iPhone Duo vs Samsung Galaxy Z Fold 8: Every difference that you wanted to know

Apple finally made a foldable. Meet iPhone Duo. This new iPhone, launching alongside the iPhone 18 Pro and iPhone 18 Pro Max, looks stunning. It is a top-end phone with top-tier pricing too. In India, the iPhone Duo starts at an eye-watering Rs 3 lakh. Its closest—and biggest—competitor Samsung Galaxy Z Fold 8 is relatively cheaper. It is top tier too in every sense of the word.And so, needless to say, people who are out in the market looking to buy a folding phone will be curious to know what is so special about the iPhone Duo. Before we get into the nitty-gritties, you must know that the Duo is not available for buying just yet. It will go on sale in late October. The Fold 8 meanwhile is available for buying now. Without further ado, let’s dig in and find out how the two stack up against each other in terms of specs, features and pricing.iPhone Duo vs Galaxy Z Fold 8: DesignStarting with the Galaxy Z Fold 8, first thing, it is lighter of the two by a fair margin. It weighs 201g, which is why Samsung calls it the world’s lightest folding phone. It is built with a Flex Titanium chassis and an Armour FlexHinge. It’s also remarkably slim: 4.5mm unfolded and 9.7mm folded, which Samsung says makes it the flattest fold it has ever built. The cover screen measures 5.5 inches in a 16:10 ratio, closer to a regular phone's proportions.The iPhone Duo is a bit heftier in comparison. It weighs 254g when open, uses a Grade 5 titanium frame and hinge cover, and pairs Ceramic Shield 2 on the front with Ceramic Shield on the back. Apple also rates it IP68 for dust and water resistance. Its outer display is a compact 5.4 inches, small enough that the closed Duo still feels like a normal iPhone in your pocket. Last thing, if you prioritise pocketability and slimness, the Fold 8 goes for it comfortably. If you'd rather have something that feels reassuringly dense and armoured, the Duo has the edge at least on paper.iPhone Duo vs Galaxy Z Fold 8: DisplayHere things become a little interesting, as both devices share the exact same 7.6-inch display size. But they are developed in a completely different way. Samsung has reshaped the Fold 8's inner screen into a 4:3 "content-native" aspect ratio. It's a 120Hz QXGA+ Dynamic AMOLED 2X panel with up to 3,000 nits of peak brightness.Apple goes wide instead of square. The Duo's 7.6-inch Super Retina XDR inner display is, per Apple, 50 percent larger than the one on the iPhone 18 Pro Max, and it also caps out at 3,000 nits of outdoor brightness, with ProMotion up to 120Hz and Always-On support. Apple has gone a step further by hiding the selfie camera entirely underneath the display, so there's no punch-hole breaking up the screen, plus a nano-texture coating that visibly lightens the crease.It seems both companies are fighting over the same thing and that is how to keep the large folding screen feeling premium and they have answered it differently. Where Samsung reshaped the canvas, Apple hid the camera and smoothed out the fold line.iPhone Duo vs Galaxy Z Fold 8: ProcessorHere comes the Apple silicon vs Qualcomm silicon story. The Duo runs on Apple's new A20 Pro, built on a 2-nanometre process with a six-core CPU, seven-core GPU and a dual 16-core Neural Engine, alongside up to 50 per cent more memory bandwidth than the previous generation. Apple has also added a custom vapour chamber cooling system, likely to stop all that extra screen real estate from throttling performance.The Fold 8 runs Qualcomm's Snapdragon 8 Elite Gen 5 for Galaxy instead, paired with up to 16GB of RAM and as much as 1TB of storage on the top-end model.Both chips sit at the very top of their respective ecosystems, so this one probably comes down to whether you trust iOS or Android to squeeze more out of the silicon, not which spec sheet looks bigger.iPhone Duo vs Galaxy Z Fold 8: CameraThe Duo uses a 48-megapixel Dual Fusion system: a 48-megapixel Fusion Main camera that doubles as a 2x optical-quality zoom, plus a 48-megapixel Fusion ultra-wide with a 120-degree field of view. There's no dedicated telephoto lens. What Apple does offer is a neat foldable-only trick, prop the Duo up using its outer display as a viewfinder, and use the sharper rear cameras to take selfies instead of a front camera.Samsung keeps things similarly restrained on the Fold 8, sticking with a dual 50-megapixel camera setup rather than the elaborate triple-camera system found on the Fold 8 Ultra.iPhone Duo vs Galaxy Z Fold 8: BatteryBattery comparison is tricky as Apple and Samsung report battery life so differently.The iPhone Duo uses a dual-battery architecture and skips a capacity figure altogether. Apple claims up to 31 hours of video playback using the inner display, and up to 44 hours if you stick to the outer screen. It can also hit 50 per cent charge in around 20 minutes with a fast wired charger.The Fold 8 carries a 4,800mAh battery with 45W fast charging, a number Samsung states upfront rather than translating into hours of use.iPhone Duo vs Galaxy Z Fold 8: Price and availabilityThe Galaxy Z Fold 8 starts at Rs 1,79,999 for the 12GB/256GB model and climbs to Rs 2,39,999 for the 16GB/1TB version. The iPhone Duo, meanwhile, starts at almost Rs 3 lakh in India, meaning even Samsung's most expensive Fold 8 configuration works out roughly Rs 60,000 cheaper than where the Duo begins. In fact, the Duo's starting price sits above even Samsung's more premium Fold 8 Ultra, which tops out at Rs 2,59,999.So this isn't really a Fold 8 vs Duo decision on price, it's whether you want Samsung's lighter, more affordable wide-screen fold, or you're willing to pay a genuine premium for Apple's first take on the format, whichever Samsung tier you happen to be mentally weighing it against.- EndsPublished On: Sep 10, 2026 10:22 IST
