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 can’t see any added value of having an unremovable battery that isn’t entirely outweighted by the advantage of you being able to replace it.
Giving up your right to easily replace a key part of your phone just so in the event it gets stolen a thief can’t take it out, to me feels like saying that pissing on your food so the person next to you won’t eat it while you are gone is a good idea.
Additional points:
You know what instead actually prevents your phone from being stolen? Paying attention to your pockets and avoiding to flex the latest iphone model around. I am absolutely sure “safety” and “consumer security” are points companies will bring up against user-removable batteries
