8849 (formerly Unihertz) touts its new Shark 3 as a "Lighter, Thinner, Faster" rugged smartphone despite its huge 10,000mAh+ battery. The device has an AMOLED display of modern specs such as a 1440p resolution and a 120Hz refresh rate. The Shark 3 also boasts dual 50MP rear cameras and faster charging than most flagships, although it also has its disadvantages.
