Can I travel if my Android smartphone runs out of battery?

If your tickets and passes are stored in your phone's secure element (Samsung Galaxy mobile and watch) or UICC card, many phones allow you to validate even when the battery is empty.

If your tickets are stored in the add-on application My Navigo Tickets, your phone's screen needs to be switched on to validate a ticket, you therefore need some power.

Keep in mind that if you have a Navigo Monthly or Navigo Weekly pass, you must be able to display your photo in the application (My account) so that you can show it to the inspector.
