According to Bloomberg's Mark Gurman in his Power On newsletter, all signs point to iOS 26 entering the public beta phase this week, likely on or around Wednesday, July 23, 2025. Apple confirmed a July public beta but gave no exact date.

Before upgrading to the iOS 26 Beta, there are several important points to keep in mind. First, make sure your iPhone has enough free storage—Apple recommends at least 15GB to ensure a smooth update. Second, update your device on a stable Wi-Fi network to avoid interruptions. Most importantly, always back up your data before upgrading, as beta versions can be unstable and may cause app crashes, system errors, or even data loss.

For backups, besides using iCloud or iTunes/Finder, we recommend using a professional tool like iMyFone D-Back. D-Back supports various backup methods and can help you recover lost data quickly if something goes wrong during the upgrade. Its powerful recovery features reduce the risk of data loss and keep your important information safe.

Note that iOS 26 Beta supports iPhone 11 and later models, including iPhone SE 2nd and 3rd gen. Some new features, like Apple Intelligence, require the latest iPhone 15 Pro or 16 series to work fully. Since beta versions may affect normal device usage—especially with banking apps or CarPlay—regular users should consider testing on a secondary device to avoid disruption.

In summary, before upgrading to iOS 26 Beta:

• Ensure at least 15GB of free storage
• Update on a stable Wi-Fi connection
• Back up your data thoroughly, using iCloud and tools like D-Back
• Check device compatibility and consider risks, preferably using a non-primary device for testing
