I have just this moment changed a couple of increments after realising that I had mistyped during my tired state last night.

Apologies to all, I'm really dumb when I get sleepy! :o - It should increase stability further. (Feel free to try Level 7 again before decreasing to 6 or 5.) :)

Adjusted values: 975mV (500mhz), 1225mV (1200mhz)
[Galaxy S II General] banok:
I had another freeze at level 6. Trying level 5 now. Let's see...

[Galaxy S II General] hospital349:
Thanks for the update. Be sure to adjust the following, as I have updated the settings, as I stupidly mistyped last night:

975mV (500mhz), 1225mV (1200mhz)

P.S. Are you using HyDroG3N-ICS? - I seriously have no idea how much of a difference a ROM will make... but I suppose this should be added into the equation. ROM + ROM VERSION, etc.
[Galaxy S II General] banok:
Now I saw the new voltages. Gonna try that in level 7. If that fails, I will go down to level 6, then 5...

[Galaxy S II General] Dunki3:
Same here, got some freezes on Level 7 and 6.

Now using Level 5 for about 4h and until now no problems.
[Galaxy S II General] hospital349:
Even the smallest incremental changes can vastly effect stability, so you never know, those changes may help :)

There's a huge difference between the Levels, so it really adds a lot of UV. If you are able to jump from Level 5 to 6 or even 7, it will have a huge impact on battery. Although even at level 5, UV will be impressive, so not to worry if Level 5 is the furthest you can take your phone!
[Galaxy S II General] banok:
Yes, HyDroG3N-ICS. No-go in level 7 again. Back to level 6 in the new voltages.

Enviado de meu GT-I9100 usando o Tapatalk 2
[Galaxy S II General] banok:
And back to level 5.

Enviado de meu GT-I9100 usando o Tapatalk 2
[Galaxy S II General] hospital349:
It seems as if that's the Level many are currently using.

I'm still using Level 7. I don't quite understand how several SG2's can be so different.
[Galaxy S II General] banok:
Me neither. But there's no point in crying about my processor, so it is what it is. Anyway I'm undervolting, improving battery life over stock specs. That should count for something.

Just a question: you suggest hydrog3n ics. Do you think a cm9 nightly + neak uv combo would be much worse? I kinda miss the cm9 profiles...

Enviado de meu GT-I9100 usando o Tapatalk 2
[Galaxy S II General] hospital349:
Agreed brother!

I can't see how it would make much difference. I think HyDro is just my preference. Give it a shot and if you experience great results, definitely report back :) - (or even if you don't.)
[Galaxy S II General] :
I switch between both CM9 and Hydrogen... I actually am stuck between these two! CM9 and Hydrogen are both awesome.
[Galaxy S II General] hospital349:
Setting changes:

screen off min: 3,@500mhz - (if you need it)

I recently experienced a freeze right after taking a 30 minute call. The screen off min was set to 200mhz which was probably too low for the cpu to handle whilst/after taking the call. I have raised it to the new level and tested several calls for the sake of finding out if the problem is solved. It is.

Other than that, I tested several screen off tasks with the new setting to see if 500mhz is used during those processes (eg. Music Playing with screen off) - only 200mhz will be used during this process because of inc_cpu_load: 90%, obviously. :)

Hope this helps anybody with the same occuring issue, or anything similar for that matter.
[Galaxy S II General] :
I see you switched away from Hydrogen too :eek:
[Galaxy S II General] :
:( that was the reason why i rooted my phone!
[Galaxy S II General] hospital349:
Yeah, It's pretty devastating and so difficult to find a GREAT replacement. I'm going through the motions of testing many other ROMS at the moment, although the bar is set so high. Crappy.
[Galaxy S II General] hospital349:
Settings adjusted yet again due to experiencing a freeze whilst attempting to start-up GTA3. The new voltages have stabilized the situation without any further issues. I've also moved down the minimum GPU mV.

I arrive home from my parents this weekend. I'll be sure to upload my latest results. I don't know about everybody else, but my battery stats are phenomenal. For light to medium use I lose 1% battery for every 12 minutes of On Screen time. For medium to heavy use, 1% for every 7 minutes of On Screen time. That has to be some kind of record. :D

I hope you're all having great experiences too. If I can help you, you know where I am.
[Galaxy S II General] ronaldo9_r9:
Can these be applied to gingerbread roms i am using turkbey v33 and tried magic config and its gave me 3hrs and 24mins on screen time with 50% battery remaining. I am not heavy phone user just check emails,facebook,xda every other hour. I want to give these settings a go. I am using neak kernel.
[Galaxy S II General] :
I use CM9 nightly dated 20120524... and it's fantastic. Really happy with it even though Hydrogen was freaking awesome.
[Galaxy S II General] hospital349:
I cannot see why not. You can always give it a go and if problem occur, just boot into recovery mode and reset your voltages, etc. :)

Let me know how it goes.
[Galaxy S II General] hospital349:
Would you say that CM9 is similar to Hydrogen?

I'm really enjoying Paranoid Android so far. Their 'Tablet Mode' and 'Hybrid Mode' are tremendous and their are plenty of other options/settings to keep me happy. Plus the ROM is aesthetically pleasing.

I'm going to give it the benefit of the doubt and stay on it a while longer and see how the battery is. :)
[Galaxy S II General] Dunki3:
I've change Hydrogen with CM9 20120524, and have no regrets.

I'm still testing the CM9 kernel, but probably i will return to N.E.A.K. very soon :)
[Galaxy S II General] hospital349:
Can I ask what you think are the most prominent things about the ROM? Whether it be speed, battery, features...

I'm very interested in giving it a shot if you can all sell it to me ;)
[Galaxy S II General] Dunki3:
I'm not trying to sell anything :) It's you decision.

Battery life, can tell for sure because of the first circle of charging, is almost as good as i get with Hydrogen + NEAK.

The ROM is butter-smooth and lightning fast :D

I like the constant development of the ROM (for me this is important) and the notification of CM9 (the icons are nice and light).

The thing that i miss the most from Hydrogen is the brightness slider from the notification, but the widget button seems to do the trick :)
[Galaxy S II General] hospital349:
I know you wasn't trying to sell me anything, I wanted you to sell it to me. I've been interested in giving it a try for a REALLY long time, so any info given is appreciated!

I'll give it a whirl. Kinda cutting out the middle man theoretically, as many of the updates that appear in AOKP ROMS are built into CM9 updates. At least by using it, we'll never miss out on a new build ;)
[Galaxy S II General] Dunki3:
The difference is that we lose the AOKP features, but we lose the AOKP bugs as well :)
[Galaxy S II General] hospital349:
I think it's probably a win-win situation because there's app out there for everything, which means you don't necessarily need the AOKP features to do the things you want to do with any phone. :)

I didn't really use many of the ROM Manager settings anyway, so I really don't mind. I like simple.

I'm trying CM9 now, to compare between Paranoid and possibly one other ROM (which I haven't decided on yet) before making my choice.

Thanks for the info buddy. Very useful.
[Galaxy S II General] Dunki3:
You should try this also http://xdaforums.com/showthread.php?t=1403044 a lot of buzz around it.
[Galaxy S II General] hospital349:
Yeahhh! Seems like a great HyDroG3N-ICS alternative. Probably almost identical in many ways - Although it does feel snappier and there are a few more additional options in ROM Control. I'm really enjoying it from the get-go. I hate change and when HyDroG3N burned down to the ground, I thought I'd have to adjust to something different, but this is new without being alternative. :)

Definitely going to stick with this for a while. It has the potential to be my new ROM for sure.

Works perfectly with N.E.A.K too - Going to begin battery life testing shortly.
[Galaxy S II General] Dunki3:
Yes, it seems to be a good ROM. I will install it today and give it a go and compare it to my experience with CM9 (for now it's flawless).
[Galaxy S II General] hospital349:
I tested it too... CM9 that is. Really minimal and elegant. :)

Again, I don't care so much for the AOKP features. They aren't a dealbreaker for me. However, Hydra is so much like HyDroG3N, that it's difficult to say no. :p

Hydra also looks as if it gets updates more frequently than HyDroG3N did, which again is a plus-plus.
[Galaxy S II General] django84:
I come from Hydrog3n'ics associated with neak kernel and I really love them. But now I try CM9 that is very similar in smoothness and battery, but with the stock kernel. Every time I tried to use neak I got always ramdom freezes.

Now I want to test Hydra with neak. Do you think it's a good idea ?
[Galaxy S II General] hospital349:
As much as I like CM9, battery life with N.E.A.K. + CM9 just wasn't the same. For some weird reason, battery went down quicker.

I'm now using N.E.A.K. + Hydra and it's the best it's ever been. These are my latest stats for the 1st cycle since flashing the ROM: (Moderate-heavy use and shockingly gooooooood)!! ;)
[Galaxy S II General] hospital349:
If you're having any kernel related issues, try a kernel cleaner such as this:

http://xdaforums.com/showthread.php?t=1363738

and then re-flash the latest version of N.E.A.K. Then wipe cache, dalvik and set permissions.

Then adjust your kernel votages etc (if you wish to do so). :)
[Galaxy S II General] Theodhoro:
Thank you for this thread, very helpful. I will test your settings today with hydra 1.2.1 and neak 2.0.5.

I have juste one question, your settings about the second core threshold (Second Core off Threshold: 75 Second Core on Threshold: 95) are they not bad for the first core? He works more as with the default settings right? Can it cause problems long-term, because the first core worked more so is more worn?
[Galaxy S II General] hospital349:
Hey!

You're very welcome.

To answer your question: Very doubtful. The whole point is that when the 2nd core is REALLY needed, it kicks in. There are 1-core phones out there that run the same apps and games that 2-core phone do, so there really is no difference. It's basically a method of saving battery without effecting performance. My performance hasn't changed but my battery life has.

Even of I changed Dynamic Hotplug to Single Core, it still wouldn't have a great physical effect on the hardware (apart from general wear and tear that happens to a phone over time.) It would however have an effect on the performance of your phone. That's why Dynamic hotplug is set to 95% and not 100%.

100% would have an adverse effect on performance. 95% won't.

Hope this helps you to understand a little more. :)
[Galaxy S II General] Theodhoro:
Yes it helps, thank you. I will try the same settings so :)
[Galaxy S II General] Kaizneight:
Hm...i am having problem atm...whenever I tried the setting, and i leave it idle for 4 minutes or so, when try to unlock the S2 from lockscreen, it hang and i have to take the battery out to be able to turn my S2 again...any idea why this happened? I follow your setting btw from the 1st page..possible due to ASV busfreq? I'll change to 5 or 6 and see what happen
[Galaxy S II General] hospital349:
ASV busfreq @ Level 6 should solve your problem.
[Galaxy S II General] Kaizneight:
same problem with lvl 6...i try reflashing kernel and reconfig
[Galaxy S II General] hospital349:
Please do. Report back. Kinda confused as to why this might be happening. You could always try raising 850mV (200mhz) to 875mV - See if that helps...

EDIT: Also try removing all voltage settings from within the recovery options and then flash Ultimate Kernel Cleaner - Flash N.E.A.K. right after doing that and then reapply the voltage & Lulzactive settings.

That may work...
[Galaxy S II General] Kaizneight:
Yep...finally get it working. Delete all settings from NEAK options, wipe cache, wipe dalvik, use kernel script cleaner, reinstall NEAK, and finally reconfigure..no more hang..thanks, hospital XD
[Galaxy S II General] hospital349:
Definitely try ASV level 7 first and then if you have problems, work your way down the levels until you find the one that works perfectly. 7, 6, 5, etc.

Glad you have it sorted. :)
[Galaxy S II General] banok:
Does hydra have a profiles setting like cm9? I like it because I can turn on/off many things (wifi, 3g, gps, Bluetooth, vibration) and set many volume levels in just one click.

Then leaving home to walk in the street, or when I get to work, or get in the car to use gps maps... It's really a breeze.

And after 4 days of usage in the same nightly, finally cm9 is having a good battery life with neak. I think I'll just update on a weekly basis to get more days on a stable battery life.

Or... If any of you guys can sell me the hydra ROM... Let's see...

I'm on lvl5 now. With 6 my Google Talk video chat allways freeze xD
[Galaxy S II General] Kaizneight:
ok..i tried from level 6 to Level 7, but cannot get into home screen..hang straight away...so yes...Level 6 is probably my best choice..I turned it down to level 6, and got it well again..LOL

Edit: after I reup the AVS from 7 and down to Level 6, got the previous problem again, So i have to reflash kernel while deleting old settings and set the ASV to level 7 after reinstalling kernel and before restarting..and it works wonder...for now..i haven't tried using all apps available in my S2...but should there be any problem, i will report it again XD
[Galaxy S II General] hospital349:
You don't have to reflash or anything. Just reselect the new level until you feel your device is stable. A lot of people are sticking with Level 5, so it may be the level for you. Give it a try.
[Galaxy S II General] Kaizneight:
lol...reply a bit late XD..already reflashing...oh well...yes, currently i am sticking to level 5...hopefully it is as stable as everyone else XD
[Galaxy S II General] hospital349:
...and not one 'Thank' was given that day.
[Galaxy S II General] Kaizneight:
lol..don't worry..i gave it already XD..thanks for the help, again XD

---------- Post added at 02:02 AM ---------- Previous post was at 01:23 AM ----------

btw, i forgot to mention...I tried changing the level after the S2 became hang (lvl 7 to lvl 6 and lvl 6 to lvl 5) , but gave same result, which is why I decided to reflash and redelete+reconfig all settings..maybe my S2 is the most weird among all the user trying the undervolting *shrugs
[Galaxy S II General] hospital349:
That's the weirdest thing bro. I think you might be the only one. :rolleyes:

There are some other settings (from WIN!UV v1.0) - these might work for you and they'll give great battery life. People swore by them. Give them a try if you fancy it:

[Galaxy S II General] hospital349:
Absolutely devistated

My girlfriend charged my phone up whilst I was downstairs eating my food this evening. Battery stats = wiped :eek:

I will be performing this test again. I was on approx 6hrs 45 mins screen time, 1 day and 12 hours battery time, with 20% battery left. Guttered. Nevertheless, anybody who uses these settings will witness the difference first hand.

Another two days from now you'll have my visual verdict. Until then, feel free to post any stats that raise the roof! :)
[Galaxy S II General] msquared:
Wich of the first page settings can we obtain with the free app?

And with those settings did u expected lag or rallenties etc etc.. ?

Thanks for the answer mate ;)
[Galaxy S II General] hospital349:
I have absolutely no idea, as I purchased the Pro app straight away. You're better off asking Simone about it on the N.E.A.K. thread.

Feel comforted in knowing that even though you are going to be dramatically saving battery, performance won't be effected. As always, I would recommend you using a kernel cleaner if you're coming from a different kernel. Other than that, if you set ASV busfreq to Level 7 and you have issues, try 6, issues again? - try 5 and so on.

I'm actually looking at adjusting the settings shortly, as long as the ones that I'm testing now has a better effect on battery life (which I think they might).

Have fun. Battery life is great with WIN!UV. :)
[Galaxy S II General] tariq2kn:
Is it possible to charge the battery at 1Ampere instead of 650 mAh?
[Galaxy S II General] simone201:
The S2 supports only 450 and 650mA
[Galaxy S II General] :
Thumps up for this thread :D :D
[Galaxy S II General] m4x0r:
Where can i see what Level i'm using atm?

I think it worked now with level7 after reflashing it neak
[Galaxy S II General] :
Sorry didn't check the thread for a few days! I'm on the latest CM9 nightly and it's fantastic. I'm very minimalist and CM9 pretty much gets the job done. But I did notice that Hydrogen seems to get a bit more battery, although I can't figure out why. CM9 is supposedly more "clean" compared to the other AOKP/AOSP ones... I'll test it out a bit more and give you more detailed results!

I think in terms of the "finish" is very important to me. I remember there were parts of Resurrection Rom in which I used that bugged me a lot. (Some toggles not working as it should). It simply made the phone not feel very "complete" -- like it's a work in progress sort of deal. In CM9 my 2G toggle works! Helps with battery saving when I need it during my late night escapades. :p

I felt the exact same too! I loved Hydrogen and don't really like change, and was super sad when they discontinued support for it. But I think I'll follow in your footsteps and try out this one you're using.

Seems like you've settled down on a rom, keep us updated please!
[Galaxy S II General] msquared:
Thx for the answer mate... i've seen that i can reach the first page settings using the free app and voltage control at the sa me time.. do u think there will be a contrast between the two apps?

Cheers ;)
[Galaxy S II General] hospital349:
Thanks for your responses. I decided not to quote everything, for obvious reasons. :p

I'm glad many of us were able to move on from our HyDroG3N-ICS experiences as swiftly as possible. I definitely didn't want to be riding its wave any longer than necessary.

I have now tried CM9, Hydra & Paranoid Android and came to the conclusion that perhaps there was something missing from CM9; most probably the AOKP features. You're definitely correct though... I think I would prefer a ROM to run perfectly minus all the frills, than have something that seems too buggy, with too many useless-extra features. I think that's why I enjoyed using CM9 as much as I did. It isn't trying to be anything else other than a simple base ROM that works well, without all of the frustrations that come with many AOKP ROMS.

I'll definitely keep you updated.

Keep a look out for a settings update shortly.

v2.1 is on its way. :)
[Galaxy S II General] hospital349:
Possibly not; as long as you only tick 'set on boot' and apply for the app you want to control those specific tasks. If you get me... (For instance; don't let both apps control your CPU voltages as they would clash... just select one to perform each task category.)

If you do have any issues, again just go back into recovery mode and return your settings to default. Also, I think Voltage Control has a feature where it gives you 10 seconds to cancel your settings before it applies them upon boot, so that's another safeguard for you. :)

EDIT: Actually come to think of it... I'm not so sure that you can use Voltage Control in such a way. I think if you ask it to 'set on boot' - it controls EVERYTHING by default and that cannot be changed. This may cause the two apps to clash... I'm not sure. Probably best to just purchase the N.E.A.K. Configurator Pro app in the long run. You really won't regret it. The decision is yours.
[Galaxy S II General] Dunki3:
For me, CM9 all the way. Tested all and nothing is like CM9 :)

Can't wait you new settings. :p
[Galaxy S II General] msquared:
Thx again for the clear answer mate...last question :

I'm actually running CM9 do u think that ur settings are going to work good on it because it's an AOSP like Hydra or something could change??
[Galaxy S II General] hospital349:
No probs. :)

Settings tested on CM9, working just fine. I flashed it a few days back, no issues at all. Great battery life.
[Galaxy S II General] msquared:
Cheers mate as soon as the battery get charged i'm going to try them ;)
[Galaxy S II General] hospital349:
You won't regret it.

Enjoy! :D
[Galaxy S II General] Dunki3:
I'm using this settings in CM9 and everything is ok.
[Galaxy S II General] ata1918:
Great even more UV configs to test out :D

Cheers !

Sent from my GT-I9100
[Galaxy S II General] hospital349:
Simone has kindly asked me to test 2.0.6x. You are not going to be disappointed.

I only flashed a couple of hours ago and improvements are clearly noticeable. I'm using WIN!UV v2.1 settings (unreleased until tests are complete ;)) and I'm getting 1% battery drop with 15 minutes of music (played through phone speaker on high volume), with the screen on. I've browsed using Chrome for 10 minutes, again with only 1% battery drop. Best kernel... EVAAAAAAHHH!!
[Galaxy S II General] hospital349:
More on 2.0.6x:

Disbelieving my battery stats...

14 minutes on GTA3 = 2% battery decrease.

UNREAL!!
[Galaxy S II General] :
Wow thats unbelievable :D
[Galaxy S II General] :
I love Hydra... Just switched over and it is actually quite polished in terms of the overall usability. I quite like it. It's really between this one and CM9 for me. Thanks for the suggestion! I think I'll be keeping this ROM for awhile. :cool:

hospital349, just wondering, do you use messaging applications such as whatsapp? These apps are quite battery drainers...
[Galaxy S II General] dbanzon:
just switched to hydro-h20 rom to try out your uv settings. So far liking it!
[Galaxy S II General] max.android:
wow..awesome battery stats :)
[Galaxy S II General] hospital349:
I'm glad you're both enjoying the wonders of N.E.A.K.

There's more goodies coming soon :)

Hey alexy,

I don't use other messaging applications for that reason. I got unlimited free texts messaging on my network so I never found a need to use such apps. I even switched from Facebook app to Friendcaster because of the amount of battery drain the official Facebook app caused. I do feel your pain.

I suppose 2.0.6x will help with this issue, as at least the drain will be less because the UV and overall build of the update kernel is better. :)
[Galaxy S II General] AllSeeyinEye:
Whatsapp isn't quite that battery drainer. Exchange is. Pitty I'm stuck with it, since it is my business phone...

It's time an exchange.apk is released that is actually optimized. No matter the settings you make, syncing will always take place, regardless if you marked once an hour or never etc.
[Galaxy S II General] hospital349:
+1.

I couldn't agree more. I find that syncing is one of the biggest culprits of wakelocking & thus drain. It's a real annoyance and I really wish that I didn't need to rely on app syncing as much as I do. Unfortunately, it's an integral factor of most smartphones these days. Completely unavoidable.
