Android users are familiar with excess battery drainage on their devices. Most of the time this has to do with the cores of the device consuming battery life, even when it is idle. Owners of the Sprint Galaxy S3 SPH-L710 are in luck thanks to XDA Developers’ member eugene373. He has developed a mod that puts the cores of the CPU to sleep when they’re not functioning. It’s called the CPU Sleeper.
The mod works on all quad-core and dual-core devices. When the screen of the device turns off, the mod puts the 3 CPUs offline, and leaves only 1 running. When the device is held and the screen turns on again, the three CPUs come back online. It’s a simple hack that will be very handy for all android users.
