Battery life issues ( >3100 wakeups/second)

Hello there,

I am having a very bad battery life using garuda on my Thinkpad T14 (gen 1).
I am looking at the overview of powertop and I am having 3100 wakeups per second!! And a discharge reate of ~10 W.

I have tlp configured and everything should work fine without AC but I am getting a max of 3 hours usage with a 90% charge...

Is there a way to fix this ?

That battery should provide 5 hours battery life at 10W per hour.

What is causing wakeups?

What other processes are running?

Have you calibrated the battery recently? Some batteries will lose accuracy when not charged fully and therefore the capacity/charge level will seemingly randomly drop at some point during discharge.


Disable all performance enchancements from Garuda Assistant and enable all powersave optins.

Oh, also have a look at How to use AMD P-State in Linux 5.17 - Kernel & Hardware - EndeavourOS , this can help a lot with lowering the idle state frequency.

(I am dual booting) on windows I do get around >5 of battery time.

A lot of processes are running, google chrome has most of them

/opt/google/chrome/chrome --type=renderer --enable-crashpad --crashpad-



I have not calibrated the battery, will look into doing that

If you look at top or htop then you can see which ones are using CPU time.

Also don't forget to answer my other questions so we get a good picture of what your system is doing.

If you get 5 hours in Windows, then 10Wh discharge rate in Linux is about right - there's possibly not much more optimisation that can be done here. Browsing pages and watching videos in Chrome will take battery life.

I just did and I am still getting >3000 wakeups/second.

I do get

target not found: intel-undervolt

Should I download that and enable it ?

from htop I can see chrome as top cpu heavy, htop itself and xorg

since the time I posted this topic, the battery has dropped more than 63%

Was that a smooth reduction over time, or was there a sharp drop at some point?

If there was a sharp drop then the battery needs to be calibrated.

it was a smooth reduction over time

and what are you doing in Chrome?

Nothing too special. I have 10 tabs open. one of which web whatsapp and 2 youtube.

Right, which I pointed out before, watching videos on YouTube can take a significant amount of CPU time and therefore battery power.

This will also maintain a background connection for notifications, keeping your wifi connection alive and again using more power.

Try reducing your browser footprint and see how CPU and battery life changes.

Just closed whatsapp, that was apparently using 0.4 GB of RAM and the 2 youtube ones were using 0.6 GB :melting_face:

I still do have a lot of wakeups/second

And 60% CPU use, probably because of Chrome.
