Many iPhone users are noticing a fast drain in battery life in iOS 11. You can check which apps are using your battery by going to Settings –> Battery and then scrolling down to where it says ‘BATTERY USAGE.’ You will see a screen like this:

This is a very handy chart that lets you see which apps are using your battery. For me, it’s Google Play Music. I admit, I do use the Google Play Music App a lot to listen to music.

If you click on the App in question, it will tell you how much you have used it. I clicked on Google Play Music and it told me that I have used it for 2.3 hours on the screen and 4 minutes in the background over the last 24 hours.

Click on the app name to see whether the usage is when the app is on screen or in the background.

You can look at your battery drain over the past 24 hours, or the past 7 days.
