Apple iPhone Duo - Reviews and Specs

Apple iPhone Duo
This article compiles specifications, hands-on impressions, and expert reviews of Apple’s first foldable smartphone, the iPhone Duo. Reviewers praise its polished design, expansive displays, and optimized software while questioning its high price, durability, and competitive position.

Pros

+ Expansive dual OLED displays
+ Powerful A20 Pro processor
+ Generous storage configurations
+ Wi-Fi 7 connectivity
+ Optimized foldable iOS experience

Cons

- Extremely high launch price
- Heavy 254-gram design
- First-generation durability uncertainties
- Gaming performance appears limited
- Stylus support remains absent

The Apple iPhone Duo marks the company’s entry into the foldable smartphone market. It features a 7.6-inch OLED main display, a 5.4-inch cover screen, and a 120 Hz refresh rate. Apple equips the device with an A20 Pro processor, 12 GB of memory, up to 2 TB of storage, and iOS 27. Its camera system combines two 40 MP rear sensors with a 12 MP front camera. Early reviewers highlight its thoughtful design, familiar software, capable performance, and potentially subtle display crease. However, its substantial price, 254-gram weight, uncertain durability, and strong competition remain important concerns.

Apple's folding phone is finally (well, almost) here. The phone goes up for preorder on Oct. 16 and reaches stores on Oct. 23. That means you have until then to decide if the iPhone Duo is the right phone for you or if you should settle for the yearly refresh of the iPhone 18 Pro and Pro Max.

Samsung Galaxy Z Fold8 vs Apple iPhone Duo: Does Eight Generations Make a Difference?
Source: Tech ARP English
So, does eight generations make a difference? Yes, but it may not matter because Apple is entering the market after years of observing what worked in the market, and what didn’t. It also does not need to persuade existing iPhone users that foldables are useful from scratch.

iPhone Duo first impressions: a tale of two screens, and more
Source: 91mobiles English
Based on my limited time checking out the iPhone Duo, I can say that for me, the takeaway is how Apple is using the device’s form factor and folding capabilities to elevate the user experience via the UI. The Netflix app, the multitasking features, the little things that help make Standby so useful and interesting, even small things like the folding animation, all combine to make it a compelling device.

I Touched the iPhone Duo. And I Have Thoughts.

The iPhone Duo feels like a huge release for Apple. It’s not for everyone, and I have no doubt that some people will rush into buying it in a fit of excitement only to realise, a couple of months down the line, that it really isn’t for them. That’s what excites me, though.

I was mostly indifferent about the possibility of a foldable iPhone, especially as someone who’s been testing Android foldables for years, but based on my hands-on time so far, Apple seems to be doing a nice job making the whole experience both familiar for iPhone users and distinct from the swath of foldable options already out there.

Apple iPhone Duo vs Google Pixel 11 Pro Fold: differences to consider

So, two very different devices. Apple leaned heavily into the multimedia machine that's also extra smart. That's why it chose a wide screen, and it talked it up quite a lot during the presentation. Google, on the other hand, is on the main quest of making the smartest smartphone it can. Even if it can't crush 3D games.

iPhone Duo: Apple’s missed opportunity to do what Samsung couldn’t
Source: Tech Advisor English
Samsung has been in the foldable game from the beginning. It pretty much wrote the foldable book with its Fold series, which reached its eighth and best iteration recently with the Samsung Galaxy Z Fold 8. However, one thing it has seemed weirdly unwilling – or perhaps unable – to do is to properly implement its S Pen stylus system.

I’m not calling this the best foldable yet without further testing, but I’m definitely keeping an eye on this one. And for that price tag, it has to be top-notch. The iPhone Duo starts at C$2,999, making it the most expensive smartphone in the Canadian market, so it better be pretty stellar.
