I was genuinely curious if Low Power Mode will make a significant decrease in performance in achieving better battery life.
For anyone curious, here are some raw data from Geekbench 5 I conducted today on my M1 MacBook Air on macOS Monterey 12.0.1 (256 GB SSD/8 GB RAM).

Low Power Mode:

Single Core: 1069 (~37% decrease)
Multi-Core: 4389 (~40% decrease)
Base Frequency: 1.95 GHz

Normal Mode:

Single Core: 1703
Multi-Core: 7400
Base Frequency: 3.20 GHz.

Wonder how this will translate into battery life.
I suspect for daily office-tasks, streaming and consuming content, LPM will still be more than enough.

Forgot this was even a thing. Gonna turn it on and finish my week and see if I notice a change
Please do, I'm curious as well and will be doing the same. I do wish they at least coloured the battery to yellow-orange like they do for iPhone and iPad in case we forget we have it on.

Your low power mode is still faster than my 2017 iMac Core i5-7600 at full speed. This machine scores approx. 1000/3500. Performance for daily office tasks and media consumption is excellent.

I also have a 2010 iMac Core i7-870 which scores about 600/2200. It can occasionally lag here and there but overall I would classify its performance as very good for such tasks.

Now that is insane!

I had forgotten this was a feature in Monterey until this thread. Just turned it on. We'll give it a go and see if it makes any noticeable difference in either basic performance or battery life.

How is everyone with Low Power Mode on?

I find that I maybe get 30 mins to an hour more under my usual workload (Zoom, a couple Word docs, GoodNotes 5, and PowerPoint).

I don't notice any sort of performance slowness.

Have you guys noticed a significant increase in battery life, performance decrease?

I forgot it was on until this post reminded me. Zero performance difference at anything that I tend to use it for. Battery life up about 10% longer. Overall would recommend. Havent tried it for my 3D stuff yet though

Just leave it on for a few years and then suddenly remember it exists to make your mac feel like brand new
We used to do this in cheap cars, years ago. There was a Turbo button. When you turned it off, you got "turbo speed". ?

Just following up.

I do notice a bit of performance hit when I am exporting and doing basic video projects using iMovie with Low Power Mode. And when I mean a hit, I mean it might take 10 seconds more to export compared to when low power mode is off. When I am web browsing, Safari or Chrome, there is no performance drop from what I can tell. Battery life, I may get like, 30-40 mins more? It's hard to tell.
