Before you start updating your iPhone to iOS 16, make sure that your smartphone is at least 50% charged. However, it’s recommended to plug in your device to a power source before initiating the update.

Also, make sure to connect to a stable internet connection - a Wi-Fi network with an unlimited data plan preferably. Major updates like iOS 16 tend to require a lot of data. A connection based on a limited plan may cause inconvenience.

To update your iPhone, follow these steps:

  1. Open the Settings app and tap on General > Software Update.
  2. If the iOS 16 update is available, it will appear here.
  3. Tap on Download and Install to start downloading the update.
  4. You will be asked for your passcode to verify the process.
  5. You may be asked to select whether or not to use cellular data. Tap on the option that suits you.
  6. You will be asked to agree to Apple’s terms of service. Tap on Agree to proceed.
  7. Once the update is downloaded, tap on Install Now to begin installing the update.

Upon tapping Install Now, your device will shut down for the update to begin installing. It will take a while for the update to install. Users are advised to be patient and shouldn’t try to manually switch off or switch on the smartphone during this time.


Once the update is installed, your smartphone will automatically boot up. Use your passcode to verify your identity, after which you can continue using your iPhone.

Your Apple smartphone should now be running the latest software version (16.3.1). To check, you can go to Settings > General > Software Update. While you’re at it, you can also enable Automatic Updates to omit the need for manual intervention when the next iOS update becomes available.

Apple’s iOS 16 and its follow-up updates are available for the iPhone 8, 8 Plus, and the newer iPhone X, 11, 12, 13, 14, and SE (2,3) series. While it isn't mandatory, it is certainly recommended to use the latest version of iOS for the best experience on an Apple smartphone.
