After completing the installation process, I opened the app by going to my phone’s Main Menu → Applications → Best BatterySaver which further guided me to its main menu where I could activate or deactivate the application.

I could easily initiate and configure automatic profile switching by clicking on the ‘Schedule’ tab. The ‘Charger Rules’ option allows you to define profiles when the device is connected to AC mains through a charger or when it is disconnected from a charger.
The application also has several pre-installed profiles and I could activate any configured profile manually or simply activated the automatic profile switching mode to automatically load a specific profile according to my schedule or various situations. These profiles are highly customizable with a lot of options and can be configured in any way you want.
For example, I could configure a profile that automatically changed the screen brightness from low to high when I connected my device to AC mains for charging. I could also configure a profile to switch off the Bluetooth on my device when the battery status was low. An auto-restart option is also available that automatically initializes the app when you restart your phone.
