iOS 9 comes with a feature (Wi-Fi Assist) that might be eating your cellular data, here's how to disable it

iOS 9, being an evolutionary step in Apple's mobile OS, comes with a wealth of features that greatly expand the feature mix of Apple's operating system. Low Power mode, Siri's gained proactive powers, and the numerous performance improvements are just some of the more important iOS 9 highlights, but there are many others that hardly received any attention.

One of these is Wi-Fi Assist, a new iOS 9 feature that sounds pretty handy on paper, but might be secretly stabbing a large portion of users in the back. What this feature does is basically switch to cellular data in case the Wi-Fi network you're connected to is poor or experiencing some issues at the moment. So far, so good, but that feature comes enabled by default. 

This might, without a doubt, be a pretty serious problem for all those iPhone or iPad users that have a fixed monthly allowance for cellular data. Admit it, how often do you check the connection indicator in the status bar of your iPhone when you're, say, at home and usually rely on your Wi-Fi network? Casually watching YouTube videos or nonchalantly browsing heavy websites might easily eat your data allowance for the month.

Here's how to disable Wi-Fi Assist and make sure that your iPhone won't switch back to cellular data if the Wi-Fi network has poor connectivity.

Another copy from their idols, Samsung. That one is called download booster and uses both wifi and LTE data to boost the download of large files

Actually that's not even what this is. This just disconnects when the WiFi connection is slow or weak. It's been a part of AOSP for years. WiFi booster is Samsung only for now and is a great feature for unlimited data users like myself.

I dont think this is a new feature.. ios has this before too, if u keep your wifi and cellular open, when u have no wifi connectivity it automatically connects to cellular network... why we need this extra feature now?

The difference is that now it does not wait until no wifi is found. It will switch you to cellular when your connection starts to get weak.

Awesome when you leave the house or work. It seamlessly switches to cellular. Or vice versa. As the article says, you can also disable it.

Smart network switch? The thing I've had on my S5 for almost 2 years?

Wifi-Assist is NOT switching the wifi network to the cellular network. That has been a default feature since the first iPhone. If anyone read the article, they would see that Wifi-Assist uses your cellular data instead of wifi when the wifi signal has low quality.
