The new iPhone system will only be available on models from iPhone 6S. Apple has decided to stop supporting iPhone 6 and older phones. Newer devices, including the iPhone XS and XR, released in 2018, may also download the update, which features dark mode, privacy enhancements, and redesigned native apps.
Another long-awaited feature is dark mode, which leaves the entire operating system interface based on dark colors such as black and gray, preserving the user's vision and saving energy. In addition, iOS 13 promises faster apps with smaller updates and installer files, as well as new native apps like the new Search, which merges the old "Search My iPhone" and "Friends" into one program.
