    I noticed that my provider (Vodafone UK) was showing that I'd used 500MB of data since my last bill. I checked on my iPhone on the cell data counter and it was only showing 250MB.

    Thinking it was odd and either the iphone or provider was wrong I set about some testing.

    I ran some speed test which I knew would use a few MB and so should increment the counter. It did.. A few more tests and I can see the counter is now at 300MB. So initially I thought it must be working and some-how, after a few years, Vodafone UK are suddenly grossly over counting my data (unlikely) or maybe some of the background traffic the iphone makes (diagnostic data, Siri etc) wasn't part of the usage counter - which would be odd.

    I've now discovered that after resetting my phone the Cell Usage counter is back down to 250MB! Is this a bug? It looks like maybe the number isnt been stored correctly and is somehow in volatile memory and the phone reset caused the counter to go back to the last committed value?

    Any-one else able to test / verify my findings?

    Could be a few people with surprise bills if they are using more data than their phone is reporting. Especially with all the reset advise floating around to help battery usage.

    I wonder if its accidentally including wifi data usage?

    That would mean that Vodafone is counting Wifi - which would only be possible if the data was actually going over 3G and not Wifi.

    The test I did earlier was without Wifi at work. So the increase in Cell Usage I saw on the iphone counter prior to the reset was the result of actual Cell Data.

    That's really weird as my data is spot, fair enough I do use wifi alot but my data allowance is fine, have you spoken too Vodafone as they will be able to see if any unusual large amounts of data is been sent from your phone.
