Samsung Galaxy Z Fold 8 vs Samsung Galaxy S25 Ultra

Buy the Galaxy S25 Ultra if you want one durable, conventional phone with the best camera hardware, a brighter screen and a bigger battery. Buy the Z Fold 8 if the 7.6-inch inner screen and true multitasking matter more than camera reach. The S25 Ultra has the far larger track record, with 179,000 ratings at 4.7 versus 5,042 at 4.9 for the Fold. The Fold's hinge and inner display are the parts that wear; the Ultra's slab build has fewer moving parts.

  • Choose the Galaxy Z Fold 8 if you want a phone that opens into a 7.6-inch screen for split-screen work, reading and video, and you accept a heavier, more delicate device.
  • Choose the Galaxy S25 Ultra if you want the strongest camera set, a 6.9-inch screen that peaks at 2600 nits, and a 5,000 mAh battery in a phone that folds flat and takes a case.

Prices

Questions and answers

Which is better for multitasking?
The Z Fold 8. Its 7.6-inch inner screen runs two or three apps side by side, which the S25 Ultra's 6.9-inch slab cannot match.
Which has the better camera?
The S25 Ultra. Its 200 MP main sensor and full lens set beat the Fold's 50 MP wide and ultra wide pair, especially for zoom.
Which lasts longer?
The S25 Ultra has fewer moving parts, so its hinge-free build is the safer long-term bet. The Fold's hinge and inner screen are the parts to watch.
Is the Fold worth stepping up to?
Only if you will use the big screen daily for work or reading. If you mostly shoot photos and want battery life, the S25 Ultra gives more per dollar of hardware.
Which is easier to carry?
The Fold is lighter at 7.09 oz and folds to a narrower shape. The S25 Ultra is a wider, heavier slab.
Do both support wireless charging and 5G?
Yes. Both are unlocked 5G phones with wireless charging, fingerprint security and USB-C.
