5G transforms iPhone with accelerated wireless speeds and better performance on congested networks. Now you can download huge files on the go or stream high-quality HDR movies. Without. All. The.

Forty percent more transistors rev up speeds while increasing efficiency for great battery life. And a new ISP powers Dolby Vision recording — something no pro movie camera, let alone any other phone, can do.
