Improved battery life with TLP daemon

[Surehand53]

In one of the recent Manjaro system updates TLP was mentioned as an option to power-profiles-daemon to manage battery life for the Pinebook Pro.

On the Pinebook Pro the TLP power management gives subjectively better battery performance over power-profiles-daemon. Especially sleep lasts over night without problems. 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.

If you are interested:

## Install TLP

Code:

$ 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)

Code:

$ 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

You can check the config with:

Code:

tlp-stat --config
tlp-stat -p
tlp-stat -p -v

If you want you can set `CPU_ENERGY_PERF_POLICY_ON_BAT` to `performance` as well.

# power-profiles-daemon
To switch back to the **power-profiles-daemon**:

Code:

$ sudo pacman -S power-profiles-daemon
$ sudo systemctl enable power-profiles-daemon
