In this guide, we’ll show you step-by-step how to safely update your iPhone without losing data. Whether you’re updating to iOS 17.4 or the next big iOS release, this guide has you covered.
Why iPhone Data Loss Happens During Updates
While most iOS updates are smooth, data loss can happen due to:

- Bugs or glitches during the update process
That’s why creating a backup is the golden rule.
Step-by-Step: How to Update Your iPhone Without Losing Data
Here’s exactly what you should do:
Step 1: Check Your Storage
Make sure your iPhone has at least 5GB of free space before updating.
To check storage:
- Go to Settings > General > iPhone Storage
If storage is low, delete unnecessary apps, media, or offload unused items.
Step 2: Backup Your iPhone
This is the most critical step. You can choose between iCloud and computer-based backups.
Option 1: Backup with iCloud (Recommended)

| 2 | Go to Settings > [Your Name] > iCloud > iCloud Backup |
| 3 | Turn on iCloud Backup |
| 4 | Tap Back Up Now |
Make sure the backup completes before proceeding.
Option 2: Backup with a Computer (Mac or Windows)
| Device | Backup Method |
|---|---|
| Mac (macOS Catalina or later) | Use Finder |
| Windows / Older Macs | Use iTunes |
Steps:

Step 4: Download and Install the iOS Update

Let the update complete. Your iPhone will restart during the process.
Step 5: Verify Data After Update
Once your iPhone restarts:

- If anything is missing, you can restore from your backup
What to Do If You Lose Data After an Update
In rare cases, you may notice missing files. Here’s how to restore your data:
| Backup Method | Recovery Step |
|---|---|
| iCloud Backup | Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings > Set up iPhone > Choose Restore from iCloud Backup |
