[Galaxy Note GT-N7000 General] loryb84:
Hi, I did some tests to compare custom kernels battery usage and performance.

To evaluate the performance I used antutu benchmark(best of 4 runs),realPi (best result of 5 runs) and CF bench (best result of 3 runs)

I'm running Checkrom v5.

I used the latest version of the kernel:

abyssnote: 3.5c

Speedmod: k1-3

cfroot: 5.0

Fm: v 2.0

Franco Kernel

I used the kernels as they are downloaded and installed..without overclocking,or anything else,unchanged governor.

To evaluate battery life I did a test by my own: running stability test v2.0 for 20 minutes and look at battery %.

Then I also did real life tests.

Here's the results

------------------------------------

BATTERY TEST:

stability test (20 minutes)

-Speed kernel used 12% of battery

-CFroot kernel used 12% of battery

-Abyss kernel used 18% of battery

-Fm kernel used 20% of battery

-Franco kernel used 10% of battery

gps tracking usage

Using oruxmaps,screen always on at min. brightness,gps recording every second,phone on the desk.

I compared cf root kernel,speed kernel and AbyssKernel

Results:

SpeedKernel ---> 6% battery drain in 45 minutes of recording (at 30 minutes 4%)

CFroot ---> 6% battery drain in 30 minutes of recording

AbyssKernel ---> 5% battery drain in 30 minutes

FmKernel ---> 5% battery drain in 30 minutes

franco kernel ---> 5% battery drain in 30 minutes (8% at 45 minutes)

web browsing

test done using stock browser,wifi,minimum brightness and visited the same sites(various contents:flash,java,static pages)

Speedkernel ---> 8% battery drain in 30 minutes of browsing (1 hour--->16%)

CFroot ---> 10% battery drain in 30 minutes of browsing (1 hour --> 21%)

AbyssKernel ----> 10% battery drain in 33 minutes of browsing( 1 hour---->19%)

FmKernel ----> 10% battery drain in 31 minutes of browsing( 1 hour---->20%)

Franco Kernel ----> 10% battery drain in 30 minutes of browsing( 1 hour---->20%)

-----------------------------------------------------------

BROWSER COMPARISON

I was trying Opera browser..and I compared it with stock browser about battery life and using FM kernel.

Stock browser---> 10 % of battery in 31 minutes of browsing

Opera browser----> 7 % of battery in 30 minutes

BENCHMARK TEST

Speed Kernel:||Antutu: 5028 || Quadrant(after 3 runs): 4458 || RealPi(100000 digits):20.94 s || CF bench: 7342

CF Kernel ||Antutu: 6771 || Quadrant(after 3 runs): 4920 || RealPi(100000 digits):20.46 s || CF bench: 7147

Abyss Kernel:||Antutu: 6902 || Quadrant(after 3 runs): 5000 || RealPi(100000 digits):20.42 s || CF bench: 7360

Fm Kernel:||Antutu: 6847 || Quadrant(after 3 runs): 4906 || RealPi(100000 digits):20.60 s || CF bench: 7131

Franco Kernel:||Antutu: 6866 || Quadrant(after 3 runs): 6041 || RealPi(100000 digits):20.59 s || CF bench: 7049

BOOT TIME

Tested several reboots with each kernel.. and measured with a stopwatch the thimes between:

A - From Samsung boot logo ----> to little vibration

B - From Samsung boot logo----> to lock screen

Results

SpeedKernel ---> A: 19 seconds -- B: 26 seconds

CFroot ---> A: 22 seconds -- B: 29 seconds

AbyssKernel ---> A: 22 seconds -- B: 26 seconds

FmKernel ---> A: 28 seconds -- B: 39 seconds

Franco Kernel ---> A: 18 seconds -- B: 25 seconds
