You can see, that the power draw goes down as the kernel version rises. From version 5.1 to 5.12, we see about a 10% improvement in heat, 30% in battery draw, and a 90% in load average.
The above sounds as if Linux kernel versions up to 5.12 were tested. But that can’t be right since the Linux kernel versions so far only go to 5.6 (https://www.kernel.org/).
What’s going on? Perhaps what is meant is not “kernel version” but some other kind of version number going from 1 to 12? And the 5 is just 5 as in Librem5, not “version 5.1 to 5.12” but rather “Librem 5, software-version 1” to Librem 5, software-version 12"?
