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 xe2x80x93 WIRELESS & NETWORKS
