Hi guys, I recently installed Linux mint on a spare laptop I had to check if I can daily drive this and since I run Syncthing Windows setup on this device before and I essentially want to replicate that setup here which means Syncthing starts up automatically on login but with the condition that the device should be connected to ac power and if it gets disconnected kill the process right away. I could easily have this in Windows setup and also in Syncthing-fork for Android with a simple toggle. How can I replicate this Linux mint as well?
If you use Docker/Podman to run Syncthing (a little tricky but possible) you can limit its CPU usage, which is usually the main source of power drain (besides GPU processes). If your usage is like mine Syncthing is idle 95% of the time and I wouldn't notice if that 5% took longer than usual to do its thing.
Will throttling the CPU use less energy? Phones often do the opposite, they race to idle
In theory, yes, but it wouldn't be as significant as stopping it entirely (or pausing it instead of a hard start-stop). I only mention CPU limits because it's extremely easy to implement.
