I got best results with below ROMs, however, after setting it up properly..

1. Beanstalk

2. AOSB

3. Cyanfox
[Galaxy S II General] Kasun72:
Thanks im currently using PAC rom kitkat.but i get only about 2 hours of screen time .how much you get in beanstalk rom?
[Galaxy S II General] NeffeZ:
I'm currently using Ehndroix V.

It's based on CM11 (4.4.2) and I'm really happy with it.

The battery-life is better than ever (at least for me) and the UI is very fluid.
[Galaxy S II General] banjara:
With normal usage, on 3g, no Wi-Fi, approx 2 hrs SOT, I could get on

1. Beanstalk - 42 hrs

2. AOSB - 40 hrs approx

3. Cyanfox - 37 hrs approx.
[Galaxy S II General] pipyakas:
I really tried to do the same thing, and wat i got was a 2h screen on time (playing games to be precise, asphalt 8 and gta sa most of the time) and a 3h charging time. And i also have a annoying battery drop issue, it drop to 10% or less after a reboot. It would be much easier to control the battery usage if i can fix that problem.

Reverted back to stock after gave cm10.1 a really big shot. Battery life is now the only thing between me and hours of endless fun with the phone

edit i was really shocked to hear that someone actually pay for a root. Android was all about open and free and honestly, i've never ever paid for anything related to software so far
[Galaxy S II General] torstenconrad:
For battery life, stick to stock JB.

From own experience, fully stock JB lasts longer than the custom stock ROMs out there. More features = more drain.

Flash stock deodexed and remove the apps you dont want. Right now, I have 29% left, been 1d 23h 31m unplugged, and screen on time shows 3h 19 min. Stock kernel too - and this is only the 1st cycle charge!

Please post the Apolo kernel download link.....
[Galaxy S II General] Zile995:
Where did you find deodexed rom?

I want to flash them in custom recovery.

Yes stock is great. I got 3h 40m 1% left.

on rr5+apolo7 = 3h 10min

Neatrom 6.3 + apolo v14 = 4h+

Stick with JB if you want better SOT.

I hear SlimKat has amazing battery life.

Personally, I use PACman and the battery is pretty good.

Also try apps like Greenify and SetCPU, they work wonders=p

Could you share that ROM? And which kernel do you use?

Many thanks!!! :fingers-crossed:

Cool

Hi, where did you download JB compatible Apolo Kernel from???

Thank
[Galaxy S II General] souler456:
Here you go mate: Google Drive

Choose Branch 4.x and for starters, try regular version first. Then go to extreme versions (from 0) if you want more underclocking on the kernel (may cause instabilities on some S2). :good:

:D :) ;) :good:
[Galaxy S II General] thedarkdevil420:
Cheers

COOL, Thanks, except, (probably a newbie question) neat rom would be 4.1.2 so, are all these compatible with that 4.1.2. Which one should I get? Probably "Apolo_4.14_Regular-CWM.zip" from 4.14 (rom sammy)?

thanks a lot for that.....

I don't really use CM10.1/10.2, so better try it yourself. Why not use KitKat ROMs? It's pretty stable for me, specifically the SlimSaber... :good:

[Galaxy S II General] Redsandro:
Is there really much difference?

I liked BAMrom and ParanoidAndroid. I also tried a lot of others and usually I personally found them to be crappy or laggy or microscopic. But the battery life usually seems similar-ish.

So now that the only two I like no longer support SGS2, I'm wondering if there's something at least as good out there. Some say SlimSaber is battery friendly. But: Really? Or is it another placebo, as one would think, looking at the wide variety of opinions?

(Tried NeatRom, didn't like.)
[Galaxy S II General] russy23:
ive only tried 2 kitkat roms, first being the last buld of cyanfox, cant fault it, then tried lollipop but atm buggy but getting there, so come back to paranoid android 4.4.4 the last stable release, i dont think its as polished as cyanfox and get unfortunately app has closed sometimes..might try slimsaber but im not sure which release is the most stable
[Galaxy S II General] foreign body:
Neat ROM extra lite with Apollo seems to be the best.

Slimsaber 4.4.4 by Fusionjack and dorimanx 10.44 v005 by computoncio. Simply awesome.
[Galaxy S II General] kai1313:
can you show your stweak ?

im using this combination also, slimsaber 4.4.4 fusionjack and dorimanx kernel

and if i may ask, which better(stable) build dorimanx for i9100 between computoncio or cybernetus(i cant find the 10.44 v005 from cybernetus site)
[Galaxy S II General] Saber:
v005 is only available from computoncio's website (hence it was built by him). Link: http://dorimanx.casoncia.org/index.php?dir=V10-MALI-V3/ There are profiles on the dorimanx stweaks profile thread where you can find profiles from myself and others too. Computoncio's builds are more stable than cybernetus, but cybernetus has been using computoncios git anyway for his latest builds.
[Galaxy S II General] kai1313:
so is it the same if i use the v005 that i get from computoncio site?

thanks for replying
[Galaxy S II General] Saber:
Yep.

When i had the s2 i was using Jellysnapp.. I think it.s ok..but s2 have big problem with battery..it.s too low in capacity!!

Now i have N4 witch is really great and i recommend it to you all..32 h battery? Cmon..
[Galaxy S II General] ferenczoltan:
The journey continues...

I went flash-crazy and ended up with a combo of CM10.1 and a Siyah kernel (I thought...) which gave me 22 hours before the low-battery warning on a 2600mAh battery, about 35% screen-time. (6-8 hours on stock[!])

Thinking I could do even better I kept flashing, lost the combo and didn't have a backup - DOH!! ALWAYS BACKUP GOOD COMBOS AND BACK THEM UP TO PC...

For the life of me I couldn't flash another kernel to 10.1 and only managed at best 12 hours before the low-battery warning (roughly 35% screen) with the cpu limited to 800mHz (no noticable [extra] lag - I don't game) So seeing as a couple of posters mentioned the above combo I thought I'd give it a go, but first without the Apolo kernel. Given I don't play games I installed CPU Tuner, limited the cpu to 1000mHz, and yesterday I got 9hrs/50% battery left (screen 35%) and today 11hrs/45% battery left (screen 37%).

Wonder what the Apolo kernel will do?

Can I be bothered...?

[Galaxy S II General] AVFA:
İ tried many ROMs and kernels. İf you want best ballancce for battery and game, you should use NeatRom 6.4 lite + Apolo ext v1 for now. You need to remove some unneccassary system apps with titanium backup, for example exchange services, e-mail, google tts, samsung apps..... And i really recommed to use Greenify app for sleep any app that you not use very often. I play clash of clans for 15 mins with 3g network but charge drops only %2. Really good playtime. Btw, no freez no lags, no overheat with this combination.

Hi.

As of today, which is the most stable and battery friendly rom? What are other suggestions? Would you recommend lollipop based roms? In that case, which one?

I don't really care about games as the previous user was asking, that's why I'm asking again.

Thank you for your time
[Galaxy S II General] lohtse:
lol which one(am on android 4.1.2) theres several
[Galaxy S II General] joebelachi:
I'll watch and see from here onwards..

Hey all.

So like most S2 owners that have come across this post, I'm hoping that I am at the end of the journey (at least for now) to find a ROM that gives me good battery life on my S2 GT-I9100.

PROPS to the original poster for starting this thread. Read it several times, and here's my journey:

Problems began with the last JDI update I9100WBMS3, and the one just prior to that. Always used stock ROM. In addition to wanting a fresh interface, the battery woes were killing me primarily, and performance started to suck a bit after installing a few games.

Here is my experience with some of the better known ROMS, in order of what I started with first - Always did full wipe, install ROM, SU where necessary and GApps:

1st - HAZY. (Lollipop)

The Good: Beautiful and clean. Stable. No app crashes. Nice Lolipop experience and flavor.

The Bad: Battery drains from 100% - 0% in like 6 hrs (1.5 hrs talk time, no games, no browsing)

2nd - Euphoria. (Lollipop)

Same as Hazy, few more customization. Battery life sux

3rd - BeanStalk (Lollipop)

Almost same as experience Hazy and Eupho. Battery life sux

4th - NeatROM 6.4 + NeatROM Kernel

Didn't get a good chance to see Battery life, but after full charge, BUT I could see that the battery life was going to be better. Not wanting to be stuck with 4.1.2, and with my ROM flashing addiction on full overdrive, and I couldn't resist doing another ROM a few hrs later. Which leads me to my current ROM in use.

5th and CURRENT:

CM 10.1.3 stable + Dorimanx-V9.43 Kernel.

The 4.2.2 flavor is not bad, definitely better than the old stock one in NeatROM. Battery life appears to be good based on posts i've seen here, and my past experience when I just got the phone. :o See images attached for battery use.
[Galaxy S II General] lohtse:
could you provide a link to thread for the rom you mentioned?

Modem KH3 And Custom Rom CM 12 03/06 build by Lysercig Agid with kernel of his rom battery is no long last.....Recommented please kernel!
[Galaxy S II General] dark1ro:
Hi All,

From my point of view the optimal settings for battery life are the following.

1. CyanogenMod 10.1.3 Stable. (clean install)

2. Added DorimanX Kernel 9.43.

3. Added XXKH3 Modem - You can try different modem if this one doesn't fit you, but this is the one that really helped me when it came to heating up the device. Also 3G speeds are great !

4. Used Greenefy to stop apps from autostart.

Hope it helps.
[Galaxy S II General] RuffBuster:
After trying almost every rom available I also made the move to jelly bean 422 but slim bean variation. Tried most of the 422 builds, cm10.1.3 is a good build, ran it for about a week.
[Galaxy S II General] BettlePimp:
Anything better came out in terms of battery life or is cm 10.1.3 still the best? Also what about the kernel?
[Galaxy S II General] darkpollo:
Hi, Why 9.43 and not 9.44 which seems to be updated after 9.43?

Thanks!
[Galaxy S II General] darkpollo:
Hi,

I am trying to install cyanogenmod with the kernel but when I install the kernel before the rom, the rom replaces he kernel and if I do it the other way, the Phone does not load.

Which combo did you use? Thanks
[Galaxy S II General] Saber:
You probably installed the wrong version. CM11 requires dorimanx 10.44 to be installed. CM10.2 and CM10.1.3 should be 9.44 and etc. The official version of dorimanx is not the one you don't want unless you're going for stock.
[Galaxy S II General] darkpollo:
Yeah, thanks, that was the problem.

After all, I have tried with CM10.1.3 and the 9.44 and the battery was the worst. I was affected by the Google Services Drain all the time.

Now I am on the Slim ROM which I think is not the best for screen ON time but it is great when the screen is OFF so I think I will survive with it.

I cannot understand how people can say CM10.1.3 works fine. It is not my experience so far.

Cheers!

Is any one know a fix for android LP mem leak,

I tried most of LB roms for S2 all are the same

I never have the battry life i was having with KK

Thnks
[Galaxy S II General] sharp87:
Afaik 5.1.1 has memory leak fix... Every LP rom for s2 still has many Works to become more stable and battery friendly..
[Galaxy S II General] ninestarkoko:
yea LP roms are still bug-full but especially some (like Mokee) are updating daily and fast. I think that , at this stage, using a KK rom (at least updated in November or December 2014) with Gustavo's kernel can give the right stability and bettery life.

Dorimanx kernel, since Dorimanx departure (i remember when he tested his builds a lot before releasing) , seems not very reliable.

Best ROM for i9100

Hi guys. Since I broke my S4 and I'm still waiting for my replacement LCD, I decided to get back to my old, trusty S2. Wanting extreme ratio of performance and battery, I decided to try out this , Andorid 4.4.4 combo (note: I've tried CM11 and CM12.1 but these roms are waaaay tooooo buggy, slow and do 1 MPG in terms of battery life)

ROM: SlimSaber - i9100 Latest 4.4.4: 20150406 (link: http://xdaforums.com/galaxy-s2/development-derivatives/rom-slimsaber-i9100-t2350201)

Kernel: DorimanX 10.45 v022 (BETA) (link: http://xdaforums.com/galaxy-s2/development-derivatives/kernel-dorimanx-jb-4-4-4-t3123487)

Gapps: Open Gapps (arm, 4.4, pico version) (link: http://opengapps.org/)

I've just flashed everything and the speed... is... amazing. Of course I have not yet installed any apps, tried out real-life battery stats, but when I will, I'll post my findings here.
[Galaxy S II General] PrimozI:
Do you already have any stats to share, perhaps?
[Galaxy S II General] blazboi:
Which ROM has the best battery life out of:

CM 10.1.3 stable + Dorimanx-V9.43 Kernel

NeatROM 6.4 (4.12)

NeatROM 8 (AOSP 4.4.4)

SlimSaber 4.4.4 + Dorimanx-V10.44v005

Stock 4.1.2
[Galaxy S II General] :
IMO you can't beat stock for battery or stability. The other roms you mention(depending on the version)are all very good for both stability and battery, but you can't ask how good battery life is with a custom kernel, it depends on the kernel settings you have. You can get very good battery life with any of these roms with some tweaking in stweaks
[Galaxy S II General] blazboi:
stock or neatROM 6.4?
[Galaxy S II General] vyrussu:
in my opinion, best rom in terms of battery is SlimSaber 4.4.4 + apolo kernel ;)
[Galaxy S II General] blazboi:
what settings do you have to maximise battery life?
[Galaxy S II General] qWantUS:
Hi there. And how did it went? I am looking for a very stable rom (for my mum) which would be stable enough to use for month without reboot... battery life is also very important... I am even considering to go full stock. Just to be on safe side... features not very important. As long as viber and skype running fine that is pretty much all is required from this old timer [emoji5]
[Galaxy S II General] vyrussu:
i leave it stock.
[Galaxy S II General] blazboi:
which apolo kernel do you use?

is apolo or dorimanx better for battery?
[Galaxy S II General] Saber:
For kitkat, use 7.3. For 4.1.2 Jelly bean, use 4.15b.

IMO, Dorimanx is a little lighter for me on battery life. But experience will vary.
[Galaxy S II General] Galaxy X7:
Hi there - sorry for a very long responce. Go full stock, seriously as I've encountered coutless lags, stuff not working properly ect. I don't have time for this anymore :D
[Galaxy S II General] blazboi:
Is there a difference in stability and battery life between neatROM 6.4 and stock?
[Galaxy S II General] Saber:
Pesonally, I think that neatrom is more stable since most buggy samsung bloatware can be removed. But in terms of overall, stock should be more stable. Battery life is what you would expect for stock 4.1.2, neatrom I think is a little more battery friendlier once again since there is less bloatware hogging up CPU and RAM.
[Galaxy S II General] hwasdin:
As for today - which Kernel + Rom is the best for the longest battery life? Still Stock (4.1.2) oraz maybe SlimSaber 4.4.4? Cm11? Or maybe something else?

Thank You for ane answer :)
[Galaxy S II General] Saber:
Stock 4.1.2 usually has better battery life than any custom rom (better than kitkat and lollipop).

regards, gsstudios
[Galaxy S II General] mspector:
I second that. I own an I9100 and I have 4 batteries (two are Samsung originals), none of them are lasting more than 8 hours now. And it's HOT almost all the time. Been using several roms (latest one was LiquidSmooth) and none seems to be a real good deal.

Another issue I'm having with custom ROMS is installing GAPPS. Basically all of them gives me "insufficient system space" error, even tho I've already re-partitioned my internal SDCARD.

So, thoughts? Thanks a lot!
[Galaxy S II General] hwasdin:
I had the same problem. For me the solution was to increase memory size via Odin (type "Increase Size Memory in Galaxy S2" - in Google - and U will find what u need, step by step).

Thank You for reply. So still stock is the best solution. But shame it stops on Android 4.1.2 :( Another question: There is no "newer" version of JB? (with 4.4.x) ? And if not compare to all custom ROMs with Android 4.4.x which one has the best battery life? (SlimKat, NeatRom,etc. + Which Kernel?) - as for today. Thanks for any answer. :)
[Galaxy S II General] Ghost-of-the-Sun:
I think I'm going ti buy a new phone because of Galaxy S2 battery life.

Lollipop still has very good performance on our phone, but battery just can't last.
[Galaxy S II General] hwasdin:
My "summary" of 2 ROMs - battery life:

1 - SlimKat 4.4.2 - the longest time without charging: 2 days 13 hours - with normal use: texting/calling/using Internet etc but:

- Black wallpaper

- Brightess - 0 (no Auto)

- Greenify

- 2G

- WiFi on - only if necessary

- NO PLANE MODE!

2 - NeatRom x6.4 with AOSP ligth - THE BEST!!! - 3 days 2 hours, and still 28% of battery left - with normal use: texting/calling/using Internet etc but:

- Black Wallpaper

- Brightness - 0 (no AUto)

- Greenify

- 2G

- WiFi on - only if necessary

- NO PLANE MODE!

I've been looking for the best ROM, which will give me the longest battery life and finally i found it - no stock, but NeatROM! Cyanogenmod, SlimSaber, OmniROM, CyanFox .... - i've tried every ROMm but Neat on Android 4.1.2 - is my choice and i recommend it for those who want to have a long... the longest battery life :)

/ ;):)
[Galaxy S II General] mspector:
Well, I myself am good regarding ROMs now.

Been using Validus ROM, Lollipop 5.1.1 based, for the last month, and I'm really happy with it.

Camera is not crashing anymore.

Phone not getting hot anymore.

Battery charging each 2 days, and even after 48hs I still have about 20% battery left.

Only issue so far is GPS - it's draining battery really fast (like, 4 hours straight with GPS and screen on drains battery almost completely). But I only use it this way in the car, so no big issue there - I just plug my car's USB cable into the phone and it's all good.
[Galaxy S II General] FDiHD:
do you have a new battery ? or the original one..
