That's the way it behaves on my device too. I use to leave wifi on during the day (in my office and at home I have an AP available) and did not notice any battery drain. 3G drains more, in my experience....

Second only to screen with 24% on mine... It has been on all day but never that bad on MIUI v2 (CM7 base)

---------- Post added at 07:21 PM ---------- Previous post was at 07:20 PM ----------

Hmm. Maybe a baseband thing? I'm on old 0622 I think
[LG Optimus 2x] Topogigi:
SP3 will have higher OC for elite tegra chips for sure. Voltage regulator is certified @1400mv, so 1.6Ghz should be possible.

The "unnecessary" voltages are due to different voltages for different cores in stock tegra2_dvfs.c I amended that in SP2 kernel.
[LG Optimus 2x] demoniac51:
Thank you :), impeccable for test, i am very impatient.

Oki for the precision on the ""unnecessary"".

I would give my results with the sp3 ;).

Just a little problem "1/5" black screen at 1504mhz for wake up lockscreen.

[LG Optimus 2x] wujtruj:
What BB are Yoou using? Maybe this drain is related to BB...

I can't help You yet, because right now I'm downloading ROM.

One stupid question I have: should I install SP1 after flashing? Or only SP2?
[LG Optimus 2x] thewoZa:
Only SP2 needed. Patches are cumulative.

[LG Optimus 2x] FatherJony:
Nice one Topo :). I have a question about the ramhack though, i thought that the default ram allocated to the gpu was 128mb anyway, didn't CM7 allocate just 94mb to it (leaving 418 MB to the CPU)?
[LG Optimus 2x] stonebear:
I get 4200 on Quadrant at 1408 using SP2, maybe a difference in the kernels?

Although I get 8400 on Antutu at 1408 which seems consistent with your results.

[LG Optimus 2x] Rayman96:
Topogigi's, can you make a statement about hotplug governor?

Is it really that only one core is active ar programs just don't see second core running, because of something?

Setting taks for cores is made on low level so it isn't needed to be showed for apps, is it?

It think it might be second one.

[LG Optimus 2x] Rayman96:
Yes but it is always off, or I haven't gave it proper amount of tasks to run or it just can't activate second core.

Maybe delay time to run second core under running big tasks is long so we think it can't be activated.

[LG Optimus 2x] kingvortex:
What are you basing this on? Maybe I don't understand what you're saying, but if I look in the CPU section in System Tuner, I can see the second core turning on and off when I'm using the hotplug governor.
[LG Optimus 2x] solrakk6:
alll nice and working here. but when i try charge with my phone logoff he not charge and show me a yellow image carrefull i try calibrate but nothing happen
[LG Optimus 2x] maharu567:
Thanks a lot. This combination of rom with this kernel is far away the best combo i ever had. Thanks topo...
[LG Optimus 2x] Rayman96:
No i see you are absolutely right.

I used mini cpu monitor and it have a bug with hotplug probably. I have just installed system tuner and and cpu freqs are really changing.

So that's what i though, but my monitor program has bug :DD
[LG Optimus 2x] cl06:
What about bluetooth? is it working normal? I couldn't find any device! even my PC!
[LG Optimus 2x] Topogigi:
The governor raises the cpu frequency when the cpu load increases. The apps running at the OS level cannot influence that. So, the second core kicks in when the governor senses an increase in the cpu load over a certain limit.
[LG Optimus 2x] chaozbr:
Hi, I read all the pages, and don't find answers for two questions, so I'm putting the questions here.

1) We have to do anything for ZRAM to work, or it works out-of-the-box?

2) Which BB do you recommend to use with this ROM?

Thanks for your great work here!
[LG Optimus 2x] Topogigi:
1) zram already included and functional

2) the baseband that came with the 28g leak
[LG Optimus 2x] bexwhitt:
In my testing bluetooth works very well

On my MW600 there are no random disconnects and the call quality is better than on CM10

My macbook connected right away and sent a file no problems

Remember you have to go into the bluetooth settings and make the phone visible before your computer can see it.
[LG Optimus 2x] eraldo:
Can someone make a YouTube video of this ROM in action I want to compare the speed between it and cm10 so I can finally decide to switch, so tired of the bsod and poor battery.
[LG Optimus 2x] demoniac51:
@stonebear : On quadrant my fps block at 58 for 1504Mhz, score : total->3547 (cpu->7143, mem->3574, i/o->4106, 2d->485, 3d->2427). And you ?

On antutu new best score at 1504Mhz : 8903 (cpu 3955, gpu 2693, ram 1360, i/o 895). I have move before libGLES_android.so, i delete the first line of egl.cfg and i check option develloper forcing GPU.
[LG Optimus 2x] scaromouche:
Mine;

Antutu v3 score is 8621 @ 1408MHz (1296/2157/1542/506/2229/550/150/191)
[LG Optimus 2x] stonebear:
I don't change governor or anything, I just overclocked to 1408, our Antutu scores are consistent but your Quadrant score seems low, I get that score at 1.2 on Quadrant.

These scores all seem way too high anyway, try running CF-bench and see a less exciting score, lol.
[LG Optimus 2x] demoniac51:
cf-bench at 1504Mhz : (12987,4066,7634), very correct lol
[LG Optimus 2x] stonebear:
Yea, these Antutu and Quadrant scores are similar to what I get on my Nexus 7 at 1.3Ghz with a custom ROM and kernel.

Now this is a good ROM and kernel that Topo has given us but I don't believe it has turned my dual core phone into something that compares with my Nexus 7. :)

Although tbh the CF bench scores should be higher imo, lol. The phone feels faster than that.
[LG Optimus 2x] demoniac51:
i use not again the rom of topo but the rom v28g of stefan. With topo i think that my score would be better.

Have you test with the tweak : move before libGLES_android.so, delete the first line of egl.cfg and check option develloper forcing GPU ?
[LG Optimus 2x] FatherJony:
Lol, are they doing this on purpose? What could possibly use so much vram? Certainly not regular applications, you can hardly run more than 2 at the same time when the available ram is so little :P .
[LG Optimus 2x] stonebear:
"move before libGLES_android.so, delete the first line of egl.cfg"

Not done that, what is it for?

I have ticked "force GPU rendering" in developer options yea. I don't know if it makes any difference but I ticked it anyway. :)
[LG Optimus 2x] demoniac51:
the tweak = best performance. You can see in google for explication :)
[LG Optimus 2x] stonebear:

[LG Optimus 2x] asrhael:
Hi friends, I want to install the SP2 version of the kernel that allow the OC, but I dont have any custom recovery instaled! (CWM can't be installed on my P990...an error that isn't a supported devices appear) because I have the nvflash version (so, my previus CWM was erased in the process).

So guys...How can I install this kernel w/o the CWM?..or better than this, how can I install CWM on my nvflashed P990?.

Thanks a lot!
[LG Optimus 2x] demoniac51:
you can take full advantage of your device's GPU, because the tweak Disable CPU Rendering .

Normally :

- performance boost

- speed boost

- increased responsiveness

- better audio quality

- apps such as Facebook that would become slow and unresponsive are suddenly blazing fast.

Good night, i go sleep, i am french 03:32 for me ^^.
[LG Optimus 2x] stonebear:
Wouldn't just ticking "force GPU rendering" be enough?

Your'e an hour ahead of me in England, we should be asleep, yes. :)

---------- Post added at 02:44 AM ---------- Previous post was at 02:42 AM ----------

You installed this ROM? Then CWM was installed when you Nvflashed, forget what ROM manager is telling you, it is there! :)

Just nvflash this Homero ROM buddy and then you have root and CWM for gb

Then nvflash this ROM, then flash the sp2, that's it buddy

Hope it helps

Flashed the ROM and everything looks to be ok. Just got some issues about the time and other things already mentioned. Right now, testing to flash leaked 28G baseband on phone and see if that addresses the time issue. As for OC, 1.3GHz does work once the SP is installed.

[LG Optimus 2x] ToesNZ:
go to wifi settings, use the menu button to get to the advanced menu & change wifi on during sleep to never. This fixed the wifi drain i experienced.

[LG Optimus 2x] stonebear:
Thanks, I will try screen off and lock.

On the other issue, I have found wifi drain still bad even when I select "never" to the option wifi during sleep. It could just be the way battery use is reported, maybe GB and ICS report differently. My battery drain overall is not bad with this ROM especially now I have under-volted a lot.

earlier i had unknown baseband and battery was draining badly because of that.....so now i flashed 1035.21_20121110

still same error..RIL apps not recognising phone
[LG Optimus 2x] Topogigi:
Those apps are for GB and they need to be updated to use the new ril naming convention. A simple and dirty workaround would be renaming the ril library into build.prop but it breaks rom integrity and I don't want to do it.

Hi, Topo

I will try with https://play.google.com/store/apps/...1bGwsMSwyLDEsImNvbS5za3ZhbGV4LmFsc2FtaXhlciJd

BR.
[LG Optimus 2x] ThunderRoad:

Although, tried Volume+ and had changed all the volumes except Radio FM app....

i try it.

but, for me, not solve the problem. max value to enter is 63 and the volume still rest low.
[LG Optimus 2x] aigaming:
I remember back in the days that i had that low sound fm on gb also;)

I also remember that Stefans kernel with voodoosound implemented boosted fmradio sound volume so i was sattisfied;)
[LG Optimus 2x] yukkio:
Yes, It doesn't work for me too. CM7 enables bluetooth when you use the radio fm so if we increase bluetooth volume may be will fix it.

Yea, battery is not good for me either, wifi in particular. I am using V28G BB too. I just accept it as it is very early days in ICS for us O2X guys. :)

edit

I should add that the battery is not actually bad either, especially as I am undervolted by -75mV at all frequencies up to 1Ghz and -100Mv at the 1.2 max OC that I use. Battery is like a "normal" phone which compared to Django Manouche with an SS kernel seems "bad".
[LG Optimus 2x] demoniac51:
@stone : check option forcing GPU is not optimal because libGLES_android.so is priority on libEGL_tegra.so. Egl.cfg give the priority with the first line. At final libGLES_android.so crush sometimes libEGL_tegra.so.

Best explication on google and on the best kernel for other telephone (GS2, GS3, HTC...).

If you cannot go to the thread linked in the OP and read the instructions, then you have no business flashing roms to your phone in the first place.

The script basically holds your hand and guides you through the process anyway, so try taking the time to read what is said on screen and choose the options that you think are best for your phone. You can always change them afterwards if you don't like the result anyway ;)

[LG Optimus 2x] Topogigi:
Checking it it simple with quadrant benchmark (it does sense 2d gpu acceleration as it does not enable it by default). Try enabling the parameter, run the benchmark and then do the same after disabling the parameter. You will see what I mean (check 2d score before and after). Your hack is not useful anymore since we have an option that forces 2d GPU acceleration directly from a menu. That's all.
[LG Optimus 2x] louiscypherbr:
Simple solution: change nvflash properties to make it executable before starting the process. Try this:

chmod +x nvflash

Than start the flashing script as you did before.

[LG Optimus 2x] Topogigi:
A quick update on what's going on under the hood for the upcoming SP3 kernel:

1) I'm testing a patch to solve excessive wifi drain and it looks very promising judging from the first tests

2) Ram OC to 333mhz (Hynix ram chip on our device is certified to run @400 mhz but it actually runs @300 mhz...)

3) It seems clear to my eyes that 3D is capped @60 fps, so overclocking the avp is unuseful

4) memcpy patch to achieve higher rate in memory copy operations

5) zsmalloc memory allocator in place of regular xvmalloc: that should give better performances for zram avoiding or diminishing memory fragmentation

Stay tuned as usual: release date is scheduled for the first days of next week when testing phase will be over.

Performance increase in benchmarks is marginal, but snappyness during device use is greatly increased with these patches.

Obviously all the commits will be on my github for other developers benefit
[LG Optimus 2x] demoniac51:
Good, impatient of test on benchmark. Possible OC at 1.6Ghz ?

I did not mean your patch. I meant "the patch you are talking about". So it is clearer, is it? For the rest, placebo effect is powerful in you! 3D is not influenced by any of the files you are talking about, and without gpu acceleration, 3D would be so slow you could not bear it and the most part of games and 3D apps would simply not run. So, we are only talking about 2D gpu acceleration. The paramter in dev menu forces it active just like the patch you are talking about. Stop and peace: if you want to apply the patch against every evidence, it's your choice: as I said before it's a free world....
