(NLDO) - Before updating, iPhone users should prepare some necessary steps to ensure the iPhone runs smoothly during and after the upgrade.

Note before installing iOS 26

However, before updating, users should prepare some necessary steps to ensure smooth operation of iPhone during and after the upgrade - especially with older devices.

1. Check if the device is compatible or not

First, your iPhone must be on the supported list. Apple still maintains support for iPhone 11 and later (A13 chip and later). Note that artificial intelligence features are only available on iPhone 15 Pro, iPhone 16, and iPhone 17.

2. Back up data

Backing up will help avoid data loss if there is a problem during the update process. Users can back up on iCloud, by going to Settings, selecting your name, then going to iCloud => iCloud Backup and tapping Back Up Now.

Alternatively, users can back up on their computer by connecting their iPhone to their Mac/PC, opening Finder (on newer macOS), the Apple Devices app, or iTunes (if using Windows or older macOS).

3. Clean up memory

iOS 26 is quite heavy, requiring at least 20 GB of free space for a smooth installation. For example, delete unused apps; delete photos, videos , redundant files; clear app cache (Spotify, YouTube,...).

4. Update the application

Apps that are not updated may cause errors after updating to the new iOS. Go to the App Store, click your account icon, then select Update All.

Apple has released the official update of the iOS 26 operating system.

5. Charge the battery and prepare Wi-Fi

Make sure your battery is above 50% or plugged in when updating. A stable Wi-Fi connection will help download quickly and avoid interruptions.

6. Get familiar with the new feature

iOS 26 has a new “Liquid Glass” interface, a reworked Photos app, and features like call filtering and live translation.

7. Consider waiting a few more days

If you need your iPhone to run smoothly, you can wait for the minor patches (like 26.0.1) that Apple usually releases shortly after a major release. However, don't wait too long, as these patches often come with important security updates.

To update iOS 26, users can access Settings => General Settings => Software Update.

What's new in iOS 26?

iOS 26 is considered one of Apple's biggest upgrades, bringing a new Liquid Glass design language inspired by visionOS, applied synchronously across the ecosystem.

This update improves the interface of applications such as Camera, Photos, Safari, Phone, FaceTime and adds many outstanding features: call filtering in the Phone app, custom wallpaper and survey creation in Messages, and a dedicated Games app to manage and connect gaming experiences.

Additionally, Apple further integrates Apple Intelligence with tools like Live Translation (live translation), Genmoji (create new emojis from two available emojis), and Visual Intelligence (recognize on-screen content to look up or add events).

Services like Apple Music, Maps, and Wallet are also getting upgrades, promising a more comprehensive user experience.
