I already got it for you recently Apple Vision Pro teardown from iFixit shown. In the video, the new headset is taken apart and some technical secrets are revealed. This post is about another iFixit video about the device. There are X-rays and CT images, details on the resolution and pixel density of the displays, and a comparison Quest 3 from Meta, a look at the external battery and a preliminary assessment of whether it can be repaired. So a well-put together knowledge package for everyone who is interested in the Vision Pro.

Displays with micro-OLED technology, but theoretically without 4K
Together with Evident Scientific, iFixit examined the Vision Pro's two displays and determined the actual resolution. It was also noted that micro-OLEDs were installed. Although “installed” isn’t necessarily the right word. Because it is a technology called “OLED on Silicon”. It is therefore a chemically produced composite of components that is not soldered together.
When it comes to resolution, Apple is credited with clever marketing, as the Vision manufacturer has only ever said that every display offers more pixels than a 4K television. The device was never directly associated with 4K. Together with Evident Scientific, iFixit calculated the resolution of a Vision Pro display to 3.660 x 3.200 pixels. Of course, this doesn't come close to the standard width of a 4K television (3.840 pixels), but it exceeds its height (2.160 pixels). Mathematically, more pixels due to the shape, but not 4K in terms of definition.
Information about ppi and ppd for the Apple Vision Pro
The calculations for pixel density in pixels per inch (ppi) and pixels per degree (ppd) are also interesting. The first indicates the general pixel density on a (flat) display, resulting in a comparison value for the values of Mac, iPad and iPhone displays. The second value gives an indication of the quality as headset displays and their comparison with similar hardware.
Since the above-mentioned resolution of 3.660 x 3.200 pixels is on a quite small display, the pixel density is given as around 3.380 ppi. This is remarkable, especially in comparison: the iPhone 15 Pro (Max) has 460 ppi; the current iPad Pro has 264 ppi; the current 16-inch MacBook Pro has 254 ppi. The closer you bring a display to your eye, the smaller the pixels have to be and the higher the ppi number has to be in order to make the pixels “invisible” and a “Retina” image to be able to offer.
Despite the impressive numbers, it is stated that the Apple Vision Pro's image still appears grainier/blurrier compared to other devices. And that is due to the second value, the ppd. The value describes the visible pixels per degree of field of view. With an approximate value of 100° for the field of view, approximately 34 ppd is determined. An iPhone 15 Pro Max at 30 cm away has around 94 ppd and a 65 inch 4K TV at around 2 meters away offers around 95 ppd.
Image quality of “Extended Reality” depends on other factors
It should also be noted that the quality of the depicted environment does not only depend on the displays. The external cameras and the hardware that processes and forwards the incoming images also play a major role. That's why the passthrough option in Meta Quest 3 isn't as good as the depiction of the environment in the Apple Vision Pro. The Vision Pro is specifically designed for this with its visionOS, while the Quest 3 is a VR headset that only offers passthrough for orientation and not as a functional basis.
Details about the Vision Pro battery: three batteries in one
How already shown in this article, it says on the outside of the Vision Pro's battery pack that it offers 35,9 Wh and has a rated capacity of 3.166 mAh. However, the iFixit video shows that there is more to the difficult-to-open aluminum housing.
The three individual batteries that are combined here are each printed with values of 15,36 Wh (i.e. a total of 46,08 Wh) and 3.969 mAh. The Vision Pro battery is believed to only receive an 80 percent charge by default to extend its life (similar to the equivalent iPhone battery conservation option).
How easy is the Apple Vision Pro to repair?
The main device and the technical components installed in it are not easy to repair, at least for laypeople. When you open the device it becomes clear that the glass and films cannot be removed without damage. The battery pack is also not that easy to open. However, since many of the external components of the headset (headbands, speaker bands, light seal, spacers, etc.) are easily removable and replaceable, the Apple Vision Pro gets a gracious preliminary rating of 4/10 repairability.
