Apple M1 Performance and Power Consumption in Low-Power Mode
Вставка
- Опубліковано 2 сер 2024
- After Apple announced low-power mode would be available in macOS, I was interested to experiment with it to see what performance and power usage changes there were when using it. The results were quite interesting. While there are quite a few videos out there with M1 Pro and M1 Max-based MacBook Pros being tested to see how long they run on battery, I haven't found a video discussing it in the original M1, let alone the fan-less MacBook Air! Well, here ya go! Enjoy!
Note: Geekbench results were from a set of runs a few days prior of the date shown as I had to record a second take due to audio issues.

very high quality test... and i've watched nearly 50 previously on these m1 macs
Thanks, very useful and well explained!
I wouldn't recommend LPM if you work with a digital audio workstation. I noticed performance issues in Logic Pro, which makes sense as audio effects need more "peak" power and less continuous load than the usual CPU-heavy task. If the CPU can't deliver the performance needed, audio will stutter or stop.
As soon as I plugged the power supply, everything worked perfectly again (and I have to say the M1 chip handles heavy Logic Pro X sessions extremely well).
PS: I thought the video was a bit long if you're just looking for the bench & energy saving results. Maybe add a quick recap at the end for people who are just looking for that? It was interesting to see how you conducted the tests though.
this was so well demonstrated
Thank you, I never knew about this _'low power mode'_ until recently, so now I can enjoy the benefits of better battery endurance with the knowledge that I can turn the mode off again when I need better performance.
Thanks, this is great info.
Nice video bro. Needed to know if I should keep it plugged in to play games.
This needs to gain more views
this convinced me that low powere should be off unless i'm really trying to squeeze in almost 2 more hours of simple tasks... great vid.
In my experience, I tried a game with and without lpm, and it showed quite interesting results. Though no lpm gives me higher fps at first, it throttled soon and the performance after that is mediocre at best. With lpm on however, throttling happens much later(if at all), meaning frame drops are not as often, but do need to sacrifice (in my case) resolution for a smoother experience.
nice one
This is the best video ive seen on this topic. Ive been looking forever for M1 MacBook Air focused low power mode, so thank you!
However this video focused on how efficient the M1 Air is in terms of power to performance ratio. However, I really wanted to know on a day-to-day basis for things like browsing on chrome, email, youtube videos, spotify etc should you enable low power mode? I dont think efficiency cores will kick in for those activities right.
so does using low power mode give us a better battery life and if so how many hours ? this is what i wanted to know!
I discuss it toward the end of the video. Thanks for watching!
Great video, thanks. I'm curious if there is any downside to leaving the computer in low power mode all the time if you aren't doing any heavy tasks. Is it "hard" on the efficiency cores? Seems like if your use case is just web browsing, email, typing documents, etc., this would be a much more preferred setting to maximize battery life and keep temps cool.
Thanks! In the video the temps on the efficiency cores didn't get very warm. And remember, like I said in the video, the performance cores are still able to run, albeit at a much lower clock frequency. So, I don't think it will cause more wear or anything like that. 🙃I don't feel the need to have it on all the time, as macOS and the M1 SoC controller does a pretty excellent job of managing itself.
Hi, for a comparision, LPM does use 50% less power consumption than standard mode?
Also, does LPM activate some kinda of bad and aggressive "PWM" frequency to the display brightness? I've noticied the screen brightness to dim when LPM is enabled.
For the first part of your question: Did you watch the video? 🙃
Second part, as far as PWM, I notice no change when it is enabled vs disabled. The screen brightness doesn't even change. The only time it does is when it is plugged in since I have "Slightly Dim the Display While on Battery Power" enabled. Hope that helps.
What is the heat output when you stress it out while in low power mode? Does the SoC still get close to 100 degrees Celsius? Despite the fact that this is not an intel system and it's more efficient and yada yada, I'm still very worried about heat damage in the long term.
Around 40 - 50°C at room ambient of 20°C.
Thanks for the video!
Give a damn conclusion!
You should be capable of concluding yourself if you watched the video
is low power mode enogh for streaming youtube videos? thanks Sir.
Of course, it'll still be just as fast in general tasks in low power mode its only for intensive tasks that you'd need to enable it again other wise you won't see a difference.
Streaming UA-cam videos is pretty much all handled by the GPU and dedicated decode blocks for VP8/VP9, etc... In the video I show the relative performance difference of the GPU when it is in low power mode. To the point @Ahsoka made, you really won't notice the difference, for general tasks. So, TL;DR, it's fine for UA-cam videos.
No wonder my protools would crash all the time
That might cause it! If Protools is running in Rosetta, the power limitation on the performance cores could significantly impact real-time audio processing like that!
