Phone Opinions Review

Samsung Galaxy S21 Ultra 5G is one of those devices that tries to pack a lot into one package. Let us see if Samsung has managed to put together a phone that is actually worth your money. Announced in 2021, January 14, it arrives at a time when the competition is as tight as ever.

Design & Display

Up front there is a 6.8 inches, 112.1 cm 2 (~89.8% screen-to-body ratio) screen, pushing a resolution of 1440 x 3200 pixels, 20:9 ratio (~515 ppi density), and in real-world use it looks bright, crisp and easy on the eyes. It is not trying to reinvent the wheel with its design, but it does look the part. You can pick it up in a few finishes, including Phantom Black.

Performance & Software

At the heart of it sits the Exynos 2100 (5 nm) - International Qualcomm SM8350 Snapdragon 888 5G (5 nm) - USA/China, paired with 8GB of RAM, which means smooth scrolling, quick app switching and no real hiccups in normal use. It runs Android 11, up to 4 major OS updates, One UI 7 out of the box, so the software experience feels current.

Camera

The camera setup is one of the talking points here, with a 108 MP sensor doing the heavy lifting. Point-and-shoot results are reliable, and that is exactly what most buyers want.

Battery

Keeping the lights on is a Li-Ion 5000 mAh cell, and that is a healthy number that keeps range anxiety at bay.

In day-to-day use it feels like the kind of device you can rely on, whether you are replying to messages, scrolling through social media, watching videos or taking the odd photo. You could nitpick a few things, as you can with any phone in this bracket.
