You go to a repair shop that has one, which is what the parent poster was referring to.

Every time I have taken an apple device to a repair shop they have told me they can't get stock of the part or if I take it to an official repairer they charge more than it costs to buy a working second hand version of the device.

The option to repair exists in theory but in reality it may as well not.

It's a lie. Re-sell price of iPhones is about 70-80% of the original price, and the most expensive repair (full replacement of the unit) costs 46% of the price.

Consumer electronics steadily decline in price. Its a category error to define a curve as a point.

Example 3 years ago the Iphone 6S was released. The 64GB was priced initially at $750 US. You can now find them for 235.

This is aprox 1/3 the original price.

Since labor is a relatively stable price, replacement parts don't tend to get much cheaper, and the cost of a used model is constantly going down its not shocking that devices that aren't cheap to repair rapidly become trash.

You already see this on everything from cars to fridges.

You would do well not to assume bad faith and call people liars without good cause.

Price of the new (not refurbished) iPhone 6s on Amazon.com is $299, so the most expensive repair (replacement) will be $137.

$235 is 78% of the price. As you can see, nothing of my words is a lie, so yes, try to do well and don't call me a liar.

This was a macbook that was about 4 years old and failed because of a known faulty ssd.

I still don't believe you, because I have an experience of repairing MBP too. In my case it was damaged keyboard. They decided to replace entirely that half of the notebook. It was surprising approach and price was high, but still lower than price of the new MBP with the same CPU/RAM/SSD characteristics.

In fairness to the previous poster, replacing a keyboard should be cheaper than replacing an SSD (which is soldered into macs, requires a more expensive replacement part then needs an OS reinstall which a keyboard wouldn’t).

Apple intentionally builds their keyboards in such a way that it is incredible difficult to replace, the amount of skilled labor required doesn't make it profitable to just replace the keyboard. Its eye opening seeing a keyboard replacement being performed: https://youtu.be/4KuVvb9DTaU?t=309

Who is to blame for letting it get so far? I think its not just Apples fault, its governments fault not regulating them and consumers fault for still buying and even defending their practices (which you can very well observe in this thread).

They are replacing whole half of the notebook. It's everything except the monitor. So price is the same.

It’s not that difficult to swap an iPhone battery. You need a spudger or a guitar pick to break the adhesive around the edge, and then it’s open. A few screws to undo the battery cable, then use the pull tabs to stretch/pull most of the adhesisve our from under the battery. It’s about a half hour job and the battery + toolkit is less than $10 on eBay.

I don't have the tools to repair the fuel injectors on my car, should they become clogged with carbon. I take my car to a repair shop, where the cost of the tools (and the skills) are amortized across a number of customers.

You don't need to seriously.. the only thing you need is the right screw drivers (apple keeps changing them), battery glue strip to replace the glue after ripping it open and leak proof sealing rubber strip (you get from Aliexpress for 1$) for newer water proof models. Just watch YouTube videos
