How do I check which apps are using wifi? I'm using the red mi 2 and data transfer is taking place via wifi, problem is I don't know which app is using it. Is there a way to see wifi usage statistics?
Go to: Settings > Data usage – WIRELESS &amp; NETWORKS


Tap the right-top menu. It will open up a popup menu.
Check *Show Wi-Fi usage.
Go to Data Usage. You'll realize a new tab called WIFI is added nexto to MOBILE.
There, you can see all apps that use WIFI and how much data they use.
