App to view power hungry apps

[PhantumNZ]

Using mainly Samsung Galaxy S7 phone and I have power hungry apps.
Is there an app to view which ones are power hungry?

In battery settings you can get a list of apps that consume battery in the background and foreground.

If you want to know which app drains battery while you are using it, then you can use AccuBattery...
