Sleeping iPhones Send Phantom Data
Stoobalou writes with a story that got started earlier this month when iPhone users in the US and the UK noticed that their phones seemed to be sending large data bursts via 3G overnight. (Providers are ending unlimited contracts, so iPhone users are paying more attention to how much data they are using.) The discussions began on MacOSRumors and an Apple discussion forum. Thinq.co.uk makes this guess as to what is going on, but doesn't offer much in the way of substantiation: "The simple fact of the matter is — as far as we can tell — that the iPhone's push notifications and other small transfers of data are totted up throughout the day and the total for all of those notifications is added up after dark and sent to your airtime provider while your phone is sleeping. If these tiny amounts of data were individually listed your bill would probably be the size of a telephone directory. The reason it is using the 3G network rather than Wi-Fi is that all iPhones up to and including the 3Gs turn off Wi-Fi push functionality while the phone is in sleep mode, in order to preserve battery life. The iPhone 4, incidentally, has better power management so will not need to do this."
iPhones are dreaming!
Do iPhones dream of non-walled Androids?

Combine this news with the timing of the AT&T 2GB cap announcement with the release of iPhone 4, and well, it smells like a forced upgrade.

The headline is contradicted in the summary. It should read: Sleeping iPhones Appear To Send Phantom Data.
Turns out they don’t, it’s just a total of use from the entire day that accumulated a lot of tiny data transfers made by the iPhone’s system which are too numerous and trivial to itemize on the bill.
Alexander Peter Kristopeit bought his basement from his mommy for one dollar.
The iPad (even non-3G) and the Touch also have the ability to stay logged into a WiFi network in very low power mode and so can get push data over WiFi. And I can't imagine these were forced by AT&T.
Besides, what if you are in an AT&T dead zone (of course we all know these are mythical ;) and you get a FaceTime(TM) call or try to Find My iPhone? Wouldn't you like it to get through on WiFi even though you can't get a push over 3G to your phone?

According to the article it's not sending data in the middle of the night. It just appears that way on the phone bill because they add up all the push notifications for the day and list them as one transaction.
Asking such questions is silly. It will only make things harder. Just accept the word of Father Steve and relax. You'll find things are much nicer when you accept this. I did, and I'm happy all the time now.

We have about 150 iPhones for corporate use and we have had to return 8 so far because of bad battery life. We have had more reports of deteriorating battery life from approx. 25 more users that doing a full restore to the phone and NOT applying the backup, just rebuilding the phone manually, has resolved their battery life back to original capacity.
The key is not to restore the backup created immediately before the restore in iTunes. Even though all of the push and antenna settings are set correctly, there is still something in the OS that makes the battery drain.
The worst one I've seen so far would drain 8% every 5 minutes; you could literally watch the battery percentage count down like a timer. Doing a restore of the OS fixed it.
You got modded down for the Foxconn bit sparky.
Foxconn build stuff for HP, Cisco, Nintendo, and I think Microsoft.
That comment was clearly a troll and unbalanced. So yea it was both a flamebait and a troll.
Get over the persecution complex.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
I understand your qualms, but, I just don't share them.
Yes, Apple maintains control over the app store. But, generally it's intended (at least, in theory) to ensure that the user doesn't have a crappy experience. I have a new iPad, and from just the free apps that are available for download, it largely does everything I need it to do.
Heck, I seem to recall seeing an app which basically a stripped down browser that operated in safe mode, and chucked all of the data when it was done. So you had "private" browsing such as it is. One could surf porn using that if they so chose, but Apple doesn't want to sell or be associated with porn.
However, I'd point out that only just last week or so, Microsoft said they'd not be allowing porn on the Windows Mobile devices, so it's not like Apple is doing anything different there. I'm betting that under most circumstances, most fortune 500 companies don't want to be associated with porn.
As to the products ... between using my iPods (I have four accumulated over a decade), my iPad, and iTunes, I've come to appreciate the very integrated experience, it "just goes" -- your mileage may vary, but people using Apple products are actually kind of happy for the rubber-bumpers and safety rails. I'm acutely aware of the fact that they've covered up the sharp edges and made sure to put safeties in all of the outlets. But, I really enjoy it for that fact, and, IMO, it actually contributes to the overall experience. If I want to operate with complete freedom, I have Linux, FreeBSD, XP, and Vista boxes I'm free to do anything on I want.
As far as the whole carrier thing, I would go so far as to say that every cell phone I've ever owned has been tied to the carrier who sold it to me, and the exclusive deal Apple originally did with AT&T kept that business model going. I also understand they're going to start selling unlocked iPhones, so one could be unchained and not need to jailbreak.
I guess if you think your freedom is being restricted, their products aren't for you. If you actually feel like they've just set you up with good choices that work and do what you need, you don't see it that way. And, it's apparently a completely binary position from what I've seen lately on Slashdot. It doesn't seem to be possible for their to be a middle ground.
To me, I like their products because they strip out all of the fiddly bits and focus on what it is you want to do with them. Having my iPad controlled by my existing iTunes actually simplified things for me. Far more so than a netbook, which I think would both require more care and feeding, and still be beholden to the keyboard and mouse model. Checking my email in my backyard while playing iTunes and then going back to my e-book ... well, that alone was worth the price of admission. Same goes for taking some documents I need to review away from my desk, and sitting in a comfy chair. I'd rather review a whole slew of technical stuff not sitting bolt upright in a chair, and not with a laptop sitting in my lap. This is more like a hardcopy.
And, really, for defending Apple, recent stuff shows me I'm more likely to get modded down than you are. On a lot of threads is seems mindless Apple bashing gets modded up, and actually trying to discuss the issue and defend Apple gets one modded as Troll. Because everyone has some pet crusade that, for them, makes any and all Appler products completely EVIL ... and people seem unwilling to acknowledge the point that their point of view doesn't match that of the people who actually choose to use, and enjoy, Apple's stuff.
Cheers

That seems odd though, because you'd think such behaviour would have to be carrier-specific. I.e. AT&Ts systems would have to know to expect such updates from the iPhone and rely on the iPhone to monitor its usage.
But the iPhone in other countries is sold completely unlocked and you can whack any SIM card in it and use it on any network. The network doesn't know that you're connecting from an iPhone or any other 3G/HSDPA device. So the network wouldn't know to listen for these iPhone data updates (and would be keeping track of data usage on the network side like it would for any other device).
I don't own an iPhone, so this may be something completely obvious. But it sounds to me like the US iPhone software/firmware is different from the software run on non-US devices (i.e. there's a "AT&T-locked" version for the US which contains this data reporting feature, and a 'regular' version which does not, for use internationally)
Depends if you think of the phone as a 'portable personal computing device', or really just 'an appliance'.
Like you, I couldn't stand anyone telling me what software I could or could not run on my personal computer (running Linux or Windows or whatever). It's a ~personal~ microcomputer which I should be able to make run any arbitrary code I desire to feed into it. I can even write my own software for it.
Some might also consider a phone to be the same - a completely open bit of personal hardware that they should be allowed to do with as they please.
OTOH I think a lot of people out there (not saying I'm one of them) consider a phone as merely an appliance. They buy it in the knowledge that its not an 'open' device you can do what you want with. But they don't care. I mean ... they don't really care that I can't run arbitrary code on their DVD player or their microwave or their car stereo system or whatever. And they think of a phone as being in the same class of device - they just want it to work and don't have a desire to do anything more fancy with it.
Apple has been successful selling such locked down products to that kind of consumer. You (and I) disagree with that approach, but there are good alternatives out there, so there's no real reason to get worked up about it. If I don't like it, I won't buy it.
The 'locked to a carrier' thing is also strictly a US thing. In my country (and most others) you can just whack any old SIM card in an iPhone and it will work on any network like any other phone. I should also point out that Apple's actual ~computers~ (i.e. Mac OS X running laptops and desktops) are still open platform 'personal computers' ... indeed these days you can even run Windows or Linux on them). So I don't think the lock-ins pervade every product they sell. Just the iPad/iPhone/iPod/etc.
But you're right - you shouldn't be modded as troll for discussing these things. They are legitimate concerns with Apple's products. But I just think that you are not Apple's target market - you want a computer when they are really just trying to sell an appliance.
This is true. And it's actually a battery saving technique. The phone will attempt to transmit and make a connection with the weakest possible transmission power possible. If that fails, then it kicks up the power and tries again.
In the well covered areas, it doesn't take a lot of power to hit a cell phone tower. So the amount of power needed to stay in contact is minimal. In a weak signal area, it takes more power to maintain that contact, which is why the battery drains faster. Also, in weak signal areas, the signal tends to be lost completely often. When that happens, the phone will wake up and start searching for a new tower using the previously described ramp-up method. It will keep attempting that every minute or so until it finds a tower.
