Hi
I have a Ledger Nano S and was curious as to how the information is retained on the device.
Let's say I have restored my device with my passphrase and unplug it from USB power and place it in my drawer. If in 50 years from now if I plug it back in, will it still have everything "remembered" so I don't need to restore the device again.
Was just thinking about this and not sure if it contained like a little battery of if a chip is somehow programmed (physically)?

And how would it affect the fees required?
