This is a most excellent place for technology news and articles.
I don't think you said anything differently? The article said ALL batteries must comply by 2027. You appeared to say high performing batteries don't have to follow the law until 2027. Both of these statements, the original post and your revision, are true -- all phones, including high performing batteries, must comply in the EU by 2027.
