Connections sees the S21 support 4G, 5G, Bluetooth 5, 802.11ax WiFi 6, Near-Field Communication (NFC, used for pairing and Google Pay), Magnetic Stripe Technology (MST, used for Samsung Pay), and a wired Type C USB connection at the bottom. The S21 and S21+ have similar camera setups to their predecessors but benefit from improved software and image processing. Both have a 12 MP wide sensor, a 64 MP telephoto sensor with 3x hybrid zoom, and a 12 MP ultrawide sensor. The S21 FE also has a similar camera setup to its predecessor but benefits from improved software and image processing. It has a 12 MP wide sensor, an 8 MP telephoto sensor with 3x optical zoom, and a 12 MP ultrawide sensor. The S21 Ultra has a new HM3 108 MP sensor with several enhancements over the previous HM1 108 MP sensor, including 12-bit HDR. It also has two 10 MP telephoto sensors with 3x and 10x optical zoom and a 12 MP ultrawide sensor. [19] The front-facing camera uses a 10 MP sensor on the S21 and S21+, 32 MP sensor on the S21 FE, and a 40 MP sensor on the S21 Ultra. 4K@60 recording is supported on the ultrawide camera on the S21, S21+, and S21 FE and all cameras on the S21 Ultra. All cameras are Samsung except 12MP Ultra Wide on S21 Ultra and 10MP front on S21 and S21+, which are both made by Sony, and the 8MP Telephoto on the S21 FE which is made by SK Hynix.

Granted, we live in a different world now, and are probably close to a phone charger at all times, but that still doesn’t change the fact that it’s a mediocre battery performance from the Australian S21. Certainly not one belonging in 2021, with the workday battery life more like something out of 2019, and hardly two years later.

In photography, the Field of view (FoV) depends not only on the focal length of the lens but also on the sensor size. It is derived from the lens's angle of view and the sensor's crop factor. The lens's angle of view is a measure of the angle between the two farthest separated points within the frame measured diagonally. Simply put, this is how much of a scene in front of the camera will be captured by the camera's sensor. The S21 series consists of the base Galaxy S21 model, the plus Galaxy S21+ model, the camera-focused Galaxy S21 Ultra model, and the mid-range variant Galaxy S21 FE model. Key upgrades over the previous models, in addition to improved specifications, a display with a 120 Hz adaptive refresh rate, an improved camera system supporting 8K video recording (7680×4320) for the first three models, and a super-resolution zoom of 30–100x, for the ultra model.

Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor.

Usually cameras with larger sensors and less pixel density tend to provide better image quality despite the lower resolution. We’d say you can thank the 8GB RAM for how speedy the phone handles apps aplenty, though the odd slowdown definitely popped up when we were controlling the camera, which wasn’t always as instantaneous as we would have liked.
