After scanning your PC, this program will detect how much energy you can save by removing unnecessary and energy-consuming applications, and can also resolve any problems that cause low battery productivity.
Battery Optimizer will give you an exact figure of how much battery life you can save by closing every application. It can then save those settings as a profile type so you don't always have to close the same tools over and over again, and instead just choose your custom mode.
If you want to add a few minutes to your battery life, this is the program for you, especially for emergencies when you don't have your charger on hand. It will also always show how much battery life you have left.
