The Galaxy S21+ 5G is the sensible middle child of Samsung's 2021 flagship range, and that makes it one of the better value refurbished buys in the line-up today. It takes the standard S21's camera system and internals and wraps them in a bigger 6.7-inch screen with a noticeably larger 4,800mAh battery, which is where most of the benefit lies. It also gets a proper glass back rather than the polycarbonate panel Samsung used on the smaller S21, so it feels considerably more premium in the hand for not much more money. The compromise Samsung made across the whole S21 family was dropping display resolution to 1080p, meaning the S21+ is less sharp than the S20+ it replaced, though at normal viewing distance the 120Hz smoothness matters more than the pixel count. The microSD slot is gone too. UK units run the Exynos 2100, which is capable but runs warmer than the Snapdragon version sold in the US. With its update window now closed, buy this for the screen, battery and build rather than as a long-term phone.
