How to Back Up Your iPhone
Your iPhone holds the things you'd be heartbroken to lose — years of photos, your messages, contacts and app data. And a cracked screen, a theft, a botched update or simply dropping it down the loo can strike without warning. A backup is what turns that gut-punch moment into a shrug. Here's how to back up an iPhone properly, with a copy in two places so a single mishap can never wipe everything out.
Why one copy is never enough
The phone in your pocket is the device most likely to be damaged, lost or stolen — yet for most people it's the only place their photos and messages live. Professionals follow the 3-2-1 rule: more than one copy, in more than one place. For an iPhone that's wonderfully easy: iCloud handles the automatic, off-site copy, and a computer backup gives you a second, local one.
1. Turn on iCloud Backup
Go to Settings → [your name] → iCloud → iCloud Backup and switch it on. From then on your iPhone backs itself up automatically whenever it's locked, charging and on Wi-Fi — usually overnight. This covers your photos, messages, app data, device settings and more, and it's the copy that saves you when a phone is lost or stops working entirely.
2. Back up now
Don't wait for the overnight backup before a repair, a trip or an update — connect to Wi-Fi and power, then tap "Back Up Now" and wait for it to finish. Note that the free 5GB of iCloud storage rarely covers a phone full of photos, so you may need a small paid iCloud+ plan. At a pound or two a month, it's some of the cheapest insurance you'll ever buy.
3. Add a computer backup
For a second, local copy — and the fastest way to restore a lot of data — connect the iPhone to a computer and back up via Finder (on a Mac) or iTunes / the Apple Devices app (on Windows). Tick "Encrypt local backup" so it also saves your passwords and health data. A computer backup doesn't depend on your iCloud storage and is brilliant for moving everything to a new iPhone.
4. Check the last backup
A backup you've never verified is just a hope. In Settings → [your name] → iCloud → iCloud Backup, confirm the date and time of the last successful backup. If it's days or weeks old, something has stalled — usually full iCloud storage or the phone not being left on Wi-Fi and charge overnight. Two minutes of checking now saves real heartache later.
What gets backed up — and what doesn't
iCloud Backup captures most of your phone, but a few things work differently. Anything already stored in iCloud (like iCloud Photos or notes) syncs separately rather than sitting inside the backup. Some apps — banking and authenticator apps especially — deliberately don't back up for security, so you'll set those up again on a new phone. It's worth knowing this before you wipe an old device.
Common backup mistakes
- Running out of iCloud space. The 5GB free tier fills fast and backups silently stop — watch for the warning and upgrade if needed.
- Never plugging in overnight. Automatic iCloud backups only run on power and Wi-Fi, so a phone that's never charged overnight may not be backing up.
- Assuming a new phone is covered. Check backup is on after any reset or upgrade.
iCloud or computer backup — which should I use?
The honest answer is both, because they cover different risks. iCloud is the effortless, automatic, off-site copy — it keeps working in the background and saves you when a phone is lost, stolen or destroyed, because the backup isn't sitting in the same place as the device. A computer backup, on the other hand, is a local copy you control completely: it doesn't depend on your iCloud storage allowance, it's the fastest way to restore a large amount of data onto a new iPhone, and (with encryption ticked) it captures extras like saved passwords and health data. If you only do one, make it iCloud for its automation; but adding the occasional computer backup gives you that valuable second copy in a second place — exactly what the 3-2-1 rule is about.
Phone won't back up or won't turn on?
All of this assumes the phone still works. If yours is cracked, water-damaged or won't power on, act quickly: our smartphone repair team can often get it working long enough to recover your photos and data before it's lost for good. But the real lesson is simple — back up today, while everything's fine, and you'll never need to test your luck.
