How to update an iPhone

How to update an iPhone- Apple often provides upgrades for the iPhone. There are often a few incremental updates made to the OS during the year in addition to at least one major upgrade, which is typically used to fix problems and enhance security.

How to automatically update your iPhone

Here’s how to check if your iPhone is prepared for an automated update:

  2. Click Software Update on the General page.
  3. Select Automatic Updates from the Software Update page.
  4. Make sure the Download iOS Updates, as well as Install iOS, as well as Install iOS Updates buttons are both on by sliding them to the right, rendering them green, in order to have the iPhone perform everything automatically.

When both switches are switched on, your iPhone will download update files to the device and afterward automatically install them while it is charging and locked throughout the course of the next night.


You can choose to disable Install iOS Updates while keeping Download iOS Updates enabled. The update will download to the smartphone if you do this and wait for you to manually install it.

Tips for troubleshooting your iPhone if it won’t update

Try these troubleshooting techniques if your iPhone won’t update either manually or automatically.

To ensure compatibility, check your iPhone

For the iPhone 6S and later, the iPhone SE (first and second generation), as well as the iPod Touch 7th generation, the most recent iOS software upgrade, iOS 15, is available.

You’re out of luck if you’re still using an iPhone 5S or an earlier model. A complete list of iPhone models that are compatible is available here.

Verify that you have sufficient storage space

Approximately 3.24 GB of storage space will be required for iOS 15, but you’ll need more to install it. In order to download and install the update, your phone must have a total of around 5GB of free space.

Open the Settings app, touch General, then choose iPhone Storage to discover how much free space is currently available on your phone. On the iPhone Capacity page, the top of the page will display your available storage.

Connect to WiFi and charge your battery

The smallest issues can occasionally block an iOS update. A strong, dependable WIFI connection is required, and your iPhone should have at least 50% battery life left.

Update your device at home or at work, where you are sure to have consistent WIFI, for the greatest results. Furthermore, before beginning the update, dock or charge your smartphone.

Restart your iPhone

Any number of minor issues, such as damaged files or other flaws that can conflict with an iOS upgrade, can be resolved by restarting your iPhone.
