It's official: Smartphones will need to have replaceable batteries by 2027

The big one at the moment - at least in the UK and IMHO - is disposable vapes. I see them everywhere, just tossed on the ground or at the side of the road. The reason I see them is because of their flashing blue LEDs still running, meaning there's at least a working battery and support circuitry in there. It's disgusting that something like that is tolerated. I'm hopeful that the requirement to have user-replacable batteries will eliminate them by making them uneconomical compared to standard vapes.
