The issue with repairability is always the conflict between water resistance, thickness and feel vs the compromises to that needed to make removable batteries or back cases work. There are ways around it but the vast majority of the market prefers solid near glued together phones so that's what companies make.

I think we've just reached the local maximum of the phone design and adding folding gives two different branches to go down: 1) same size screen unfolded but smaller folded size or 2) folded with an external screen roughly the same size as a normal phone today but it expands to a much larger one unfolded. We'd kind of reached the peak size that people can reasonably pocket so option 2 allows for even bigger screens for people willing to pay without having to have a second device (something like a tablet).

The folds do add functionality and I think there's an impulse that leads people to say they don't see the point of something just because they're not interested in it personally.

the vast majority of companies only make solid near-glued together phones, so that is all anyone buys.

if apple made a phone with replaceable batteries with a bit more thickness and some compromises on water resistance vs. cost, you'd actually see the consumer preferences play out.

you're going to have to go through some real mental contortions to support foldable phones as consumer choice while treating repairability/replaceability as inherently not worth it because you like slim designs.

We already went through the period of offering both and people preferred the thin hard to repair slabs we have now. There were quite a few phones made during the transition to the current state and the overwhelming purchasing choice was eliminate replicable batteries.

I'd love it if we could make slightly thicker phones (I put cases on my phone still I'm not chasing absolute thinness contrary to your assumptions) with the same battery capacity and feel, but there's a lot more of a trade off than just a little thickness when you go back to the old replicable battery. You lose a lot of capacity vs volume when you make the battery removable because it needs it's own plastic shell and you have to have a water resistant cavity to insert it into. Both of those eat up probably 10-20% of the capacity you can place in the same area with a bare(ish) lithium polymer pack that goes into the current design.

It's nice to believe people would agree with you if only they had the choice companies have stripped away from them to make again but it's not like people didn't have a chance to buy repairable smartphones over the current version already.. Most people just don't really think about replacing their phone's battery ever until it's a problem.

Seems like they are going to have to make that compromise, at least in the EU market. User-replaceable batteries from 2027 onwards, unless they are willing to quit the market (probably still requiring screwdrivers, but hey, its something)

Unlikely because the law includes this out for manufacturers, manufacturers are exempt from the user-replacement rule if their devices are waterproof (IP67 or higher) and utilize ultra-durable batteries that retain 83% capacity after 500 cycles and 80% capacity after 1,000 charge cycles. That's skipped over in a lot of the headlines about the law.

A lot of phones these days are at least IP67 if not better. My Pixel 8 is IP68 so it comes down to the battery capacity retention and how well they can game that measurement (slower charging etc for the measurement) but most phones are pretty good at that afaik.

I clearly haven't had good luck on this front. My iPhone is showing a battery health of "service", and a maximum capacity of 77%, after just 357 cycles.

You could try draining it to zero and recharging it without using it. Sometimes the battery life calibration gets a little off and reports bad numbers. There's not a perfect way to monitor battery health a lot of it is based on the voltage curve of the battery and that's somewhat variable from battery to battery in a way that can mess with the battery health estimate.

There's also the chance you get a slightly bad battery and just got screwed on the lottery.
