Deadhead,
Here is what I tried from another thread....
This iOS 6 Setup Guide was posted in this forum way back in October.
It may seem a bit tedious, but beleive me, it does work...
iOS 6 introduced a number of "enhancement" which enabled you to "configure" what you want to stay in touch with instantly, and how you want your Apps to behave.
My recommendation: work thru the list, it will provide you with some insight into what you have setup to allow stuff to go on in the background
And: get into the habit of shutting down Apps when you have finshed with them...
Double click the Home button, this will show you all the Apps running in the background.
Tap and hold on one of the Apps, then tap each one of the shaking App buttons to shut it down.
[But you know this already, just do it as a routine for a while, and see what happens]
Enjoy...
PS: am just a User of iPhone, just lke you...
And had an issue with Cellular Data Usage, like so many others who visited this forum when they first fired up iOS 6 on their new iPhone 5, or existing 4S, and 4...
Most are now happy, issue resolved, and gone from this forum.
iOS 6: Setup to Optimise Cellular Data Usage…
Many of the iPhone 5 iOS default network Settings are intended to create best user experience and performance, by utilising available WiFi and high speed LTE and/or 4G Cellular Data networks.
If your cellular data plan is limited, less than a One GB per month, it would be wise to work through the defaults, and turn off those services that are not important to you.
Here is a guide, courtesy David and Olli, contributors to the Apple Support Community...
Network Reset: reset the network connection…
Make sure you know [or have saved] your various wifi passwords so you can quickly set them up again.
Settings, General, Reset, Reset Network Settings.
Cellular Data: turn it Off when you don't need it…
This may sound messy, but it is really no more so than turning off WiFi, or Bluetooth, when you know you will not be using it. Maybe Apple will move this setting to the front page of Settings, as they have done with Bluetooth in iOS 6
Settings, General, Cellular, Cellular Data, Off.
iCloud Backup: Turn it Off except when you need to do a Backup to iCloud…
Otherwise iPhone will automatically do a Backup over WiFi and/or Cellular Network, while it is on Power, and sleeping.
Settings, iCloud, Storage and Backup, iCloud Backup, Off.
iCloud Documents & Data: turn off the use of the Cellular Data connection, until you need it…
Settings, iCloud, Documents & Data, Use Cellular Data, Off.
Location Services: make sure only the apps you consider critical are switched on…
These are new Settings in iOS 6.
Settings, Privacy, Location Services, and turn Off each Application that is not important to you.
Obviously you would tend to leave On Maps, Photo, Find Friends, Find My iPhone, Weather and Siri.
System Services: apparently, some of these can be demanding on Cellular Network usage...
Settings, Privacy, Location Services, and scroll down past the notes at the bottom of the list of Applications, and select System Services, and turn them all Off except Cell Network Search.
If the Maps Traffic service is important to you, turn it On, but be warned it may be a bit of a hog.
Notification Centre: work through each Application carefully, to determine what you really do need real time?
Settings, Notifications, select each Application, and turn Notification Centre, Off, if you do not need Notification in real time…
Siri: every iPhone User now understand how to use Siri…
However you should be aware that Siri support has been expanded significantly in iOS 6, to include operation of your iPhone, to send text, make appointments, find restaurants, make bookings, and handle your dictation. The catch is that Siri services contacts the Apple Server via the network to translate your voice, do the searches, and return your results. You can leave Siri On but be aware of using Siri, when you are only connected via Cellular Data, and low on Data Usage remaining…
Settings, General, Siri, Siri, On. by default,...
There is also a new setting included in several Applications which allow you to turn off the Cellular Data Connection while they are active...
Music: Settings, Music, Use Cellular Data, Off.
iTunes and App Store: Settings, iTunes and App Store, Use Cellular Data, Off.
Podcasts: Settings, Podcasts, Auto-Downloads, Use Cellular Data, Off.
Mail: you can set up mail to better manage Cellular Data Usage, if it suits your operation…
Settings, Mail, Contacts, Calendars, Fetch New Data, Push, Off, and set Fetch to Manually.
And select, Advanced, and for each Mail Account, Select Schedule, Manually.
And finally, here are a few more services you can probably do without, to further reduce Cellular Data usage…
Advertising: Settings, General, About, scroll down to Advertising, Limit Ad Tracking, On.
Diagnostics and Usage: Settings, General, About, scroll down to Diagnostics & Usage, Don't Send, On.
Some more tips…
For heavy data transmissions sessions on WiFi, switch to Airplane Mode, then switch WiFi back on again while your session is in progress. This mode will prevent iOS 6 from switching the Cellular Data midway through the session, should WiFi stumble….
One user reported: Turn turn off all aspects of iCloud: Safari, Contacts, Documents and Data, etc.
Do not remove the iCloud account, just turn off each service, then turn them all back on again…
Another user found that the Google Account was failing to connect, using up 4 to 5 MB every time the connection failed. Remove the Google account from iPhone, monitor for a while, then add it back again, an see if the problem is resolved.
Also check your other applications; for example, BBC News has a a share statistics switch set to On.
