I don't really think comparing the M1 Pro or M1 Max to the regular M1s in terms of battery life makes much sense.

M1 Pro/Max CPU=> 2 efficiency, 6 or 8 high performance | GPU => 14 core to 32 core
M1 CPU => 4 efficiency, 4 high performance | GPU => 7 or 8 core

If you are buying a 14" or 16", you are getting significantly more power thus expending more energy and reducing battery life. Not to mention the updated displays etc

I'd assume people are purchasing these M1 Pro/Max laptops with a reason justifying that purchase & understanding why the battery life is going to take a hit. Maybe you need the extra performance that the M1 doesn't offer, maybe you want the better screen, maybe more ports, maybe the ability to natively connect more than 1 monitor or all of the above!

The way Apple has the laptop lineup now makes sense. Base M chips for most users providing great performance and great battery life. Pro/Max M chips providing power users with exceptional performance and average battery life. There are always going to be compromises given one's own use case
A few of us are interested in normal web surfing battery life between m1pro vs m1max (14inch) thanks !:)
 
I'm 14" M1 Max, 64gb RAM, 32-Core GPU, 2Tb.
I'm at 6h 30m on battery today, brightness 2 memories less than maximum.
Bluetooth on,Wireless Web,Desk work only (no video or image editing)
Note that most of the battery tests were at 250 nits, which I believe is 8 clicks below maximum. One reason why you may be getting lower battery life is that you are close to maximum brightness.

But, this does match pretty closely with what I posted earlier. If some of the testers only got 8:40 watching video, then we'd expect only about 6:30 with wireless web browsing and desk work.
 
Yesterday I was able to order a 14" Pro base config and pick it up at a nearby Apple Store. I had originally ordered a Max, but after reading some of the battery reports, I think I will return it and keep the Pro. It is PLENTY powerful enough for my needs, and although we don't have rigorous tests yet, I've seen enough reports to convince me that the Max battery life is likely to be at least a little worse than the Pro.

First overall impressions:
  • The size and weight difference are definitely noticeable vs. my M1 Air. More than I expected. I'll need to live with it for a few more days to see how I feel about it.
  • This is by far the snappiest Mac I have ever had in >30 years of using Macs. It just flies, even relative to the M1 Air. Very satisfying experience.
  • The screen is amazing and so are the speakers. HUGE improvement coming from the M1 Air.
  • The webcam is incredible, and SO MUCH better than the M1 Air's.
As for battery life, I'll report back later today. But I started using it about an hour ago (lightly), and it's still at 100%, so I think it's going to be fine.

Somebody has 10 hours on a 14inch m1max 32gb ram - anybody else with similar setup can share their battery runtimes? Thanks!

That probably seems about right.

My last charge on a m1 pro 10/16 was Thursday.

I've ran for around 8 hours, with 25% battery left which is approx 2-3 hours.

12 hours seems like the norm for mixed use for the pro chip. At least for me.

This seems very close to what I am getting with my 14" Pro 16 GB.
 
Update. In my very unscientific test, I'm at 50% about half-way though my workday.

For comparison, with my M1 Air I'd probably still be at 65-70% at this point. So, the battery life of the 14" Pro is noticeably and significantly worse, which of course is not a surprise.

One caveat is that I opened Lightroom for the first time on this device and it downloaded 7,500 images. I saw the battery go from about 85% to 65% quickly during this process.

The battery report is showing about 4:15 for on-screen usage. So, at this rate, I'd end up with only about 8-9 hours, which is less than expected. I'm hoping that once everything is downloaded and set up, it will be better.

Unacceptable. Design is one thing but taking multiple steps back on battery life? Come on Apple, you can do better. I’m not asking for M1-13 like battery life which is the best, but something close to the Air?

Just remember he was processing a lot of LR images.

The first few days with my new mbp had reduced battery life due to background processing.

I also own the M1 air and it’s about 25% more.

I believe the 16” is about this again. Maybe a touch less.

For a pro machine with a bigger screen, more memory and more performance cores 25% less than the M1 air probably about right.

Yes, exactly. I will report back after a couple more days when I'm not downloading a bunch of images or doing setup stuff.

I expect it will be, as @bp1000 said, about 25% less than the M1 Air, but I can live with that for the better display, webcam, audio, and performance. (As a small bonus, the keyboard is an improvement as well.)
 
I will say that, since I finished downloading those images, the drawdown on the battery has been much slower. I'm still at 44%. So, I think I should likely get better battery life tomorrow when I'm not doing that.

For reference, I had a sync issue with Lightroom on my iPhone 13 and had to re-download those same 7,500 images, and it took me down to @30% battery. Normally, I'd be at 70 or even 80% at this point of the day with my iPhone, so this supports the idea that the major battery hit was due to Lightroom downloading images.
 
Just starting my day on my 14" Pro. No plans to do anything abnormal, like download 7,500 images in Lightroom, that would impact battery life. I'll let you know how it goes.

It was so much longer than my last test, could it be due to the low power mode or the screen brightness?

Brightness makes an enormous difference. Not sure about low power mode, someone else would have to weigh in there.

When you say "I'm at 9h 00m", does that mean that's when you're battery got to zero? Or are you still going?

I've been using a 3rd party app to monitor battery life. Is there a way to get exact time on battery with the Mac OS battery pane in system preferences? When I click on Usage History, all I see is a chart with bars (which only makes rough estimates possible):

Screen Shot 2021-11-02 at 7.19.17 AM.png
 
Notebook check has a review out. Battery life for the 14” is pretty solid depending on what you’re doing. The M1 MBP does have longer battery life but again not as full powered and a display incapable of HDR, etc.

seems more than enough for a typical workday if away from the desk (and again up to 50% with 30 minutes plugged in)


“The runtimes with the 69.9 Wh battery differ massively depending on your usage scenario; we got everything from one hour during the stress test all the way up to 15 hours video playback (SDR at 150 nits). Our Wi-Fi test (Safari, windowed, 150 nits) runs for 13.5 hours, but only 6.5 hours with the maximum brightness of 500 nits. Playback of an HDR video at max. brightness in full-screen mode only runs for about 4 hours.”

I've been on the battery for about 4:15 today, and I'm still at 72%. That's a good sign. My activities:
  • Web browsing with Brave.app
  • Email with Spark.app
  • Slack
  • A few short movie exports in iMovie
  • Working on a presentation in Powerpoint
  • Spreadsheets in Excel
  • Other apps: Messages, Fantastical, Roam Research, Things, PDF Expert
Not much Lightroom or Photoshop work yet today. One thing I've noticed is that every time I've clicked on the battery icon in the menu bar, it lists "Core Sync" as an app that is using significant energy.

Core Sync is part of Creative Cloud. I do sync my photos across devices for Lightroom use, but they are all synced and backed up right now, so I'm not sure why that process is still running and consuming significant energy.

I have a 14" 10-core Pro 16 GB.

Wow, look at the difference when brightness is at 150 nits (13.5 hours) vs. max brightness (6.5 hours). I wish more websites would disclose the brightness level of their battery testing.

Then don't buy. I think what Apple did here was incredible. Is there a laptop on the market with this sort of performance and battery life in a three and a half pound 14" shell? You'd be lucky to get 4 hours out of the Razer Blade 14.

I believe 150 nits is similar to Apple’s settings and they quote 11 hours so seems they might outperform their web browsing numbers while video seems in line.

MobileTechReview just dropped the 14” review and got 11 hours of routine regular use at 200 nits with Safari tabs, etc. which is pretty solid, and ~5.5 hours of Final Cut Pro editing which is far more demanding. Outlier use cases aside, I’d imagine those runtimes plus fast charging should be sufficient for most heavier users.

The battery usage history shows 6.5 hours of "screen on" time today, and I'm at 31%. Estimated time remaining is about 3 hours—but I won't get there because I'm nearing the end of my workday. And I guess that's kind of the point. If this thing can last for more than the duration of a full work day for me, that's enough.

The battery life is clearly worse than my M1 Air, but I knew that going in. And for me, the improved display, speakers, webcam, keyboard, and the insane performance are worth giving up ~2-3 hours of battery life—especially because I can charge it to 50% in 30 minutes.

One thing I did notice today is that the battery drain sped up quite a bit after a few Zoom calls that I had. I didn't notice that as much with the M1 Air, but that may be in part because the battery life on that is just so good that I never even paid attention to it.
