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.

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.
Regards.

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!
why i have worse battery life? I have the 2.3.5 from samfirmware.

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'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

there are other tweaks with custom roms that aren't found in the stock rom (which provides better functionality).

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

That is wrong. I used to have a UGKG2 ROM and since I upgraded to XXKH3, the battery is MUCH better while the GPS pinpoints in less than 3 seconds with a 5meters accuracy.
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.

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.. my first experience with S2 has not been great battery wise. I've found the battery life to be horrible. Even with all the battery saving features i.e. static background, widgets off, etc. etc., I have to charge the device twice a day. Its practically useless. I was thinking maybe there's some 3rd party ROM out there which would improve the battery life? I'm currently running stock 2.3.4. Any suggestions would be welcome..
try mikimod"s rom its really good for battery, and also sicopat<s rom< and modaco i find they are the best for longer battery
I've used VillianROM, Cognition, and CyanogenMod. I find that CyanogenMod gives the best battery, but your mileage may (or will, most likely) vary.

Now that I have bashed your face in. I get 40-50 hours out of my phone. Try GREEN POWER from the market. It turns your data off when the screen are off. Also See my sig for what I run.
Hyperandoid1.3.2 with speedmodk2-1 gave me a battery life of over 2 days.

You will get mixed answers. People run different roms with different kernels. Some do a full discharge/charge before judging these kind of things, some don't. In the end the most important factor will be apps and usage.
Try what works best for you. And post in q/a section next time.

Best Rom So Fare.........
( SensatioN Rom 1.8 )
( Based on 2.3.5 XXK13 )
this is none wipe Rom.
Excellent review..
Try It..
Hope you'll Sensation Rom.
Before trying other roms/kernels check to see which apps are draining your battery so much, as for dual core phones the GS2 battery is really good, so in normal situations you shouldn't have to charge the battery twice a day.
I'm in Wanam 5.1 + siyah kernels and as many other users i get +2 days of battery.
@antiochasylum I've hardly had the need to post. In any case, any moderator can feel free to move this thread to General. @Sesshou about 57% is display. Rest of the entries are all negligible. Yet the batter evaporates..
Why no one mentioned MIUI ROMs..?
Are they not good in terms of battery life..?

Use your phone less and/or plug it in.
P.S. If you think this is a vague response, I think your request for help was vague. When you go to the doctor and tell him/her you have a pain, what happens next?
And there are umpteen posts on this topic already ffs
HERE THIS ICS CUSTOM ROM DID THE TRICK FOR ME

totally agree with ZACQ8
You can get a 2450mah battery that doesnt need a different case. Also try Android Assistant, you can view processes that are running and sort by cpu usage. Try to remove or atleast kill from startup any apps that do not need to run all the time. Most battery assistant programs do not work as after killing an app it will just load back up a few minutes later.
I got the official 2000 mAh battery which did give 15% more life. However the most effective improvement I got was from using the SpeedMod kernel and using Tasker to be more precise about when things came on.
Went from around 14 hrs stock to 30+ hrs for SpeedMod on stock rom for GB.

Hi,
To avoid too fast draining, some classics advices are to turn off some functionalities when you not need it, by example Auto Sync. Many applications needs to be configured with less frequent synchronization (weather apps or widgets, email apps, news apps...)
And as it was mentionned, some kernels can dramatically improve your experience. I agree that Speedmod is one of the best kernel to preserve battery. You can flash it easilly via CWM.

Okay so I've been messing around with roms lately and I'm somewhat a flashaholic lol
But now I'm really looking for something flexible but GOOD on battery life.
What Combo is best for battery life?
such as Modem & Kernal (+ Rom)
I'm currently on this (at the moment):
Rom: MIUI V4 (360 PRODUCTIONS)
Kernel: 3.1.10-subZero-1.6 End_of_Line)) #167
Baseband Version: T959UVKA7
My battery life isn't really too special, I have wifi on, 3G preferred, auto brightness, sound on high. . .
85% - Discharging 2h 5m 30s on Battery
Any ideas on bettery battery life or is this pretty much good/normal?
also my battery isn't a samsung battery its an MYBAT 3.7V LI-ION Battery VLN-08 1200mAH . not too sure if that plays a big role in this.
sidenote: TWS IS ONLY 4%.

I'm going to make an assumption here, and perhaps it is an incorrect one.
I've installed countless ROM's on my Vibrant, and I've had mine a VERY long time (got mine the week before the official launch...long story).
I've found no roms that match the overall battery life of Samsung 2.2 froyo based roms. It is for this reason that, though I've tinkered with practically every single gingerbread, ics, and jb rom ever released, I always go back to my personal favorite as a daily driver. Project V w/Bali 1.8.8 kernel and KB5 baseband.
My assumption is that the "black box" effect is at play. Getting the last baseband available to us (KB5) to happily play with later builds of android has always been an exercise in frustration. Sure it has been made to "work" with later builds, but given the closed nature of it it's clear it just doesn't work as seamlessly well with anything else.
My battery life with 2.2 based roms has always been way better than later android builds, often lasting twice or more as long.
Thanks for the link I'll take a look at it.
@masterotaku : Everyone says Froyo has the worst battery life ever :\ but I also believe what works for my phone may not work for yours, and I do know Froyo is a very stable rom it was the rom i ended up going back to and sticking with on my MyTouch .

Slim bean with stock kernel getting a full day with moderate usage and one thing I took the Samsung 1650 mah battery but don't know how much difference it makes but happy with slimbean

The best thing I ever did was to buy the Anker 1800mAH battery for my phone. Probably due to the fact that the stock battery is getting up there in age as I'm sure everyone's is. I recommend everyone buy one.
