CUPERTINO, CALIFORNIA Apple today announced iPhone 17e, a powerful and more affordable addition to the iPhone 17 lineup. At the heart of iPhone 17e is the latest-generation A19, which delivers exceptional performance for everything users do. iPhone 17e also features C1X, the latest-generation cellular modem designed by Apple, which is up to 2x faster than C1 in iPhone 16e. The 48MP Fusion camera captures stunning photos, including next-generation portraits, and 4K Dolby Vision video. It also enables an optical-quality 2x Telephoto — like having two cameras in one. The 6.1-inch Super Retina XDR display features Ceramic Shield 2, offering 3x better scratch resistance than the previous generation and reduced glare.1 With MagSafe, users can enjoy fast wireless charging and access to a vast ecosystem of accessories like chargers and cases. And when iPhone 17e users are outside of cellular and Wi-Fi coverage, Apple’s groundbreaking satellite features — including Emergency SOS, Roadside Assistance, Messages, and Find My via satellite — help them stay connected when it matters most.2
