[SOLVED] - [Q] CM 10.1 RC1 - disable cpu cores ?

is it possible that i enable only one core and disable all other cores of my cpu ? How???
I'm on CM 10.1 RC1 On v20a official - rooted - unlocked - with CWM recovery

You can do that by using an app called Tegra Overclock for example.

it doesn't have optimus 4x in the supported list

Our phone is supported, don't worry. We got Tegra 3 processor. I am using it daily to improve performance (mainly in games to overclock GPU and to REALLY force all 4 cores to work).
Here's a couple of screenshots that I just made to show you.

[Q] Battery-friendly ROM

Hi guys, maybe you read this question a lot of times...
In your opinion which is the best battery friendly ROM for our device atm? I don't really care about performance aspects because I'm not a gamer

I get +/- 1 day on stock JB (GPS always ON, data always On). Last time i tried CM (RC2) i didn't get 6h...

I'm currently getting a decent ammount of battery life with CM Nightly 20130613 + Idoak v6 kernel.
Also Stock ROM with Idoak kernel is good aswell. Just have my Governor set to Interactive and seems to do a pretty well job.

From what I've read/heard around. The CM RC version are alot more buggy and problematic than the Nightlies. I haven't tried the RCs myself tho the Nightly does feel pretty smooth and stable.

Which firmware?
Sent from my LG-P880 using xda premium

ROM has little to nothing to do with battery life, aside from the obvious settings you can select to turn opn or off features. what does influence battery life is how you use the phone and in particular 3 key elements
1) Kernel - Stock kernel is pretty limited, using alternative kernels will allow different governor and scheduler options along with frequency and voltage control
2) Tweaks - many unsuspectable little things can change the way your phone drains, probably the best way to start is getting pimp my rom from the plauy store
3) Apps - You will need apps to help managing and scheduling when and how the phone drains. LBE security master or any other task manager will prevent unwanted app startings and others like juice defender or other battery saving programs help with which interfaces are on and when.
Also keep in mind that if your phone is new the battery in the first 3-4 days need to settle and will change drastically behaviour.
Hope this helps
In any case a catania sto telefono te lo fanno prima della terza ricarica quindi non mi starei a preoccupar troppo

Grazie XD
In this case which kernel and governor do you suggest me?
Sent from my LG-P880 using xda premium

Stock rom, remove LG MLT and Google Backup Service and you should be good.
I can leave my phone for 2 days without worrying about charging it. However, with screen set to 50 or 100% brightness, the battery drains very fast.
Otherwise, keep your screen brigthness low and get a governor that lets you throttle the CPU. At 800 MHz,you should be fine. Also, dont use auto brightness, it will not help.

Thank you which firmware?

EuroOpen V20A if stock or CM, some nightly between RC2 and RC 3(Thats the last ones I tested that used to be good)

Could someone help on what r the steps for install custom ROMS and Wich one is the best for battery life I'm having very very huge battery problem. The battery it's long for about 3 hours tops and I need to keep charging always and also the overheat is extremely. I will appreciate ur help

Sorry but you should write a new topic for this problem... Anyway there are several guides in this section that revolve about how to install custom roms. Try looking there... However generally after installed a recovery you should do a full wipe (data/cache/dalvik) -> install zip from sd card -> choose zip from internal/external sd card -> [file directory] -> choose file -> yes

Im using iodak 6.0 and latest CM nightly builds. Battery is much better then on stock ROM and kernel.

I dont know if iodak improves battery life, but I do not think that battery improved with CM. It actually got worse for me,

XenonHD + iodak v06 has been very smooth and battery friendly. A day and a half of moderate use and I'm sitting at 18%

No replys?...

Cm (02/07) + Optimus Prime V1.9. I use cm because it's (IMO) the best way to enjoy the android experience. Also because all the mods are compatible with cm.
The reason i use this kernel is because of the performance/battery life.
Cheers

Stock v20a Euro with stock kernel I deleted some applications that come preinstaled and now everything is fine.Using stock because i like LG UI 3 and because i didnt yet installed CWM If anuyone can recomend guild how to instal CWM (best version for our phone) please do so
P.S. mine 20a Euro is unlocked and rooted.

Zaiben ROM and eternity project kernel, best performance and battery life, first time that I don't need to lower the graphics of real racing 3 to ir run lag free, also first time that I run butterly smooth mc4 and 10 hours sleeping with only 8% drop

Cyanogenmod 10.1 stable with optimus prime 1.8
Best batterylife/performance, and also... 3g isnt bugged
I just can't use optimus prime 1.9 or 1.91 cause my cel takes like 3 seconds to turn the screen on

@Jonte Thank you for quick explanation I already did unlock bootloader on my lg so now just CWM to go

The Last zaiben with stock jb kernel. With cyanogen and/or other kernel my phone gets so hot . Also i get a good deep sleep with this combo.

Great thread. I was wondering if all of you can provide screenshots of your battery life? Im still on stock JB and kernel, but rooted, with few apps frozen, but my battery life is still rather short.

well, I used to enjoy playing some Tegra games on it, but I just hope there's something to smoothen the performance and enhance the battery life as it is now still very disappointing.
I'm currently running V20A rooted still with locked bootloader ( I believe ). I have frozen several LG apps (if not all), and the battery life is still disappointing.

IceColdLG-P880_IceColdJelly_3.6_Final_HOX[PORT]by_SnXo. Very fast,stable,long batery life.I thing is the best rom so far.

Umm? So you play 38 hours with screen off? Including 30 hours without battery? Wow -- would you mind sharing that trick?
This is a really useful thread indeed, as one can not only learn which ROMs are available but also how stable/battery-saving etc. they are. What I'm still missing are the links to the ROMs sources. Would be great if you could include them! Thanks

I connected a mini starks reactor to my cellphone, also I play audio only experimental games hahahhaah
Sorry for the typo, I don't really remember what I was trying to say, maybe 40 mins of gaming because normally I play real racing 3, modern combat 4, for a 5 minutes periods of time... various times a day...

Yepp, that sounds more like it, and fully logical. Should have thought myself that there are some external chargers available also in the atomics sector; leaks are that common nowadays #D
Honestly: Yeah, I already thought you meant "10 min", but I couldn't resist the joke

Benefit of disabling CPU cores?

Is there a way to limit the amount of cores that can be active on a custom kernel? I am using eprj kernel and am able to disable 2 cores using trickster mod but I really want to try optimus kernel but I can't find out how to disable the cores
Also is there a significant battery improvement if you disable 2 cores and run at 1ghz or is it better to enable all cores and run at 716 mhz?
Sent from my Optimusx4 using xda app-developers app

I'm trying two cores in iodak at 1400 is really smooth but I can't tell anything about battery because I'm starting to try now, only thing I can tell you is that dual core at 1 is better than four cores at 716, why? Some apps runs great at 1 GHz and only use one core, so that app at 716 will work slow and laggy, there is not so much apps that works with all four cores enabled and that apps will work well in two cores enviroments

Thanks I can take a little bit of lag because I really want better battery life and am trying both 2 cores at 1ghz

If the phone is hot when charging then you will get the slow charge. You can overcome this by going into the hidden settings and enabling the unlimited temp charging under charge test. Bu you will have to do it each boot within hidden menu. or you could install Iodak kernel and enable the fast charge. Set max 1200 min 102 cpu in trickster mod and remove tegra overclock because that seems to cause fast batt drain and overheating. (don' ask my why but many people have reported tegra overclock causing this)

Hey thx for the quick answer I did remove the tegra overclock I do the hide menu thing about module test charging unlimited but the problem persist always I never tried with customs kernels and idk how to do it in any case I really need a help on this

If you have Clockwork mod installed and a unlocked boot loader its just a case of installing the Iodak kernel. pretty easy just look through the general section on how to do it.

Also if you tried the hidden menu unlimited temp charge make sure you have your usb cable unplugged or it will not work. Plug it in after you select the setting. But remember it does not stick so you need to do it each fresh bootup.

Well I did the trickster mod of the min and max but I really need to get done with this problem and I don't really know what to do

Iodak kernael is the best for your problem, Just try reading the forum under original android development for 4x iodak kernel. It tells you how to install and its not that hard.
