Samsung Rethinks the Galaxy Z Fold: How the Fold8 Differs From the Fold7

For the first time Samsung is selling two book-style foldables side by side, and the Galaxy Z Fold8 is the more surprising of the pair. Instead of repeating the shape of its predecessor, the company turned the body sideways: folded, the phone is shorter and wider, and unfolded it feels closer to a small wide-screen tablet than to a tall book. The familiar proportions of the Galaxy Z Fold7 live on in a separate model, the Galaxy Z Fold8 Ultra, so comparing the two generations is no longer a matter of listing upgrades.

A new body and screen geometry

The Galaxy Z Fold7 was built around a tall frame with an 8-inch inner screen and a narrow 6.5-inch cover display in a 21:9 ratio. The Galaxy Z Fold8 follows a different idea. Its main screen is smaller at 7.6 inches, but the 1848 × 2448 resolution gives it near-tablet proportions, so video and web pages fill much more of the panel. The cover display shrinks to 5.5 inches, yet it becomes noticeably wider, which makes typing on the closed phone easier.

The change in proportions shows up in the measurements as well. Folded, the Galaxy Z Fold7 measures 158.4 × 72.8 × 8.9 mm, while the Galaxy Z Fold8 comes in at 123.9 × 81.9 × 9.7 mm. The newer model is much shorter and slips into a pocket more easily, though it is wider and slightly thicker when closed. Weight drops from 215 to 201 grams, and peak brightness on the main display rises from 2,600 to 3,000 nits, which matters most in direct sunlight.

The main screen of the Galaxy Z Fold8 uses a new Flex Titanium structure with a titanium layer beneath the flexible panel. According to the manufacturer, it makes the display stiffer around the crease.

Performance and battery life

The Galaxy Z Fold8 runs on the Snapdragon 8 Elite Gen 5 for Galaxy with a peak clock of 4.74 GHz, while the Galaxy Z Fold7 uses the Snapdragon 8 Elite for Galaxy at up to 4.47 GHz. Memory configurations stay the same across both generations, with 12 GB of RAM on the 256 and 512 GB versions and 16 GB on the 1 TB model.

The bigger change concerns power. Battery capacity grows from 4,400 to 4,800 mAh, and wired charging jumps from 25 to 45 W, while wireless charging moves from 15 to 20 W. For the Galaxy Z Fold line this is the first meaningful step in that area for several generations, since slow charging was regularly named as the weak point of earlier models.

Samsung states that 45 W charging refills the Galaxy Z Fold8 to roughly 63% in 30 minutes when a compatible adapter and a 3 A cable are used.

Cameras: fewer modules than before

Photography is where the Galaxy Z Fold8 falls behind last year's model. Its camera array has two modules: a 50 MP wide camera with optical stabilization and a 50 MP ultra-wide with a 120-degree field of view. The Galaxy Z Fold7 carries three, including a 200 MP main sensor and a dedicated telephoto with 3x optical zoom.

The practical gap shows up mostly at distance. The Galaxy Z Fold7 reaches 3x without losing detail and offers Space Zoom up to 30x, while the Galaxy Z Fold8 stops at 2x optical-quality zoom and 10x digital. Selfie hardware is identical, with 10 MP cameras on both the cover and the main screen. Video is the one area where the newer phone pulls ahead, recording 4K at up to 120 frames per second against 60 on its predecessor.

Software and support

The Galaxy Z Fold8 ships with Android 17 and One UI 9, while the Galaxy Z Fold7 launched on Android 16 and One UI 8. Both phones support Samsung DeX and the full Galaxy AI toolset, and the only wireless upgrade is Bluetooth 6.0 in place of 5.4. Wi-Fi 7, NFC and UWB are present on both generations.

Samsung promises seven generations of Android updates and seven years of security patches for both models, so the Galaxy Z Fold7 will keep receiving new system versions for years to come.

Who should upgrade from the Galaxy Z Fold7

The move makes sense for anyone who values a compact folded shape and a wide screen for video, reading and browsing. Those buyers also get a larger battery, far quicker charging and a newer chipset, all at a lower starting price than last year.

If photography or a large inner screen is the main reason to own a foldable, the case is much weaker. The Galaxy Z Fold7 keeps its 200 MP camera, its telephoto lens and its 8-inch display, and it remains the stronger device on those counts. Anyone who wants the familiar tall shape together with the new hardware has the Galaxy Z Fold8 Ultra instead, though that model sits at a higher price tier.
