I have made several attempts to backup my phone but each time it has failed. I connected the phone to power and started the backup process but it would never complete. Last time I tried it failed when indicating there were 13 hours to go to completion. As a result I am getting reminders: "Your phone hads not been backed up for three weeks." The ios is version 13.5.1 2.6 GB of 5 GB has been used in iCloud. 1.6 GB used by iPad, 665 MB by the phone.
