    Since September, when this issue affected me, I have consistently switched off 3G, Mobile Data and Data Roaming when I'm at home. I only turn them on when I leave the house, and only if I know I'm going to need them.

    I've downloaded Onavo and Dataman, which I monitor my usage, and overnight I leave it on charge so that it doesn't revert to 3G even if it is on, it stays in WiFi.

    I also turn off ANY apps which use Data when they are not in use.

    Looking at Dataman, the WiFi is using quite a lot of data in the night, anything from 12.3kb to 4.9Mb but as this is in WiFi it doesn't come off my Data allowance.

    I agree with purpleberry, and general usage. So far this month (started 27th March) Dataman shows I've used 25.7Mb on 3G and 362.6Mb on WiFi

    The hungriest App in terms of Data is the Maps function which eats into the allowance more than any other as far as I can see. I used almost 10Mb of data pinpointing a premises using it.

    The only way to stop this problem is to keep 3G switched off and plug the phone into a charger overnight to keep the WiFi active for downloads.

    Hmm, - since my post, I called Apple and they've told me it must be down to 3rd party apps, because if it was as I - and O2 - claim, everybody would have the issue, and not just the few posting on here. Fair point.

     

    My girlfriend leaves the phone on charge overnight most nights, and the wi-fi is always on. Something on my girlfriend's phone is going onto 3G at midnight (00:00) every night. Most of the time it is around 20Mb - however there has been a 100+Mb in Feb, and 445Mb (this is not a typo - it is half a Gb !)  in March ! A few 60Mb's etc also dotted around. All have the mysterious 00:00 time.

     

    So following Apple's reasoning, and your helpful comments I concur it must be an app (or apps) doing this. I will check this by a process of elimination shortly and report back, but...given its a common problem, and you have to go through the fiddly process of swtiching off of things, etc - you'd probably agree with me it would be helpful if they had a seemingly simple option "updates only on wi-fi / wired connection." ?

    The 00:00 time is just when O2 update your data use for that day. iPhones use a lot of data and personally 500mb is not enough for a month, I think that O2 do over calculate as I've changed to 3 network with 500mb (use wifi most of time) an have never went over, I've received an email for unlimited data for £3 extra a month. How much is 1gb on O2?

    If you think it's apps a lot of free ones call home and display adverts which use MB's. Also stop apps running in background, download apps in settings to wifi only. Check email accounts turn of push and check when they update same as weather and stocks.

    The data transfer at midnight is a red herring. That is not the time the transfer occurs, it is the time accumulated data over the course of the day is posted to the billing system. You need a monitoring app such as Dataman to determine when the data transfer actually happened.

    Unfortunately 3 doesn't do coverage as well as O2 (where I am at least) - and seem to try to make up for it with the best deals. Good point re adverts on free apps - however I don't think they account for 445Mb at 00:00 hrs ! Push is always off. Switching off apps in background is a bit of a hassle - I think best way is first of all to determine the offending apps, and secondly keeping 3G off until it prompts you to use it when an app asks.

    You guys sound as if you're being taken for a ride! I am still on pay-as-you-go with O2 on iPhone and have none of these problems! I think 'scam' sums it up! You have my sympathy!

    Ive now downloaded dataman, Ive found it very interesting and I would reccomend this to everyone having this dataleak problem.

    Im working nights this week, Ive been keeping an eye on it all night and monitoring my usage.  My 02:00 usage showed 48.3mb in 1 hour, the only app I had open was the 02 app to check your allowances and it had only been open for 5 minutes!

     

    After going through some other forums Im switching off iCloud, that seems to have solved a lot of issues.

    I got the O2 text this weekend stating I'd used 80% of my data allowance, been with O2 for a few years and never had this before. I popped into the O2 shop today at lunchtime and I got a top tip from one of the O2 guru's.

     

    with ISO5 there are settings which state

     

    "You can help apple improve its products and services by automatically sending daily diagnostic and usage data"

     

    This was set to automatically send. Ive reset it and fingers crossed this will solve the problem. To reset do the following

     

    Settings

    General

    About

    Diagnostics & Usage

     

    TICK DONT SEND

    Hi, this is my first post so all you experienced people out there please be kind. I too had a problem after to switching to an iPhone 4s from Blackberry a few weeks ago and I have NEVER exceeded my 500Mb limit. I was averaging 150-200Mb per month and that was using constantly using FB and sending emails etc constantly. Yesterday, I was shocked to find out I had exceeded my 500Mb limit within 10 days, however O2 did give me another 500Mb free to last me til the end of the month as I am normally under but frustratingly they could not explain what was wrong.

    I waited til I got home to my wifi connection last night and turned off my 'Mobile Data' (Settings/General/Network) then ensuring you ONLY use wifi even if your phone goes into standby or what have you. Anyway, I then downloaded the app Data Usage Monitor (its free) and then tracked my usage on Wifi for the evening, doing exactly as I had been doing on my 3G. heres what I found.

    I played 'Words With Friends' and 'Draw Something' for approx 30-40mins and used 10.5Mb. I then closed them both, reopened WWF and had one go and closed it again and found that it consumed 1.5Mb of data. So I do not know where people that say these apps use minimal amounts of data get their information from.

    After this, I turned the Mobile Data back on, went for a run to see just how much data RunKeeper uses as its GPS based. 30 mins running used 1Kb. Nothing whatsoever! Then I turned the Mobile Data back off.

    Last night in total I used approx 65Mb of data (on wifi) so I can see why I used my 500Mb in a matter of 10 days.

    Today (since 8.30am when I switched the Mobile Data back on) I have been on FB two or three times, posted once or twice, sent a few imessages and pulled through a few emails BUT I  have NOT touched WWF or DS and I have only used 3Mb as of 12.40pm. Whereas yesterday by this time I had used something in the region of 30Mb

    So (for me anyway) the route of the problem is these two apps, where people have said they use minimal amounts of data but in actual fact use large amounts. (Oh and sync through itunes and turn icloud off)

    If I am wrong and there is a way to use these apps and save data another way I would be happy to listen as Im only a newbie when it comes to the iphone.

    Hope this helps??

    Just keep doing what your doing, play them games on wifi. All I can say is 500mb is not enough for iPhone a month. People on pay n go should look at GifGaf or unlimited Internet tariffs.

  • mentalasanything Level 1 Level 1 (0 points)

    Thanks Lawrence. Got dataman now. Looks good - it'd be handier if it went one step further and attributed data usage to the specific app.

     

    If you open up the hour's usage the mysterious non-iconed data user "DMTT" comes up frequently (but not every hour). Can anybody tell me what "DMTT" stands for ? I Googled it but as far as I can recall I have never communicated with Des Moines Table Tennis club, or The Durham Model Trucks and Tanks club ;-)

    I have also downloaded Onavo, which is much more specific about which app is using data. Ive only been on wifi since downloading so not sure how good it is yet but sould find out later today.

    None of the steps taken by me so far redcuced my data.

    I switched off icloud, ni improvement

    I deleted icloud and saw an almost instant improvment for about 3 weeks

     

    Then about 3 weeks ago I use 250mb data in 3 hours? I had recieved 3 small emails, sent 2 tweets via echofon and looked at staus updates once on FB between the hours of 6am and 9am and this took up 250mb?????

     

    Since then Ive had another few spikes of 90mb+

     

    I have no idea what is causing this problem. I think I will update now to 5.1.1 and see if I get an improvent, if not I wil be calling o2 and asking for a goodwill tariff change, if they dont let me change to unlimited data (which has just been reintroduced for NEW customers) I will be leaving them and taking 2 iphone, 1 pad, broadband and home phone account, which in total is about £150 per month not including my data roaming for which they also make a packet!!
