My internet connection is 256kbps. From my PC, my download speed is 32k/sec. So let's say I'm downloading a file from my PC. I see the download speed in steady 32k. When I connect my iPhone to the Wi-Fi, the download speed goes down to 20k or less. I see using some Data Usage apps that the iPhone is receiving a lot of data. That means my iPhone is using +12k to send and receive data (mostly to receive) over the Wi-Fi (it doesn't happen when I'm using Cellular). In my iPhone, I closed all open apps, turned off Cellular Data (I dont want to use it), In Fetch New Data Push is Off, and Fetch is set in Manually. How can I know what Data and/or app is sending / receiving? Is there anything I can do not to receive too much data? I only want to send / receive data from open apps. Thanks!
