High power consumption on a Thinkpad T480s with F34

Hi all,

I just noticed a higher power consumption with F34 workstation on a T480s. Anybody observed the same behavior? According to powertop the consumption is around 6.5W when it’s idling, and when I’m surfing the web and doing some work in VIM its approx. 7-9W. For me these seems high, if I remember correctly I got around 4-5W during idle with prior Fedora versions. Additionally, I also have to charge the battery more often, which fits to the higher power consumption. Any ideas or comments are welcome.

My only idea is that the power management utility tlp might help. However, on my HP notebook, it caused major instability (frequent system crashes).

Loot at this:

It might help.

Hey -

I`m using Fedora 34 Gnome 40 on a ThinkPad T450.

On a full charge watching Youtube, it only lasts for 40 mins to a hour.

Tlp did not have any effect on battery life, so i removed it.

On another forum they recommended “Power-profiles-daemon package”.

Now it`s better than it was. The indicator says 5 hour on standby, but when i use Youtube it drops down to 1h 15 min when on “Power Save Mode”

Are there any way to get better battery life or am i too demanding and 1h 15 is ass good as it get?

I don’t have experience with the thinkpad, but in general battery life is mostly related to cpu speed on laptops. Many, mine included, limit cpu freq (speed) when on battery. That usually however can be controlled from within bios to set the power profiles. Mine has power save, standard, and performance profiles and with the performance active it allows the cpu much higher speed and much less battery life.

Try checking what your settings are.
