Hi,
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.
Thanks,
Steve
