[Galaxy Note 4 General] bala_gamer:
The quality of the cpu used in the devices is identified by cpu binning. The better the quality the lesser the voltage it needs to run for the defined set of frequencies.

* CPU binning for sd805 running at 2.7 ghz has 2 versions RC0 and RC1.

* Looking at the voltage table RC1 uses much less voltage for lower frequencies compared to RC0

* The value scales from pvs0 (being the worst) to pvs 15(being the best).

The voltage tables for RC1 and RC0 is given below for reference (thanks to [MENTION=593514]twistedumbrella[/MENTION] for his github)

RC1

/* 2.7GHz RC1 */

If you compare the various binning values mentioned above

RC1 pvs15-bin requires 1000mv to run @ 2.65 ghz whereas RC1pvs0-bin requires 1150MV to run @2.65ghz

Devices with higher binning runs with less mv and thus gives better efficiency . In future it may also give you more head room for overclocking/undervolting

So what now ?

Lets check what binning values we have here on note 4.

* Use any root explorer

* Navigate to the below location

sys/module/clock_krait_8974/table_name

Example output :

qcom,speed2-pvs11-bin-v1

Do share your binning values here :)

Edit : Non rooted users please do post whether the above method is working or not
