Samsung Galaxy Z Fold 8 vs. iPhone Duo: Which Fits Your Routine?

The Samsung Galaxy Z Fold 8 is the better fit for lighter handling and flexible multitasking. The iPhone Duo has the edge in several CPU and graphics benchmarks reported by Tom’s Guide, and in one battery test that outlet says it optimized for the Duo and ran on both phones at the same time.

For the launch context, see our earlier coverage of Apple’s iPhone Duo announcement. The choice here comes down to how you use a foldable day to day.

Tom’s Guide published its comparison on October 26, 2026. It lists these US starting prices and reports the specifications and test results summarized here:

Multitasking and DeX: more flexibility on the Fold 8

The Fold 8 gives you more ways to keep apps visible at once. Tom’s Guide says it supports up to three split-screen apps and as many as five floating windows. It also supports Samsung DeX, a desktop mode. The Duo’s reported setup places two apps side by side.

That difference matters if you regularly switch between several tasks or want to use a phone with an external display. One Fold 8 user described connecting an external display and using DeX to emulate retro games on a TV. It is a personal example of how that feature can fit into a routine, rather than a measure of how every game or display works.

App layout can affect the experience, too. A Reddit commenter who says they have used foldables since 2020 described the Duo’s side navigation and some app layouts as frustrating during a 24-hour trial, including in Readwise Reader. That account offers a specific example of the kind of interface friction to consider alongside the broader multitasking options.

Weight and screens: a lighter phone or different display qualities

The Fold 8 weighs 201 g, compared with 254 g for the Duo, a 53 g difference. Its listed thickness when open is also lower. If you carry a large phone throughout the day, the Fold 8’s lower weight may be a practical advantage.

Both phones have a 7.6-inch inner display. Tom’s Guide measured peak brightness at 2,558 nits on the Duo and 2,649 nits on the Fold 8. The comparison describes the Duo’s nano-texture as reducing glare and making the crease less noticeable, while its color saturation and contrast trail the Fold 8’s main display. It also describes an anti-glare coating on Samsung’s phone.

The measurements and observations point to different display priorities: the Duo’s matte texture may appeal if reflections and crease visibility bother you, while the Fold 8 measured brighter in Tom’s Guide’s comparison.

Performance and battery: the results depend on the test

Tom’s Guide’s October 26 comparison reports higher iPhone Duo scores in Geekbench 7’s single-core and multi-core tests and in 3DMark Solar Bay Unlimited. The Fold 8 scored higher in Geekbench AI 1.7, so the results do not put one phone ahead in every workload.

In Tom’s Guide’s new battery test, the Duo lasted 13 hours 20 minutes and the Fold 8 10 hours 6 minutes. The outlet says it optimized the test for the Duo and ran both phones simultaneously. It also reports an earlier Fold 8 result of 12 hours 19 minutes from a separate test, so the newer figure belongs to that particular run, not every use pattern.

In the same comparison’s charging checks, the Fold 8 gained 43% after 15 minutes and 70% after 30 minutes; the Duo gained 42% and 66% at those checkpoints. These are results from that comparison’s checks.

Cameras: scene-specific results, with no dedicated telephoto

Neither phone has a dedicated telephoto camera. Tom’s Guide lists a 48MP main and 48MP ultrawide rear camera on the Duo, and 50MP main and ultrawide cameras on the Fold 8.

Tom’s Guide favored the Duo overall in its sample comparisons, including low-light photos and outer-screen selfies. It also noted that some Fold 8 samples looked washed out. At 10× zoom, the Duo sample became softer and more pixelated, while the Fold 8 sample looked less blurry. That makes the reported advantage dependent on the scene, rather than a simple megapixel contest.

Which one fits your routine?

Tom’s Guide lists the US 256GB iPhone Duo at $1,999 and the 256GB/12GB Galaxy Z Fold 8 at $1,899, a $100 difference between those entry configurations. The price gap sits alongside a clearer practical split:

• Choose the Galaxy Z Fold 8 if lower weight, more flexible app windows, or DeX matter most.
• Choose the iPhone Duo if you prefer iOS and Apple ecosystem continuity, and value its reported results in the specific CPU, graphics, and battery tests described here.

Neither set of test results replaces the features you will use most: the Fold 8 offers broader windowing, while the Duo keeps two apps side by side.
