Suica cards (and transit express payments in other regions) work after iPhone batteries die for a few hours.
Are you saying that an iphone can be used as a Suica card even with a dead battery? Or just that a discrete card still works when your phone is dead?
iPhones still let you use certain contactless features (like Suica) even when the battery has "run out" (ie., the main OS has shut off). The reserve battery power is enough to run Suica, CarKey support, and FindMy.
I imagine there are only maybe three people as stupid as me to try this, but just in case: it works fine when the battery runs out; but it does _not_ work during the OS update process.
