That’s strange, considering they all use the same battery suppliers.

It makes sense once you consider that these numbers are the manufacturers self reporting. That means they aren’t comparable, so drawing conclusions like ”manufacturer X has better batteries than manufacturer Y” from these numbers is silly.

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.

Could be a difference in how they've set up charging cut off points.

Well, it could be that their electrical design or engineering teams have a bigger budget for prototyping and R&D. It's not just the battery that affects the charging function.

Anecdotally it seems to be the case for me. I switched from the A series to the Pixel and I'm pretty disappointed in how quickly my battery life has degraded.

It's got to be a lie
