Ledger Nano X can be used on Android and iOS with the Ledger Live app without any problems.
No, that's not possible. This is not its function. You only have access to the Ledger Nano X device by using the Ledger Live software. The device and its software are only used to manage (send and receive) its own cryptocurrencies that are on the blockchain (so the cryptocurrencies are not in the Ledger Nano X device).
Nano X clearly has a battery. If the device is charged, it will last as described. If it cannot be charged then it would be a case for support.
