Helps prevent your phone from overheating in the sun and freezing in the cold while extending your battery life. Exceeds military drop-test standards (810G 516.6), protecting your device from drops up to six feet. PHOOZYÕs Anti-Sink, water-resistant technology acts as a life jacket for your phone, keeping it afloat if dropped into water. Disclaimer: The PHOOZY Thermal Capsule is not a phone cooler or phone heater, meaning it does not cool down a hot phone or warm up a cold phone. It helps prevent overheating in the sun by reflecting solar radiation (heat) and extends battery life in cold by insulating your device from frigid conditions. It is designed to increase the length of time your phone will maintain optimum operating temperature in both hot and cold conditions (compared to not using a PHOOZY Thermal Capsule), which can extend and preserve your battery life in extreme conditions.
