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.
The information to be provided pursuant to Articles 3 and 4 shall be obtained by reliable, accurate and reproducible measurement and calculation methods, which take into account the recognised state-of-the-art measurement and calculation methods, as set out in Annex IV.
Article 6
Verification procedure for market surveillance purposes
Member States shall apply the verification procedure laid down in Annex IX when performing the market surveillance checks referred to in Article 8(3) of Regulation (EU) 2017/1369.
It kind of isn’t. The EU is giving the cell companies guidelines on how they should test their batteries, and then report their numbers back to the EU. So “Apple” are testing their apple phones and then telling the EU their alleged numbers.
Standardized testing isn’t the end all be all. Manufacturers have wiggle room. Most of the time you can also voluntarily derate yourself. EPA testing is standardized, but there’s a surprisingly wide margin that you can test your car at.
BMW is pretty famous for derating their HP output so they’re closer to whats available at the wheels. Every other manufacturer will measure at the crank (the balls)

the actual legislation is not that specific as far as i can tell:

Awesome! Good to know its based off some kind of standardized testing. This is good for everyone!
