Among the many changes, the new rules would require batteries in consumer devices like smartphones to be easily removable and replaceable. That's far from the case today...
I’ve never lost a phone to water damage in my lifetime either before or after batteries became more difficult to swap.
I have bought some old used electronics lately. Having an easily accessible and replaceable battery in the Game Boy Advance SP and the Nintendo DSi is very nice though.
I’d probably replace the battery on my phone right now if I could.
