The recent release of Apple iOS 9 included extra features such as Apple News, better battery life, and split-screen multitasking. There is also a new feature called “WiFi Assist” which turns on by default once you update to iOS 9.
WiFi Assist detects if your WiFi speed is slow and switches your iPhone into using mobile data there are no buffering issues. This setting will be ideal for users that want a seamless experience when viewing content. It will also be convenient if you live in a house and your WiFi connection isn’t all that reliable. If you do utilise this feature, you will need data.
If you don’t have much data in your mobile plan, WiFi Assist might create bill shock. For those who are unaware of this feature and fall into this category, they may very well burn up their data limit whilst under the impression they are using WiFi. The solution to prevent this would simply be to turn off the feature. Since it is so simple to utilise or to disable this feature, we think it is a good feature.
