After the introduction of Apple’s iOS 9 some users found that their Mobile data/Cellular data was being gobbled up more rapidly than before.
The reason for this was Apple’s new WIFI assist feature which uses mobile data if your WIFI is flaky.
If you have a similar case, you can turn this feature off in Settings > Mobile Data then scroll to the bottom of the page where you can turn off Wi-Fi Assist.
In reaction to the discourse over the new feature, Apple has admitted that users “might use more cellular data” in a new support document about the feature.
The issue is that the feature is turned on by default, so users who have a limited data allowance may wish to turn it off, but if they are unaware of its existence they will have no idea about the cause of their data loss.
Apple has limited the feature to some extent, though: it won’t work when you are data roaming in another country and not all apps can take advantage of the feature, for example video and audio streaming apps are exempted. However, Apple’s Safari, Mail, Maps, and Apple Music do utilize the feature.
UPDATE: Despite Apple’s attempts to rectify things and warn users of the feature, the company is now in trouble over WiFi Assist.
At the end of October, a Californian couple, filed a lawsuit against Apple for not warning users about it’s new feature. This might result in a $5 million payout if the lawsuit is successful.

In the summer of 2013 Photo Stream started to regularly hit our data allowance, having signed up to a friend’s feed, and started sharing one of our own. Back then, when you turned off Photo Stream in Settings >iCloud> Photos and then toggle My Photo Stream on, it looks innocent enough, claiming as it does it will “Automatically upload new photos and sendto all of your iCloud devices when connected to Wi-Fi.” This may be the case, but we were getting sent photos from our friend’s Photo Stream when we were on 3G networks, it surely wasn’t a very cellular data friendly service.
Luckily the iOS 7 update, bring the functionality to manage Photo Sharing. You could turn off iCloud Photo Sharing (at Settings > Photo & Camera), which would stop your phone from downloading images from other people’s shared photo streams that you subscribe to (you can still download them on your Mac or another device).
