My single-issue is replaceable battery, but no new candidates are being fielded. I still have an LG V20. They're now on V50 I believe but haven't had replaceable batteries since the V20.
It's not impossible to get by without one, but personally I don't have the soldering skills to replace a modern battery (parts are just a bit smaller than I trust myself with) so that's going to be a repair charge when my current phone's battery wears down in a year or so. No reason to replace the whole phone at that point, it still runs great and does everything I need it to do. Why waste the money?
