Engineers from California's UC Berkley have created a program that detects applications that gorge unnecessarily on a device's battery and lets users shut them down or update them.
Adam Oliner and his team unveiled Carat this week, promising their program will improve the battery life of phones, tablets and portable music players.
Since being released, more than 36,000 Android and Apple users have downloaded the app that quietly works in the background of devices, using little to no energy to work its magic.
