now when i had my xperia x10 it was a clear difference between
the stock rom and the custom roms. without the custom roms xperia x10 is garbage before and after gingerbread.
now i got this s2 4 days ago. this phone is crazy fast, never like ever really lags for any reason. and my battery will get me thru a full day easy, as of now.
so i would like to know any real significant differences in speed or any real benefits besides customizing the look of the phone by rooting and enhancing?
i know the general reasons to root android, but this phone in particular i would like to know what i can significantly get from this as i dont see how it could get too much faster lol....
please and thank you?

Features. Custom roms will add features that won't be available in the stock rom. Some of them are themed, and have themes available. Debloating may also offer improved battery life.
If you decide the stock rom is fine, obtaining root access adds to the functionality (gives you more power to mod, as well as certain useful apps that require root access).
You could also get on the deodexed, stock rom. This makes it easier to theme and modify system apks.
Well, on UCKH7 - if you don't want data overages you need to root in order to nuke the AP Mobile widget.
You can improve battery life a bit by debloating other stuff like SNS after that.
The stock UCKH7 ROM is pretty decent, not "garbage" - but there are obvious fixes available.
I may have never rooted my SGSII if I had not received the OTA upgrade to UCKK6 (2.3.6) which caused terrible battery life. So I rooted to return to stock UCKH7 (2.3.4) which improved the battery life.
After reading many threads on this forum, I wanted to tweak the battery a little more so I flashed UnNamed 1.3.2 which removed the AT&T bloat and improved the battery a little more.

yea ive seen the complaints about 2.3.6 but its clear that it isnt everyone. a few others, including myself, have not had bad battery issues with it. just earlier today my phone was on 100% for 2 and a half hours. and then after about 5 hours of use i still had 76% . not the greatest battery but it's fine.
i read somewhere that reverting back to 2.3.4 breaks wifi ? is that true ?
i wanted to go back just to see what battery life was like.

The UCKK6 update has several bugs that UCKH7 does not. You're right, the wifi battery drain bug doesn't get everyone in a big way, but those it does really suffer. It gets others in a small way though. Also, bluetooth hid is completely broken on 2.3.6.
Reverting to UCKH7 without doing a wipe data/factory reset will break wifi, so if you revert, you must wipe. But you should always wipe when switching from one version to another anyway, except the ota update of course does not require a wipe, but they do that incrementally.
Quick question about debloating, i used root explorer and went to data/apps and found all the at&t crap, got rid of it, but after a factory reset, they are back.
i looked into the System/apps folder and they were not there so i don't know where else to look.
thanks

The problem I had with the UCKK6 bug was that it was intermittent. Some days I had good battery life and then out of nowhere the battery would just start to drain and of course it would happen when charging wasn't available.
If you decide to go back to UCKH7, I would strongly recommend you read the step by step guide by creepyncrawly in the General forum. It will guide you so you don't Increment the Flash Counter.

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!

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 decided recently to do the OTA update to 2.3.5, and since then, I've been getting terrible battery drain. Overnight, I lose a few % per hour. I have to charge the phone everyday even if I don't use it. It says Android OS is draining most of my battery. I haven't noticed any significant improvements from 2.3.5, but I've noticed a few annoyances, like when I press back out of an application, it doesn't close it. I have to use my task manager.
Anyone know a fix to this without putting on another ROM/Kernel? I haven't done that since my Captivate, and I doubt I'm adept enough to do it at the moment.

No.
The battery drain is a fairly common complaint with the 2.3.6 OTA update. As far as the back button, I havn't seen that mentioned, and I did not notice the behavior during the short time I experimented with the OTA update.
Your options are, 1) flash Entropy512's latest (12/21) daily driver kernel to see if this will stop the battery drain, 2) go back to stock UCKH7 and aviod the update, 3) flash a custom rom.
Flashing a custom rom is the best option in my opinion. There are guides to help you step by step.

I've been reading up a lot about custom ROMs, and more often than not CM9 always gets a mention. I'm tempted to flash it but just wanting to know is it really worth it? Does it have major improvements on battery and performance, and what are the main things that make it so much better than the stock ROM?
Also is it easy to revert back to the stock? I've already got my phone rooted with CF-Root, is that the clockworkmod recovery I've read about, and if so can I just go ahead with making a backup and flashing with CM9?
Any help/info would be appreciated.

Its users choice read what does not work first .
CF root is not Clockwork Recovery but it probably has CWM recovery incorporated .
CWM manager in apps and boot to recovery should show CWM options .

CM9 is experimental and still has several flaws and issues.
I'd not recommend it for everyday usage if you're not a developer or like living on the edge.
Plus, 3G battery life is terrible since CM9 has no Fast Dormancy. Within ~5 hours the battery was always dead on me.
Samsung-based Roms make it more than 24 hours in contrast.
It will of course get better when the ROM is properly fixed and all features integrated. It always does =)

a lot of the battery issues are due to not resetting battery stats. You fully charge the phone, clear the stats, then charge it again I think? Search there are instructions.
I've got CM9 on an Atrix which isn't even a supported device and it's totally daily usable. The only things I lose which are only b'cause it's an atrix are:
Fingerprint reader
Webtop
video camera
Check out what works and doesn't with CM9 for your phone and decide. I like it a lot, it's TOTALLY stripped though, like no google aps (you can install them as a package)... There are lots of weird intricacies to it but it's cool as hell IMO

It takes some time for the developers to get it right on the S3. I've never said CM9 itself had issues, it's the combination of CM9+ i9300 that needs some serious work.
I have or manage a couple of CM9-flashed devices (from Galaxy S1 over Galaxy S2 to Motorola Xoom) so I know how awesome the Rom is =)
Cheers for all the replys.
Are there any other custom ROMs worth looking at? I've heard CM9 is the most popular but if it's not quite usable daily yet I might give something else a try.
CM9 is currently very usable. I have no problems whatsoever. It has many advantages to stock ROM like no low free memory problem, no launcher redraws and no lags. The only real disadvantage is that the camera app sucks compared to stock.
It must like your phone better.
Kept turning off the modem for no reason, sometimes restart was necessary to connect.
It also has no fd as already described, so many people will notice a huge drain in 3g.
Btw you can easily get rid of memory issues by freezing/removin, all the apps you do not need but which are always running.

Hello
I updated my Galaxy S2 via Odin(PC) from Stock 4.0.4 to Stock 4.1.2. All went fine, phone works smooth and fast. But there was a massive battery drain. Therefore i wiped data/cache, did a factory reset, everything is new an fresh. Phone still works smooth and fast but battery drain doesn't change. Take a look at the screenshot. Is there something i can check and change?
Thanx in advance.

Chill let the rom settle for a while, the battery is usually weird after a flash use it for a few cycles and then it should be alright

Thanx for your reply. But i cannot confirm that. Never had such a behavior. Flashed a few ICS 4.0.3 and 4.0.4 Roms and either thery're draining or not unless i'm able to change or fix somthing. It never improves on its own. Maybe it's my bad luck only.

I;m not talking about the specific rom thread I'm speaking in general. We have plenty of Q&A/general topics about battery drains etc have a good search and read.

Yes i will.
But, generally, flashing different Roms causes different issues. Reading solutions based on different ROMs, Custom ROMs, etc. isn't very helpful. There may be general solutions for this damn battery draining problem. But until now nothing fits to me.
In the end i hope to find a solution or i will go back to ics.
Have a nice day

Your absolutly right, i read many problems, but with those stats are weird.
1) Just try to re-flash the ROM and after go to recovery and clear everything(dalvik, data etc).
2) Use the option to reboot.
3) Turn off phone -> remove the battery -> Try to turn the phone ON without battery one or 2 times -> wait 2-5minutes more without doing nothing -> Battery back in.
4) Charge up to 100% (when the icon appears).
5) Wait for 1-3 cycles and check if its ok.
6) If you have media draining check my signature link.
Issue solved, probably
I probably solved my battery drain issue while doing what CrisR82 suggested in his post here:
http://forum.xda-developers.com/showpost.php?p=37227296&postcount=10017
" Battery drain is caused by a permanent wake-lock (I had that issue).
For everyone with that problem, here's what I did and got rid of it:
1 - fully drain your battery (0%, to the point where it won't power-on at all)
2 - recharge your battery without turning on the phone
3 - go to recovery mode and wipe both data and cache
NOTE: backup all your contacts, messages, whatever...this will delete everything!
(I formatted my USB storage aswell before step 1, but I think that's not necessary)
No wake-lock for me, 17 hours use, 12% battery down (only checking the clock every once in a while)."
As it seems it worked for me also. Did it yesterday evening and keep in mind i did a factory reset therefore i had to reinstall everything. Battery is behaving normally again.
Maybe this helps the one or the other.

Now, right solution
Ok, my mistake!
At first it seems that there is an improvment in battery life like i said in the above post. There is ... but slightly. Not enough, not acceptable at all.
To make it short.
I did a clean install. That's it. Wiped everthing, pumped the battery up to 100% and flashed Samsung Stock jb 4.1.2 again. And it works now.
Thanks all for your advice.

I can confirm this.. I also did full data wipe on ICS 4.0.4 then flash to 4.1.2 JB and again full data wipe after first boot on 4.1.2 JB..
My first battery cycle went up to 2d 11h 34m 12s.. now im on my second cycle.. so far is 61% 1d 2h 39m 24s..
I hope this will help.. :fingers-crossed:

Me again.
My battery drained in 21 hours even after reinstalled everything after a full wipe. Couldn't find out what process caused the drain. Used bbs and its stats say android os, screen and Android in sleepmode is using most of the battery.
I'm back on 4.0.4 now. Waiting for next jb version.

Thought I should share that I tried the same and face the same issue. Before JB, on completely stock 4.0.4 (no root), I would charge after three full days (72 hrs). Moderate/normal use - no heavy gaming. Under JB it drained in less than 24 hrs with very moderate use - mostly idle. Back on ICS i now get the same battery time as before.
I should add that my phone came new with ICS 4.0.4 installed. Two friends of mine have upgraded theirs all the way from GB -> ICS -> JB and they exeperience significant battery improvement. Being a noob, I don't understand whether this makes any difference. Simply coincidence?
All the best.

New ROMs are always smoother than previous ones, once you flash em you get in cant-put-it-down mode. You need at least 1 week to judge battery life on any ROM. A couple of days to set it up and a few days to see how it behaves.
Once you get things going you never go back, that's a fact.
Be careful on 4.0.4.

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
