This App is actually related to a company that makes Money making apps.
This app does nothing but keeps running in the background and eats up your battery in turn decreasing your battery life.
Totally disapproves the name of the app itself Battery Saver
They just pop up ads and that too between your normal usage and the thing that annoys me the most is that, They ask for phone Usage permission and make themselves as an phone lock kinda thing when you unlock your phone.
Never download this app, really a waste of time!
