ORIGINAL STORY

Rumors suggest the tech giant will unveil three smartphones at its Wednesday event: an iPhone XS, a Plus model, and a third option with a more affordable price tag.

Apple may have already leaked details on the names of the iPhones on its website, reports The Verge. The names are iPhone XS, iPhone XS Max, and iPhone XR.

As with previous years, the next iPhone will likely get upgrades in its processing speed and camera, as well as an update to the iOS operating system. That update will also be available on select models of Apple's iPhone, iPad and Apple Watch.

Among the changes coming to iOS 12: a Screen Time feature allowing users to monitor how they use their mobile devices, better tools for managing notifications, and the ability to FaceTime with a group of people.

Based on operating system, Apple holds a 45.1 percent share of U.S. smartphones users, according to research firm eMarketer, compared to 53.3 percent for Google's Android. This year, 102.4 million people will own an iPhone, up 5.1% from the year before, said eMarketer.
