Our Samsung Galaxy S23 Ultra Review

Galaxy S23 Ultra: Design & Display

The Galaxy S23 Ultra is a premium smartphone that has an elegant and sleek design, with a large and vibrant display. The phone has a slim profile and a glass back with a matte finish, which not only adds to its aesthetic appeal but also makes it easier to grip.

The phone comes with a 6.9-inch Dynamic AMOLED display with a resolution of 3200x1440 pixels. The screen has a high refresh rate of 120Hz, which ensures that all the animations and transitions are incredibly smooth. The display is also HDR10+ certified, which means that it can produce a wider range of colours and offer a more immersive viewing experience.

Galaxy S23 Ultra: Camera

The Galaxy S23 Ultra is home to an impressive quad-camera setup, consisting of a 108MP primary sensor, a 16MP ultra-wide lens, a 10MP periscope telephoto lens with 10x optical zoom, and a 3D Time of Flight sensor.

One of the most notable features on the Galaxy S23 Ultra's camera is its 10x optical zoom, which allows you to capture distant subjects with remarkable clarity and detail. The periscope telephoto lens also supports 100x digital zoom, although the quality can be a bit hit or miss.

The camera also comes into its own in low-light conditions, thanks to its large sensor and advanced image processing algorithms. The Night mode feature can capture stunningly detailed and well-exposed shots even in almost pitch-black environments.

Galaxy S23 Ultra: Battery life & Performance

The Galaxy S23 Ultra has a powerful battery life that can last up to 24 hours on a single charge. The 5000mAh battery ensures that you can use your phone for extended periods without having to worry about running out of juice. The phone also comes with a fast-charging feature that can recharge the battery in no time.

The performance of the Galaxy S23 Ultra is impressive, thanks to its Snapdragon 895 processor and 12GB of RAM. This allows for seamless multitasking and smooth performance even when running demanding applications. The phone also comes with 5G support, which makes browsing and streaming extremely fast.

Galaxy S23 Ultra: How much is it?

The Galaxy S23 Ultra comes with a pretty hefty price tag, but it's not surprising considering the premium features and cutting-edge technology it offers. The base model of the device is expected to start at around £1,249 making it one of the most expensive smartphones on the market.

However, for those who can afford it, the Galaxy S23 Ultra's cost is justified by its high-quality camera system, powerful performance, and expansive display. Additionally, the phone's 5G capabilities and other innovative features make it a worthy investment for those who want the latest and greatest technology.

Galaxy S23 Ultra: Verdict

The Galaxy S23 Ultra is a top-of-the-line smartphone that offers an impressive array of features, making it a solid choice for power users who demand the best in performance, camera quality, and design.

Its large, vibrant display, powerful processor, and ample storage capacity makes it a pleasure to use for both work and play, while its exceptional camera system captures stunning photos and videos that rival those of professional-grade cameras.

The S23 Ultra’s sleek and durable can withstand daily use and accidental drops. However, its high price point may be a drawback for some consumers, and its size and weight may be a downside for those looking for a more compact device.
