iPhone 15 Pro vs iPhone 17 Pro: is a used 15 Pro the smarter buy?
Everything that changed between the 15 Pro and the 17 Pro, what it costs to have it, and whether a QDN Certified 15 Pro with a 15-month warranty is the better deal.
The short answer
Apple sells the iPhone 17 Pro new from $1,099. A QDN Certified 15 Pro starts at $638, so you keep about $461 in your pocket. For that you give up a newer chip, the bigger screen and the newer cameras. If none of those changes how you use a phone, the 15 Pro 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 Pro.

What actually differs
Only the rows where the two phones are not identical. A tick marks the side that wins the row.
The 17 Pro runs the A19 Pro, a generation ahead of the A17 Pro. Day to day both feel quick; the gap shows in games, video export and how many years of iOS updates lie ahead.
17 Pro wins
The 17 Pro has the bigger screen, 6.3″ against 6.1″. Bigger is better for video and reading; smaller is easier one-handed.
17 Pro wins
Cameras: the 15 Pro has 48 MP main, 12 MP ultra wide, 12 MP telephoto; the 17 Pro has 48 MP main, 48 MP ultra wide, 48 MP telephoto.
17 Pro wins
The 17 Pro zooms to 4× optically; the 15 Pro stops at 3×. For concerts, sport and kids on a stage, the longer lens is the one you will use.
17 Pro wins
The 17 Pro adds the Camera Control button for opening the camera and adjusting exposure or zoom without touching the screen.
17 Pro wins
Battery: Apple rates the 17 Pro at up to 33 hours of video playback against 23 for the 15 Pro. On a used phone the listing's battery health matters as much as this number.
17 Pro wins
The 15 Pro has a titanium frame; the 17 Pro is aluminum.
Preference
The 15 Pro is lighter: 187 g against 206 g.
