Finally one that understand something:( I'm selling mine 2 :mad: and whaiting for SGS 2
[LG Optimus 2x] StardustOne:
Okay my Optimus 2x is back at the store, but instead of money back I have been told that the phone has to be sent in for repairs. The repair would take 2 to 4 weeks. Bummer. LG can't fix this, they are only stealing my time. I am definitively not going to recommend this phone to anyone. This was my last LG phone, what a piece of junk.

I noticed if I turn mobile data off the battery lasts forever - Not exactly what you want to hear but it works.

Alternatively get something like juicedefender and have it do it automatically for you. The only crappy thing is that the baseband software isn't really stable enough for it to be turned on/off all the time so it will reboot here and there :)

Has the battery life increased on cm7? Anyone try yet? I'm also having an abnormally high battery drain, especially when doing anything that requires an internet connection.
[LG Optimus 2x] doncoop:
Same for me

I think its the cell standby. Compare it to other android phones. Samsung galaxy S a friend has is only something like 2-4%. Mine is always close to 50%!!!!!

Must be how or what it does with mobile data.
[LG Optimus 2x] wapz:
exactly. this must be the flaw.
[LG Optimus 2x] Pitasama:
Hi! I ve this phone too, and its also my first android. I dont really know what's happening nowadays, but 2 days ago I installed a new LG sw on it, but if i remember well just the the kernel changed. I ve charged the battery that night and this night too.... And when i got it down, the wifi was not working. I restarted the phone, and than the battery in max 1 min jumped down from 100% to 0%. What the heck is this? Before the sw it stayed till 2 days. I have not changed anything else so if you know something to solve this plz help!
[LG Optimus 2x] SweCrown:
I had enough. I really want to love this phone, but the battery drain makes it complety useless.

I'm gonna pick upp an galaxy s2 next week.
[LG Optimus 2x] Ekkis:
NO battery drain for me

O2X is my first android, after installing the latest CM nightly I had my battery 1 day, 15hours and then i'd still had 18% left. Im really happy with this Android-device ! :)
[LG Optimus 2x] Filnamos:
Just plugged it into recharge. 2 days 2 hours 13 mins @ 15%. Mild usage though. Some calls, some messages, some internet. some games. Still its pretty amazing imo. i can post screenshot if u want xD

with Blazing Dragon v1.0
[LG Optimus 2x] slartyxxx:
I bought a new G Optimus Speed (p990) 3 days ago and I have (had) the same problem with the draining battery. I recognized that heavy battery draining just after few mins after it finished full charge. Battery dropped so fast down i thought wtf is that. First I did was doing update via LG Software. After Update I have now:

Android Version: 2.2.2

Baseband: 1035.21_20110405

Kernel: 2.6.32.9-dirty

Build: FRG83G

LGE Version: LGP-990-V10c

But Battery drain was unchanged. :/

Next step I did was Rooting it. Yes. Worked. I first freezed all crap LGE **** i dont need. Around 40 apps o0 yes right... 40 apps hrhr. But nothing changed. I played a bit with SuperPower to save Battery but that did not work really. Some hours later installed SetCPU and set the max. cpu speed permanently to 921MHz. Its now running good it seems. But if too many other apps in background the idle use of battery goes up again. In idle i have between 1-2mA now (using Battery Monitor Widget), sometimes its abit higher coz i have running some background apps like facebook. My o2x now runs for many hours without battery drain in idle. I also tried to reactivate all frozen LGE apps. Seems this works too.. even with carhome and fsecure in background. But cpu still at 921mhz max.... SO THAT SEEM TO WORK! YAY! But no real solution to me to be honest. (Will do a longtime test with that setting today/tomorrow and post results later)

Any Ideas? I mean the speed is still very good and i can't feel a real difference between 921 and 1000mhz. But looks strange to me that 79mhz make such a big difference in battery consume!

What do you think?

Hope this battery "bug" can be fixed ASAP by LG! :(

Edit: Forget it. Battery drain is back, seems more a 3G and “wireless location“ problem. When activating both my battery is draining massively again. :(
[LG Optimus 2x] razvan354798:
I had battery drain when I bought the phone(v10c), and I change the Rom to V10b, and the drain stops. The Rom is to blame.
[LG Optimus 2x] slartyxxx:
hm i had v10b before and the same battery drain. in my case rom was not the fault. at the moment i hav the following solution to prevent battery from draining to fast (on rooted stock rom v10c with r2 performance patches)

- disabled/freezed all lg apps except few like flex and lg music

- disabled 3g (using 3g only when i need fast connection)

- disabled wireless location via network

- setcpu main profile max 816mhz, min 216mhz

- display manually

- apps running: gmail alarmdroid, watchdog lite, mysettings, setcpu, launcherpro, superuser, ti backup, touch keys light, lg music, elixir, battery monitor widget, es task killer

>>> result: battery drain around 2mA which is pretty - i keep on testing

i also if battery drain is higher then 2mA the reason is some background task which is eating battery but i havent found out which - if i do kill all apps using es task killer (except "kill all" excluded apps) the battery drain goes back to normal 2mA again...

any ideas how i can find out about the accountable app?
[LG Optimus 2x] Tr0gledyte:
Question.. does Tegra 2 underclock itself by default when it's hardly being used? Or do you need an app to do that? I downloaded CPU Master and it shows the phone running at 216Mhz at idle but I'm wondering if the app is doing that or if the CPU did that all along.
[LG Optimus 2x] ppsun:
Watchdog Task Manager Lite is great monitoring cpu usage of individual processes. Should be what you are looking for.
[LG Optimus 2x] BURNEE:
I'm pretty sure the cpu usage doesn't show which app is draining the battery(at least for me). I believe that it's something sensor related. Now I'm trying to kill apps one by one to find out which one is the hog.

Battery Widget Monitor was the thing killing my battery... After I start up a heavy usage app the consumption didn't seem to go down (after closing) - but when I removed BWM everything went back to normal.
[LG Optimus 2x] jfgraham93:
I've been using CM7 for about 2 weeks now and my battery life is horrid. It literally lasts about 2 hours. I even did a test and turned off all wireless communications right before I went to sleep only to find it dead in the morning. I wiped everything and am using CM7 #24 with the 0218 baseband. Any suggestions on how to fix this?
[LG Optimus 2x] heinzelrumpel:
Which battery monitor widget do you exactly mean. Name of the author?
[LG Optimus 2x] mikee2185:
I've done some testing. I have BlazingDragon, baseband 0405, no special apps that should cause troubles, only dropbox, tapatalk, facebook etc.

I always charged phone to 100% in the evening, and let it run on battery for 8 hours without any user interaction during night. I have usually strong signal (4 of 4 bars) when not holding it in my hand (no comment on that).

1. With flight mode on, the phone took just 3% in those 8h.

2. With GSM only on (Data services disabled, and set to 2G only), it took already 16%. That means, the GSM takes whole 13% of battery per 8h alone! Without single phone call.

3. With GSM and 3G, sync enabled for gmail account. it took exactly 30%. So, added to GSM alone, data without any direct user interaction drains another 14% of battery/8h.

Now my thought about this:

Computer part of the phone is evidently fine - with 3%/8h its 9%/day, thats 10 days of stand-by. Thats fine by me.

GSM module is what is causing all troubles, even without data. Don't tell me that it needs that much power, since its the only thing in this phone thats actually similar to all old-style cells that can live on one charge 2 weeks. While being connected to network, with battery of half capacity.

So, what do you think? I'll do some more testing to confirm my numbers.
[LG Optimus 2x] problacksmith_sofia:
Hi, I've had my Optimus 2x about 2 weeks now and also had the battery drain problem. There was one night I left the Wi-Fi on after a full charge, and when I got up the next morning, my phone was already dead. But since turning the Wi-Fi sleep policy to never, I'm getting pretty good battery performance now.
[LG Optimus 2x] slartyxxx:
Reading xda forums via xda app eats avg. 12-16% depending on display brightness which i hav in automode. I think thats petty much... :/

Btw. I was on Edge all the time, no wifi. And cpu was set to 800mhz max by pimpmycpu profile.

I've read about so many people who can use their battery 1-2 days. Mine is emtpy after 8-12hrs. So maybe my battery is not 100% intact? Also battery calibration or chaning to different roms or basebands did not help. :(
[LG Optimus 2x] mikee2185:
Try stock baseband with stock rom, no apps, just fully charge it and see how it goes. With data off, only gsm, it should take about 1-2 % at most in 8hrs on standby (without use). If it wont, consider rmi.

Ps: use ustock that comes with baseband, ideally for your region..
[LG Optimus 2x] heinzelrumpel:
In other words, don't dare to use your phone, just lay it down. Thats what it is build for, at least when talking of battery usage...
[LG Optimus 2x] mikee2185:
Keep your sarcastic mouth shut, thank you. I‘m trying to help him pin down the issue. And you need to measure battery life on stand by, to exclude all other factors.
[LG Optimus 2x] heinzelrumpel:
Believe me I won't. One thing about sarcasm is, that you need to understand it. Obviously you did't.
[LG Optimus 2x] Mjuksel:
overnight i get a drainage of about 2-5% in 8/9 hours..

also Edge takes a bit more juice then WIFI..

i charged my phone yesterday evening, it was done at about 10PM..

its 10AM now, and i have 98%, with a little usage (2 calls, 6 text messages and i used XDA on wifi for an hour)
[LG Optimus 2x] May-C:
My battery lasts 12 hours when Mobile Networking is enabled.

Now I turn it off and enable it when needed. It seems that this increased the lieftime. The phone is running for 27 hours now and I still have 54% battery :D

As I don't need syncing all the time this is a perfekt solution for me. Of course if you need your Mailbox etc. up to date this solution is useless... :rolleyes:
[LG Optimus 2x] abeeshek:
battery stats are good enough???

hi guys,

i am bit confused about my battery stats...

my battery shows more % over standby and idle time !!!

its supposed to be more % over screen and voice calls ri8???

just see the battery stat screen shot...

do let me know ur opinion,thanx :)
[LG Optimus 2x] mikee2185:
It look wierd on first glance, but its logical. 10h of stand by eats more then 2min call. With no use, stand by uses 100 % pwr, since its the only consumer. Depends how much % of battery power it actually uses. Hope i made myself clear :-)
[LG Optimus 2x] abeeshek:
hmmm....may be i am getting u a bit....

so shd i assume that theres nothing wrong with these stats,ehhh...
[LG Optimus 2x] mikee2185:
Unless the battery lasts less than a day without use, its prolly fine :)
[LG Optimus 2x] abeeshek:
okk :)

today the second day has ended since i fully charged my device and its still showin 26%

i hope everything is fine :)

thanx anyways...cheers !!!
[LG Optimus 2x] retareq:
I would like to share my findings with you guys. I've had my optimus 2x for about 2 weeks now. When I first got it the battery life was terrible. After tinkering here and there I found a good setup that works for me now. I was leaning towards CM7.1 but theres many battery life complains in the forums. Since my phone had crap battery anyways I figured I would try out what I can do without flashing a new ROM. The only reason for me to flash a new ROM is if I know for sure I can use the front facing camera for Google talk video.

1) Tried Full charge and full discharge till phone died and recharge. Still sucked.

2) Rooted and then used Antek App Manager to freeze all the LG crap and there were some from Fido as well I froze all of them. (didnt have money for titanium backup). Noticed slight improvement in battery then.

3) SetCPU. I think this is what made all the difference. There is only one profile for screen off set to 216-216. As soon as I set these values, when I leave my phone over night it doesn't die. In fact it actually eats only 2% battery over 8 hours.

4) BatteryCalibration app was used to fully charge and then reset the Battery stats file. After that I did a full discharge and killed my phone.

5) After full charge I started using Juice Defender to auto turn OFF the wifi and data on its own so I don't have to.

6) Switched phone to 2G mode because my last phone didn't have 3G and it worked perfectly in my area.

Currently phone has been up for 15hours 22m and I'm at 75% battery. So it is definitely possible to go 2-3 days with this phone if you are a light user like me. SetCPU made a huge difference for me. I am trying to find out of anyone has any "in call" or "battery <" or "time" profiles that work...

So now that I am getting decent battery life, I am not sure how much worse CM7.1 is terms of battery. I really want Google video talk on my phone >:(
[LG Optimus 2x] mags014:
I would agree with you about CM7 having some battery issues, but doing that above helped me with my CM7 and everything looks fine, battery and performance wise, I just got some problems with loading gapps but thats done and Gtalk works ok
[LG Optimus 2x] retareq:
I don't wan't to take the thread off topic but I REALLY want to know if you can video chat properly on gtalk on cm7.1 . I need it for calling people from work overseas. So battery life in Cm7 is similar to what I am getting? Then I guess I will try it out. I think cm7 has its own setcpu I just hope the settings are not vastly different.
[LG Optimus 2x] mags014:
Screen and 3G is the battery killer on CM7, you can set to auto brightness and toggle 2G/3G if needed. As for SetCPU, its your call.

OT, As for GTalk, yeah you can somehow start video chat but quality is too bad, you rather not use the program, you can do Skype and that's fixed already.
[LG Optimus 2x] retareq:
My skype only uses back camera. Cm7 skype has front ?
[LG Optimus 2x] hyyuga:
A few cycles of battery fullcharge and discharge improved my battery life in CM7 #177 very much
[LG Optimus 2x] enyx.es:
Hi all

I have a optimus 2x with CM 7.1 stable on it and i am really worried about battery life. After less than 4 hours battery goes 52% (it was fully charged) i use whatsapp only. It that normal???

Btw a sticky post about battery save tips woyld be excellent

Thanks in advance and sorry for my poor English
[LG Optimus 2x] retareq:
I don't have cm7 but using setcpu is what made most difference for me. I only had one profile before for screen off. I added two more profiles last night to lower the clock during use because I don't play any games or hardware intensive apps. Just phone, sms, email and music. So it MIGHT work out in my favour. I will report back here when I finish my tests.
[LG Optimus 2x] enyx.es:
Thks for the answer, looking foward your results.
[LG Optimus 2x] retareq:
The added profiles seem to have made a difference. Battery drain during use is lower. Before if I had a 5 minute sms conversation I would loose 5% and I would have to keep turning the screen ON and OFF. Now down to 2-3%.

These are all results on stock rom. Now theres threads everywhere talking about cm7 battery life. I wan't to test is myself but based on what I read somewhere in cm7 settings there is a cpu speed thing where you can set governor to powersave or something along those lines and get better battery.

Now how about you test that and let me know how it goes on cm7 so I can upgrade :)
[LG Optimus 2x] rasmusx:
Governors are not working thanks to tegra2 :(.

Sent from my LG-P990
[LG Optimus 2x] retareq:
I thought that was only on stock ? Cm7 as well ? Man, thats not cool. I just lost another reason to flash :mad:
[LG Optimus 2x] retareq:
I posted these on the other thread as well

Cm7.1 Stable with setcpu (powersave profile) + screen off and 800mhz max.

Stock rom setcpu gets no governor, with cm7 I saw 2 governors, powersave and performance.
[LG Optimus 2x] enyx.es:
I see them but i dont notice any changes with CM7 cpu governor
[LG Optimus 2x] retareq:
Yes in cm7 you can only see the governors and pick either powersave or performance. You need to install setcpu separately to access the cpu speeds after that. Cm7 will not show you anything in the settings because you need to change your kernel. Stock kernel no go for this.
[LG Optimus 2x] enyx.es:
i installed setcpu and the battery life change drastically,thanks!

[LG Optimus 2x] akira de aimbuster:
Maybe try to use autokiller app?
[LG Optimus 2x] hikkifans:
To improve the battery life

Hi all, this is my first post to the forum.

2X is also my first android device. I do have your problem that battery was drained pretty fast. Sometimes battery will run out in 4-5 hours normal use. When I say normal, that's 1.5 hour web surf (3G) + 1hour game playing + the rest doing nothing with it, just sitting in my pocket.

Later I scan through the post in this forum and find a temporary solution. To temporarily improve the battery life, I recommend you to use the JuicyDefender + Autokiller. I discovered that after I use it normally for 5 hours, I still have around 55% power left. The setting was like:

Default in JuicyDefender, and in Autokiller the setting is 150, 170, 180

This kind of give up multitasking but you got a extra smooth experience.

I know this is not a solution for long term, but at least you could have a machine with longer standby time!

By the way, I love my 2X, but I also experienced the shut down and restart problem.......

My 2X is rooted and FR3 Rom flashed. The quadrant mark was from 2827 to 2897

i have a HTC desire HD atm i looking to get a OX2 in next few days , the DHD had a sim problem at launch fixed by enabling usb debugging has any body tryed this yet?
[LG Optimus 2x] wapz:
have alwayd had this on and battery life sucks. just enabled GSM Auto (PRL) when dialling *#*#4636*#*# hoping this improves the huge battery drain by phone idle.
[LG Optimus 2x] reidar.ostrem:
Well I tried everything in regards to the battery drain. Last thing done is nvflash the 10b firmware. If this does not help the phone is being returned.

Edit:

Actually this seems to have worked on my O2x!

I have flashed every MCR up to now with no change in battery life. But today as I was "preparing" the device to go back (restoring stock rom, NVFlash 10b) i decided to see how it behaved with stock only and voila, the handset is down 3% over 4 hours with some use!!!

My handset came with 10a original firmware, but as said I have flashed MCR based on 10b so it should not differ. But anyhow, this may be a fix for the drainage problems on the O2x.. I'll see how it works out during the day and start installing my stuff.
[LG Optimus 2x] wapz:
Three things that helped my phone a lot after a day of testing

- Switch to GSM auto (PRL) when dialling *#*#4636#*#*

- Formatted my SD-card with sometimes didn't mount - suspect is was causing it to check it very often draining the battery

- Uncheck "Build caches as needed" in Launcherpro, which also massively increased smoothness in Launcherpro

Let me know if you guys have similar results.

[LG Optimus 2x] reidar.ostrem:
Well... As I was eager to install a custom rom again after the success with the NVFlash 10b I installed CWM and loaded up a selfmodded MCR Fr4. Installed all my usual stuff and put the phone on charging overnight again, and to my horror the same problem was present this morning.... Removed it from the charger and after one hour it was down to 80% (actually down to 90% the first 5 minutes).....

I've been at it all day to try to figure out what can cause this. I have NVFlashed 10b again and now changed my launcher (just in case) and not installed a custom rom. The phone has behaved normally today (been watching the running processes like a hawk). Maybe it would be useful to compare apps. (?)

Normally I have used the following (that runs background processes):

MCR FrX

- Truecaller

- Smooth Calendar

- Launcher PRO

- Email.APK (w/o security)

- Modded Maps.apk to enable navigation

- Auto Brightness

Today I have tried:

LG Stock Firmware 10b:

- Truecaller

- Smooth Calendar

- GO Launcher EX

- Deleted all of the LG junk

- No auto brightness

I think the problem lies in either the following:

- Launcher

- Physical charger ( if it's left over night charging) - When the phone has functioned normal I have charged it until its full, then removed it from charger. I will try a overnight charge with my HTC charger tonight.

- Modded Email.apk

- Modded Maps.apk

- Auto brightness control (as I think this is disabled in the original FW)

Any other suggestions ?? :)

Edit: Just for info: My HTC Charger delivers 5v@1A and the LG Charger delivers 4.8v@1A
