How's the battery life on 14'' M1 Max (24GPU, 32G)?

[FactorialN]

Does anybody have this config (or similar 32GPU 32G)?
According to those claims from the Verge, I'm very worried about its battery life but I do want a smaller device with great graphics capability.

Im with you on that and trying to figure it out. For now my thread where i ask if the max draws more power than the pro is unanswered. I also did not find any reviews for the 14 inch with 32GPU cores. Seams like all the review units where 14 m1 pro and 16 m1 max. Luke Miani has a 24core but only testet the GPU performance. When i take the difference between m1 pro and m1 max on 16 inch into consideration i would say its less than 20%. There seamed something wrong with the verges test.

Hopefully someone with a actual unit will give us answers.

Good YouTube link here giving more definitive comparison between M1 Pro and Max , as well as 14 inch pro. Safe to assume 24 core 14 inch will be something like 7-7.5 hours of battery life with regular use, if you extrapolate based on the reduction of cores + the percentage decrease in the 16 inch model

I saw that thank you. It is a good answer despite two things. 64GB RAM and not one reviewer testet the low power mode. Maybe the apple implementation is so good that the mode does nothing but coming from intel laptops the low power mode was like 100% more battery because it boosted far to often.

FYI for those wondering - I just got my 24 Core M1 Max 14 inch in today. Been running it with regular use for about 3.5 hours and it's down from 100 to 62%. Extrapolating that out, you come up with about 8.7 hours of battery life. Definitely not bad.

I get a little less than that on my 24 core M1 Max 16' running word, safari, and occasionally apple music at low volume.

As i have my M1 Max 24GPU 32GB i can now deliver numbers. So my real question was, does the macbook use much more power during really low demanding tasks like websurfing and writing (with low power mode). My standard was my M1 Air.

The answer is ~16 Hours (20 was my max) vs ~20 (22 was my max) Hours on my Air. So i still dont know how much you can squeeze out of the M1 Pro but i can say that the 14 inch has enough battery life for me.

Some of you might ask why i have so hight numbers its because i do not use both my of devices in bright areas so my display brightness is always under half.

I have the 14” MacBook Pro with the M1 Max, 24 core GPU, and 32 GB of ram and confirm that you can easily get over 12 hours for lite task work. The biggest improvement in battery life come from:

• Running in low power mode (which basically reduces the screen’s refresh rate to something like 30hz)
• Running the screen below half brightness
• Quitting apps that use chromium (i.e. Chrome, Slack, etc…) I’ve caught Microsoft Edge using like 100% CPU in the background because of ads or JavaScript heavy web pages

From technical perspective, the CPU/GPU use power gating, so I would not expect ANY battery impact of additional cores what so ever. What is going to make (a minor) difference is the RAM, as you are bringing in additional chips with MAX.

So Apple have said there is a difference for what reason exactly? They want to hurt their own sales just because? There is a difference. It's just unclear what the difference is outside of intensive gpu tasks.

They've said M1 Max generally uses a bit more power because it's true, and they're not trying to misrepresent their product.

If you reread the post you just replied to, you'll find the explanation inside. To make it more clear, the more memory die there are and the more memory interface pins there are, the more power the system uses on memory. M1 Max always has twice as many LPDDR5 memory interface pins as M1 Pro.

timestamped. If there wasn't a difference... What's the explanation for this video showing one?

So are we in agreement that the m1 max's battery is worse than the m1 Pro if they both have 32gb ram?

Has anyone been saying otherwise?

 

[Serengeti1]

Has anyone been saying otherwise?

Yes. People are saying many different things. It's becoming incredibly confusing lol. The general consensus outside these forums is that the max has less battery life for all tasks. However, on here there are quite a lot of people saying it's equal, and that you'll only see a difference with gpu intensive tasks.

Battery life on M1X PRO vs M1X MAX?

Are all the machines in the four test 14inches? Otherwise we might be comparing apples with oranges. I ran the test 1080p video on safari with my machine that is 10c/32c/64GB M1 Max 14 inch and I've got about the same values, slightly lower, around 1400 mW package power, 700 mW DRAM. To me...

I think he meant in this thread.

 

[Serengeti1]

I suppose not. I'm just trying to find answers on whether there is a battery difference between the pro and max models if they both have 32gb of memory (outside of gpu intensive tasks).

Are you guys saying that the increased memory speed of the max is what eats at power then? I'm not familiar with a lot of the tech jargon. But to be honest, I'm not so much worried about what makes the difference. I'm just trying to confirm that there is one and am confused as to why people are now saying there isn't one.

 

[ksj1]

I think it's kind of obvious that a pro will use less power than a max, even at the same load. The max has a lot more silicon to power than the pro, even with gating you have to keep all your memory going, there is a difference between the pro and max there, as has been noted. And there are additional media encode/decode complexes. All of this takes a bit of power, even when not in use. After all, the user expects it to work pretty much instantly.

Of course all of that will take more power. I mean, there are 23+ billion more transistors in the max. Not understanding why this is even a question.
