How to Update an Old iPad to iOS 15

Updating your old iPad to iOS 15 can breathe new life into your device, giving you access to new features and improved performance. Follow these steps to ensure a smooth update process.

Step 1: Check iPad Compatibility

First, ensure your iPad is compatible with iOS 15.

Before getting too deep into the update process, it’s crucial to confirm that your specific iPad model supports iOS 15. Apple has a list of compatible devices on their website. Models like the iPad Air 2 and later can run iOS 15.

Step 2: Backup Your Data

Second, back up your iPad to avoid losing any data during the update.

You can back up your iPad using iCloud or iTunes. To use iCloud, go to Settings > [your name] > iCloud > iCloud Backup, then tap “Back Up Now.” For iTunes, connect your iPad to a computer, open iTunes, and select “Back Up Now.”

Step 3: Connect to Wi-Fi and Power

Third, ensure your iPad is connected to Wi-Fi and plugged into a power source.

A stable Wi-Fi connection is essential to download the update, and being plugged into power prevents your device from shutting off during the process, which could cause issues.

Step 4: Download and Install iOS 15

Fourth, download and install iOS 15 from the Software Update section in Settings.

Go to Settings > General > Software Update, and your iPad will check for available updates. Tap “Download and Install” to begin the process. Follow the on-screen instructions and let your device handle the rest.

Step 5: Follow On-Screen Instructions

Fifth, follow the on-screen instructions to complete the installation.

Once the update is downloaded, your iPad will restart and begin installing iOS 15. Follow any additional prompts to complete the setup process.

After completing these steps, your iPad will restart and be running iOS 15. You might need to enter your passcode or Apple ID to finalize the setup.
