I have an iPhone 6s, fully updated. Starting from 20 December, whatsapp complains that there is not enough space on the iphone to do a backup to icloud. Before this date, everything worked fine and I don't remember doing anything particular around that time.

The backup dimension is 2.37 Gb with 878 Mb of videos. Currently I have 8.2 Gb of free space on my phone (and 40 Gb on iCloud), but whatsapp complains that I should "free 512 MB of space on the phone to do chat backup".

So, I have two questions:

1 - Why does the backup require any additional space at all? The 2.37Gb are already stored locally inside the whatsapp app; why would I need any additional space for the icloud backup?

2 - Why does it require so much more space? Is there something wrong?


It's a bug. I have the same issue:

Total Whatsapp data on my iPhone = 7GB

Free space on iPhone = 38GB

Whatsapp complains that i have to free another 1,88GB to be able to make a backup of the chats to iCloud...

  • fyi: if you turn on "Settings -> [your name] -> iCloud -> iCloud Backup -> On" then a complete backup of your iPhone INCLUDING WHATSAP CHATS will be made. So, that way you also have your Whatsapp chats backuped, so then you can turn off the backup inside the Whatsapp App. Alternatively a backup of your iPhone with iTunes also includes Whatsapp chats. – Motsel Sep 8 '18 at 19:10
