The ultra-thin smartphone trend is back, and these two are its main representatives. The difference in thickness is 0.16 mm, in weight - 2 g. So in the hand they are almost the same. Inside, though, they are not at all.
Short answer
Galaxy S25 Edge - a second ultra-wide module, a 200 MP main camera, stereo speakers, two SIMs and a QHD+ display. iPhone Air - a faster and more efficient chip, a brighter display, titanium and the Apple ecosystem.

Design
Almost identical in feel. The iPhone has a titanium frame, the Samsung a slightly bigger screen. Both are so thin that with a case they become "normal" - so if you buy them for thinness, use a thin case or none at all.
Cameras
Samsung has two cameras - a 200 MP main and an ultra-wide. The iPhone has one, 48 MP. For photos Samsung offers more options; the iPhone traditionally has better video and a stronger front camera.
Sound and connectivity
Stereo speakers and two physical SIMs on the Samsung vs mono and eSIM-only on the iPhone. If you carry two SIMs, this matters.
Performance
The A19 Pro is newer and built on 3 nm N3P. The Snapdragon 8 Elite is very powerful but heats up in a thin body. In both, the thin body limits sustained load - neither is ideal for gamers.
Battery
Galaxy S25 Edge - 3900 mAh, iPhone Air - 3149 mAh. Both compromise in favour of thinness, so a power bank in your backpack won't hurt.
Verdict: who should buy which
- Photos with two cameras - Galaxy S25 Edge.
- Two SIMs and stereo - Galaxy S25 Edge.
- Video and selfies - iPhone Air.
