Best Way to Save Data on IOS 9 Devices

If you have a Apple Device running iOS 9 or later, then you need to know this.

In the iOS 9 update, Apple has made it so by default, your phone is allowed to use cellular data while connected to wifi. What this means is when you're using your wifi at home, it can increase your speed by using your culleler data. This pretty much burns your data for no reason.

We'll cover how to fix this in this two step, super easy, instructable.

Step 1:

So the first step is to go to Cellular in the settings menu, it is after the Wifi and Bluetooth tabs.

Step 2:

Now go to the bottom of the page, there is a slider labeled Wifi Assist, turn this off.

That's it, now your Phone won't waste your data while at home.

If you have any problems, please leave it in the comments and I will try to help.

    Very nice! This explains a lot, such as why I got a data overuse warning now that both our phones are using iOS 9.xx.

    What about all the apps listed on the same page that are on by default? Does their on/off state default to the setting of this switch, or do they all have to be individually turned on or off regardless of the wifi assist switch setting?

    The wifi assist allows your phone to use the cellueler network when connected to wifi, to boost speed. The sliders next to the app allow you to stop the apps from using the cellular network, sadly each one is turned on by default and have to be turned off individually.
