It’s an interesting article but I think its more likely that the ratings are calculated differently. The title makes it sound as if there was some real-world data proving that Samsung is better, but the only data source is the number they put on the energy label.
There is no inherent goal or point in life. You get to decide. You get to give your life meaning.
It can be hard. Sometimes, material conditions like poverty, working conditions or social pressure make it hard to find meaning. Sometimes, you can loose the meaning, like when you loose a loved one. A good society should help empower all people to give themselves meaning. Sadly this is not the direction many countries are taking nowadays.
But despite everything: You are ultimately empowered to create meaning for yourself. Nobody can truly take that away from you.
I don’t know, but even if they were I can’t imagine it’d be easy to prove that the labels are wrong. After all, I’m not aware of any data collection on degradation or failures of batteries at the required scale and precision. And I don’t think the ratings constitute a warranty, i.e. I don’t think you’re entitled to anything if your particular phone falls short of the after the 2-year warranty expires.
But I sure would like there to be some standard that allows collecting these kinds of metrics in a way that’s privacy-preserving and can’t be fudged by manufactureres.
