Hi guys.. ive been flashing all kinds of rom and kernel. In the end i find stock Ics with stock kernel gives me both the performance and battery life i need after removing useless start up and freezing unwanted apps.
Had been using the default touchwiz and suprising theres no lag or redraw or whatever issues. Only set back is i cant customize my stock rom.
Battery life wise i can get up to 6 hrs screen time or maybe more. Will post screenshot after i drain my battery.
On jellybean, batt drain is more noticeable regardless using stock or any other jb roms / kernels. Personally i dont like OCing or undervolting so pls dont mention abt those here.
I am wondering who else here share the same experience with both ICS and JB. Would u still stay on ics or jb?
Would love to hear opinions

Says it all really
I've recently returned to stock rom and kernel after trying warnamlite, miui and a few others. Stock is deco the next for battery. I'm getting nowhere near 6 hours screen time though. How are you stopping apps from starting up? Is this by freezing or have you used another method?

You got 6 hours of screentime with data/wifi on with ICS?
Personally I've been getting better battery life with MIUI on Jellybean, but I've also been using Siyah since the first day I flashed my ROM so that might also have something to do with it. I've had experience with stock ICS and MIUI ICS as well, and the battery drain was essentially the same. I'm running a heavily customized JDUltimate though. If you don't want to undervolt or flash another ROM/kernel then JD is a great alternative. I was using stock GB on my S2 with nothing but Juice Defender and I got pretty decent battery stats, though I can't remember them right now.

Root the phone. Use ES task manager to remove useless startup. Freeze those apps u dont need with tit backup. Btw i never deleted any apps

Hi .. yes approx 6hrs screen time. With only 3g. But i setted my display to around 20% brightness as im indoor most of the time. I usually use the same setup to test among roms and phones as ive got 2x S3 to play with. One of it is my gfs phone. She plays lots of games so i also hear her feedback regarding the roms and kernels i flashed for her.
I find using auto brightness actually drains the battery more with continus use. I also make sure i got only essential tasks ans apps running in backgrd. Btw i have whatsapp in backgrd all the time.
Sent from my GT-I9300 using xda app-developers app
Yeah I have my brightness at the lowest setting most of the time as well, as the only time that I'm going to be in bright daylight is when I'm walking around, and I'm not going to be looking at my phone while I'm crossing the street and whatnot I figured that all of those "auto" settings actually drain more battery because of their constant turning off and on and adjusting and etc...it seems like it would consume unnecessary CPU power.
How do you manage which apps run in the background?

1. Root the phone
2. Install all the apps / games
3. Use ES task manager to remove unwanted startup
4. Use tit backup to freeze unwanted apps.
System apps like mapservice, secphone, samsung pushservice etc that runs in the background are frozen with tit backup and startup removed by ES task manager.
Result : No useless bloat running in your phones background. Better batt life and performance. I can achieve 300mb ram after a fresh reboot. Stays aroumd 400 to 500 range of ram after a day. Will observe ram a day more as i just flashed stock 3days ago.
But so far so good. Quad benchmark scores are a minimum 5.4k too! Will post screenshots on weekend.

(I also had a juvenile chuckle earlier when someone said tit backup!)
So far my experience is in ICS's favour.
Ok. JB is latest. FIne.
BUT TELL ME SOMETHING WE CAN DO IN JB AND NOT IN ICS?
I didnt see even a single sort of such think except some added settings in settings app.
Even looks are same.
We can easily mod the ICS rom to make it look better.
For looks and functions of JB, we can use launchers ofcourse!
And personally, in JB, my ram normal usage was 500+MB.
In ICS, with same apps, its 200-300 MB. How and Why? Both stock kernels.
Also, i am used to playing games while charging. In JB, the battery only declined, even while charging when i played game. But in ics, there is charging instead of discharging even when i play games.
Therefore, jb is mess for me! So unstable with lesser battery....

My first time posting here, so please be gentle.
I've had my SGS2 for around 6 months now, its an unlocked ASIA (as I live in BKK). I noticed on the original stock firmware that the phone was running hot, as in the back panel around the camera would heat up to the point I could feel it in my pocket. This would normally happen if I was using a game like angry birds, or a psx emulator. But sometimes it would happen in the browser under normal conditions. I just thought this may be a issue with dual core phones, so I took this as a 'feature' and accepted it.
But now lots of people I work with have this phone, and it came up in conversation about heat. Everyone stated they do not have this issue, that the phone remains cool all the time.
I have moved between many different ROMs, and have finally stuck with Westcrips ICS ROM. Then a strange thing happened, the heat issue goes away with version 8.4. Phone is cool all the time, even playing my PSX emulator in software mode. Battery also increased from 12 hours to 16-18 hours.
But now I just moved up to 9.3, and its back again, the front screen is very hot to touch when using things like the MX video player, or surfin the web. And if I launch a game ... well, forget about it. The battery drain is immense to, be lucky if I pull an hour of use like that.
Anyone else suffer from this? Hardware fault? I can't take it back because my flash counter is probably in the 20's now, and I can't find a reset JIG in Bangkok.
Cheers.
FYI, I always do a clean wipe, dalvik / cache / permissions.
same issued here, phone bought from Thailand also. Phone getting hot when browser,downloading and playing some games( not all). And its really hot
Changing Rom and kernel sometimes solved it for awhile but eventually will come back.
Looking for solution also
Thanks
P/s: right now im using LA4 stock Rom and CF root LA4 kernel and still get hot

Thanks for getting back to me.
The one I know that fixes it is Resurrection 8.4. Its a dam good rom, and given me the best battery life (once I got 20 hours with normal use). But there is an issue with touch screen sensitivity that makes it annoying.
Maybe its something to do with the Kernel on the Asian models?
If I find a fix I'll pm you.
Hmmm mine only gets uncomfortably hot when playing some 3d games. Didn't experience the same level of heat when just browsing though... It just gets a little warm but far from gaming temps.
What i did was undervolt and underclock when playing. It did reduce the heat and extend the battery though i admit it's not the best solution / workaround.

Well it looks like the ICS kernel is not supported right now under Tegrak. It is bleeding edge.
I tried setCPU to under clock but ended up with a lot of slow down and some full system freezes.
Guess its back to 8.4 until I find a more definitive answer.

Since you're using Westcrip's Resurrection Remix, you can get rid of the triangle by using Chainfire's TriangleAway app - I'm using Resurrection too and it got rid of the flash counter and the triangle.
TriangleAway should work on all ICS roms though.
Strange, installed triangle away yesterday evening. Work like a charm, so I guess if I need to return I can now.

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.

I have serious problem with my Xperia S battery.
My battery runs over very fast and when Im charging my phone and I play a game the same time. I am thinkng of rooting it just to make my battery last longer but since Im new here and I haven't attended to root a phone yet I would be glad if you could answer some of my questions like:
1) Would rooting affect my battery life?
2) What risks do I take?
3) Any other suggestion?
I have tried many apps in the past like advanced task killer (which auto kills every app when screen is off), I deactivated Contacts and installed exDialer and I have reduced my screen's brightness to about 20%. Im desperate because Im leaving in holidays and if my phone continues like this it will probably be a pain in the *bip*
*My search on extended batteries was pointless since XS's battery can't be removed except you unscrew some screws. (not sure about that phrase)
Thanks for time and sorry for any mistake I possibly made!
1. No, but installing custom ROM's may increase battery life.
2. Bricking it, but the rooting procedures for XS is pretty simple.
3. Yeah.
Go to settings -> battery. Whats using most battery?
I also recommend you installing "GO Power Master" from play. With this app, you can see what hardware AND app using battery! Very nice app.
Then close the apps that may eating your battery.
And every widgets on the home screen and in the top statusbar also draines battery. Also make sure autosync is off if u want to save battery.
Good luck!

Wifi cannot increase your battery life...
I'd suggest rooting the phone that way you can uninstall system-apps and uninstall bloatware. Alternatively try stopping unnecessary apps running under options-> Apps. Playing games will greatly reduce your battery life... If I play final fantasy 3 for two hours I'll lose 40-50% battery life! Rooting it's fairly simple... Of course there is always a risk. Ensure you have full battery if you choose to root...

Hi guys! I am new here, and glad to be a part of this big community.
Recently i bought a new Samsung Galaxy S III. The phone was running stock ICS 4.0.4.
Because i am really stupid, and like to make all my gadgets "better", i installed Jelly Bean 4.1.1 Polonia, from Sammobile.
The problem is... THE BATTERY, IT'S HORRIBLE! 3-5% over night discharge, with 30% light, no Wi-Fi, no Sync, only H+.
In a little game, like Doodle Jump, Jetpack Joyride or Jumping Slime, 15 minutes of gameplay and 3-4% battery is gone.
I have the Clockworkmod recovery installed, and i did a full charge and wipe battery stats... the battery got better, but no like on ICS.
What should i do... i would like to install ICS back, but i see that it's kind of laggy, and doesn't got manny features.
I don't like to install a Custom ROM, like Ressurection Remix, AOKP and stuff like that...
Furthermore, on the curent Jelly Bean i was had installed Siyah Kernel and i undervolted my CPU with -50mV, and still no improvement.
What should i do? Back to ICS? The battery life was great in games/aplications...
Thx for any reply!
Cheers!
no, no, no, no, NO!! Best rom threads arent allowed and are not looked upon lightly! Roms are entirely based on personal preference....flash a few and see which ones offer the best battery life FOR YOU!! And its not unusual for games and mobile data to use battery. Its inevitable really dude....

install the app better battery stats, and charge your phone up then leave it to idle for a couple of hours then report back with screen shots of kernel wakelock, and partial wakelock
Apart from that Google now causes some extra drain due to using location services.check what you are syncing (I suggest getting rid of the whole Samsung account/backup set up and disabling Google back up
3-5% isn't really that bad, neither is 3-4 % in 15 minutes of gameplay, considering normal screen on drain is approx 10%/hour

InsertCoin is best.
It haves stock (stable) kernel, full debloat (~100 mb more ram), alot of optional user tweaks, and many behind the scenes mods for maximum smoothness and perfomance
If only people could understand that what's best for Person A, might not suit Person B at all. It's a matter of one's own preference and it's imperative to try roms out yourself.
sigh.... I'm just going to paste my response from one of the many other best rom threads
These best rom threads are getting out of hand...
What's the best rom for me might be the worst for you.. It's subjective.
It's like asking who's the hottest girl in the world, or which sports car is the nicest.. It all depends on the person being asked and if you ask in a forum you will be a different answer from everyone.
The only way to find out the best rom for YOU is to try them all until you find the one that's "best" for you and your needs..

Hey friends I am currently running the OMEGA v28 4.1.1 JB ROM on my international GS3 i9300 and it is also rooted of course and I don't think I'm being paranoid but my battery life has took a massive drop since rooting my device. I am not overclocking mu CPU and I have tried out some rooted apps like battery saver for example and I actually think it made it worse. I have all the usual setting disabled to allow for optimal battery life like brightness right down, auto sync off, wi-fi off when the phone is locked I also only use the wi-fi manually if and when I need it and all that good stuff like smart stay and vibration off. I am wondering if anyone knows of something I'm not trying???
Had it charged to 100% this morning at 9PM and by 1PM I'm down to 79% already and I haven't made any calls and only used it to check my email and facebook for around 10 mins!!! is this normal for everyone else???
:crying::crying::crying:

Sound normal for Sammy JB rom.

Did you reset your battery stats? Charge to 100%, reset battery stats from CWM or delete batterystats.bin -file, let the battery run out.
You might want to use currentwidget to log your battery usage.
I noticed big battery drop between 4.0.4 and 4.1.1 used to get 24 hours one charge 4 hours screen time. Now I get only about 12 hours.

I'm using also omega rom v28, have it installed recently. I cannot say how good is the battery with this rom, but so far I have like 56% in 20h, with 2h screen, sopcast 30min, voice cals 37mins....etc (also using wifi manually when needed)
Try out different roms and find out what works for you.
You can also use an app like BetterBatteryStats to check what's draining your battery. Its just to check whats use power.
Don't use batterysaving apps most of the time they are making it worse
I'm running Omega ROM V27.2 and yes it's normal to have a difference about battery life between ICS & JB.
To improve my battery life I installed the phenomenal extreme kernel, and now I'm totally happy with it. You should take a look to its topic in the GS3 Android Development forum. The dev developed 3 versions of his kernel to fit to most of the phone.
Also as others told you, you should get BBS app to point out the wakelocks & define which app is your problem.
Personally, I'm at 45% charged, and already used it during 21h 10m including more than 2 hours screen on. My auto-sync is always on and my WiFi only when I enable it. I'm using a live wallpaper and a lot Twitter.
When I do nothing I can reach more than 2 days.

Hallo,
I have the OMEGA v28 4.1.1 JB ROM flashed on Thuersday and i´m testing the ROM at a long time.
I use the Phenomenal4.0Medium Kernel and i must say the BatteryLife is very good. I`m working over 15 ours with him and i have 58 % on it.
My WIFI is every time on and Autosync when i use my calender and planners. For me a good app handdling battery life is "GREENPower" in Market Place.
But it´s my idea.

As he recommends ...identifying and reducing your wakelocks should be your primary concern. Been reading loads from developers that the insecure jb kernels themselves should already provide good battery management.
Sywped from my GT-I9300 running Omega v28 & siyah 1.7rc1
i can't get more than 2h and 30min display and 14h stand by. I have tried perseus, siyah and speedmod kernel. Using wanamlite rom.

that is exactly why i reverted back to ICS.........JB is nice and smooth but "eats" battery quickly.........now,battery life problem on my i9300,solved
Hey guys, if you are going to use custom ROM's you should be prepared for bad battery. The developers are adding so many different features and hacking certain apps to make them work in their ROM's without a lot of investigation into what the reprecussions to battery are. I used to always use custom ROM's but haven't installed one in about 6 months and haven't any problems with battery life. I have the latest JB on my 9300 and battery life is very good. I use GSAM to watch apps that want to go rouge and start sucking battery life. Media Player Service is a big offender as is Facebook. Also stock widgets that get placed by these JB ROM's are always pinging for new data and kill battery quickly. Get rid of them! If you have a stock ROM and are getting bad battery, 99% of the time it will be bad apps, your job is to determine which ones they are and apps like betterbatterystats and GSAM work great to help diagnose the issue.
can anybody else confirm the above post? because i am not sure about the custom roms.

I will soon have an S3 so I cannot speak specifically about this device / ROM(s).
What I know from using a lot of Android devices and testing original ROMs vs. custom ROMs:
- original ROMs have too much garbage built-in apps and are slower
- original ROMs have everything working
- custom ROMs are much cleaner and faster
- custom ROMs have (too) much problems, something always not working 100%
- custom ROMs usually have stability & battery issues
My personal advice:
- install latest ORIGINAL ROM.
- root it
- install the free app "App Backup & Restore" from Google Play
- search unuseful apps from Samsung (& others) and block the autorun of these apps (note: do not block basic android or samsung apps, as phone, contacts, etc)
I use this method for 1.5 years and this way my Android is clean (you can save over 100-150Mb RAM), FAST and much better battery. Try it.
In the end, if original ROMs have too many original apps, custom ROMs have to many tweeks that in the end, for my taste, the original ROMs + App Backup & Restore win hands down.

I have always had custom roms on all my android devices but at the moment I am running stock ics in my s3.
I don't think the S3 needs it.
To be honest I find a lot of the stock based roms full of changes I don't really need, ARHD was a great Rom but recently has started to lag really badly for me (and some other users) so I went back to stock just to see and so far I can't complain. Smooth, fast and the battery is as good if not better than the custom roms.
If the camera didn't suck so bad on AOSP I would be there in a instant
