iPhone 13 vs iPhone 17: is a used 13 the smarter buy?
Everything that changed between the 13 and the 17, what it costs to have it, and whether a QDN Certified 13 with a 15-month warranty is the better deal.
The short answer
Apple sells the iPhone 17 new from $799. A QDN Certified 13 costs a fraction of that when in stock. For that you give up a newer chip, Apple Intelligence and the bigger screen. If none of those changes how you use a phone, the 13 is the smarter buy; it still runs the current iOS and comes with a 15-month warranty, which is longer than Apple's standard one year on the 17.

Apple’s launch price. Not sold by QDN.
What actually differs
Only the rows where the two phones are not identical. A tick marks the side that wins the row.
The 17 runs the A19, a generation ahead of the A15 Bionic. Day to day both feel quick; the gap shows in games, video export and how many years of iOS updates lie ahead.
17 wins
Only the 17 supports Apple Intelligence (writing tools, notification summaries, the smarter Siri). If that matters to you, it settles the choice.
17 wins
The 17 has the bigger screen, 6.3″ against 6.1″. Bigger is better for video and reading; smaller is easier one-handed.
17 wins
The 17 has a 120 Hz ProMotion display; the 13 is 60 Hz. Scrolling and animation look noticeably smoother at 120 Hz, and the always-on display comes with it.
17 wins
Cameras: the 13 has 12 MP main, 12 MP ultra wide; the 17 has 48 MP main, 48 MP ultra wide.
17 wins
The 17 adds the Camera Control button for opening the camera and adjusting exposure or zoom without touching the screen.
17 wins
Battery: Apple rates the 17 at up to 30 hours of video playback against 19 for the 13. On a used phone the listing's battery health matters as much as this number.
17 wins
The 17 charges over USB-C, the same cable as a MacBook or iPad; the 13 still uses Lightning.
17 wins
The 17 has the Dynamic Island; the 13 has the older notch.
17 wins
The 17 has the customisable Action button in place of the mute switch.
17 wins
The 17 supports Emergency SOS and Roadside Assistance via satellite; the 13 predates that feature.
