9 days agoI’ve got a Z Flip 4 I’ve been daily driving for almost a year and a half now. The folding is quite convenient, especially with quick launch apps for like payments, but the main problem is the screen cover is peeling along the crease. It can be replaced but there’s no service centres in my city so I’d have to mail it
I don’t know about air travel. For comparison, Li batteries are about 200-300 Wh/kg, with solid state reading 3-4x that.
Jetfuel is 11000 Wh/kg. Hydrogen is 39000 Wh/kg.
By volume they might have an advantage but planes tend to care more about weight
