Updating the software on your iPhone 6 is essential for maintaining security, stability, and access to the latest features. While this device represents an earlier generation of Apple hardware, it remains capable of running recent versions of iOS with proper preparation. This guide walks you through the entire process, ensuring a smooth and successful update.
Preparing Your iPhone 6 for the Update
Before initiating the download, you must verify that your device meets the necessary requirements. The iPhone 6 is compatible with iOS 12, which is the final major version supporting this hardware. Attempting to install newer versions like iOS 13 or later is not possible and will result in an error. Ensure your battery level is above 50% and connect to a stable Wi-Fi network to avoid interruptions or data charges.
Backing Up Your Data
Protecting your information is the most critical step in the update process. You should back up your device immediately before installing any software. This safeguards your photos, messages, app data, and settings in case something goes wrong. You have two primary methods for creating a backup, each offering distinct advantages depending on your preference.
iCloud Backup: Navigate to Settings > [your name] > iCloud > iCloud Backup and select "Back Up Now." This method is wireless and convenient.
iTunes/Finder Backup: Connect your phone to a computer using the Lightning cable, open iTunes (or Finder on macOS Catalina and later), and select "Back Up Now." This creates a local copy on your computer.
Checking Available Storage Space
iOS updates require a significant amount of temporary storage to download the firmware and install the files. The iPhone 6 typically needs several gigabytes of free space to complete the process. If your storage is full, the update will fail, and you will receive an error message regarding insufficient space.
To check your current storage, go to Settings > General > iPhone Storage. Here, you will see a visual breakdown of what is taking up space. To proceed, you must either delete unwanted apps, photos, or videos, or offload unused apps to reclaim space without deleting your documents and data.
Downloading and Installing the Update
Once your device is prepared, the actual installation is straightforward. With your phone connected to Wi-Fi and plugged into a power source, follow these steps to initiate the update.
Open the Settings app on your home screen.
Tap "General" and then select "Software Update."
Your phone will check for an available update. If iOS 12 is ready, you will see the version number and an option to "Download and Install."
Enter your passcode if prompted and tap "Download" again to confirm.
The download may take some time depending on your connection speed. It is crucial that the phone does not lock or run out of power during this phase. Once the download completes, you will be prompted to install the update, which will restart your device.
Troubleshooting Common Issues
Occasionally, users may encounter obstacles that prevent the update from proceeding. If the Software Update screen shows a message saying "Unable to Update," specific actions can resolve the problem. A network error might be resolved by switching Wi-Fi networks or toggling Airplane Mode on and off.
If the installation gets stuck on the "Slide to Update" screen, a force restart is often the solution. For the iPhone 6, you must press and hold both the Sleep/Wake button and the Home button simultaneously until you see the Apple logo. This clears the device's RAM and interrupts the update process, allowing you to attempt the installation again.
