WhatsApp is working on a new feature which will let users sync chat history between multiple devices. The feature, which is called the companion mode. It will let users link a secondary mobile device to their WhatsApp account without requiring active Internet.
Thia feature is very much similar to the multi-device support feature but not exactly the same. The multi-device feature does not let users link two smartphones to one account, it only lets users link four different devices to one single account.
Adding on to the user-friendly experience, soon, people will be able to log in to their WhatsApp account on WhatsApp Web. this is possible without connecting with your phone simultaneously.

Elaborating on this new feature, Wabetainfo says, “When users log into WhatsApp from a secondary mobile device, their chats are securely get copy to the companion device. This process may take a while to complete, so WhatsApp is working on adding the same message system available on WhatsApp Web/Desktop: it explains that chats are still in sync, so old messages are momentarily not available.”
