Hi..... I just wanted to know if the rooted stock Rom has better battery life than the regular unrooted stock because the regular stock kills the battery really fast.

Rooting by itself doesn't do anything so...
No
i thought stock battery life was good. Maybe it is something running in the background that is killing your batter.
Being rooted you can remove a lot of bloatware to save battery life.

All superuser (root) is is a program designed to grant applications admin access to the device, rooting itself inpacts performance/stability in NO way whatsoever..
if you want better battery life, i recommend flashing a custom rom

which gives you access to remove bloatware... did you miss that part? If you strip down your phone and freeze/uninstall apps that ran in the background and/or used data when you don't want it to, then you will improve your battery life.
I think you fail to see what the OP was asking. it was about battery life, not performance or stability.
if you check the running applications and freeze the ones that run all day then ya better battery but obviously just rooting isnt gonna do it

Im with doug on this one, i think youre taking this too far. The op inquired if a STOCK rooted rom had beyyer battery life as opposed to a unrooted STOCK rom. As doug said, a rooted completely stock rom offers no battery life imprpvements on its own. Now performance to me is defined as the optimal battery life and efficiency of the device.

Darksides and Juggernaut are the pretty much stock with bloatware removed and some additional goodies which are super helpful such as the notification bar toggles. I'm currently using darksides and I'm seeing very good battery life on moderate use (2 hours display time at 50% brightness, 1 hour on Spotify streaming music and I'm down to 30% battery. Total uptime since last charge 13 hours 51 minutes.) Perhaps not the best battery life out there but it does the job for me. Also if you're gonna install either ROM, undervolt the cpu as well as underclocking it. It really doesn't affect the performance, its hardly noticeable actually.

Ah i see what you guys are getting at. Just misinterpretation of both parties. Yes rooting itself does nothing, but obviously something is killing the op's battery. I was trying to inform the benefits of having root and how it may improve his battery life by removing whatever is killing his phone.. However if it's from an app he uses then no help there.

If you want better battery life you can always try change the kernel first. You don't need to do pesky full wipes so you retain pretty much all your settings and stuff.
To start off, I think Faux's is pretty awesome.
You're not going to gain leaps and bounds in battery life until you find what is eating all that power on your phone. It is typically an app you installed, as I don't find the t-mobile pre-installed ones to be that horrible, except for lookout security. I think that'll be a big potential battery hog. OR it can simply be your screen brightness. The trick I find is to set it on the lowest setting and just be SOL when you're outside I mean heck, I really want that battery life!
You can always practice better battery saving techniques, like not leaving the wifi or wireless data on when not in use.

What would you say is the best battery saving kernel? I need to go a days worth of battery , and I use my phone heavily.
I use jd mod 102310.
I'm currently testing kings cfs#8 but its dying fast why? I just loaded the rom after a full charge.
How long will the battery life start to kick in?
Please help me.
Advice is needed.

I don't expect to convince anyone to go back to stock, but the newer ota updates and roms have fantastic battery life. I can't say that I have noticed any difference in battery life with the 3.30 but I haven't taken he time to observe. But 3.29 was a big improvement, or so it seemed.
I go about 40 before charging. And I'm a heavy user.

Not even Cauks or blazer el29 doesn't give the battery life as stock.don't get me wrong they are all great roms but at least for my device not battery friendly. I'll post some battery stats from BBS if anybody has some free time to see what's going on. I'm on Cauks el29 now.I format everything before flashing and I use cauks format all many times.

Well when is the last time you used stock? And if it's been quite a while...consider having your battery checked out. Anyway, I'll continue as if your battery is fine from here on out. Basically, anything but stock tends to have a modified kernel. Even with all the battery tweaks, etc out there, there's a chance that the kernel itself might not play well with your phone. I'm not too versed in that, but I also noticed that the TouchWiz based ICS kernels/ROMs give MUCH better battery life than AOSP based kernels/ROMs such as CM9 and AOKP, etc. This is just basic stuff you might already know, but yeah, just go on and post your battery stats, preferably with a custom rom and a stock rom so we can see the difference and where it lies. Also, I'm running Touched by a Galaxy S3 on my phone and with moderate use (music for maybe a few hours a day, texting, don't really make many calls) I average between 8.5 and 11 hours from 100 to 0. Another thing I'd suggest is download CPU Spy from the Android market, or something similar if you prefer, and post screenshots from that on the custom ROM; the problem with AOSP and certain other GB and TW ICS roms that i've seen is that something prevents the processor from going into deep sleep mode, usually keeping it at 200mhz or higher. Lastly, when you use the custom roms, do you notice the phone getting really hot compared to the stock roms?
I'm assuming you know this but are you letting the battery cycle a few times before passing judgement? I usually spend a week on a rom before I decide if I have good/bad battery life... attached screenie is normal for me with moderate use on mijjhs goodness rom

Agree, everyone have different experiences, I haven't try that ROM yet, I will test it out later. Have a nice day/night sir.
Sadly I have to agree with OP.
And the previous screenshots at 59% with 1hr, 36 screen on is exactly the issue.
Hard to compare your battery stats with mine since screen on time for my phone will be 4+ hours.
Since there are no standardized testing anyone can do with any rom, any speculation on which rom has better battery life or doesn't is just pure bogus seat of the pants gut feelings.
If there were a standard test that ran like. 5 minutes of mail with 20 mails received, 10 minutes download, 30 mins of playing the exact same video, 13 music tracks of the exact same song all with screen, vibration, brightness, etc all at the exact same level, you could get a real test, but, alas, nobody has a standardized test.
For MY usage, stock clocks in at the same as or better than just about any other rom I've tried, including all the various super scripts out there.
I guess I just overuse my phone!

Things drain battery. This is my test off wifi for the most part using the phone as a phone with average use. Didn't even log in to Google on this one. Just proof that intensive applications, google services, and anything else added after a "factory flash" can manipulate battery life significantly.
Oh, and check out drain when I'm in less than ideal coverage. Noticeable difference. One huge factor to consider when diagnosing battery life.
It really depends on what you're doing with the phone. Obviously having brightness up playing heavy games with Wimax on will kill battery faster than someone on low brightness reading an ebook with wifi on. That said, i agree that I've had better battery life stock than almost all ics roms.

Truth to the last word.. I hate battery life threads too many variables.. I love the part about " using the phone as a phone " you crack me up B..:laugh:
I know alot of people ask which is the best combi, but i dont care about that.
im wondering which one really affects the battery more, the rom or the kernel?
im looking for more battery life and i constantly try many roms and kernels to find the best, but its all very erratic so im wondering which one i should change and look for increase in battery life more

99% of the time it'll be the kernel that changes your battery life (exception being if you're running a poorly written ROM, which is unlikely). Kernels give you the ability to tweak your phone for better performance or better battery or any combination of the two, whereas ROMs more or less just change the user interface. I have gotten pretty good battery life on Tiny's kernel, so you could try that, but you could ask 20 people, and you'll get 20 different answers for the best kernel haha
Yep its said kernel affects battery. My experience over a multitude of android devices says neither have a noticeable effect on battery life. I flash kernels for other reasons, not battery life. I've always gotten similar battery life on stock setup vs any combination of ROM/kernel. Maybe SLIGHTLY less battery if the kernel was geared for performance, but never have I seen a noticeable increase in life.

i was using AK kernel and my battery was dying in a matter of hours. Ive been using Trinity and I've had great battery life.
I have a ROMed Galaxy Note 2 and the battery life is amazing. My son on the other hand has a stock Galaxy S3 and it's the worst battery life I've ever witnessed. It's the typical draining while in standby issue reported by many S3 users. Bottom line, his phone is getting a ROM tonight before this phone melts down. Problem is, which one do I choose? There are so many and it would take me months to read thru every post to determine which one is right for him. So for now I'm going to focus on what really matters most, battery life.
Which ROM have you read about or used that you feel is battery life winner?

We are lucky to have MANY great ROM's out there. There are so many great devs here that go out of their ways to make the experience better. I highly suggest trying as many as you can, because each phone, after much experience with my ROM's, are different. Make a nandroid backup and try a bunch! What I'm getting at is that there are too many well made ROM's here to pick one. Flash away. Oh and make sure you turn off google now cards and locations...that will drain your battery like no other on this phone. Best of luck!

For longest time I was swearing at CM10 / CM10.1 and than I found a thread about what affect battery and now both TW and CM based roms that I use are about the same...
To get great battery life follow the simple rules:
- stay away from colour. The darker the theme / icons are the better the battery life. Some go as far as to get inverted gapps...
- no live wall paper. It will affect battery life... yes, the darker the wallpaper the better the battery life...
- turn off GPS , bluetooth , nfc and everything else that you don't need... turn it back on when you need it...
I have 15 toggle mod and I even turn off data when I don't need it. (I turn it back on once every couple of hours to get e-mail and notifications... than turn it back off... this also prevents rouge apps from dialling back home to mothership...)
- if I travel from one location to the other I toggle airplane mode on and off... this forces modem to look for strongest tower... the strogner the tower the less power you need... hence less battery consumption...
- Use Ti Backup on roted rom... unistall what you obviously don't use..
- Google apps that run that you don't know what they do... stop or unistall those that you don't need...
- Use fierwall... block everything that doesn't need to talk to internet ... less you use antenna longer the battery life...
Also, if going to new ROM wipe battery stats and let battery fully discharge couple of times. This helps as well...
Follow these simple rules and don't be surprised if your battery life doubles regardless of the rom...

While most of this makes sense, I have to disagree with discharging the battery fully. This actually reduces battery life drastically.

I agree but idea is that you let the kernel optimize it by itself.
So you do this only a few times on new rom and that's it...
As for myself I tend to plug in the S3 to charge as soon as I hit 60-70%...
(whenever I can of course - i actually keep one charger at home and one at work)
SIDENOTE:
Forgot to mention the widgets... to me they're just short-cuts and if you set them for automatic update (weather being prime example) they'll just waist battery and bandwith... (it takes about 1 sec to turn on the data from 15 toggle mod and 1 more to start the app I want updated - email weather whatever... to me this is a small price to pay for extended bat life...)
If I may toot my own horn, how about this guy getting four days from one charge with my ROM and ktoonz's kernel? http://forum.xda-developers.com/showpost.php?p=36384974&postcount=95
Your mileage may vary but I usually get about a day and a half or two days from one charge with the stock kernel that's included in the ROM

I can't possibly be the first one to create a thread about this. Yet I have been searching and can't find it. So here I go.
I obviously have a T-mobile GS3 T-999. I was on stock unrooted 4.1.1 just fine with great battery life. I updated to 4.1.2 stock unrooted and now my battery life is terrible. I can't even come close to lasting all day like I could before. My habits haven't changed. I haven't installed anything else since they update. I have rebooted and power cycled several times, no change.
Anyone else have a reduction in battery life since upgrading to 4.1.2? Is there anything I can do without going beyond the usual? I have been using power save mode since I bought the phone. So it was that way before and after the update.
Rooting and flashing a custom Rom will increase battery life tremendously. If you don't want to root then disable all the bloat ware. This will speed up phone and increase battery.

Haven't been able to get awesome battery life on my end either. Played with all kernels available even going backwards to kernels I know gave good life on 4.1.1... Something internal is causing it, it seems. I don't get wake locks that I don't cause my self, just battery drops faster now compared to what it did before.
Sent from my SGH-T999 using xda premium
I suspect that the premium suite, which added multi window and a bunch of new apps and features, is probably causing the increased battery usage. With the increasing amount of bloat Samsung is stuffing into their ROMs, decreased battery life is expected.
The life on 4.1.2 is terrible over all not sure why best bet would be routing flashing a custom rom or you could try playing with kernels but those are tricky business. I feel 4.1.1 Roms get the best battery though I'm on 4.2 and not very good battery life on that either

Yeah I'm not really liking it much. I would do better on 4.1.1
These are my results on Stockorama v2. Stock Kernel.
I don't think it's that bad but I wish it was better.

That's actually quite good compared to what I get with the latest CM 10.1 nightly.

That's terrible on both accounts lol. I usually get 18 hours with that battery time. I remove all the bloat I mean all of it. I have maybe 20 apps total in my app drawer, I disable all the sync besides contacts, gmail, and calender. But still have drain. On stock kernel it was bad and deep sleep was hardly achieved with no apps running in the back ground. I'm gonna Odin root66 md5, tomorrow and see if it helps. Other then that I'm going back to 4.1.1. I'll report back tomorrow or Friday with results.

Well, I don't plan on rooting or using a custom rom any time soon. But I am hoping to find out what I can tweak to get my battery life back to what it was. I am guessing I don't have the option to go back to 4.1.2 using Kies. And I hear that 4.2 has poor battery life as well, so now I don't have that to look forward too either.
I'm on Stockorama V1 and still had 50% battery when I went to bed this morning (I work nights). The first day after I flashed it the battery was pretty bad, mostly due to wake locks from the Media Server, but that was an easy fix with an app from the Market. I would actually say my battery life is a little bit better now than it was on 4.1.1.

I don't know if Sammy ever solved it, but iwith past updates the media scanner would hang up and drain batteries quick. Some had their phones heat up.
Another culprit can be that when going to a different android version, it may handle some data differently, causing hang ups when it runs into something they didn't plan for.
In either of these cases, its best to do a full wipe (backup first) and then reinstall your apps. Don't restore them from backup as that's just like not wiping in the first place.
Then wherever possible, import your data through the app itself. Not many do this but some do. Contacts is one.
I know it can be a pain, but it can help a lot. Plus you wind up cleaning out stuff you don't use or need anymore.
I always wipe data when updating , unless its to the same android version (4.1.1 to 4.1.1). Going to 4.1.2 shouldn't be to big a deal, but you never know.
Another thing to try:
If you verify media server/scanner is a oroblem, copy all your music, pics, vids, etc to your computer and wioe it from the phone. Then reboot and wait a few min to see if its acting ok. Then copy your files back, wait a few min and reboot again. Hopefully it'll calm down after this.
Hope that's more helpful than confusing!

You wonder why carriers take so long to release an update because usually people would start complaining. It's not 4.1 so don't expect the same thing, usually when there's an update things are the never the same. It was the same thing the jump from ics to jelly bean, when creating voltages for batteries I don't think companies anticipate all the extra stuff a update can bring this is still kinda of an ics phone.

My battery life went up so much. I'm on stock but rooted. I usually drain my battery before the day is over. Now I'm going over a full day.

I was able to get 32 hours on average with CM 10.1 and KTunez kernel. I recently switched to the Stock latest TW and I'm seeing 22-24 hours with the KTunez kernel. I am rooted and removed all the bloatware.
I'm running stock rooted for now. I hardly have even noticed any battery drain on my phone. Stock Battery, nothing really battery-heavy, no customer kernels. However I dont really see the use of this Sidebar thing. Its like
HAY GUIZ LETS PUT THE UBUNTU UNITY BAR ON ANDROID HUEHUEHUEHUE SO CLEVER!
But in all seriousness, I seem to be running just fine. So I cant really vouch for Multiwindow being the culprit. I may run some tests though.
I don't remember what it was before. But usually by the time I went to bed, it was in the 40's and sometimes the 30's if it was a heavy day for me. Now it drops into the teens.
I see that as of today, the phone has been discharging for just under 4 hours and is already at 88%. And I haven't even used the phone in any way today before checking it right now. Shows "Google Services" as 41% of the battery use. But that only shows CPU total at 33 seconds. Next item is "Device Idle" at 15%. So I don't understand why it's down to 87% in 4 hours of basically doing nothing.
Though I don't think that info alone means anything to me right now as I don't recall what that info was like on 4.1.1, only that my battery % by bedtime is significantly lower than when on 4.1.1
I was just curious how many other Tmobile people experienced the same thing when going from 4.1.1 to 4.1.2. All stock that is.
I don't have time to deal with wiping the phone clean and starting over. But I may try that someday. My phone never gets hot and I never see the CPU getting much use at any given time.
I do wonder about facebook though. I think it also did an update of it's own around the same time I did the 4.1.2 update. I will check into that.
I have found battery life to be about the same, at first it wasn't that great but now I was able to get over 2 days with minimal use 4g on all day. With normal I use I still get better battery life that 4.1.1

I am confused. So it wasn't good and then it just became good over time? Or have you made some setting changes?

Well when I first updated it was stock and battery life didn't seem very good but I've since flashed a custom rom and all is well. Also I think stock rom got better battery with use, maybe had to settle in? But within 3 days of using 4.1.2 my battery was back to normal again.
