How to Delete WhatsApp Backup Messages
One of the most popular smartphone messaging apps available, WhatsApp automatically backs up every message sent or received for seven days, enabling you to restore any accidentally deleted conversations. While it is a nice safety net, the automatic message archiving devours lots of memory. WhatsApp provides simple methods for deleting chat messages but provides no way to delete the automatic backups. Deleting the backup messages to free those valuable internal resources requires downloading a free Android app called WCleaner.
