It's much easier to find the replacement part for the phone - as long as it's not more than maybe 5 years old - then it is to find the replacement part for the washing machine.
That's been my experience, anyway. Perhaps I'm just not aware of where to go for appliance parts.. but I don't have much problem finding anything else I ever want to buy on the internet.
Usually the manufacturer has them, though they may optimize for selling to service professionals, and these days there tend to be third-party sellers more focussed on consumers, as well (and you can often get parts on Amazon.)
IME, getting the right part number is often the hardest thing, though usually docs available from the manufacturer (even for units no longer sold) can be downloaded that provide this, and lots of time searching by description and appliance model can find the part, too.
My experience with this has been terrible for e.g. circular saws & power drills, to name one example.
I had a part I needed for a Makita circular saw & Black & decker power drill. In both cases buying every replacement part would easily cost 10-20x of the retail price of a new saw or power drill, compared to maybe 1.5-2x in the case of a modern phone. The aftermarket for OEM car parts is similarly brutal for most manufacturers, but for some happy reason phones are the exception.
Can I ask what phone(s) you are talking about? I replaced the battery of an iPhone 7 recently, and maybe it was just early in the evolution of these designs, but putting the screen back on with the sealant ring was the easiest part. Personally found it much harder to break the adhesive - definitely the longest step, but this was my first modern phone battery replacement.
Sure, that's possible, and I'll give you that if you're manually soldering something on a circuit board that'll be a breeze compared to the surgery of trying the same thing on a modern phone.
My point was that for the average consumer without deep electronics repair knowledge the situation has become much better. If your $500 TV broke you weren't going to find a $10 replacement for its main board that you could pop in with just the skill of operating a screwdriver. But with modern phones you can do that with just a heat gun, credit card and a screwdriver.
Thus I think even though e.g. replacing the internal memory or CPU on these devices has become practically impossible, they're a lot more repairable in practice than most other electronics, current or historical.
Meanwhile I've repaired my old washing machine quite easily.
Do you also think that Fairphone is “a lot more bulky” and “missing the mark”?
I think that Apple simply designs their devices with planned obsolescence for more profit.
My mother inherited my late-2014 iPhone 6. It still gets security updates, although it won't run the current iOS.
The battery started to swell, so she took it in for a new one. They replaced it with a refurb, since they aren't authorized to do replacements of swollen batteries on-site. It cost her as much as a replacement battery would. Presumably, the original has been refurbished and someone else is using it.
If Apple is planning for obsolescence, they're doing a poor job of it, compared to literally any other phone manufacturer in existence.
I don’t think that’s true at all. The Fairphone 2 came out the year after your mothers’s iPhone and got an OS update this year, and if she had it then she would be authorized and likely capable of replacing the battery herself.
This is one of the main things to beware of when you need to open up a phone with a heat gun and repair it. I've broken a couple of screens shortly after a repair until I realized I needed to be more meticulous about how I glued the cover back on, and to keep it in a vice until the glue dried.
I don't see how you could have a hot-swappable battery without making the whole thing a lot more bulky. Personally I think this whole "make it repairable" movement is mostly missing the mark when it comes to modern phones.
Maybe Apple is different, but if you break something on a modern $300-500 Android phone such as the screen, motherboard, sub-board etc. you can easily order a replacement from China for $10-50.
You need to own a couple of things like a heat gun, and maybe a soldering iron, but you'd also need a torx screwdriver set etc. for a "repairable" phone. The cost difference isn't that great.
Phones are wildly more repairable than most other electronics you can buy nowadays or would have bought in the 70s-90s. I know if I e.g. break the USB C port on my phone I just need a new $5-10 sub-board. Compare that to breaking something essential on my washing machine, drier, TV etc., those things are typically easy to open, but a lot harder to actually repair in practice.
