It had been in the works for a while, but now it has formally been adopted. From the article:
The regulation provides that by 2027 portable batteries incorporated into appliances should be removable and replaceable by the end-user, leaving sufficient time for operators to adapt the design of their products to this requirement.
i sure dont miss picking up three pieces and then reassembling my phone when I dropped it. my s2 had that issue for a long time until I ditched it. maybe bad design? havent had a removable battery phone since though.
