ROM with the best Battery Life?

Which Rom do u guys think has the best battery life?
My say is SILLIAN Rom but it was banned from the site.
So now I am using Virtuous.

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.

I'm getting nearly two days (40+) hours on CM6.1.1 stable. That's about the same as I got on stock.
I leave wifi on 85% of the time and my average daily use:
~30 texts via Google Voice
~20 minutes talk
~30 minutes XDA app
~60 minutes playing X Construct
~30 minutes browsing
~15 minutes Facebook app

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.

Galaxy Nexus Battery Fix

Hi,
I just got my Galaxy Nexus, flashed with AOKP build 18 and i gotta say that the battery life is unacceptable. It drops 10% in less then 1h while the phone is sitting there doing nothing. Wifi, bluetooth, location services, GPS are off. All background apps closed.
It lasts about half the time my iPhone 4 does and it is a year and half old.
I see some people showing examples of how their battery last for more then 20h but all these are BS tests as they leave the phone on standby all day or have some very light usage.
Is there a real fix for this? Am i forced to drop another 50$ and buy Samsung's 2100mh extended battery?
btw i tried setCPU also to lower CPU to minimum when in standby but doesnt do much. I want a solution that will enable me to use my phone, not something that makes it last 40h in standby and then kills it in 2h when i use it.
please help!

So everyone that posts four hours of screen on time is bullshitting? Did you know the first 10% isn't even that accurate? If you're on Verizon turn off LTE. If you're on GSM and you don't get three hours of screen on time you have an app that is killing your battery. It is as simple as that.

Try toggling Bluetooth on and then off, then grab CpuSpy from the market and check out if the CPU is pegged at a certain speed.
Some builds of ALL the custom ROMs have had issues where the phone wont sleep correctly, high %-age of Android System process, etc.
I disagree that its silly to talk about idle time on battery, because idle time is the closest we can all get to apples to apples comparison. We all USE our phones differently, the closest we come to using them the same is when they are just sitting there idle (not quite exact because some people sync data, some people only have 3G, etc, but a lot closer than person A playing games for 3 hours at a clip vs person B browsing for 3 hours)
I *still* havent seen anyone come up with a template like setup to report battery life. Like you said it does me no good to know someone dropped 3% "overnight" without knowing how long "overnight" is, if they had 3g/4g/Wifi enabled or even disabled completely, sync on/off, etc.
Personally, Ive seen 1.5%/hr drop with my phone idle. Running AOKP b19, LeanKernel, interactivex governor, undervolted (-75 mA at each level from 180 mhz to 1200 mhz), 4G on, BT on, GPS on, sync on (1 gmail account).
I imagine with all that stuff running 1.5%/hr isnt half bad. Screen on time isnt incredible but its not bad, but again my screen on activities can (and probably will) be different than your screen on activities so take that with several grains of salt.

It's not the first 10%, it's all the time.. it drops for about 10% or more every hour. Less then 3h of screen time.
I'll give cpuspy a try and see if some app is killing my battery.
I used AOKP rom because most of the people in the thread were saying that rom fixed their battery issue but for me it made no difference.

Yea somethings not right. Off charge at 8am and its 4:30pm now. Got 61% left at time of this writing and been using it quite alot. Typically have about 75% left about this time.
I just use an AOKP like yourself and a custom kernel. I'm on the phone like every 15min reading emails, SMS, word feud, twitter news, Facebook, Gmail.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV

It's actually 2000 mAh not 2100 mAh.
You can use a custom kernel such as Franco Kernel. New version came out today and includes more battery improvements (according to changelog!)

My phone essentially sits idle unless my screen is on...

As you can see, if my screen is on the graph drops, when it's off the graph flattens out and the battery barely moves. I used to be sick to my stomach of the battery life until I realized it was because I wouldn't put the phone down and always had the screen on thus killing the battery.

Just a word of advice. Whites consume more power on AMOLED screens. You'd probably maximize your battery a lot more if you went back to a "Ice Cream Sandwich" feel or at least apply a black themed MIUI.

I had something similar and it was recommended to me on these forums that I log out of Gtalk.
Before people come out and say it makes no sense - it doesn't really matter if it does or not - it worked for me. I get a full day out of a charge now, which doesn't really matter because as someone said above it's all relative. What DOES matter is that my phone is now sleeping properly, so the battery doesn't drain when the phone is idle. That's the part that wasn't working on my phone.
If you feel so inclined, give this a try and see if it works for you. Just log out of all Google talk accounts and see how your battery life is - you'll know within a day if it's helping.

Have you flashed the new radios yet?
You can also try different kernels and see which one works best for you.

Ah okay.
I think MIUI is pretty much at the same state as CM9. Just lots of work needing to be done since ICS revamped Android in so many ways.

not quite.
can i preface by saying that there are two types of Gnexus's out there? the SCH-i515 (CDMA/LTE Verizon) and the GT-i9250 (HSPA+, AT&T).
The 2000mAh is for the HSPA+ version
The 2100mAh is for the LTE version.
i see a LOT of bad advice on these forums here.
my best advice to you (from one Verizon Nexus owner to another), is to keep at stock 4.0.2. Root it, and apply a custom kernel. Only apply custom kernel if you feel that you're still not getting decent battery life for a whole day on 4G stock ROM/kernel.
As far as I know, Verizon Nexus owners' max on-screen time with 4G enabled all day is about 3 hours MAX, and thats if you disable everything else but LTE, with very low brightness settings, and on extended battery.
imo, the next 4.0.3 or 4.0.4 update hopefully will mitigate some battery consumption issues.

Are you talking about 3 hours MAX browsing or just being POWERED ON?
If you are talking about just being on for 3 hours, you are GROSSLY incorrect.

You were on wifi the entire day.
You are using the HSPA+ version of the Nexus. HSPA+ version gets better battery life.
Try being on HSPA+ the entire day with wifi disabled. you will not be getting 4 hours of battery life on-screen time.

I think the Kernel is what makes the difference. It seems to be the only difference i see between myself and the people like you have a reasonable battery life.
which one do you recommend? And i'm a noob at this so could you point me to a thread the explains how to flash it? If u cant its ok im sure i can figure it out.

Best ROM/Kernel for Battery Life?

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.
Sent from my Galaxy Nexus using XDA App

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.

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.

[Q] Terrible battery life?

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.

I'll give turning off sync a shot ... and changing the governor. I'll experiment tonight though. Thanks!

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.

Thanks for that advice! =D
Would you happen to know what governor stock 4.0.4 uses? It seems that my bad battery life began happening after I flashed AOKP.

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.

Hopefully using ondemand fixes my battery issues. Otherwise it's back to stock for me. (Shudder)

Oh it will. I had the same experienced when I first rooted I noticed an abnormal amount of heat and was using interactive. my battery would drop like a rock. Changed it to Ondemand and I couldn't feel anymore heat... especially while on the charger.

CM 10 Battery Life on GS3

My battery life on CM10 has been terrible. I have barely anything running, i've even installed this custom kernel to combat battery life
http://forum.xda-developers.com/showthread.php?t=1845836&page=31
and i'm still experiencing terrible battery life. my phone drains in an instant. is there anything anyone recommends?

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.

What..? I never even pretended to be offended.. lol I understand that I was just saying the way you worded it was as if Lean Kernel was the cause of OP's poor battery life.

I do have chrome, i guess ill use firefox

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.

Hmm, Im using CM10 nightlies AND lean kernel, and my phone seems to last well beyond my expectations.

No problems for me. I get 4-5 hours of screen time and 16-18 hours overall.

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.
