LONDON

When Microsoft revealed a replacement to Windows 8, it skipped the number 9 and went straight to Windows 10. Apple’s iPhone 8 was followed by the iPhone X (pronounced “ten”). But Samsung refused to follow: The successor to its Galaxy S8 is the Galaxy S9 (and a larger S9 Plus), and it’s coming out in March.

The phone is critical for the company. Samsung needs to be better than the iPhone X in the eyes of consumers.

Here’s how they compare.

Photography and Video: Samsung has equipped the S9 Plus with two cameras: a wide-angle, and a telephoto (like the iPhone X) and both capture at a resolution of 12 megapixels (also like the iPhone X). But the big difference may come with low-light performance. When you take a picture with the S9, you actually capture 12 images simultaneously. It’s similar to how the iPhone X processes high-dynamic range photos, taking three images at different levels of light exposure to combine them to produce a richer, more balanced image.

Samsung’s decision to expand this technology in the S9 complements the physical camera lens, which has a wider aperture to let in more light — an f1.5 aperture compared to Apple’s f1.8.

Screen and Design: Most features are the same across S9 and S9+ models, aside from the camera system. But the latter version is larger: it uses a 6.2-inch display compared to the regular S9’s 5.8-inch offering. The large and small variants weigh 189 grams and 163 grams (a little under six ounces) respectively.

The iPhone X weighs 174 grams — right in the middle of Samsung’s two models. But the screen is one big difference. Apple’s famous “notch” atop the iPhone X’s display is not something Samsung adopted. Instead, the S9 screen is an uninterrupted rectangle.

Features and Security: Apple has never let customers expand internal storage of the iPhone with removable SD memory. But Samsung does with the S9. It’ll have 64GB built in, but it supports Micro SD cards with up to 400GB of additional capacity. Apple will sell you up to 256GB of internal storage when you choose an iPhone X, but after that you’ll need to rely on cloud-based file-hosting, such as iCloud or Dropbox.

Animated emojis: Samsung has also taken the idea of Apple’s animated emojis, which use the front-facing camera to let users animate facial features of a unicorn and more by moving their own face. Samsung is introducing a similar feature with the S9, but rather than using existing emojis it will let you create an avatar of yourself and animate that instead. These can be shared as videos of animated GIFs via email or text message.

Price: Apple’s iPhone X starts at $999 (Dh3,669) — $200 more than the iPhone 8. Samsung is also increasing the price of its flagship, bumping the S9 up $100, to $950 in the case of the Plus model.
