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.

[Q] Is it possible to get >20h with a non-SBC kernel?

Now, I do use my phone pretty heavily. My girlfriend and I text back and forth about every 2-5 minutes, all day, which will surely rape some of my battery. In addition to that, I do things like surf the internet, market, Gmail, no music, rarely games.
Is there any kernel, or ROM/kernel combination that has users getting >20 hours on a full charge with heavy usage? I always see people getting it with what they claim as "moderate" usage or they'll post screens and their phone is like 40% idle, 40% standby, which is silly.
Just wondering.

It is...on CM7...with Tiamat kernel...19 hrs at 55% left, 3.3.5, non-sbc. ; moderate usage.
With heavy usage, I had around 18hrs @ 35% left.

I knew CM7 had far superior battery life to Sense ROMs, but only tried SZ with it, not Tiamat. Guess I'll give it a go for a few days and see what happens!
That whole some users experiencing dead SD cards issue kind of worries me, but nothing a new SD card can't fix! Ha.
I see some people sticking with RC2 instead of going up to RC4. I know thgre's a changelog I can check, but is there a particular reason some people are sticking with an earlier release other than that they might not necessarily need the new things added in a later RC? Does RC2 have more stability or something?

Some people are just clinging to it, and don't like change, or they're content with what it offers. Use the CM7 final that was released, along with the Tiamat kernel, you'll be good to go.

Didn't know final was out! (I don't follow CM much.)
Thanks for the tip!
Will certainly flash it tonight!

This was the best I have ever seen my phone do. I didn't use it heavy, just somewhat moderate. Typically with this same combo I will burn through a whole battery in less than 8hrs at work. Of course I am streaming Pandora/Slacker or on PowerAmp alot. But this screenshot was on Myn's Warm Z Nightly with kernel netarchy-toastmod-4.3.2-cfs-nohavs-nosbc-suv-universal-signed. Set Cpu running 1036max/38400min OnDemand and a screen off profile of 652max/245min. The only things autosyncing are Google acct, HTC sense and everything else is manual on my phone.
Of course being in a strong signal/service area is key. At work my signal is weak at best and we have no wifi . This particular stretch of time I was at home for a bit (ok signal) and my in laws (strong signal) working on their car for 5-6hrs. I Then of course let it sit unplugged all night. But I did a lil web browsing, searching, games and otherwise calls and texts. I was pleasantly surprised. If I was in a good service area at all times I'm sure I could run my phone 10-12hrs on heavy use.

I don't see the point in spending some money on an extended when I'm just gonna go get the EVO 3D when it releases. I'll just spend my time trying to find the best combination for me.

try calibrating.
full charge...after light turns green check with battery monitor widget
then clear battery stats, unplug
use the **** out of it till it hits the redzone
plug back in full charge again *checking charge*
see how it lasts...

Ih they're using the same battery and there bit expensive anyway...

Enough said!

I would highly recommend setcpu. I do the same thing as you, mainly use my phone for a lot of texting, and maybe 20 mins of internet a day. I have my setcpu set to 384mhz when the screen is off. This alone saves a TON of battery during the day, and doesnt affect any apps or anything else. I also have step down profiles, so if the battery gets under 60%, it throttles down to around 700mhz, at 40% it throttles down to 500 mhz, etc.
I am currently on cm7, and I can easily go a day and a half without a charge. But when I was on Myn's rom, I could go almost 3 full days.

Are we sure the battery is the same size? Another forum said the pics showed a square shaped battery. I know it's supposed to be more mah than current evo battery. But maybe they are confirmed to be the same size and I just missed that info.

Why not use something like gvnotifier to send/receive texts using your google voice number. The program runs in the task tray area of windows and integrates very nicely with google voice.
http://www.daveamenta.com/products/gvnotifier/
The only issue is texts you send will not be stored on your phone. Both however are available via the website at google.com/voice .
Most of my texts conversations are relatively unimportant, so saving is not vital.

Funnily enough, just the next charge, I got 23 hours on Warm 2.2. Moderate usage, though, not heavy usage.

GVoice has always had such a terrible wakelock for me. Like, the wakelock was the amount of time since it had started the process!!!

I use an SBC kernel, but I didn't for awhile. Here's what I did:
1. Turn off mobile data when you're not using it. Background data takes up a lot of battery.
2. Turn down the screen brightness.
3. Keep screen off as much as possible. My best, with SBC, battery test is nearly two days and my screen-on time is only like 7 hours. Use it for what you need it for then turn the screen off. Display is one of the biggest battery users.
4. Don't use haptic feedback or vibrate. It takes more battery than making noise. Since you're a heavy texter, like myself, this won't seem like it's helping, but it is.
5. Get a kernel that undervolts. That user up there who said use SetCPU to underclock when your phone display is off is basically doing what kernels that has undervolt does manually. Undervolting does it automatically.
6. In my personal experience: CFS > BFS. I'm not sure why, I'm not a kernel specialist, but I use what works best for my phone (0004 Hardware).
If I were to give you a suggestion, it'd be Netarchy 4.3.4 CFS-Mor-Havs-NoSBC. It's in beta but I've been using the SBC version for a month now and it seems to be the best bet for Sense users. I don't know AOSP at all, so I'm unhelpful if you use that.

Getting REALLY bad battery life; looking for ideas.

I haven't ever had FANTASTIC battery life like I'm seeing from some folks around here... when I first started on Starburst (I didn't keep stock for more than about four hours), I was at around 70% at the same time. I'm currently on Calkulin's 2.0.0; about to revert to Starburst and see if it's ROM-related, now that I've given Calkulin's about a week with a calibration to no effect.
I'm currently undervolted by -75 on all steps, and this seems to have made it WORSE if anything, which I didn't think was possible for undervolting to do. I've been monitoring things fairly closely with Watchdog, and nothing jumps out at me. The phone signal in the pic doesn't look good, but I've been in all the same places as I was when I was getting much better life.
What interests me is that I'm seeing absolutely no usage-based change in battery life. Until that sudden dip you see up there, it was going down at the exact same rate whether I was using it or it was sitting on my desk doing absolutely nothing.
That dip started after I played Fieldrunners HD for about ten minutes during a break at work. After I stopped playing, battery life went into a continuous plummet.
I use Tasker (extensively) to keep things in check; generally speaking, nothing is active unless it needs to be, except for Wi-Fi which is always active as it's my primary method of detecting my locations.
Am I missing something simple-stupid here? If not, anyone got any ideas, assuming going back to Starburst doesn't magically fix it?

Not sure if this will help, but improved my battery.
(1) go to your email setting for each account and change sync update, I believe by default it's set up to check every 15 minutes. With 10 email accounts, it took a toll on my my battery. I changed all my accounts to 4 hours.
(2) best way to kill a task is by holding down home button, going to task manager and kill from there. Market task killers were making things worse for me.
Hope this helps.

Thanks for the thoughts! Sadly, neither of those really apply in my case. I stick with with the default Gmail app, which is all push, and I don't use task killers at all.

I'm running the stock rom with a custom kernel. I did notice that as soon as I went from stock to a different kernel I started to lose battery life. Maybe its something Samsung did? I am still a novice with Roms and what not, but nothing like this happened on my original Epic or my Hero. Maybe the yellow triangle isn't the only thing Samsung put in there.

Maybe the aggressive undervolt is causing your phone to ramp up to a higher state to perform the tasks? That drop is steep with how little screen on time you have

For as little as I know, that certainly sounds logical. I still wasn't getting as good as I would've expected even the UV, though.
I just flashed the EK02 modem with today's wonderful developments; I'm going to wait and see if that gets me better reception and thus better life. If not... now I'm not sure whether to try the new ROM first, or scale back the UVs. I want to try one thing at a time, since it's not urgent that I have good battery life ASAP. This gets me through my day, currently, more or less; I'd like to try and find my root cause so that I'm not just trying things wildly in the future.

Well, the good thing is that as of today, its possible to return back to bone stock and start again so you can mess with a few setups and see what works best for you. I have found that this is the first phone that uses the frequencies well. I haven't undervolted at all yet and I have had great battery life. I did the standard delete Sprint bloat, Social Hub and associated apps, Maps, etc. Also, get BetterBatteryStats. It may give you some insight into what's happening.

Then update to EK02

Got very slightly better today after flashing the EK02 kernel. 23% at the same time instead of 18%... anything could account for that 5%, though, so I don't really think EK02 had any effect on this. Zedomax kernel with stock voltages is next.

(From the market & assuming your rooted)
Settings
~Screen off profile max800 min200
~GPU to Conservative max1000 min800
~Nitrous Widget GPU to on demand max1400 min1000
What this should do is downclock your device when on standby by alot. Second for phone calls and daily stuff a clock of 1k will be silky smooth and be a small downclock. Third when you set up the nitrous widget and activate it you will overclock to 1.4k which is stoopid fast my quad score is at 1.4k I get 4500 scores at 1.6k oc but forget batt when I'm using the nitrous. I like too personally keep my phone at a clock of 800 for daily phone calls and web surfing... if I play a graphic intense game ill oc it with nitrous and not worry about burning up my phone because if I set the phone down it downclocks as soon as it stands by and will pick right back up when I'm ready.
Hope it helps here's pics.

If you're talking about the page I think you are, it'll have to wait until at least morning. I just did a full charge.
To wit... I spent 43 minutes on a phone call, and lost almost the same as what I normally lose in that same time period. 6% for a 43 minute call; I'm averaging 5%/hr loss doing NOTHING.
@Dchibro, assuming that's true, what would it mean for me? Does it give me a solution?

So, doing a bit of my own detective work... I've had Watchdog installed for about three days, with aggressive monitoring. I was almost immediately getting a bunch of alerts for two processes:
I initially whitelisted them through Watchdog, dismissing them as system processes that unavoidably needed to run. However, the comment from Dchibro got me thinking and sent me back to those, and I started Googling around. Here's what I've turned up so far:
http://goo.gl/Hsvej (HUGE thread on the issue in SGS2 forums. Haven't had a chance to go through all this yet.)
http://goo.gl/kUcqx (SGS2 forums.)
http://goo.gl/mlWW4 (Nook Color forums.)
http://goo.gl/mNiId (My Google search results.)
Gonna try some of the suggestions on here and see what I turn up. For now, I'm returning to stock voltages, implementing a bunch of those changes and keeping everything else as it is now to see where I end up. Phone will be charged to 100% before bed tonight, and I'll post sometime tomorrow with my findings.
Wish me luck!

So, in stead of waking up to 50% this morning, I woke up to 86%! Which is the same I went to bed at. Six hours of sleep, not a single percent lost. If nothing else, I learned from all this that I can reboot the phone when this bug hits me and and get away from it.

As I suspected. Your Watchdog shot clearly shows that you are/were (sounds like a reboot solved your issue at least temporarily) suffering from the Android OS bug. This bug presents itself most prominently in the suspend and events/0 processes. Unfortunately, a conclusive solution has not been found, but there are some things you can do to hunt the problem down.

Definitely seeing a bit of an improvement, here.
Watchdog alerted me to the suspend and event/0 stuff again about an hour ago, but I quickly rebooted and nothing seems to have come of it. I'm going to try to make a Tasker profile to do this automatically, kinda like Viper's LoS script.
All in all, I'm considering this a mostly satisfactory alternative to draining 80% of my battery with almost no use in eight hours.

[Q]Battery lasting suggestions

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:

I have frozen the maps app as well ( this was a major battery drain as it would constantly reopen) but it only gave me ~1 hour more.
Thinking of swapping out for CM9.

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.

I usually have good LTE coverage but I'll try tomorrow with it disabled. Also if I am using WiFi, will LTE still drain the battery?

Your signal is trash and you're having wakelocks

Maybe I'll try a new radio - I'm still on the original. Is there any other program besides Better Battery stats to find wakelocks?

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
i'm doing almost 24h on 4.0.2, can't wait for 4.0.5 or whatever

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.

[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.

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.
