I've been running the 9/15 nightly, and while I haven't had excellent battery life, it has typically lasted around 8 hours or more. Today was a little different; with only an hour of screen time, my battery was down to 30%. On top of that, it usually takes 3 or 4 presses of the home button to wake my phone up.
EDIT: I forgot to add that my screen usage usually accounts for 60%, or more, of my battery usage--and that's with minimal usage. It always seemed like my screen was draining the battery even when it was off. It is much less now.
I read on the forums that a simple increase of the minimum frequency can resolve the waking issue. However, it didn't; instead, my battery life improved dramatically. I'm used to a pretty jagged and sharp battery graph, but now it's as smooth and linear as I have ever seen it.
Can anyone explain why raising the min freq improved my battery life?

Why don't you update? Its Oct 5th. Maybe give that a try? Old build man.
Well, I've considered it, but I always check the main thread first. It always seems like people are having LTE or GPS issues with the new build. Everything, aside from the battery life and screen waking, has been working exceptionally well. Not to mention, school and work hasn't given me enough free time to experiment with the new builds. I might try this tonight though.

The rom actually updates EVERY DAY you have missed many many updates here is a changelog http://changelog.bbqdroid.org/#d2att/cm10/1349329973
well all devices are not created equal. i suppose its possible that the ideal minimum frequency for your device is a above stock (or whatever you had it at before). raising the minimum frequency can improve cell connection, screen flickering issues, ect (things that cause battery drain).
also i advise you to update your cm build. either that or switch to cm monthly or another rom that doesn't push out critical updates every night. Try a rom that is considered stable like liquidsmooth, slimbean..
On the Oct 3 build and it's very fast. Batter life has been quite bad, have to charge it twice a day. Had a lot of crashing yesterday, phone decided to reboot continuously. Apollo has stopped error persisted until I cleared cache, and keep getting email/exchange devices have stopped errors until I disabled email.
Battery is the only thing that really bugs me though
Not sent from my toilet with a soap bar.
@nccu_eagles & @jefferson9: To be honest, I never realized the minimum frequency affected so many different elements outside of power saving. I admit I haven't kept it up-to-date; I'm always afraid to update after seeing some of the bugs people post. Perhaps I would be better off with a more stable release--at least until the semester is over, which will leave me with much more time to dabble. If I finish my homework in time, I might try a few different roms tonight.
@adammur: Those are the type of bugs that keep me from updating.
On another note, today's battery life has been great. My battery would normally drain between 12-20% an hour. Today, I'm averaging 5% an hour with similar usage. :good: Anyways, thank you guys for the replies. I'll see if I can't find something to better suit me.... for now :fingers-crossed:.
Before playing with the TouchWiz Jellybean Milestone 5 (Firefly) ROM by Drew Garen, I was running the JellyBro's euroskank October 3rd nightly along with LeanKernel as well as JuiceDefender Ultimate...
My Galaxy S3 could literally last 2 days with that setup. It was UNREAL.
The problem is, I really actually do like the TouchWiz interface (I know I know, I'm one of the few).
But if ultimate battery life is your goal with the Samsung Galaxy S3... Do a factory reset / cache wipe and install the Oct 3rd version of JellyBro's euroskank for the d2att... Then go ahead and install yourself the tmobile / AT&T version of leankernel...
You WILL NOT be sorry!

What did you increase it to, if you don't mind me asking?
I normally use up-to-the-moment builds (downloading 10/07 ad I write) and my battery life has been reasonable - up to two days total with light use. Seems to me to be a matter of making sure you're not running too many (any?) battery-hogging apps (BetterBatteryStats has been enormously helpful in this respect).
Unfortunately, I was unable to play with anything last night due to homework. I did, however, purchase and install BBS and JD. I'm actually at work right now, so I can't really post much other than a few screenshots.

You are not alone, I enjoy the functions/features of the OTA ROMs.
Notification accessible when in full screen apps, the multi-window screen lets you "clear all" and access task manager&Google Now, the stock dialer has more efficient functions(Displays all calls from a contact if selected, slide right/left to call/send sms)
But going back on topic, I set my cpu to be conservative but I'm not sure if that'll save battery.
I want to be able to game when at work but not have the power-saving setting limit it yet still be able to last me a day. The OTA ROMs' power-saving feature was able to do that.

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.

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.

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
This could be a normal thing but I've never really paid attention to my battery life until now. Since I have rooted and switched to different roms my battery life has been sub-par. Since using Desire-Z the life has improved, but still not as good as it was before I rooted.
Anyway, it says the display is taking up 89% of my usage which I find obsurd. I had the brightness set down to 30% so I don't see how it's possible. Could it be I have a very vibrant wallpaper set? Should I tone it down? The screen is set to turn off after a minute but when I'm done i typically lock it manually. Other than the wallpaper i don't see what I can do differently???
Is there some bug that I don't know of, is it just a false reading? Any advice/tips would be greatly appreciated.
go to ziggy471.com and try his latest nov kernel,14th I believe, and give it a try. after that try dl setcpu and just setup a profiles for when the screen is off to run under 600 mhz. thats what I do and get pretty good batt life. otherwise try some other kernels and see how they work out. another thing I actually don't know how much the display sucks from the battery but I keep my auto-bright off and display at like 10% maybe all the time

This seems to be the case with both the Desire Z and HD ROMs. I'm not exactly sure why but it happens to me and I saw a few other people talking about this.
I had a lot of trouble with this also... with stock battery I was lucky to get 8 hours out of the phone... I bounce between CM and MIUI and it seem the newest MIUI rom has greatly improved this issue... it did however introduce a new battery hog with the wireless drivers, but atleast that can be addressed with some tasker profiles or by manually turning it on and off. Im only 2 days into this rom and not quite ready to give someone a hug for the improvements yet, but i seems as though things are much better.
At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.
Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.
biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.

- use juicedefender and set it to aggressive mode.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.
I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.
Get a gnex extended....maybe a bad battery

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Yes exactly, I hate when people post screenshots of their phone getting 24+ hours, I'm there thinking "well obviously they don't use their phone alot". There is no way in hell i could get 24 hours no matter what rom/kernal I use. Im just happy when my phone can make it till I get home at night

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.
It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?
Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.
You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

i got a weird battery life yesterday, i was walking from work to home, i started watching videos on youtube, looked at the battery, 31%, after few videos looked again, still 31%, i walked 41 mins with a total of 9% of battery drain, i also played a game for about 25 mins, it was a really battery life.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.
This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?
Sent from my HTC One X using xda app-developers app
Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.
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?
Thank you.

I haven't been running ROMs for too long on my S3, but I'd have to say that AOKP by Task650 gave me the best battery life over some other ones I flashed.
Task560 ROM for sure.

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!

Task560 is just a little bit less than you.
I must say I'm running task650's AOKP build (I have been since I got the phone :good and my battery life has been nothing but immaculate. Here's a few screenies showing you my averages. Now mind you me my device and my daily operations will differ from everyone else's but still gotta give credit where credit is due. Oh btw I'm running it with tasks underwear kernel. Sorry ktoons

I think most of the roms have pretty good battery life. I'm on Vanilla Rootbox and i'm getting good battery life.
Thanks for all the input guys. Most of those mentioned were at the top of my list. Instead, I chose a "stable" Rom not mentioned here in this thread and it was buggy from the jump. I quickly bailed and went with CM10 and life is good so far.

DaRTHSTALKER is the first rom I've ever ran that I noticed a significant improvement in battery life. Very noticeable. None of the others have ever caught my attention before.

I'm on Slimbean 4.2.1 RC1 with lean kernel and I have to say it is buttery smooth and stable, fast as can be, and I'm almost two days into it with ~45% charge. Loving it
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...
Cheers

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
