Disable some cores for reducing heat/battery drain? - LG G Flex 2

Hi, I have just rooted my H959 on android 5.1.1.
Even playing games without stunning graphic like "Puzzle and Dragons",
my phone's temperature is still high and it drains a lot during that.
I am thinking about disabling some CPU cores for reducing heat/battery drain?
Is it a good idea to disable let say 2 cores to make it perform like S808 (with better GPU tho) ?
Anyone tried this before and how was the result?

Just use Kernel adiutor. I haven't noticed a major difference from switching to 2(4 little + 2 big), but I've been using 2 for a week or so. I played NFS and The Room 2 with no issues.

Done the same with excellent results.

Hi guys
Hoping you Kernel Adiutor veterans will be able to assist. When I go to the CPU page to disable some cores, the refresh icon in the top right just spins for ages and ages (sitting at 10 mins so far) and I get no options. Other parts of the app are fine.
Any ideas?
I tried the play store app as well as the f-droid apk.

I have only seen this when the phone was hot from games or benchmarks. Whenever the big cluster is disabled due to heat kernel adi will not behave properly. However, you might need to install busybox from the play store in case you haven't done so.

Ok...it seems it does this when it overheats. When it's cool it works fine. I do now have another issue though. When i try and disable bigcores 2 and 3, they come back on after one or two reboots.

Because when I do that it leaves them off even after a reboot or shutting down the phone. I noticed if you disable every big core sometimes big(1) will turn itself on. This might have something to do with the controller that maintains the CPU cliatwrs.

Thanks for the explanation. Out of curiosity, are you using the stock kernel?

[Q] help with my battery performance?

Can anyone look at these screenshots and advise me on how I can get better performance from my battery? I just flashed SkyICS (latest version) hoping to get better performance from my battery, but it doesn't seem to help. This is with what I would consider medium to heavy usage. I used my phone most of the day to browse the web and check facebook.
Any ideas?

Looks like the screen has been on for at least 4 hours. All you can really do is underclock it and freeze all the stuff you don't use.
Guess I will research how to underclock.... any good starting points?

I prefer no frills cpu. It will report the wrong settings when the toast pops up, but if you check cpu spy you will see it's working
Here's a couple basic and obvious tips and you might already know this, but no one has mentioned it yet in this thread so...
Turn wifi off when there are no wifi networks to join, but I've heard not to let it sleep when you are wifi connected.
Leave bluetooth and gps off when not using it. I don't let allow any of google's location services to run in the background myself. Not sure how well that helps the battery though.
Some people say leaving off autobrightness turned off will help battery life and some say leaving it turned on is better for battery performance. I'm not sure who is right but you might try it both ways and see if one is better for you.
I've tried most of those things and they don't seem to help.
I'm in an area with lte but coverage is spotty at work. Could that be what is mainly killing the battery?

Phone extreme overheating& battery drainage

So since yesterday every time I use my phone or even charge it my phone gets extremely hot! The screen especially and the back where the camera lies. I charged my phone for 6 hours there with no use and it has only went up a 4-5%. Ive not installed or downloaded anything recently that could cause this issue. I was wondering if anyone could help or have had such a problem and know what there is to do? I'm running the latest viper with elemental X 8.1 stock elemental settings been on both for at least a month or 2.

Try changing kernel, letting phone sit off for some time, or if all else fails do a clean install. Something i do when any of my phones overheat but wouldnt recommend for everyone, is i zip it up in a zip-lock bag and put it in the frig for about 2-5 minutes. But like i said works just fine for me everytime but dont recommend it
I don't recommend putting hot electronics in the fridge or freezer due to condensation.

Actually Venom Tweaks includes an option for status bar or notification drawer that displays current CPU usage. Theoretically you could run some apps, pull down status bar and check if both cores are in use. Having one core activated running full throttle would easily turn your phone into a hand warmer

I knew that but when you provide someone with information that you do not recommend a user doing, you should explain why so they understand the risk associated. Especially in a case where their phone could be damaged beyond any chance of repair. Don't you agree?

Correct. But putting the phone under some form of stress such as running games or watching YouTube videos ramps up CPU frequencies as well as initiating the additional core.
According to comments in development thread, OP has solved over heating issue with an RUU.

Good to know the issue is solved
cause even i had some issues with heating.. even for a small games my cpu tem is 50-60 and battery around 40!
It isn't unusual for this device to reach those temperatures during battery/CPU intensive apps or games. I've had it happen many times, games like Scramble With Friends (and other With Friends games) do it quite badly, as well as Maps, YouTube, and several others.

Nexus 5 lagging

Going through some threads it seems most dont experience any lag so im wondering what the problem could be in my case i sometimes notice slight lags when opening/closing app drawer, switching to quick settings, opening/closing apps (turned off animations so not really a problem now) and a few other instances is this normal? it got quite bad so i unrooted it and locked bootloader then unlocked and re-rooted and at the moment i am on stock rom, stock launcher and faux123 stable mainline 11 kernel

Doubt it's your kernel. I'm running stock and suffering as well :/ It could also be a defect, some run fine others don't. Same with the same speaker issue, some newer owners especially the red ones claim it sounds better as the old ones.

Try switching to ART runtime, it seems to be much smoother. Im using Franco's kernel with a lot of downgrading in setup and yet I don't experience lags.
I did think about switching to ART but to be honest i dont want to lose anything in terms of stability but hopefully soon it will become part of an update so if lag is normal on dalvik now i dont mind waiting i just wanted to see if its normal or im doing something wrong

I'm sure that the problem could be around some settings with faux kernel. I use it too but recommended settings foe nexus 5 seem to cause some lag for everyone as it's more for saving battery life...

Installing updates from Play doesn`t make the phone laggy unless there is a problem with an app or some apps. Rebooting after installing updates clears most problems most of the time.

[Q] Why does my Nexus 5 lag?

Hi guys, so I recently bought a nexus 5 I just got it like 5 days ago. My problem is that I have some lag problems. My phone lags when I play games like Dead trigger 2. I also have this game called Kritika, I don't know if you've heard of it, it's from Gamevil, and it lags pretty bad. So why is this? It's a Nexus 5, I shouldn't have problems with the Snapdragon 800 processor. I also seem to have a little stutter in fruit ninja. Is it just me or do I have a defective device. Or is there nothing wrong with it? Can someone please tell me whether I should send it back or not? Thank you.
Is it on stock? If no reflash stock then factory reset the device. Then load nothing else but the game. If it lags it hardware.

I would bet on thermal throttling like everyone else is saying. I noticed that although my Nexus 4 got absurdly hot with a raised thermal throttle, games ran better. That phone was a launch device and is used by my dad every day now without any lasting effects. I've done the same with my Nexus 5 with similar effect, although it doesn't seem to get as hot as my old phone. I would say that it's safe to do, and should get rid of the lag

Does your phone heat up while its lagging? If so, it would be because of thermal throttling like the other have mentioned (reducing CPU frequency so the phone can cool down)
You can flash a custom kernel and either remove thermal throttling or increase the amount of temperature of thermal throttling (so it will reduce CPU only at higher temperatures).

Yeah it does heat up while it's lagging, but the problem is that it doesn't take time to lag, it just starts lagging when I start the game up, not over time, so I was wondering if it was a hardware problem.

You know what guys I suspect it's just those two apps that lag, cuz other games run just fine
