    Does anyone know what the data rate per hour (MB or GB / hour) for streaming iTunes Radio over a cellular signal on an iPhone 5 via Verizon Wireless?

    I'd rather know off hand than killing my plan. I'm trying to adjust the monthly usage.

    Thanks!

    On cellular iTunes Radio uses approximately 28MB an hour.

    I am guessing iTunes Radio usages 128 bitrate. So, extropulate 128000 x 60 = 7.6 megabytes per hour. Each hour you stream equals about 7.6 megabytes.

    I use spotify and you can specify different streaming qualities. Of course the higher bitrates use more bits and bytes.

    That seems awfully low.

    Forgive if I'm wrong, but wouldn't the math work like this:

    1MB = 8000 kb

    (128kb/s)*(60s/min)*(60min/hour)*(1MB/8000kb) ~= 57.6 MB /hour

    80kb/s ~= 36 MB / hour
    256kb/s ~= 115.2 MB / hour
    320kb/s ~= 144 MB/ hour

    Streaming Audio Rate: 36MB/Hour < Actual Usage < 144 MB/hour


    Note:This assumes that there isn't any other data that hitchhikes with the audio when ones uses a streaming audio service

    Does Apple gimp the signal on US carrier signals as much as it apparently does on Australian carriers signals?

    Lowering the bit rate by a significant degree seems to be the only way to obtain the ~30MB / hour target. In fact, when I use my previous calculation, the the bit rate for iTunes radio would need hover slightly south of 65kb/s to maintain the ~30MB/ hour target.

    I tested iTunes radio out on cellular and it wasn't bad. I had it playing for 2hrs and where I was the signal fluctuates between 3G and LTE. 5-10MB used. I find it works better than GooglePlay. For some reason that app buffers too many times.

    There is no way that's possible.
    iTunes Radio uses about 30-40 MB an hour for me on my iPhone 5c on LTE.

    That sounds more reasonable, but it would still indicate that a relatively low bit-rate signal (~80kb/s) on iTunes Radio via a cellular data signal.

    Do you have any approximate rates for other audio streaming services?

    Does anyone know the bit-rate for the Sirius-XM app?

    Good question. I couldn't find the answer.

    SiriusXM uses about 1 MB per hour or 60 MB per hour.

    I have to check again to get a better accuracy. But I'm sure that's what I saw. If it starts to buffer then its possible. If I don't get a signal then it's possible. So that would make my results different from yours. #anythingispossible
