Battery 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 2.5 to 3W. At 100% display brightness it jumps up to 3.5 to 4W each time without any apps in the background. From the desktop perspective this may not sound bad, but in fact it is. Read more

A hotkey like in iOS (home + on/off switch) is unknown to me on the Pinephone. The classic desktop Linux tools like Gnome Screenshots or Peek are installable but do not work properly. It’s quite banal, they fail due to the fact that I cannot trigger any hotkey on a touch display UI. As a solution I have chosen the workaround via SSH and grim taking screenshots remotely in the background while in the app in the foreground, Waylands makes it possible. Read more

I finally think it’s time to move on and start a new journey. Away from proprietary, closed systems with their wiretapping assistants1, the uncontrolled extraction of behavioral data, the constant intrusion of a more less subtle nudgeing2 and the latent threat of simply being bricked3.
