Reducing data usage on IOS
- Monitoring Cellular Data Usage
With this new feature, embedded right in the settings, you can watch how much data your applications are using. Not only that, but you can disable data usage for an individual app in case it's using up too much data. To monitor your iPhone's data usage, head over to:
Settings -> Cellular and scroll down to Use Cellular Data For:
From there, you should see all your downloaded applications (as well as stock apps) and how much cellular data each app has used.
You can also check the data for things like Siri, your home screen, and other features that use up data by tapping on System Services at the bottom of the application list.
The statistics that show up under each app is the amount of data the app has used since the iOS 7 update. If you want to monitor it monthly (as you probably should), reset the statistics at every monthly cycle.
- Disable Background App Refresh
Apple now allows apps to automatically update and download content in the background. This feature can harm battery life and cause apps to use cellular data, even while you’re not using them. Disable background app refresh and an app will only use data when you open it, not in the background.
To access these options, open the Settings app, tap General, and tap Background App Refresh. Toggle apps to off if you don’t want them to refresh in the background, or disable the background app refresh feature for every app on your phone.
- Disable; Mail, Documents, Contacts, and Calendar Sync
Documents & Sync uses data however although the culprit is "Documents & Sync" it's more Sync and not Documents. To disable this you go to Settings>iCloud>Documents & Data Scroll down and switch use cellular data off.
To switch off everything in Documents you go to: Settings>iCloud>Documents & Data... Scroll down and have the customer turn off.
By default, your iPhone is set up to automatically receive new emails, contacts, and calendar events. If you use a Google account, it’s regularly checking the servers for new information. Either way, it’s downloading those emails as soon as they’re available.
If you’d rather check your email on your own schedule, you can. Open the Settings app, tap Mail, Contacts, Calendars, and tap Fetch New Data. You can adjust options here to get new emails and other data “manually.” Your phone won’t download new emails until you open the Mail app.
- iTunes Automatic Downloads
Again another option that allows your apps (up to 100MB now with iOS7) to be downloaded automatically, obviously when available, via your Mobile Data. You can set this to not download at all or only when you are connected to a WiFi access point.
To toggle the options go to Settings > iTunes & App Store > Use Mobile Data toggle this to off and it will force the phone to only update apps when the phone is connected to a WiFi Access point.
- Privacy Settings
This option has been available on iOS since 5 (I think), this setting as well can use Mobile Data to update your location even though you have not requested it. Although GPS technically doesn’t use mobile data but once it has updated it also allows an application to use a map to show your location which uses mobile data.
To turn off go to Settings > Privacy > Location Services, from here you can choose what app you want to access your location data, so be careful what you choose. If there is an app that you use all the time like Maps then you want to leave on otherwise you will need to come back here to keep turning it on and off, but go ahead and turn off what you don’t use. For some iPhones one can select while you are using only option instead of completely switching it off.
- Notification Centre
This was introduced in iOS7 and has been revamped in later versions but most people rarely use and prefer to switch it off. This may not use a lot of data but there are some options in there you can turn off that you don’t use.
To see what you can do go to Settings > Notification Centre, from there switch off all the app you don’t use such as if you don’t use Stocks turn it off, as that will always download the latest stock information.
- Multitasking Apps
Last thing to check is what applications you have opened and kill off what you aren’t using. When pressing the Home button the app is still running but in the background, think of it like minimising a window in Windows 7 the window is still there and open until you click on the ‘X’ button. Please note that this may save a lot of data but it will save battery life as well as whatever data it is chewing up
To close the application double press the Home button and then swipe up to close the application properly.
- Switch to a Lightweight Browser
Switching form the mobile browser to browsers like Chrome beta or Opera Mini are alternatives that feature data compression and optimization to help reduce usage.
- Third party data Monitors
Apple IOS does not have an inbuilt data monitor like android, therefore you are advised to downloada third party data monitor from the App Store. The following are recommended:
- Data Monitor - is a very decent app. It’s good especially when you want to know, how much data has been used on cellular and Wi-fi separately
- My Data Manager - This one was actually one of the finest apps in the store garnering 5-star reviews. With the latest update they removed per-app usage stats. Nevertheless, if you’re not much after per-app tracking and need just a good overview of how much you’ve used, how much is left and how much you use of your daily budget.
- DataMan Next - Probably the best app ever for data monitoring that’s fantastic. There are no bells and whistles here. All you get is an interface that shows your data usage (as a percentile of total allowed). Works with all carriers, tracks both cellular and Wi-fi usage and comes with four alerts that change hue according to the value.
- DataWiz - One of the best of the lot but only if you’re into a clean, minimal and interesting interface.
DataWiz is great if you have your cellular enabled all the time. It “predicts” your usage based on patterns you’ve showed over the week and that’s kind of useful if you’re looking to change data plans. It may however slack in accuracy if you turn-off cellular data to conserve battery.
