Is that still a constraint? Why can't we make clips that don't fail? We made USB connectors reliable with type-c, and cylindrical batteries are reliable. What if batteries attached via small screws? A little strip on the top could contain the protection electronics and screws, and the strip could be standard across all battery sizes, you could use a too-small one in a pinch and just have some empty space. Add a little flexibility to prevent damage from flapping when dropped due to only being secured at one side so you don't need a screw hole wasting space on the other end. I think the bigger concern is NFC, batteries seem to get in the way of that.

Clips failing is a product of mechanical wear with minimal physical space available meaning any design is a forced tradeoff of clip lifetime vs battery capacity. > cylindrical batteries are reliable Uhhh. Phones and laptops didn't move away from cylindrical cells for fun and excitement. A cylindrical battery uses less than 80% of the available space, and as a byproduct necessarily has <80% of the capacity. > What if batteries attached via small screws? Then you're requiring tools to replace the batteries, so you aren't getting easily replaced batteries that seems to be what's on the table. > A little strip on the top could contain the protection electronics and screws, and the strip could be standard across all battery sizes, Not sure what you're saying here - it sounds like a single standardized power logic board that every manufacturer uses regardless of battery size? Seems like that would necessitate low end devices have a massively over provisioned control board.
