Battery life on the Samsung Galaxy S21 is solid, although it’s not a game-changing improvement over the S20, as the company may have led some to believe with its new Exynos 2100 chipset.

The majority of cases are compatible with wireless charging, however it’s worth noting certain protective cases which are extremely bulk or those which have a metal construction will not be compatible.The downgrade to the display is perhaps the most controversial change Samsung has made for the Galaxy S21, with the company switching to a lower-res Full HD+ screen than the Quad HD display available on 2020’s Galaxy S20. You’ve got four color choices at launch: Phantom Gray, Phantom White, Phantom Pink, and Phantom Violet (the shade you see pictured throughout this review) – we think Violet is the standout color here.

The chipset – we’ve tested the Exynos 2100 version of the phone – is also powerful, delivering some fantastic results in real-world use as well as in benchmarking software.The Galaxy S21 phones were the first devices to use either Qualcomm’s Snapdragon 888 (US) or Samsung’s own Exynos 2100 (just about everywhere else). Those were the latest generation of top-end chipsets when the S21 range launched, though they've since been superseded. Samsung has opted for a lower-spec screen than the one on the S20, with a Full HD+ 6.2-inch display, but it offers a 120Hz refresh rate for super-smooth scrolling and graphics, plusfantastic colors, and strong brightness levels – and we didn’t notice the lower resolution in most of our testing.

Glasstic is the company’s own name for the material, which as the name suggests is somewhere between plastic and glass. It doesn’t feel as premium as a glass rear, but the matte finish also means it doesn’t feel like cheap plastic either. If you already own a Samsung Galaxy S20, or if you can find that handset for a significant discount, you won’t want to opt for the Galaxy S21 – while the newer phone gains in some areas it loses in others, and overall there’s not much between the two phones – certainly not enough to justify paying a couple of hundred dollars or pounds more.In the S21 both chips are paired with 8GB of RAM – if you want more than that on an S21 series device, you’ll want to opt for the Galaxy S21 Ultra, which comes with either 12GB or 16GB. One thing missing is compatibility with Samsung’s 45W chargers that worked with the S20 series. Samsung told TechRadar that it’s made optimizations to the 25W charging capabilities of its new phones, so 45W charging wasn’t that significant a benefit.
