Hey everyone, i Was wondering if it is possible to disable the 2nd core so it will run single core?
When checking System tuner, I see the second core jumps to 1.9 ghz some times, when using XSX kernel.

I'm on stock kernel that come with .50. CPU1 is offline most of time! And it's still perform very well!
Don't forget to hit thank, if i deserve it!

what's the main reason you want this?
The benefit of having 2 cores is that you can better multitask. If you want to save battery you could also try underclocking your cpu.
You would still have the benefit of multitasking with 2 cores and saving battery. (of course your phone would be less powerful, but that also goes for putting 1 core down)
I see cpu1jumping to 1.9 ghz a lot I dunno if it's a bug or what but doing nothing and just idle with screen on it jumps up from offline to 1.9.
So I was just wondering if it's possible to turn it off completely or make it jump to a lower clock.
Battery is good if screen turned off, but screen on it consumes battery fast, and my clock is normally 1.5 ghz ondemand, and cfg

system tuner...
Yes sys tuner pro works pretty great. U can also set a different min/ max for each. That said if you are on the newer ota freeza has a kernal that keeps both cores active as well and then u can use system tuner to manage the min/max for both however it isn't overclockable.
I should mention that both cores actually get activated on demand by default and apps like Daemon Control, which is a nice front end for the overclocking daemon virtuous oc will actually overclock both cores as well, however CPU1 will only be active when needed. hope that makes sense.

Gpu overclocks itself on-demand, I didn't implement anything for user control, instead it is better to be this way

Be mindful of governor settings. Research your kernel before taking on OC mods.

I'm on Infection 2.9.1 and I also flashed the latest Hiro kernel. I downloaded Trickster MOD to change settings. I'm getting a lot of reboots but I'm also trying to save as much battery as possible. I have no idea what settings to mess with and what to change them too. My phone settings had a Performance settings where you can change CPU settings and I also have Trickster like I said, just don't know which to use. I think both are on which might be causing problems? I posted some screenshots, could some please help me get something going? - Thanks guys!

Oh, and "set on boot" means its turned on, correct?
If your using a kernel app like trickster mod than make sure everything that says set on boot under system\performance is unchecked

OK I got that part but what settings should I use? I'm not good with kernels and these apps, changing voltages, etc. My phone has been overheating and boot looping a lot. I also want to get best battery life possible. I just don't know what settings to use. Also if I'm using trickster to tweak my CPU shouldn't the performance in my phone settings be shut off? I'm open to using another tuner app.

Make the sleep frequency be 384 (whatever the 300 MHz is) been running that way since launch of 2.9.1, no issues, besides the native tether (only buggy issue I use) and whatever else others reported, I assume. Never used the features that this report so I don't know.

There is an option in kernel tuner for it. Some kernels do not support changing that setting though.
Now that he released it, this is what I used on infection the past week when 2.9.1 came out. It works amazingly. On install it gives you options for sleep 2 wake and screen off frequency (I set mine to on and 384 with no adverse issues)

No clue what your talking about? What does that jb port do? Also are you saying I need to get rid of trickster mod and DL kernel tuner?
Edit: I downloaded kernel tuner app just even more confusing now. It has cpu0 and cpu1 and about 100 other options.

So this kernel will replace Hiro which I'm using now?
And you keep saying to change sleep freq to 384? I'm guessing that will fix my wake issues. What about fixing my battery life and boot loops?
Sent from my Infected Rezound using Tapatalk 2
Can anyone else chime in? This is what I'm trying to accomplish.
1. Fix boot loops
2. Stop the over heating
3. Make battery last as long as possible
4. Fix the wake up issues. When I press power button to wake phone the capacitive buttons turn on but the screen doesn't.
These are the issues that I'm trying to fix. Like I said I'm currently on infection 2.9.1 using lastest hiro kernel. I need some helping finding the right kernel to use and what settings to use with kernel tuner or trickster mod app doesn't matter.

That kernel will replace hiro. You can set screen off freq upon flashing in recovery. The below pictures is my current settings for the past week and only had one freeze (it was testing something out for the kernel before released). In the picture, screen off and idle freq are disabled as you change settings when flashing the kernel. (During install, aroma will ask if you want to do default or custom install, custom for more options.) Pictures are in thumb format so less space is used in the forum.

OK thanks for the detailed instructions I'll try it and see if my phone improves.

You can change second core to something else. Lionheart is a performance based governor. I use it on second core with mpdecision having a longer wait to turn on core 1 for my personal optimal battery saving/performance. Core 0 is set for power save bias so only when I need speed, core 1 will kick on with some higher MHz while CPU 0 catches up a little later.
Battery savings isn't too great, but unless you are doing some CPU intensive stuff, it does pretty well on battery.
This is CPU times today... Mind you, I used my phone for a total of 4hrs from 530-1640. The reason it stayed at 192 a lot was because I just did texting, web browsing and some other low CPU intensive tasks so far today (about 20-30mins of awake time in 192 was screen off streaming a local radio station.) Ran buttery smooth though.

You most likely have a performance option that came with the Custom Rom or are running an app that has System App access , which will over ride a User App. Double check all apps and settings to see if you have any other programs that have system user rights to your CPU, that is most likely what is over taking your desired settings.

Thanks for the quick reply, I'm on the Android Revolution HD 8.0 ROM now, that is probably the reason for this. Can I do something with this?
Sent from my HTC One X+ using xda app-developers app
Open up the app your using to undervolt, these should be an option to restore default values. Once back on default go ahead and open the programs' App info and disable or freeze it. Reboot and run your CPU spy app and see what is taking charge of your voltage. Also possible your voltages are not sticking which has to do with the ROM. Id suggest running profiles for CPU rather then undervolt. I. E. 534 mhz - 1434 mhz when screen on, 348-1012 when screen off. SetCPU is what i use. You have less of a chance of frying the motherboard and doing irreversible damage to your phone internally

Undervolt has to do with lowering the power that goes to the battery. when desired mhz occurs, where as underclocking has to do with specifically CPU processors and with a specified setting (screen off, music app on) occurring. Just to clear up my previous post. Undervolting the battery use to do wonders on phones a few years back because of all around poor battery life on most devices. But nowadays it is pretty pointless.

I would like to know what your thoughts are on usage of these apps, do they work?
I have personally used,
Greenify
Es task manager
Du battery saver and there cleaner app
But I have read they use more ram then they free up etc..
Also xcore, and core2 management. (these shut down one core on dual core devices) Do these save battery or not? Surely since these phones are generally optimized for dual core processors, closing one causes the remaining core to work twice as hard and wont save any?
Are any if these applications worth having?

Since few weeks I'm using greenify, but can't see any difference.
However since the beginning of my android adventure I'm using advanced task killer, set it to aggressive mode. This does the job pretty good (specially the older versions).
I'll have to try those core disabling apps.

Ok strange, I thought it was because the s4 was quad core but just checked and the zoomis dual core.
How do you know it doesn't work? I checked via cpustats app (free in the app store) it shows when I use xcore or core2 manager that one of the cores are off line.
You could try xcore?

You can't use xenon as torch and I don't own this device anymore.

Du battery saver is useless app. Basically all these battery saving apps do things which you can do from Status Bar. (Like switch off Wi-Fi, Data, B/T etc).
Greenify is good app to freeze apps, but shows effect only if you freeze large number of apps.
But xcore, core2 and CPU Controlling apps are best. They give major battery boost.
I don't have dual core, but if I underclock my phone's CPU I get battery boost of 2-3 days.

See when I use xcore etc my phone slows but battery seems to drain just as quick. Then there are goveners and io schedulers, if I use interactivex does that only use one core until the second core is needed?

I don't know about interactivex. I own a single core phone.
But disabling 2nd core definately gives battery boost.
I have tested it on my Laptop. Disabling 2nd core gives lot of battery boost (and a bit of lag).
