I expect smartphones to look more like the Pro Controller tradeoffs than the joy cons. The issue with replaceable batteries is you need the extra space for the battery structure so unless phones grow they'll have lower capacities. There's also IP ratings, phones have pretty good IP ratings these days often surviving drops in puddles etc where none of these products have any official IP rating to preserve when adding doors etc for replacement batteries.

I'm baffled that we still are thinking that we want thin phones. We have a gigantic camera bump that would be removed if the phone was thicker. Who wants a razor in their pocket, like really?

[ProfessorLayton]

Not only that, but if phone batteries were user replaceable, they could be sold in multiple capacities. So people that want "thin" phones can keep their camera protrusions, and the people that want more battery capacity could get a pack that allows the phone to sit flush on a table.

Literally win win win.

You say that like it'd be a simple process to accommodate the different thicknesses of battery..

[ProfessorLayton]

I'm not sure what you're trying to say? The replaceable battery is either thicker, or it isn't. There's not much to accommodate.

This is already a thing for some [dedicated] cameras like the Canon EOS series.

[rtkwe]

A thicker battery would need a new back built with a hump or standoffs across the whole back to increase the overall thickness to match the new larger battery thickness...

[ProfessorLayton]

Correct. This used to be done before on flip phones, and is still currently being done for dedicated cameras.

This is a solved problem and not an issue.

I've had a HTC HD2 that had exactly that[1] - an extended battery with a bump. It looked silly, but did its job and in daily usage wasn't that big of a deal, actually provided a resting spot for my index finger.
