{Off topic}

I bought the samsung note 3, I'm happy with battery life 7hrs screentime but I continue with my s2. what will be the new mobile? sammy S5, nexus 5, iphone 5s, IgG2 or Note 3?
[Galaxy S II General] It_ler:
Hmm ... Note 3 is nice ... but very large IMO.

I like Android ... and the SGS2 is still a powerful device. So I think that I will keep it for a while.

And if I feel the need to update to the current OS version, I have the option to flash a custom ROM ... at least some developers are still supporting this "old" smartphone ... fortunately :fingers-crossed:

Re-test Apolo v4.13 (Regular):

Finally my retest for Apolo v4.13 (Regualr) kernel on my XWMS1 NeatROM v5.4.2 Aroma/Lite.

Apolo v4.13 regular (XWMS1 NeatROM Lite v5.4.2): Battery loss of 1,11% per hour, Wifi: 10,1%, Awake: 11,2%, Screen: 10,0% => loss*(1-screen): 1,0%

Now it's similar than the best results of previous kernel versions ... excellent :good:

My system and my battery are still stable an in good shape :fingers-crossed:

Well the answer might be hidden in the title of this thread ;):D
[Galaxy S II General] umair42:
Oh my bad ;)
[Galaxy S II General] It_ler:
Well ... not yet.

As long as I don't feel "forced" to leave stock / Sammy based ROMs, I won't flash a custom ROM.

But if, then I will surely consider AOSP NeatROM.

Yes, you are right.

Any tests on custom ROMs would need a separate thread ... or I would have to change the title of this thread ;)

[Galaxy S II General] It_ler:
XWMS2 NeatROM v5.6 Aroma:

I just flashed XWMS2 NeatROM v5.6 Aroma (Lite) to my phone.

It is very stable and very smooth, everything works fine.

First run on AnTuTu directly after flashing: NeatROM XWMS2: 10413.

Will run battery tests on stock/PhilZ kernel first before flashing another kernel.
[Galaxy S II General] It_ler:
Second run on AnTuTu: NeatROM XWMS2: 10564

[Galaxy S II General] It_ler:
XWMS2 NeatROM v5.6:

Good battery life in night use.

NeatROM XWMS2 (v5.6): Battery loss of 0,51% per hour, Awake: 1,1%

Deep sleep ratio was fantastic, so maybe battery life will be a little bit better on second battery cycle.

EDIT:

Added a screenshot:
[Galaxy S II General] It_ler:
XWMS2 NeatROM v5.6:

Moderate battery life in mixed usage.

NeatROM XWMS2: Battery loss of 1,49% per hour, Wifi: 9,8%, Awake: 10,7%, Screen: 9,7% => loss*(1-screen): 1,35%

It's worse than for many other NeatROM version. But htis was on first battery cycle.

So maybe the battery stats chip was not settled down properly.

I will repeat the battery tests and post the updates soon.

Here are some screenshots:
[Galaxy S II General] It_ler:
Retest XWMS2 NeatROM v5.6:

Slightly better battery life in second battery cycle.

NeatROM XWMS2: Battery loss of 0,48% per hour, Awake: 1,2%

It's similar to other ROM versions now, but still a little bit worse than for XWMS1 based NeatROM versions.

Let's wait for the mixed usage battery "re"-test result.

EDIT:

Added some screenshots:
[Galaxy S II General] It_ler:
Retest XWMS2 NeatROM v5.6:

Slightly worse battery life in mixed usage on second battery cycle.

NeatROM XWMS2: Battery loss of 1,52% per hour, Wifi: 10,2%, Awake: 11,1%, Screen: 10,1% => loss*(1-screen): 1,37%

Will check all my settings, if there was a change ... GSF wakelocks seem to be a little bit higher than on my previous installation.

Here are some screenshots:
[Galaxy S II General] It_ler:
Yes, I found 2 - 3 autostarts of GSF in System Tuner app that should be disabled but were enabled.

I have now disabled those GSF autostarts again and rebooted.

Let me repeat the battery tests once again (maybe tomorrow) to verify if these autostarts were the cause of the additional GSF wakelocks and battery life might be better.
[Galaxy S II General] It_ler:
Re-retest XWMS2 NeatROM v5.6:

Excellent battery life in night use on third battery cycle.

NeatROM XWMS2: Battery loss of 0,37% per hour, Awake: 0,8%

And fantastic deep sleep ratio of about 99,2% !

So it seems that the higher battery consumption was caused by the 2 - 3 autostarts of GSF I missed to disable before.

Let's check battery life in mixed usage before voting on this ROM.

EDIT:

Added some screenshots:
[Galaxy S II General] It_ler:
Re-retest XWMS2 NeatROM v5.6:

NeatROM XWMS2: Battery loss of 1,54% per hour, Wifi: 10,3%, Awake: 11,0%, Screen: 10,2% => loss*(1-screen): 1,38%

There was a high SyncLoopWakeLock ... although I have disabled all account synchronizations :confused:

I hope that it's only a temporarily and not a systematical issue ... caused by too many disabled autostarts of GSF and Google Play Service :D

Here are some screenshots:
[Galaxy S II General] It_ler:
Apolo v4.13 (Regular) on XWMS2:

I flashed Apolo v4.13 (Regular) with English CWM recovery on my XWMS2 NeatROM v5.6 ROM.

It is very stable and very smooth on my phone.

Everything works fine.

Still had some SyncLoopWakeLocks. So I enabled Auto-Sync option, checked all accounts, and disabled Auto-Sync option again.

Now the SyncLoopWakeLock seems to be "normal" again.

Excellent battery life in night use.

Apolo v4.13 regular (XWMS2 NeatROM Lite v5.6): Battery loss of 0,35% per hour, Awake: 1,0%

It's nearly the same as for same kernel on my previous ROM (XWMS1 NeatROM v5.4.2), but with a slightly better deep sleep ratio of about 99%.

Now I am checking its battery life in mixed usage.

EDIT:

Added some screenshots:
[Galaxy S II General] It_ler:
Apolo v4.13 (Regular) on XWMS2:

Fantastic battery life in mixed usage.

This is the best battery life I've ever had in mixed usage battery test so far.

I will check that this battery values are stable.

Here are some screenshots:
[Galaxy S II General] It_ler:
Apolo v4.13 (Regular) on XWMS2:

First run on AnTuTu after the battery tests: Apolo v4.13 (XWMS2 NeatROM Lite v5.6): 11117

Best value on my phone so far.

Now I don't regret to have flashed XWMS2 based NeatROM v5.6 ;)

Here the proof:
[Galaxy S II General] umair42:
Why your battery graph goes up after some time?
[Galaxy S II General] Many40:
This is IMO how a sophisticated fuel gauge chip built into S2 tracks/estimates in real time battery relative state of charge. It could be that during bigger battery usage (when WIFI was on and screen on) it underestimated the battery level and some time after, it corrected a little bit the reading....
[Galaxy S II General] Hopper8:
Do you use a "checklist" or something of the GSF or GPlay services parts to disable? I also disable a lot of things out of these two using System Tuner. However, as your battery life is stellar, I'd like to know which specific ones you disable, if it's not too much trouble? :good: :highfive:
[Galaxy S II General] It_ler:
Yes, I followed Karpfenhai's and Casanoaa's instructions to disable some autostarts for Maps, GSF and Google Play Service.

And remember: Disabling too many autostarts may have the opposite effect on your battery life by causing massive wakelocks.
[Galaxy S II General] Hopper8:
Awesome! I'll definitely set up according to that, thanks a lot :D

[Galaxy S II General] It_ler:

What about this kernel: http://www.androidfilehost.com/?fid=23329332407570354

It was released by gustavo_s, parallel to his KitKat Kernel.

Do you think it will boot on your ROM and you can check it?

I don't know if it will work under JB stock, otherwise we have to wait until you will flash a custom rom ;)

Here is the concerning kernel thread:

[Galaxy S II General] Many40:
AFAIK it's for AOSP based JB roms (CM10.2) and not stock samsung based roms (JB 4.1.2) which are used by It_ler on this thread.
[Galaxy S II General] It_ler:
Only for custom ROMs. But I will consider it as soon as I leave stock ROMs.

So not for now.

best bettery life

Hi Guys,

im new in this topic. Would you recommend to install the neatrom + apolo regular kernel like the guy, whos was using s2 for 7 days without charging.

Or you say, better to install everything in light or ultralight version, then the device will use less enegry as by regular?

Please help me.
[Galaxy S II General] @Existence@:
Also the new Galaxian Kernel, is built of 4.0.4 sources. So no camera or bluetooth fix needed to enjoy camera and bluetooth with this kernel!

Kernel is highly recommended, the dev is famous from I9100...
[Galaxy S II General] It_ler:
Thanks for your suggestion.

I have added this kernel to my "kernels-to-test" list in post #2.

[Galaxy S II General] jlevy73:
Mixed usage with hardcore k3-30 is good for me. About 1.8%/hour loss.
[Galaxy S II General] It_ler:
SpeedMod K3-30:

In mixed usage, it has worse battery life than stock kernel.

SpeedMod K3-30: Battery loss of 1,97% per hour, Wifi: 100%, Awake: 17,3%, Deep sleep: 82%, Screen: 11,0% => loss*(1-screen): 1,75%

It's OK, but not very good IMO.
[Galaxy S II General] PholkLorr:
Can you test the Dark Knight kernel (currently v 1.9.2)? Supposed to be very battery friendly

Thanks
[Galaxy S II General] It_ler:
Is already on my kernels-to-test list.
[Galaxy S II General] It_ler:
Hiro.30 (Phenomenal) Extreme:

Stuck at bootlogo.

Came from SpeedMod K3-30 and flashed with Mobile Odin app.

Flashed with Odin ... still stuck at boot logo.

No recovery mode, only download mode.

Trying to fix it with Intensive version.

Now recovery mode works, but still boot loops.

Try to wipe cache and Dalvik cache and fix permissions in recovery, but seems to hang while fixing permissions ...

Where is my last nandroid backup for restoring?!

Now restorig my last nandroid backup of stock XWLPO.

Then I will decide what to do next. (Another try for hiro/Phenomenal or skip this version?!)

Phone hangs while restoring data.

Reboot normally to "virgin" system (seems to be wiped data).

But there is CWM recovery of CF-Root I think.

Try to restore the nandroid backup again.

Restoring data seems to work now.

Restoring of nanadroid backup was successful now.

Back on stock XWLPO with CF-Root v5.6 for XXLQ5 kernel.

Need some time to get prepared for next kernel test.

Maybe I will skip this Hiro/Phenomenal version.
[Galaxy S II General] drakexpl:
Hiro phenomenal intensive based on k3-30 here. Stable like a rock, heavy use with wifi hotspot on. So it's not kernel related.

I'm on Deodexed XWLPO by Wanamlite, then I flashed K3-30 intensive throught ODIN and wiped cache and dalvik @ CWM - all brilliant. ; - )
[Galaxy S II General] It_ler:
XWLPT:

I just flashed stock XWLPT ROM with CF-Root v5.6 for XXLQ5 kernel with Mobile Odin app.

Everything seems to work fine.

Local search is back, serial number still 00000000, some new games, some new system app versions, rest similar to XWLPM and XWLPO ROMs.

Brightness sliding in status bar doesn not work ... also same as for XWLPO.

GPS, wifi, Bluethooth, camera ... everything I tested so far works just fine.
[Galaxy S II General] jackrip5:
This time I'll wait with updating until you say it's really worth it. As i said before, there are lots of new roms the last days. I like the lpo because it's clean of bloatware.

Nevertheless if you should find an upcoming rom with better results I'll update again.

Why did you ditch Siyah kernel? I used to visit this thread every few days, but not since you abandoned the most powerful kernel of all times.
[Galaxy S II General] It_ler:
Not ditched and not abandoned SiyahKernel.

As there is a "slower" development, I focused more on searching and finding a new base ROM the last few weeks.

That will give all kernel devs more time to adapt to new Android 4.0.4 stock ROMs ... and JellyBean.

SiyahKernel is still on my kernels-to-test list ... just have a look on post #2.

I have not removed it.

But first I want to find a stable and good base ROM before continuing further custom kernel tests.
[Galaxy S II General] It_ler:
Bloatware apps ... games can be uninstalled and system apps can be deactivated.

I think XWLPM also had a lot of Russian boatware.

One time action to go through the list of apps in Settings > Applications > All and clean up what you don't want.

Doesn't take much time ... about one minute if you know what to look for.

Before starting my tests, I want to charge the battery and let it settle.

So it might take some time before updating the OP with XWLPT test results.
[Galaxy S II General] jackrip5:
That's true, i use titanium backup for this... But you know human is a bit lazy ;)

XWLPT:

Benchmark results added to OP.

Feels as smooth as XWLPM and XWLPO ... no significant difference.

Could be caused by using the same CF-Root kernel.

Maybe I will repeat some tests with stock XWLPT kernel.
[Galaxy S II General] DanDroidian:
I have always used this and will miss it if I have to change to a rom that doesn't have it.

Can I still activate it using Apex Launcher, JKay, or another way?
[Galaxy S II General] It_ler:
Are you talking about NeatROM full / lite / ultra lite, or about Apolo light / regular / extreme?

Latest NeatROM versions are provided as AROMA, so you can choose during installation about what you want to install.

This is about more or less apps, which ma lead to more or less activity on your phone and therefore to more or less battery consumption.

I am using Lite installation version, as I still have al apps I need/want, but most of the unwanted bloatware is removed.

The different version of Apolo kernel have different voltages. Sequence from higher to lower voltages is: Light > Regular > Extreme.

As long as your phone and all apps/services are running stable with some undervolting, less voltage lead to less battery consumption.

But as soon as your system becomes unstable (which is different on different phones), the battery consumption may increase again.

So you have to find the "best" kernel version (or voltages) for your phone.

I can only use Light and Regular versions, as my phone is not able to run stable with Extreme versions of this kernel.

As Regular has a little lower voltages than Light version, I prefer Apolo Regular versions.
[Galaxy S II General] damianino:
thanks for your fast answer, i understand now :) so I'm beginning now to install it, because CM 10.2 (Android 4.3.1) + 3.0.64 CM kernel make my battery incredible fast empty.

---------- Post added at 11:19 AM ---------- Previous post was at 11:07 AM ----------

dear lt_ler, last question: what prefer you in the reason of kernel.. CWM or TWRP by this ROM ?
[Galaxy S II General] It_ler:
I prefer English CWM version of this kernel, as I am used to CWM recovery.

But TWRP recovery is also fine.

And I think this will be the future recovery version for Apolo kernels anyway.

So it's just a matter of personal preferences.
[Galaxy S II General] It_ler:
Apolo v4.13 (regular) on XWMS3 NeatROM v5.8 Aroma:

I have flashed latest XWMS3 NeatROM v5.8 Aroma with Apolo v4.13 regular.

It is stable and smooth on my phone.

Everything is woking fine ... I just had to update SuperSU app manually from Play store, as Apolo kernel has overwritten the latest version from the ROM with an older one.

First run on AnTuTu: Apolo v4.13 (XWMS3 NeatROM v5.8): 10824

And an excellent battery life in first battery test during the night:

Apolo v4.13 regular (XWMS3 NeatROM Lite v5.8): Battery loss of 0,25% per hour, Awake: 1,1%

That's even better than the best battery life with the same kernel on the previous ROM version.

EDIT:

But it's a little bit worse than for the same kernel on previous ROM version.

I found about 7 minutes SyncLoopWakelock in about 20 hours on battery ... that's unusual as I have disbled all syncing.

Had similar issues after flashing NeatROM v5.6. Last time, I could get rid of this SyncLoopWakelock by enabling and disabling all sync options in Settings > Accounts menu.

Will try it again and report back if it could help this time too.

Here are some screenshots:
[Galaxy S II General] It_ler:
Apolo v4.13 regular on XWMS3 NeatROM v5.8 Aroma:

Second run on AnTuTu: Apolo v4.13 (XWMS3 NeatROM Lite v5.8): 10933

The SyncLoopWakelock is still present ... checking all my sync and app settings again.

Maybe I greenified too much?!
[Galaxy S II General] carlosfl8:
Mate, when you do your test, do your actually do it with the default settings that comes in with the kernel? I wish I could get numbers like yours... Also, what app did you greenified?
[Galaxy S II General] It_ler:
Yes, completely on kernel default settings.

I have disabled some autostarts (links are in the FAQs of post #2), disabled some apps (link is also in FAQs of second post), and I have greenified some apps:

Amazon Appstore, AnTuTu, CHIP Online, F-Droid, Farm Hero Saga, Firefox, Googles, My Tracks, Picasa Tool, QR Droid, Skype, Triangle Away, wetter.info and XDA app.

So mainly every app that I don't want to run in backgroud.

Again excellent battery life in night use.

Slightly worse than on first run, but with better deep sleep ratio.

Better than on first run, but slightly worse than for the same kernel on XWMS2 NeatROM.

SyncLoopWakelock is now gone, but my antivirus app (avast) was active during this test.

So this might be the cause.

In the end, it's a very good battery life and I will stay on this combination for a while ... maybe just a few days :cool::D;)

Here are some screenshots:
[Galaxy S II General] Donnie Sins:
Keep in mind that this is not screen on time with normal usage. If I'm correct, he's using an app to just let the screen on, without any further usage. Please burn me down if I'm wrong:p
[Galaxy S II General] It_ler:
Yes, that's right.

I just want to include screen on /display on time in mixed usage tests, but with easy to reproduce overall usage.

That is nearly impossible with "real life" usage.

The more intensive you use your phone, the higher is the battery consumption. That's for sure.

Hi,

i have a S2

and flash neat rom 5.9 with apolo kerbel 4.13

which governor and scheduler are the best for amazing battery life?
[Galaxy S II General] It_ler:
Depends on your needs/usage/etc.

For me as a very light user, I am very satisfied with the kernel's default settings (CFQ / Ondemand).

You have to check it yourself, as the best combo for one user may not be the best for you.
[Galaxy S II General] xn0live:
i see that u test any combiantion

for example

zzmove with sio

is that good?

i use mosten opera, whats app, any play a little bit

which combination u think is the best?
[Galaxy S II General] It_ler:
No, I don't test any combination ... on some kernels, the number of possible io scheduler and CPU governor combination are much to high.

Usually, I only test the kernel's default settings.

Sometimes, when many users state, that a special combination has better battery life, I test it.

But with my very light usage, I never had significantly better battery life compared to the kernel's default settings.

Might be different for other users (with a more heavy usage).

That's why I said that you have to check it yourself.

Keep in mind that the io scheduler and CPU governor have not only influence on the battery life, but also on the performance/responsiveness of the phone.

So always check both when changing the settings.

[Galaxy S II General] It_ler:
Can't comment on those.

I don't use any battery saver app.

Personally I think that they may help some users, but they can't do magic.

I recommend to analyze your battery stats concerning wakelocks and alarms ... and then try to get rid of all unwanted ones.

I am using BBS app ... others prefer Gsam Battery Monitor and Wakelock Detector app from Play store.
