Samsung Galaxy S21 5G

The powerful and impressive Samsung Galaxy S21 5G is ready to tackle any job, thanks to its capable array of hardware internals. While its slim design and 6.2-inch dynamic AMOLED display are easy on the eyes, the smartphone’s real power lies in everything under the hood. The phone sports an octa-core processor (either based on the Exynos 2100 or Qualcomm Snapdragon 888 chipsets, depending on where you’re located), a 4,000mAh battery that supports reverse/wireless charging, 8GB of RAM, and up to 256GB of internal storage. The Android 11 phone charges via USB-C, support dual-band Wi-Fi, Bluetooth 5.0, and 5G LTE cellular connectivity. But perhaps the phone’s great asset is its quad camera array, which is capable of recording video in 8K. The 12MP wide, 64MP telephoto, and 12MP ultrawide lenses can easily capture important moments and details. A true powerhouse that’ll be a great addition to any workplace setup.
