Hey Ppl
I see there is an App to Sony smartphone, to disable one CPU core to improve the battery.

Is there anything similar App to Samsung devices lik S2?

You can change when the phone uses one core or two in the tweaks for Siyah and Dorimanx kernels but the one core would run for longer to process the same amount of work load so it would not save nearly as much as you would expect. The phone already puts one core off when it is not needed. That said I have not tried it so cant back it up with figures
In STweaks it is "MIN Frequency for 2 core"
CyanogenMod 11 M5 is great, no doubt about that, performance is better, it's way cleaner and streamlined, less bloated and the latter...
It's been a few days probably, almost a week since I've been using CM11, it's somewhat stable, but after digging across the new features and whatnot, I came across one small hiccup.
Screen recording is VERY LAGGY.
For a phone that sports the following specs:
1.4GHz Quad Core Exynos 4412 Processor
1GB RAM
Mali-400MP4 GPU
and the rest which I'm too lazy to type...
I find it difficult to believe that the phone would be so laggy, close to an unusable state in screen-recording mode, I've tried other apps like screencast (am I right?) and REC. (one of the most popular kitkat recording apps) but all seems to have the same very laggy results.
I've used the ADB method (which I believe is the one also used by REC.) in kitkat which is really laggy as well.
Tried workarounds:
- Rebooting
- Setting minimum clock to 1.4GHz
Video showing how laggy the device is in screen recording mode:
I also saw another guy using an S3, but a different version (SH-i747)
The only main difference between the int'l version and his version is that the SH-i747 has 2GB of RAM, a (lower) dual core processor, and (not sure if better or not) Adreno 225 GPU
I really really really hope you guys could help with this prob, I don't really see why screen recording is so slow with a phone at this arsenal. Please do help, much appreciated
Device Info:
Device: Galaxy S3 int'l [GT-i9300]
ROM: CM11 M5
Kernel: Stock CM
Android Version: Kitkat 4.4.2
Hey,
Have you found solution ?
I think its laggy because the Galaxy S3 doesn't have this feature enable by default. Plus we're talking about an experimental feature here. Hopefully this mod can be updated to perform better.
My main question is ,why the android devices are not being sold rooted already?
why are they unrooted?
will a rooted device with 4 or 6 cores,running a PERFORMANCE governor,run faster than a iphone's dualcore A7 or A8 ?

android phones and Iphones are not usually sold rooted or jailbroken, because you have full access to the system and can brick your phone in 2 seconds if you don't know what you are doing(this is 2/3 of consumers) I phones are junk IMHO bc they restrict what you can do. also, It is not solely the cores you have, it is also the frequency that they run at that determines how fast the cpu is.
Buy a Zopo, the last Models (KitKat) come with root.
The governor only "say" in witch way the CPUs will clock fast er and slower. The max Performance is given by kind oft CPU (Tegra, Snapdragon, MTK) and the frequency.
And don't forget that this bitten Apples send all processes in background when a finger is touching on the display and the UI will get all CPU.
yea.keep going...
just tell me ,why should i buy an android if i wanna just to make my work with my mobile?
i just want to make calls,use facebook,use viber (all together ) and not lagging'
if i make all cores work together at android,will i achive a better performance than iphones?
(i dont care how apples works.they are just fast)

Running all cores at full blast will kill your battery and cause overheating and shutdowns. With your Android, all cores do work together, when needed. And when not needed, some cores will be at idle and active cores won't be running at full speed.

my question is still the same.
if i enable ALL the cores running together,not necesserally at full speed,will i be faster than an iphone?
would you buy a car that has been modified by others? so as the phone

My answer is the same. DON'T DO THIS.
Because root is useful only for users who know how to do with it?
Hello everyone,
I'm looking for information. I have the current use case:
My smartphone is a Sharp Aquos Zeta SH-03G with lollipop 5.0.2 (I didn't get a choice on the device I could get )
By digging a bit in the system I found out that this smartphone is configured somehow to not use the full CPU capacity. It justs use 5 cores out of 8 of the snapdragon 810 whatever the activity on the phone.
However all the core are seen as possible to use by the kernel with correct frequencies.
Only the core up to 1.5Ghz are use normally. for the core up to 2Ghz, only one is used and not at the top frequency (max 1.4Ghz)
Which make this phone to act as a 5 core up to 1.5Ghz. I'm just curious to understand where I should look like to see where that configuration is done.
Is it in the custom kernel source code? Is it some arguments given at boot time? Is it in some configuration file somewhere on one of the booting partition?
They release the source code of the kernel so I just give at least a quick check in the processor core frequency definition for a snapdragon 810 and it was looking like all is defined approprietly to use all of them. Also the system report that it really see 8 cores and that 8 cores may be use if needed...
Any help appreciated, thanks!
HI All
thanks for taking the time to read this and helping me out and bare with me as I'm fairly new to posting on these forums
Ive got an IQI I3 smartwatch that I bought from china , IT tuns android 5.1 has 512mb of ram and uses the mtk 6580m quadcore processor
My issue is that the SOC runs all 4 cores at all times and this smartwatch has a small battery so it drains fast
ive rooted the watch using kingroot and installed several cpu control apps but when I disable the cores through those apps they just instantly get re-enabled , does anyone know why this is happening ? is this a kernel issue , can I modify the kernel to stop the cores getting re enabled ?
Thanks
