Samsung Galaxy Z Fold 4 review: specs, battery & used prices

Summary

The Galaxy Z Fold 4 is the book-style foldable at its most polished-for-2022: a 7.6-inch 120 Hz interior display, Snapdragon 8 Plus Gen 1, a proper 50 MP main camera, and IPX8 sealing at 263 g. Our everyday score of 89/100 is among the highest in the catalog — this is a genuine two-device replacement — but the battery and charging scores (28 and 7) recall that tablet screens are hungry. Note that Samsung's four-year update window has effectively reached its end, which the used pricing already reflects.

Display and design

The 7.6-inch interior OLED at 120 Hz is the reason to buy: split-screen work, full-width reading, real multitasking. The rated 500-nit peak is the honest weakness — indoor tool, outdoor compromise — and the 56/100 screen score balances the two. At 263 g and a compactness score of 44/100, it is a two-hands-always device with IPX8 water resistance.

Performance

The Snapdragon 8 Plus Gen 1 holds up well: everyday 89/100, gaming 32/100 — enough for high-settings mobile gaming on the big screen, and more than most 2022 foldables offered. Multitasking is where the chip and the display multiply each other.

Camera

A 50 MP main with OIS, 12 MP telephoto and 12 MP ultrawide, plus 8K24 video — the first Fold generation that did not ask you to apologize for its cameras. The 43/100 score is solid mid-flagship territory: strong main camera, conventional companions.

Battery and charging

A 4,400 mAh battery split across both halves feeds 7.6 inches of OLED; 28/100 endurance and 25 W charging mean planning around a charger for heavy days. This remains the tax on the form factor.

Verdict

Used supply is the deepest of any foldable we track: 12/256 units cluster near $300 (twelve listings), 12/512 near $349 (seven), and the rare 12/1024 near $369 (two). That is roughly a sixth of launch pricing for a device that debuted at $1,800 — but buy it as a discounted multitasking tool with an expiring software runway, not as a long-term platform. The Fold 5 adds a year of updates and a slimmer hinge for noticeably more money; the Fold 3 undercuts it but gives up the better camera.
