Samsung Galaxy Z TriFold review: specs, battery & used prices

Summary

Samsung's Galaxy Z TriFold is the most ambitious folding phone in the catalog: a 10-inch, three-panel OLED that opens into a small tablet, driven by the Snapdragon 8 Elite and sealed to IP48. At $2,899 new for the 16/512 configuration it is also the most expensive phone we track, and the laws of physics show in the numbers — 309 g of weight and an everyday score of 100/100 for what it does when open, against a compactness score of just 18/100. This is a productivity device first and a phone second.

Display and design

The main draw is the 10-inch 120 Hz OLED with a rated peak brightness of 1,600 nits — genuinely usable as a split-screen workspace. Our screen score of 72/100 is held back not by quality but by the constraints of a folding panel: creases, and a 45-degree-biased IP48 dust rating rather than full water sealing. At 309 g it is by a wide margin the heaviest device in the lineup; nobody will forget which pocket it lives in.

Performance

The Snapdragon 8 Elite is the fastest silicon available in any 2025 Android, and the TriFold uses it well: a gaming score of 79/100 puts it alongside conventional flagships, and the everyday score of 100/100 reflects how much windowed multitasking the big screen unlocks. Samsung commits to seven years of OS updates, so the platform will stay current long past the typical two-year ownership cycle.

Camera

The camera system is flagship-spec on paper — a 200 MP main sensor, 12 MP telephoto with OIS, and 10 MP ultrawide, with 8K30 video — but the 72/100 score tells the more honest story: this is very good imaging in a body that prioritizes the screen. Low-light output from the main camera is strong; the telephoto and ultrawide are conventional rather than class-leading.

Battery and charging

A 5,600 mAh battery split across the folding chassis keeps the lights on, with a battery score of 52/100 — respectable given how much display there is to feed. 45 W wired charging is the ceiling, with no bundled travel-friendly fast top-up beyond that. Heavy tablet-mode use will still find the charger by evening.

Verdict

The Z TriFold is a niche answered thoroughly: if a folding tablet-phone is what you want, nothing else in the catalog comes close, and resale demand for such a rare device keeps secondhand pricing firm and thinly traded. For everyone else, the same money buys a flagship phone plus a tablet with change to spare — at a third of the weight. Buyers prioritizing pocketability should simply look elsewhere; our compactness score of 18/100 is not a rounding error.
