Apple just released iOS 11.3, a major update for iPhone and iPad, about three months after the release of iOS 11.2. The update brings ARKit 1.5 to offer even more immersive AR experiences to recognize and place virtual objects on vertical surfaces like walls and doors, and more accurately map irregularly shaped surfaces like circular tables for next-generation AR apps, iPhone Battery Health (Beta) to show battery health and recommend if a battery needs to be serviced. This feature is available in Settings -> Battery for iPhone 6 and later. As promised, it is now possible to disable Apple’s power management feature.
