Thankfully, this app is here to optimize how much of your battery is consumed by extraneous apps running in the background. Now you'll be in the know at all times when it comes to exactly which apps are using more resources and you'll be able to close the ones you don't need -- saving you a precious few more minutes of battery life. From the menu in Power Plus, you'll find out exactly how many minutes are added to your battery life when you close the apps it suggests.
Also the option to see how long you have until your battery completely runs out is easily available at all times so you'll know when your device shuts off and the exact charge percentage you have left, as well as manage charge times to get the most out of it.
Lastly, from Power Plus, you can also access a summary of the use of all your apps, letting you see exactly which apps are using more battery and then proceed to close them directly.
