The Galaxy S21 Ultra has the biggest screen of the three new S21 phones, stretching out across 6.8in. It’s one of Samsung’s “Dynamic AMOLED 2x” panels and it now supports 120Hz at the native WQHD+ resolution (1,440 x 3,200) of the panel. Let’s move to the numbers-heavy portion of this review, then. In the Geekbench 5 CPU test, the Galaxy S21 Ultra’s Exynos 2100 matched the single-core performance of its predecessor, the Exynos 990, found inside the S20 Ultra. Where it differs, however, is in multi-core performance. The S21 Ultra is roughly 24% faster here, which is a huge boost. The chip has improved battery life as a result - the Exynos 2100 has a 20 percent decrease in power consumption compared to its 7nm predecessor. The Samsung Galaxy S21 Ultra also has a telephoto lens. This 10-megapixel camera has 3x optical zoom. This is a sensible option for taking pictures of things that are far away, such as a sports event.

What else is new? Well, there's the Single Take 2.0 feature. This allows you to capture fast-changing scenarios by taking multiple photos and then selecting the best one. The Single Take 2.0 feature also records a short video clip of up to 10 seconds.This is also the first Samsung phone to launch without a charger in the box. Following in Apple’s footsteps, Samsung says the charger’s removal is an effort to reduce the environmental impact of the phone, but it also says that it “removes any pressure that consumers may feel towards continually receiving unnecessary charger accessories with new phones”.

Where the Galaxy S21 Ultra has seen the biggest improvement is in the graphics rendering department. With an average frame rate of 93fps in the GFXBench Manhattan on-screen test (at native WQHD resolution), the S21 Ultra’s GPU performance is almost double that of last year’s S20 Ultra. Drop the screen resolution down to FHD+ and the frame rate jumps to 118fps. First, you'll want to make sure that you're using the right charger. There are many different options, but most should work with Samsung devices. For example, the Aukey AirCore Wireless Charger is a good choice if you're looking for a wireless charger that supports wireless earbuds. Foned completely gets it, it's not easy trying to understand the differences of each mobile network operator. Is o2 any better than Vodafone for this smartphone, when it comes to coverage? Or worse? It's a real minefield. Another example, which is better? A Samsung Galaxy S21 Ultra ee contract or a Samsung Galaxy S21 Ultra Tesco Mobile contract? Bokeh Mode, Face Detection, HDR, AI Features, Smile Detection, Night Mode, Panorama, Portrait Mode, Automatic Mode, Burst Mode, Stereo Recording, Scene Detection, Slow Motion, Time LapseHang on to your power adapters. Neither the old USB-A nor the new USB-C chargers are included in the box, but you will get all-day battery life. (Image credit: Future) Samsung Galaxy S21 Ultra battery life
