Same problem here.

 

Is there an app that can detail WHAT proc/service is using how much data?
That might come in handy for those that don't have unlimited.

If not, that's something that's needed.

I use 3GWatchdog just to keep tabs, but it just sums up total xfer/rcv.

Turning your wifi sleep mode to never and turning off background data should help tremendously. My daughters first night with her phone she used 94 meg at 3:00 AM while she was sleeping. After doing what you did above she has only used 2 meg in the last week. I also have installed advanced task killer and have it set to kill most tasks when the screen goes to sleep.

 

But seriously, WTF is using 94MB @ 3:00am to BEGIN with?
Has AT&T put in some DataSuck Triggers or something?

I can't even BEGIN to imagine what uses 94MB @ 3:00am. That's a crapload of email/fb updates!!!

I agree and I called AT&T to ask them if they could shed some light and the person I spoke with had no clue and could not find anyone to help me and told me someone would call me back within 24 hours. That was 2 weeks ago.

She had not even set up her e-mail or downloaded the facebook app at that time... It was the first night she had gotten her phone and she hadn't downloaded many apps at all.

 

That's just BS...

I used Pandora last night for like an hour, and it was only about 40-50MB! Can't imagine 94MB! Especially @ 3AM, when phone owner is asleep.

That looks REALLY fishy...

I have no idea how this is happening to you. I haven't noticed any such random data usage. Maybe it's the applications you've installed?

 

i have the 200mb plan also, had the phone since the 18th and i havent even used 50 mb. mine is always connected to wifi for the most part, i have a few widgets that auto update. you may want to try 3g watchdog as it tells you how much data youve used, not 100% accurate but you get an idea. also you can try juice defender, its supposed to save you battery but it shuts down the 3g while the phone is asleep if you have it set to do so, i believe you can even turn the data all the way off but not to sure on that one

 

There has to be something wrong with your phone. Some people couldn't use that much data if they tried to. There has to be a way to find out what is using all that data.

 

Yea dude something is wrong with that. That's a crapload of data in just one day unless it's streaming video or music or freaking moving the international space station into posistion...I've had my phone since the day it's come out and used approx. 500mb and I'm never on wifi even though I could be.

 

In the last 5 days I've used 154mb, and I'm on Twitter and Facebook A LOT, all over 3g. I can't imagine what could possibly be using up all of yours while you're sleeping, but it can't be good. Hope you get it figured out.

 

Yeah - what THEY said...

That's like 80MB/hour average!

You could run Pandora for like 10 hours and not suck that much down.

DEFINITELY call into AT&T and see wtf is going on - that ain't right, and you're going to get stiffed with a nasty bill.

I'm pretty sure thats when at&t bills you for the previous days data usage.

 

I'm having this same problem too. Lots of unexplained data usage when the phone was almost certainly on Wi-Fi. When I called AT&T they said I must not have "logged off the Internet properly".

Coincidentally we just moved from an Unlimited data plan to the 200 MB/month plan. Since moving off of the iPhone Unlimited data plan, AT&T is measuring about 5x the average bandwidth used over the previous 6 months.

 

How do you turn off background data? I can't find that in the settings.

 

Wow, sounds pretty scary. But I won't lie, I'm worried too. My Captivate pretty much sucks my data like crazy. Thank God I was grandfathered into the unlimited iPhone data plan. But I have a gigabyte already racked up!

 

Maybe the data usage is something like this? Those Nighttime iPhone Downloads Are Actually Not Downloads

 

This happened to me as well. My phone used 1.6GB within 5 hours while I was sleeping on the first night I had it! I had AT&T business on the phone the next business day but they couldn't explain it. They bumped me up to the 2gb plan and will reimburse me for the cost.

I have been using 3g watchdog since and it hasn't happened again.

 

Settings - Accounts and Snyc - Uncheck Background Data

 

question from a newb, how can you tell how much data is moving and when? on the phone or an app?

 

Use a widget like 3G Watchdog from the market.
Once installed, go to the dialer, dial *DATA# and press <send> and it'll send you a text with data used so far.

Install the widget (long-press on the desktop, select widget, select 3G watchdog)

Go into the 3G Watchdog setting, set the date to the date your month starts, go to quota and set it to the data amount you got in the text from AT&T, and then save the settings. You can change the update interval, as well, and the widget on the desktop will show cumulative usage.
