Das bamf and drods 1.8 bfs kernel set at 1.45. Usually get around 15ish hours with moderate use.

Fyretech rom with imoseyon kernel 1.92 dialed down to 1.792, setcpu, atk. Today is the first day running this combo phone has been on since 7am, moderate use (phone calls, texts, games, internet and youtube,) its 10pm now and i have 39% left on battery. I would have had to charge my phone at least once today when it was new out of the box.
EDIT: using 3g, 4g not available yet in central Jersey.

I'm using the bamf v4.3a kernel with the stock rom. i'm also using setcpu set for the 'ondemand' governor and a profile that underclocks the cpu to 245/245mhz when the screen is off.

BAMF 1.4 sense remix, with adrenaline (spelling? 4.4.2 kernel, dark horse theme, auto rotate Rosie (Saweeeet!) Optimal setcpu settings. Ie: charging profile (245 mhz min- 1.0ghz max/smartass) with this setting I normally get almost 1% battery charge increase a minute. screen off profile (700's mghz-1ghz/on demand. Screen on profile (1.1ghz-1.3ish ghz/smartass. etc... I know some stuff I mentioned doesn't really pertain to battery life, but this set up is just sick! Also, I read somewhere that its a good idea to let ur battery die completely, then turn phone on without charging (you may have to just a bit to get it back on) And let die again. This supposedly tells the phone where the dead zone is on the battery accurately, so it can now get a full clean battery charge. Myth? Idk, but damnit my battery is sick now! Hope this helps.

Personally, I've been testing Imoseyon [ROM] Tesla Coil Version 1.5, with Imoseyon [Kernel] leanKernel: minimal kernel "battsaver" .92 version. I am running it on "On Damand" with charging and screen off profiles, mobile data NOT on auto sync, Tasker for wireless ON at Home and audio OFF at nite.
Really, this seemed to have doubled my battery life. I was having to charge before the end of the work day with moderate use and now have been able to use well into the night.
Hope to see even more Rom/kernel concoctions out there as I love to try any new suggestions.

With adrenalines (I still don't memorize the spelling! Lol) 4.4.2 kernel it deff charges waaay faster as stated. Setcpu charging profile to lowest mghz min to around 1ghz max on smartass. Not demand, n it will bounce around to proper mghz levels as needed to speed up charging process. Its sweet n like you, I'm open for more suggestions

Adryn's debloat ROM and his kernel, with extremely light usage I pulled 38 hours (my previous record was 36). I have been using my phone for the bare minimum, so this is why I got so high. No, this is not real world usage and yes, I hated it, but it works. My normal battery life is somewhere closer to ~18 hours, except on Tuesday's and Thursday's, when I have lecture classes, I usually pull 9-10 hours, because I play games and browse the internet for 2 and a half hours.

Using imoseyon kernel 1.4 extreme(InteractiveX governor) with Tesla Coil 1.5. I have an extended battery, and with moderate use my phone can easily make it through one day into the next before needing to be charged.

Screen off and plugged in.. ;-)

I think it would be best to post in your stats whether or not you have 4g enabled as there are large populations of each way and it makes a significant difference.

What's the most noticeable of using with the extended battery? Extra cost, bulk or weight? Thanks.

True...4g always enabled for me other then when I get no 4g signal and then 3g may go into effect. If no signal at all, then wireless when I am indoors.
I refuse to turn off 4g as that is why I got the phone and my coverage is pretty good for 4g...so, better battery life is a must for me

leankernel v .6 @ 1.41 on demand with das bamf 1.4 remix and i disable data when not using it and right now im at 56% battery at 32 hours with moderate use

I'm using imoseyons extreme kernel on interactivex governer on stock. I'm getting 14hrs %40 battery with moderate usage. I'm mostly on wifi all day with a little of 3g use.

Huge *NOTE!*
Go to settings, menu, wireless networks, mobile networks and uncheck the third box. No need to have mobile data always on for most peeps . You'll still have 4G n everything, but gain a good 1-2 maybe more hrs (depending on use, kernels, governor settings, and I/O scheduling. I personally am running BAMF 1.6.2 with adryns 4.4.7 kernel, no set CPU, using tool box for that at 245mhz min - 1.02max with ondemand governor and most importantly SIO Scheduler. Try these n you will have amazing performance and better battery life. Let me know you opinions

Best Rom with Battery Life?

Hello,
What is your best Rom which have a good battery life?
Thanks!

you need to try yourself, because it depends on your kind of usage.
however, you can look around the forum, there are some very nice threads benchmarking the different roms/kernels/governors/etc...

For me it's nuhetri-reloaded + Air Kernel 3.4.5 using smartassV2+noop scheduler

This is my current set up (check signature). Its been the best so far with battery. I can leave my phone off for 6 hours and loose 1-2%. The performance is pretty damn good too, very smooth and quick
Nexus S (GSM i9020a)
AOKP (Build 27)
Air Kernel (3.45)
OC 800/100 (Lionheart)
Live OC 105

Seems like air kernal is quite popular atm.

if you want a Gingerbread ROM then do koush's ROM
http://forum.xda-developers.com/showthread.php?t=1091153
But if you want an ICS ROM then do SLIM ROM
http://forum.xda-developers.com/showthread.php?t=1495652
Just dont mess with the kernel.... I used the GB rom awhile and now this ICS rom... both get all day life and I use about 3 hours a day of surfing the web, about 2 hours of playing music and some games. Both have great idles that dont suck up battery life. Just be careful of some apps that drain batteries.... so try then bareboned then try with the apps you want. There will be a difference so play with the ROM to see what is best for you and ur usage.
Just use the notification bar to turn off internet, wifi and gps when not used.
good luck

I get pretty good battery life with vhgomez Lota r1 + Matr1x cfs 17.5. Averaging about 15-16 hours with medium use(about 2 1/2 hours screen on time).
Usually at 200/1000 with Deep Idle and either SavagedZen or Lulzactive.

I must say...BuglessBeast is treating me EXTREMELY well so far...I start my day at 4:00am, I don't usually plug in to recharge until around 10:30-11:00pm....
Very good lifespan... before custom ROM, I was recharge before dinner almost every day.
I'm VERY pleased with this ROM.

CM 10 performance settings

I just got upgraded from CM 9 stable to CM 10 stable and I love it. Only problem is battery life. I feel about a 10-15% reduction with the new upgrade. I've had CM 10 for about 4 days now. I don't want to touch the performance settings without knowing what I'm doing. Is there a way to change my performance settings to extend the battery life? Also has anybody played with a different kernel with CM 10 stable? Thanks

Don't worry about changing the cpu and governor settings. There is an option to set at boot. Make sure that is disabled, so if you have any problems a reboot will go back to default settings. I use the conservative governor, and have my minimum cpu speed set to 192. I've read that that speed is not entirely stable for many people, but seems to be working fine for me. That has been pretty good for battery life for me. I believe the default governor is interactive now, and the minimum cpu speed is set to 384 by default.

Do you just "feel" a battery difference, or do you have any actual numbers to back up that assertion? Keep a close eye on Settings / Battery and use Better Battery Stats to record solid numbers and identify what's actually eating your battery.

Also turn off google now location settings if ur not using it. They are really hard on the battery.

Disable Google now and battery should be back to normal here is some pics. Cm10 default kernel,stock clocks, no UV, on demand governed, and deadline as scheduler

Thanks for the replies.
It seems to be my screen that is responsible for eating up my battery. Have had the phone disconnected from the charger for 4 hours now and all I've done is 20 min with screen time doing a little bit of texting and facebook and my charge is at 75. I have the automatic brightness setting off and put my setting at pretty low.
The cell stand-by battery usage is 8% during these 4 hours. Should I maybe try another radio or is this normal? It lost signal for about 10 min today.
Just turned off google now and selected the conservative governor. Let's see if this makes a difference.
I used to be able to go all day with my phone with CM 9 and I even have the nexus battery.
Thank you for all your help

That's most definitely not normal, at least in my experience. Are you using the vanilla CM10 or some variant?
Some things to try:
Install Better Battery Stats (find the free version on XDA via a search) to see if any apps are causing wakelocks. This is a must.
Use CPU Spy or something similar to see if your phone is entering Deep Sleep. This is a must.
Turn off Google Now unless you actually use it
Turn off all unnecessary radios (WiFi, Bluetooth, GPS) unless you're actually using them
Turn off all auto-refresh settings in every app you have -- all social apps and weather are the biggies
For me, turning off the default auto-refresh in Facebook, Google+ and Twitter are massive savings alone, then Settings / Battery & BBS will help you locate the remainder of the headaches quite easily.
You might want to consider swapping kernels too, or at the very least reconsider your CPU governor and scheduler settings.

I would stay away from conservative governor you won't get much performance out of that, stick with what comes stock and use on demand.... even the default interactive sucks my battery down

I'm currently running the vanilla CM10
Turned off google now location access and set the govern to on demand early this morning and it is performing a little better most def.
I have noticed that my phone lost signal 4 times during the day for periods varying 5-10 min. I am currently on the I727UCLF6 radio. I'm thinking maybe I should try another one. Could that help with that battery maybe?
I have been thinking about switching kernels but I am a little doubtful because I don't want to mess up my phone too much since I so heavily depend on it. I loved the hotcakez kernel that came with AOCP, maybe i'll give it a shot this weekend.
Thanks for all the help people! Def the best forum by far on the web.

Just do a nandroid backup of the entire phone first before installing a new kernel and your risk drops to zero. If you install it and it all goes to hell, just boot back into recovery and restore your backup.
As for radio ... if you drop signal that often and your phone is constantly searching for one, I suppose that could impact the battery, sure. Are you certain you're in an area with solid coverage, though?
Learn more about the different governors and schedulers: http://forum.xda-developers.com/showthread.php?t=1950084

Yea I might have to play around with some kernels this weekend. Luckily it is a long weekend so I'll have some time if I mess up
My phone will go from 4 bars and a good signal at -78 dBM in my apartment and then randomly I'll lose signal for abut 5-10 minutes. A restart usually does the trick or I can just wait until it regains the signal which can be frustrating. I never had any problems with my signal at home running CM 10 so that leads me to think that there might be some problems with the radio.
Just want to confirm that these are the 5 radios I can use for AT&T even though I'm running JB.
http://forum.xda-developers.com/showthread.php?t=1754473

I've been using a UCLI3 modem I found on XDA a couple of weeks ago, it has been incredibly stable and strong for me. But as many people far wiser than me have said elsewhere, everyone's mileage with radios varies and it really just takes some testing to see what works best for you.

so I should be able to run the 5 ICS radios I found eventho im running jb right?
thanks for your help

[Q] Best CPU Governor for Battery Life?

Hi all,
I have been using the ONDEMAND CPU governor for quite a while on my SGS4G running CM9 (Team Acid's version, the final herring one), and I have just gotten used to the 12-14 hour battery life that I have had ever since I switched from GB back in August 2012. However, most of the frequent users here recommend the SMARTASSV2 governor, so I tried to use that yesterday to see if battery life was enhanced.
If anything it seems that my battery life got worse (see attached picture). I am a moderate phone user in general; I use my phone for texting mostly, and sometimes I'll look something up on the Internet, but no music, WiFi and GPS are always turned off, no overclocking/undervolting. I recently purchased a new battery as my old one died about two months ago.
I was wondering, is there any governor for the CM9 ROM that is particularly good with battery but doesn't completely drain performance?
(Also, I tried to use the LZ kernel before, but it seemed to cause many more problems than it fixed.)

You've got some pretty bad wakelocks going on there. See how your phone is awake even though your screen is off? That is an issue. Also how much screen on time did you have on that run? Get Better Battery Stats(free on XDA) then fully charge and look at what wakelocks are occurring. You might also want to consider UVing if you want better battery life.

Also, if you're a fan of ondemand, I highly suggest moving to ondemandX, which actually does deep sleep when the phone is off.
But that will only help if you fix the wakelocks first. So follow hechoen's advice and your phone should be way more awesome.

Downloaded BBS today, we'll see how it goes.

[Q] Battery Life?

Which radio are you gents getting good performance with decent battery life? I'm kicking around T989UVMC6 and it seems to be more power hungry but perhaps its just my area. I don't think this is very good battery life as I've barley used my phone today. I'm considering buying the battery for the nexus as it has a little more capacity and I've read it fits but I'm waiting on confirmation.
Anyways..I'm testing slimbean 3.1.0 build 3 with the T989UVMC6. I'm thinking of trying the LV kernel, what governor and I/O scheduler are providing good results for you guys?
And this battery: EB-L1D7IVZ

You running the standard JB one and not the GPU OC one? You seem to be playing with all the roms and kernels to..how would you compare it to LV kernel. Also, what radio are you using? Does it seem like my cell standby time is high in that screen shot? I have only made two phone calls and had the screen on a few times for a few minutes today. The phone was at 100% at the start of the morning and has been very idle so i'm surprised to see it so drained.

On page 5 on that thread is the link for X2. Flash X2 then the GPU OC Zip.. Using UVMC Radio. Haven't flashed LZ in a while so i don't know.

I'm using BlueLightning with Conservative and SIO, minimum frequency is 348 max is 1188. It's not the best combinauon if you prefer performance, I get about 18 or 19 hours of battery life I'm also using the same radio as you BTW .
