I am currently helping someone who has experienced large amounts of data being transferred over her DSL connection. After long research (via IRC support) I found out that her iPhone is obviously sending lots of data, i.e. several hundred kbyte/s, as soon as she connects it to her home network. The iPhone itself seems to work fine.

To find the culprit responsible for these huge amounts of data I would probably need to find a way to measure how much data all connected applications are sending within a specific interval.

As I do not use an Apple mobile device myself I am not familiar with iOS. Are there any possibilities to get information about the network usage of specific apps, either natively or with the help of a third-party application that is for free or at least offers a free trial version?

  • Please ask for this feature at Apple so they'll consider adding it. The more people that ask the more likely it will get added apple.com/feedback

You can do this with Onavo Count

Onavo Count monitors and analyzes all types of mobile data and phone use. This includes background, foreground, and Wi-Fi use.

iOS can do this natively under network usage. Just reset the stats with the bottom button and review later.

Go under Settings > Cellular and scroll down. You will see what each app installed on her device uses as far as data. (This is on iOS 7)

  • For previous versions, go Settings >> General >> Usage >> Cellular Usage

    This option is labelled "Mobile data" in the UK. It's not much use for apps that only use WiFi though :-(
