According to Apple, iOS 9 has the biggest adoption rates compares to all other iOS version before. At September 19th, 50% of iOS devices already made the switch to the latest version of iOS. With this many devices upgrading, there was no doubt that there will be some sort of problems with the first version of the latest iOS. This time, it’s all about your mobile data.
A big number of users reported spikes in their mobile data usage, direct after upgrading to iOS 9. This problem is connected to the newest iOS feature Wi-Fi Assist. This setting, which is switched on by default on iOS 9, is supposed to support you “stay connected to the Internet even if have a poor Wi-Fi connection“, by switching over to mobile data, if you have a bad Wi-Fi reception or if the connection is slow in general. However, Wi-Fi Assist might cause more problems than actually help you.
Apple was already sued for the data draining iOS 9 settings
Indeed, Apple was slapped with a $5 Million USD class-action lawsuit for not notifing users of increased data usage and enabling this draining setting by default on all devices running iOS 9.
The lawsuit demands that Apple “downplays the possible data overcharges a user could incur” from Wi-Fi Assist. – AppleInsider
After the initial complaint Apple changed its website saying that Wi-Fi-Assist “may use more cellular data”.
To clarify the problem, there are some things Wi-Fi Assist doesn’t do:
- It doesn’t drain data for apps running in the background
- Wi-Fi Assist will not connect to mobile data if you’re data roaming
- Apparently, it doesn’t turn on when streaming audio, video or downloading attachments in third-party apps
How to switch off Wi-Fi Assist on the iPhone / iPad
Turn off Wi-Fi Assist is totally easy. Simply open your Settings, go to Mobile Data (Cellular), go down to the very bottom and toggle the On/Off switch next to Wi-Fi Assist.
If you’ve done that you’ll likely see an overall decrease in your mobile data usage in the future.

- Open Settings > General
- Tap on Background App Refresh
- Toggle the On/Off switch next to the apps that you don’t want to use mobile data in the background
