DU Battery Saver

Many Android users want to know how to improve their battery and, most of the time, it all boils down to application that continue to work in the background, even though they probably shouldn’t.
 
Applications such as DU Battery Saver are really good at finding the apps that don’t belong, leaving the option of closing them to the user. People can choose a number of presets modes for various scenarios, and there is even a cool down feature that works by systematically monitoring, managing, and disabling CPU-intensive apps.
 
The application also provides a warning about apps that use too much power to perform their tasks, comes with a widget for quick information, and it also shows the display charge status in real time, accurately estimating remaining charge time.
