Hey guys. I rooted my AT&T S3 recently, using the guide on GalaxyS3Root.com. However, I'm still rather unsatisfied... namely because the performance--especially battery and wifi performance--of this phone isn't that good.
So, I've done some research about ROMs, but I think the best way to do this would be to simply ask more experienced Android users about their advice. Two main questions (I'll bold them in case you don't care about my explanation):
Does anyone know a ROM that has a better "WIFI radio", and has lower power consumption than the stock? Well, no, the battery life part is mostly a no-brainer, I guess, since I'm pretty sure other ROMs do. The main thing is Wifi.
Particularly, the way the WIFI is so unreliable on my campus (GA Tech) is quite annoying. While my iPhone 3GS would seamlessly transitioning to closer wireless hubs in a building, this thing waits until the one that's like half the building away is fully out of range (it stopped being able to use the signal from it a long time ago). Someone on another forum mentioned that some ROMs may use a better WIFI radio ("the software controlling your 3G/WiFi receiver chip"). That's why I'm interested. Unfortunately I don't see any of the ROMs outright stating this information...
Battery life... well, honestly I should probably weed out more bloatware, but I have heard certain ROMs do this better. So before I go picking out weeds, I figured I would ask.
If the answer to the first question is yes, then does anyone have any guides to recommend for getting a ROM up and running easily (ie minimal hassle) and properly (ie nothing left to chance)?
Sorry if this is wall-of-text-ish, and thank you for your assistance.
WiFi is controlled by the kernel. Try anew kernel first
Sent from my A510 using Tapatalk 2
WiFi is kernel level. Try ktoonsez kernel, it has the newest WiFi drivers from Samsung. Also has tons of options to tweak your phone to optimize performance and battery life. Also if your on the stock ROM I recommend you flash a jellybean ROM immediately lol
Thanks for the replies, guys. Is installing a new kernel any more difficult than installing a ROM? Any recommended how-to's?
Also, for that ktoonsez kernel:
Will it work on my 4.0.4 phone? Also, the only thing I found was a code repository. Is there a precompiled version of that kernel? I mean, I've done plenty of C/C++ compiling here and there, but I still kinda don't wanna mess anything up and end up bricking my phone.
Thanks
Download from this thread. Make sure you download the right one (tw ICS)

If you don't have a recovery installed download ROM manager from the market and install cwm.
Then follow the directions in that thread. General kernel flashing procedure is flash kernel, wipe cache & dalvik, fix permissions.

Alright, I went ahead and did it. Installation went pretty smoothly (booting into CWM was the most trouble, just took a few tries..). The device is a bit warm right now, but it may be because I'm charging it. I hope this kernel doesn't eat my battery up more because of some random bugs. I do notice it has some clocking settings, though, which is really good. Namely, being able to set the maximum clock while the screen is off sounds like a pretty nifty power management thing.
Well, I'll be trying it out more over the next few hours.
Thanks a lot for your help.
Next issue:
As for improving battery life in general, does anyone have any app suggestions (app killers, bloatware to get rid of, etc). I already killed allshare (very happily I might add...). I think I saw a list somewhere on these forums, of bloatware it's safe to get rid of, but I'm not sure which particular apps have the most effect.

Kernel's have governors and I/O schedulers that you can tweak to get better battery life. As a start since you're on KT747, I suggest Ktoonservative and noop. You can look more into those on the KT thread.

I agree with this suggestion. The largest increase in battery life happened when I changed my governor to conservative and i/o scheduler to noop.

Hmmm.... well, that kernel didn't solve my wifi problem at all.
The battery life (when idle) went up by a tremendous amount, though, which is great. Android Kernel now hardly ever shows up in my battery monitoring app as one of the largest app drains, and that part is great. Opera seems to be a bit "heavy" on the battery lately, though... may just be Adfree.
I'm not actually sure what the wifi drivers solved. My wifi didn't really seem to perform too much different with them either way, and it certainly didn't improve the GS3's ability to keep a signal with multiple hubs around. I guess Apple is just that far ahead of Samsung when it comes to both their wifi drivers and their wifi hardware (which is sad, because I'm comparing a GS3 to a 3GS). Sigh. At least I'm graduating this semester anyway.
Does anyone have a different suggestion?
Again, thanks for all the help.
In the advanced wifi settings there is an option to ignore weak wifi signals you could try that although I havent had much luck with it, I have three wifi routers in my house to cover the whole house. Also see the below link to deal with tbe bloatware.

Exactly what problem are you having with WiFi? I believe once your phone connects to a router, it stays connected until you disable it or go out of range. I've never heard of any type of computer that keeps scanning for better signals. This would just waste battery life. There may be a 3rd party app out there to do this but I wouldn't be interested in that.
As far as improving reception, there's no software upgrade you can do to improve WiFi reception. I think the only benefit new drivers have is faster to establish connection time. Some cases (including my speck candy shell) ive noticed have interfered with signal strength slightly.

So you say, but that seems to be what my 3GS did, and the battery life on it wasn't bad at all. For instance, I could keep Skype on while talking to my friend throughout a large building with multiple wifi hotspots without hardly any interruptions (elevator aside.. well no sometimes it even worked in there)... and it had an Otterbox case on (a fairly bulky one). Heck, sometimes it even kept Pandora going while I was walking around campus, not even inside of any buildings, and pretty far away from the nearest wifi. On the other hand, the data speeds capped out a bit faster than the GS3... but that wasn't an issue since it was still well over 1-2MB/s.
Compare this to my GS3, which can't even keep Anime Radio playing within that same building. Hell, it can't even Pandora going... which is much more bandwidth-friendly and probably even caches a full song while playing it, so you don't get interruptions during outages. Don't even think about Skype.
I guess the GS3 just has a much weaker WIFI reception, both hardware and software. I think it could be improved if the software controlling it tried to at least immediately jump to another hotspot when the signal started getting too weak.

Yeah, I was just in a bit of a state of denial, I guess. I paid that much money for a "future tech device" that has worse wifi than something that was released well over a year ago. It's a little pathetic... exacerbated all the more by the fact that I'm still using that minimum data plan (~200MB/month) that I was using on my iPhone. I'm not trying to be an iPhone fanboy or anything. It's just that considering the evidence, this is just how it is. I might try getting it back to Best Buy since I'm still under there insurance, and try getting a new one to see if it has better WIFI reception, but it's difficult to do full testing without a control. I'd need to find someone else on campus that has an GS3 and then compare our signals.
Also, I am using a case. It's just an Otterbox Commuter.

It's worth a try. Where is this at? I can't find it.
That is interesting that you get much better performance on an old iPhone 3gs. Not really sure I've seen enough evidence to say the iPhone 3gs has better WiFi hardware than the gs3. Apple has been known to use top of the line hardware everywhere (that's why they're so expensive) so it wouldn't surprise me.
On a more productive note, why not use your mobile data?

Me and my mother have about 1 GB shared between us now, and that just happened recently. Until now, I was pretty much using a 200MB/month (or was it 250... whatever) plan, like I said in my last post. 200MB/month gets raped fast, even trying to use it minimally. Daily usage is pretty much impossible with that little per month. 200/30 is about 6.7 megs maximum per day. That's about 2 songs in Pandora.
I'd try flashing another ROM. Make a nandroid and try aokp, cm10, or slimbean. Its worth a try. I haven't been on the stock ROM since July and I've never had a problem with WiFi.
Advanced wifi settings are located here
Settings...press on wifi...capacitive menu button on phone....advanced. Should be in there.

CM6 is definitely great, I think without question it is a vast improvement.
The only issue I have is my battery life is ABSOLUTELY HORRIBLE. Could be the worst battery life I've had with any phone. But maybe that's just the EVO, with it's big screen and speedy processor. I underclock to 384 mhz sometimes but then the thing slows down and even freezes. I have 3 different batteries and they all perform about the same (not good.) Before I had a partial wake issue but that's gone, and battery life still stinks. I've also tried calibrating but nothing really seems to make it better.
I hear the snap thing is good for battery life but I everytime I open that thread I get a headache. I love this phone and am obsessed wtih it but that thread is a bit much even for me!
Can anyone give me a quick and dirty explaination of what snap is / how to use snap? Which kernel to flash? Some day I hope to digest that mammoth of a thread, but right now I'm too busy reading texts for college and Just want better battery life.
Thanks!
Download app System Panel. Will help show you what is eating up your battery/resources.
Then, download app Juice Defender. Worth it to get the paid version. Its like 3 bucks IIRC. This will help you get more battery life out of your phone.

Yeah, I tried System Panel but the things eating my battery were mostly system things, like Browser. I guess I could give it another go.
Why are Juice Defender reviews so bad? I've considered it before also, maybe will try playing with it again
snap 8.2 is the current release. you can try any of the kernels, but i would avoid the 7.0/7.1 SD Card implementations since that technology has been put on the back burner for a bit.
Snap allows you to you Overclock and Undervolt (aka: UV).
Overclocking of course is for speed and Undervolting may save battery.
all EVOs are not created equal. some like undervolting some do not. so snap is available in multiple flavors. each with a different UV floor. the lower the floor the more potential battery saving..but also the more chance for a random reboot or wifi/gps acting funny. remember UV retards the amount of power so things can act goofy. the different UV floors are 800mv - 925mv. for example...i use the 8.2_900 because it works well with my EVO. the 8.2_800 booted great but after a while started rebooting itself. 8.2_850 just hung at bootup. the 8.1 kernels didn't work for me at all. 7.3b1 was great.
HAVs is adaptive..so don't get stressed if your device fails to boot properly the first time. wipe the cache/dalvik and try again.
so download a few of the 8.2 kernels.
make your nandroid
begin trial and error (I'd suggest starting at 800, 850 then 900 to get a feel)
don't be afraid to wipe the Cache and Dalvik multiple times.
don't worry about the whole thread. just grab the last few pages and read the OP. then feel free to ask.
i also recommend setCPU. you can find some threads for SetCPU configurations to help. BUT....make sure SetCPU is disabled when flashing the new kernel. once you get a working kernel you can enable SetCPU...but during testing phase it will give you gray hair.
jmxp69 said:
Just a few quick thoughts on voltages/freqs after seeing a handful of discussion in the thread:
1) Every 8.2 kernel has voltages lower than stock. The default stock voltage @ 245 is something around 1050.
2) No real effort is made to UV at the top end. It's a little lower, but the objective at the highest CPU frequency is not to UV. Most of the benefit of UV comes at the low end of the scale when your phone is idle (most of the time). Less voltage = less draw.
3) nHAVS scales voltage at each step. There is a min.max voltage at every cpu frequency. This range is fairly small--50-75mv, but it enables HAVS to decide based on feedback from the CPU which one to apply. And the max at each step is lower than stock. So no matter how you slice it, even if you're running 925, you are undervolted. This becomes a question of how undervolted.
4) OC is not about undervolting, it's about overclocking. The differences is voltage vs. frequency. OC means we're increasing the CPU frequency beyond stock which is 998mhz in the case of Evo. If you move your SetCPU slider beyond 998mhz, you're overclocking.
The objective of overclocking is speed. The objective of undervolting is battery savings. Snap gives you both. We overclock when we increase the fequency with SetCPU. We undervolt automatically via nHAVS. As of this writing, UV is handled in the kernel, it happens most at the bottom end of the frequency scale.
I hope this helps clear up some of the questions. Great conversation by the way.

GREAT EXPLANATION Dragin!!!
and also, to the OP.... dont forget, if you do go with setcpu, do NOT 'set on boot' mmmmkay??? lol
Thank you Dragin!!!
That helps a lot! So once you have Snap setup at what you feel is "good" does your phone seem to perform as well as before you had it undervolted? Man, sounds like a pretty involved process - maybe I better wait until I can really sit down and play with it.

Do you mean for the first flash? Or every time you boot your phone?
If not set on boot, it means you have to start SetCPU manually after each boot. Doesn't seem right

Regarding Juice:
I didn't really read too much into the reviews for this particular app. It works. I was having battery issues. Downloaded Juice, got the settings somewhat right to my liking and so far no complaints. Unplugged my phone from charger this morning at roughly 9am, been using it moderately all day, and as of right now at 12:50am, I am at 29%.
Bad reviews or not, I can attest to it working and making a difference in battery life.

Correct.
You can set conditions to do certain things. Such as disable data/3g/wifi while screen is off. Also if you need data synced you can set a condition to enable data wifi or 3g for X minutes every X minutes/hours.
I am not affiliated with the dev in anyway but it def made a difference and was worth the price for it.

I absolutely adore CM6, but I'm really starting to think that it is not battery friendly. Last night my battery went from full to 25% in 8 hours. I had nothing running, my partial wake was fine, and Android system took up 60%+. I really don't feel like doing another wipe, but it looks like I may have to. Just want it to work right at this point.
Again, I truly love CM6, the open source concept, the transparency, the whole clean idea of it, but there is something seriously wrong with the battery life (at least in every install I have tried)

i agree with you. but i also feel that CM6 is on par with the Official HTC/Sprint ROM when it comes to battery life expectancy. however, after i put on the snap kernel and copied someones setcpu config....i got 26+hrs of 'use it as i wish' time + still had about an hour of in-pocket time left. i was hooked. i bet you an imaginary dollar the same will happen for you.
as for finding your EVOs kernel made in heaven...
it's not too bad so long as you have some time. but if you are time strapped, need your phone in 20min and don't read the OP... you will curse and swear. expect to get hung up at the HTC splashscreen a few times and it will bootloop on you before your done. <I'd suggest just leaving your battery cover off until you are done muckn about for that session>
klick may be easier for the some end users because of fewer selections. I've never used his kernels. if i try them, i'll prolly wait till he's put out a few AOSP versions...to work out any bugs.
oh yeah...one odd thing, it seems that sometimes folks flash a incompatible kernel it gets 'stuck'. after that 'bad flash' they are unable to flash any kernel until after they have nandroided back and rebooted...then they can flash again. i had this happen twice....i was unable to get a known good kernel to load until after i restored from backup. /shrug
oh....try this. download the snap7.5_925 kernel. if it runs smooth. call it a day and you should be pretty happy with that until the new versions come out. yeah, if you got one of the _800 kernels running you may pull an extra 30-45min of time...but that requires a level of geekdom that not everyone has.

Yeah dragin, don't hog those sweet settings! I'm enjoying Snap 7.6 and it seems to be helping out my battery life a bit, but I'd love to see your SetCPU details.
I've found that the issue for me is bluetooth. If I have it on constantly my battery will drain 10-15% per hour. With bluetooth off it's only draining 1%-2% per hour.
Seems like the bluetooth needs work on CM6 in order to have the efficiency that the other ROMs i've tried (Fresh and EViO) have. Nonetheless, I'm sticking with CM6 and just use the bluetooth when necessary.
I have the same issue with bluetooth on CM 6.0.0. I am running the stock kernel that comes with cyanogenmod, so this is definitely not a snap issue. There was a bug submitted about a month ago:
code.google.com/p/cyanogenmod/issues/detail?id=2136
I *really* hope this can get fixed for the 6.1 release, but it is currently listed with a low priority. I really love CM6, but basically making bluetooth unusable for more than a few hours really makes me struggle with the using this rom.
Why not the 7.6 with turbo...just wonderin
ever since I updated to 2.2, no matter what rom I'm using..performance has been so poor compared to 2.1. I wish I never updated. My battery runs out quick, temperature goes up to 100F even when idle and my phone hangs every time I turn on wifi. Hopefully I find out a solution soon, i've been flashing and uninstalling roms all day these past two days. I love the phone though don't get me wrong =\
That sounds quite odd.
Are you using an unmodified SBF, or are you using a release where the author/publisher has made a lot of changes? When having problems, it may be best to stick to one release and try to narrow down your problems, instead of trying many different releases and introducing new variables into the mix.
Are you overclocking your phone - perhaps it's causing the rise in temperature? Or are you running a lot of widgets? There may be some widgets that use the system too aggressively, causing too much strain/heat.
Hi! Did you do "wipe" before and after flashing?
That is very odd. I am on Froyo and performance has been phenomenal ever since the flash.
I agree with naenee, check the ROM you're flashing...
i flashed the UK 3.4.2-117 and right now using Pay's 2.1 rom. I remember that I did wipe data/cache before flashing and after flashing. IDK, im just not having problem's with this particular rom..it seems like it happens on all the other ones im trying. I get random freezes and especially when I toggle on wifi. I recently installed setVEL and will see if battery improves, this means i don't need milestone right? I'm also using setCPU.
I might try to flash 3.4.2_131-003 PL version. Will it cause any trouble and can I go back down to UK 3.4.2-117?
Seeing as it uses the same kernel, you should be able to do so...

No more hang ups or freezes but I still can't get the battery to last as long.My phone is mostly idled, running on 2G, just one widget, and everything in settings turned down to the least minimal settings..im talking about battery saver, screen brightness all the way down..everything off! 6 hours in and im already on 70%. I can live with that but I'm using setVsel and I know it could do better. Anyone know another way I can make my battery last longer?
I'm running Pays latest rom based on the UK 3.4.2 and it runs great. I'm also using setvsel (as every defy user should) and optimized all my vsels ([email protected], [email protected], [email protected]) using stability test. I haven't had a 'normal' day of use yet, but with heavy use (installing apps, web browsing, flashing rom) I've gotten at least a full day (~15 hrs) out of a charge.
I recommend minimizing your vsels using setvsel, then judging your battery life. Check out the setvsel thread for more help.

And remember this is a smart phone, some people report getting 2 to 3 days of use out of it. That's basically idle time tho. These new smart phones are just that, and use much more battery than the Dumbphone.

Even if that's the case (and I dispute it, I use my phone a fair amount in the ~3 days the battery averages), it still doesn't explain why the OP's phone is dropping 30% in 6 hours while idling.
When I updated to froyo, my battery life went from about 15 hours of use to 21 hours between charges. So I'm thinking the op has an app doing the draining.

Unfortunately, this is a characteristic of Android.... Ridiculously inconsistent in the battery department.
Wife's phone is on official froyo, has been amazing since updated (a few weeks ago) but since yesterday some weird reason it's been super glitchy and freezing up. Not sure why...haven't changed anything to it and she's only downloaded an app or two (such as pandora) in the last couple days...I was playing around with it trying to figure out what was up...can't figure it out. I went into titanium backup to freeze some apps thinking maybe some blur crap was freezing it up but TB froze up so I can't even get in there. Also, same as OP, the battery has been heating up really quick lately, especially when on wifi.
Not sure what's up here...but I'm hoping nothing serious! Will keep you all updated on this...we'll see if there is a trend going on here.

ever since I updated to 2.2, no matter what rom I'm using..performance has been so poor compared to 2.1. I wish I never updated. My battery runs out quick, temperature goes up to 100F even when idle and my phone hangs every time I turn on wifi. Hopefully I find out a solution soon, i've been flashing and uninstalling roms all day these past two days. I love the phone though don't get me wrong =\

check your cpu usage... if it's constantly arround 99%, you may experience the "usb-plug/unplug"-bug.
try enabling usb debug and restart your phone.

I would rather say it is a characteristic of people using android, to have widely different usage patterns, causing differences in how long a charge lasts for each.
Hi there. Have you tried to recalibrate the battery? There is an app on the marke called Battery Calibrator. From what I understand if you play with roms the battery can give you problems so it need to be calibrated again. I hope this can help.
For those interested... I'm having a problem, I don't know yet if it's a bug or a hardware defect.
My phones wastes A LOT of battery while it should be suspended.
I've tracked the problem to, apparently, Motorola's SIM driver. From what I've discovered so far, the SIM isn't accepting the suspend state and therefore the "suspend" process uses too much CPU time... all of this when the phone is, supposedly, saving battery.
As I can't get a motorola engineer involved, I can't say for sure if this is the true cause... but it's the closer I've got to a diagnostic, so far.
Your problem might or not be related to this, but if you're interested about what I've found or what my kernel log looks like so you can compare with your own problem... this is the thread at motorola's owner forum:

Aight so I downloaded juice defender free last night cause I've been having battery heat problems.....but it shuts off my 3g connection when the screen goes off and I can't seem to find the setting for it....I use Pandora radio so this is a bit of a *****.....any solutions?
Sent from my Incredible using XDA App
Thats pretty much the only thing Juice Defender free does that can save your battery, that and turning off wifi too. So if you disable it why even have Juice Defender installed? I too tried the free version for about 2 days and could never get my wifi or 3g to come back on so I uninstalled it and thanked god I hadn't paid $10 for the paid version. IMO its crap.
Juice defender is terrible. It kills your battery. well thats my experience...

Terrible app. If it does anything then it kills the battery... Brings android system to the top of the usage list, because it shuts off 3g and wifi..

Screen is still the top on my usage.
I have the paid version. It gives you the ability to lock items (like Pandora) "on" for data usage. Then, they don't get killed.
I had amazing battery life with it on my D1. Jury is still out on the Incredible. I'm still working through ROMs and Kernels.
I use it also. It has this new feature that you can tell it your local wireless and leave it alone. Problem is it doesn't work. Keeps shutting off my wireless when I'm using it! Very frustrating.
Also their developer is not very accessible. They want all issues solved through their forums. I hate that...The best software also has an accessible support system.
The one good thing I will say about it is it has the potential for taking over all aspects of managing your phone. A one stop shop. Just not there yet...
I used to use Juice Defender with 2.1 and found that it helped battery life. However, with Froyo, it just made the phone unstable. (It'd just sponaneously reboot sitting on my hip 2-3 times a day.) After uninstalling all is well.
A co-orker's Sprint phone had the same flakyness until he uninstalled JD.
Wild! I have never had random reboots. But, we all know how unique these devices are... even between the same model.
With warm twopointtwo, it doesn't seem to be turning on all the time... or warm is somehow killing it.
dbaps - are you still in 'training' for the wifi? It takes JD a couple of times to fully learn your location (based off of towers) and remember that as a wifi location. Check under the settings...it'll tell you what percentage of training it has completed.
Those of you who say its crap obviously dont have it configured correctly. I bought "ultimate juice" and when you go into the custom or aggressive profiles you can tweak everything until your heart's content! It still seems to shut off data when Im streaming stuff with slacker and connected to wifi, even though I tell it not to. Other than that it definitely will give you a few extra hours if you spend the time to configure it properly.
Terrible app!

There is no correct configuration to this app. That is why it is called "Custom". The reason it is CRAP is due to the reason you list as a problem among numerous other features that don't work.
Seriously, why have an option to automatically tweak CPU values if the option doesn't work with 99% of the kernels on the market, which also includes the STOCK kernel?
Yeah, it's a GREAT app!

True. For clarity's sake, I was using JD free so I don't know if any other version would have been better or worse. It's possible that the complex WiFi network at work (multiple APs per floor with a centralized controller) confused things.
My phone is a droid incredible, the co-worker's is a Sprint Epic. Different symptoms - he had phone lockups requiring battery removal to recover. Rooted, re-ROMed and still crashing until Juice Defender removed.
If you use Ultimate Juice and set up things correctly. This programs rocks.
It will turn on and off your data (3g and wifi) when you need it (according to the conditions you set).
It takes a little bit of reading and intuition, trial and error, and PATIENCE.
Use it for more than 1 day. Your phone usage varies day to day.
Again, read the text, THINK, and setup the conditions according to the way YOU need them.
I get at least 20-40% more battery depending on how I use my phone. I rarely charge mid-day any more and I can count on my phone having battery throughout the most useful hours of the day.
On light to moderate use, I get at least 14-18 hours. Just for fun, I once tested it and got about 29 hours before the battery hit 5%. That's with a little texting and a few phone calls. I use the stock, standard capacity battery as well.
SET IT UP RIGHT!
I've had no issues with JD running on 2.2.
Set on Aggressive. Only annoying thing is that I get the error notification icon for Weatherbug Elite every two hours because data is shut off.
First - I've got the most recent JD installed. The old one was kind of lame. People have made some good points, but there is a lot of incorrect information in this thread...
It works. If you are *NOT* actively using your phone, it will save your battery by disabling communication you don't need. I can go to bed at 80%, wake up 7 hours later at 79%, maybe 78% at the worst case.
If you are using your phone, it's quite nice - it comes on quickly - and manages my network well (at home, uses WiFi, elsewhere - 3G).
It's not $10.
My wife is using the free version and has had zero problems.
I've never tried aggressive, but maybe I will.
I cant comment on the CPU stuff - never used that.

I've never had a problem either. I'm running Skyraider 3.5 with incredikernal 2.6.32.27. I have the free version set on advanced. The best battery lift I've gotten with light phone use, texting, data syncing and browsing was 72 hours. Same use with stock rom and kernal my best was about 18 hours before I needed to charge. I know everyone is different, but that's my experience.

When I tried it back last Fall the paid version was indeed $10, its now down to $5. Which I still believe is way too much for this app. My 3g would not turn back on no mater what I did and yes I read the tutorials many times and had it set properly.

Perhaps for you. For me (stock ROM on my dinc) it made the phone unusable. Calling that observation "crap" or "lame" is convenient, but doesn't reflect the experience that I had (and which others had).
Again, with Android 2.1 JD did help a great deal. With 2.2, it didn't help battery life but made the phone crash. This was not a positive trade-off.
With froyo, I can go two days on my incredible between charges given light usage without it. Why put up with the instability just to get a few extra hours of battery life?
For example, I'm currently at 62% after 15 hours since unplugged with moderate usage of the phone, with WiFi and Bluetooth enabled. I could just turn off Bluetooth except when I'm in the car, but I doubt it'd buy me more than a few extra hours of useful life.
Juice defender has caused me multiple problems. Was the source of phantom call drops and sleep of death!! As soon ad I removed it, problems solved.

Also corrupted two SD cards, losing all my files, because of sleeps and reboot caused by JD. Does not play well with Z and HD roms at all. Works at first but soon became the cause of a lot of problems.

I dont use my phone a lot and my TWAS is usually 0%. I dont use my phone alot, but usually when 5-6 hrs of no use or very light use it has gone down around 20-30%. Anyone have any ideas of what rom would work best for me? I am on ICS 5.0 right now and it seems they are not coming back with their 5.5 they had out. I really only care about great battery life and having some type of hotspot hack or free tethering.
Thanks.
You have to try each one and see what works best for you. Read the ROM threads. Every phone and user is different.

I have been using the latest sleeper rom and i have left it at 1000mhz no overclocking and i seem to be getting better battery life than i was with some of the others. i flash frequently and i would agree with kennyglass in that each one works differently. so try for youself.
Well, like everyone else said, its depends on what your phones handles. Everyone phones handles a rom differently, well, not that differently, but enough to make big differences.
Like the guy above me, I also use SleeperRom. Its a very stable, battery efficient rom.
here is a list of roms I would try out...
ACS_ICS_V5.5
LegendaryRom
MarcusantROM
StarskyROM1.5
I also recommend CleanGB by toadlife. Fast, clean, stable, full day on original stock battery.

My wifes phone while at work would drain in 8 hours to the point that it was saying charge me every day. Now with Clean GB on hers it lasts about 2 days with light usage. Again YMMV.
Im on clean GB and getting great battery life. After 11 hrs of moderate use I still have 30 % battery left. After 8 hours of heavy use I'm at 30%. Very stable ROM.. No force closes or wierd issues.

I personally would towards 'which kernel should I use?' You've got to remember that although we all have epics, not every CPU is the same. What I am running it he or she is running may not be what you should be running. If you ever check out an oc/uv thread, you will see that people get different results using different settings, even though we're all on epics. You've got to try a couple different setups (roms AND kernels) to see which runs best for your device. Good luck!
via my EPICally transmogrified EI22: adrenaline injected & Supercharged
I currently use CleanGB which has been pretty great. If you're in an area with iffy service, that'll kill your phones battery pretty quick.
After installing a new rom make sure you charge it to 100%, wipe battery stats and then let it die without charging to get the most out of your battery (and having an accurate battery indicator)
In my opinion the way you configure your phone has by far the biggest effect on battery life, followed closely by the signal strength of the area you are in, with maybe a very small effect caused by the rom/kernel combination. Watch what you have syncing. Facebook and Twitter syncs can kill your battery, as can any other app that's always using data. Also, wifi uses WAY less battery than 3G or 4G. Use it when you can.
I'm on stock EI22 with mkasick's kernel and I usually get a full 16 hours with power to spare.

Basically Poit. Since no 2 people use their phone the same way it is retarded to ask for a comparison of best battery life. People need to stop being lazy and just try the ROMs out and compare for themselves based on their own use.

I agree. I have seen 3 questions over the last 2 days with these dumb questions.
but if I was to give my advice, I would strongly advise trying MarcusantROM, Battery life is pretty amazing, just be sure to flash a different kernel, as 2.0.6 is not even offered for download anymore because of bugs n such.
I would strongly advise the Shadow Kernel, paired up with MarcusantRom. You should see some pretty amazing battery life with that combo.
or try these out...
LegendaryROM
SleeperROM
Come on... "Dumb question"? "Lazy"? Get off your high horse. Certain ROMs give better battery performance than others because of certain tweaks and the OP asked for some general advice. Certain ROMs are certainly worse than others. OP wasn't asking for what would be best for him but what has worked good for others. Why is it so wrong for someone to ask for general advice about a ROM/Kernel combo. Not that hard of a question and not so ambiguous that it deserves a "dumb question" or "stop being lazy" response. If you don't want to help the OP, then simply DON'T RESPOND.
As for the question... I generally use the kernel that is included with the ROMs because normally that is what the developer has tested the most. I think Thunderhawk, Sleeper, and Legendary (in that order) are all good for battery but I haven't used all of the others.

In kind if you don't like the responses don't respond to them. I read for a month all the ROM threads before deciding on one to flash. Go to ANY ROM thread and someone there will claim they got the best battrery life there. It is different for every body and EVERY phone. ALL of the ROMs here have tweaks that work differently for everyone depending on use. Also people are sick of every other thread as "what's the best ROM". You HAVE to try them for yourself. If we are being to real for you then don't read what is written.
I was once where you are now. When I couldn't find a satisfactory answer, I made my own solution. I'll be uploading the latest version of it, version 3.3 today or tomorrow.
Battery Used: Extended Battery 2700 mah
Testing Performed: Idle Only
For those unsure, idle testing is simply when you treat your smartphone more like a phone. This included uses such as, checking the weather, responding to the occasional text, checking the time, etc. The primary goal of idle testing is to understand how long the phone can stay alive when used for texting and phone calls only. This is useful primarily for occasions such as, going on vacation, where you would like your phone to last a week or more in case of emergencies, but you'll be preoccupied and not killing your battery with Angry Birds. It's nice to know that our phone is capable older, simpler cellphones in standby time.
This indicates that my phone could stay on for as long as 10 to 14 days.
Direct arithmetic calculations indicate as much as 5.5 to 8 days on the stock 1500 mah battery.
Obviously, usage varies greatly between people and even between days, so anything other than idle testing is subjective. Testing was not performed on a stock installation, but rather, on my own daily personal fully-decked setup.
On the stock battery, I've played games for a total of more than 3 hours over a 48 hour time period before needing to recharge.
This has held true on my phone, my wife's, her mother's, and more than a thousand other user's phones. Yours may vary. Try them all. I do.
Looking forward to Random's latest!

Look no longer! Posted!
There is something going on with my phone, Samsung Galaxy S3, V4.3 where occasionally, lately it has been once a day the power draw from the battery will spike as high as 2,000ma (2 amps). This last long enough to drop the charge 10 - 20% and creates excessive battery heat. It happens on charge or off charge. I have tried viewing the running processes with System Tuner and nothing shows up in the list using an excessive amount of CPU. Better Battery Staus also doesn't pinpoint the problem. I have most everything Greenified accept Google stuff of course and useful stuff like email, etc. I now believe it could be connected with GPS since I turned off the GPS I have not had another event other than a 800ma spikes that quickly go away. Need more time to confirm it is GPS related. Are there any programs that will log which applications are using GPS? Any other ideas what could be the problem? I don't understand why System Tuner doesn't show me which process is eating the battery? Can anyone point me in the right direction.
I thonk it may be the radio itself. I have recently noticed similar issues on mine but its usually when streaming videos. I rarely use gps so i cant speak on that right now.
If i have it plugged in while doing this, it gets hot enough to trigger a shutdown due to thermal event....it crashes!

Same here, I also noticed with System Tuner that several applications that normally use 1% or less of CPU seem to spike to 8 - 30%. This all seem very odd. Now I am wondering if the background radio steals CPU cycles and leaves no time for normal applications. Anyway, the issues are reduced with GPS off although the battery does get warm sometimes without any reason I can fine. I'll try streaming audio and see if it triggers.
I would be willing to try a different radio. My current software is Model Number SGH-T999, Android version 4.3, BaseBand version T999UVUENC2, Kernel 3.0.31-1962493, Build number JSS15J.T999UVUENC2.
Unfortunately, no other radio will work. You can try one just to be sure about it. It wont brick, but just wont function. Youll have unknown imei and baseband until you flash the NC2 modem back.
Im currently running my port of S3Rx 4.0, but ill flash back to NC2 in a couple if days to test more on mine. Im also using a case/housing not meant for the T999 so theres a good chance that is contributing to my problems though.

Okay, thank you for the replies. Please stop by if you learn anything new. Velis Auto Brightness is up to 64% CPU usage, grrr. I posted on developers forum maybe troubleshooting that will lead to a fix. The 2 amp spikes haven't occurred since I disabled GPS, so I am guess you are correct about the radio.
The problem returned so turning off GPS isn't a complete fix, seems to reduce the frequency is all. It looks like Android System is the problem. If I shut down pull the battery reboot the bad behaviour continues, only fix seems to wait it out. My next phone most likely will not be a sammy.
Im not really sure what to suggest at this point. I can say that what we are experiencing isnt typical though.
Out of curiosity, have you given any of the ported kk roms a try? I think my Sprint port is probably the most stable/bug free, but they are all good and ive had pretty good battery on each one compared stock. (Ive always had good battery life even on stock though, aside from a few recent issues that I believe are more my own fault). TMS3KK is a solid rom with very few issues. S3Rx 4.0 is as well, but ill be posting an update to it hopefully later today, so I cant say its really been thoroughly vetted yet. Still worth a look though, imo.

No time to try a different ROM yet. I should have time the weekend after next. Thank you for all your suggestions.
I tried replacing the battery. After the first charge the phone lasted for 2 days before the battery dropped to 5%. It took 6 hours to charge back to 100%. No problems until later, it seems to dislike being unplugged moved to a new location and plugged in again. This appears to be when the problem occurs. I usually just leave the phone plugged in all the time. I'll test further with the power before I make up my mind. I think this will be the last Sammy phone for me?
Is it a non stock battery? I've always had issues with those reporting correctly.

Usually I would buy a non stock battery however since this phone lays next to me in bed to wake me in the mornings I am a little concerned with a fire so it is a Samsung battery from Samsung. Leaving it unplugged for a bit and plugging it back in didn't work stop the battery drain. There are no processes eating the battery according to System Tuner so got to change the ROM.
Should I try a ROM first or kernel or both? Could it be an Xposed module, thinking about turning all of those hacks off?
I just remembered, this only happens if the screen is on and the phone is plugged into the charger. And rebooting doesn't clear the problem.
I would start with a stock based ROM. If it were me I'd go full stock rooted. But yeah I'd ditch xposed for now. You might even try reflashing your current ROM, factory resetting and this time don't use any exposed mods. If it still has problems, then try a different ROM.
It wouldn't surprise me at all to find xposed was the culprit. Its really cool, and the dev is amazing, but I prefer not to use it at all. IMO, it's much better to have the mods coded into the ROM itself.

Thank you Doc, will do so and report back here the results.
My phone does the same thing now. My phone never did this when I first got it a couple years ago. I use GPS a lot because son plays on a travel hockey team. I could drive 3 - 4 hours away with the phone on and plugged in using the GPS without any issues. Now, my phone gets so hot in about an hour of the same type of use and it shuts down.
I thought that maybe there was something wrong with the phone because of age but now I see it could be something different.
It very well could be age related, or it could be partially due to that too. But I'd do as I suggested above and run stock for a bit to test. If on a custom rom, and especially kernel, you could run into issues like that too.
If you have the same problem on stock, (and you're sure its not an app acting up), there's a very good possibility that its more of a hardware related issue.

And it is not the battery. I can't load stock until next weekend, need my phone for work.
You can always use better battery stats to investigate while you use it normally. Let it log all wakelocks, including kernel wakelocks for a full cycle.

Tried that, been there, odd thing is nothing shows there. I'm gonna reload with stock per your suggestion next weekend and if that doesn't work I'll try a custom kernel.
Try remove greenify app and see what happens. Cuz with my case the latest version (2.4.x.x) of greenify driving my phone nuts. That app used to be great.
I'm back. Loaded stock 4.3 ROM / kernel, radio is at newest versions, I am going to say the problem is gone. The battery heats up to about 32-33 degrees Celsius however the phone isn't hot like it is burning up so I believe the problem is like Doc suggested earlier with the radio. Which would explain why the process monitors never see any rouge application using to much CPU. So after some pondering, this doesn't stop a rouge application from using to much bandwidth and cooking the radio so to type. If I had to pin it down I am going to suggest it maybe one of these two applications: FCC speedtest and or Opensignal or some other application. Both of the listed applications periodically test the network bandwidth and report back to a central server. I suspect that this maybe trigger the heat problem from the extend radio usage. No proof at this time just conjecture.
I am considering jumping to an AOSP ROM to be free of the Samsung bloat, NOT CM, don't care for CM, does anyone have any good suggestions to try?
