How to Update iPhone 12: A Step-by-Step Guide

Updating your iPhone 12 to the latest software is a simple process that can be done in just a few steps. All you need is a Wi-Fi connection and enough battery life or a charger nearby. Once you’ve completed the update, your iPhone 12 will be running the latest version of iOS, offering you new features, security updates, and improved performance.

Step by Step Tutorial: How to Update iPhone 12

Before we dive into the steps, let’s understand what we’re aiming for. Updating your iPhone 12 ensures that you have the latest features, security patches, and bug fixes provided by Apple. It can also improve your phone’s performance and compatibility with apps.

Step 1: Connect to Wi-Fi

Make sure your iPhone 12 is connected to a stable Wi-Fi network.

Having a reliable internet connection is crucial because the update files can be quite large, and you wouldn’t want your update to be interrupted due to a poor connection.

Step 2: Ensure Enough Battery Life

Your iPhone should have at least 50% battery life, or be connected to a charger.

Updating your software can be power-intensive. If your battery level is too low, your phone might not have enough juice to complete the update, which could cause problems.

Step 3: Access Settings

Go to your iPhone’s settings by tapping on the ‘Settings’ app.

This is where all the magic happens! The ‘Settings’ app is the control center for all your iPhone’s functions and where you’ll find the option to update your software.

Step 4: Navigate to Software Update

Scroll down and tap on ‘General,’ then tap ‘Software Update.’

Within the ‘General’ settings, Apple has included a dedicated section for updating your iPhone’s software. It’s designed to be easy to find and use.

Step 5: Start the Update

Tap ‘Download and Install’ to begin the update process.

After tapping ‘Download and Install,’ your iPhone will begin to download the update. You can continue to use your phone while the update is downloading, and you’ll be notified when it’s ready to install.

After you’ve completed the steps above, your iPhone 12 will begin the update process. The screen will display the update progress, and your phone will restart once the update is installed. When it turns back on, it’ll be running the latest version of iOS.

Tips: Updating iPhone 12

  • Always back up your iPhone before starting an update, just in case something goes wrong.
  • Perform updates at night or when you don’t need to use your phone, as the process can take some time.
  • If you’re having trouble updating over Wi-Fi, try updating through iTunes on your computer.
  • Make sure you have enough storage space on your iPhone for the update. You might need to delete some content if your storage is full.
  • If the update seems to be taking an unusually long time, reset your network settings and try again.
