The launch of iPhone Duo is a big deal. This is the first ever foldable developed by Apple, and for that reason alone it has the chance to dethrone Samsung as the king of the foldable phone space. But it also helps that Apple has produced a phone with a lot of great qualities, and will naturally lead to comparisons with the Samsung Galaxy Z Fold 8.
The two phones are similar in a bunch of ways, including their wider, passport-inspired design. However, there are a number of key ways Apple has improved on the foldable design, and beaten Samsung at its own game. Considering this is Apple's first foldable, that might just make the extended development time worth it.
Here are seven ways iPhone Duo actually beats the Galaxy Z Fold 8.
IP68 rating
Google proved that a foldable could get an IP68 water and dust resistance rating with last year's Pixel 10 Pro Fold. This means that, despite all the moving parts around the hinge, Google was able to seal the phone up and ensure dust and other foreign particles can't get inside. Apple continued that trend by also sealing the iPhone Duo up to the same IP68 standard.
Meanwhile the Galaxy Z Fold 8 is only rated to IP48. The 8 means that it's water-tight, capable of being submerged in up to a meter of water for up to 30 minutes — just like Google and Apple. However, the 4 means that the Z Fold 8 offers no protection against dust, or any other particles larger than one millimeter (0.04 inches).
In other words, there's a whole bunch of nasty stuff that could get inside the Z Fold 8 and cause problems — and you might not even realize it. In other words, you should be able to take the iPhone Duo to the beach.
Apple Pencil support
Samsung used to sell foldables that supported the S Pen stylus, but the last one to be released was 2024's Galaxy Z Fold 6. From the Z Fold 7 onwards, Samsung stripped out the S Pen functionality, removing a critical part of the display makeup in order to reduce the phone's thickness. This means that the Z Fold 8 does not support any kind of active stylus.
Meanwhile, the iPhone Duo not only offers stylus support, it's compatible with the Apple Pencil USB-C — which works with the majority of iPads still on sale. Samsung needed a special kind of S Pen for the foldable screen, but the iPhone Duo uses a stylus that you may already have.
It's the most basic Apple stylus on sale, and it lacks key features you'll find on the Apple Pencil Pro, but it's better than nothing.
MagSafe
Magnetic wireless charging is a rarity, in part because Apple had a stranglehold on it for so long. While Qi2 wireless charging does allow phones to add a MagSafe-style magnetic ring, Samsung has avoided doing this — preferring to utilize special magnetic cases instead. The Galaxy Z Fold 8 is no exception to this trend, despite offering all the other benefits of Qi2 charging.
Apple had no such issue adding MagSafe to the iPhone Duo, as it's done with virtually every iPhone released since the iPhone 12. Plus, despite the phone's unique shape and size, Apple confirmed that it is compatible with MagSafe accessories and chargers — meaning all your old MagSafe products should still fit.
Faster 60W charging
MagSafe isn't the only way iPhone Duo beats Z Fold 8 in the charging department. Apple's foldable also offers faster charging speeds, regardless of whether you use MagSafe or a plug-in charging cable.
Wired charging supports up to 60W speeds, which regains 50% charge in just 15 minutes. Meanwhile, wireless charging is capped at 25W. In comparison, the Galaxy Z Fold 8 offers 45W wired charging, and can regain 43% in 15 minutes. Wireless charging is also slightly slower at 20W, which puts it at a slight disadvantage to the iPhone.
Better front-facing camera hardware
Like the S Pen, Samsung used to offer an under-display camera on Galaxy Z Fold phones — and it hasn't been seen since the Galaxy Z Fold 6. The quality was not great, and it was no surprise that later Z folds switched back to the hole-punch camera design. Apple is giving under-display camera tech another chance at the limelight.
Apple hasn't specified the quality of this camera, noting that it's designed for use with FaceTime and other video calling software rather than selfies. That suggests the quality isn't great. But at least Apple is willing to try new things with the Duo, rather than reusing the same lackluster selfie camera hardware for multiple years in a row.
Plus, the iPhone Duo's actual selfie camera, which is in the cover display, offers higher resolution than Samsung. We're talking 18MP compared to 10MP, and while resolution doesn't automatically mean quality, it's likely that this is a similar selfie camera to the one in iPhone 17 Pro Max — which I found to take better photos than the Galaxy Z Fold 8 Ultra.
iPhone Duo software reacts based on folded hinge state
A lot of Samsung phones offer what the company calls "Flex Mode," which allows the phone to react and adapt depending on the angle of the central hinge. Samsung Galaxy Z Fold 8 is the first Galaxy foldable to ditch this feature, despite the fact it's available on the Ultra model. This reduces the functionality of the phone somewhat, especially compared to iPhone Duo.
Apple doesn't have a special name for this feature, but the Duo does react depending on the angle of the hinge and the state of the fold itself. So if you have Netflix running, folding the screen to a 90-degree angle will shift the video to one side of the screen, and media controls to the other.
Vapor chamber cooling
The iPhone Duo offers an A20 Pro chipset with vapor chamber cooling, which helps dissipate heat. This means that the iPhone should offer better sustained performance, especially when doing resource-heavy tasks like gaming, multitasking and AI processing.
We haven't done any performance or thermal testing on the iPhone Duo just yet, so we don't know how effective the vapor chamber will be. That said, the Fold 8 doesn't offer a vapor chamber at all.
