[LG Optimus 2x] reidar.ostrem:
That's more normal battery usage!

I use the following:

- Push mail on 2 x exchange servers and 1 x Gmail

- WiFi Always on (off while screen off)

- Location Services

I use my phone at work alot, and my HTC Desire had approx. 40-50% left after a working day... The LG Optimus 2x is empty at 15:00 (even earlier some times).. There are definitely some of us that are having problems in regards to battery time.
[LG Optimus 2x] DarthD:
Apps i use:

whatsapp

Smoothcalander

Launcher pro plus

Androirc

Angry birds rio

Asphalt 6

google apps (stock)

battery had about 12-20 cycles already so thats not the problem. I suspect 10a but i dont see any strange running apps or processes.
[LG Optimus 2x] reidar.ostrem:
Well we have some apps in common, especially Launcher PRO Plus :)

I have this problem on all the MCR's too, and that's built on v10b.. so i don't think it's a issue just found in 10a.

This is so frustrating as it takes so long to work through the options....
[LG Optimus 2x] DarthD:
Started to test without launcher pro saturday (Uninstalled) With lg home battery still crap
[LG Optimus 2x] reidar.ostrem:
Ok, I did not manage to use the LG Launcher (too awful) .. I installed GO Launcher EX today instead.. Then we can assume that the problem is not LPP..

I really hope it's the charger ... It will take two nights to figure it out though.. :)
[LG Optimus 2x] DarthD:
i already tried 1 time with charging @PC and carcharger from HTC i didnt see any improvement
[LG Optimus 2x] reidar.ostrem:
Hmm.. ok.. Is this overnight charging or just until it's "full" ?

If your problem's like mine, I can almost guarantee that if you NVFlash 10b and charge till the handsets full you will get better battery time. I get the problem when i leave the phone overnight charging (at least with MCR roms) I have not tried overnight with Stock 10b yet.
[LG Optimus 2x] DarthD:
i charged untill full cant charge overnight in car because i dont sleep inside my car :D
[LG Optimus 2x] reidar.ostrem:
You dont ???? :) lol

Could you have a go flashing FW 10b with NVFlash to see if this helps you ?
[LG Optimus 2x] DarthD:
Cant do that atm i have some pc issues with the LG drivers the screwup my gamegear

gonna try it on my laptop which i get back from a friend this week (i hope)

in the meantime im waiting for LG to call me back (they promised) and if that goes well i hope they get me another phone without this problem
[LG Optimus 2x] DarthD:
Is there a way i can backup 10a first? In case of warrenty?
[LG Optimus 2x] reidar.ostrem:
Not that i know off. I was planning on using 10b as my warranty return firmware :) even tho my device was shipped with 10a. There are some 10a dumps on optimus2x.net but unsure how to make them flashable ..
[LG Optimus 2x] DarthD:
Did u update baseband? i didnt but am thinking about trying it
[LG Optimus 2x] reidar.ostrem:
Yes .. mine was shipped with 0223.. updated first day, no help on the batt issue
[LG Optimus 2x] flyingdog77:
my test are not going very well. I am kinda of desperate, using this very light rom. However, if you say so, I will try flashing 10b. I would like to upgrade baseband too... at this point better to try everything. could you please guide me on the article/link method you used to flash the baseband? I though that putting the phone in nvdia ark recovery and flashing via naflash would re-flash the baseband too... :(

I will use this method: H T T P ://android.modaco.com/content/lg-optimus-2x-2x-modaco-com/335474/25-mar-nvflash-stock-rom-release-v10b-dated-1300166062-15-03-2011
[LG Optimus 2x] flyingdog77:
done, reimaged v10b, upgraded the baseband to the latest version (according to the forum) .. sweating... now, reimaging with mcr image, cross finger and sleep during the night
[LG Optimus 2x] flyingdog77:
and now, I just baked a custom fw without all the LG crap and just the needful, more privileged google apps but selected the good lg stuff... my finger are still crossed!!
[LG Optimus 2x] firewolf001:
I found that the bundled weather app is battery eater!:mad:

You may try to kill that process or even freeze it to have a try!

Another battery consumption reason during standby I found is the external SD card, I have tried several times, when the phone auto restart itself, the external SD card cannot be mounted, under this situation, the battery drain is crazy! Almost 1% every 3 minutes...
[LG Optimus 2x] clubtech:
I can confirm that mcr is a battery drainer. Flashed yo stock 10b like you did and getting a much better battery life. Same apps installed on both.
[LG Optimus 2x] robertosandros:
I think your completely right about the bundled weather widget. I have the Optimus 2x's weather widget on my motorola milestone, and since I started using it battery drain was incredible. I've gotten rid of it now and battery drain is no more. Get rid of the widget off your homescreens and let me know how that goes.
[LG Optimus 2x] reidar.ostrem:
I have always removed all the lg. Ware.. and when my battery is draining there are no rouge processes..
[LG Optimus 2x] reidar.ostrem:
Be aware that it think its the mcr that are causing the drainage on some phones..
[LG Optimus 2x] poi2005:
I am using mcr, 80% left after 12 hours, with some browsing, facebook, downloaded some apps.

A night sleep of approx 7 hours, battery gone down by 2%~3%, but of course wifi and mobile data disable.

LG weather LG is there all the time(animation set to off though).
[LG Optimus 2x] DarthD:
Im sure MCR isnt the problem because i havent used it yet im still on non rooted stock

Cant prove it but i blame radio because thats the main user of battery in my case
[LG Optimus 2x] reidar.ostrem:
Hi!

I'm not saying that all phones is affected by the use of MCR.

In my case I have no problem with the battery when using 10b, but both times i've installed MCR the drainage is there. I'm in the process of finding out what is causing this...
[LG Optimus 2x] clubtech:
Same for me. unfortunately running MCR i see 8-9% drain per hour when the phone is idle.

On 10B stock with the same apps installed i see %4 per hour when the phone is idle.
[LG Optimus 2x] MeX_DK:
Mine seems to have some wierd standby drain, sometimes it can lie for hours and only lose 10% other times it drains close to half a battery in the matter of 1-2 hours >_<
[LG Optimus 2x] Golleman:
I experience the same drainage using mcr Fr4 (not in stock 10a). Lost about 30% in 2.5hrs after overnight charging and yet to figure out why. I've frozen most of the apps i suspect is causing the heavy radio usage (wich I believe is the actual drainer), and so far freezing lg email and disable lpp's "build caches as necessary" is what may make a difference.
[LG Optimus 2x] flyingdog77:
I tested several times stock and MCR firmware, I did not notice any difference. What's is a very interesting test is:

install battery monitor widget (the one with the white icon). This software while running can record the history of your battery consumption mv per mv .. you will see something like:

-2 mv

-4 mv

-2 mv (in idle)

-43 mv

-50 mv

etc etc...

I had awful results on my test before re-flashing everything, I had something like (-300mv, +450mv flapping up and down)

I still keep my finger crossed
[LG Optimus 2x] flyingdog77:
keep us updated
[LG Optimus 2x] flyingdog77:
to the whole thread: it looks proved that the LG date-clock widgets are a problem. Even if you remove them from your desktop, if you look carefully with a task manager that shows you backgroud services, they are stilll THERE... this is why I don't want to use the stock fw .. I believe for the ones using stock fw, the only solution is .. root + root explorer to uninstall it

I baked one ROM with the very important things from LG and a lot of the standard baseline apps from google *without the gingerbread keybord which crashes while editing settings
[LG Optimus 2x] reidar.ostrem:
Good to see others with the same problem, maybe we will then find a solution.. I can't have a phone i can't use custom roms on :)...
[LG Optimus 2x] reidar.ostrem:
The issue is that even with the same apps on both stock 10b and MCR the phone drains only on the MCR ROM it seems. I have changed some of my apps on Stock 10b to see, and i have no excessive drain now. I will revert back to my old apps to see if it drains on stock 10b (something i don't think will happen)
[LG Optimus 2x] reidar.ostrem:
As stated I always jank the LG stuff off /system/app.. so there will not be any trace of the LG Software... And even with stock 10b and all the LG software I have no excessive drainage.
[LG Optimus 2x] flyingdog77:
I trust you and I am getting confused. I had amazing battery performance this morning... everything was cool in idle... 1h ago I remembered of the 3G access point config... **** **** ****.. in the custom firmware I must set it manually and it was not.. soooo it had amazing battery performance WITHOUT 3G APN.. once I set it up.. the battery is going down fast again!! all the night I had wifi on but not 3g...

it looks there is the problem!! the 3g looks to be ON while the phone is idle.. I see it on the notification bar just before to slide after the idle

--- for the stock fw, which apk do you exactly remove from /systems/app? do you use root explorer?
[LG Optimus 2x] reidar.ostrem:
I use adb mostly, but works fine with root explorer.

There are so many that I remove, but i'll try to remember....

sns

cyon

lglauncher

preloaded app

app advisor

carhome

fsecure

lgemail

all the weather apks +++
[LG Optimus 2x] DarthD:
Just wondering if the new kernel would make a difference, i want my laptop with sdk etc back so i can give it a try
[LG Optimus 2x] flyingdog77:
I just heard, april 18 LG will release the 2.3 fw. I hope to see a lot of improvemement for the baseband... I am sure now, testing over and over again... the problem is the 3G. my battery drained down to 20%, then I disabled it and now it's lasting forever

so.. finally I believe the problem is that 3G networking does not go down while the phone is in idle, then "idle" spikes to 48%...

now, what's next? what we can do to set it off when phone is in idle properly?
[LG Optimus 2x] hbls00190:
My phone is using stock 10b - I haven't dared flash anything on it yet and I'm suffering bad battery (compared to my old htc hero which is currently being used more as I haven't had the number transferred over yet and has a smaller battery but still lasts longer). It may be possible that MCR makes things worse, but the stock isn't good either and until I stick on MCR, I can't comment further.

But I echo the comment earlier - it was losing at least 4% an hour (confirmed using batterymix) when I left it overnight with all the normal settings (e.g. mobile data enabled, wifi turned off). I then turned off mobile data and went to work. Came back 8 hours later and it lost only 2%.

The only difference was turning off mobile data. But it did make me think about something else I spotted earlier - the "H" icon did change regularly to the "G" icon and back again. I'm in an area of fairly good reception, so it shouldn't be swapping cells.

I think the phone is generally changing cells more than it should be and that's taking a lot more battery to do than if it stayed static.

I did try changing it to GSM (auto PRL) but that doesn't seem to make any (noticeable) difference.

So from my point of view, it looks to be the baseband that is inefficient (or at least the bit that is more inefficient to me). I'm on an old baseband so will try to upgrade to "20110315" to see if that improves things.

Just my 2p! HTH!
[LG Optimus 2x] flyingdog77:
YES YES YES.. finally I am happy that somebody confirms. I did a deep analysis of the consumption with and without the 3G (H) icon enabled.

I have the mobile repeater 250 mt way back of my apartment, full signal strengths.

I collected statistics using Battery Monitor Widget...

with 3g:

average consumption -40 mv or -80mv each sample

without 3g:

average -4mv with low of -2mv during the night

end of the story, during the night without 3g and WITH wifi enabled, my ap is far from the bed room, low signal, the battery usage graph was almost horizzontal... very nice

enabling the 3g the graph goes down like deep dive rolling caster...

it's definitely a problem on the baseband managing the radio, and justifies the 48% phone idle drain that we all see from the android stats. I flashed the latest, sorry to tell you that it is not solved!!

we must pool all together and escalate this to LG!!

grr so many issues to take screenshoots but I will do it!!
[LG Optimus 2x] Golleman:
I can confirm that. I'm in an area with poor 3G coverage (2G is fine) and with 3G on my battery was drained in about 4 hrs in standby, leaving the back of the phone actually hot! Now, in this area I always set the phone to "Use Only 2G Networks" and the battery time was really good (after mcr it's worse again though).

I'm on earlier baseband as well, so I'm interesed in your experience if you flash to the new one.
[LG Optimus 2x] reidar.ostrem:
I have no issue believing the stats you provide. But in my case I do have 3g enabled both on MCR and Stock and there is a huge difference between the roms. I have just installed BMW and will do stats with Stock 10b and MCR with all the same switches (3G, WiFi) on both..
[LG Optimus 2x] hbls00190:
After I did my post above, I plugged in the USB cable to give it a charge so I can do a baseband update and before my eyes, I saw the H change to G and a second later back to H. I quickly did "adb logcat -b radio" and could see this:

And then immediately beneath it:

So the baseband was connected to the same cell tower (35df25f=56488543) and then swapped to G and then immediately back to H.

The events show no change of tower in between - as soon as it displayed a message to the log saying it had finished reconnecting as G, the immediate next line was the change to H.

I then watched the radio events and could see it doing this regularly every few minutes. With all the registering and obtaining ip and dns information, no wonder that's taking a lot of battery.

Once it's charged up, I'll upgrade the baseband and see if that makes any difference.
[LG Optimus 2x] Falastine:
it's for sure the 3g without it my battery stays 4 days standby
[LG Optimus 2x] flyingdog77:
Yes.. 3g.. look at the graph, finally screenshooted!!!

here at the beginning without 3g setup, since ups I forgot it :) ... almost horizontal

where u see the big drop down was the moment I setup the 3g

then it gets moderated by GreenEnergy (which disable the 3d after 30 sec on idle)

the battery usage, -5mv is normal while I was playing around, downloading from the market you can see it spiking up.. most of the time during the night was at -2mv

and with 3g up IN IDLE, I was doing something else, the phone was sitting alone
[LG Optimus 2x] flyingdog77:
you are just awesome!!!!!!!!
[LG Optimus 2x] flyingdog77:
same story, here, I see the icon quickly flapping over 3g to H,

and here is the logs

I am wondering if it something network related!?!?
[LG Optimus 2x] Aaberg:
Not just 3g

Over the night, I set my phone to use 2g net only, with mobile data off and WiFi on, and it still show a massive amount of battery being used on the radio. I've now put it in airplane mode, and will see how it progresses during the rest of the night. I'll add the screenshots I've taken in 4 hours or so.
[LG Optimus 2x] reidar.ostrem:
I have enabled logging as you have, I will logg my batt usage today during work. Initinally I do not have the same findings as you. The first hour this morning screen on/off and som surfing i have -2 -3 mA usage in standby with 3G on (screen off) and Wifi on (Screen on). Will be interessting to see tonight.

And I actually have a friend who flashed MCR Stock edition last night and enabled logging to compare, not to say that he is having these problems but first indications shows high drainage.
[LG Optimus 2x] 09papi:
I do have the same problem as you guys. This needs to be fixed!
[LG Optimus 2x] kolaf:
I'm also dealing with these issues, and I would like to make the following observations. First, for the record, I am running a rooted, otherwise unmodified, V10a installation.

I have been monitoring the current draw of my phone, and while I sometimes see the expected numbers around 4-5 milliamperes in standby, it is usually much higher between 80 and 20. When looking at the current draw graph (from battery monitor widget) I noticed that the increased current draw is quite abrupt as expected, but when I put the phone into standby it slowly tapers off towards some relatively low value. So, it appears that lots of things get started when I turn on the screen and it takes a while for everything to settle down again afterwards.

I'm not sure if this is related in any way, it does not explain why it seldom goes as low as I am expecting, but at least it is one more data point :-)
[LG Optimus 2x] reidar.ostrem:
I concur with your observations.

I'm running monitor on both my LG and HTC Desire, and on the desire the mA is dropping instantly rather then going sloooooowly down.
[LG Optimus 2x] flyingdog77:
here is a way to fix the mode, HSPA or UMTS .. or GSM of course...

Go into the "Phone Dialer"

Enter "*#*#4636#*#*"

Select "Phone Info"

now you can see your nice phone swapping continuosly btw UMTS and HSPA, involving each time the full negotiation for networking with the AP.

I am close to a WCDMA HSPA cell, so I fixed the preferred network type to WCDMA.. it is not flapping anymore since 1h now
[LG Optimus 2x] flyingdog77:
by using software like JD you can switch mobile data off while in idle...

I am trying to figure out where the problems is actually triggering,

and looking for somebody who can help to understand more if this wrong behavior is triggered from the back of the baseband or it is localized at android level (android telephony service management / com.android.internal.telephony.gsm)
[LG Optimus 2x] flyingdog77:
yeahh I see, but those kind of things does not confirm the findings. I am wondering if I should go back to the old baseband fw or v10a version!??! :|

can you try to debug the radio via adb while the phone has mobile data on and post the file here??

adb logcat -b radio > logradio.txt

check if you have flapping UMTS to HSPA switch
[LG Optimus 2x] kolaf:
Here you are. This is with GSM/W CDMA auto, Wi-Fi connected.
[LG Optimus 2x] reidar.ostrem:
My device is not flapping between HSPA/UMTS.

I'm currently logging battery usage during my workday.

[LG Optimus 2x] reidar.ostrem:
What do you mean more on my phone ??

Are you satisfied with the batterytime i have or not ? :) In my opinion this is acceptable, but when I install a MCR rom the phone is empty 14:00-15:00..
[LG Optimus 2x] flyingdog77:
ohh yes I am.... I wish to have the same of you!

I am about to reimage the phone with the stock v10b via nvflash

I just spoke with LG support UK, you can wonder which type of experience I got .. a stupid girl support agent who doesn't really understood the hot topic and told me: "LG support officially consider these H-3G flaps as normal phone activity, we have test people who are currently testing new versions of baseband and fw but we are not giving them to you"
[LG Optimus 2x] DarthD:
Thats more then i can say about LG support in the Netherlands. They dont respond to mails and dont call me back like agreed on by phone because the supportpeople didnt even know about the 24h VIP service

Still have the drainer phone :S if LG doesnt respond by the end of the week im going for some harder action (laws in holland that protect customers are good)
[LG Optimus 2x] flyingdog77:
I should check how laws are here, I live in Belgium. The estore told me call lg, lg told me ask the store you are still covered by them. the store told me RMA. LG belgium told me.. we have no engineers here in BE. LG UK told me that they have knowledge but they can thelp me because I am out of UK...
[LG Optimus 2x] flyingdog77:
however, if the problem is not at radio level on the baseband (since reidar has no flaps and we probably use the same baseband), then the evil, the beast is here: http://android.git.kernel.org/?p=pl...b707a43b8fba361de321b84ec9a84eed0df3a;hb=HEAD
[LG Optimus 2x] reidar.ostrem:
Tell me about it! I talked to LG in Norway about the battery drainage and they told me "just give it a couple of weeks" what a load of crap!.. I'll post my battery usage in a new post..

My plan now is to flash the "new" bug fixxed MCR Fr7 and to another workday tomorrow with same logging... As my initial thoughts was that the MCR roms created the drain. Maybe the Fr7 is better, but I used Fr1-Fr6 with excessive batt. drain compared to this.
[LG Optimus 2x] kolaf:
My comment to these results is that they look very similar to what I am getting on my own 2x with stock rooted firmware. I seem to recall that you said you were happy with this, but this is significantly worse than what I have on my old desire, which usually was around 4 to 6 mA current draw whenever it was on standby.

I haven't installed the custom recovery yet, but the latest significant fix from Paul at Modaco has made me seriously consider doing it, especially if it fixes that reboot/freeze issues and the power drain issues everyone is experiencing (although that is perhaps too much to hope for).
