However, there is an exemption for high-performing and durable batteries until 2027. This means devices with high quality batteries that retain over 80% of their capacity after 1000 charge cycles do not need to comply with the removable battery requirement until 2027.
So premium phones like the iPhone would be exempt.
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.
