Been getting quite bad battery drain with custom roms so far, so i desided to go back to stuck, and the drain disappeared, and was running quite well. Couldn't help myself, after i read how fast ppl where experiencing fr7, so i had to install it :P so i'm looking forward to see, if the battery drain still persist.
[LG Optimus 2x] reidar.ostrem:
Just my experience also. I have just installed fr7 vanilla and will logg the battery tomorrow.. first impression does not indicate drain on fr7
[LG Optimus 2x] flyingdog77:
crossed fingers...
[LG Optimus 2x] :
I have the same problem, since i have flashed the stock rom from paul with nvflash.

I did not notice the switching from hspa to umts with the rom, that was installed when I recieve my device. This rom has also another kernel. Didnt know the exact version, but was a “dirty“ one.

So i think it isn t a baseband problem. It is a kernel problem

Since MoDaCo Fr7 connection is default on “3g“, only when data connection is used it switches to “H“. And after 20 sec of inactivity it switch back to “3g“.

Hope this will solve the problem with battery.
[LG Optimus 2x] reidar.ostrem:
Well cross them good.

As much as I like vanilla android my first findings are not good.

Off the charger today it drops from 100% to 95%. Charging has been done the same way as last night. The maximum mv was lower and trickle charging did not happen.. by writing this its down 5%! I have been able to reproduce this every time it have installed a custom rom..

My old lg in standby 5 freaking days thee strange part there is no sim insider
[LG Optimus 2x] kolaf:
I think this is just an android thing to save the battery. It drops very fast from 100% to 95% on stock ROM for me as well, and it did on my HTC desire too.
[LG Optimus 2x] reidar.ostrem:
Not experienced it on stock..
[LG Optimus 2x] flyingdog77:
wait for your comments

**** **** ****, I loaded the stock v10b and the flap UMTS-H for the mobile data is gone .. **** **** ... it is the kernel to trigger this
[LG Optimus 2x] wapz:
Report it back to Paul, we should have a closer look in the kernal to see what is the big difference causing this. Can somebody also try this using the .9 kernal?
[LG Optimus 2x] reidar.ostrem:
Told you :-)

Im at 57% now.. not looking good.
[LG Optimus 2x] Mittaa:
Hi all

Take at look at this finding from MoDaCo Poul.

This could explain the reason why some people have weird problems with UI, shutdowns, battery draining etc

http://android.modaco.com/content/lg-optimus-2x-2x-modaco-com/336435/lg-screwed-up-bad-heres-why-your-ui-is-jerky/
[LG Optimus 2x] reidar.ostrem:
I'm running Fr7 Vanilla today, and the drainage is far worse than on Stock 10b. I must say I have not experienced any shutdowns etc. on the phone either with MCR og Stock, just the drainage while using custom roms.
[LG Optimus 2x] clubtech:
It might be a placebo but i just flashed fr8 of MCK and the battery drain is much better (about 4%/hour with 3G on, push email, gmail, twitter and screen OFF, on fr7 it used to be 8% per hour under the same conditions).
[LG Optimus 2x] hbls00190:
As mentioned earlier, I upgraded to the latest baseband to see what effect that would give. After the upgrade, I waited 30 mins to let it settle, woke the phone up and then before my eyes it went from 3G to H then to E then back to H then back to 3G in the space of about 30 seconds!

So if anything, the latest baseband has given me a new letter ("E") which I hadn't seen before and presumably is another type my phone can cycle between and waste battery! :eek:

I want to upgrade to the latest FR8, but I've had some trouble on the phone today so I want to leave it a few days to settle (for whatever reason, when I turned on the phone, the /data partition was readonly and every app was failing constantly. Each time I went into cwm recovery and formatted the data or performed a full reset, the /data partition was still there untouched! The only way I found to fix it was to re-flash the baseband as that appears to forcibly blank the /data partition better. Grrr.)
[LG Optimus 2x] :
As I said in an older post my device has 2.6.32.9"dirty" kernel when it was shipped.

The first time I noticed 3G/H-jumping was when I installed Pauls ROM.

The nvflash backup-Rom contains a "normal" 2.6.32.9, I'm not sure if this is possible, but can someone upload 2.6.32.9"dirty" kernel, so we can test it, because I have no backup :(

Maybe it is a stuipid qustion, but is there some who has a constant "H" connection, because now even with stock rom my device goes to 3G after exactly 20 sec.
[LG Optimus 2x] DocRambone:
Lg 2x has really bad battery time, 30-40% less than my sgs... And sgs is not that good either.
[LG Optimus 2x] reidar.ostrem:
Hi!

I have constant H on my data connection. This is regulated by my provider. My provider in Norway (Telenor) has just changed their equipment (cell station) to Huawei equipment, before they had Ericsson. When the infrastructure was based on Ericsson the data connection was always 3G and when the phone was pushing data the data connection was upped to HSPA. But after the change in equipment the data connections are handled differently.
[LG Optimus 2x] reidar.ostrem:
I'm back on stock 10b again. After using Fr7 today the drainage of the battery was far worse then on Stock.
[LG Optimus 2x] wapz:
E is Edge. It is considered 2,5g and it works fine.
[LG Optimus 2x] clubtech:
Try fr8. it really solved the battery problem for me and i had the same problem as you (no drainage on stock 10b but horrible drain on fr1-fr7).
[LG Optimus 2x] reidar.ostrem:
Not sure that is want to :)

With stock 10b optdex and sql patch is have very good batt. Time and reaching almost 3k in quadrant
[LG Optimus 2x] gk141054:
Hi guys,

Just got my 2X yesterday, was really worried about the battery but have been pleasantly surprised.

After the initial charge, unplugged it at about 6:16pm last night.

With it being a new phone, had a hour long play on it including a game of Shrek Kart (with the long download for it the first time), flicked through menus, added widgets, installed apps.. (all over wi-fi). Also a couple of texts and a single 10 minute call.

Went to bed, think it was on 65% and switched data, wi-fi both off and put it in plane mode. Woke up and it was on 63%.

This morning I have sent a couple of texts, downloaded swype over data connection which too an age, wi-fi off since I left the house... phone is now showing 35% after almost 20 hours since unplugged.

I'm not too disappointed with that. If I can get 24 hours out of it between charges then its good for me.
[LG Optimus 2x] flyingdog77:
do you have any kind of new hardware rev? get info about baseband version, hardware rev and rom :D
[LG Optimus 2x] flyingdog77:
I am trying to compile a kernel from the origianl stock lg source in order to get something I can replace to roms .... here what I see...

The frequency scaling feature is compiled but the default is PERFORMANCE. The other governors, including POWERSAVE are not compiled in... While it's obvious we point on performances on this dual core device, the powersave mode could help to save battery when using the phone, broswing the internet and standard use which is not power demanding (phone not in idle)

I am recompiling the LG kernel enabling the POWERSAVE mode. SetCPU for android is an app that allows changing the governor on the fly from the OS. Before getting in trouble configuring the userspace for that, I am thinking to test the phone with a stock kernel in default POWERSAVE

I have the zImage, compiled fine, and booted fine up the LG progressbar. Something wrong happened with my ramdisk, I suppose.. working on it and hoping to get a bit of help from paul http://android.modaco.com/content/l.../335990/building-and-packing-a-custom-kernel/

[LG Optimus 2x] gk141054:
Apart from baseband, not sure what you are asking for. Hopefully it is as below:

Baseband is 1035.21_20110218

Kernel version is 2.6.32.9-dirty

Build is FRG83G

LGE Version LFP990-V10b

All of the above is stock, I have not rooted or changed anything on the phone except a few apps and widgets etc.

[LG Optimus 2x] goofy584:
Since using Modaco FR8 the battery live is MUCH better, more than 1 day.

[LG Optimus 2x] maedox:
The performance governor on Tegra2 doesn't do what you think it does. It actually behaves like 'On Demand'. Ref. @paulobrien.
[LG Optimus 2x] freakonaleash:
ok i solved the battery drain problem :)

for me the problem was noverka a mobile company that uses the same network of my company tim with continuous swap of network.

i simply deleted all apn except that of my mobile company.

now the battery on standby is ok!

I hope this information will be useful for you
[LG Optimus 2x] wapz:
removing all APNs except the home network is actually not a bad idea at all.
[LG Optimus 2x] gk141054:
Following my post above, and still on my first charge, i'm now on 1d, 3h and 8m with 12% remaining.
[LG Optimus 2x] 09papi:
Could any of you explain for us mortals how to delete all apns besides your home networks?
[LG Optimus 2x] freakonaleash:
i used a software called "apn italiani" on the market,but not sure if this works on other countries.

try APN Backup & Restore in the market.
[LG Optimus 2x] flyingdog77:
thank you man... and on top, if ref@paulobrien I can only lay on my knees :D

I did a bit of research, interesting how things are managed: http://www.nvidia.com/content/PDF/t...-Multi-core-CPUs-in-Mobile-Devices_Ver1.2.pdf
[LG Optimus 2x] ivaaaaaan:
i used fr8 and baseband 10b before

but the battery drain is terrible

when the battery was fully charged(100%), i unplugged, and it showed that only 97% battery left (Wifi on), which is far terrible than stock :(
[LG Optimus 2x] reidar.ostrem:
Ok, couldn't stay away.. Flashed MCR Fr10, have been hearing reports that the drain is gone on this build :) Also in the mood for adding OC Kernel .. but that won't help on the battery tho ... :-P Anyone having battery issues with MCR Fr10 (compared to Stock 10b) ?
[LG Optimus 2x] cmarsili:
MCR FR10 works like a charm

I installed MCR FR10 and not only fixed this battery draining problem but also got rid of the other bugs such as, loading time for adding widgets, random slow downs/hiccups during home screens switches and so on... Great Job by Modaco!! He should send the invoice to LG for fixing their f... ups:mad:. I was about to return the phone but thanks to him now it works as it was supposed to, like a dual core phone.
[LG Optimus 2x] reidar.ostrem:
I still have to see if the stby drain is there... but I see the 100% right down to 95% when taking it off the charger is still here.. I've tried all the battery tricks in the book (I think) .. Happy that you are satisfied with the phone, I would also return the device if Paul did not have one ... :)
[LG Optimus 2x] Dasmikko:
It still seems that the battery draining problem is still there :( not as bad but still there.
[LG Optimus 2x] reidar.ostrem:
Ahh.. not on mine.. had 63% when I went to bed and 60% when it woke up. But i did all the battery tricks in knew of yesterday.
[LG Optimus 2x] cmarsili:
True. Battery drain is not as bad, but I still see cell standby a bit too high. Hope some will find a perfect solution soon. Am sure is software.
[LG Optimus 2x] xXZaufiXx:
i'm also using MDC Fr10 (why is everybody writing MCR ??), also have the battery problem...even the handy standby is about 50% :(

when i look at the battery protokoll (*#*#4636#*#*) in networkuse the aplication '0' is on the top.. with a full bar.

really strange, what is the application "0" ??

greez xXZaufiXx
[LG Optimus 2x] DarthD:
MCR Modaco Custom Rom

MCK Modaco Custom Kernel

etc because that are the name's Paul uses :D
[LG Optimus 2x] qtekdude:
I bought myself a 2x yesterday. The first charge was done pre starting it, connected to my computer. After about 2 hours of use and a lot of downloading i was down to around 40%, it survived the night without charging, it was about 15% in the morning.

I connected it to my handsfree charger.. not the most powerful charger, after 1 hour it was 59%, but when I started using it with the charger connected it went down!

I have now turned of 3G, set facebook and twitter to 1 hour syncs. I also have turned of the location with wifi and also GPS. And I have removed the LG weather widget. Hocked it to my iphone charger and now after 2 1/2 hour on my desk not connected to the charger it is still 99%, was 100% when i disconnected the charger. I have not worked with the phone, but I have read some emails and checked some settings.

I have a new SIM from LUDO. could the drain also be connected to simcards? was a problem with old sims and battery drain earlier.
[LG Optimus 2x] reidar.ostrem:
What is MDC ?? :-D
[LG Optimus 2x] reidar.ostrem:
Just out of curiosity, what mV is representing 100% on your devices ??

I'm currently getting 4188mV as max.
[LG Optimus 2x] DarthD:
Strange its a 3,7 V Battery
[LG Optimus 2x] 09papi:
Im at 100% with 4158mV. Having horrible network jumps from "h" to 3g. No solution for this yet?
[LG Optimus 2x] reidar.ostrem:
I did pull it out and in the charger and couple of times and when it hit max mV in deleted my batt stats.. we'll see how it runs from now on.
[LG Optimus 2x] reidar.ostrem:
Are you sure it's not your provider that is causing the jumping? Does this not happen with another phone? I do not have this problem, neither with stock or mcr.
[LG Optimus 2x] qtekdude:
Hmm... 92% left after almost 9 hours.
[LG Optimus 2x] reidar.ostrem:
With the phone shut down :-D?
[LG Optimus 2x] bullyfrog:
I don't know if it's the custom rom.. but I do notice my phone can get hot even when I am not using it for no reason. (Those with overnight battery drains could have encountered this?) I'll need to investigate which process is causing this..cos (as as we all know) , heat is a bi-product from some process that was drawing loads of power from the battery..
[LG Optimus 2x] chong81:
That's normal. Voltages you see printed on rechargeable batteries not their maximum voltages - for Li-ion, the max. voltage at full charge is about 4.2V.
[LG Optimus 2x] dronarg:
Exactly the same here with stock rom.

The phone is idle in the pocket and begins to get hot while the battery drains. It seems to be the GSM
[LG Optimus 2x] Shaquiel Harris:
Are you guy's phones rooted? If so, it might be because the ROM your running's libs don't match the Radio you have installed. Was a major problem on the Vision and we had these same problems. (I know I did).
[LG Optimus 2x] wapz:
Interesting, how can we confirm this?
[LG Optimus 2x] qtekdude:
No, the phone have been on, I have synced about 50 songs on wifi from spotify, checked the TV program 3-4 times, some email reading.

I now have 71% after 20h 17m. But I have had a major drop this morning, almost stright down from 80-70% on 15 minutes.. did not use the phone in that time.

Stock phone.
[LG Optimus 2x] dronarg:
My phone is not rooted.

I unplugged it at 8:00 this mornig ans used it a few seconds browsing 3 web pages, about 2 minutes of surfing.

It is 10:30 now and the battery is already down to 85%

If I chek battery usage it says :

- GSM standby 50 %

- Inactive Phone 45%

- Screen 5%

I am in the center of Paris with very good 3g signal.
[LG Optimus 2x] DarthD:
Battery is better on fr10 but now a new bug. Cant charge 100% charging stops @98% already wiped battery stats used other charger what else can i do
[LG Optimus 2x] novackus:
Can any of you give a quick summary of everything that helps to improve the mobile standby drain on the LG P990? I am kind of unsure what steps to take after 17 pages of text (I'm running v10b stock, rooted).
[LG Optimus 2x] tonyschuite:
ok, i must be coming off as a bit noobish and i am new to android modding (quite some exp with iOS though), but hear me out.

i am on V10a firmware (netherlands T-Mobile) and have a battery that is draining insanely fast (about 6hrs on full charge, standby/mild usage).

I have the stock rom installed and no insane apps running. (some widgets, LPP and widgetlocker)

i read through a lot of the posts, including the thread about battery drainage. i also have my mobile connection switching between UMTS and GPRS every 20 seconds or so.

my questions:

since my FW is V10a and the LG servers only have V10a for netherlands, can i flash to V10b without bricking my phone?

if not? i have the same question as above ;) can you list the possible moves to fix this problem? i have read this all, but its giving me too many answers :P
[LG Optimus 2x] manciu:
Hi guys! I had two problems like somebody else here. The full charge % that don't go over 98% and th hi battery drain.

I think that I solved abnormal standby battery drain by flashing kholk's "EternityProject Kernel" and removing some widget like CPUNotify and Bookmarks of LauncherPro. Now standby battery drain is 2%/h with 3G connection always on.

Then I quote DarthD asking if somebodies knows why battery drop down already to 98% when the 2x is unpluged by the charger.

Thank you Paul and congratulations fore the rom.
[LG Optimus 2x] novackus:
I'm on T-Mobile Netherlands aswell, I have V10b installed (comes with the NVFlash package). No problems so far, just works the same, so no bricking and stuff.
[LG Optimus 2x] tonyschuite:
what about baseband?
[LG Optimus 2x] novackus:
I updated it to 03.15, works fine. :)
[LG Optimus 2x] DarthD:
Battery 100% now :)

What i did is:

Flashed a new rom today after work and charged it. Now 100% works fine

Fearrom atm with 20110223 baseband. How can i backup baseband before i flash newer version
[LG Optimus 2x] DarthD:
Strange 98% now still on charger
[LG Optimus 2x] dronarg:
In fact I finally rebooted the phone and the standby drain has gone.

It seems that at some point there is a bug that drains the battery.
[LG Optimus 2x] kolaf:
I found a widget called uptime widget. It can report both the uptime for the phone and wake time. The uptime is currently 17 hours and 22 minutes, while the wake time is 16 hours and 38 minutes. In other words, the phone is apparently awake most of the time which can account for the relatively high battery drain. Mine is usually between 30 and 70 milliamps while in standby, occasionally dropping down to the regular 5 milliamps.
[LG Optimus 2x] reidar.ostrem:
Can it report what is keeping the phone awake ? :-D

This is good news, as it proves it's a sw bug in the OS most probably as we all use different apps.
[LG Optimus 2x] SweCrown:
Hi Guys,

I'm comming from iPhone and the LG Optimus 2X is my first android phone so far. I am to suffering form massive battery drain when in standby. As all of you, radio is the battery eater. I live in Stockholm, Sweden, and do always have good reception. V10A is the LGE-version, baseband is 20110223. The phone is not rooted and runs with stock rom.

I did mail the LG Customer suppport in Sweden, this is what they said (orginial mess. in swedish below):

Hi,

We are aware that the battery life is bad for a starter. The phone will reach it's full capacity after 10-15 charges.

You could try to do a hard reset, just in case something's wrong with the software.

I'm sorry to say that we at the moment got no information when the 2.3 android release will be avalible. Our developers are always in work with tweaking battery life and performance, however we do not know what the android 2.3 update will do for the battery life on the LG Optimus 2x, although Google has promissed a boost in life.

Hej

Vi är medvetna att batteritiden är dålig i början. Telefonen når sin fulla batterikapacitet efter 10-15 uppladdningar.

Ni kan prova med att återställa mjukvaran på er telefon utifall att det skulle vara något strul med mjuikvaran.

Jag har tyvärr ingen information om när Android 2.3 kommer att släppas till denna mobil samt vad den kommer att göra för batteritiden. Android utvecklarna jobbar alltid på att förbättra batteri tiden och i Android 2.3 så kommer det en sådan uppdatering enligt Google.

[LG Optimus 2x] tonyschuite:
ok, i will try to upgrade the baseband as well...

however, after upgrading to V10b i gave it a full charge. as of this moment, my O2X is off charge 9hrs39mins and running at 60% :D

did some mild browsing, listening to music, some widgets running and widgetlocker / LPP (basically i put everything in the same state as with battery drainage). also i forgot to mention in my previous post that i have Juicedefender on agressive and Android assistant with auto boost turned on.

so far, i am pleased ;)
[LG Optimus 2x] dalgia:
Hey guys,

I charged my phone last night before going to bed, and decided to turn off the 3g, because it's constantly jumping from 3 to H. When I woke up after 8 hours the battery was on 99%.

Then I turned on the 3g and after 2 more hours of standby the battery is now down to 93%.

I have rooted the phone, but it still has the stock ROM. I am using the juice defender on aggressive.

Is 3% energy loss/hour normal on standby?
[LG Optimus 2x] doncoop:
I know it's hard to judge but in my office all my colleagues are saying that it is a really poor reception.

So when I get to work I switch to 2g network using the quick settings app I downloaded. then when at home I switch back to 3g.

Now on 22h since last unplug after light / medium usage.

36% left

Cell standby 50%

Phone idle 47%

Display 4% ( I have auto brightness on)

Don't know how this compares to others but I'm OK with this, a 4" display is never going to last 2/3 days in my book
[HTC Inspire 4G] Chowlz:
Is it just me, or is the camcorder in CM7 worse when recording? I feel as if there's more "blur" (ghosting I think it's called?) when playing back compared to a video that's been recorded on an HTC ROM. Since it's impossible to get the HTC camera/camcorder working in CM7, does anyone know of a good substitute for both (or at least the camcorder)?
[HTC Inspire 4G] gvsukids:
blurry video playback

Agreed, I have problems with my camcorder skipping frames on playback. quite a nuisance. dont have problems playing youtube videos though.

i'm using saga 1.1, but contemplating flashing a new rom and trying that.
[HTC Inspire 4G] djzikario:
They seem to be of different formats, cm7 runs on the mp4 format while the htc runs on the 3gp format, i did had many problems with this since video related apps didnt worked properly (like video chat apps) I hope there will be fixes/improvements coming!

[XPERIA X10 Q&A, Help & Troubleshooting] MrHassell:
While working on an Android app in Eclipse, I wanted to check on the groups for security and found the way to do this is as such;

xperia@xperia-devBox:~$ adb shell
$ su
# pm list permissions -s

My question is this affecting just me? Whenever this command is executed does it reboot all X10 devices?

Can anyone else please confirm that this command does not work on the X10 please?

This is part of the standard Android system and SE have modified the security quite heavily as most people are already aware.

The standard documentation at android.com makes it clear that I'm not issuing any illegal commands.

This only became needed to know when having to CHMOD / CHGRP on a file being moved from the sdcard to the system and then being executed, while building an APK installer for an X10 and developing on a live X10a with Eclipse.

Really appreciate any light you might have to shed on the matter or personal experiences with developing app's for the X10 and not having standard Android functionality work!

Best Regards,

MH

EDIT: Found that this also occurs on other devices. Anyone else got anything to say? Anything...
