When iCloud Backup is turned on, the iPhone will automatically backup its data such as settings, contacts, etc. to the cloud when the iPhone is plugged in, locked, or connected to Wi-Fi. If multiple iPhone devices use the same iCloud account, the iCloud storage space would be full soon. Sometimes, you may want to turn iCloud Backup off if you don’t want your individual privacy to be synced to the cloud or if you don’t hope your iCloud storage space to run out soon. Here in this page, I will show you how to turn on or off iCloud Backup on iPhone 6s/7.
Step 1: Turn on your iPhone and tap the Settings icon.
Step 2: After the Settings app opens, scroll down to look for iCloud. When you see the iCloud option, tap it.
Step 3: Scroll down to the Backup option and tap it.
Step 4: Tap the button to the right of iCloud Backup. When an alert asks if you want to start/stop iCloud backup, just tap OK to turn it on or off.
