I own an 8BitDo SN30 Pro+ controller that has a neat feature: It comes with a rechargeable battery back that is user replaceable via a simple back cover, but regular AA batteries can also be used in the same slot instead.

Kinda like an Xbox controller, except that the rechargeable battery was actually included instead of being a separate purchase, and no adapter is needed for either battery types.

Honestly, I’m glad they aren’t in a rush to constantly release slightly improved models, unlike phone manufacturers for example. Wait a few years and make the upgrade count.
