1. Basic Steps Before Updating the iPhone

Before starting the iPhone update, there are two main steps that form the first line of defense to protect your files and ensure the update process succeeds without errors:

First: Backup the iPhone

The backup is your safety net in case of any sudden internet interruption or device battery failure during the update, allowing you to easily restore all your photos, contacts, and applications:

• Via iCloud: Go to Settings > Tap on your Name > Select iCloud > Then iCloud Backup and tap Back Up Now.
• Via Computer (Mac or Windows): Connect the iPhone to the computer via the cable and use the Finder app on Mac or iTunes on Windows to create a local backup.

Second: Check Space and Network Connection

• Internet Connection: Always prefer connecting to a strong and stable Wi-Fi network since the size of major iPhone updates can exceed several gigabytes.
• Battery Percentage: Make sure the iPhone is plugged into a charger or that the battery is at least 50% charged.
• Available Storage Space: Open Settings > General > iPhone Storage. If the space is insufficient, it is recommended to delete unused applications or use the “Offload Apps” feature to free up the required space.
