How is battery life measured under this new EU regulation?

One interesting detail is that the battery endurance rating in the new labels is tested using the same software used by many tech reviewers: SmartViser. This French automation company works with labs and manufacturers to simulate real-world usage. So now, the battery performance you see on the label is based on consistent, lab-tested data, not just marketing claims.

Do note that only certain serial numbers are affected.
