I want removeable batteries in my phone, largely because it means I don't have to buy them a lot!

I ran my LG G5 with replaceable batteries from 2016 through 2021, at which point there were no affordable replaceable-battery phones left. I bought quite a few replacement batteries, even trying aftermarket batteries with varying levels of success after the OEM LG ones were discontinued.

That is, of course, a problem for manufacturers that want to sell a lot of phones.
