TL;DR
- The European Council has ended its adoption procedure for rules related to phones with replaceable batteries.
- By 2027, all phones released in the EU must have a battery the user can easily replace with no tools or expertise.
- The regulation intends to introduce a circular economy for batteries.
Battery shape (and connector) will sadly still be a thing for a long time, and usually it’s for engineering reasons, so I don’t really think it will be possible to standardize it
