Solid state batteries seem to work, but the price of prototypes is very high. Samsung says they will soon be shipping earbuds and watches with solid state batteries, but the cost is too high even for phones. Xaomi showed an $800 phone battery. Mercedes has one prototype car with solid state batteries. Honda has one motorcycle. EHang has one flying car. Nobody seems to be past one-off demos.
I am happy to pay extra $100 for Solid State Battery on Apple Watch. I am not sure if other brands could get this advantage.
And yet Apple just isn't interested any more.
