No. It only requires a minimal amount of power when you're changing the image. Once the image is updated, the smart ink screen holds the picture indefinitely without the need for a continuous power supply. This means that after you've set your desired image, the E-pic Case™ does not draw any power from your phone, preserving your battery life. The energy used to change the picture is minimal, ensuring that your phone's battery is primarily used for your phone's own functions, not the case. Enjoy endless customization with minimal impact on your device's battery life.
