Not really… the rules were heavily influenced by big tech in a way that basically exempts many devices. For example iPhone 15 onwards already meets the defined standard and thus doesn’t need a user replaceable battery.
So the headline is misleading. Removable batteries aren’t mandatory. They’re only mandatory if the battery fails to meet certain performance standards.
Based on other comments, there are apparently two separate sets of rules. One of them has exceptions and supplies specifically to phones and tablets, and one of them doesn't have any exceptions and applies more generally.
