iCloud — What It Does and What It Doesn't
A friend's phone went into the pond last week. Not mine — I'd have felt worse about it if it'd been mine, and that's exactly the thought that got me. She fished it out, dried it off, and it was gone. No screen, no boot, nothing. And her first question wasn't about the phone. It was "what do I lose."
Turned out the answer was mostly nothing. Photos, contacts, notes — all sitting quietly on iCloud, waiting for a new phone to sign into. But it got me checking my own setup, and I'll admit I hadn't looked in a while.
I run three machines now — the Mac Studio, the MacBook Pro, the iPad — with Universal Control stitching them together so I barely notice which one I'm touching. That convenience makes you sloppy about backups in a specific way. When everything feels connected, you assume everything's covered. It isn't, automatically. iCloud backs up what you tell it to back up, and the defaults aren't the same as complete.
Photos and videos, yes, if iCloud Photos is on. Contacts, calendars, notes, yes. Messages, yes, if you've turned on Messages in iCloud rather than relying on the old device-only backup. Health data, yes, but only if you've got the passcode and Face ID set up right, because Apple treats that data carefully enough that a lost password can lock you out of your own history.
What doesn't come along automatically: anything living entirely inside an app that keeps its own cloud, or no cloud at all. A few of my research notes lived in an app I'd stopped using two years ago, still installed, never synced anywhere. I'd have lost those and not even remembered they existed until I went looking.
That's the part worth sitting with. It's not that iCloud fails. It's that "backed up" isn't one setting — it's a dozen small yeses scattered across Settings, and most of us said yes to some of them years ago and forgot the rest existed. My father used to say a fence is only as good as the post you didn't check. Same idea. The weak point isn't the one you're worried about.
I went through mine this week — Settings, your name at the top, iCloud, and down the list of what's toggled on. Took about four minutes. Found two things I'd assumed were syncing that weren't, and one app I didn't remember granting access to at all.
I'm not going to tell you what to turn on. Some of that's a real trade-off — storage costs money past the free tier, and not everyone wants every photo living on someone else's server. That's a decision worth making on purpose, not by default.
But my friend's phone came back to life with a new SIM and a sign-in, good as before, and that's not nothing. Worth knowing whether yours would do the same.
What would you lose if your phone disappeared today?
