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 don’t use TikTok and welcome replaceable batteries, but I also still hope for a waterproof iPhone I can take swimming. Probably be harder to do.
There are a few Samsung phones that are water tight and have removable batteries. They just stopped making them since glued in batteries are more profitable.
