Looking on MR, I found similar threads mentioning issues with Usage statistics on the 4S, and Battery issues. But I thought I'd compile the two very well known issues that affect the minority of the 4S owners: Usage and Battery I got the 4S very recently, and I've realized that I don't have the battery issue, but I do have the Usage issue. My 2 day old AT&T 4S went from 0MB downloaded/uploaded on the first hour, to 540MB downloaded and 85MB uploaded on the 3rd day. Thankfully, I have the unlimited data plan, so I'm not really worried. But what worries me is that when I dialed the *3282# to get my usage info from AT&T, it only said I had used 98MB on my new iPhone. (Right before I got the 4S I had dialed that on my previous iPhone to see the usage, and then I just dialed it now, to calculate the difference). So the question remains, did my 4S use 400MB, or was that some phantom data? Now, before you all say anything, I realize that AT&T's system is slow and takes time to update usage statistics. But, my question is this: even if the system takes 2 full days to slowly update your usage statistics, did my 4S then, really use 400MB in just 2 days? I haven't done anything out of the ordinary from my previous iPhone, apart from playing with Siri a bit. In my previous iPhone, I managed about 80 to 100MB a day max. So this 250MB or so per day is really pushing it over the top. I can't see Siri using 250MB of data for the <50 times I have pulled up Siri. So I'm not sure if the Usage Stats issue is a software glitch, or if the 4S really is a data hungry iPhone, but going from the small but persistent number of people verbalizing about Battery and Usage issues, I'd say it's definitely real and persistent.
