WhatsApp made things a lot easier by recently introducing easy chat transfers between Android to iOS and vice versa. This ability undoubtedly avoids the hassle of switching OSes and now, the Meta-owned messaging platform might soon improve the capability by adding a new feature it is testing right now.
A recent report by WABetaInfo suggests that WhatsApp is working to introduce the ability to transfer chats to another device without making any chat backups. WhatsApp beta for Android version 2.23.1.25 hints at a new ‘Chat transfer to Android‘ option.
Although, you should note that backing up chats is always a good idea and helps in situations where your phone gets lost or stolen.
