iphone 2am unauthorized data usage

Beginning on June 16, my original iphone began transmitting 2+MB of data "internet/MEdia Net" at 2 am every morning. Prior to this, my records show a daily data transmission at that time in the range of 8-50KB.

 

I changed to the 200MB plan when I upgraded to iphone 4 on June 24 and have begun monitoring data - that is how i discovered this escalation in data use. Both existing and new iphones are always on wi-fi at 2am. On 6/25, this 2am data usage jumped to 5MB, so I have switched off cell data altogether.

 

What is going on? At this rate, my iphone will use all 200MB of data in a month with these 2 am data uploads. I saw complaints about this on the Apple forum with no solution provided by ATT.

 

For 2 1/2 years, with my original iphone, I used an average of 30-50MB of data per month, so I was quite comfortable signing up for the 200MB plan. 

 

Is ATT going to fix this problem?

Also being told to put my phone in airplane mode, turn it off, etc. is infuriating. Why do I have to miss calls in order to avoid getting charged for data I don't want?

 


 

Why would you put the phone in airplane mode just to stop using cellular data?  That is just silly.

If you were on iPhone OS 3.x or older, I could understand it.

In iOS4.x, go to Settings > General > Network > Cellular Data and set it to OFF.

You can leave this off permanently, granted you will not be able to send/receive MMS messages or use Visual VoiceMail, but otherwise the phone works perfectly fine.

 

If/When you want to use cellular data, it is a very simple process to turn it back on.

I can't expand the memory (a fairly typical thing) or attach a photo to an email I started (Duh, Jobs!).

 

To fix many things requires downgrading and jailbreaking in a way that I cannot do on this phone anyhow.

 

 


 

There has never been any expectation that one could expand the memory of the iPhone, that's why it comes in two capacities and you select the one you are willing to pay for.

 

As for attaching a photo to an email, you certainly can do that by copying and pasting the pic into the email.

There are several data transfers including for overnight:

 * Voicemail

 * Push Notifications

 * Push Email (except GMail at times)

 * MS Exchange (Yahoo, MobileMe, and GMail support these)

 * MMS and SMS ping

 * active applications (7 API types on apps including Background API, file transfer to complete, etc)

 

You can close active applications by double tapping home, holding an active app, and then pressing the stop icon to close it. To prevent any data transfer, swap to airplane mode. You can also keep data going by hooking up a wifi router and keeping wifi enabled while on airplane mode.

It may be a program you've downloaded from the app store. But, I think the real question here is, if it's hooked to wifi, why is it using cell data? Mine does it too, but I still have unlimited data, so I'm not real concerned.

suspect that when the phone is in sleep mode the wifi is turned off, the cellular data network connection is required to be avtive even when the phone is off to be able to recieve phone calls, visual voicemail messages for the required. If it is an app, then the author needs to reevaluate how it sends and recieves data

I don't have any applications other than what came on the iphone. It is connected to WIFI. And the big problem is that this is "data sent", not data received! I would understand if this were data received, but it is not. And, why this massive increase starting on June 16. I thought it was the switch to iphone4 on June 24 until I looked at the data usage and found it started on June 16, the day after I ordered the new iphone.

it would be cellular if the wifi is in sleep mode and it appears it does not wake up the wifi connection for this.

 

It appears to be some form of update, maybe it is sending usage updates, not sure, have had a Iphone for a couple of years and the data records that I can check back to have always had the upload around 1am in the morning, prior to that the other smartphones that I have had did the same thing. I put it off to the fact I push check exchange, gmail and my isp provider email addresses every 30 minutes

I will check settings on my router to ensure that it is not sleeping. 

 

Regarding the 2 am uploads or 1am in your case, can you check and see if they increased exponentially in size on June 16? I am trying to get to the bottom of this - why they went from a few KB to several MB. 

 

If I do not manually turn off cell, I will exceed my 200MB data plan limit by the end of the month.

He was referring to wifi on the phone, not your router. If the phone is sleeping, it will use cell network rather than wifi, which answers my question. Thanks Wingrider! I didn't realize, or think about, the phone using cell data while in sleep mode.

Yes, I figured that out after looking at my router and it says that the iphone has been attached for 18 hours. I just changed autolock to "never" to see if this helps. 

 

I'm still looking for the reason that the data sent increased to several MB every night.

 

The other problem that I am consistently seeing is that my iphone will still rack up data even while it is attached to WIFI during the day. I'm assuming that this is because the phone is going to sleep.

 

But, even if that was going on before June 16, I never had the daily massive accumulation of data. My highest month was 50MB, but I was traveling and not connected to WIFI.

 

Has anyone from ATT chimed in here? I'm hoping that an ATT technical person can answer this question about the increase in data.

Not sure what "Wake on Wireless" means in Apple's definition. However WiFi can remain on if you are recharging your iPhone. I've recharged my iPhone nightly and the WiFi icon was always on after several hours.

 

However you need it on an active connection (wall plug) versus computer connection. If you have your computer going to sleep, it turns off the power transfer.

A few ways to stop/prevent phantom am usage accumulation:- turn off eMail Push & Fetch, close Safari windows, minimise the use of apps which utilize unattended data e.g. RSS Feed. Etc...

Thank you for the link to your thread on this topic.

 

Did you start seeing this problem recently or was it some time ago. For me, it started on June 16, which is the day I ordered my iphone4. I did not get the phone  until June 24. 

 

So, after 2 1/2 years on my first gen iphone, I had minimal data usage at night and now have this huge amount of data being transmitted - from my old iphone! 

 

This is beginning to smell more and more like an effort on ATT's part to ensure that you have to get a higher data limit. If the data increase had started on the day that I activated my iphone, I could blame it on Safari or push email, but it started before I got the new phone. And I certainly did not change my usage habits on June 16!

 

I don't think I should have to turn the darned thing off every night or any of the hardware solutions that I never needed before. I checked back records and my data usage was always around 30MB except the month I was on vacation when it went up to 50MB.

What is the dhcp release time on your router? Your router will hold it in the dhcp table until the device has been offline or out of ranged until the dhcp renewal time expires. In most routers this is a default of 24 hours so a device that has been issued a IP address from your router DHCP routine wil stay in the active list until the release time expires - as long as it has not reconnected back to the network, In the case of a wirelss device like the Iphone the default is for the wireless to auto connect to a known network/
