2:56 Thank you iFixit for talking about PPD, and measuring the the actual display resolution!
It is equivalent to sitting at around 3 feet / 1 meter distance from 50" FULL HD (1080p) TV. Quite impressive for a wide FOV VR headset.
It's starting to get in the screen replacement category!
I measured my visual acuity at 90-100 PPD. So once I have 8k^2 per eye and keeping the same FOV, pixels won't be an issue anymore :D
The high res VR panels race is now truly started, best current released HMD resolution is the Varjo XR4 (3840 x3744 per eye, marketed as 51PPD)
Looking forward to learning the central PPD! Varjo XR-4 has a central PPD of 51, and an average PPD of 34, the same as iFixit's estimate. Oh, hmm, how did they come up with 34? 3660/100 = 37.
But I think 100º horizontal FOV is for both eyes, so we really need the per eye FOV. If the binocular overlap is similar to Bigscreen Beyond (~80º) then the per eye horizontal FOV would be 90, which would give a PPD of 41. If the overlap is similar to Varjo Aero (~70º) then the per eye horizontal FOV would be 85, which would give an average PPD of 43.
@@mikeyr5275 i remember the overlap is really good, as good as Pico4 if not more, so I will put it above 90. Plus some degree of left and right, that gives one eye fov 100+. To get 34PPD is 3660/34 = 107.6 degree. That not too far off.
For anyone wondering. Apple aims for 120ppd in all of their retina devices. It's where most generally become unable to see details between degree of vision.
The apple vision pro being below 60ppd means we have a long way to go
I honestly thought this would have been a 1 or a 2 on the repairability score
The main parts most likely to break are actually easy to fix.
I mean😂 there are pieces you can fix. The only thing you can't is the plastic front cause let's be real, even if you wanted to repair something behind the glass, there's no way you could do it. Best we could have expected is to replace the straps and eye seal, which we got, as well as the plastic front, which we did not get. I don't think it is reasonable to be expecting to repair any internals like the M2 chip or anything like that
@@derickd6150 why shouldn't we expect to be able to replace what's probably one of the most expensive components in the device? The board that M2 and R1 chips are sitting on is fairly modular, nothing is soldered. Yes, there are lots of screws and connectors to keep track of, but other than that the only reason why internals can't be easily replaced is that Apple decided to glue down the front glass/display. I expect that adhesive is needed to mount a smartphone front glass because of IP ratings and the device being constantly squeezed/bent in people's pockets, but Vision Pro is neither water-resistant nor expected to be constantly bent so the decision to glue everything down is just frustrating.
Exactly, so they are even more repairable than could be expected. I would say 4/10 is actually quite low
Hundreds of screws, extremely modular, almost no glue. Extremely repairable, if one would get the parts.
I know it was provisional, but that 4/10 score was something I really wasn't expecting. If the glass was easier to come apart I could understand it but, looking at all the teardown vids posted online it looks like a maze!
For real. Giving a 3500 device a 4/10 when you genuinely need to open it with a hammer and chisel like a geode is... Crazy.
@@Jallen262 It's because everything is super modular, the spacial speakers, the head bands, the light seals, battery, etc. Those are the most likely things to die or need replacing. The front glass is as repairable is more replaceable than most front glass units on any phone since you just need to pop off the glass cover and pop on another.
@@SkaterStimm it's called the repairability score, not the modularity score for a reason.
@@Jallen262 dude, the more modular it is the easier it is to fix. The battery on most consumer devices is super hard to replace and look the battery is not even in the device reducing the need to open it.
i mean the things normal ppl would like to replace in case of damage or are all easily replaceable without even opening the device. and a lot is still rather accessible through the back which is just clipped in. so even motors and displays look rather accessible.
the only things that are difficult to replace are the front glass and screen and just the complexity of the inner construction. which tbh is hard to make easily accessible considering the sheer amount of different sensors
The Vision Pro battery pack can be opened without damaging the external metal. There’s a TH-camr named “phone repair guru” who was able to open the battery pack without damaging the case using acetone to dissolve one layer of adhesive and then using a pry tool to open it
Info it really need to do their research before publishing these video.
Yeah. He is not rich enough ti break it
@@kjeldkaj They were doing their own testing. Letting them know about more ways of trying to solve these issues is huge in the repair community so that comment is the best way to let them know about it.
Yeah we broke the battery. Our HMD went back together in working order though so yeah.

Consider proofreading your comments criticizing people. @@kjeldkaj
7:26 the Pro Vision-al score never made more sense than now!
Would've been a great way to end the vid
Using the Screwdriver case as a project box is both something I never considered and delightfully brilliant
The most common definition for "4K" is 3840*2160, the resolution of "4K" TVs or of "4K" movies, also known as Ultra HD. It's four times the pixels of Full HD. If the Apple Vision has 3660*3200 pixels per eye, that's not the same resolution as 4K, but overall it amounts to even more pixels, 29% more.
Though it should be noted that these pixels are distributed across the whole field of view, and some will also be cut off at the edges or possibly lost to software image distortions to balance out lens distortions. So if you watch a 4K movie in the Apple Vision Pro, you are only using a fraction of the FOV and of the pixels available in the display, which means the movie will very likely render with (significantly?) less than 4K resolution.
Not a big deal at all. You can’t see the pixels when watching content and that’s what matters.
Yeah it will be more like 1080p if you watch it how directors (THX standard) optimize viewing angle of films, similar to sitting in the middle of movie theater.
Resolution doesn’t matter, pixel density and pixels per degree matter. Regardless, even the low resolution of the quest 3 (2208p) looks perfectly fine so I expect the Vision Pro with a higher resolution and smaller fov to be incredibly sharp
Are Apple suggesting that it’s like watching 8k because they say it’s 4k in each eye? After watching this I’m gathering that you don’t add the two together..
@@fayenotfayehow resolution doesn’t matter. Whole field of view is covered by just 3600x3200 pixels so even if content window covers 50% of total FOV, actual resolution is even less than 1080p and rest of pixels are used by pass through.
It is amazing how many teardowns I have seen where people are cutting the cloth and not picking the clips like you did on day 1!
Fantastic breakdown.
Extremely high quality videos. Love this channel!
As someone who loves to fix their own devices, your videos are always interesting. I enjoyed the details and highlights for the devices.
Repairing this device would seem like a nightmare, but the removable cable on the battery pack, the removable head straps all seem in good faith. Win some, lose some. I saw @AppleTrack doing an impromptu durability test and he broke the speaker bands first, but glad to see those are replaceable.
Thanks iFixit Team!
Excellent teardown as always, thx iFixit!
Honestly guys: longer videos. This kind of thing deserves it.
I watched 3 videos on the breakdown this is by far my favorite!
*Try this. Connect your Mac to AVP, then check if you can select a different resolution in your Mac.*
I don’t know what people expect, actual reality? God made reality, we’ll never top that. Apple Vision Pro is the best we have right now.
2:39 grain has nothing to do with insufficient resolution, but rather with the input cameras exposing for light. A higher resolution leads to more noise, not less.
Thank you ifix for the 3D battery pack extender.
thank you 😊 ❤
Love yall!
Great review, thank you!
Awesome details & Info :)
Very interesting video! Thanks
its definitely nice to see the parts most likely to break have (almost) toolless replacement, even though they're all proprietary
Thanks for the honest review!
Nice video. Good job, guys.
It is sooo integrated that even having some user swappable modules will be surprising.
the battery pack being separate on its own gives the device more longevity.
I am concerned about that front and internal glass though.
Good info
This is a much better video than the first one.
Thanks for actually calculating the resolution
awesome video
They should get rid of the front eye display thing. Nobody who looks at someone wearing a VR headset cares about seeing their eyes. Apple could have saved weight and money by not doing that at all.
you can remove the glass with the plastic diffuser and front oled panel as a whole unit
Cant wait for you to get your hands on the new Brilliant Labs ar glasses next
Love it!!!!!!
0 plans on ever touching the Vision pro but am kind of interested on how you guys got the battery working
When you film the display you may get aliases with the spatial sampling frequency of the sensor, in addition the samples not being simultaneous, I.e. no global shutter, neither in the display chip nor in the camera sensor.
Just imagine the resolution of the screens in the future with micro pixel fabrication. Those pixels are dang so tiny compared to the iPhone pixels. Mind blowing!
That score seems very generous. Based on what I've seen from these 2 videos, I would have have said 1 or 2.
How is the front glass not repairable? Is it the adhesives? I would imagine a new part plus calibration would be suffice.
Can u take screenshots in this there I will get the correct resolution
i would like you guys to weigh the various components.. in particular the front glass panel and the lenticular lens and the front-facing screen. The reason is I would like to know how much weight those components add to the overall weight of the headset.
I would also like to know if the headset will still work if you unplug the front-facing screen and how much energy it draws. I suspect the front-facing screen is drawing about 10-15 Watt hours.. and if so.. removing that could potentially double the number of hours the headset could operate with the battery?
4 out of 10 sounds generous, considering all i can replace and fix is the headband with speakers, and the face cushion...
everything else is pretty much glues and sealed in a way even the most experienced repair engineer will likely damage the device
i am 3d printing a 1:1 Clone it will have some working stuff on the headset
FINALLY!!
any theories on why the battery cable has 24 pins?
Meta Quest 3 - 4/10 and it was teardown without structural damage and this too, very strange...
The Vision Pro had a modular design so it makes sense
This guy has the most unusual way of enunciating words. Never heard anything quite like it.
Can the vision pro external battery basically be used as a nice portable Apple-made powerbank to bring with you when on holiday? 😂
What is the heaviest part of the hardware?
Do these goggles have a rice cooling or passive cooling?
This is indeed a very cool product, but I would like to know if you feel tired or uncomfortable after wearing it for a long time?
i wonder where the h2 chip is
considering the battery pack is already external I dont think its as necessary that it is easy to open.
What part makes this headset so front heavy, in your opinion
Man that custom battery pack would be AWESOME!
For what? Apple to make more money? I couldn’t agree more 😂 Please just buy an off brand battery pack instead of this grubby company -Another Apple user
When watch a movie inside vision pro, I believe it's 4k per eye on a like 1500 inch screen?
2:39 "...grainier than other devices?" What does that even? And what are you comparing it to?
Honestly, it's way to early to see where this product goes to really determine if it's repairable. I don't know if it could be made more repairable without making it heavier, but it clearly could pull the same trick for the light shield with the front screen.
But I also expect future models based on M4 might actually forgo the front screen entirely. Sure it's kinda neat but it's also of no actual benefit to the user and burns battery life.
Why use two panels vs one large one? I rewatched Ready Player One and noticed when Wade puts his VR set on, it had a curved oval shaped display.
It’s not the hardware that makes it 3,500 but rather the cost of R&D spread among a limited production run.
All that hardware is also expensive though.
did u not see the teardown video ? the amount of tech they have cramped is crazy difficult
The HTC vive is built better and harder for WAAAAY cheaper than this plastic pos
I can buy 2 entire HTC vive setups for the price of one apple vision pro with money left over.
@@mickey_mousey considering the displays are $700 for the pair considering the bulk pricing they got for that price to be real, is insane to only be 3500 when something closer in spec to it is $5000 from varjo, not a fan of the apple vision pro but the tech they managed to use for the price is insane.
They just got to amp up the speed into Terahertz to get rid of the display lag...
4:46 Not necessarily. That 35.9Wh rating is at 13V while the 46.08Wh is rated at 3.87V. Boosting the voltage induces more heat loss, therefore the lower rating.
I don't think they're boosting the voltage. I'm pretty sure the 13V figure is the max voltage expected from the three cells wired series. It looks like Apple is using high voltage cells which can charge to over 4.3V each cell.
Note the "nominal" voltage isn't the same as "max" voltage. The 3.87V figure on the cell is nominal voltage not max voltage.
battery is in series , no booster needed.
Great breakdown, and you didn't need to destroy every single piece of the device...
Sacrifices must be made.
I need same things but no pro
Phone repair guru got the battery opened up without permanently damaging it, by looks of it just using
Heat, IPA & and suction pad
can you help to take an image of the RGB camera sensor (pixel size, resolution, etc)? or if needed, we have high magnification optical microscope (~$120k) that can characterize the CMOS sensor. If you ship one of the RGB camera to us, I can give you the images after inspecting.
I love how people are claiming you can watch movies in 4K on this but totally ignore the fact that you're never going to use the whole width of the displays. To watch a movie at a comfortable screen size you're more likely to end up watching at around 2K, so regular HD.
The subtitles 😂
Why does the vision pro without parts pairing get the same score as some phones with parts pairing?
I guess because calibration requires someone else to deal with it? I don't think this applies with paired parts like screens or charging cables (maybe battery due a safety concern) but not to the point of it become unusable
Different class of device
@@ratvibe the class of device shouldn’t matter. What matters is the ease of repairability
That doesn't matter. Idk why this guy is pretending it does. @@ratvibe
I don't understand. if the glass has a cable all the time connecting to the battery unit, the processor board should be there also.... also , an oled display just to barely show part of the face is a design flaw..
Easiest battery replacement in any Apple device
I can't understand a 4/10 score for a device that doesn't have screws holding the battery pack together and has a proprietary power cord connector!
You can replace the battery anyway
Ive never heard anyone swap a battery on a battery pack
@@woooshbait9696really?
thanks. so the micro oled displays isn't even close to anything that is already selling on the market. I just want the displays to a product similar to an Xreal or Rokid
Apple have also master the marketing strategy
The Display Driver IC of Sony Micro OLED is developed from Sony or Apple by self?
the uOLED is same as Sony Semiconductor Solutions ECX344A ?
me on my 728p lcd: looks 4k enough
This thing is a technical marvel!❤
is it?
I don’t think it looks grainy at all. It looks better than my 85 OLED
Suddenly my Surface Laptop Go 16/256gb laptop CPU is down. It can be fixed
3380 ppi OMG
I had to stop the video to be sure that I heard/saw it correct. Crazy.
@@uykudurumufake 😂
@@AlexMkd1984 MicroOLEDbaby
not 4k but more then just 4k
Apple working with Sony is cool but doubt they would do that again in the future. Really cool headset but I can't afford it myself.
What's the difference between this Tiny Screen and the one that's in Xreal Air 2 Pro AR glasses?
4 times the density and fully solid panels
AVP: Chip is 1.4", 11.5 MP
XReal: Chip is 0.55 or 0.7", 2.1 MP
Air 2 Pro has a 50 degree FOV but something like 48 PPD. It's packing more pixels per inch but it's a very different device.
"The pack is also outputting more voltage than a normal usb c pack to keep up with the Vision Pro's precossings demands..."
Sry to say but that is a misunderstanding of why Apple used higher output voltage battery pack than lets say the typical 5v usb power. The reason they have gone with higher output voltage is because of how electricity works. If wan't to keep the power loss due to transfering (dc) power you step up the voltage.(and therefore keeping the current low) That's also the reason why Notebooks run on +20v.
Also if you are gonna use tethered headset then why not make the pack bigger with all of the processing power in it to make the headset even lighter. And then use even more powerful graphics...
It's Apple.
They don't want any part of the device to seem bulky; this external device you're suggesting would be big, heavy, and hot. It would need a fan and openings for heat dissipation, so it couldn't even go in a pocket, and would be remain permanently visible.
It's really impressive but I don't understand why they didn't use the USB C PD standard for the battery pack. Perhaps they wanted no chance that the cable accidentally got unplugged during use?
USBC is not made for battery interconnect and battery dont need 11mbit usb data as well as more complex usb controllers while something simpler can be used. USB didnt been made for power really its a extra feature allowing powering devices from host not other way around, so you dont need extra power cable. It just happend that phones needed a plug that sends data in standard way and charge in same time. Also usbc dont provide nessery cliping to secure the plug.
Actual 4K resolution as per its invention was listed as 4096x2160 which is 17:9 vs todays slightly lesser resolution of 3840x2160 which is a 16:9 aspect ratio. That being said both resolutions are still 8 million or so pixels in terms of total detail. What’s real interesting is each panel in Vision Pro is 10.75 million pixels ( 3360x3200 ) which means combined you have greater resolution than 6K panel, but not quite 8k ( 6K is 18 million pixels, Vision Pro combined is 21.5 million, and 8K is 33 million ).
Have you seen the ICNU1510 vs "Apple Vision Pro (SONY)" comparison table image? In it, it listed that the resolution was 3648*3144px, 7.5um pitch and 3,387 PPI, and with your numbers being so close, I have further belief that those are the true display specs.
ah yes, a protosaber, not as refined as a true lightsaber.
The variable opinions on the lag or lag free passthrough is interesting. You have some, like iFixit here, who says you will notice some lag in pass through....but others like MKBHD says that is not the case and is even on film playing ping pong with someone through pass through which, in my opinion, would be near impossible if pass through was laggy.
iFixit is best at opening the hardware, mkbhd is best at reviewing tech, and the fact that a lot of techtubers experience is opposite as to what iFixit is claiming especially on the passthrough, I guess the problem was on them, not on the vision pro. They should've double checked the software experience first before releasing the video ig.
Context - iFixit said there is lag, MKBHD said that Apple did it much better than competition, he never said there is no lag.
@@johnricang8791the issue is that lots of TH-camrs never tried competitors for a long time.
It is like a normal person reviewing 5k€ hifi stereo. I can tell you exactly why it sounds because I already have a 1k€ hifi stereo and I work with audio but a normal person won't tell the difference. I've tried with some friends and they weren't able to distinguish a cheap from a good speaker.
@@randomnickify yep, around 12 ms according to apple, but not big lag compared to what iFixit is claiming.
Context - MBHD can play pingpong using the visionpro which implies that the passthrough has a very small latency.
12 ms is honestly pretty good. That’s about 1/84 seconds. It makes sense that you can play ping pong with that level of lag. Most TVs used to be far worse than that a few years back and we used to game just fine on it. 12 ms is how long it takes sound to travel 4.1 meters or 13.5 ft, and musicians in a room bigger than that can play in time without fancy monitoring.
3380??!!! Woah.
3380 ppi only??? i know other micro oled panels that go over 4000 ppi...
Вт\час рассчитывать можно по акб с напругой 3,6 вольта или по выходу с напругой 5 вольт. Если надо обмануть то считают по акб, если надо честно но меньше то по выходу и 5 вольтам.
2:36 the pixel size comparison here doesn't look like you can fit 2500 in the pixel on the right, at all. Did I miss something?
why apple vision pro use that much power?
When Apple vision pro release in my mind that high density display must be curved but this is flat 😅😅
The rxternal display is curved, but the little displays for your eyes aren’t. The lenses are tho
What makes a score provisional?
Assembling/disassembling is only part of repairability, you need to consider if the necessary parts for fixing it are available to customers, their price, or wether replacing a broken part by a working one will actually work or the OS will brick the device as has happened in the past by replacing parts in iphones/macbooks.
I'll guess that if ifixit can't get access to repair parts because apple has a stranglehold on the spare parts chain, the score will go down.
Zack Nelson's Jerryrigeverything did a teardown job on this device.
It was not repairable afterwards.
