[Q] Terrible battery life with CM7 - LG Optimus 2x

Being disappointed with the bad battery life since the stock GB update (which took like 30% battery idling over night, vs 10% in Froyo), I installed CM7.1 stable. However, things went to worse, and CM7 took 75% battery in 8h after a full charge and a reboot! I tried since the last nightly and some older basebands, and left my phone with ~50% battery in the evening, only to find it shut off (because battery depleted) in the morning!
I suspect it's caused by 3G, because if I disable mobile data, the phone consumed only 1% in 2h of idling.
Does anybody has this problem too? Any advice?
Thanks!

Try the latest nightly 204.
The battery lasting as with the original GB ROM.
I am on the nightly 204 since few days and it is OK from the battery side.

Thanks for the reply!
I already tried 204, but it was the same. I also tried a lot of different basebands, but all were draining battery. I used smartflash to flash v10b, and then flashed the v10f kdz, the last that didn't drain my battery off. It contains BB 725, which I also had tried with CM7.
I'll try to restore the CM7 backup to see if it still drains my battery and keep this thread updated with the results.

check with spareparts what is using the battery (partial wake up). I bet it's google maps latitude!

There is a Google maps entry, but the usage is minimal.
So after 6h on stock v10f that consumed 5% I restored on top of that versions BB the cm7 backup. With a few minutes screen on (me checking the consumption), my battery bleeded 9% in an hour!

I have exactly the same problem :-(
No idea about that...
No special entry in battery consumption.

Yesterday I downloaded this http://uploaded.to/file/tgpilbek Kang on my O2x and that is best rom regarding to battery life which i put on my O2X in few weeks. In 24 hours of moderate use i am still on 70%. And everything else just work fine. And I must say that i tried bunch of roms lately, from all 20L to all CM7 kangs I could find.

I already use this kang since 3rd dec. Problem is still present.
Also tried different kernels with 203 nightly like swiftextreme or vork. No noticeable battery improvement.

Look at the details, how much time did it run? 15m in hours could drain the battery so much fast!

post your signal strength in 3G or 2G, and then post your betterstats screenshoot for wakelock activity. then we can predict what is the problem.

I flashed o lot of BB/RIL combinations, so I cannot make the screenshots. In the partial wakelocks submenu there was a Maps entry, and it was like 5s for like 6h, so I supposed that wasn't very much.
Right now I'm trying the combination BB from V20C (VDF Romania) with RIL 606 from V10c Euro Open, which seems to behave somewhat better than other tried combinations.

[Q] Bad battery drain, new SGS, tried everything

hello,
i've had my SGS for a little over a week now. from day one i noticed battery drain but i thought it was normal for a new device. i flashed darky's 10.1 extreme on the second day i got it because it was very slow and had a lot of bloatware ( i wasnt very patient and i flashed at 95% or 96% battery), the drain was still there. i let it go through a few recharge discharge cycles and no improvement, so i used an app from the market called "batterycalibration" by marosige, no improvement and it the reading would drop to 99% or 98% after taking it off the charger.
i did a little digging and discovered i had the android os bug (was over 50% usage usually) so i used titanium to wipe software update and samsung account, and froze the first, didnt help by much
i then flashed darky's again at 100%, and now it still reads full charge after removing charger and android os bug i gone (reads 4% system and 4% os), but drain was still there. i emptied it to the point it couldnt turn on anymore then charged it from wall charger while turned off to 100% while i slept
i woke up and tested it by playing a game (Blastmonkeys) for like 20 mins and the battery went down to 90%, that was less than 2 hours ago, and now its at 87% and it was completely idle
notes:
my brightness is turned all the way down with no animations but display reads 54%, wifi is usually on when im home but battery stats show 6% wifi so i dont think its a big problem
also, the device was bought locked in france by someone else and im in egypt, so i dont know anything about warranty..
im sorry for the long post but i tried to be as detailed as possible...
hello,when i upgraded my sgs to 2.3.3 i also got battery drain and android os was consuming hell lot of cpu about 70%,..,.,then i flashed 2.3.4 jvp i didnt get any battery drain in that firmware then i upgraded it to 2.3.4 jvq this also donot have ny battery drain..,,.i recommend u to flash it and try it once
will try, but isnt darky only compatible with JVH? what happens if i change to JVQ?

see jvp and jvq are bug fixing firmwares and i didnt use any custom rom ,..,i have stock firmware which i just rooted and didnt use any mod or rom.,,.,.jvp and jvq are stable roms diffrence between the both is that in jvq browser is improved gallery improvement,.,..,etc
As far as I know, the percentage not being 100% after unplugging is normal. To prevent wear on the battery, the phone cuts the charger after reaching 100%, and restarts charging when it reaches ~95%.
I don't think a 3% drop in battery over 2 hours is uncommon. Wifi and data connection will pull a lot of power if on, even in standby.

Normal, this phone drains about 20% battery per hour of screen use, slightly less when watching video.
2-3% drain over 2 hours is also pretty normal if you have wifi/sync on.

I just got my SIM card replaced today. The one I had used before was about 12 years old. So whenever you-re having battery issues, make sure your SIM card is not the cause for it .

Horrible battery life

Hi,
as I got the phone I already had bad battery life, so I made a factory reset, maybe it helps. It didn't, 1 hour of playing(not even 3d game) ate 40% of my battery, on 2g network and 40% display brightness.
I decided to put on the EURO open(jun 25) and root the phone. I uninstalled a couple of system apps(car home, unused apps, etc), and also put on minfreemanager on agressive settings(to kill background apps consuming battery).
It helped absolutely nothing. I disconnected the phone from the charger in the morning around 6am, and by now with approx 20 minutes of gaming, downloading it's only 75% left.
I also discharged my battery 2 times to 0%, and turned on repeatedly to kill the battery, and once recharged while it was on, once recharged while it was off. Helped also nothing.
some info if needed:
baseband: 1035.21_20110725
kernel: 2.6.32.9
build: FRG83G
LGE ver: LGP990-V10d
Please help, it would be such a good phone without this battery issue ((((((((
Install juicedefender
Sent from my Optimus 2X using XDA App
I installed it in the stock one, but it didn't help.
As I see I have problem when the phone is active, and I do something with it.
When my phone is sleeping it seems okay tho.
I played stupid zombies for 10 minutes just now, and it went down from 70% to 65%. This means every hour battery dies 30% which is actually 10% better then yesterday with the stock rom before this open EURO. It still is pathetic, that you can only play 3.3 hours and your battery is dead
My SGS was able to hold on at least until 5 hours with heavy usage.
I don't know guys my phone can last for 3 days only using for phone calls. Watching 2 hours of youtube can last 2 days.
Maybe because i don't use any Internet via mobile network.
I don't use task killers. After reading this http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
I always charge the phone when the battery goes to 0%.
Autobrightness is always on.
Always use 2G networks and Data is disabled.
Useing Modaco Fear edition 12.6.
with baseband 622.
with TW Launcher.
5 Homescreens full of widgets.
and useing Watchdog Task Manager for monitoring what app uses cpu most.
So im very happy with my phone with heavy use i can still manage 24 Hours (Browsing, playing, Youtube). And maybe 6-7 hours of max usage.
I had about 5 hours of battery life on idle when I first got the phone brand new. I'm getting about 40 hours on idle now with Fear 12.6. I'm still testing whether underclocking cpu while idle will improve battery performance. But i dont use any app-killer and do NOT use JuiceDefender, it doesnt work well with this phone. Havent updated baseband, using stock _20110405, make sure you have matching RIL to baseband, so dont simply update baseband.
Try cronos Tom, it has been optimized battery driver, I've just bought brand new 2x 2 days back, my battery was lasting hardly whole day with 2-3 hour wifi usage then i read somewhere its a known issue with with 2x, not same like ur case, then I try various roms the only rom that gave me longest battery life on my phone is cronies mod, try it

battery drain help!

just a question again, I'm on onecosmics 4.0.3 battery drain seems to be huge, even on standby i get only 6hours max usage? where i used to have darky to last me more than occasional 15hours using heavy...
is this a bug or is it just me? :S and what is the best ROM for battery usuage? ive heard and had many revies but cant seem to be able to conclude or justify to one!! D:
please help!!
Best ROM for Battery = Stock ROMs
Why don't people understand that Alpha and Beta ROMs are prone to bugs and battery drain?
I am seeing a similar thing on ICS 4.0.3
I tried to delete my battery cache on Teamhancksungs CM12 build, I ended going from about 20 hours to around 4-5, so be carefull of doing that,
And always wait at least 3 cycles and calibrate battery. Then you'll know If there's a drain.
I did one time full battery discharge, then full charge, flashed onecosmics latest ICS port, and here is how its goes so far:
By using wifi, calls, etc. but excluding gaming & listening to music.
Had the same problem, cant expect much more though.

That's a smartphone. What do you expect? I use my charger daily. It's more than great to use It for 2 days.

[Q] battery improvements with official GB?

I am wondering if anybody has noticed a real battery improvement after updating the official GB ROM? Probably it would be better if you could add some comparison numbers
i have the same question!!! and some people say that batery would be calibrate after some chargers... i haven't seen any improvment yet
Hopefully more people take a look at this thread and share their experience.
My own experience: NovaROM and GB V20N are the same, maximum battery I got for my daily usage are 1 day & ~10 hours. With CM7 I got max ~25 hours.
That's from my point of view, don't know other user experience, because it must have difference app installed and also difference daily usage..
Hi I am on V20B official GB for OB. Now I am getting 2 days Battery life for normal Usages (gprs, 20 calls, 50 sms, 30 Min. browsing).
Pre. in v10d (Froyo) OB is consuming 10-20% battery without any use in night. But Now it is 2-4% for whole night.
Easy trick is to disable WIFI, data and only enable 2G. U can also turn down the brightness of the screen, uninstall unused apps, sometimes reboot the phone when it's plugged to cable, cause to me it seems to clear some apps, that are running in the background and i dont wanna close em manually and screen-time-out time is also an important fact to look at.
Previously i have v10d, it last about 12-15 hours.
I updated to Zeus ROM and i have 18-22 hours now.
I turn on wifi 3-5 hours i think. To browse, check mails, etc. I also have have about 10+ calls and 10-15 SMS a day.
I used CM 7, Temasek Kang, V20N but until now when i´m using Zeus v2.1 i have about 36 hours, because i did battery calibration. It´s helpfull after flashing a new Rom. And of course wifi was turn on about 3 hours + 3g about 1 hour.

Extreme Battery Drain

Hello, it's me again with problems. I have an extremely battery drain, even Juice Deffender can't handle on this. When I put the phone on charger, when he turns off after 0 % battery status, indicator shows me 50 % min after only few seconds on charger, and it's fully charged for half an hour maybe. When I turn on 3g and connect to Net, from 100 % to 0% is ONLY 15 min ?!?! I have cm-7-20120812-NIGHTLY-cooper ROM, but when I had offical 2.3.6, it was the same problem. Can I check some-how what is the problem- software, calibration or battery? I did a few calibration without any success. I'm really sorry on my very bad English. I will be grateful if anybody can redirect me on the right topic. Thanks in advance
3G eats a huge battery. I would not expect anything nice from it. But seems that your problem is a bit more problematic. How long do you have your phone?
Make sure you are charging your phone until its actually full not just when it says 100% look here for more details:

Did you try wiping battery stats in CWM or recalibrating it?
I've tried wipe stats with Battery Calibration, and with CWM wipe battery stats. I've tried different ROMs, DroidACE, official 2.3.6, cooper nightly ROMs, and all of them have same problem. I've noticed that the battery is a little thicker in the middle, before it was flat, and now is a little convex in the middle. I've tried also discharging and charging for a 5+ hours, didn't help me. literally be emptied by 20 min of Use

Sheesh guys. Battery Calibration doesn't affect battery life on your phone. It's just for accurate readings -_-"

Yeah man, Ive got the same problem.
If I charge it for about 3-4 Hours, I get a max of 5 Mins or so, with Wi-fi on.
When the Battery is about 10%, and I put it to charge, It immediately says 99% charged.
I've changed 2 roms, and still no effect, infact, its got worse.
Even Juice defender (even the ultimate version) dosent work, Not even Underclocking.
I saw the battery recalibrating thing and Ive wiped the battery stats, still no use.
I think there's a problem with the battery itself?
Im just sick of it.

Anyways, thanks man
If it's deformed, then your battery's life is over, that's it, get a new one.
You can try the freezing method to try and squeeze it for a bit of juice:
Charge to 100, Plastic wrap, in the freezer for maybe an hr (not too long), take it out, put it in your phone, charge it till it says fully charged, turn on your phone and check duration.
seems a deep sleep issue
Just abuy a new battery. I suggest a Anker branded one. Search a battery review topic at the Accesoires section. If you buy the Anker 1400mAh, your battery life will be even better than the original battery life. And Anker is trusted and cheap.

Since we're in 2012, I'm guessing it's a lithium ion battery.
Just plug it in and wait for some time (~15 minutes)after it reaching 100% to actually fully charge.
It would be best if you don't let it discharge below 20-30%.
Read more about lithium ion batteries by searching around the web for more info.

Was there a problem in the battery?
or, is something wrong in the phone?
there was a problem in battery, I bought a new battery, not Samsung, but also has 1350 mAh capacity, and it's 2nd time on charging, life is about 2 days of using, average 2-3 h 3g, and playing games, half hour voice and maybe 30 sms and mails, and for me this is a very huge improvement from 15 minutes before death battery.

Hmm, I did get slight improvement once i calibrated using another app.
But Im still getting a new battery
anyone knows why phone's display blink-up randomly? I saw that earlier, and I thought that was because of battery, but obviously, wasn't that. It's totaly random. And, I have another question, I've played with *#*#4636#*#* code, and sometimes phone can't receive or sent messages, except when preffered network type is GSM only and only after turning on and again off airplane mode. I have cooper cm 7.2 newest nightly ROM.

I had the same issue when I was using Elegant white by TAZ.
But Then I flashed a fix for it.
I suggest you should too get in touch with the dev.
But first, flash the rom again.

Thank you. Anyone knows where is the official topic for cm 7.2 nightly cooper? I found one topic in development section, but at the end of it someone wrote that topic is closed on developer's request. And where I can find changelog? I saw that there is newest nightly update from 19.8. http://download.cyanogenmod.com/?device=cooper
