Apolo v4.11 (Regular):

Excellent battery life in mixed usage.

Apolo v4.11 regular (XWLSZ NeatROM Lite v5.0): Battery loss of 1,12% per hour, Wifi: 10,3%, Awake: 11,2%, Screen: 10,1% => loss*(1-screen): 1,01%

It's again nearly the same like for v4.10 on XWLSW.

The last 30-60 minutes my antivirus (Avast) was running ... so maybe without this, the kernel could have a slightly better battery life.

I will think about giving it another try on a second battery cycle.

Here are some screenshots:

Agree.With my old xperia u,I would hardly lose 1% battery overnight with wifi on.

Battery life was much better in deep sleep with xperia u than on s2

Dont have a screenshot but i do remember running a 2.3 rom (Villain ROM) if im not mistaken having 0% drain over 7-8 hours over night :eek: Flashed the ROM totally not set up not even google account and went to sleep, next morning and it still had 100%:laugh:

That aside NeatROM 5.0 with stock kernel running awesome, battery life as beefy as ever :good:

as promised i found the cause of my battery drain over wifi and i will try to answer your question despite the fact that i am not that good with maths

so it is about 900% less if i am not wrong (plz someone correct me fast if i am :D)

but you can do your math check the screenshots

As i read in several threads and forums sg2 wifi drains battery like hell due to network requests

it was suggested to disable ipv6 from network adapter and from services ip helper, Shell Hardware Detection and Windows Media Player Network Sharing Service ( in windows)

that did the trick at least for me

I am suffering very bad battery times with clean installation of NeatRom 5.0 and not so much usage (7-9 hours) and 38 minuntes screen time, wifi active, synk on two gmail accounts and calendar, etc.

I believe this is still too much battery drain. Can you lads give me some advice? Thanks!

How about installing and using Better Battery Stats (BBS) app to identify the unwanted drainers?

Keep in mind to create an IDLE dump (doing nothing with the phone) for about 4 hours, and post it in BBS thread.
[Galaxy S II General] Squaredot:
Thanks all, I have disabled the location services and just purchased better battery stats (after all the positive reviews and the suggestion).

Will update the thread. I hope my 2000mah battery arrives soon.

One question, are stock roms usually more conservative about battery life than for example NeatRom? My other option is directly installing XWLSZ and a stock rooted kernel.

Thanks and regards.
[Galaxy S II General] bobdoblo:
NeatROM is better than stock, CM, AOSP, AOKP for battery life for me with my useage:thumbup:

What about the Super and Extra-lite version of NeatRom? With the removal of many apps, would that conserve much more battery and experience more performance than the original NeatRom?
[Galaxy S II General] bobdoblo:
To a certain extent, it all depends on which apps you remove but Sale has done a great job with the lite version.

Just use Greenify too and you're good to go;)

Woah, that is amazing. If I cang get about the 85% Battery life that you get from that I will be happy already.

It is shipping from pluto and will arrive still in 20 days. Time enough for my NeatRom to stabilize and see the difference. I think I will see some since this battery already is like 2 years old.

I will keep my S2 until it shatters, no matter how wonderful the Note series is :silly:

Thanks for the testing the different different kernel ..

i want to know that while you testing the battery life what kind or signal are present on your phone (2G or 3G) i mean u use wcdma/GSM mode?

actually i want to know because 3g take much battery than 2g.

hi everyone

i flashed the speedmod kernel and after that my install the cpu z application. i see that the cpu load is always 40%- 50% and the single core i always on 800mhz frequency:( .. and i also i already compare with stock kernel no difference between them only little bit smoother than the stock kernel . i think those who have stock kernel :o has no need to install the speedmod kernel.

the modem and mobile signal matter the battery life.

Hi there. which version of Dorimanx kernel should be downloaded? 8.42 or 9.42?
[Galaxy S II General] Hopper8:
Well if you're on NeatROM as your signature suggests, then 8.42. But please please please begin to read some threads. Especially before downloading anything, read the OP of that thread. It would've told you what you need. But even in general, read the OP of the thread for whatever you download (or intend to download) and it'll save you a lot of headaches. A good way to put it.... Reading is easy, fixing is not.

NeatROM XWMS1: Battery loss of 1,33% per hour, Wifi: 10,4%, Awake: 11,3%, Screen: 10,2% => loss*(1-screen): 1,19%

It's nearly the same as for XWLSW, but I received two messages on WhatsApp and the antivirus app (avast) started its weekly virus scanning during the battery test.

So without these "incidents", the battery life would have been a little bit better I guess.

Maybe I will give it another try ...

Appreciate your hard-work and constant observation

I am trying to understand your comparison with my level of knowledge, so sorry if question itself sound nuts..

which one of these is the best combination according to your hard tests?

a) Apolo v4.10 regular (XWLSW NeatROM Lite v4.8)

b) PhilZ v5.10.0 (XWLSW NeatROM Lite v4.8)

c) Apolo v4.11 regular (XWLSZ NeatROM Lite v5.0)

I have what I have on my signature, I never use mobile data at all, no hardcore chatting, music play, video play on my phone....yet deeply OBSESSED with slimming down/extending batt life to the hilt on my device....there is HAPPINESS doing so :)
[Galaxy S II General] bobdoblo:
Edit, Apolo v10 with LSW 4.8 is best in mixed usage out of those 3.

And actually that is the best combination overall.

Can't find a download link for Apolo v10 but you'll want this for Apolo Configurator

Battery Guide
[Galaxy S II General] insaf_mohd:
Thanks bob, yep I can also not find v4.10 in the OP link

Do I have to really use the Configurator to acheive the best we are talkin' about? Or just install LSW, do a kernelwipe and flash Apolo v10, and I simply have what I need?

I do not theoretically know the rocket science of tweaking kernel apps, just following instructions with possible understanind.
[Galaxy S II General] It_ler:
I recommend to flash latest NeatROM (Lite) version and check battery life with default (PhilZ) kernel first.

Give it at least two full battery cycles to judge.

Then flash another kernel you like, such as Apolo ... I'm always using latest kernel version, as I prefer running on latest versions :D

Also give it at least two battery cycles and then decide, which combination fits best to your needs.

The difference between the different ROM and kernel versions in terms of battery life is relatively small.

So on your phone, with your apps, in your region, etc. the best combination of my phone might have worse battery life on your phone.

My general observation is that Apolo kernel has a little bit better battery life in mixed usage compared to stock/PhilZ kernel.

P.S.:

When I say "stock kernel" I usually mean PhilZ kernel, as it is a rooted stock kernel (with CWM recovery). And I like to have root access on my own device :cool:
[Galaxy S II General] bobdoblo:
No you don't need to change anything, i just gave you link to the configurator app incase you wanted to change anything or try lower voltages.

[Galaxy S II General] insaf_mohd:
Good to hear straight from the horse's mouth @ It_ler

Well you know MS1 and latest patched Philz itself (from NR Lite 5.1.1) give me great endurance in terms of batt life and performance, but your thread is so attractive that makes someone wanna try what you suggest best in the liste due to its cut-throat comparison and judgements.

If you say the batt life difference between newest Philz the Apolo is relatively 'SMALL', I'd stick with the latest stock V I have, end of the day it's all greed for the best :cool: I'll be following this thread.

Hi all!

Well, since I gave the rant about my poor battery life I wanted to let you know that I bought the extended battery and wow, this is a different phone! I installed NeatRom 5.1.1 with Philz and standard settings, just ticking power saving options enabled, and now I get over 20h of my normal everyday phone usage ratio, which is perfect for the day. Well, it could be better, but this let's me focus on other aspects than struggling to make mi phone survive.

Hi It_ler,

What about XWMS1 with Apolo 4.11 ext v0.

Does the battery life also depend on what mods I have installed Or how many apps are installed on the phone.

Does greenifying an app help save much battery or just little
[Galaxy S II General] It_ler:
Extreme versions of Apolo kernel are not stable on my phone. Usually, I am running light or regular versions.

So you have to check if the extreme version are stable on your phone ... then you can use it.

With my very light usage, the undervolting will have only small difference for battery life - maybe the difference is bigger with a more heavy usage.

The battery life is influenced by many things ... the installed mods are not that important IMO, but the running/active apps have a significant impact to your battery life.

Greenify an app will set it to a kind of "hibernate mode" when it is not running in the foreground. So it mainly prevents it from running in the background.

If you greenify an app that runs "massively" in the background (even if you don't need/want it), then it can save a lot of battery life.
[Galaxy S II General] It_ler:
Apolo v4.11 regular:

Excellent battery life in mixed usage.

Apolo v4.11 regular (XWMS1 NeatROM Lite v5.1): Battery loss of 1,14% per hour, Wifi: 11,2%, Awake: 12,0%, Screen: 11,1% => loss*(1-screen): 1,01%

Unfortunately, I had to abort the battery test after 18,5 hours (and could not let it run for about 20 hours as normal). So the battery loss in % per hours is higher than it would have been after additional 1,5 hours of idle time.

It might have been slightly better than for v4.11 on XWLSZ.
