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?

with setVSel I was able to extend the battery time to almost 60 hours !
with juice defender I got less battery time than without it (around 48 hours without and not more than 46 hours with juice defender)
So my choice is clear !

What are your settings and what is your usage?
Setvsel installed i noticed little hangs between clock speed changes.
I've made stability tests but testing at 300mhz sometimes the clock speed icon goes to orange (full speed) during the test even at default voltage.

default settings, only changed value [email protected] to 1000 MHz and run stability test for 30 Minutes -> without a problem and only 34°C
How can you people do 60hrs, with my moto defy, set vsel on 1. 18-300 2. 25-500 3. 40-800, i can do near 30hrs with single charge. I am online on GTalk all the time, and that is all, 10mins call, 30min browser and 1hr Gtalk chat.

Yes I notice the same and prefer performance mode to default on demand mode. Unfortunately performance mode is not remembered at the moment and has to be set every time after restart.

There is a lot of factors, too many to list. But, I'd say the biggest is the rom. I have two defy's, the wife's is running stock tmous 2.2 and mine is running Pays v4 which is blurless. Both are overclocked using setvsel at 30/300, 54/700, 70/1200 with 86% threshold.
I just got 55 hours with heavy use (wifi, mp3, games, talking/text, gps, etc)...had 34% remaining 48 hours in last I checked, but a few hours later killed it off with the mp3 player while running (and using a gps running app) the last couple hours. The wife's phone gets a a little more use from ereading and she is averaging in between 32-36 hours, which is about the same that I was getting before Pays rom.
In short, the more apps and services running in the background even when not in use...the more consumption. But like I said, there are a lot more factors at play.

True. Having SetVsel + Uninstalling useless or unneeded system services give me 2 days of battery under normal use, and turning off the wirelesss is making now a big difference, 2 days and 4 hours runnning on the same charge at still 55%. (i have to remark i am having almost no use of the phone this 2 days)
I have juice defender and setvsel together they work great i have no problems and my battery doesnt drains fast

Juicedefender is a really beutifull program. The problem is that it spends as many juice as it saves. Its pointless having it. I have 3 days of battery since i manually turn off-on wifi.

I have no evidence, but I kinda think the same...running another app to kill another app might be like robbing Peter to pay Paul. Since my last post, I've decided to go more minimal, got rid of task killer and setvsel and only using milestone (milestone is probably not needed either but can't go completely naked just yet)
The phone is still zippy and I notice it doesn't overheat as much. As for battery consumption, I haven't given it enough time to compare. But given that I'm not overheating as much is a big plus.
i have 3-4 days of battery under light-moderate use. i ussually dont have a chance to deplete it completely because i move pictures between laptop phone, or use adb to do stuff , so it always get some charge from USB.
Omg reading older posts i noticed some people don't realize the advantage of setvsel over everything else including milestone overclock.
First it can work as an overclocker like milestone OC but more important as an undervolter.
Stock values are 33 - 300 Mhz 48 - 600 mhz and 58 - 800 mhz
I go with 18-300mhz 30-600mhz 40-800mhz less volts longer battery life.
And imagine feed the cpu with less volts and at the same time overclock it for faster speed. Yeah. some people do that,
18-300 40-800 55-1000. At max speed you feed same power and get extra 200mhz.
If you use a task killer once, ok, but if the task killer is automatic and kill for you at intervals it worsen performance because android likes to ressurrect apps, it kills 12 apps, and in 60 sec bang, android revive them, so you enter an endless cicle of kill - resurrect.
And juice defender its a heavy app. eats too much cicles.
Oh and Turning Wifi OFF, or "Always ON". increased 20% battery life.

And about task killers, if its a one time use its ok, but if the task killer is automatic and kill automatically at time intervals it worsen performance because android likes to ressurrect apps, it kills 12 apps, and in 60 sec bang, android revive them, so you enter an endless cicle of kill - resurrect.
And juice defender its a heavy app. i see 5% total consumption in battery stats and i think that's a bit high for a program who claims to save battery.
Oh and Turning Wifi completely OFF and/or setting "wifi sleep policy never" . increased 15%-20% battery life. (wierd might seem but wifi sleep policy when screen is off is worse for battery)
Just wondering because right now I'm using GSB v2.6 and I'm getting max 6 hours of battery life through normal use like checking email, sms, casual browsing, and listening to music.

Have you tried re-calibrating your battery? Made a huge difference for me; it's good to do especially with a lot of ROM flashing, but even with just one it can throw your battery calculations off.
FYI follow the instructions to the letter, otherwise you might as well not do it at all IMHO.
I had the same issue using GSB 2.X. Switched to OMGB 1.1.1 and i now get 15 hours with moderate usage and no tweaks.

I've gotten over 30 hours before with GSB, immediately after a recalibration.
Your best bet for battery life is setcpu settings. As long as you're using froyo and gingerbread you'll get a boost.
I suggest Tazz as his ROM's have always worked for me. My setcpu sleep profile is:
min 19mhz
max: 480mhz
governer: smartass
and in advanced settings I have:
polling interval: default
Whatever the next one is: 98
Ignore smart or hwatever the third one is: 1
bias: 4
edit: With this I can get a good day or two of moderate use.
I found on GSB that that 19mhz is too low and the phone does not always wake from sleep. I followed workshed's suggestion of min 480 mhz with max 710 using CM7's CPU settings and all worked very well...that is until 2.0 when battery life went to hell. I recalibrated but i think the problem was my exchange mail app.
Oh, and with smartass you shouldn't have to set sleep profiles. Supposedly it's "smart" enough to figure that out
You can also try collins battery tweak, I use it on tazz gingerbread and it works awesome my phone used to die pretty fast before I tried it and now that I put it back on my phone I am very glad I did.
Im running GSB 2.8 but for me, all seems to be going well.
In one day, off a single charge, I've gone 12-14 hours at a time!
Make sure you always charge correctly, and don't abuse the phone's battery all the time!
Been trying out various ROMs and lately, I've settled on FroShedYo's Final V11 with CM6.1 as my everyday workhorse, stability over speed, and with a bit of battery calibration - getting an average of easily 20 to 30 hours off a full charge on OEM 1500 maH battery originally for the HTC Ozone (so it's about 15% higher capacity than stock's 1300 maH, which I keep as a spare/backup.)
With a bit of tweaking on CPU clocking (Ondemand), turning off vibrate & alert sounds/LED's, and email checks every 60 minutes (1 account only + Gmail pushed) and minimal widgets open, etc. - I can leave the house at the beginning of a long day, go about daily business, voice calls, check email checks, quick news & weather update, etc. and still have 25% to 50% battery life after an extended 12 to 15 hours day on the move, depending on how the device is used. I get a poor 3G signal at the house flipping to 1X often & back, and wifi OFF on the road (BlueTooth ON for driving but no Maps/NAV (ON at home.) In short, plenty of variables on how the battery is getting drained - in standby mode, clock speed is lowered so I could still be over 90 to 95% battery after 2 years but it will slide downward with active usage. After wiping/flashing & reinstalling all the APPS & fine-tuning the settings, I do a NAND backup and then do the battery calibration - and after 1 full cycle, I've been consistently getting these standby & usage time - which I can live with (C2C flashed and extra goodies on a 16GB SD card.) Yesterday, it was showing over 50% after 15 hours of light/moderate usage.
I've tried the latest nearly finalized GSB/GB Roms & variants, they are faster & fancier, but FC's, GPS issues & other minor bugs plus "not as good" battery life had pushed it back to 2.2 OS on the Eris. OMGB 1.1.1.1 and the Condemned CM7 just out this week are pretty cool - but battery life really slide quickly - unlikely to see more than 10 to 15 hours of usage out of a standard/non-extended battery.
The other one that I like is the Nonsensikal 2.2.1 ROM, troublefree, stable & reliable - the edge on battery yielding to FroShedYo's version ( keep that on another 8GB card along with the newest GB releases for "playing")
Otherwise, the xtrSENSES 5.x and xtrROM 5.x are fine as well for everyday use - performance & battery life-wise over the latest stock 2.1 ROM.
Those are my two cents for what it's worth, great work being done here and it's giving new life to the Eris, not quite EOL for some of us - played with the TB in the store, nice big screen & fast, but I'm not about to wear a "brick" phone going out on the job with an extended/bulky battery just for bragging about 4G/LTE. Mobile devices have come a long way, I still got my original analog MicroTac XLT with a 2200 maH tipping the scale at 10 oz in my bottom storage drawer.
On the sideline for a "polished" GB/GSB ROM with the bugs resolved and better battery life, and I'm off to flashing it on my spare SD to test it out. for the "adoption" usage.

How you guys get even 2 days of battery??
I am tired of tryin gall the combinations of settings / kernel / ROMS nothing has helped till date.
I am not able to get battery for a complete day. Freaking it drains it off in 9-10 hours.
There are users who are getting 2 days of battery with wifi/edge on at all the time, with overclocked phone, and many other options enabled. But I am not getting any of these.
My usage includes
* 1-2 hrs of music
* 1-2 hrs of edge
* frequent texting but can be summarized for 1 hr in a day.
* hardly 10-30 mins of calls
* 10-30mins of games
CyanogenMatt 1.1
franco kernel 19.4 gbs v18cfs
InteractiveX 480-600 mhz
all this is normal and way below average usage but still I am not able to get battery life. I hate recharging the phone after every few hours. Have searched forums tried suggestion but nothing worked.
Maybe I am choosing wrong combination of ROM / kernel , I have gone complete clueless now, any help or suggestion is welcome.

It is because of usage patterns. Based on your usage, I think its normally for your battery to drain just like that.

Thanks for replying terratrix,
but users are using continuous wi-fi and get a complete day of battery, I dont even use that. AFAIK wi-fi uses more battery than EDGE. Can you suggest me proper ROM+kernel combination?
I installed cyanogenmatt 1.1 thinking it would improve battery life but it didnt.

Well theta because they are using the phone less often. You are wrong , wifi consumes far less battery than edge. Wifi on standby drains minimal battery.
Sent from my LG-P500 using XDA App
It's mostly about background tasks. Install supercharger and a task killer to kill your tasks on screen off. Then disable unneeded autostarting applications with Gemini or Autostarts. This way I get about 1% battery for 4 hours without using my phone. And I strongly advice you to use 480/YourMaxStable with SmartassV2 as Smartass automatically manages the current CPU frequency. Your brightness should be between 25 and 50%. And also disable any unused at the moment radio (including mobile data).
how would I disable radio?
do you mean not using radio is disable it??
Well here's how my phone goes on for 2 days
android assistant app for cleaning memory every 10 minutes and for killing apps on startup
Advanced task killer for killing tasks(set on auto kill)
Antutu power saver which has some good features(puts phone on flight mode at night for few hours)
or use juice defender(has extra features)
try keeping edge/3g/wi-fi/bluetooth/gps off when not using(saves a lot of battery)
reduced brightness(40-50%)
and keep screen off when not in use
also keep OC freq at 729/480 its the best know OC for our phone performance and battery wise
and InteractiveX is well know for battery saving
(i prefer on-demand because of performance and gaming )
the above things help me use my phone for 2 days or i must say 1&1/2 day
with 4-5 hours gaming(3d HD games)
1-2hours browsing the net
few messages and calls here and there
on a full charge and normal usage at the end of the day i have phone battery at 40-50%
A radio is basically a wireless I/O device. GPS, Bluetooth, Baseband, WiFi, FM... - these are different types of radios. They drain power when powered on so if you want battery life you should simply disable the ones that you aren't using at the moment.
@viv_jen: There is no need to autokill every 10 minutes if you don't have unneeded autostart applications. Task managers also drain battery if used too often. It's also a good idea to use the long-press back key feature of CyanogenMod (It kills the currently visible task).
To pitch in my 2 cents worth,
I've found wifi uses quite a bit less than edge/3g data on this particular phone.
This phone has shocking battery life, even for a smartphone.
What you are getting seems about normal for your usage. My battery will be between 20 and 30% after 4 hours of music and 3g browsing. Once I stop doing these things it goes down at about 2% an hour on wifi, about 3% an hour on 2g, and 5% an hour on 3g. I ended up keeping my charge cable on me when I go places and actively use the phone, and "topping up" the battery when I'm sitting at a desk or whatever.
thank you guys for valuable inputs,
could the combination of ROM + kernel also help?
I tried cyanogenmatt + goldenleaf after some of the user suggested that it gives enough battery.
I also heard void gives a good battery.

yep it does
for me atleast
@nogav: WiFi drain depends mostly on Tx (Transmit) power. Mostly we receive information from the internet (Which means Rx is way more important than Tx), so after running a few speed tests (Speedtest.net app) at each option avaliable at the Wifi Tx Power app from market I found out that internet speed at a Tx power of 4dBm is roughtly the same as for 32dBm. Also, our device only supports 801.11b/g mode, so internet speed isn't the best thing about Optimus One (Excluding HDSPA).
@droidevil: The thing that drains most battery is Stagefright. It is able to play 520p mp4 videos almost smoothly, but it is a battery killer. Hardware acceleration also increases performance at the cost of battery, but it is reasonably balanced. Other things that depend on roms: number of preinstalled apps. Deodexed apps load faster, and the less of them there are, the faster the phone boots and runs. If you have about 100-200 programs installed, Autostarts, Advanced Task Killer and Supercharger are likely to be used.
thank you guys for your useful information..
Just raised all urs thanks meter for helping me out..
Well I have installed android assistant set to auto kill on every 10 mins.
Installed gemini and stopped the apps which are set to open on boot.
brightness is the minimum
480-728mhz with InteractiveX
so far 12 hours have passed by and have 50% left
Normal texting, gprs browsing, music no games though.
Lets see how far can I pull it off.

Nonono, don't use autokill, they are just crap, not needed, they drain more battery.

The ROM itself is very fast, just wondering which kernel will best suit the rom to give the desired battery performance.
Any suggestions please..!!!!!

franco
and use interactiveX governor(if you want for battery)
franco's CFS / BFS?
I have read around that fserve's kernel also gives good battery...
IMHO, actually your battery drain is actually pretty good for a usage like that, I am using more or less the usage of yours and everyday I have to charge.
So first a little background on this phone: my girlfriend had been heavily using it for 2 years. Over time, the battery went bad. She would keep it always on charger when she's at home, so she can have a full battery when she goes to school. At one point, after over 1.5yr, the phone started behaving weird when connected to charger: it would be either discharging while on charger, or charging very slowly, like 5% in 2 hours, during which the phone is on standby, not being used.
I took the phone and flashed a CM11 nightly. Ever since then, the charging problem has been resolved. However, the phone has extremely poor battery life. I'm able to get maximum of 2 hours screen-on time.
- I have the Greenify app, and most of the apps are greenified, including keyboard even.
- I have data off at all times, and am using Tasker to turn it on only when certain apps are running. Turning the screen off or exiting the app disable data.
- Screen brightness is at 50%
- Maximum CPU frequency is lowered to 1000 MHz (min is at 200 MHz)
- CPU governor is ondemand
- I/O scheduler is CFQ
- The phone is running CM11 nightly from 16/02 with it's native kernel.
I have recently bought a battery which is claimed to be an original. I don't know if it is, is there a way to actually check it? The battery life has not improved in regard to the old battery, the one that came with the phone.
I have also tried Gustavo kernel, but for some odd reason the drain was like 1% every 2 minutes when on standby, so I restored the latest backup.
Maybe worth to mention is that I have a yellow-ish rectangle going over my screen. It's not really noticeable, only in apps with white background. The rectangle is located in the middle of the screen, goes from side to side, and takes ~1/3 of the screen vertically. I have no idea what is that, but the screen is okay. It's responsive and the colors are fine.
I have no idea with else I could do to improve my battery life. It's seriously awful.
I'm going to try and calibrate the battery using this app tonight, but I'm really not too optimistic.
Any tips?

These are common symptoms of a damaged usb port. It was the same with me, until i replaced the usb port. Now my S2 works, battery wise.

You should try different Roms like slimsaber 4.4.4 by fusionjack. I know i've said this particular line many times before (to others) but it has now become one of the first things I say. AFAIK, the last few cm11 night lies weren't particularly stable or battery friendly. You should try a custom ROM with a different custom kernel (i have noted that you've flashed gustavo kernel) like apolo kernel 7.2 beta 3 by pedestre or dorimanx 10.44 v008 by cybernetus.
