Handful of Apple Vision Pro units develop identical crack in cover glass
- sandworm101 3y ago>> The reports all mention that the crack became visible suddenly and for no apparent reason, after the headsets had been connected to the external battery pack and stored overnight (some in Apple's Travel Case) with the soft front cover attached. It is glass. The device was being charged, which means some heat gradient between the charging battery and the outside world. That thin 3d-shaped glass cracks under thermal stress should be no great surprise.
- nickthegreek 3y agoMaybe no surprise to Apple, but it is certainly a surprise to the purchases who shelled out $3,500.
- reaperman 3y ago> Maybe no surprise to Apple It would be a huge surprise for Apple if a lithium battery inside the visor caused the cracks, as they did not design the head unit to include any internal battery.
- amelius 3y agoMaybe they placed the visor near or on top of the battery while it was charging?
- asadotzler 3y agoThere isn't a significant battery inside the visor. Unplug the external battery pack you keep in your pocket and see what happens.
- reaperman 3y agoI would need someone else to tell me because I'm not buying a $3,000 toy.
- iAMkenough 3y agoThere's no battery behind that glass, so it's the processors or another component generating heat while stored.
- reaperman 3y agoIIUC there's no lithium battery inside the Apple Vision Pro at all. The power for it is supplied by an external batter connected via USB cable.
- sandworm101 3y ago>> The reports all mention that the crack became visible suddenly and for no apparent reason, after the headsets had been connected to the external battery pack and stored overnight (some in Apple's Travel Case) with the soft front cover attached. The battery is external, but mobile. The users may well have stored it inside the thing. Plus, it is understood that this device continues to draw power while not in use, which also suggests a possible thermal gradiant.
- nottorp 3y ago> Given that the battery is external to the headset, any heat generated would presumably need to be caused by a background software process gone haywire. Apple is very good at background software processes taking 100%-500% cpu (100% == one core in Apple land).

- reaperman 3y ago> That thin glass cracks under thermal stress should be no great surprise. Actually, the thinner the glass is, the less likely it is to crack due to thermal gradients. It is thicker glass which experiences greater stress. The equation for thermal stress is: thermal_stress = (coefficient of thermal expansion) ∙ Young’s modulus ∙ ∆T which for glass, works out to about 0.63 MPa per 1 degC temperature difference between the centre and edge of the glass. Thinner glass has less temperature difference, so lower stress. Furthermore, surface roughness and type of imperfections lower the amount of stress needed to cause a failure, so Apple's obsessive polishing makes the glass withstand higher stress than usual.
- brookst 3y agoThanks for the info and model! But if the thin glass is bonded to the aluminum frame by glue, would that not change the calculus? If we imagine hot air on one side of the thin glass and cold aluminum on the other? I’m very skeptical of the “charging thermals cause cracks” theory, seems more likely that minor manufacturing defects might do so when the headset cools from a session. But I suppose we’ll hear more than we want to in the next few weeks.
- givinguflac 3y agoIf it had cracked while in use, perhaps due to the processors heating, but the battery is external to the device, so I don’t see how that’s relevant. I suspect a manufacturing defect personally, given that the heat comes from the computer inside and not the battery.
- layer8 3y ago> The device was being charged The external battery pack is the only battery, there is no internal one being charged. There is also no mention of the external battery being charged.

- asadotzler 3y agoare you a bot? you seem like a bot. I've been watching you and you're very bot-like. tell me otherwise.
- nickthegreek 3y agoYou are entitled to your opinion. I don't have the time nor the will to engage with your concerns.
- bookofjoe 3y agoIt would never occur to me to store the device connected to its battery inside the case — or outside the case, for that matter. I don't like the idea of that dense, heavy battery potentially getting displaced from the holding strap in the case cover and banging around inside against the Vision Pro. Since I got mine February 2 I've kept both my batteries attached to chargers when not in use.
- cptcobalt 3y agoThe Apple case has safe stowage for the battery. It is categorically not going to be banging around if you secure it in the case properly. I've taken mine to work frequently since release and have not observed it coming loose.
- bookofjoe 3y agoFair enough; good to know.
- asadotzler 3y agoWell, you probably didn't read Apple's instructions then :-)
- bookofjoe 3y agoCorrect
- postalrat 3y agoWhy is it glass with a plastic coating instead of solid plastic? Apple's use of glass has to be part of a scheme to make money replacing glass parts.
- fishpen0 3y agoYeah, it makes sense for phones, since the touchscreen feel affects perception of quality. But this is literally just a gimmicky non-touch display and didn't need to be real glass
- staticautomatic 3y agoMaybe it has desirable properties compared to plexi.
- postalrat 3y agoPolycarbonate would be a better choice than plexiglass/acrylic. What advantages does glass have? More likely to break and more repairs?
- jdc0589 3y agoscratches. its all about scratches. any poly will scratch pretty easily compared to glass, which is a bad thing when its a lens you are looking through. You could make the argument they could just design an easily replaceable poly lens at a reasonable price, but.....its 2024 device manufacturers hate the idea of any user replaceable parts.
- gpm 3y agoThe part that is cracking is plastic on the outside glass on the inside, it doesn't get the scratch resistance benefits.
- postalrat 3y agoDo you wear glasses or know someone who does? Most of us have plastic lenses with an anti-scratch coating. It works pretty well. What advantage would there be to switch from plastic lenses for practical items like glasses to glass lenses with a thin soft plastic coating?

- dehrmann 3y agoSteve Jobs would have responded with "you're wearing it wrong."
- Terretta 3y agoHe didn't say this. Wired, however, did. If you go to the source, Apple/Jobs took accountability. But Wired got clicks.
- reaperman 3y ago> He didn't say this. Wired, however, did. If you go to the source, Apple/Jobs took accountability. But Wired got clicks. I think you got most of this wrong. The "you're holding it wrong" meme started on MacRumors, not Wired. MacRumors forum user samcraig emailed Steve Jobs about the low signal issue he (and many others) experienced while holding the new iPhone 4 in a specific way. He asked "Question - What's going to be done about the signal dropping issue. Is it software or hardware?" Steve Jobs himself emailed back to samcraig: > Non issue. Just avoid holding it in that way. He also later responded back with the following statement. This was the first "official statement" from Apple at the time, sent to tech news outlets. > “Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases.” So literally neither Jobs, nor Apple, took any accountability. Screenshots of that email exchange with Steve Jobs are still available online[0]. Furthermore we don't have to doubt the veracity of the screenshots because just one week later, Apple PR disputed[1] a different fake email chain with Steve Jobs, but Apple PR never disputed this email chain, publicized only one week earlier. If it was fake, they would have told outlets it was fake at the time. 0: https://www.macstories.net/iphone/steve-jobs-on-iphone-4-reception-issues-just-avoid-holding-it-in-that-way/ https://www.macstories.net/iphone/steve-jobs-on-iphone-4-rec... 1: https://techcrunch.com/2010/07/01/steve-jobs-emails-fake/?guccounter=1 https://techcrunch.com/2010/07/01/steve-jobs-emails-fake/?gu...

- paul7986 3y agoCurious those who bought it a few weeks to a month ago... are you still using daily and how?
- ChicagoBoy11 3y agoI am. It has essentially become my favorite computer for general "puttering" -- watching content, light browsing, messaging. Whereas before maybe I'd curl up with my mac in my lap in bed, or doom scroll on my phone, I now use it, and it is far more enjoyable and comfortable. For FOCUSED work at my job, where I really want no distractions and to just stare at something for a while and work deeply on it, it has been nice to use it as a replacement monitor. But, for general work, I still prefer my "normal" two-screen monitor setup at work, since it is easier to task-switch and go talk to people and come back, and AVP doesn't yet support multiple monitors.
- paul7986 3y agocool and have you previously used VR headsets prior and frequently too? Im interest in developing bunch of ideas for it and as soon as it shrinks down to glasses size and or close ...it or one of it's competitors becomes the next iPhone. Meta Ray Ban's seem to be selling well and all they do is reliably and solidly take pics and live video. A dataset to show people want smart glasses as well how many people in the world wear some type of form of glasses and also like taking pictures? I love my Meta Ray Ban's i bought in October.
- ChicagoBoy11 3y agoHave had several VR headsets, ranging from a Vuzix way back in the day to the Valve Index and Q3. This is the first one where I have actively OPTED to use for something other than gaming. The one thing I’ll knock is that other devices I’ve owned have been more comfortable (notably the Valve Index, which out of the box has had the best comfort of any device I’ve had, although I cannot use it lying down/on the couch because the head strap is so bulky).

- theyinwhy 3y agoNow we know why Apple does not sell to EU yet, where there is a 6 month warranty by law for most goods.
- gambiting 3y agoIt's not a warranty, It's that the seller is responsible for any manufacturing defects, and in the first 12 months(6 months in the UK) any defect is presumed to be a manufacturing defect automatically unless the seller can prove otherwise. After that time the seller is actually responsible for 6 years after the original sale, but the responsibility is on the buyer to demonstrate that a fault is a manufacturing defect.
- lm411 3y agoWhy would that matter in this case? Apple has a 12 month warranty on this and most of their other hardware. Also, I expect most people shelling out $3500 for a headset are going to get AppleCare+ which also covers accidental damage.
- asadotzler 3y agoAppleCare users are paying hundreds of dollars for this fix.
- iJohnDoe 3y agoSide rant about Apple. I never understood why Apple took such a hardline on offering repairs and charging so much for them. They are one of the most valuable companies on the planet and they have always squabbled over repairs. They went through such great lengths with their sensors about detecting water damage to iPhones that prevented people from getting legitimate repairs done that had nothing to do with water damage. Come on Apple, do good faith repairs. You can afford it. People already love Apple products. Repair your stuff without treating everyone like a criminal.
- phmqk76 3y agoWhat a disaster of a product. This isn’t a true Gen 1 product in the sense that the iPhone was. Apple waited an entire decade after the Rift was released, and released a headset that didn’t leapfrog the industry in any meaningful way. Steve Jobs would have shitcanned this months before the announcement and told his team to go back to the drawing board. Do I think that 5 years from now Apple will have a worthwhile product at a reasonable price point? Maybe. Maybe not. But to expend all that social capital on a device that sucks is really destructive to the brand, as is the insistence that it gets to collect tens of billions a year in rents because it owns the most popular computing platform for most people.
- wkat4242 3y agoWeird. JerryRigEverything showed that the cover glass is actually plastic. It's got way too low scratch resistance to be glass. And plastic shouldn't crack like this. Maybe only the top layer is plastic?
- asadotzler 3y agonot accurate. the cover glass is wrapped in plastic. it's a glass sandwich with plastic as the bread. it is glass.
- wkat4242 3y agoAh I see. But I wonder why they went for this. Why put the most scratch-sensitive material right on the outside? This way you get all the negative sides of glass (high weight, cracking under pressue or impact) while you get none of the benefits (scratch-resistance). And in this case the side of the material that's exposed to the user is plastic. Why would Apple brag about it being glass if the user can't even notice it? :)
