How to Update iOS on iPhone

Tap through each step to update your iPhone.

  1. Connect to Wi-Fi and plug in a charger

    Since the update can be large, connect to Wi-Fi first, and plug in a charger if your battery is low.

  2. Go to "Settings β†’ General β†’ Software Update"

    In the Settings app, tap "General," then "Software Update."

  3. Tap "Download and Install"

    If a new update is available, you'll see its version details along with a "Download and Install" button.

  4. Enter your passcode and wait for it to finish

    During installation, the Apple logo and a progress bar appear on screen, and the phone restarts automatically once it's done.

  5. Why it's useful

    Updating to the latest iOS patches security vulnerabilities and unlocks new features, keeping your iPhone safer and running more smoothly.

Keep your iPhone secure with the latest iOS

Updating to the newest iOS version closes known security holes and often brings performance improvements and new features, so your iPhone stays both safer and more capable.

Plan the update around your schedule

Since a large update download and installation can take a while and briefly restart your phone, it's worth starting it when you don't need your phone for a few minutes β€” overnight while it's charging is a common choice.

Frequently Asked Questions

Will updating erase my photos or data?

No, a standard software update doesn't erase your photos or app data, but backing up to iCloud or a computer first is still a good precaution in case anything unexpected happens.

Can updates install automatically?

Yes, turning on "Automatic Updates" in the Software Update screen lets your iPhone download and install new updates overnight on its own.
