iPhone Duo vs Galaxy Z Fold 8 Ultra

Samsung's Galaxy Z Fold 8 Ultra went on sale Aug 7, 2026, and Apple's iPhone Duo followed on Oct 23; as of Nov 12, 2026, they start at $2,099.99 and $1,999. On paper, the Galaxy Z Fold 8 Ultra is bigger, thinner, lighter and has a real telephoto camera, while the iPhone Duo counters with IP68 water resistance, Apple Pencil support, 25W magnetic wireless charging and a 2TB option.

More camera and more screen, or tougher and more Apple? Specs, prices and reviewer findings follow.

What the Ultra adds over the regular Galaxy Z Fold 8

Samsung sells two book-style foldables this year, and it styles this one as the Galaxy Z Fold8 Ultra. According to Samsung's first-look post, the Ultra moves to an 8-inch main display and a 5,000 mAh battery, while the standard Galaxy Z Fold 8 has a 7.6-inch main display, a 4,800 mAh battery and weighs 201 g to the Ultra's 215 g.

The bigger addition is the camera. Samsung's announcement lists a 10MP telephoto only on the Ultra, alongside a 200MP main camera, while the Galaxy Z Fold 8 pairs 50MP main and ultrawide cameras with no telephoto. The cover screen grows too, to 6.5 inches. The standard model is covered in iPhone Duo vs Galaxy Z Fold 8, so this guide sticks to the Ultra.

Price

As of Nov 12, 2026, Samsung's US store lists the unlocked Galaxy Z Fold 8 Ultra at $2,099.99 for 256GB, $2,299.99 for 512GB and $2,699.99 for 1TB. The iPhone Duo costs $1,999, $2,199 and $2,599 for the same tiers, plus $3,199 for 2TB, per MacRumors.

So the iPhone Duo is $100.99 cheaper at each shared tier, and only the iPhone Duo offers 2TB. Samsung's store prices can change with promotions. More on Apple's tiers in iPhone Duo price by storage tier.

Displays and the crease

The Galaxy Z Fold 8 Ultra has an 8.0-inch 2504 by 2256 main display and a 6.5-inch 1080 by 2520 cover display, both with a 1 to 120Hz adaptive refresh rate, per Samsung. The iPhone Duo has a 7.6-inch 1878 by 2670 inner display and a 5.4-inch 1398 by 2034 outer display, both ProMotion up to 120Hz, per Apple's spec page.

TechRadar's review found the Ultra's main screen nearly flat, with a crease that is much less visible but can still be felt. For the iPhone Duo, Wired called the crease hardly visible while PCMag said it still shows with the screen off, per Macworld's review roundup. More in the iPhone Duo crease explainer.

Weight and thickness

On weight and folded thickness, the Galaxy Z Fold 8 Ultra wins. Samsung lists 215 g, 8.9 mm folded and 4.1 mm unfolded (Samsung's unfolded figure excludes the screen frame), against 254 g, 11.3 mm closed and 5.2 mm open for the iPhone Duo, per Apple.

The iPhone Duo is shorter and wider, though: Apple lists a 117.8 mm height, where Samsung lists 158.4 mm for the Ultra. Reviewers split on whether the iPhone Duo's heft matters: in Macworld's roundup, 9to5Mac found it comfortable to carry, while Gizmodo said it made a front pocket sag. The size comparison tool shows the difference life-size.

Cameras: the telephoto gap

The Galaxy Z Fold 8 Ultra has a 200MP main camera, a 50MP ultrawide and a 10MP telephoto with 3x optical zoom, per Samsung. The iPhone Duo has a 48MP main and a 48MP ultrawide, and its 2x option is an "optical-quality" crop from the main sensor, according to Apple, with digital zoom up to 10x.

Neither zoom setup escaped criticism. TechRadar called the Ultra's 3x telephoto underpowered and wanted 4x or 5x, and Tom's Guide was harsher about it. On the iPhone Duo side, Tom's Guide called the missing telephoto a big deal for zoomed shots, per Macworld's roundup. Only the Galaxy Z Fold 8 Ultra has dedicated telephoto hardware. More in iPhone Duo cameras.

Chip, battery and charging

The iPhone Duo runs Apple's A20 Pro. The Galaxy Z Fold 8 Ultra uses the Snapdragon 8 Elite Gen 5 Mobile Platform for Galaxy, which TechRadar found handled demanding tasks with ease.

Battery figures don't line up neatly. Samsung lists a 5,000 mAh typical dual battery, while Apple lists dual batteries without a capacity and rates the iPhone Duo for up to 31 hours of video playback on the inner display. Tom's Guide measured 14 hours 33 minutes in its own Ultra battery test, which isn't comparable with Apple's rating. Apple's ratings are explained in iPhone Duo battery life.

On charging, Samsung says the Ultra reaches up to 67% in about 30 minutes with a 45W adapter, and supports 20W wireless charging. Apple says the iPhone Duo reaches up to 50% in around 20 minutes with a 60W-capable adapter, and supports MagSafe and Qi2 charging up to 25W. Tom's Guide notes the Ultra lacks magnetic wireless charging without a case.

Water resistance and stylus support

The iPhone Duo is rated IP68, up to 6 meters for 30 minutes, per Apple. The Galaxy Z Fold 8 Ultra is rated IP48, and Samsung's footnote bases that on submersion in up to 1.5 meters of freshwater for up to 30 minutes, and advises against beach or pool use. That gap matters if your phone spends time near water.

Neither the Galaxy Z Fold 8 nor the Ultra supports the S Pen, SamMobile reports, and TechRadar notes the Ultra's main screen has no digitizer layer. The iPhone Duo supports Apple Pencil (USB-C), without hover, per Apple; that support arrived in iOS 27.2, per MacRumors. More in Apple Pencil on iPhone Duo.

Software and updates

The Galaxy Z Fold 8 Ultra ships with Android 17 and One UI 9, per Samsung, and Samsung's Singapore spec page promises up to seven Android OS upgrades and seven years of security updates, depending on market and carrier. Apple hasn't said how many years of iOS updates the iPhone Duo will get.

Apps are the iPhone Duo's open question. Wired and Tom's Guide both saw phone-sized apps with black bars on the inner screen, per Macworld's roundup, though Wired expects that to fade as developers update. See the best apps for iPhone Duo.

Which should you buy?

TechRadar's Lance Ulanoff, reviewing the Ultra before the iPhone Duo shipped, wrote that he'd pick it "over the competition every single day." That holds up best for Android users: the Galaxy Z Fold 8 Ultra is the lighter, thinner foldable with the bigger screens and the only telephoto here.

If you already use an iPhone, Apple Watch and iCloud, the iPhone Duo is the more natural pick, and it costs $100.99 less per shared tier (as of Nov 12, 2026). It also suits anyone who wants a stylus, 2TB of storage, 25W Qi2 charging or the higher IP68 rating.

If zoom photography or a lighter phone ranks first, the Galaxy Z Fold 8 Ultra is the stronger buy, though it costs more and has the weaker water rating. Weighing Google's option?
