Battery life poor except for stock

I give up.every ROM I run just doesn't have the battery life expected. Am I expecting to much? 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. I'm on the verge of staying on stock roll my eyes.

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

I always had faster battery drains on ROMs than stock. I see all this awesome battery stats screenshots but noticed they all share one common factor, only 1hrs to 30min screen use. Come on guys why I would want that battery life if to get it I have to barely use the phone makes no sense to me.
"hey look my awesome battery life, 1d 25min" (35min) screen time" pffffftttt :what:
Sorry for the rant. Had to let it go outside.

Btw: this post had nothing to do with the screenshot before this post. Trust me didn't notice it was there till after the post. Lol

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.

Best ROM for Battery and Data Use?

I am sure this has been asked, but I really need some help with this. I am using fully 4.1.1 STOCK and I do use the data on my phone quite a bit, but I don't see how after 6 hours, my phone is completely dead after a full charge. Screen on time was roughly an hour and a half! What is the BEST ROM with the best Kernel even, for battery life and extensive use of data?

The max I could get waas 2 hours screen on time, 3G really hurts your battery, I don'think theres anything that can change that

stock is always best.

No I don't think so. Are you using the Verizon or GSM version. There must be something with your phone or the settings, possibly a wake lock issue. With the GSM version and 2000mAh battery I can pull 3-4 hours of on screen time, using roms like AOKP and Franco Kernel. I turn off data, wifi, gps and bluetooth until I need them.
Can you go into Settings -> Battery an take a screenshot. Then press on the "battery graph" to reveal the history details screen and take another screenshot.
Not sure if it work with stock, but holding the Power + Volume down button should take a screenshot.

Every bodies phone acts different with certain ROM and kernel combinations I have had good luck with lean kernel but that doesn't neccassarily mean you will

For your display brightness, you may want to install Screen Filter. Its in the market. Especially without having to tinker with the display settings it lets you dim it down even lower than the lowest setting. Also great for movie viewing in a low/no light setting.
I think this requires root, but you should try Better Battery Stats, select partial wake locks since charged, and see what the culprit is.
CPU spy would also be a good one to see what frequencies your cpu is running on the most.
I'm currently on liquid beta 1. It seems to hold battery quite well compared to cm10. I also use trinity kernel, and the TKT app.

[Q] Juice Defender & CM10

I know it is still early in the game, but has anyone used JD with CM10 long enough to say if it worth installing? Does JD help or hurt with CM10?

I tried it for a bit, but it didn't seem to help. One thing I noticed with the CM10 nightlies is that my battery life is very inconsistent so that makes it hard to really determine the effectiveness of JD at this time.

Yeah, I'm also undecided. Ago I've been using it in the basic balanced mode mainly to turn my WiFi on at my house, but I think I'll try leaving it disabled for a while and see if there's a difference.

I've been using JD with CM 10 for a few weeks based on how awesome it worked with OnlyOne ICS Rom. JD does save a lot of juice when the phone is idling by turning off UN-necessary back ground activity. But, I do find with CM10 that it periodically causes a crash of the OS that requires a reboot through the three finger salute. Not sure what the root cause is as it took Mr agile to isolate JD as the cause and I haven't experienced the issue with any other ROM. The cash can be a nuissance depending on what you are doing at the time.
Cheers!

Battery Life
Im running FK23 leaked rooted with stock kernel. I use powersave mode that comes in stock settings app.
I don't limit cpu. I use phone to txt, play games, youtube, facebook, twitter, and instagram and google play store.
I get around 14+ hours usage.
Also, I try to use WIFI whenever I can. I turn off GPS when not needed. I dont use 4G often as 3G is pretty good on FK23.
Lasts me from 7:45AM to 10:27PM as of now on 1%.

Wow, and how much do you use you're phone throughout the day? I'm just looking for new ideas because I do several things to increase my battery length, but I find myself around 50% in the first 2-3 hours of my 11 hour day. :/

I bought a cheap ($10) extended battery and cover, and a cheap ($9) TPU case/ At 14 hours, I still had 61% battery left. I can get a full legitimate day out of it running 2.3's, but I am going to try JB and ICS again and see where it's at.

I run KingKang with the JB tweaks package. I also modified my build.prop for both performance and battery life. Plus I toggle my 3G on only when I need it. If I have a WiFi signal I'll do the same with that. I average 17 hours but sometimes I get more than 24. Inverted apps not only look great, but help with battery too.

I did the same as you until the fk23 leak came out. Calkulin's v3.0 gb is amazing for battery life, smoothness, and functionality. I was never fully satisfied with any of the ics solutions, stock or custom.
Although the fk23 battery life isnt as good as calkulin, I'm still using it as my daily driver bc it's jellybean and cool, the phone runs well and smooth, and battery is good enough for me.
To answer the op's question, I do the following to help extend my battery life:
1. Leave off all data unless I need to use it (3g, 4g, wifi).
2. Turn of autosync and only sync as needed.
3. Remove bloatware and/or freeze any unnecessary apps (use GSM battery and OS monitor to find battery hog apps).
4. Leave off GPS unless needed.
5. Set screen brightness lower.

Here's a link to my FK23 results over in the battery thread in General:
http://forum.xda-developers.com/showpost.php?p=34924972&postcount=534
I've only owned this phone since after the ICS update, so never tried any GB ROM.
The ICS ROM I've had the most success with is Re-Calked, but FK23 takes it just a step further for me. I know some people have been reporting issues with FK23, but for me it has been rock solid and has been my DD for nearly a week now.
Blu Kuban also did well with battery life, but it is a little over-customized for my liking. I also had some stability issues with BK. I used sleshpics M'ICS build for a while too ... again, over customized for my liking. Good performance and relatively stable. Also, I have never been able to get 4G speeds on any other ROM/kernel like I'm seeing now.
If I'm in an area with a strong cellular signal, I can get over 24h with 3h+ screen time both on and off WiFi. If the cell signal is week, I burn from 5-7%/h so maybe 15-16h if I was there all day ... but that would obv. improve if I threw it into airplane mode.
I have frozen all of the bloatware apps, don't have Google Now activated. Other than that, I allow syncing to occur per default. I don't have FB app installed.
I use auto-brightness most of the time, and I have a dark wallpaper.

dim screen. stay on wifi. that is all.

Honestly, getting use to a dimmed screen made a HUGE difference!!

Battery Life

Am I the only person who notices that all these battery save kernels aren't working for them. I flashed CM and I have been getting amazing battery life (13+ hours) with moderate usage, but with leankernel for example, I only get 9 hours max and my phone heats up a lot.

Not working for "them"? Or for you? Of course they do not work for everyone. They also may work well for one ROM but poorly on another.

No two phones work the same. I've had my S3 for about 2 weeks and have run Stock-rooted, and e few custom roms. I have 4 email accounts-pushed, 10 screen widgets, and always texting, web surfing, etc. I'm currently at 14 hours with 49% remaining. When I work in spreadsheets, and use a a reader, (usually 2 hours each) I still get 14-16 hours, no matter what rom/kernel I've been running

You just need to find the ROM and kernel combo that works well with your phone. I have tried ROMs/kernel combos that some get excellent battery life from but mine is horrible and vice versa. Keep testing as it is a trial and error type thing. Also your kernel settings can make huge differences. What works for one may not work well with your phone. Different settings on the same kernel may net you excellent results.

I guess I don't use my phone all day long, but on a TouchWIZ 4.1 ROM, the app "Battery Left" (from Play Store, its free) reports that I can get up to 46 hours on a full charge, based on my typical usage patterns (and if I use Greenify). On the other hand, I have used an AOSP 4.2.2 ROM in the past (such as LiquidSmooth), and Battery Left will tell me, after a few days, that I will get about 25 hours on a full charge (again, with Greenify). I have to do more testing, but there is definitely some difference between ROMs and battery life...

Guess mine is too...

I read this thread & thought battery life has as much to do with what's running in terms of synching, background data, services, connectivity etc.

I am using one of the unofficial CM11 ports that is supported nightly and have been getting terrible battery life. I hate to ask the question which is the "best", but what would be a good kernel to flash?
I do not do much heavy gaming either. In fact, I do not do any gaming. Just casual browsing.

Well before I suggest any kind of "good kernel to flash" I want to make note of something. If you're running a nightly of an unsupported version of CM11 then don't expect great battery life. This has little to do with what you're doing on the phone but the purpose of nightly's is to have users report bugs. Many of these bugs are the kind that can drain battery rather quickly. So the first thing I'd do is find a stable AOSP rom to run on before thinking about kernels.
That being said, a kernel universally accepted as "good" is KT747 by Koonsez

Thanks for the reply bud. I personally like supporting the nightly versions of ROMs but I wasn't thinking the reporting that I do is causing that much of a battery drain.
I may consider today to go to a stable AOSP ROM that isn't nightly.

I have been flashing ROMs now for the past 4 years. I have never really got into the nitty gritty of anything specific but probably best I do. One question I had in regards to all these ROMs is, do they not come with their own Kernel which I would have assumed is the best recommended for the given ROM. When i see battery life of 14+hrs with room to go, I must be doing something wrong.
Thank you for any info in advance.
