In one of the recent Manjaro system updates TLP was mentioned as an option to power-profiles-daemon for the Pinebook Pro (PBP).
On the Pinebook Pro the TLP power management gives subjectively better battery performance over the . Especially sleep lasts over night. My PBP is one of the earliest (second batch, I believe) and yet with TLP the battery performance is great.
The downside is that the PBP user interface feels slightly more sluggish in KDE Plasma. Everything seems to be a bit slower than it used to be. This might be different in a simpler (tiling) window manager. The TLP documentation mentions that their power management suits light users best (writing, etc).
However, the battery performance feels much improved.
It is now a matter for the user to choose if they prefer performance over battery power. Current version is 1.7
Install TLP
$ sudo pacman -S tlp
You will be asked to uninstall power-profiles-daemon, say yes.
There is an additional package tlp-rdw, check in the docu if you want that.
To enable the service use (and reboot)
$ sudo systemctl enable tlp.service
Config
I have used this config change to improve performance when power is plugged in:
Edit /etc/tlp.conf and un-comment and update:
CPU_ENERGY_PERF_POLICY_ON_AC=performance
If you want you can set CPU_ENERGY_PERF_POLICY_ON_BAT to performance as well.
You can check the config with:
tlp-stat --config
tlp-stat -p
tlp-stat -p -v
Here is a link to the TLP documentation.
power-profiles-daemon
To switch back to the power-profiles-daemon:
install
sudo pacman -S power-profiles-daemon
To activate the service (and reboot:
sudo systemctl enable power-profiles-daemon
