Rom with best battery life

Alright guys, whats your opinion: which rom has the best battery life?
Sent from my Galaxy Nexus using xda premium

AOKP + Latest Franco Kernel

Thanks. So far I've had my best with eagles blood and stock kernel. I've heard Franco's kernel has bad battery life though?

Sounds like an easy thing for you to test, doesn't it? Sorry to be snippy, but this is one of many similar threads. No one searches anymore, and there are many threads like this which have "it depends" as the only logical answer.

I have been using Francos kernel, and the new baseband, with both KANG and eaglyblood, i hav ejuicedfender installed on aggrasive, but i still cant get out much from the phone, i have right now on eaglybloods latest 1.5.

Mediaserver: 4%
Now i havent used it alot, turn of everything i can, when screen of running on 2g only and such, i havent used it alot, listen to music for totaly 1h 30m. No surfing and such.
What roms and kernels have you used and what have you gotten out of it?
What extra apps maybe taskkillers and such do you use or think is good to get more battery?

Bad battery life? Do some searching and read his kernel thread. Battery life has been amazing with his past releases. Build 7.1 are heavily exceptional builds.
Anything before that, yes the battery life hasn't been so good. But now his focus shifted onto the battery. Many people included screenshots of their battery graph.
Aokp also has a power saver mode, read into that as well

I did run AOKP build 12 for 1 day, and thats how long my battry lastet with nearly no usage at all. The same with eaglyblood all on latest fran kernel, with juicedefender ultimate on agressive setting.
So how can i test and post graphs for you?
What baseband are you on?
Is there any good taskiller i can use?
Dont know what is using so much battery except the screen and i have it on very low always.

I use stock 4.0.2, non rooted or unlocked bootoader, and I find the battery life better than most android phones i've used previously. However, occasionally, it gets low, then i plug it in, and later it's charged again!! As if by magic!! Also i noticed that if i turn it off completely, the battery life is aammmmaaaazzziinnngggg!!! *palms face*
sorry, these battery life threads really get my goat! On a serious note though, one nugget of knowedge that I have taken from messing with android for years is, that if you, like me in the past, have been one of these types that just cannot stop flashing roms left and right, then you will never get to see the full potential of your battery. It does depend of course more on individual usage than anything else, but, settling on a rom of choice and using it normally over the course of a week or so will see you gain an increase in capacity thereafter, just through simple calibration.

Im running AOKP v.13 with Franco's Kernel 9.2 and battery is really great, even on heavy usage. There's almost no batter drain in Sleep Mode (last night ~8 hours, the battery just dropped for 2%).
I've set up my syncs, set up AOKP's Powersave Mode to my wishes and made a ScreenOff Profile for franco's Kernel. That's all, and im still on my second battery loading cycle. Cant wait to see what will happen if it's callibrated well.
With AOKP Rom and its Powersave Mode, you dont even need Juice Defender anymore, its doing nearly the same.

Thank you, i will go back to AOKP in a few days and try build 13, i update you all
My battery holds 1 day 24hours, would say normal use with 2g on when screen of, 3g when screen on, i dont surf on it check facebook maybe 2 times on it, nothing more, text sms and few calls lasting maybe 40min total

How is your standby drain with that setup? 1% per hour? Or less?

Battery life with Jellybean

I know it's still early but has anyone else found Jellybean to have worse battery life compared to ICS? I'm totally stock with only the bootloader unlocked. Usually after a full day use with ICS I have 30% left and with JB I'm around 15%. On a day with heavy use I'm sure I will have to charge in the middle of the day which is very inconvenient. I'm trying to see if it's JB itself or some app which is draining things now that I'm on JB.

I'm finding it to be significantly better actually. I couldn't make it through a full day on ICS most days. With JB i'm easily above 30% most days at end of the day.

Maybe its because you like more your phone now and therefore you spend more time playing with it

Do you have Google Now enabled? The frequent location pings and GPS wakelocks drain the battery

Mine seems worse compared to 4.0, phone doesn't go to deep sleep and keeps waking up ... maybe it's my Exchange email account, but this was fine when I was on 4.0.
How is your phone sleeping?

This may seem a strange suggestion, but I've found that leaving wi-fi on, even when I'm not using a wi-fi network seems to even out the battery drain. Helps to get Google Now working 100% as well. So try that when you can. I've found it works fantastically for me.

Stock vs. stock ROMs (both using LeanKernel as well) I've found Jellybean to actually have better battery life. I managed four hours of screen on time with the stock battery yesterday and today, something I could never come close to accomplishing with stock ICS.

turn off wifi, gps and 3g, and you'll go far. Turn em on only when necessary. I leave google now on. I'm only at 40% after 22 hours. Granted it defeats the purpose of a smartphone, but if I'm at work, working...then I don't need all those things turned on.

Turn off Google now of you don't really use it. I loved playing with it for a few days and realized it wasn't THAT useful for me I only really used weather. I keep the voice search active and turned the cards off. I just use a decent weather widget and maps WHEN I'm travelling if worried about time. HUGE battery saving. So many (understandable) wakelocks when activated.

It's weird, it seems the battery life is worse, but it could be that I'm using it more than before. The on-screen time does seems slightly better than on ICS, but I'm going to need more testing before I can confirm...

Hmmm...I will try that out, thanks. Google now was fun to play with the first couple days but if it means I need to charge middle of the day forget it. I will try turning it off and see what kind of results I get.
For the record, I've left all my GPS, Wifi and sleep settings intact from ICS so those settings shouldn't have effected my battery life.

I don't care for Google Now, just the new voice search part.

I'm actually getting better battery life on Jelly Bean than I was on Ice Cream Sandwich. Running at a higher clock isn't the only thing (or the main thing, I think) that gives Jelly Bean it's buttery smoothness.
Google really put effort into improving Vsync on the device, which mainly gives the device that buttery feel.

Battery drain on clean Rom installs.

The last few nights, I have tried a few different JB Roms. All with the same results. My GNex has a full charge before I go to bed, I wake to my phone telling me to charge it 8 hours later. With NO wifi or network data on. This can't be normal.
The roms:
ASCENT 3.0
Jelly Belly 4.0
New Unofficial Cyanogen Release.
No extra apps installed. Purely stock.
Tonight, I'll try it in airplane mode, and see if my network coverage is what's draining the battery. But for the most part I'm never without a signal.
Any ideas or ways I can see if the battery is just bad?
Also, what would the current Verizon radios be? I believe mine are up to date, but I guess that could be an issue if it is indeed my network signal being dropped.

Im on the 07/27 fitsugly cm10 rom with r225 franco kernel and for some reason my battery life has gone through the roof, after 30 hours of being on the battery is still at 56%. Granted im not using it much now but still i've never seen this type of battery life before. Overnight the battery dropped maybe 4% at best, wifi is always on and its fetching emails.

How odd have you tried charging up and resetting the battery stats ? May help

I installed the newest version of the ROM. I was curios what the different GPU kernels were for. Is there one that Toro should use rather than the other? I think I installed the 512 version. Should I not have?

Minooch + franco.Kernel #223 (see attached files). I haven't used my phone much in past 24 hours, but battery life is awesome. I use latest bootloader and radio firmware, CPU is set on interactive governor, 1420-384MHz, max screen off CPU frequancy - 729MHz, 512MHz on GPU.

I think I tried that ROM before, not sure if its just for maguro. I have a Verizon toro.

If you don't need the higher clocked gpu speeds then just stick with the 384mhz kernel.

Try better battery stats... I am on gsm nexus.
I tried jelly belly, minco , paranoid android, and xenonHD plus bigxies stock. I've used Francisco Francos kernel on bigxies and that gave good battery life but the others all burned cpu and battery, specifically via Android.mediascanningservice. and maps.
Right now I am back to stock 4.1.1 rooted courtesy of rom toolkit and with better battery stats and cpu spy I have a cool phone.
One thing you should be aware of is if you have a lot of media on your phone the scanning service can take a long time to run and calm down. I I upgraded my bosses razr to ICS and his phone took all night to update I guess he has lots of music on it...
To increase battery life you can install titanium backup and freeze maps, and wallet when I not in use. You can install rescan media from the app store and trunk off media scanning service. Or just buy a bigger battery.
This is not a knock on the custom roms. The rom teams mentioned above they are all awesome and are the reason us crackflashers have so much fun. I have learned lots from this experience and have a better grasp on how my phone works due to the efforts of these devs. For now I am sticking with stock... I'm sure I'll be flashing again soon.

You can never judge a ROM on battery life within a day. Every ROM I flash gets bad battery on the first cycle and most the time even the second cycle. You really have to stick with a ROM/kernel combination for at least a few days to be able to judge battery life. It may just be a placebo effect but I use a battery calibration app each time I flash

Resetting battery stats accomplishes nothing related to battery life or reported percentage. It's been debunked some time back by Google.

Best ROM for Battery and Data Use?

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

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

stock is always best.

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

Every bodies phone acts different with certain ROM and kernel combinations I have had good luck with lean kernel but that doesn't neccassarily mean you will
Sent from my Galaxy Nexus using Xparent ICS Tapatalk 2

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

I've got my first android device just a bit longer than a week ago so I haven't had the chance to test a lot of ROM+kernel setups.

[Q] What ROM do you think is the best on battery life?

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

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!

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.

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
