I bought a new iPhone 6s Plus yesterday. I had been backing my old iPhone 5 up to my computer. I thought the new phone was set for automatic backups to iCloud but I just got a notification that the phone had not been backed up for many months.
How do I set it up to back up to iCloud automatically at a certain time of the day?
iPhone 6s Plus, iOS 9.2.1
You cannot set it for a certain time of day. Once iCloud backup is activated on the phone, it will backup once every day when the device is connected to power, Wi-Fi, and the screen is locked. Go into Settings>iCloud and make sure Backup it turned on, and you can try a manual backup. You can use this support document to troubleshoot iCloud backups.

iCloud backups only occur when your phone is charging, locked, and connected to wi-fi. To check that this feature is on, go to Settings > iCloud > iCloud Backup. It is not possible to set it to automatically back up at a certain time.
