Excessive data usage

[Kerstin]

I have switched to a O2 mifi contract with 95gb three months ago from EE with 60gb. I stream regularly (bbc iplayer, all4, amazon prime) and listen to internet radio. I just about managed with the 60gb, but since the switch I use up data much more quickly and use 60gb in about half a month. I don‘t know why this is happening. Is there a way how I can analyse which device is using how much data at which times? I have the suspicion that the o2 network has more bandwidth, therefore the streaming uses higher quality, but I can‘t find what app it is. Thank you!!

Go into the settings for each app and change the download from auto to lower quality streaming.

I have done that already where I could find an option (not for iplayer?). My question was if I can analyse the data usage in more detail anywhere. Thank you!

You can't from the mifi that I am aware of, hence my answer to help reduce data use, but if you stream to a tablet you can download apps that recorded data use so you can see where it's going.
