[Nexus 7 (2013) General] bcvictory:
After doing this guide for the OG Nexus 7, I picked up a 2013 version. I'm loving it but my battery life has been a bit all over the place.

I decided to look into kernels and I have come up with the same guide/tests/results that I did on the OG Nexus 7

I was intrigued and decided to work this out for myself and share it with the rest of the community.

This is not meant to hurt the makers of these kernels.

But FIRST, it is not a fact that there is a 'best' kernel. 'Best' is an opinion and everyone has a different opinion.

I personally believe there is no 'bad' kernel and none of these kernels I have tested perform badly or lag heaps.

People still like to push their N7's as hard as they can though.

Please take my results with a grain of salt. This is hardly scientific and results will vary heavily. This is just my results.

The Main 2 Features people look for in a kernel are:

Performance

&

Battery Life

Some people prefer performance over Battery, or vice versa, or an all-round kernel.

My Setup:
