Which one should you buy?
Either way you get the same thing from us: open-box, never used, in-hand stock shipped from Utah, USA with tracking, covered by a 30-day money-back guarantee. So it's purely about which fits you:
Pick the iPhone 17 Pro if you want the same 6.3-inch ProMotion screen, 48MP telephoto and 256GB for less, and you don't need the newest chip or the variable-aperture main camera.
Pick the iPhone 18 Pro if you want the A20 Pro chip with its 7-core GPU, the variable-aperture main camera, 4K60 Cinematic mode and Apple's longer video playback figure.
Common questions

The chip and the main camera. The iPhone 18 Pro has the A20 Pro (7-core GPU, dual 16-core Neural Engine) and a 48MP Fusion Main camera with variable aperture from ƒ/1.48 to ƒ/4.0. The iPhone 17 Pro has the A19 Pro (6-core GPU, 16-core Neural Engine) and a fixed ƒ/1.78 main camera. Screen size and resolution are the same.
Do these iPhones take a physical SIM card?

Apple lists up to 36 hours of video playback for the iPhone 18 Pro and up to 33 hours for the iPhone 17 Pro. Real-world battery life depends on how you use the phone.
