Recently I removed my unlimited data plan from my AT&T plan because I was only averaging about 6gb/month so I got a much cheaper plan allowing me 20gb/month thinking that I would not ever come close to that. In the last 10 days, since switching plans, I have somehow managed to rack up 15gb of data on my phone. I've never reaching this peak of data before in my life so I started to get a little confused. I decided to test out a few things so I used a Data Timer widget on my iPhone 6 to test out a few things. Spotify and Apple Music both are running about 8-10mb PER SONG when I'm streaming over my cellular network. On top of that even things like Maps/GPS is pulling in a ton of data. Researching it should really only be about 50mb or less per streaming hour and GPS should be astronomically smaller than that. The image attached to this is timing out 3 minutes of streaming on Apple Music (less than one song). All of the normal recommendations are turned off such as roaming is turned off, I do not use any push notifications or background refresh, Wi-Fi assist is off, etc. AT&T was absolutely no help and rather rude. Apple had me restore my phone, which hasn't fixed any of the problems I'm currently facing. Any suggestions? Is this abnormal? HELP?!?!
