How can I recover data on my new iPhone if my old one was destroyed?

See the general process described here:

Restore your iPhone, iPad, or iPod touch from a backup - Apple Support

Once you initially sign-in with your Apple Account, you’ll be presented with the available options specific for your account.

Do you have a Mac or a PC? We ask because you can use that device to log on to your iCloud account to see if your iPhone backups are there.

This Apple Support document should provide some help and guidance:

View and manage iCloud device backups - Apple Support

If you were synchronizing data on the old phone to iCloud, you would synchronize the new phone to iCloud to get that data. You would get most other things by restoring a backup.

In the case of music purchased somewhere other than the iTunes Store, and manually synchronized to the old phone, you would need to manually synchronize it to the new phone from your computer.

iCloud backups do happen automatically if you have that option turned on, there is enough free iCloud space, and the phone is given chances to do them. (I.e. left connected to power and Wi-Fi Internet service, with the screen locked, as would be common when charging a phone overnight.)

iCloud synchronization would also be happening automatically (and in this case, incrementally) under appropriate conditions.

FWIW, I simply assume that Automatic iCloud Backups and Sync’d iCloud data exists and point folks in that direction.

Anyone who IS consciously backing-up and Syncing knows that they’re doing it.

Anyone who doesn’t know probably IS thanks to Apple’s defaults.

The small remainder can come back and ask why no backups are listed and/or there is no iCloud data.

I don't. I'm amazed at the number of users who post who do not have a backup at all.

My guess is that most of them balk the first time that they try to set up iCloud backups because they have to buy extra storage space and they decide to do this "later" and then forget about it.

I guess the first question to ask here is.......were you backing up your old phone to iCloud or to a computer?

Please start your own thread instead of hijacking this one.

Perhaps it’s INDEED an invalid assumption on my part. 🤔

I really thought that the iOS default automatic backups would pickup the vast bulk of the users.

Perhaps not daily, but at least fairly regularly.

Perhaps they do. But on this site, we only see posts from users who are having problems, and it is amazing to me how often we learn that the user does not have a backup, or does not have anything close to a current backup.

Thanks for this.

Thanks for sharing your perspectives.
