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.
Running for 22h 4min
Screen on low: 39%
OS: 15%
Phone inactive: 12%
Voicecall: 9%
Mobile rest: 6%
Android system: 6%
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 based on kernels and ROM combinations

Been playing with many combinations of ROM and kernel yet seems no matter what I try battery life is poor. Right now running coreDroid 1.3.3 with latest Franco kernel seems so so with slight under voltage settings within setcpu. So what is everyone else opinions? Thanks for feedback!

My best combination has come from AOKP Milestone 3 and Faux's 12u kernel. Usually get 16-20 hours with light/mod usage during the day and heavy usage in the evenings.

Best battery life I've seen yet is the stock 4.0.4 release w/ the kernel that comes with it. I get 4-7 hours with mod-heavy usage and 14-16 hours of light-mod usage.

I get 2-3 hours using Franco's kernel. Really not great. I should look around for a better kernel to suit my usage.

Jeez you use your phone a lot. I'm on kang 1/31 with faux's kernel. I use my phone for the commute to work and turn off lte when I get there. Mostly music and reading. I have it underclocked at 1060mhz and running under performance governor, it helps me check my phone and send out texts at work faster. Then at night I flip on lte again and a lot of the times go out. I don't think 15 hrs is too bad.

best battery life i had was 36 hours with moderate usage. no lie.
aokp b17 + francos 13.1, smooth and amaziiiiiing battery life. if i wasn't a flash junkie, i would be sitting on that right now.

I'm a little confused by your post. Are you developing a kernel or a rom? Either way looking forward to the release.

I mean screen on time!
I got 42 hours without charging the phone yesterday, with 2 hours 40 minutes screen on time. I was using it very sparingly over the period though.

If we you want this thread to be useful we need to make sure all posts at least state screen ON time. Even then there are so many other factors:
Screen On Time
Total Up Time
GSM/LTE
ROM
Kernel
Kernel Freq
Kernel Governor
Screen Brightness (Avg)
WIFI state
BT State
etc
Okay so I'll start...
Screen On Time - 3-4hrs
Total Up Time - 14 to 25hrs
GSM/LTE - GSM
ROM - AOKP 22
Kernel - Franco 16.2
Kernel Freq - 700/1000
Kernel Governor - Turtle
Screen Brightness (Avg) - <40%
WIFI state - On
BT State - Off

Clarify Battery Life Info
I am not developing anything. I am just wondering what people that flash different kernels and roms have experienced and settled on as far as best battery life. In my sig there is the one I currently use. I actually have been trying franco kernel lately and that seems to be slightly better. Its tough to tell since I try to plug in the phone as often as possible either to outlet or my laptop. Does that help clarify what I am curious about??

ics and battery life

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.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

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.

Duel core vs single core

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.

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.

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.

[VZW] Galaxy Nexus - Battery Life suggestions

I have a VZW Galaxy Nexus and I am trying to improve the battery life on the device. I really don't do much with it other then texting and some FB/email here and there during the day. When I am driving back and forth to work I use the device to stream my music or run Pandora.
The battery life during the drive is not the huge issue, I know that using LTE and streaming data is going to use battery quite a bit, but when my phone is still with Wifi off at the office and I may send like 5 texts the device can drop 20% in 10% in an hour.
I am using Winner00 - CM10 rom right now with the kernel. I am about to try AOKP Build 3 but wanted to get any idea of what others were using and their battery life results. I am running the stock battery in the device.
Battery life and Stability is the most important things to me. Running the phone at stock GPU and CPU speeds is fine for everything I do.

There are some things you can do to improve but nothing that's really going to be a game changer. Buy a few extra chargers. There are a plethora of battery threads already, use the search function.

Get a giant 3800 battery like I did. It's ugly but I get over 5 hours screen on time and a day of use

You should give lean kernel a try. I'm a heavy user on aokp b3 and always on 4g. Since using that setup I've seen improved battery. Every kernel is different but lean kernel seems to have consistent performance.

Dude, get AOKP build 3. It is really good with battery life and also, it is extremely smooth. Although, I do recommend using Franco's Kernel in combination with this ROM to get maximum satisfaction. I get around 3 hours of screen time, with 4G and WiFi in there. And also I have stock battery. Now thats saying something.
