Ok but why is it too difficult for American manufacturers and not for Chinese ones?

That doesn’t answer the question though, does it? I’ve been using a silicon carbon battery phone for over a year now and it’s the best battery experience I have ever had with any phone, by far. And it’s a foldable!

Charging is also the fastest I’ve ever experienced in a phone. 5000mAh and 60W PD charging.

I will never buy a lithium battery phone again, ever. So if Samsung wants me back as a customer, they will have to switch. And I don’t understand why American and Korean phone manufacturers are taking so long with this.
