Whatsapp Messages Restore iPhone 6s/5 iClooud iTunes?

Added (1). I had an iPhone 5 and I backed up my messages via iCloud using the Settings > Chats > Back Up on the Whatsapp Application.

Then I bought an iPhone 6s and OI want to move all my messages (1.62 GB) to the new phone.

I downloaded Whatsapp on the new phone and I clicked on Restore but every time it gets close to the 90%, it starts again from 1% and this has been going on for the past 48 hours.

Re-install it again, it might work and do install Leo Privacy Guard if you need a good security app it's the best app available so far in the Play Store.
