[Q] Increase battery performance on Optimus x2

What is the best way to increase battery life on LG P999 Optimus X2?
Model: LG-P999 (Wind Mobile Canada)
OS: 2.2.2
Baseband: M6600A-SCAUTNZ-2.0.9.972T 1
[JUL 15 2011 10:00:00]
MP:TRULGLE_08.09.02R_MDM
Kernel: 2.6.32.9
Build: FRG83G
Software: LG-P999-AWC-V11h
Rooted: YES
Or would it better to put on a custom ROM instead that looks identical to the current stock?
I am not sure if this battery issue maybe due to the fact that I had O2X installed and then flashed it back to a backup copy I got from XDA-Dev but ones again not sure, it just seems battery now die's even faster then it used to with STOCK firmware without CM7 and O2X

Isnt that a g2x
http://forum.xda-developers.com/forumdisplay.php?f=1114
Otherwise I am happy with battery performance on Miui 1.11.25

I don't think so since its 2x is also P-999 unless it P-900. I heard Miui lacks some features and has problems dealing with stuff like MMS and others.
Would still love to reduce battery usage

Your phone is a g2x as its real name p999 proves it. Canadian providers falsely renamed it o2x.
O2x is p990. Nobody had the unique solution for battery. Too many factors.
As hardware, kernels and ROM are different, you should ask on g2x threads.

LG optimus X2 (P990) battery charging
Hey guys I bought my LG OX2 a month ago, and I do have a few phone/tablet chargers, one for my blackberry, one for the kindle fire and one for my LG-OX2. All of them have the same connection, so I thought i will keep my Lg charger at my office and use my kindle charger to charged my OX2 at home. I was using CM7 and i had no problems at all. A few days ago I flash it with NOVA HD+ and first couple days charging over night with the kindle charger had no problems but after that in the mornings my phone is completely shut off. So i have to take the battery off and back on to start it. This morning i notice it again but the battery was empty, so i connected again and after 20 min was doing fine but after 40 min the phone shut off again completely and was very very hot specially where the camere area is. Anyone knows if is because I'm not using the original charger or is the new rom NOVA HD+.
Any suggestions?
Thanks!

It shouldn't be the charger. All micro USB ports should have +5V on their power terminals (this is the USB voltage from your PC USB port).
EDIT: You can refer to this link
http://en.wikipedia.org/wiki/Usb#Power
EDIT number 2:
Unless, of course, your charger is defective.

Well yes you're right is not the charger. As i just connected to the lg charger and after 15 minutes i check the phone and was very hot and unable to turn it on. So I had taken the battery out to cool it off for a few minutes. What else could it be? I don't remember or changing or doing any tweaks.

I've seen a lot of complaining about exactly the same thing as you. I would try flashing temasek's latest kang and vadonka's latest kernel, which should be among the most stable ROM/kernel combination out there for O2X.
If you still get SOD (sleep of death) while charging the phone, it could be a defective battery, or a defective phone altogether. In which case I would suggest that you try to flash your phone back to factory settings and ask for a replacement.

I appreciate your input. At this moment is charging ok, no heating, no SOD (SOD hehehe funny). I have download it the latest NOVA HD+ and i think i gonna give it another try. If continues heating up while charging I will take your advice (although flashing temasek's latest kang and vadonka's latest kernel sounds more complex work for a newbie like me. Do you know if there's any tutorial to follow?)
I will post the result after the update.

It's very simple. How do you flash NOVA? Isn't it through CWM? Flashing temasek's kang and vadonka's kernel is exactly through the same method.
EDIT: Good luck
EDIT #2: Lol @ SOD

The first time I flash NOVA was thru rom manager. Last night i flash the latest NOVA (which seems to be a new version almost everyday) http://hei1125.hopto.org/Nova HD (CM9)/
And I did it thru recovery mode, this time I wiped cache and delvik. And seems like everything is working normal. I did charge it over night, no heating, no SOD, is working flawless. Camera, clock, email working fine, browser now works on landscape which before wasn't. Video still not working. (ooopsss as i'm testing the video the phone kinda crashed and i had to remove battery to reboot it).
But so far so good... I hope stays 'stable'.

Glad it's working better for you now
How do you test the video? I can record video and play it back without any problems. I can also play youtube videos. Never had problems.

I open muy camera app and click on record video and the apps shuts down with a message "sorry the camera was closed because of error".
I can play videos on YouTube without problem.
So for a couple times the phone has gone frozen and the only way to reboot its by removing the battery.

I have found the solution to the poor battery life on the wind mobile G2X.
The culprit is the stock battery. Get rid of it. I was getting less than 3-4 hours battery life from mine with everything I could possibly do to reduce the battery load.
I purchased an extended battery off e-bay. It is the identical physical size, but has 1950mAh.
I now get well over 24 hours battery life. Over 10 hours playing games/browsing internet.

A lot of discussions about aftermarket batteries in many forums (here i guess, too).
If there is a print on the battery like 2200mAh, actually it doenst mean anything. You can be lucky to get a higher capacity or maybe get one with less. Dont believe in the sellers claim

battery performance
in the market you will find same aplications like battery maintenance-very good for battery life

Toggle to 2g when not needed...

witch ics rom??

any suggestions on a good ics rom for the touchpad other then the CM9 nightly?what do u suggest?
thanx

I've been using AOKP myself with no real complaints. It has a lot of extra adjustments in the settings panel as well. I've never used the nightly roms personally but from what others have said there's the chance of a bum rom once in a while. Cyanogen seems to be the most stable, but plain. Classicnerd roms are smooth with nice graphics, but for me it was wifi issue city. Their first run with evervolv was very stable but was before the hardware acceleration and HD youtube was corrected. Cherrykang gave me sleep of deaths but I believe the issue has since been fixed. I personally didn't like the solution as it ate up battery while sleeping heavier than I cared for. Never tried the cornerstone rom. And the bricked rom didn't do anything special for me.
I've also been using the upgraded driver pack for the video as well as the wifi with this AOKP rom and its super stable. Try em out. You'll find something you like.

What's the upgraded pack?

If you look through the rootzwiki forums for the touchpad you will find them. I was browsing and found the alternate wifi and video drivers both in flashable zip files.

I flashed the alpha2 and the improvement pack, things look good at moment . If only I could reduce the battery usage on standby would be great .

I recommend the latest nightlies, it has a few decent fixes plus the home screen grid is better on different dpi settings.
Also, you can reduce standby drain by changing your wifi setting to "on when charging" so your device will sleep.

What CM9 for the Optimus 2x?

Hi, I'm new here... I've tried Nova HD and Owain's Kang Rom... Now I see the " [CM9][SkankWich] NekkidKanging!"... Bugs are the same? Opinions? I want video encoding/decoding for our Optimus 2x! And Hw acceleration! Please CM, help us!

I've just tried the NekkidKanging!... It's more smooth than the other, but... There isn't a BaseBand??? It's possible? Restored Cm7!!!

If you would use 2 minutes of your life to search then you would find that it is not devs fault, it is partly LG and partly Nvidia's fault.

Yeah, you're right... I know that if Nvidia releases nothing is very difficult for the developers make a Rom with H/w accelerration and so on...

Not possible.
Stick with cm7 for now.

Actually the latest Owains is pretty stable - it only crashed once today (compared to once every 2 hours on the last build, and once every 5 mins last time i tried NovaHD)
Iron Kernal bricked my phone though, so gone back to stock kernal

Bricked your phone? Sir, Optimus 2x is very hard to brick i'm using XXMrHyde's RC1-10 with latest ironkrnL w/32mb RamHack (no other flag added) and it's running like a charm :good: ...I just suggest you to tried other Kernel like Jarvis, HP SuperSonic or Nova...give us feedback.

CM9 (ICS) and Videos
Guys,
i know NVidia and LG are *****$&#@(@(*@#(&*@# and they didn't release Tegra2 drivers for ICS, BUT, I'd like to you know if ICS rom for LG O2X runs videos on MX Player in SW (Software Acceleration) mode? And if it will work the HDMI output?
Many thanks!

Yes, I'm on latest XXMrHyde's RC1-10, and it runs videos very well on MX Video (both H/W and S/W mode)...the HDMI output is working like a charm too :good:

I'm using Nova HD, and it's really great. BUT, I'm experiencing very slow wi-fi on it.

I have nova HD as well and my Wi-Fi is working alright. Just tested now. My connection is 10mbit, and I'm 10 meters away from the router, which is not a good one.
The test screenshot is attached.
I don't know if wrong RIL can influence this, I think RIL only influences communication between the caller app and hardware, but, check for the "get RIL" app on play store. Worth a try!

i just switch to Owain today, despite the fact that the ROM failed to start at the first time everything seems to be working normally.
The only bug is when you run app that requires HW accel. like Chrome browser (Always get a forced close).

LG 4X brightness problem?

Hello, I am new here and just came into this forum to ask about a problem that has been bothering me since I updated to JB.
I have a rooted and unlocked bootloader LG 4X with android version 4.1.2 EuroOpen.
And now the glamourous problem:
The phone will decrease brightness everytime it does something, relatively speaking, intensive. First to 87%, then to 70%. I did not notice this in ICS.
Just make a Benchmark, you will see it for yourself. You can also test this by playin angrybirds(Yes, even angrybirds is too much for the ridiculous thermal throttling)
I did try the Optimus G solution in this forum but I COULD NOT find a thermaled.conf to remove or change the said instances inside it.
I have no sullution currently and would like to know how to fix this or remove the annoying brightness decrease.
PS: To all others who will try tell me that a display brightness of 100% is unnecessary or "Who would use a phone on 100%?", your valuable suggestion is of no use in this thread so dont even bother to tell me that. I dont want your idea on what you think is right.

It's also happened im mine v10e and current v20a but no solution yet because it's display is best in class,very brighter,and also hd resolution that's why it's consuming more battery and heating
If our o4x is slightly warm it's reduced the brightness and also slow charging
Sent from my LG-P880 using xda premium

Hummm... I only use 100% brightness with Navigon and YouTube, never had that problem... Only time I had a heat issue the phone was under direct sunlight, once that it's black and got really hot, I didn't look for that as a problem.

[Discussion] - Best Custom Rom / Kernel

Hello Proud user of LG Optimus 4x HD,
Now that we have '' Unlocked Bootloader '' and our beloved phone is being looked after some '' Great Developers '' let's have a look at the ''Features, Functions and Disabilites'' about all this stuff being Developed around here. This thread is open to all who want to make suggestions or express his/her experience about any Particular Rom / Kernel.
So happy Discussing.
Have a nice Day/Evening.

I'm using the latest cm rom and change from time to time between the werewolf and the ph85 kernel. Everything works fine

I am using the latest official CM10.1 Nightly build and play around it for 3 days. It is really great. Compare it with Stock LG 20B JB. I found
The pros-
1, The speed and response of UI, open up apps, web browsing and etc. improved a lot!!!
2, Less heat is generated
3, A lot better battery life.
4, A lot more control on everything.
5, Officially support FB home and it runs perfectly (You can even download it from the Play store)
6, seems it has better multi-tasking, at least it won't kill too many of the background apps (I have VLC direct running on background, I will always get killed on stock LG rom, but on CM10.1, it will still running while I am doing something else)
7, Better and more pretty UI.
The cons-
1, MHL output is not working correctly. (and it seems it will never work)
2, No custom ringer and notification sound.
3, All volume seems less loud than the stock
4, Media won't scan again while you unplug and plug the SD card back on.
5, Camera has less control and lower performance (HDR run slower that it really wait and take 3 slow shot to compose, no way to shut down the shutter sound, no ISO control and only +/-1 exposure control)
6, Too many option and control on setting, you might not have an idea what it really do....(maybe it is a pros for some ppls, haha)
It is just my opinion during these 3 days. Maybe some of them is just a bug or I just too new to this. Hope you guys don't mind. Even there is a lot of Cons, I think this ROM is very nice. Thanks. =)

Well I'm currently in the process of reverting to v10a. Call me crazy but if you're a gamer it's the fastest rom with 99% of games working great. Since then LG became obsessed with overheating and slowly degraded its performance. Now that I'm unlocked I'm going to see if it's possible to use proper clockworkmod on this rom, if it works maybe someone can port some custom kernel features. JB and cm10.1 are still great though and I plan to continue experimenting with them as more stuff is developed
Sent from my rooted P880

I have also switched a lot in this last month or so but just in between Stock, CM10,1 and Werewolf Rom.
1. For me stock has the best battery results almost used phone for 40 hours or so still with some battery left and had absolute no problems at all with the baseband issue ( I hope xtribas and others who do have it get over it as soon as possible with the help of good development).
2. CM10.1 is great work and a build of devotion from its developers almost everyday comes a new nightly with some features and tweaks. Runs very smooth and till now have had not many bugs I would say some problem with baseband wakelocks here but not in Stock which I cannot explain why.
3. Werewolf's Rom one of my fellow Countrymen is Fantastic I really appreciate his work, time and efforts. It's an awsome Rom fast, stable almost reliable like stock. It will be best Rom after Stock I guess.
I am not a Gamer so sorry to all Gamers I don't know how is the Gaming Life on this Phone (with all due respect to @non4 and others, I hope you guys get best out of this phone with the help of our Clever Developing Team.) In between I do play games but on my Laptop ( Acer Aspire V3-771G, intel i7-3610QM 2,3 GHz, 16GB RAM, 1,2 TB HDD, NVIDIA Geforce GT 650M )
Happy Discussion Guys

I'm using CM and change kernel from time to time between the werewolf and iodak.

Update: flashing clockworkmod on ICS gives the notorious security error, for it to work the ROM would have to be repacked to a flashable format like zaiben. And the eternity project kernel just got updated, based on feedback I may have to go back to JB already

After next time you revert to v10a (you seem to switch back and forth a lot ), would you mind packing up and uploading the files in /system/lib? I need them, but really would like to avoid having to flash back to v10a/h at the moment. It seems that LG's ICS builds are currently the only builds with properly working MHL and it is likely it has to do with the included tegra libraries.
I am even more interested in these files for v10h (although the relevant files may be the same), if anyone has easy access to them.

Hi there @non4 can you please explain some main differences between some of the Roms and Kernels you have tried so far, which is good and in which way like battery life, usage, and which is not so good and needs to be looked at? I ask you because I think you have switched around a lot (sorry if I am wrong) and have tested directly from some of the Great Develeopers around.
Just a small submission of your experience would be enough
Thanks

v10a stock: pure speed, awful battery
v20a stock: Better than v10h, but not as fast as v10a
v20a with iodak kernel: Good battery, close to v10a performance
v20a with kholks kernel: Fastest experience but currently too buggy
CM10.1: Faster in some games, but slower in others, battery OK and some nice features
CM10.1 with werewolf kernel: Solves some of the lags at cost of battery
PACMAN: Not a gamers ROM but fun to play around wit
ZAIBEN: Just like stock without the bloat
That enough??

Have you tried the latest CM10.1 nightly? I just flashed it last night and I had no issues with Deep Sleep, Runs very Smooth and Battery Life is Good. Last night I unpluged it at round about 10:30 PM and today Morning at 9 I just lost 2% of battery so I think its not bad 0.2% overnight.
I guess I will try this:
v20a with iodak kernel: Good battery, close to v10a performance
and I am gonna try
Iodaks Kernel with CM10.1
and lets see what comes out. I have a long weekend to play with because Monday is Holiday here in Germany

When I see some optimization to the I/O speed which will hopefully fix the remaining stutters then I will try, I CBA with moving my stuff to the right folders and restoring all my apps . Try its a good combo! Nice core usage and performs like kholks old 3.1.10 alpha

Hey Thanks for this Summary... I was waiting for something like this to decide if I go into CM10.1 or Stay in Stock with a Different Kernel :good:

I think best kernel for now is the stock kernel because the custom aren't ready 100%

I have used nightly and iodak's combination for couple of weeks and I am very happy with the using experience. Battery life is much better than stock and gaming is no laggish. Currently I am using Arararagi's unoffical version so I can still use LG's quicknote and Memo which are only things I want to use from the stock. thanks for Arararagi, make me love CM more. Werewolf kernel also great but I found iodak's better for me. Any way you won't regret to move to CM.

Official jb rom and ioak kernel at the moment. I like lg keyboard and the battery drain is less than cm.
