Microsoft’s Surface Duo arrives on September 10th for $1,399

Microsoft is launching its Surface Duo dual-screen Android phone on September 10, priced from $1,399. After months of Microsoft executives teasing the device on Twitter, the company is now allowing anyone to preorder the Surface Duo today in the United States. Preorders will be available at AT&T, Microsoft’s online store, and Best Buy. While Microsoft had revealed the design of the Surface Duo back in October, the company has kept the specs relatively secret.

The device includes two separate 5.6-inch OLED displays (1800 x 1350) with a 4:3 aspect ratio that connect together to form a 8.1-inch overall workspace (2700 x 1800) with a 3:2 aspect ratio. Unlike foldables like Samsung’s Galaxy Fold, the Surface Duo is using real Gorilla Glass, and the displays are designed to work in a similar way to multiple monitors on a Windows PC. One big question over the Surface Duo has been the camera.

Microsoft is using an 11-megapixel f/2.0 camera, which will include auto modes for low light, HDR multi-frame captures, and a “super zoom” up to 7x. Both 4K and 1080p video recording will be supported at 30fps and 60fps, with electronic image stabilization. There is only a single camera on the Surface Duo, which can be used both for video calls and as a main camera.

The basic Surface Duo hardware also consists of a Qualcomm Snapdragon 855, 6GB of RAM, and up to 256GB of storage.

LTE is available on T-Mobile, AT&T, and Verizon, but there is no 5G support at all. Microsoft is also shipping a bumper cover in the box, designed to protect the Duo. The company is also including two batteries in the Surface Duo, split beneath both displays. Overall there is 3577mAh of capacity, which is considerably less than the 4500mAh found on Samsung’s single-screen Note 20 Ultra and even the 4380mAh on the original Galaxy Fold.

Despite this, Microsoft is promising “all day battery life”, which means up to 15.5 hours of local video playback, up to 10 days of standby time, and up to 27 hours of talk time. The capacity here does leave a little cause for concern as the device is powering two screens, not one. It is probably one of the sexiest devices the company has ever built.

It does things that single-screen devices can not do, period. Microsoft’s vision for the Surface Duo is to improve productivity on the go, and it has also been doing some interesting work on the software side to compliment the hardware. Any Android app will run on the Duo without modification, thanks to the choice of two separate displays. Any app has to run, and it was obviously important to support everything Android from day one.

Developers can also optimize the layouts of their apps to really take advantage of the two displays and span across them.

Microsoft has tweaked its own apps like the Office suite and OneDrive to span the displays, and third parties like Amazon have also done work on the Kindle app to make it feel like you are reading a book by flicking pages across the two screens. The company is also using algorithms to predict how to open apps on different displays. There is an algorithm in there that is very smart and trying to be predictive.

If you are on one screen and you are invoking a link, it will fill the other screen. The end result is that if you click a link in an email app on one screen, it will open on the other so you can continue to read the email side by side with a webpage. Apps like Microsoft Teams and PowerPoint are also optimized so you can see a video call and the rest of your Teams chat, or look at a full slide and the rest of the deck simultaneously.

Microsoft has been working closely with Google on Android for the Surface Duo. It was a bit of a head scratcher. It initial days were interesting at first, and the partnership has been crazy fun. At first there is a little bit of getting to know each other, but then very quickly they saw what is right for their customers and what can be possible. It is great for Google and Android, and it is great for the company.

Microsoft had to go with Android for the pure reason of mobile apps, especially after Windows Phone failed in the market.

Microsoft has to light up on every platform. The company has created APIs for dual-screen apps to work in the Android codebase, and it plans to upstream them for other manufacturers and third parties to use. It is part of a broader push to make dual-screen and foldable devices a reality. Two screens are coming, they are needed. It will be interesting to see how developers adapt their Android apps here, and it is key to the overall success of dual-screen or foldable devices in general.

Price will be a sticking point for Surface Duo, just as it was for the Galaxy Fold and other devices that will try to usher in a foldable or dual-screen future. A lack of 5G and NFC, questions over battery life, and the camera quality will all need to be addressed, but Microsoft is clearly at the start of a future it believes in. You will have to pay a price to be part of that initially.

The real question will be how well Surface Duo, and devices like it, improve productivity on the go, and whether two mobile screens is truly needed. These devices will ultimately require some hardware advances to really pull off the vision. But if consumers agree with Microsoft, Samsung, and others that two screens are better than one, then we are witnessing the future being built.

If not, we are just witnessing unique attempts to try and reshape mobile devices. At the very least, mobile phones are suddenly getting exciting again.
