stunned but what is the battery life your getting... people keep saying its good but not telling times lol
For the 14" owners, what's your battery life like so far?

This is how you have to use the MBPs to get maximum battery life.... at 50 nits it will last for hours and hours!

Ok, I'm a little confused. Yesterday my battery life was pretty good—probably about 10 hours. Today, I've only been on battery for about 3.75 hours and I'm already down to 39%. And my work has been very light. Just a 45-min Zoom call and then web browsing, email, etc.
That said, I've noticed that "Core Sync" has been listed in the "Using Significant Energy" area in the battery menu. That is related to Adobe Lightroom/Photoshop, but all of my images are synced and neither of those applications has been open for more than 10 minutes today. Brightness has been even lower than I usually have it, probably 10 clicks to the left.
Any ideas why I'd see such a huge difference? I'll be lucky to get 6 hours today. Doesn't make any sense.
UPDATE: Just found this article about MacBook Pro users having issues with Core Sync using a lot of CPU. However, I think disabling Core Sync means my images won't sync to/from the cloud to/from Lightroom, which isn't a good solution.

This is why I do not support the 14. There are varied results on the 14 battery. Not sure if your situation above is caused by issues or if it's just the 14 acting normally.

Yes, it's disconcerting, for sure. If this continues, I'll have to return it and keep the M1 Air I have, and maybe wait for the M2 Air next year. I can live with 10 hours of battery life, but not 6.
I just charged to full again and will test another cycle.
I was checking Activity Monitor and noticed that Brave.app was at 125% CPU for a good chunk of that time when my battery was draining. I restarted the MBP and now Brave is acting better. So, we'll see.
I know this shouldn't come as a shock, but i think a lot of it depends on what programs you use, and whether or not they're optimized. Microsoft Teams (not optimized for M1) in particular chews up battery for me. I have the 14" M1 Max (24 Core 64GB), and I'm down to 40% after ~3 hours of use doing the following:
Zoom video call - half hour
Teams video calls - hour and a half
heavy spreadsheet + database work
Since I finished the video calls, my battery percentage hasn't moved in about 20 minutes. Hopefully this is helpful to someone, but happy to answer any questions or provide additional data points.

The only app I have that isn't Apple Silicon optimized is Dropbox.
Zoom is supposed to be, but I've noticed a much bigger impact of Zoom calls on the M1 Pro battery than on my M1 Air battery. Maybe because of the better display and webcam?
Otherwise, I can't really account for it.
For things like Brave app you could try App Tamer; it prevents apps from using too much CPU.

6 is unacceptable. Honestly, 6 hours of battery with these new silicon chips is a travesty and deserves to be trashed.

I have a 14” but my battery doesn’t last long enough for me to comment on how-

I just started on a new charge this morning. We'll see how it goes. I'm not using Low Power Mode yet because I still want to get a better handle on how it performs with normal power.
The other day I think something weird was happening with Brave.app or Core Sync that drained my battery way faster than usual.
Battery Health 2 is telling me that I have 11:41 remaining on this charge, with brightness set at 8 clicks to the left. I'll report back.
Tomorrow, or Monday, I'll then do a test in "low power mode". I'm motivated to figure this out because my last day to return this to the Apple store is Thursday of next week.

Monterey is currently facing a memory leak etc. Real-world tests here last me around 20 hours with idle at lunch break and coffee break. I have the 14" M1 Pro that doesn't eat battery as M1 Max does.
How I measured, I look at the battery drain graph and each bar is 15mins and the chart is the last 24 hours.
Wait for Monterey patch or kill the memory leaking process.
Also, don't use Chrome. Get Firefox or Safari.

Does anyone know if Brave.app suffers from the same power drain/memory issues as Chrome? I was under the impression that it didn't, and I never noticed this before on my M1 Air. But that might just be because the battery life is so exceptional with the Air that it didn't matter.

Got 6 hours light use yesterday from 50%. Plenty happy with that.
Was sat at the kitchen table doing research for a report. So lots of safari, taking notes in notes, tunes on in music output over airplay, probably an hour procrastinating on youtube across the day, a few emails, a few messages etc etc. All the apps I was using are m1 optimised which helps no doubt.
Anything more intensive would use battery quicker of course, but then I'd very likely be sat at my desk to use the monitor so ?♂️
The battery performance of the (lower powered) Air and 13" m1's seems to have skewed expectations a little imo

Was Lower Power Mode enabled during this test period?

Nope.

Yes please report back how much difference low power mode makes. As my M1 Air was new it would also get pretty bad battery life. Was a combination of not optimised programms and the device indexing stuff / bugs. With Monterey being that buggy it would be better to get a whole hour of "good" usage on low power mode and interpolate the rest.

According to Battery Health 2, I've been on battery for 2:03 (battery preferences tells me that 114 of those 123 minutes have been "screen on" time). Battery is at 93% still with an estimated remaining time of 12:49. Apps I've had open/used during this time:
If I continue to get battery life like this, I'm happy. But I still am not sure why I got such terrible battery life the other day. It has been really inconsistent, which makes me nervous.
- Brave
- Spark (email)
- Slack
- Powerpoint (have used most of this 2 hours)
- Things
- Roam Research
- Fantastical

It can depend on Photos or Spotlight indexing or similar if it's new for you. Always dock your new laptop for 12h during night so it can fix everything that needs to bee fixed. Maybe it was still syncing with iCloud or Time Machine etc.
OneDrive sync can also drag som batteri at first sync etc.

Yeah, I'm aware of that. I set the computer up on Saturday when I picked it up from the Apple store. Yesterday was the day with really poor battery life, and I'd used it every day since Saturday. So it doesn't seem like it would have been a sync/set-up issue.
I did notice that Brave.app was hogging CPU unusually during that battery drain time. After restarting, that's not happening anymore. So I'm hoping it was a temporary issue with Brave or one of the sites I had open.

As mentioned i had the same Problem with the Air when it was new. I searched every forum for a reason why reviewers got 15 hours and i only 7 but after 2 weeks it was great. On very light load i had 20 hours. Maybe it was an os update. When it lasts one time as long as it did it will be the default.

Well, if that's true it's a good sign. I'm at 85% after 3:36 on battery and 2:50 of "screen on" time. Battery Health 2 tells me I can expect another 11:26. That would be over 14 hours.
Again, no Zoom or video calls today or anything intensive. But even if that 14-hour estimate gets cut by 20-30%, I'd still be satisfied.
