Why is my phone not backing up automatically?

[StuMcBill]

I've got iCloud backup set to on, on my iPhone 7, and every night it is locked and connected to WiFi, however it never seems to backup automatically?

Have I done anything wrong? Anything I should do/check?

Thanks

I stopped backing up to the cloud a while back. It became unreliable, so I switched to my iMac for backing my phone up....The only thing I'm wondering is that just maybe mobile data may need to be on to allow access for the cloud. If that isn't the issue, try toggling the Icloud switch off, reboot the phone, then turn it on again...It used to work for me.

Thanks, I'll give it a go.

Can you do a manual backup on your phone. settings, icloud, backup - backup now? Does it work or give you an error?

At night it is also plugged in and charging?
