How do I check which apps are using wifi?

Question

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?

Answer 1

For even more detail, I recommend Trepn Profiler from the Play store. It's developed by Qualcomm and analyses CPU usage, Wifi and cellular data usage, and more.

Answer 2

Go to: Settings > Data usage – WIRELESS & NETWORKS

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