Drains battery and data

App drains my iPhone 6 battery, even when not active. When not even in use, it uses data at an alarming rate. I have exceeded my quota two months in a row even though the app wasn’t running. As soon as I remove the app altogether, my battery usage improved and don’t use my data. This is a wasteful app.
