Doesn’t mean they use the same chemistry. There’s a lot of different lithium batteries.

Samsung isn’t even using the latest\greatest tech in cell phone batteries. The Redmagic 10 pro uses a silicon-carbon anode based battery in a dual cell form. It means fast charging is split between 2 batteries so there’s less battery damage on a recharge, and the chemistry is more energy dense.

Also, it seems the cell phone companies self assess the tests and report them to the EU, so take the whole thing with a grain of salt.
