Updating the iOS on an iPhone 6 is a straightforward process that ensures your device remains secure, efficient, and compatible with the latest apps. This older model, while no longer receiving major iOS version releases, can still update to the final supported release, and staying current is essential for performance and safety.
Preparing Your iPhone 6 for the Update
Before initiating the update, proper preparation prevents interruptions and data loss. You need to ensure that your device has sufficient battery life and a stable connection to Wi-Fi. Apple requires a power connection or at least 50% battery for the installation to begin, and a Wi-Fi link avoids consuming your cellular data plan during the download.
Check Available Storage Space
The iOS update requires a specific amount of free space on your internal memory. If the storage is insufficient, the update will not download. You should review your storage by navigating to Settings > General > iPhone Storage and deleting unnecessary photos, apps, or cached data to create room for the new system files.
Backing Up Your Data
Creating a backup is the most critical step to protect your information. If something goes wrong during the installation, a backup allows you to restore your apps, messages, and settings exactly as they were. You can back up directly to iCloud for remote access or to your computer via iTunes for faster, local storage.
Using iCloud Backup
To back up to iCloud, open Settings, tap your Apple ID, select iCloud, scroll to iCloud Backup, and toggle it on. Tap "Back Up Now" and wait for the process to complete. Ensure that your iPhone 6 is connected to Wi-Fi and remains plugged in until the backup finishes to ensure the archive is complete.
Using iTunes Backup
Connecting your phone to a computer provides an alternative backup method that some users prefer. Open iTunes on your Mac or PC, select your device when it appears, and click "Back Up Now." This method creates a copy of your data on your computer, which is useful if your internet storage is limited or unreliable.
How to Update iOS on iPhone 6
Once your device is prepared, you can begin the actual installation of the software update. This process downloads the firmware and installs it locally on the phone, replacing the current operating system with a newer, optimized version.
Over-The-Air (OTA) Method
The easiest way to update is over-the-air, which downloads the update wirelessly. Go to Settings > General > Software Update. If an update is available, you will see the option to download and install. Tap the option, enter your passcode if prompted, and allow the phone to download the file. The phone will restart automatically once the installation is complete.
Updating via iTunes
If you encounter issues with OTA updates, using iTunes on a computer can resolve them. Connect your iPhone 6 to the computer, open iTunes, and select the device icon. Click "Check for Update" and follow the prompts to download and restore the software. This method forces a fresh install, which can fix errors that occur during wireless updates.
