How can i reduce my power consumption? What else should I do?
I installed an configured TLP and powertop, configured tlp and run auto tune and configure on powertop.
If i adjust the brightnes powertop says nothing about it, almost the same usage.
And sometimes “USB DEVICE: USB 3.0 …” uses 1-1,5w.
I have 2x24wh batteryes.
You shouldn’t run both, though.
Powertop can, as far as I know, adjust some things - and make them permanent
via changes to config files.
Then comes the tlp service, if you have it active … and applies it’s configuration, overriding/changing the configured values.
You can use powertop to identify the points of interest and then configure tlp using that information.
That might be a flawed reading/report.
Or it may actually be true - depending on how the changing of the display brightness is implemented in the hardware.
(it may dim your display by wasting part of the energy through a resistor
the display brightness might change - but the consumed energy might not
… this is probably not the case - but possible )
similar re the USB device readings
I mean i use powertop to track what eats my battery, nothing else.
i don’t really understand the second part of your answer, sorry.
It was a mix of a failed joke and wildly inaccurate speculation anyway.
To write it felt like a good idea at the time …
Everywhere i saw everyone is using TLP and POWERTOP at the same time.
Sorry for not understanding it :c
… your experience, not my experience though …
I’m (still) using TLP
It was introduced and used by default in every new installation of Manjaro
Some now may not have that active anymore.
But it was the default.
works just fine, too
Having two independent solutions
tlp and powertop
“messing” with power related configurations
at the same time
does not seem like a very bright idea to me
… as the two can evidently come to different “solutions”
kind of fighting with each other
making the result unpredictable
I have a thinkpad X1C6 wich has pretty similar hardware. At the time now I run only
auto-cpufreq as a test and it’s working fine so far.
For power saving route with
tlp installed, I would suggest this tutorial here in the forum.

fwupd - ArchWiki (is in the manjaro repos and i highly recommend it)
