You sure? I only heard of laws about repairability, not swappable batteries. You can already replace the battery of any phone, the only question is if it'll take you 1 minute (Fairphone) or several hours (every other vendor I'm aware of). The legislation might make it take maybe 1 hour instead of 2, and requires (iirc) that you can obtain legit replacement parts for a few years, but that's about it

Seeing how Motorola is trying to bypass the regulation for software updates, I don't have any hopes. https://www.androidauthority.com/motorola-eu-software-update...

That regulation doesn't apply to mobile devices at this point afaik.
