Hello,
I just noticed on my carrier's app that my usage was way up for the usual in me. It's been 3 days since the last reset and I have already consumed around 512Mb of the 4Gb I have available. In a normal month I usually use maybe 1Gb or 2 *at most*, so in 3 days having used 512Mb is just a lot.
So, I went to see the Cellular data page on te Settings app, and no app is using anything to be worried about. The culprit is inside System Services, and it is DNS services.
This doesn't make sense at all to me. I'm usually on a WiFi network, and for what the carrier's App say, the big jump was today: it says that I have used 472Mb today, versus 12-15Mb the days before. Today I have been maybe for 80 minutes without WiFi (the car to the office, and later walking the dog) and I only hear music on that times, very seldom use anything else by myself.
So, what could be the reason for a spike on DNS services today? Is there a way to track the app that made the original requests? I have checked the battery usage to see if there is some app that has used too much battery (I mean, 450Mb of DNS requests are *a lot* of requests!) but I can't see anything strange, everything feels normal: WhatsApp on background, Music on background, FB on background.
Does anybody knows if the DNS requests always go on the cellular network? I believe that the notifications always use the cellular network, but I wonder if the DNS too? In any case, I don't recall doing anything out of the ordinary today to justify so much requests.
I am worried because I'm going on a trip on a few weeks and definitely need to have my cellular data available...
It is an iPhone 6s with iOS 10.0.1 (was on the developer betas, but since the GM came out I installed it, so I have been on this version for a week or so)
