Has anyone tried running any benchmarking tests under Low Power Mode on Monterey?

Apple says it will reduce brightness and system clockspeed. I assume any benchmark would be lower (pardon me if I’m completely off here) compared to when it’s not running LPM, but am wondering by how much.

Looking for any M1 benchmarks under LPM.

There are a considerable difference in low power mode, the CPU runs at just 2GHz! Geekbench result in low power mode below for reference.

How do you enable low power mode? I read that there doesn't seem to be a way to turn it on.
It’s in System Preferences > Battery > Battery (on the left hand seenu).

I definitely recommend Apple to make that setting more easily available.

Ok, wow. That is a significant difference in performance. Now I wonder how that translates to battery life.

Weird, I swear it was there when I briefly installed it on my M1 Air.

This is what that menu should look like.

I wonder if anyone will notice a battery life improvement over this. If not easily indicated (colour indicator in the battery icon on the menu bar) by the time of public release and someone later forgot they turned it on, they might start complaining on why their Mac has been so slow.

As it shows to decrease clockspeed from 3.2 GHz to 2.0, the performance hit should be somewhat noticeable in heavier applications in M1 Macs.

I’d be surely interested in some YouTubers testing this out.

There is an indicator when you click on the battery icon in the menu bar. It says 'Low Power Mode enabled'.

I'm really looking forward to this mode - not for battery life, but more for when I'm casually web browsing or watching videos with it on my lap and I just want it to run as cool as possible.

Agreed.

Moon, and safe from the ban
just testing low power mode on my macbook pro m1, 45 minutes screen time browsing on safari with brightness 5 bars, battery still 100

edit : 1 hour mark still at 100
