I already heard about this app ... in GB days.

You can check if the UV is applied correctly with CPU Adjuster or Voltage Control app.
[Galaxy S II General] pedestre:
I tested it in GB days and I think it worked (UV) but I could check that It drained more battery than it saved with UV.

I haven't used in ICS nor JB ( I undervolted by myself)
[Galaxy S II General] egps2:
Hi again Many40 :)

Unfortunately I can't confirm using other apps because apps like "voltage control" which do need kernel support don't show the voltage tab but voltage control and setcpu both show that I can overclock using Tegrak and shows improvements to benchmark scores but the only personal proof I have for UV is the big drop in temperature when gaming etc.

EDIT: I have confirmed that Tegrak can undervolt on custom kernels (using other apps to verify) but since these apps don't work on stock kernel I can't use them to verify that tegrak works so sorry about that. Like I posted above, it is featured on the XDA website and forum moderators have confirmed it working as have other members :)

PhilZ v5.06.6:

Good battery life in night use.

PhilZ v5.06.6 (XWLSW NeatROM Lite v4.8): Battery loss of 0,55% per hour, Awake: 1,8%

Hope that I can finish my mixed usage battery test today.

EDIT:

I tried Tegrak and it won't even load the module on Philz, says its not supported by kernel:confused:

★NeatROM★ Mods ___________Battery Tips
[Galaxy S II General] egps2:
I simply installed NeatROM 4.8 and am using the version of PhilZ included in the Zip and to be clear I am using the paid version which a bought back in GB days and don't know if the free version still works as I only tested it on GB. Here are some screenshots I just took showing the settings I'm currently playing with and a screenshot from system settings. I read that on the play store some people were having problems loading the module and with licence checks not working but I appear to be running the same set-up as you which is strange.
[Galaxy S II General] egps2:
Some more screenshots of Tegrak Ultimate on stock NeatROM Lite 4.8 with PhilZ as included :)

Edit: Sorry please merge double post, thank you.

Ps I'm not saying anyone should buy this app, I only got it ages ago when I wasn't comfortable using custom kernels and I hardly used it when I was using Siyah kernel but only started using it again on JB when I didn't feel like using the then unstable custom kernels. After my exams I'll probably uninstall it and use Apolo. Also, it doesn't seem to load for some people so I definitely would not risk buying it but test out the free version to see if it'll overclock if you're curious. I only really mentioned this app because people were telling me it's not possible to undervolt on PhilZ/stock and wanted to share it as an option for anyone curious as to how I did it.

Summary: works for me, not for everyone and probably not worth buying but feel free to test free version if you're bored or curious :)

PhilZ v5.06.6:

Good battery life in mixed usage too.

PhilZ v5.06.6 (XWLSW NeatROM Lite v4.8): Battery loss of 1,32% per hour, Wifi: 10,2%, Awake: 11,7%, Screen: 10,1% => loss*(1-screen): 1,19%

It's exactly the same battery life like on XWLSW NeatROM Lite v4.8 with default PhilZ kernel (v5.06.1).

So my system is very stable ATM.

Here are some screenshots:
[Galaxy S II General] It_ler:
Apolo v4.7:

I just flashed Apolo kernel v4.7 light on my XWLSW NeatROM Lite v4.8.

It is very stable and smooth on my phone.

Everything works fine ... except of the battery charging animation when turning phone off while plugged into charger.

Light version with light volatges and competely default kernel settings.

First result on AnTuTu: Apolo v4.7 (XWLSW NeatROM Lite v4.8): 9389

Now preparing battery tests.
[Galaxy S II General] It_ler:
Apolo v4.7:

Very good battery life in night use.

Apolo v4.7 light (XWLSW NeatROM Lite v4.8): Battery loss of 0,48% per hour, Awake: 1,7%

It's a little bit worse than on my best run for XWLSS, but still very good.

Let's check its battery life in mixed usage now.

EDIT:

Added some screenshots:
[Galaxy S II General] a1adin:
I have used apolo v4.6 regular for 2 days,

now I am using apolo v4.7 regular.

It seems to me that v4.6 has better battery life

Anyone has the same experience?

I am using neatrom v4.7.
[Galaxy S II General] It_ler:
Looking into the changelog of the kernel, there should be nearly no difference in battery life ... except for extensive wifi usage.

Maybe the system needs so time to settle down completely to show better battery life on v4.7 too?!

EDIT:

Apolo kernel changelog from v4.6 > v4.7:

- New Wifi Drivers from S4 (Thx dorimanx and codeworks)

- Added I/O Scheduler row (Thx Jeboo)
[Galaxy S II General] It_ler:
Apolo v4.7:

Very good battery life in mixed usage too.

Apolo v4.7 light (XWLSW NeatROM Lite v4.8): Battery loss of 1,29% per hour, Wifi: 10,5%, Awake: 11,9%, Screen: 10,5% => loss*(1-screen): 1,15%

But it's again a little bit worse than the best result for v4.7 on XWLSS.

I think I will check my results on a second cycle.

Here are some screenshots:
[Galaxy S II General] It_ler:
Re-test Apolo v4.7:

Nearly the same battery life on second run in mixed usage battery test.

Apolo v4.7 light (XWLSW NeatROM Lite v4.8): Battery loss of 1,28% per hour, Wifi: 10,2%, Awake: 11,8%, Screen: 10,1% => loss*(1-screen): 1,15%

Although the battery life in night use was worse than on first run.

Maybe a third run will lead to better battery life, but it seems that Apolo v4.7 light works better with XWLSS on my phone.

Here are some screenshots:
[Galaxy S II General] mathmachado:
Same here, since I've switched to from neatrom 4.7 to 4.8 I'm getting slighty worse results on mixed and night usage.

Nevertheless, I'm still having an awesome battery life :)
[Galaxy S II General] championc:
Sorry, I know it's been said pages and pages back but which Governor and I/O scheduler are you using ?
[Galaxy S II General] It_ler:
Correct ... stated it several times before: I am using the kernel's default settings.

So kernel's default scheduler and governor - unchanged.

If I change it, I will explicitly specify it when posting my results.

ATM I'm on Apolo v4.7 light ... haven't even checked its scheduler and governor ... I think it is cfq and ondemand ... but I'm not sure as it was cfq and slp on v4.6 light.

EDIT:

Checked now. On Apolo v4.7 light, the default io scheduler is cfq and the default CPU governor is ondemand.

Will check again with cfq and slp, as these were the defaults on v4.6 light.

But I think the combination of ROM with kernel has a bigger effect on the battery life ... let's see.
[Galaxy S II General] GoldGanja:
Ops i did it again

Hello!

Re-retest Apolo v4.7:

With cfq/slp, the battery life in nigh tuse was worse.

Apolo v4.7 light (XWLSW NeatROM Lite v4.8, cfq/slp): Battery loss of 0,59% per hour, Awake: 1,5%

But in mixed usage, it was slightly better compared to default cfq/ondemand.

Apolo v4.7 light (XWLSW NeatROM Lite v4.8, cfq/slp): Battery loss of 1,25% per hour, Wifi: 9,9%, Awake: 11,2%, Screen: 9,8% => loss*(1-screen): 1,13%

thanks it_ler your thread is very good, I learned a lot here
[Galaxy S II General] It_ler:
You want to buy my phone :confused:

No, no, I still like it.

To optimize your battery life, I recommend to install and use Better Battery Stats (BBS).

If you are rooted, enable root options in Advanced and tick all stats in Dumpfile menu.

Then record an idle dump (doing nothing / screen off all the time) for about 4 hours, and post it as an attachment in BBS thread.

Good luck !

Re-Test PhilZ v5.06.6:

I just flashed again PhilZ-touch kernel v5.06.6 on my XWLSW NeatROM Lite v4.8.

Want to check if my system is still "stable" after many app updates.

Good battery life in night use:

PhilZ v5.06.6 (XWLSW NeatROM Lite v4.8): Battery loss of 0,56% per hour, Awake: 1,6%

It's nearly the same as before - was 0,55% per hour.

So my system seems to be stable. Will also check check in mixed usage before processing with new kernel tests.

EDIT:

SiyahKernel v6.0b5:

I just flashed SiyahKernel v6.0b5 on my XWLSW NeatROM Lite v4.8.

It is very stable and smooth on my phone ... good old SiyahKernel.

Everything seems to work fine so far (custom boot animation, wifi, bluetooth, GPS, camera, video recording, Gallery, live thumbnails in video player, fm radio, etc.).

I just want to see, if my system works fine with this kernel ... and will update SiyahKernel results in first post.

Everything is on default settings ... except the CPU governor. I changed to pegasusq, as I had better battery life with this governor (compared to the default = ondemand) in previous tests.

Siyah v6.0b5 (XWLSW NeatROM Lite v4.8, Pegasusq): Battery loss of 0,56% per hour, Awake: 2,2%

It's a little bit worse than on previous NeatROM Lite versions, but still OK.

Battery life in mixed usage seems to be worse ... let's check it.

[Galaxy S II General] ciprigeorgiu:
Hello It-ler. THought I will post my question in your thread: I am on NeatRom 4,7 (LSS). Would it be bad if I flash latest Philz kernel which is for LSW base? or it only works well if it's flashed on to on Nearom 4,8?
[Galaxy S II General] It_ler:
It will probably work fine, as there is not much difference in the kernel between the two stock ROM versions.

Create a nandroid backup first. So if you experience some issues, boot into recovery and restore the backup.

Good luck !
[Galaxy S II General] It_ler:
Siyah v6.0b5:

It is stable and smooth on my phone.

Everything seems to work fine so far (custom boot animation, wifi, bluetooth, GPS, camera, video recording, Gallery, live thumbnails in video player, etc.).

Subjectively it has a little bit darker screen when using the lowest system brightness.

I am still on completely default kernel settings.

CWM in English looks good ... I like it.

EDIT:

EFS backup on external sd card seems not to work as expected.

Will try again on internal sd card and report back.

BTW, first AnTuTu result: 9342.

EDIT2:

No, EFS backup doesn't work properly.

Neither on external nor on internal sd card.

But battery charging animation seems to work fine, even after turning off the phone while plugged into charger.
[Galaxy S II General] mr_zuff:
It's not you man! ;)

Brightness has been set lower than normal, but only when you use manual mode. In "Auto", brightness it's the same as older versions :)
[Galaxy S II General] It_ler:
Yes, read some posts about it already.

As I am always using manual mode, I can easily adjust the brightness to the level I want/need.

So it's not a "real" issue. I just wanted to confirm this "feature".

EDIT:

BTW, second result on AnTuTu: Apolo v4.8 (XWLSW NeatROM Lite v4.8): 9837

Apolo v4.8:

Moderate battery life in night use.

Apolo v4.8 light (XWLSW NeatROM Lite v4.8): Battery loss of 0,61% per hour, Awake: 2,1%

It's a little bit worse than for Apolo v4.7 light on same ROM.

Maybe I have to re-do my battery test, as there were some additional wakelocks (caused by my antivirus app).

Here are some screenshots:

But a little bit worse than for stock / PhilZ kernel and significantly worse than for v4.7 on XWLSS.

Oh ... I found a difference: In my antivirus app, network stats were enabled. That could be the cause of the wakelocks and alarms of this app.

I will re-do the battery tests ... on v4.8b.

The only problem with antutu is that you can get 10400 score and one minute later only 9900. And I did a lot of testing with it using the same rom kernel combination. So it is not the best tool to rely on.

IMHO.

Anyway the battery results are mote usefull.

Thanks
[Galaxy S II General] It_ler:
Yes, I have tested a lot of benchmark apps. But all of them have disadvantages.

Maybe sometime, there will be a good benchmark app which can give reliable results.

Just let me know and I will check it ;)

As I am more keen on the battery tests, I don't want to spend much time in searching and testing benchmark apps.

I list AnTuTu results only to have something more than the subjective feeling of the kernels smoothness.

But it's only numbers ... :p

Re-test Apolo v4.8b:

Fantastic battery life in night use on the second battery cycle.

Apolo v4.8b light (XWLSW NeatROM Lite v4.8): Battery loss of 0,42% per hour, Awake: 1,9%

It's not a new "record" on my phone, but best battery life on XWLSW so far. And it's still light version with light voltages settings.

So this kernel really needs some time to settle down and achieve its best battery life.

Here are some screenshots:

Re-test Apolo v4.8b:

Unbelievable battery life in mixed usage.

That is a new "record" on my phone.

I think it's because of the lower brightness of the screen for manual brightness - I am using lowest level, and it is a little bit lower than stock on this kernel.

Here are some screenshots:
[Galaxy S II General] umair42:

Thanks, but keep in mind, that my usage is very light.

With more internet browsing, phone calls, SMS, Emails, gaming, etc. my battery life would be significantly worse.

It's not my aim to "break" someone's results.

But I am sure that you already know it.

I just want to find the best balanced kernel/ROM combination for stablility, battery life and performance.

And I'm very happy with my current combo :D:fingers-crossed:
[Galaxy S II General] It_ler:
I tried the balanced profile, but could not recognize better battery life.

Maybe it was slightly smoother - subjective feeling ... could be placebo too :rolleyes:

But battery life in night use on balance profile was a little bit worse than on my last run with default (light) settings.

Seems to be the best configuration for my light usage :good:
[Galaxy S II General] peron:
Hello IT_ler, great job you are doing here.

Could I suggests to add on the first page that all your tests are with the lowest brightness and ideally could you add tests with max brightness?
[Galaxy S II General] It_ler:
It's already in FAQ section of post #2:

Question: What are your settings for better battery life?

Answer:

Have a look at this tips collection => http://xdaforums.com/show...php?p=16973603

Nothing more to add.

I disabled all location services, auto-sync, bluetooth, set to lowest brightness, use a black background, disabled some system apps (such as Social Hub, Games Hub, Music Hub, Samsung Hub, Google+, BBC, Zinio, etc.).

...​

And I like lowest brightness - except when outdoors and sun is shining.

So I won't run a battery test with maximum brightness.

If you want to compare battery life with different brightness levels, feel free to post your results here.

[Galaxy S II General] Donnie Sins:
I always use Speedmod kernel. I did try Chameleon for a long time, and it is totally stable, but battery life seems to be less good than on Neatrom (which I'm using right now with Speedmod). About 30 min. to an hour difference in screen time, and deep sleep was a little worse.

Would be interesting if other people have noticed different results.

Nice battery life again with auto brigtness couple of calls, messenger viber, browsing, and exam cheating :D Using Apollo Light 4.8 kernel.
[Galaxy S II General] raul_18:
It_ler, can you tell us whar gobernador and programator are you using? for your battery result? and voltages?

thanks
[Galaxy S II General] It_ler:
I hope that I have understood you correctly.

As I am on Apolo v4.8b light, I am using the kernel's default CPU governor (ondemand) and IO scheduler (cfq).

As my phone only works stable with light version and voltages, I also have the default light voltages ... unchanged.

So nothing special - just kernel default values/settings.

I think the key to good battery life is not only to flash a good ROM and/or kernel, but to check system settings (disable everything you don't really need) and minimize all unwanted wakelocks/alarms.

That's why I am always checking my battery stats in BBS app.
