Quad core

[pool_shark]

I was curious to know if all 4 cores were in use.
They are.

Of course they are. Why wouldn't they all be used? Any good operating system (like most all in this day and age) will utilize all available cores.

Not necessarily. When you turn on Power Saving the phone shuts down 2 cores when not needed. Back on when needed. Do you really think you need 4 cores to text or even to play angry birds? Its a lot more efficient this way and doesnt waste your battery. If 4 cores were constantly on, your phone would he warm to the touch at all times.

I'm a power user so yes I use all cores almost all of the time because im always multitasking and heavy on video and high demand apps. My phone is always hot.

I just wanted to see it.
I used the command on other phones which were rooted to see which governors disabled processors.

How hot does your Note II get?

I am a heavy user but my Note II runs at only around 70 degrees F. All 4 cores run continuously even at near zero usage. I haven't yet had time to check the governor settings on my brand new Note II.

My RAZR MAXX used in the same heavy way with all the same apps on it consistently runs at over 100 degrees. On Gingerbread the second CPU was constantly starting and stopping. On ICS
both cores *always* run.


My Rezound ran at over 110 degrees.

My 3 LG Spectrums all ran at around 103 degrees (the first Hotplug governor throttleback setting).


The Task Manager in the System Tuner app is an easy way to observe the operation of the quad cores on the Note II.

If you are not rooted you can find your governor settings by doing a Logcat immediately after starting up the phone.

What command did you run? Some form of mpstat? I haven't had time to install Busybox on my Note II yet.

I'm not rooted yet, but I have better terminal emulator pro. It comes with it's own version of busybox.
I created a sar script that calls top with the c flag.

How do I root a lg marquite

Why are you asking that in a Samsung Note II forum?
