Why didn't Apple include a bigger battery? To prevent users from wearing the headset too long?

I think the leak you're referring to, including that 18Whr number, might be bogus. This doesn't even have the shape of the AVP battery pack:

Those are clearly bare cells without a BMS flex attached. The inkjet printing suggests two pouches would be connected in parallel.

This is referring to the cable coming off the VP that connects to the battery pack for power OUTPUT.

The power INPUT to the battery pack is, indeed, USB-C.

Sure, but we all knew that already.

The point we're discussing is swapping battery packs. It suggests the user can't just connect a conventional battery bank to the supple cable to extend run time on the go.

Just connect a portable battery pack to the portable battery pack.

It was always portable battery packs all the way down 😂

People are talking about the battery not being large enough, but then you can make it larger just by plugging another battery into it and it charges the device while the small battery stays charged fully -- then the battery pack drains and you can then put another battery pack in if you really need.

That hole in the shape of a USB-C port is a charging port -- and I am pretty sure I heard that it was USB-C but cannot find it now.

I don't know about you, but it's clearly different shapes.

If one is USB-C (input), the other isn't.

That’s the part that goes into the headset itself. It appears the battery pack itself has a USB C port. So you should be able to just plug a battery into the the battery pack.

Expect 3rd party pouches/belts.

I don’t see what the fuss is about here.

Well, that seems efficient. Use a battery to charge a battery. I wonder what losses are after double voltage conversion.

It does solve the “how do you switch power” on the fly problem. The Apple battery is going to preserve enough charge to prevent a full shut down (likely saving state even if the screens turn off).

Again, I don’t see a problem here.

Why would you need two in parallel? Seems like a waste of space. A 2 hour run time suggests a 0.5C discharge rate. You don't need to deal with the complexity of wiring two separate packs together and charge balancing them.

This also suggests that the power consumption on AVP is 9W, which seems rather low, no?

You should ask Apple, they seem to love parallel designs. Here's the MagSafe battery pack for iPhone.

Why wouldn't it do the smarter thing and pass power from the input to the output without needing to go through the extra conversion step? Why charge a battery from a battery?
 
I feel like the simplest answer would be that the 18 Whr rumor is wrong, and the headset consumes significantly more power than the rumors suggest.

Which is marked 7.42V, so those are in series to get a higher input voltage to the charger. It also has a big freaking Apple logo that indicates it's an Apple product. Neither are true of the pack you shared.

Because there is no guarantee of the voltage. It could be 5V, 9V, 15V, or 20 V.

Yes, I apologize the leaked photo doesn't have an Apple logo. It's a shame that Tim Cook didn't hold the pack on live TV to verify or deny the authenticity.

Is painting the logo on these the last step before final assembly?

You have a tendency to ignore the parts of comments... Like the voltage difference.

Why would suppliers apply a logo for a product under NDA? That's the last thing Apple would want suppliers to do. We've all seen the "Death Star" logo on the iPhone 4 prototype.

We don't know enough about how the VP works or the features. On the other hand, we have a known reliable leaker of Apple parts.
 
Doesn't look like a battery that goes into a battery pack to me. Looks way more similar to a battery that goes on in the headband of a VR set similar to the Meta Quest Pro Battery:

Battery - Hole for headband adjustment - Battery

I don't think this is an Apple battery.

Look at the list of bad design decisions you're attributing to Apple just to make this leak true...

Current rumors put the Vision Pro battery pack at 18 Whr. Why didn't Apple include a bigger battery to double the runtime? A 37 Whr power bank (10,000 mAh) weighs 200 grams, or about the same as iPhone 14 Pro/Plus. So it can't be because it's too heavy.

Whatever the true capacity is that translates to the two-hour runtime, I bet the simple answer is (a) so that it fits comfortably in your pants pocket and (b) so they can sell an extended battery pack with larger capacity as an accessory.
