the settings yourself and would like me to help, I will help you ask much as I can! - You shouldn't have any problems though, if you use the WIN!UV settings. If you do run into problems, let me know and I'll guide you. :good:

I'm sorry that I cannot test this for you, but I'm going away in 1 week and unfortunately, I don't have much time to test other Roms. :)

Cheers!
[Galaxy S II General] lionsmatara:
Bro I'm still rocking on ur 4.0 UV :D:D:D

Did you have a working phone apk for 160 dpi?

How I can apply your setting im my phone .

I download N.E.A.K App. But not get option for i make your setting .

I can't purchase N.E.A.K pro for make this setting.

Any way for this .

Thank you for your work.
[Galaxy S II General] hospital349:
The phone.apk works at 160dpi, although it is smaller and off center. It's not a huge deal to me, as it is only occurs if you're dialing a number, not when you select a number from contacts. I hardly ever dial out, so I don't really notice it. The phone.apk is still very functional.

I tried searching for a MDPI Sammy Phone.apk, but couldn't find one that would work, as they're all CM9/AOKP compatible only. Crappy, I know.

You can only replicate the settings using N.E.A.K. Configurator pro...

If you really can't buy the Pro version... just apply voltages using: Voltage Control - but it really won't have the same effect.

Thank you for your reply.

This kernel can work with script if I create or not (like abyss) ?
[Galaxy S II General] hospital349:
I think so. I haven't tried, as I've always used the app, but it should work!

You're better off asking on the Official N.E.A.K. thread though. Simone will be able to tell you for sure whether you really can or not. I can't see why not though. :good:
[Galaxy S II General] sianzb0i:
Free version of voltage control doesnt really save your settings. I use setcpu+tegrak oc ultimate+VC (for the scheduler). But i just bought neak pro which does everything and UV to lower values too.

[Galaxy S II General] sianzb0i:
can try 825mV. I have been using 825mV all these while using my testing. still has room for allowance.

---------- Post added at 09:54 AM ---------- Previous post was at 09:52 AM ----------

btw, hospital bro. my GPU voltages will not go below 800mV (i can slide all the way to 700mV though), is it due to the ASV bus level thingy you mentioned before?

I just went into recovery. Couldnt find the ASV level option :(
[Galaxy S II General] lionsmatara:
To ASV

open CWM recovery >> N.E.A.K Options >>> Bus ASV Voltages :D

After u can select level what u need :good::fingers-crossed:

[Galaxy S II General] sianzb0i:
Just realised google maps dont like low GPU voltages. I can run 800 to 850mV fine on most of my apps. Then i needed to access maps and i needed to scroll thru a large area (tried both woth data on and off and also wifi) and it will always hang. The app will hang or it will keep jerking on the same spot and symtoms showing an unstable undervolt.

Therefore those who wanna stress test ur settings and make sure they are stable, you guys can use google map to stress test. My new stable voltage for 267mhz is 900mV :(

I'm just tampering with the settings a little bit. I want to make it's as stable as possible before throwing them in your direction. It won't be long! :)

I'll send you a PM as soon as it's ready.

oh no problem bro ;)

was quite excited when i woke up 12hrs ago and saw that you needed beta testers and signed up immediately :)

[Galaxy S II General] dcsoak:
For me with the lastest version of N.E.A.K. everything is better, really feels.

As before, I have no problems with WIN!UV 4.0, even short time with the new kernel version I noticed that my battery longer time.

I will continue testing, but for the moment all smooth.

CM9 + N.E.A.K. v2.1x + WIN!UV 4.0 = THE BEST :good:

if the new UV improves battery, hospital349 is "the chosen one" :fingers-crossed:
[Galaxy S II General] m4x0r:
Okay I think I fixed my freeze problems now.

I have tested all freqs with stress test, Google maps and Camera ICS and now it seems to be stable.

CPU :

100 MHz - 825 mV

200 MHz - 825 mV

800 MHz - 975 mV

GPU :

267 MHz - 900 mV

Can't wait for your new version :-P

As long as I can tweak the newest beta settings to perfection, the new UV combination will be mind-blowing. :D

I'll have them out by Thursday at the latest.

Let's hope I don't disappoint. ;)

I'm glad you have them working... not that it really matters now that the new settings are on your device... should blow away any previous issues what you had ;)

Keep me posted on your progress. I'm looking forward to getting this baby stable and released. The GPU underclock-undervolt should make a huge difference. It's a game changer for sure. :good:
[Galaxy S II General] sianzb0i:
Hospital, maybe u could create 2 sets of UV settings. One more generic one for the not-so-savvy, maybe cwm flashable or similar and one with tighter settings or even custom settings. Like i used to use 200mhz for lowest GPU as tegrak supports it but not NEAK PRO. By using 200mhz i make sure my GPU wont go into the next level for everyday usage or maybe even some more resource consuming apps. Voltages are quite close to 160mhz.

Just a suggestion :)

[Galaxy S II General] hospital349:
I was actually thinking the same thing earlier today. I'll look into it. :good:

They probably won't be flashable as it would probably be a little too much and wouldn't give people an incentive to buy the pro app which theoretically wouldn't be dev friendly :)

I would definitely try to create different levels for different users. That way, if one doesn't work, surely another one will. This way, everybody can be happy.

Version name ideas: WIN!UniVersal & WIN!UltraVoltz (or something along them lines) :cyclops:

Thanks for the input. It's always good to keep the creative juices flowing and this is surely a flawless idea!
[Galaxy S II General] marco.fuce:
I'll flash it immediatly. Starting from the most undervolted version! That's sure!
[Galaxy S II General] Ryther:
Hi hospital!!! I've bought the GS2 a month ago and i'm in full FMS (flash maniac syndrome :D ).

N.E.A.K. was my kernel of choice back when i was planning to buy the device and now i'm here sharing my opinion on your values ;)

First of all I have to say I'm lucky cause I'm stable with your values! Even for the MAPS test ;)

Second, can I ask for a little help on chosing the ROM? I'm not asking what is the best ROM, but what are your ROMs of choice other OlloSII? I've tryied it but i really don't like Samsung based ROM :S with PieR's aokp and WIN! values I've got a really good run, over 1 day long with 3.5h of screen on and 3g always active (synced every 15 minutes on screen off), but as you can see it's not even near your hi-score!

Last but not least, what's the meaning of "load on CPU"? It's the clock needed to complete the operation? Cause if we, like suggested for the gpu by sianzb0i, set the max cpu to 1200 and set "Second core treshold on" at 95 and "Second core treshold off" on 80-85, we can have more time on only one core instead of 2 with, maybe, a little smooth improvement? It's running a single core on a higher clock less power demanding than runnin 2 core at half the speed?

Sorry for my bad english :p

BTW, great job on the testing! Keep up this great work ;)
[Galaxy S II General] hospital349:
Hey!

Thanks :good: It's good to know you have everything working perfectly.

For more info on Roms and to give yourself a good idea of what is out there, I would look at this website: http://www.galaxys2roms.com/ It's constantly updated with each new release. You're better looking at each one and making a choice yourself. My Non-sammy recommendations are probably CM9 & RootBOX. I also like PieR's aokp :)

I think your screen time sounds standard to what you're using your phone for. If you're regularly and you're syncing a lot of things using 3g then it might be a big cause of your drain, especially if your phone is waking up every 15 minutes to sync. I don't actually sync whilst my screen is off, so when my phone sleeps, it doesn't wake until I tell it to, which makes a MASSIVE difference. Hopefully WIN!UV 4.5 will kick ass, as there's a huge change in GPU voltages. It should be a game changer and you should obtain a better on screen time in the future. :)

About the "load on" - Basically, it's when we want to 2nd core to be used. In the case of WIN!UV, the 2nd core won't be used until the work load is VERY HEAVY and then it kicks in. I find that the 2nd core is only really needed when playing Games or using apps such as Google Maps or Youtube, but as soon as these are being used the 2nd core kicks in anyway. The reason I have made it so high is because if the 2nd core is being used, it will definitely consume more battery, so it's better to set it to only be used when it's needed the most. In most cases, having 'load on' set to 90 doesn't effect performance in regular daily usage anyway, as most interfaces and apps can run with a single core, saving lots of battery life. :good: - It's a recommended setting, although you're welcome to set it to whatever you wish. ;)

If you have any more questions, don't hesitate to ask!
[Galaxy S II General] sianzb0i:
Bro! Thats the wrong way to start! you shld flash from not-so-low values to lower values, not straight to the lowest. Then you will never know how much your phone can handle.

Most imptly do backups and understand what you are going to flash :)

Sent from my GT-I9100
[Galaxy S II General] Ryther:
Thanks for the fast response!

My problem is the concept of "load"; what is the "load" of the CPU? I think it's a sum of the total work the cpu need to do but what's the unit of measure used to calculate this load? It's linked with the clock of the cpu? It's based on the bandwith of the bus? I hope I've made my "doubt" clearer :D

If the load is linked to the clock, then i think boosting the max clock to 1200 will give more time on one core and less time needed to cpmplete any "load", with a theorically improved battery AND overall performance!

Regards :D
