My iPhone 13 Pro is still showing 100% capacity; and I got it on launch day. Do you use your MBP largely off charger and run it down frequently?
iPhones and MBPs are pretty different considerations. MBPs use several terraced batteries, for example, and are just much much higher wattage.

As for what might be wrong, a chap who is a battery expert above offered an explanation. In short, the most likely explanation is Apple's using old battery cells that have been warehoused for longer because of pandemic.

what's the bottom line here? should we go buy new MacBooks every year? what's the point of all this?

I usually keep them for a decade and replace the battery once. My 2014 and 2015 MacBook Pros are still going strong.
this thread makes me think at 94% after one year, I should sell my MacBook Pro get a new one.

It would be easier to just replace the battery. They charged $200 for the older models and you got a topcase, keycaps replacements. If they only need to replace the batteries on the new ones and replacement is easier, they might charge less.

I have a M1 16 inch MacBook Pro. How many days does it take? I dont like a hassle.

It depends on your Apple Store and whether or not they have it in stock. It was over the weekend for my 2014 and 2015 MacBook Pros. I think that they can do it overnight if they have it in stock. They apparently run a third shift at my Apple Store to repair PCs and phones. I always have a backup MacBook Pro if I have to take my primary in for service. My 2014 is on long-term loan to my son but I plan to sell my 2015 when I get the 2014 back.

I'm @ 98 cycles on my 14" with 92.4% health according to coconut. The reading varies a bit day to day though like ~1-2%.

Had mine since early February, I'm at 100%
Aaannnd not for the first time... Is that in Coconut Battery, or System Preferences/Settings? As mentioned a fair few times now, Apple lies about the battery health.

Here's my system showing the Settings app alongside Coconut Battery, which reads from the hardware.

That's in System Settings. I'll look into the Coconut Battery of which you speak.

if my MacBook Pro 16 inch m1 is at 94% how much longer until I drop below 90%? I refuse to have a notebook with battery health in the 80%s.

I think that I get about 13 hours or so out of my MBP 16 which is more than enough for my needs to use it without having to bring a charger. If I did need more battery, I'd probably get a battery pack - these are fairly cheap and can provide a good amount of power. If there were an AC outlet, then I'd consider a small USB-C charger. You could just pay Apple $200 to replace the battery when it drops below 90% but that's a lot more than a portable power bank.

Note though, that in order to get a battery replacement done, your battery health (using Apple’s diagnostics, not Coconut Battery) has to be <80%. Otherwise, they won’t do it, even though you’re paying for it. Mostly because the cost to them is quite significant given all the other items (topcase) that end up getting replaced when getting a new battery.

As @pshufd mentioned, it depends on the Apple Store, how big it is and whether they do MBP battery repairs on-site (and have in stock) or not / off-site. I did once for my older 2016 13” MBP, and also last year for my wife’s 2014 15” MBP (was showing 75% Battery Health and giving system notification to have battery replaced). Each time, I dropped mine off on Thurs afternoon, and got it back on the weekend (Sat or Sun).

Sounds like I need a second Mac? Might look into m2 air as a second machine.

MBP 14 bought shortly after launch. I am also not that happy about the fast degradation. My previous MBP 16 2019 battery was holding up much better. Tbf the battery capacity of the MPB 16 was bigger, so it wouldn't build up the same amount of cycles in the same time, but still a bit disappointing.

Heftig. Die Abnutzung Ihres Geräts innerhalb dieser kurzen Zeit sieht ungesund aus. Vielleicht Apple kontaktieren?

I‘m also concerned with how my 14 is doing, but not as bad as in your case 😳

My battery reading is now saying it has been charged to 100% even though I have "optimized battery charging on" and have unplugged the charging cable like 3x since I bought my MBP a month ago.

It was kept at 77-80% steadily for several weeks, any idea what could have happened?

Hatte ich auch schon überlegt. Hab zum Glück AppleCare+...

Yes, I am also concerned about it. Nonetheless, my plan for now is to worry a bit less (let's see how that goes) and just use it normally for a few more months, hopefully not giving a damn about the battery, and then check it again. If the drastic downtrend continues, I will definitely contact Apple and request an AppleCare+ claim.

what's the bottom line here? is battery health of 94% warrant trading in for a new one?

If it's plugged in most of the time, then it will only charge up to 80%. That's to increase the longevity of the battery. If you add the battery icon to the menubar, then you can click it and tell it to charge to 100% on demand. Completely normal starting in Monterey I think.

Is this true in Ventura? I can’t find this just an optimize button and my mbp charges all the way to 100%
