Description Henning 2023-03-12 20:47:48 UTC

SUMMARY

This could be a really useful feature. I would imagine the energy saving like:

- disable all animations (set the speed to max does that right?
- disable all kwin effects that use shaders, transparency or animations
- set screen turn off to 1min on battery
- reduce number of background apps
- dont check for updates or appy updates

Things users could enable/disable
- change power_profiles_daemon to use energy saving mode
- set OLED black theme (for some devices, plasma mobile etc. future stuff)

If possible a TLP integration would be great too. Even if it was just adding "tlp start" to the executed scripts on battery mode

Seems like it could be a sensible idea in general. We'd want to make sure that the things it does *actually* save energy, though.

Comment 3 Henning 2023-03-14 11:28:11 UTC

what other ideas would you have for energy saving? These are all things KDE can do currently afaik I could think of.

Things like reducing the CPU cores to a total of 4 (less may be worse), limiting Frequency e.g. would be great too, but are pretty hardware-specific. There are general tools for AMD for example, this could maybe work.

But for me just display timeout does a lot.
