Optimizing Battery Management on Linux Phones: A Dive into PinePhone and Librem 5

You may be interested in controlling temperature and CPU/GPU frequencies:

It is possible to create/modify trips/triggers for CPU/GPU thermal throttling:

The CPU is set to start thermal throttling at 50°C - first by limiting the frequency to 1.0GHz, and then starting at 60°C by idle injection. Additionally, the GPU gets throttled at 65°C as well. The critical temperature at which the SoC is forcibly shut down is 90°C (I have hit that in the past on devkit and some early batches when compiling some big stuff, but so far never on Dogwood or Evergreen). These values are set in the device tree: arch/arm64/boot/dts/freescale/imx8mq.dtsi · pureos/byzantium · Librem5 / linux · GitLab
