Nio making phone is to serve users with best phone/car integration. Iphone does not have uwb support. If Nio build its own phone, it can create the best car/phone combo for best user experience. I doubt nio phone will have any major profit contribution. It will be good if the phone business is break even.
Investorplace really has lots of bad publications with insidious intend to wrap facts. NIO is not new to battery swapping. Battery is always part of NIO service since inceptiom. Nio is already a global leader in battery swapping. Nobody is any way near Nio current scale of 1300 swapping stations.
