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.
Download and install WCleaner (see Resources).

Open the WCleaner app to automatically initiate a phone scan and detect WhatsApp files. WCleaner will sort files into four categories: images, videos, audio and backups.
Select the backup category to see the precise number of included files as well as the amount of space they occupy. Select a group of files or the individual files you would like to delete.
Tap the trash can icon to delete the selected backup files.
If you would like to delete all of the saved WhatsApp files -- including images, videos and audio along with the backed-up messages -- click the "Delete All" button on the WCleaner's main categories menu.
WCleaner enables you to preview selected files before deleting them. Simply select the desired file and tap the "Open" button to view the preview.
WhatsApp automatically saves conversations every day at 4 a.m. local time. You may also run a manual check to ensure that the app has saved the day's content. From the WhatsApp settings options, select "Chat History" followed by "Backup Chat History." Tap the "Yes" button to manually preserve the recent chat history.
WhatsApp saves backup files to the phone's internal memory as well as to the SD memory card when space is available.
WhatsApp backup files are phone number sensitive, meaning you must use the same phone number or the same SIM card to access the backup files.
