Pit Stop: Please Refuel and new Bumpers - Part II

Just in time for the new year, the revived Apple Macbook Pro with Debian from the first part is back on my desk. It served well in December.

Linux Smartphone Project - Part III

Today I will report a brief description of the battery and power management of Mobian on a Pinephone. Reading the battery parameters from the console was already quite special. The usual way with upower was not successful and provided only zero values. Without ACPI the readout only worked with: # cat /sys/class/power_supply/axp20x-battery/uevent My first measurements: At idle with active mobile network, BT and WLAN and 50% display brightness the power consumption is about 2.
