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?
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.
Go to: Settings > Data usage – WIRELESS & 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.
