Hi all,
Many of you have upgraded your firmware thru leaked versions posted elsewhere on this forum. My question is to all those who have used the leaked versions. What are the points of difference between the performance of these three versions : KF3, KG1 & KG2. If I understand correctly, only KG1 has Android 2.3.4 out of these three versions. So if you can share your experience about whether there is a change in Battery life, smoothness of operation, other visual changes etc.
We, in India, are still on KF3 officially and still waiting for the KG2 upgrade via Kies. But I'm using KF3 currently and Battery life has improved considerably over KE8 in the current version. Is it worth upgrading to KG2 via the leaked firmware or should I wait for the official update from Kies?
I'm on the leaked KG2 2.3.4 with a custom ROM.
I must say, battery life is amazing. I can go through a day of heavy use leaving home at 7am and getting home at 7pm with 40% or higher battery life remaining.
Mind you, this is heavy use from watching netflix (movies), browsing the web, texting, phone calls, and playing games all while the 3G is running in the background with gps location, email syncing ans google sync.
So far, I'm loving KG2 2.3.4.
I was running KG1 2.3.4 for about a week before flashing KG2.

KG2 modem does have a stronger WiFi signal .
jje
I havent had any real battery problems since I swapped to a custom rom and nuked all the bloatware.
2.3.4 has its advantages like video in gtalk and the androidOS bug is all but gone (for me anyhow)
As far as wifi, I never had any problems with it, maybe it didnt show that many bars, but it didnt seem to have any problems even on 1 wifi bar
Looks like KG2 is an improvement over the previous firmware. I am tempted to switch to KG2 immediately going by your encouraging feedback. Will wait for a few more days for the official Kies release to come.....if it doesn't, then I'm also gonna flash the KG2

It is 2.3.4.
Thank you, Octavius69, for confirming.
KG3 has the best battery life ever. Today I watched movies, played games, I had screen on time of 3.5 hours, and battery was at 55%. That means if I kept on, I'd get around 7 hours of screen time. A big improvement over KG2, even though the Android OS bug is still there.
Is anyone else having a problem with their wifi being connected and not working?
Ever since i flashed KG2 with the one Darkyy released ( Thanks by the Darkyy) everything has work perfectly and battery life is great. The only thing is the wifi and it seems to happen after it's been connected for awhile and when i wake the phone to browse say the market, it doesn't have a signal even tho 2 bars are showing, so i reconnect and it works again. It only happens now and then and i think there could be an issue with the mobile network as a couple have calls have gone to voicemail even tho i'm sure i had a signal.

Did you flashed stock kernel? It's a known prob that stock kernel could break wifi.
Just got my GS2 and having HORRIBLE battery life. It's locked with 2.3.3 KG2, so I'm wondering if it's a defect or if it's the build, in which case I'll get 2.3.4.
Other than the battery issues, I love the phone, but I already miss my Nexus One just a little...
I've used ninphetamine 2.1.3+ and it used to drain my battery a fair bit. After having seen another user who said he was experiencing better battery life with ninphetamine 2.0.5. I flashed the older version and it turns out to be indeed better.
My idle drain rate is now 15-17mA using Battery Monitor widget.
So when put in picture. Drain rate is about 2% per hour with minimal usage. (Note 3g data was on)
Anyone else have a better kernel?
EDIT 1:
I've tried using SiyahKernel (KI3) and it seems that according to Battery Monitor widget the idle battery drain is 14-15ma. Seems to be much better. However, occasionally the touchscreen freezes and only the touch button works. But then again it could have been because I was using the KI3 kernel on a KH3 rom. Would report back after I finally get off my lazy ass and flash a KI3 rom
EDIT 2:
Got off my lazy ass finally. Flashed LeoMar 2.7.1 rom with SiyahKernel 1.7.8. Will report back after a while. Though I must say that for some reasons after the boot animation the phone turns black for quite a long time (1-4 Seconds) before the lockscreen appears. This did not happened with the default LeoMar 2.7.1 kernel. Will report back in 24 Hours.

Thanks sherlock. I posted my findings and was asking if anyone else had better. If it the time of the month of you. Stay off this forum.
Personally I find it very difficult to make meaningful comparisons, especially at idle.
Battery Monitor Widget gives estimates and not actual current drain. See this thread for some discussion: http://forum.xda-developers.com/showthread.php?t=1056486 but basically it's either not in Samsung's battery driver or the app is not reading the information. So you are comparing estimates and the margin for error might be pretty large.
When you flash new kernels you also need to recalibrate the battery. That also affects your battery drain estimates. (I've had Battery Monitor Widget tell me my battery is going up when its unplugged, so go figure.)
Battery life at idle is affected by so many factors. Maybe your signal strength is better one day than another. Or you got more emails or did more syncing. Or one app just happen to glitch and have a very long wakelock. If you get battery drain, you should be checking your partial wakelocks with BetterBatteryStats. Did you get more partial wakelocks when you were running Nin 2.1.3? Is it the kernel's fault or did you just have a misbehaving app?
I like experimenting with different kernels too, so my point is don't expect miracles when somebody says Kernel X gives amazing battery life compared to Kernel Y. Personally I think they are all about the same at idle, and the big differences are in your settings and your usage. If you wipe your phone, don't add any Google or Exchange accounts, and don't sync or download anything, your battery will last 3 or 4 days on idle no matter what kernel you use.
Stock rooted KI3 (cf-root) is the best for battery life for me, i also have constat 3800+ quadrant score (with top of 4109 as my screenshot in leomar 2.7 rom thread).
Also i have the phone a lot, but really a lot less hot while gaming or stressing it.
KI3 stock kernel and SiyahKernel are at the moment the best in battery life. Anything else is running on older sources and drain more.
The best for me is SpeedMod! Smooth and long life battery. There is something you can't do (bootanimation oc uv bln) but simply great!
Inviato dal mio GT-I9100 usando Tapatalk
best results for me: stock kernel reflashed after rooting, for that stock rom.
Bar none the way to go.
Stock Rooted KI3 does look good, am yet to test it though
Hmm. So seems like you guys are experiencing deliciously good battery life with KI3 kernel. I shall try it and report back with some numbers.
try siyah kernel. one of the fastest growing kernels IMO
For me is Ninphetamine 2.1.3 and now i'm trying SiyahKernel 1.7.7
My question is.. between stock ki3 and SiyahKernel 1.7.7 the difference is really small (barely notice it) or big?
I tend to not flash to much kernels since the very small chance to corrupt the efs folder (even if ofc i have my backup), so if it's only small improvement, i stay on the stock ki3, if it improves a lot, i prolly try it
I've been using the siyah kernel v1.7.7 and I've been experiencing a great battery life. I didn't use the stock kernel for long to make a comparison but I sugest you give siyah at least a try, since you can always go back to stock if you don't like ir.

batistaRom and ninp 2.0.5 great battery life for me...if you like i can post screenshots if anyone is using setcpu, depending on your kernel try and research in the kernel thread regarding frequencies that other users suggest and adjust yours accordingly...thats what i have done for mine and i could not be any more happier
Alright. I've finally got off my lazy ass and flashed a 2.3.5 rom (LeoMar if you must know) and am currently using siyah 1.7.8. Will report back within 24 hours after I've put the device through a day's use.

Pix or it didn't happen
Hi, I posted earlier saying that siyah 1.7.7 gave me good battery life. I tried now the cf root v4.2 KI3 and I had better results. Well, I'm someone that don't play many games, but I surf a lot and download a lot of stuff on wifi. I don't care much for overclocking so I think I'm going to stay wth KI3 cf root. For me they're both great for battery life, and maybe the other ones I have not tried are great also (speedmod, ragemod, ninphetamine...)
I think what happens with kernels, and this happens also with custom ROMs (and everything really, brands, etc..) is there is a lot of fanaticism. People like to choose one ROM and kernel and stick to them. They start to defend the kernels they use convincing themselves they're the best no matter what. That is in my opinion the reason because this kind of discussion turns meaningless. Well not that meaningless, at least it gives an idea of the kernels people are using, at least we know speedmod, ragemod, siyah, nimph, are all great kernels.
I'm not criticizing anyone, in fact, I'm just another example of the people I described.
Hi everybody !
Let's make a poll about the huge question of the moment :
Are you really experiencing better battery life in Gingerbread 2.3.5 over 2.3.4
Please vote above !
And please try to report only after doing a properly battery calibration and at least 2 intensive days (or normal) using !
Yes, I clearly see a difference !
With the stock rooted KI3 (CF-Root), that's important because with any other kernel i have worse battery life than kh3
I always have a intensive use of the phone, and in last 2 days after i flashed the KI3 (keeping the stock kernel) i play double time, same phone calls time, same number of sms sent and i finish my day with still a bit of battery left.
On KH3 i had to plug my phone charging during the daytime.
Totally different opinion comparing to th guy above me. KI3 for me is not better then KH3 which I used before
Sent from my GT-I9100 using XDA App
Definitely better than any before.
Sent from my GT-I9100 using XDA App
Night and day difference for me. Instead of having only 25%-30% left at the end of the day I have 40% and above now... that's after about 22 hours off the charger.

I think exactly the same actually, but I prefer to not vote on my own poll right now because I just migrated on 2.3.5 since yesterday only, but at first impression I was more pleased on KH3 (2.3.4), or maybe it's same for me. Waiting to test few days more to really put any judgement.
Still waiting for a nice AOSP theme for it before i switch i think

Hi Intratech.
Would be very interesting if you could share how your phone is configured (3G, Background Data, Auto Sync etc), which kernel you use, tweakings and so on.
Thanks.

Exactly. With KH3 (which was significantly worse than KF2), I would barely have any juice at the end of the day (ran out a few times in fact). KI3, I easily still have 40%+... there is a HUGE difference.
Thank you Samsung!

I'm using the Frankenstein build. My emails are set to sync every hour, Gmail gets pushed to the device. SNS stuff is set to sync every 3 hours as I manually check stuff inbetween and it gets updated anyway. Data connection always on, background data is allowed. I'm using the stock kernel. The scheduler is set to on demand. No task killer is used.
I haven't actually had the time to do any tweaks to his firmware to make it my own setup as yet so it's pretty much vanilla apart from the stuff that's been frozen: Games and Music hubs, AccuWeather ( I use Beautiful Widgets instead), AP Mobile, Buddies now, days, Digital Clock, Dual clock, WiFi sharing and WiFi sharing manager and Yahoo finance.

Well, apart from the kernel (I'm using Ninphetamine 2.0.5), the rest is almost the same, with the exception of Bluetooth and WiFi Sharing (all freezed), and several Samsung addons uninstalled (music/reader hub, tasks, diary, buddies, live wallpapers etc).
Unfortunately I can't get more than 16 hours, which is insufficient to me. Yesterday I flashed only the original modem.bin of my carrier. Let's see if this provides some different scenario.
Thanks one more time.
Regards.
Using Better Battery Stats, I find my Awake time is always the same as my wifi on time.. and much much higher than my screen on time.. I'm baffled right now.. apart from that.. KI3 does seem great to me.. but my battery is in pain.
2.3.5 is the best so far for me buddy. switched to Foxhoud by BatistaRom and so far 3 hours and only 5% battery drain....hope that answers your question

That is the same thing just a no-wipe version and maybe a little modify. I always used firmwares from samfirmware and since the last firmware i think it was ki2 i had a good battery life. 4d8h max i had and with some use. This one now i have 2d8h and 32% of battery left. So i can't be if i didn't use Intratech's Frankenstein package
My battery life has also improved with 2.3.5. I'm running Leomar75's revolution ROM v2.7.1 with siyah kernel.

Ninphetamine is a fantastic kernel, but that's why you have drain.
Old kernels are not optimized for the 2.3.5
Try the stock rooted (CF-root) or the siya one.
You can always go back to ninphetamine when a 2.3.5 optimized version is released.
On the 2.3.5 the stock one is faster than the ninphetamine (3800-4100 quadrant score all the time) and battery last really a lot longer.
Also the phone under stress is a lot less hot.
Just my 5 cents i think its worth a try for you so you can check if it is better.
Again, im sorry for my poor english.

i actually beg to differ. im using batista rom based on 2.3.5 and using Ninphetamine 2.0.5 and so far 6h and 35 m and only 7% battery drain. and thats with wifi on all the time and browsing here and there. so far so good for me i say..but its always down to personal preference what kernel suits your needs i say..Different handsets kernels work differently

Ye, i think at the end the best choice is to try and see wich one best fits your personal desire. Also a kernel can act different on a S2 than another S2.
I always suggest based on my experience, but ofc can be totally different for someone else.

I will be traveling soon. I have the JellyBean leak by izap on my phone right now... The battery life is somewhat ok, but I have network issues with it sometimes. People can't get to me even when my phone shows full signal strength. Therefore, I would like to know if there is a Modem/Ril/Rom combination that features stability and is most suitable for making and receiving calls internationally. It would also be good if the combination isn't a battery sucker while searching for network while not in range.(Because this seems to be an issue with many people :-/ )
While traveling these are my top requirements from the GS2:
Stability- no SoD or incompatibility with networks abroad.
Battery life- no battery drain while it isn't being used
GPS- quick locks in remote areas (I already seem to have a solution for this; but haven't tested it yet)
Camera- no pink spot or noise (Could you also recommend a good camera firmware for Fujitsu M5MOLS that fixes FPS issues and pink spot? -I've tried solution in every Camera issue thread I could find on the forum, but I still get pink spot)
Thanks! I'm looking forward to your replies! :fingers-crossed:
Just in case this question isn't in compliance with the forum rules, then I'll be sorry and the Mods can move it/delete it.
If it were me Id just go back to Samsungs proper stock rom/modem.Then when I come back,Id change it back to what I liked.

Thanks for the answer... But I wanted to know of a combination of any rom(stock, custom, etc) and Modem/RIL that provides good compatibilty with overseas networks and isn't infamous for draining the battery... And stable

To be honest your expectations are too high.Your wanting what everyone on here wants,and it doesnt exist.This is why were all tinkering with roms.
In some of requirements,while one thing improves,another will diminish i.e battery life.
I currently use rooted GB stock,stripped down with all the crap removed.I used to use nelp3 modem(gave best signal),but according to callers,speech was choppy.
I'm on NeatRom Lite 4.0 (JB leak), and see in better battery stats that "No or unknown signal" is 99.3%, and I have been in areas with good reception all day, so something is not right with the LS6 modem here in Norway. And I'm not sure if there is any other modem/ril for JB leak?
As for stability and battery time, CM9 stable worked great for me, so maybe have a look at that? With litle use, batterydrain where less than 10% pr 24hour on stock battery...

You can use other modems for Leaked jb but not other rils.
Leave ther ril alone and change the modem. Read through the thread for information how to change modems.
Will it not make phone reception worse if ril is not matched to modem?

I see in here that I should be using a XW modem, and not the XX in the leaked jb rom, so I better try another modem and see how it works out.
@jj_95nano You should probably have a look at the modems for the region you are travelling (2 first letters), but as that thread has not been updated since summer, I don't know if theire recommended modems are still valid...
You could also maybe check the signal strength of your provider on where your going.
I went on holiday recently where the tmobile reception was crap,and vodafone was a lot better.
*gets into a dilemma*
Just flashed the latest stock ICS 4.0.4 for my region... There are many bugs and FCs... I wanna flash GB, but the GB for my region is infamous for its battery drain. I guess I'll keep CWM Backups of different ROMs and try them out when I'm on the go. :-/
Depends where your going ^^
If I was taking my S2 over seas, I'd get a sim card for that region (could prob get one prior to travel), leave a redirect to no. on my voicemail. Then I would get a cwm flashable modem for the region & install it on the plane to destination. Rom wise, MIUI gb/ics - would be your best bet... everything works out of the box. Stay away from JB, unless you have a laptop handy, then it wouldn't really matter

Okay.. So I'm downloading MIUI and I have some modems of the places I'm gonna go to. The only problem is everytime I flash a modem there will be a Modem+RIL mismatch... But actually to solve that I can flash only one modem for the country I'll be in the longest. Let's see how it goes!

Yep I'm on a plan with international roaming... I finally got MIUI ICS and NeatROM Lite dual booted. The modems on the ROMs are matching with RIL and don't seem to be draining battery, so I think I'll stick to these.
Hello,
I'm running 2.3.6 now and I wonder if I switch to 2.3.4 will I have less battery drain? Are there any functional lacks on 2.3.4 comparing to 2.3.6? However, I use GO Launcher on rooted phone.

Well next time please do post questiona in the general sub forum Anyway I think it is better to just update to 4.1.2 since you are rooted anyway. I get better battery life and signal on 4.1.2 compared to 2.3. My choice of a rooted stocked based rom would be NeatROM Lite by Sale :good:
I agree. Generally, upgrading rather than downgrading will increase performance so I would just go wit a higher version. Also, if you feel you have an unnatural battery drain, there are other options except switching versions to handle that. Maybe it is one of your apps that causes the battery drain. Other possibilites are sync cycles or kernel. If you switch to another kernel that might help your problems better than switching ROMs (although switching ROMs is always recommended, just for the fun of it )
gulypi which
I don't know if I am doing something wrong, but I just flashed NeatRom 5.0 and the battery life is terrible.
From my point of view, 2.3.4 stock with speedmod kernel was the best with my s2. I had battery life for 2 days. With latest roms I have battery life for max. 24h. I always did a clean install with factory reset. Don´t know why the battery life is so bad with my phone.
But now I ll give it another try. I will format the whole phone and try sentinel rom again which i liked most
NeatRom 5.0 killed my battery also. Trying 4.9 for now as I jumped from 4.6. If it's buggy I will switch back to 4.6

Media scanner fix for battery problem on neat ROM should fix this. Also Apollo kernel is great mix with any stick Sammy ROM.
I don't know why flash modded kernels (at least if you are about to have better battery life, not other mods)? I have plain stock GB 2.3.6 XWKL1 (DDKL1) and just use Go Power Master, Set Cpu and calibrated battery.
At first when I went back from ICS to GB battery lasted for 14hrs. I charged battery fully on and battery "learned" new system and went up to 23hrs. Then I calibrated battery: fully discharge till phone went off, again started, playing till off again and again till it won't on. Then without turning it on I charged battery fully, unplugged charger, waited till battery went to 99% and plug in charger again till 100%, and again. I was using WiFi over half time of usage, flight mode at nights, play wit phone settings, installing apps, browse internet a little, use as phone as usual, listen a music a little, browse photos, etc, and battery lasted for 39hrs on stock battery which previous owner using for last two years and he didn't care about healthy battery usage. I got Samsung Extension Pack with 2000mAh Battery and flat back panel but it waits for new S2 I bought yesterday. I will put new battery after ROM flash and get all restored to state I have now, then I calibrate that bigger battery for new phone.
But anyway, question was if someone was playing with 2.3.4 and 2.3.6 stock ROM's in order to achieve better battery performance? I read somewhere that guy had over 4 days on stock battery and 2.3.4 GB. So I wonder if I switch to 2.3.4, which may be probably less demanding system than 2.3.6, will I get more time on one charging? I don't care about how it may or not look like cause I use GO Launcher anyways, but does it have same stuff and functionality as 2.3.6?
The problem with comparing your phones battery life is that it's depending on too many variables. You can't just say 'My phone lasted 30 hours with this and that usage', because everybody is using it differently. If you really want to test it, flash both versions yourself and try.

Can't find "media scanner fix" in the market. Any chance of a link.

In addition to Donnie's very good point, you're asking about 2yr+ old firmware. Do you realise how few people on a site like this are actually running firmware that old ? You'd probably find a fair number of 'ordinary phone users' out there who are still running GB because they may not be technologically au fait enough to do an OTA update.
At the end of the day, changing firmware to squeeze every last drop of battery life becomes a game of diminishing returns in that you can spend a lot of time to get that last tenth of a % of use out of every charge. You have to ask yourself is it really worth it, or is it worth simply enjoying your phone & chucking it on charge every night (or if you really chew through battery, getting a spare).

Well, the thing is I don't understand why people update their phones and then complain about battery life if 2.3.6 works fine from what I observe here and there.?
As per Donnie's post, there's too many variables involved to say 'This Android version will definitely give you better battery life than that version'. Personally, I get better battery life out of JB roms than I ever did out of GB or ICS roms, not that I got poor battery life out of either of those though. And the reason for that is I worked at it.
There's no magic simple A-B-C to better battery life, regardless of what rom/kernel/Android version you're running, you have to experiment & try stuff out to find out what works with the way you use the phone/have it setup.
People who complain about battery life & attempt to pin it on the particular Android version they're running tend to have a really poor understanding of 'how it all works', because it isn't that simple as I've said.

People can also update their phones because of other reasons than battery life. ICS was the best for me with battery usage, but after JB downgrading isn't an option for me as I would miss to many new features and other additional functions.
The choice is yours to make. If you are satisfied now, I would stick to 2.3.6 if I where you. If you are curious about other versions -newer or older- try those
