But with iCloud Backup iPhones, it is automatically backed up to iCloud. Of course you can turn this off, but it is by default. So many people just have it on, and then they are happy to find out when they lose their iPhone that a new iPhone can only recover all their stuff. Even pictures that were taken just before they lost the phone.
Now this is by default. You can check it by going to Settings and then your Apple ID and then looking at iCloud and there is a setting for iCloud Backup. You can see it there at the bottom. If you go in, there is only one switch to turn it on. You can manually back up now. Backups happen when connected to power and WiFi. So typically if you go home at night and you plug and charge your phone and you're connected to WiFi, that's when the backup is going to happen. But it will happen at different times. If you are traveling, just make sure you have a connection to both WiFi and power for a while so you can back up your iPhone.
Now, if you want to see what happens to your backups, go to Manage Savings in iCloud Settings. You will see, in addition to the line at the top that shows you Backups, tap Backup and see what you have there. So actually in this account I don't just have this iPhone but also an iPad. Both use some space. If I click on the iPhone, this one, it will give me some information. So, for example, I can see when the last backup was. I can see the size and it will give me an estimate of how much more to add to it for the next backup.
Now I also get a list of programs and I can turn programs on or off. This is good because if you try to stick with free tier on iCloud, which is 5G with space right now, you can turn off programs you don't care about backing up. For example, Audible will store all my audio books there. I don't need to back them up. Audible they have backed up and I can always grab the book again from Audible. It will also sync my bookmarks and stuff to service. I don't need it to store data from Audible. I could turn it off if it was bigger. If you have video apps, you can know the apps where you can download movies and things you want to watch, you can also turn them off because you don't need the data backed up and it will take a lot of space.
So you can go through and find out which apps are important. What apps are not? Turn off to limit the amount of space you use in iCloud Backup. So that's how you do it. It's a great thing to have. It is great especially for typical iPhone users who may not connect to the computer and back up frequently. It just keeps everything backed up, and I'm sure it will solve a lot of headaches for Apple and Apple Store employees, who can easily give someone a new iPhone and get all the data back, and you know everything is set up as before, even if the user did not quite think about backups at all when they had their old iPhone.
