Kavi's Sleepy Tablet

At bedtime Kavi noticed the tablet was still glowing bright on the shelf, and the charger was still plugged in long after the battery was full. "You look after me," Kavi hooted, "so I will look after you too." Kavi turned the brightness down, closed the apps that were still running, and switched the tablet off for the night. "A device that rests uses less energy — and a well-cared-for device lasts much longer." Looking after a device means keeping it clean and gentle AND turning things off so you don't waste energy.
