I figured I'd make this its own thread after speaking with several people with the same problems using a CMOD 5.0.5.3+ rom. This wasn't a problem in lower editions from what I can remember in testing.
Idk but I believe it is something in the kernel affecting this problem with the display hogging my battery. Even after flashing an undervolted kernel I still can only last 24 hours with an extended life battery, vs a weeks time before. And the display problem has been like this in all CMODS test .6 Roms as well so idk if it is in the process of getting fixed or simply overlooked. And other Rome work well but are slower it seams.
The display settings doesn't matter auto or manual its about the same. So devs what can we do to find the change or what can I do to help?

I'm running test 3 of 5.0.6. Today i read a book with fbreader for around 2hrs on it whilst on the train, had 2 30 minute phone conversations, around 20 texts, a dozen gtalk messages, and played blackjack for about 20 mins. i'm also using pershoots OCUV kernal, and after 11hrs without being plugged in I am at 75% battery. I'm happy with that.
I think it is a work in progress, as each new build comes out it's better. His testing builds are just that - testing. None of his release builds I have ever had an issue with either, although maybe my phone ue is a lot less than others I dunno. All i can say is i've never been tempted with another rom since early days on my magic phone Cyanogen rocks!

Nope, I have it on auto-detect, so quite bright when on the train and outdoors. I have setCPU (market, paid) running and set battery profiles - although I haven't hit them yet. I have it set to max 1.1ghz 100% to 50%, 998mhz from 50% to 40%, 776mhz from 40% to 30%, and under 30% to 500 and something.
I do use an app called autostarts (market, paid) and have set everything but system services/apps to not run on any kind of state change or startup. I use Advanced Task Killer to kill apps as soon as I finish with them.
But i've had all these for ages, I just think a big improvement on the last release test 3
Nandroid your existing and try out test3.
I've been experiencing the same symptoms with my battery usage generally dominated by the display. I'm using a UV kernel currently (intersectravens) so we will see if the same happens.
KingKlicks's DESIRE rom doesnt have the same problem it seems and the battery usage is much better.
Wondering if there is a underlying issue.
after .6 test 3 the battery has improved decently, still the display is hogging battery life more so than in the sense rom
Same thing here... Display totally kills the battery with CM5.0.5.3 and OC/UV kernel. Phone rarely lasts over a day with moderate to low usage...
Without usage I can barely get a days use :s
I get the impression that its not the display. I can have 50% display usage, sleep my phone while playing a MP3 and then have more than 50% usage... suggesting that its either he display+something in one category , or there is a bug.
The stock ROM always showed display at the highest usage also. I'm not saying that there isn't an issue, but remember that those numbers are all relative.
I'll say this: I charge nightly to prevent my battery "deep cycling"....That being said I un-plug at 8am and plug-in at about 11p-12a, I use my phone a TON.....usually when I plug in I have about 45-55%.....Not bad at all.....
I originally thought display being the main battery hog was a bad thing.....Then I thought about it a bit......
Would you rather the "system" use more batt? Cell Stand by?
Display (by all rights) should use most battery. More usage=Less time with a fully charged battery.....
Im using CM 5.0.5.3 and I switched Roms after using the stock for 3 months. As soon as I moved to CM I immediatly noticed the battery life was lower than before. I hope you find an issue to this problem ASAP.......I love your ROMs CM, but I love my battery life even more
Good luck with this !!
"display" = gpu acceleration and actual amoled power
Something else i just noticed, very odd. I had 41% display and 23% spotify.... i had been playing for music for a while (offline only). When i quit the spotify app... the entry from the battery usage vanished and display took a spike to 65% ish... really odd. Almost display is showing usage for a group of things.
What? How ? I get 6 hours maybe 7 if I'm lucky out of my battery.... even b4 my nexus was rooted ... how r u guys gettin 24

Ignore any figures people quote - battery life is always relative. One persons 'usual' usage is different than yours. A friend of mine brings his N1 to works and it sits on his desk syncing email - he gets 1 full day.
I bring mine, sync 2 accounts, play a lot of podcasts, have a RSS syncer going and use twitter and FB loads, i get a LOT less.
Dont worry to much, your usage figures are pretty normal depending on your usage patterns.
They say your mileage may vary for a reason
Battery Life
My Battery life has always sucked. Maybe I should buy a new Battery?
If I take my phone off the charger at 7:30, and don't plug it in all day, then I will be at about 30% or less by the time I get home at around 5:30. Unless I don't use it. But I use my phone to play stream music pretty much all day. Or at least 4 hours. One day I forgot my USB cable and I was below 20% by 3:00.
It is still better than iSuck, I mean iPhone, and worse than a BlackBerry. I have electricity everywhere though, a car charger, and an extra battery is like 25$?
So what is the big deal? You have the equivalent of a desktop computer from like 2002 in your pocked running off of a batter the size of a credit card, how long do you really want the thing to last anyway?
this is the only reason i hate CM7. it drains battery like hell. yes, im already using "conservative" cpu governor and have JuiceDefender installed.
when i was on the stock LG rom, battery life used to be about 3-3.5 days on normal usage. after flashing with CM7 (the latest stable version), i need to charge it every night. if i do a lot of net surfing, battery will last for only 15 hrs.
is there some other gingerbread rom with which i can get back the normal battery life?
ive never tried this rom but ive read that rjtchn's cm7 has good battery life. the last time i checked his rom isnt on xda but u can google his rom

First, you can go back to Froyo by flashing the stock ROM through KDZ. But all your data would be wiped out. Take backups.
And regarding battery backup, I think 25 hours of battery backup on moderate-heavy usage is fine. I'm not sure whether we can get 3 days on froyo with the same usage. I didnt use froyo much as I immediately rooted my phone and flashed CM7 based ROMs.
On Andy's ROM with Andy's kernel, I can get 25 to 30 hours with heavy usage, with 6 hours of sleeping period in between. So it is 20-24 hrs of almost constant heavy usage.
void. #forever
I'm using void. #forever with Franco's v18 BFS kernel.
I had 2 days & 20 hours with moderate calls, SMS & browsing. I think I could have reached 3 days until an exercise app surprisingly kept my phone awake & drained the remaining battery.
Using GB 2.3.3 - at the moment for testing purposes GingerCriccoROM 1.2 and latest Franco GB kernel. 3G data always on, sync on, (fb, twitter, gmail, email etc. autom. check every 30min.) Calls, sms, browsing, pretty heavy use and i got after first full charge and battery stats wipe 1d 14h - still 6% left. OC 480/729 smoothass. Still testing - at the moment i have 30% battery left after 1d and 7h.
i run void #forever and franco kernel
it usually last about 2 days on average (48+hr), i dont use the phone functions that much, mostly just browsing the news and sometimes GPS when i get lost out there, but i keep wifi/background/sync always on since i rely on gmail/gtalk/gvoice heavily
horrible battery life
flashed rjtchn's cm7 just now. And havent even restored backups yet. And as I surf on xda now on my wifi, battery is decreasing by 1% every 2 mins in front of my eyes.... it was 100% at 5.35pm and its 89 at 6.04pm now..... WTH is happening? Also to mention, I had bought my phone only a month ago with incredible battery till I started flashing Roms...
I'm using. Rover theme. Does that have. Anything to do with battery?
I had wiped battery Stat when my phone was in 100%, then I flashed the rom, rebooted, and then connected to USB mass storage for 20 mins to do transfers. ( it got charged again). Anything wrong in this process?

I am wrestling with battery life. Not being able to run 24hrs on one charge seems silly to me.
To use some round numbers, from best to worst given my standard usage patterns: {0}
48 hrs (2% per hr drain) -- stock LG 2.2 ROM rooted, crapware removed, SetCPU onDemand 122-600. Consistently runs 48hrs on a full charge.
24 hrs (4% per hr drain) -- stock ROM as it came out of the box.
18 hrs (5-6% per hr) -- CM7 RC1 unchanged. It seems closer to 5% per hour when I set onDemand in CM perf settings to 122-600 and tore out the launcher (using the delightful Zeam instead)
I can go to sleep with my OptT on the bedstand and wake up 8 hrs later and it's dropped from 100% to 60%.
I did do a brief test of Void forever and like the cleanliness of it. But development appears to be ended so no hope of BT working well or battery optimization. If I had an extra T500/509 I'd send it to the dev so he could continue testing. I did run it for a few hours but after I tested BT I didn't have the heart to go install all my crap on it for extensive testing. {EDIT: going to try it out today and see if I can hit 48hrs with it}
I am a big CM fanboi so I would love to hang in there with Mik until BT and battery are better. I mentioned battery drain in a (pre-CM7RC1) thread once and it was not well received, so I haven't mentioned it again until this thread.
If BT and battery don't eventually get improved (and I assume they will) I'll stick with the stock, rooted ROM.

i checked. the only "app" having max. usage is android system . and it is a fresh flash. i had formatted the sd card also. and i dont use mobile data or gps, i use only wifi. and im not on a 3g network (because my operator hasnt even launched 3g ).
now the time here is 9:22pm and batt. is 63%. the only thing i did was surfing and mail checking on wifi.

I'm on gingerlol with paolos kernel. I use my phone for a few messages a day and about 1 call per day. Playing around with the phone depends, somedays more somedays less. Battery lasts 2 to 3 days. Can't remember having more juice on stock froyo.

Same here! Just remember to change the governer to sth like on-demand or conservative!
Well... reading you guys talking about 2-3 days of battery life makes me think that I'm either doing something wrong, or my battery is a bit damaged, 'cause the only way I could think my Optimus One would last for 2-3 days would be with no use at all.
I got this phone from a friend who had owned for only 2 months and the phone was already rooted and with a custom ROM already installed (Light 2.2.2 which is fairly close to stock). With that ROM the battery would last for a day max.
Shortly after I started installing other custom ROMs and testing them:
- Devoid Froyo Final: The most responsive ROM I've tried, but I had horrible battery life with it, with only around 18 hours of bat with moderate use and 3G on.
- OpenOptimus: Seems a bit laggy to me, and battery life was not even better than Devoid's
- LOL 1.4.2: I finally settled with this one. The ROM is pretty responsive (although not as snappy as Devoid) and at least with this one I can have a full day of battery life (sometimes a bit more).
I must say that I always keep an eye on apps running in the background and stop those I know I don't need always running. I also use Titanium Backup to "Freeze" apps that I know I won't use on a daily basis (like Google Maps and Navitel GPS).
The other thing I'd like to mention is that I keep GPS off (unless I specifically need it), but I always have data ON, either via Wifi when I'm at home, or 3G when I'm out of home. My Wifi Sleep Setting is set to "Never".
The only two apps that I know are working regularly on my phone are:
K9 Mail: Receiving mails for 5 Gmail accounts (all configured as PUSH so that shouldn't drain much battery)
Whatsapp: Receiving messages from friends and family, but that app is also PUSH so battery drain should be minimal also.
Overnight drain with Wifi On is about 5%
What do you guys think?
BTW... probably during this week I'll flash one of the 2.3.3 based ROMS (GingerLOL). I hope that being a "LOL" Rom it would be as stable as my current one.
Not a long test, but I did put all my apps back onto void #forever for an apples to apples test.
Set it on my nightstand and we both slept for 6 hrs. 100% down to 66% in 6hrs, for a drain rate of 5.7% per hour. Gack.
I suspect the real killer is the broken CM7 bluetooth stack in our devices at the moment, but since I use my phone gets used as a wireless mp3 player most of the time I really need it. When CM7 for OptT gets a fix for BT I think It will be nearly perfect for my needs.

my battery life isnt that good either. but then again more performance=less battery life
Void #forever is truly the best rom I have ever tried.... The best thing on it is that its "void" and u can choose which stock aps to install. Thnx a lot guys for recommending me this rom.
Rjtchn's rom had better performance. Quadrant score was 1005 without overclocking(i don't remember the exact). Void's score is 840. But it has incredible battery.
Its the first rom I have ever seen with cell standby having the max bat. usage on 2g network. (all others had android system). That means just by putting on flight mode, things would go even better

It's a balance issue, I guess.
I was researching another issue and so set my phone (as described below) down for 20hrs 23mins and it is now at 84% battery. 23.3hrs / 16% battery usage = ~0.75% per hour.
Compare that with 5-6% an hour I was getting with CM7 on the bedstand. I suggest that CM7RC1 is , despite it's general wonderfulness, not providing 6x the performance for 6x the battery drain.
I am a CM faboi and have done the "buy Cyanogen a beer" thing on his site. I eagerly await CM7 going gold for our devices, and I hope the battery/performance balance is on parity.
Hi all, I'm new to this part of the xda forums as I had a nexus before, just got the upgrade to the Atrix, rooting,unlocking of bootloader everything went well but I just flashed Aura's from with feux kernel and im getting really really bad battery life, like I'm talking 4-5 hours. There is one process thats really confusing me, its just called "x" and its sitting there taking about 35% battery, my screen is taking 55% battery.
It's getting really annoying as my nexus used to give me about 12 hours and the only reason I moved to the atrix was to get the better battery life that I saw with all my atrix touting friends (they all had 1-2 days battery life) I'm about to flash homebase and see if that fixes it but I don't know whats going on. I have a UK MB860 and I used http://forum.xda-developers.com/showthread.php?t=1196747&highlight=t-mobile+root to root. Pleaseee can someone help!
X is the webtop and there is a fix somewhere for that (doesn't completely work). Just flash CM7 beta. Its much better than any other ROM and has the best battery life. Everything except the finger print scanner and webtop work.
Also I had really good battery on the Ying Yang ROM.

I think I might give CM7 a go you know, I loved CM on the nexus, even after it killed the memory chips it was still good! Im going to try it, is it really stable?
EDIT:
since updating to CM7 and Wiping my battery stats I have some how gained 39% battery!

battery stats
I've had great battery life on the atrix, now I'm getting a good look at the atrix on the 4800mah battery. I'm a heavy user and I could not get over 24 hours. And now I have 59 hours and I have yet to actually see how far I can take it. Cm7 beta. Juicey....
I find that all gingerbread roms have horrible battery life compared to froyo on the atrix. Cm7 battery is worse but the phone is smoother. Faux 1.3ghz kernel has even worse battery.
Regardless of the radio or magical method of resetting the battery state you use.
1:25 screen time and at 47% battery. Been off the charger for 6:15. It will make it through my 10hr shift with about 20% remaining if I'm lucky, usually I just toss it on the charger.

I was just about to post that lol. Also make sure every time you flash a new rom you are at 100% if not that is a sure fire way to cheat yourself out of battery life. I don't know if I'm just one of "the lucky ones" but I easily get over 16+ hours with moderate usage. I'm running CM7 beta with quite a few things frozen.
Ok so I followed the guide to perfection and it didn't improve the battery life one bit! I'm trying hard to find a t-mobile radio I can flash as I have read around it could be my radio that is the culprit and I am also getting rubbish HSDPA readings, I should be getting full bars but since switching to homebase Im only getting one bar.
Using watchdog I have noticed that the Xorg process is using over 50% cpu which does not seem right to be and I believe that because its a linux process Watchdog can't kill it. Is there anyway of fixing this?
1) Uninstall Tango, Facebook and Handcent SMS if any of the three are installed. They are huge battery drainers and you can find less battery hogging substitutes
2) Freeze any unnecessary apps, I believe there is a thread somewhere in the General section that has a pretty decent freeze list (if you flash CM7, you will have very little to freeze but that's good!)
3) Keep brightness down to a minimum when you can, I've noticed kicking the brightness up rather high can be pretty demanding on your battery
4) Set SetCPU Profiles to something like this...
Screen Off 216/216
Charging 1100/216
In Call 456/216
Battery <20% 456/216
Battery <10% 216/216
5) If you have the proper kernel set the CPU govner to power saver.
6) Undervolt, test yours and never apply set on boot unless you are positive it's stable, mine are something like this...
1100 MHz -50mV
1000 MHz -50mV
912 MHz -50mV
750 MHz -50mV
608 MHz -100mV
456 MHz -150mV
216 MHz -200mV
This way when you're phone is idling with the screen off, in a call or low on battery it is undervolting heavily to save maximum amounts of battery
With this setup I can get 30+ hours pretty regularly with moderate-to-heavy usage (weekdays/non-work days), 22-25 hours with more heavy usage (work days) and close to 48 hours with little usage (weekends).
It all depends on your usage and your phone but I have found this setup here to work fairly well.
I am currently on CM7 Beta, stock CM7 radio and stock CM7 kernel, running at 1100/216 when above profile conditions aren't met. 32% been running since 9 am this morning, it is now 3:15 am, today was a long workday.
I can almost guarantee (almost) that its your rom/kernel combination. Had same problem til I changed.

fastboot erase osh
That will nuke your webtop & fix your problem.
I'm now using faux kernel for CM7 and that hasn't improved anything, in fact I think it it has made it worse. It's getting really irretating because using the watch dog app it always says there is one linux process on every rom I use that is clocking at over 50% cpu usage and It won't let me kill it (probably because it's a linux process), its really annoying me because all I want is my phone to work properly but to enjoy the full rooting experience. I know countless amounts of people with atrix's and they get a full day and a bit out of their phone with heavy usage i can't even manage 10 hours!

Watchdog eats battery like a mthrfckr, get away from that. Install BetterBatterStats instead & look for wakelocks. Which linux process are you noticing with that high cpu usage?
How many hours of screen time do you get in those 10 hrs?
Have you tried with a fastboot wipe & internal storage format prior to installing a new rom? Are you using the latest recommended radio for your phone?

Turn background syncing off if you are using that, and get in the habit of doing manual updates.
Too many times (with ANY Android device) people leave background syncing on and it tries sending/receiving data in a weak signal spot when you don't realize it. That's like a hot knife through butter on a battery.
Leave syncing off permanently if possible! That's a huge improvement right there for anyone...

That's a bit radical, no?
I'd say use Green Power so the phone can update every half hour or hour. It's a smartphone at the end of the day..
I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?
Thanks!

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.
Note: Wifi is off.
Maybe 3G/H+ keep toggling for sync process?
I do use facebook! haha. and I havent used better battery stats

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
Hello guys,
I'm using cm 11 stable (latest) official for my i9300 with boeffla kernel 2.12 cm 11 NG. The system is quite stable as i'm using "Battery saving" profile ie. zzmoove/ battery yank.
The problem is that the system runs very smooth usually except the games. The games on the other hand runs relatively well but all of 'em cause huge battery drain, say for example after running asphalt 8 for 8-10 mins the battery goes down from 80 to 70 or 68%. Even google music drains like hell, too. Same things happened when i was in 5.1.1 roms. I also have powernap, amplify and greenify installed. Other than games the system sleeps well and drains very li'l.
And it should be noted that my stock battery is 2 years old.
So, is it a problem concerning me only, or every one faces this issue? should i go for a new battery?
Anyone plz enlighten me regarding the issue.
Thanks in advance.
Gaming drain seems abnormal
Never tried asphalt 8 but playing NFS:Most Wanted or other battery consuming offline and online games will give me around 2~2 and a half hours of gameplay from 100% so 10 mins for 10% battery is quite abnormal
Thank u very much.. So can it be a battery issue? what do u suggest, should i go for a new battery?
How old is your battery? Because in my device (2 year old battery), i've also encounter battery drain. So I decided to buy new one. As of now, everything seems fine.
Sorry bad english.

Mine is also stock battery 2 years old and I'm no battery expert but I can also feel my battery degrading.
So yours might really be battery issue and it degrades faster due to your usage pattern?
