I've had Franco and Modaco 4.0.4 installed on my GSM Nexus for about a week so far and battery life is actually worse than it was on stock. Even with the phone underclocked to 1Ghz. Which roms/kernel do you guys recommend for the best battery performance?

I'm running a stock ROM, stock Kernel, the only thing I've changed is the Radio. Running the Docomo LA1 one that is floating about and I'm getting 24 to 36 hours before I need to charge it. However there is still a radio draining issue with 4.0.2 but the LA1 radio reduces this drastically.
Also make sure you update Google Maps to the new version if you have it installed.
i'm using ARHD 2.1.5 rom + James Bond 1.4Ghz OC.....battery seem good....after 8 hours, battery drain about 19%...i just follow undervolt he gave...AOKP Kang also seem good to...
Just so you guys know, I used to get 3 hours of on screen time on stock. Now I get 2.5 while underclocked and undervolted. Screen time is the best way to judge battery life.

I use morfics kernel and bigxie apex. 5 hours of screen with the extended. You shouldn't have to worry about getting less than 3 with the normal as its barely bigger than stock. I would check out what apps you are using as well. Seems the more I install the worse the battery life gets, especially stuff that pushes in the background.
Also I would recommend not undervolting. My phone doesn't tolerate the 1500mhz kernels or being changed from stock too much. I've noticed when I UV too much or oc passed 1350mhz the phone seems to go into limp mode, gets slower, hotter, and reboots more. I think all of this kills battery life.
One last thing, if you are on T-Mobile, try the ugkl1 radio. Not sure whether it does anything for att but the improved signal and less drop helps battery a lot. Hope that helps.

That doesn't sound better than my all-stock 4.0.2.
I've always wondered this about custom roms; how can a few people working on roms in their spare time make a better product than google with all of their their paid engineers/programers working full time on android?

Ive got AOKP #23 with Franco and I'm easily getting through a day with moderate use.
Though gaming is really hastening the interval between each charge
I'm running AOKP b23 and the latest (?) franco.Kernel. Battery life sucks (10h max of battery life with light use - the occasional web surfing for around 5 minutes, screen on for a total of about 1h30min). Now, I carry a battery around in my pockets... sigh

the extra battery that u carry around, is it original? if not, where did u buy it from and how's the performance compared to stock?
I am running the combo in my signature and getting actually pretty good battery life. ROM and kernel are not everything. Let's not forget that usage is important.

They don't. The mods add new features at the cost of compatibility/stability/performance. These are often mutually exclusive.
I've been running my custom Linux kernel for as long as I can remember just out of habit (and to remove unwanted features as well). But I wouldn't touch any mod for some theoretical performance/battery life improvements for fear of the phone dying in an emergency.
(Dog-fooding my custom ROM that is very close to stock).
Does no one use Glados kernel ? I seem to get the best battery life by far with it. No over clock just stock settings with AOKP.

Yeah, I have to say Franco really disappointed me this time I'm running on AOKP build 25 with franco's latest kernel and quite honestly, the battery life is horrible. 6 hours and im at 39% with only 1 hour screen on time. I'm also looking for alternatives.
EDIT: As mentioned by the post above, the Glados kernel is really amazing and if you guys can, you should give it a try.

I have used Glados for awhile. I compared the overnight standby batt drain with Lean and Franco kernel and Franco is the best, though by 1% only, so by and large I'd say they are mostly the same.
The main feature of Glados is the Wheatley governor but I don't really see much difference in terms of stats in CPU Spy as compared to the rest. My Deep Sleep percentages are still almost similar.

I am looking for a rom with good battery life, I just got the phone and I love it, but it should have a bigger battery! My Cliq XT had a biiger battery, at 1390 mA lol. I have tried CM7-RC1 and now I'm on CM7 Nightly (released on the 25th). Currently downloading Virtuous and will give that a shot.
Stock ROM. Period.
I have been unsuccessful in finding a ROM that can match the crazy battery life that I got on stock.
I used to get 30+ hours on stock. Now, I can't get more than 10 for sure..
I keep jumping from ROM to ROM, maybe that could be an issue too with battery stats in CWM and stuff... but as far as I'm concerned, stock is the best option for the best battery life.

I noticed No difference with stock over any cm rom i have used. Battery sucks. Htc overall sucks with battery life. For some reason any htc device i ever had sucks balls. My mt4g was probably the only good phone in terms of battery.
Otherwise htc is retarded.... 1200mah is plain dumb on a smartphone.
From my permarooted 1209mhz G2 with CM7 nightly 6
Different people have different results. You're gonna see someone with every rom in the dev section claiming ridiculous battery life. When it comes down to it you have to realize everyone uses their phone different and the rom isn't gonna make the biggest difference, its how u configure and use it.
No matter the rom, using things like SetCPU, juicedefender, etc. and other battery savers can improve ur battery life. Most dev roms are going to offer better performance and life, just choose one you like and set it up the way u like it. The only way to know what to rom offers the best life for u is trying several and comparing.

No. I'm not kidding. Rooted via the non-ADB method. Flashed CM6.1.1 and didn't mess about with any different kernels or radios.
However, when I try CM7, my battery life is halved. Maybe I got lucky. Best battery life I've ever had on a smartphone. Not even my old Dash lasted this well.

Its because hes hardly using his phone... If you have a screen off profile and let your phone sit for long extents of time you can easily get that kinda life. Don't expect it when you actually use it regularly or keep the screen on for any length of time. See these are the people I'm talking about. You're always gonna find someone running every ROM out there that say he/she gets great battery life on it.
I personally am on CM7 overclocked to 1ghz and im at 43% battery with 12h 34m of usage today. General usage off and on, texting all day and some phone calls/app usage etc. The problem is I can easily have days where I only get 12h out of the whole battery because I'm on the phone all day doing things.
Even something as small as signal strength where you use your phone can effect your battery life numbers. take every battery life screenshot with a large grain of salt. The best thing about the battery meter in 2.3 is that it at least shows how long the screen has been off so you can tell when people just idle their phones to claim huge battery life numbers.
That is one of the things I really liked about CM7. The battery graph.
Never said I was a heavy user. I quantified my average use by time and activity. Still, with the same average use, my battery life on CM6 far outstrips CM7. They're both excellent roms. I like many of the new features in CM7. However, the battery life and GPS troubles influence me to continue using CM6 as my daily driver.
Once I figure out how to replicate the battery life or CM7 hits stable, I'll gladly upgrade.
Try out some CM7 nightlies.
I'm on nightly 12 and I get excellent battery life: as much or even better than stock. GPS also works without a hitch. I remember my first lock took like 20s max. And navigated without a data connection using Navigate (voice guided) for 45 minutes without a hitch. After that may bat was at about 79% I ended up not charging until 15 hours later.
So yes, Nightly 12, atleast for me, is solid. And I will never upgrade until something better comes along.. like the Meizu rom.. your mileage will vary though.

Sent from my CM 7 Monster Evol.
I had the Thunderbolt with OEM extended battery, AOSP rom (TH3ORY roms), and imoseyon's lean kernel and used to get over 24-30 hours of battery life.
I've tried the 4.0.2, 4.0.3, and 4.0.4 with imoseyon and franco's kernels and still 7-8hrs is all I could hope for my Galaxy Nexus(stock battery). I've ordered the bigger battery with Costco but not here yet. Any suggestions other than the obvious: (please add to the list and I will update this original post)
1- Keep on AUTO brightness
2- avoid widgets
3- use a custom kernel (which one?)
I use francos with CM9. I always have everything switched on (Data, Sync, Wifi, GPS) and it only goes to about 50-40% after a days use and I consider myself a heavy user.
Edit:
As for using an extended battery, am I right in thinking that its only a 10-15% increase in capacity?

I have not had the extended battery yet, I will let you know when I get it. Do you change anything in Francos's kernel? I had a terrible experience. Isn't CM9 just a nightly release? Stable?
What radio are you using? I'm on the 4.04 radio
Hi guys, new here. I'm on the same boat as you on the battery, I'm running AOKP25 with Franco Kernel 18... I run a Hyperion 2000mAh battery and get about 8 hours with normal use , WiFi on, GPS off, Screen Brightnes on Auto, some whatsapp, emails, a couple of calls, a bit of browsing, and about an hour worth of reading in the kindle app... I know this should last longer... any ideas?
I can't post pic of the battery usage because I'm new but it basically is:
Screen: 57%
Android OS: 26%
Voice Calls: 4%
Phone Idle: 4%
Cell Standby: 3%
Browser: 2%
MediaServer: 2%
Android System: 2%
Thanks,

I'm on the latest European radio (cant remember the code).
No I don't change anything in francos, but you can if you want to boot it some more.
And yes CM9 is just a nightly but super-stable still in my experiences, definitely worth trying for a week or two.
I'm on a gsm nexus stock battery running codename with francos kernel. 18.4. I just had a super heavy day, 12 hours and I'm down to 13 percent. 3 hours screen time plus 3 hours playing music with poweramp while the screen was off. No wifi - 3g hspa all day. Kernel set to 700/1000 conservative. Running juice defender on aggressive. 1 push email and one email set for once every hour.
If you are not getting acceptable battery life after running a custom rom and kernel with juice defender (not even sure if it helps) then download cpu spy and see if you are making it to deep sleep. 99 percent of the time it is an app.

Thanks for the suggestions. I do also think there is something that is causing this. I do get a heated screen also at times. I am running the FA02 for both CDMA and LTE which is the latest radio. I did change to franco's kernel but may go back to CM's stock if I don't find anything.
Also, I'm on 4G 24/7. No 3G area where I live and work anymore (Chicago) which is great but I think it eats up battery. Will report my findings after cpu spy.
Used 10% in 1 hr and 30 minutes.
Most definitely suggest CPUSpy. Another option is BetterBatteryStats to find out what has your device in a partial wakelock. I had an issue with my Desire Z prior to moving to the Galaxy Nexus where a piece of software attempting to access the GPS would get stuck in the background, and cause a partial wakelock. Going from 20+ hours of usage down to ~11 was a bit of a downer, but BetterBatteryStats helped me find the problem.
My battery is pretty bad too. I'm running Apex (latest) and the lean kernel (latest).
This is just from a few texts and emails:

Try running Codenamed Android and Franco Kernel.. I'm on my second day with this setup, and I'm really getting impressed. Running the stock battery. I have an extended one waiting to install once I've maxed out usage with the stocker.
Instead of starting a new thread I thought I would add to this one. My battery life just went from acceptable to abysmal and I also don't know why. I'm running latest Codename ROM with latest Franco kernel along with Gapps from 2/18. Kernel was installed after wiping cache/dalvik. I am lucky to get 12 hours without even touching the phone. Here are some screen grabs:
Please help me if you can!!
I'm no expert on radios but it looks like your signal sucks (all yellow) which can cause an insane drain on battery. Download cpuspy and make sure you are getting to deep sleep(your graph looks like you are watching a movie or 3) . My battery graph looks similar to yours when I use my phone constantly.

Sorry I didn't see that you have already downloaded cpu spy. My next thought would maybe it's just your connection. Try looking into flashing newer radios or disabling lte/4g, your area may just not be good for it.

Ran CM nightly with Franco's latest kernel and had some improvements but the battery on this thing is nothing compared to my extended Thunderbolt. I guess I was spoiled by that huge battery. How about CM's kernel? Anyoone has an opinion on that?
Having just the screen on will eat the battery at a 10-15% per hour. Using the phone, browsing XDA site, playing a game, using the Facebook app, or basically doing anything else eats the battery at even a higher rate. I don't understand when people say they are a heavy user and have 45% after 10 hours.Ccan't see that happening!!!
I'm using Juice Defender on aggresive, bought the BetterBattery Stat and nothing seem out of the ordinary, and CPUspy says that deep sleep is achieved when it is supposed to (over night 95% or more). I just think that this phone is a battery hog. I guess it's time to buy some spare batteries and an external charger. Any thoughts?
give this a try, it helps me a lot

Heavy users do not get 10 hours of use with 45 percent left so don't believe people who say that.. At most that is moderate use.

I'm using it for about a week now and the battery life is nothing short of fantastic to me. I get easily two days of battery life with normal usage. With heavy use and I mean using my phone almost non stop I get about 14 hours of usage with 4+ hours of screen time. My screen time is browsing the web a lot ( wifi and HSPA+) playing temple run and angry birds space and more web browsing.

It doesn't look like you used your phone for much during that screen on time.
Where can I find this kernel?
Anywhere around 4+ hours of screen on time is pretty impressive.
There are some who has gotten over 5+ hours with Franco and some other ROM combination.
That kernel looks pretty good, I'll give it a try.

Yeah but you gotta at least use it with minimum wifi connected and data used to extrapolate some usable data.
And just so people know raving about ogdobber's kernel it is basically stock. He is obviously a battery mizer so his tweaks are not for performance but using your phone. That said if you're nice enough, or donate I am sure, he'll bust a custom kernel for you. Do like his kernels though. Haven't tried many but his will get the best bang per watt.

I've had 8!!!
Screentime is only impressive depending on usage. I am not saying it is bad, I am saying it doesn't look like you used it much, while the screen was on.
What did you do during those 8h? With stock GSM battery I can have 4h with dimmed screen using inverted browser over 3G and using xda app.

Not.a.single.thing.
That was my point
To be honest I highly doubt ant kernel can have significant impact on battery usage. It might affect a little bit but after all, it all depends on how you use it. The screen simply is the major power sucker on the hardware level, it can't be changed by anything.

I respectfully disagree. I think a kernel is one of the major factor of battery life. You will notice a difference between a stock kernel and a custom kernel while having the same usage. 99% of the time the custom kernel will give you better battery life.

I'm using it for about a week now and the battery life is nothing short of fantastic to me. I get easily two days of battery life with normal usage. With heavy use and I mean using my phone almost non stop I get about 14 hours of usage with 4+ hours of screen time. My screen time is browsing the web a lot ( wifi and HSPA+) playing temple run and angry birds space and more web browsing.

The same can be said about many of the other custom kernels as well. Even the stock cm9 kernel can achieve this. There is nothing better about this kernel than Franco or the like.

I'm pretty sure there are other kernels out there that offers maybe the same or better battery or performance but I'm speaking on my personal experience with James bond and having using it I think it's a great kernel.

I second your disagreement. I have been using the Franco Kernel for little under a week now and there have been some significant improvements (no screenshots to back that up though). The Kernel is the only thing i have changed this week so it has to be that.
Kernels play a large role in battery life, if you say otherwise you are wrong. But it's the combination of ROM and Kernel also
Anyways, it's opinion, but i don't think James Bond compares to some of the other kernels out there. I haven't used it of course so I wouldn't really know. But Franco, Glados, Lean are all top notch.
I was on Gummy 1.0 and Lean 3.2.2 and got 1 day and 9 hours on battery with 4+ hours of screen time. I'd say that handily beats this.

Lol. That's it? That's all?
bow chicka wow wow.
I'm using AOKP b40 with the kernel that it comes with and I'm getting terrible battery life. I flashed Popcorn Kernel and Franco kernel once, but I had the problem where GTA III and other games would not start. I tried flashing the /bin/sdcard file but that borked the entire sdcard from mounting in Android so I had to reflash everything through adb.
I looked at Better Battery stats, and my phone is deep sleeping and nothing is wakelocking for longer than 5 minutes. I'm down to 67% after 15 minutes of screen on time and being unplugged for 2 hours. Is it just a bad kernel and should I try something else or is it my habits of using my phone? I'd like to get a lot more battery life out of this. I'm using the Verizon Galaxy Nexus with LTE turned off, GPS off, and Bluetooth off.
Thanks!
While my battery life is not as bad as yours, I too suffer from poor battery life. I can never squeeze any more than 2 hours of display on time at 45% brightness. I have tried AOKP and Slim ICS but they both give me mediocre battery life. I heard there was a franconkernel release which was by far one of the best released (r158?) I'm beginning to think I have a faulty battery as some people manage to get 4 hours of display time with descent standby.

Five minutes of keep awake is a lot for two hours.
I'm looking at Kernel Wakelock in BetterBatteryStats and it says PowerManagerService for 49 minutes. I'm at 54% now. I've been playing cached music for about an hour now with Google Play. Is there any more information I can give to see if I can rectify this problem?
Power manager is just charging. I would say that is a real issue though it shouldn't have dropped that quickly. What governor what frequencies and under volted?

I'm going to try with FrancoKernel and getting the sdcard file working properly tonight and see if it makes a difference. I leave it on overnight, it deep sleeps, but i still lose a good 15% battery. It's a bit ridiculous.
Do you turn data off? Do you have things that sync. Do you know if these apps sync even?

I don't turn data off, I keep 3G on. I have Facebook that syncs every 4 hours. My Google account syncs (not sure if there are intervals set elsewhere), and weather every 6 hours. Nothing else syncs to my knowledge.
EDIT: I didn't see your questions about my CPU settings. 1200MHz max, 350MHz min, interactive governor. I haven't touched voltages.
Okay if you can't live without sync your battery will always drain. Also change your governor to on demand or lazy if available. I usually just refresh everything manually and I get over 15 hours and 5 hours of display. Over wifi and maybe 2.5 of display over my terrible 3G speeds.

Strange......I'm in aokp b40 with popcorn kernel and the aggressive governor and just got a whole hour of screen time and was only down to 75%. It must be in app or something. Whenever that happens to me I do a factory reset and then reflash a different rom.

Glad to help. Yeah interactive is a heavy battery drainer. I like it's fluidity but it's not worth the amount of battery it drains I remember seeing this one day and changed to on demand and haven't had any drain issues since.

More than likely a variant of on demand. I'm not too sure. I never ran stock
But yeah interactive give keeps the cpu awake more. My favorite govs thus far are on demand, lazy, and pegasusq.

Ditch lean kernel. Do you have Chrome installed? It has an undocumented feature. It does unspeakable things to your battery. There seems to be at least a little incompetence going on in Chrome's code.

There's nothing wrong with Lean Kernel. It's running very well for me.

I apologize if I have offended you in some way. But anyone with any experience with troubleshooting will tell you that a problem is easier to pin down when you eliminate all unnecessary variables. And since I've read about and personally experienced anomalies with lean kernel, I suggested it first.

I don't have Chrome nor any custom kernel. I agree, cm10 battery life leaves much to be desired, even with juice defender installed. I hope it improves w/future builds. Battery on cm9, on the other hand, was awesome.

What version of CM10 are you running? I'm giving it sometime, but just flashed CM10 M1 last night, and am wondering if a change from cyanogenmod's kernel may help with battery. Got about 6 hours of lite-moderate use today on my I747
What things are you running in the background (NFC, GPS, vibration, haptic feedback, etc.)? I'm running CM10 9/15 nightly with ktoonsez's kernel with a 1.9Ghz overclock and my phone lasts from 8 in the morning to 1 in the morning. Today my screen's been on for just over 4 hours.
Another thing to check for is are you located somewhere where you consistently get good signal? If your phone is constantly reacquiring 3G or 4G or constantly searching for signal it's going to cause a severe drain on your battery.

I'm using SmartassV2 with SIO. I know I'm old school with SmartassV2, but comeon the name alone is worth whatever marginal performance increase I could get with some of the newer governors.
Well I notice that when I'm on screen, my battery drains like nuts. I slept 8 hours and I went from 100% to 88% which isn't bad at all, however if I'm texting or w/e, checking the web (keep in mind everything is off, I'm not a retard, and my brightness is at maximum low), battery eats like nuts. Is there a kernel or specific rom I should install?

This kernel? It says that if you install it, and you want to go back to stock, you need to reinstall the drivers. Wtf does that even mean? Where the hell would you even find the drivers. Sounds too high risk lol
I am running the latest CM10 build and my battery life is terrible as well. Wednesday night I was about 75% charger before bed and when I woke up, less than 7 hours later, my phone was off with no juice. I tested it again last night with about 85% left and it was dead again this morning. I have the same app installed that I had installed on stock and did not have these issues. I absolutely know and understand this things differ from person to person and settings to settings, but I am not sure my settings are that different from when I was on stock. I fairly enjoy the ROM, so I am just dealing with it.
Well, I've charged my phone to 100 last night, wiped battery stats (still on lean kernel), and i put my phone to sleep, and it drained only 8% which is very good (7 hours of standby). Now where my battery drains like a **** is during on screen time. I've put brightness all the way down to low, but I see people who get 20 hours with 5 hours of screen time. I could only wish to get such battery life lol. I wanna try that k747 kernel but I'm scared about losing my original USB and and **** drivers and I have no idea how I would go about restoring them if I no longer like the kernel lol.
CM10 battery life isn't that great. There was one nightly build that had outstanding battery life, but I can't remember which one it was.

If you both read his OP all you have to do to get the original drivers back is Reflash your ROM that has those drivers. It isn't a huge deal also to the guy going 80%-0 overnight, you have an app eating processes in the back destroying your battery.
