Apple is expected to release its first 5G iPhone next year. Here's everything we've heard about it so far.

Apple did away with Touch ID on its latest flagships in favor of Face ID, but there's a chance the company could bring its fingerprint scanning technology back next year. Barclays analyst Blayne Curtis believes Apple could integrate Touch ID directly into the iPhone's screen next year, as he wrote in a note obtained by MacRumors.

That could help the 2020 iPhone more directly compete with rivals like Samsung's Galaxy S10, which already boasts in-screen fingerprint recognition.

Other than 5G connectivity and an in-screen fingerprint sensor, another headlining feature in next year's iPhone is expected to be its camera. Apple is planning to outfit next year's iPhone with a more powerful, rear-facing, 3D camera to enable better augmented-reality performance, according to Bloomberg.

The new camera would be powered by a laser scanner, unlike the dot projection technology Apple currently uses for Face ID in the iPhone X family's front-facing camera. In addition to boosting the iPhone's augmented reality functionality, the new 3D camera could be used to take photos with greater depth, the report says.

Apple will reportedly shake up the iPhone's design yet again in 2020.

The company is expected to release two new 5G-enabled iPhones in 2020, likely to be successors to the iPhone XS and iPhone XS Max. But the new smaller-sized iPhone will have a 5.4-inch screen instead of a 5.8-inch display, which would make it noticeably smaller than the current iPhone XS. That's according to Kuo's latest predictions, which MacRumors and 9to5Mac recently reported.

The larger-sized iPhone is expected to get even bigger next year with a new screen that's 6.7 inches, compared to the iPhone XS Max's 6.5-inch screen. Apple will also likely release a new 6.1-inch iPhone in 2020 that wil be a follow-up to the iPhone XR, but that phone will not support 5G, according to Kuo.

This new size for Apple's iPhone XS sequel would make it smaller than today's version but still larger than the iPhone 8. That could make it a compelling choice for those who want a phone that's more compact than the iPhone XS but need a screen that's bigger than the iPhone 8's 4.7-inch display. Plus, since the iPhone 8 will be three years old by then, there's a good chance Apple won't be selling it anymore, leaving virtually no option for those who want a smaller iPhone. As such, the smaller new iPhone XS could fill that hole in Apple's lineup.

Apple's 2020 iPhones will likely inherit the new features we'll see this September. That means there's a good chance they'll have a triple-camera system and will support reverse wireless charging. That last feature would make it possible to charge an accessory like your Apple Watch or AirPods just by resting them on the back of your iPhone.
