In September, Apple released its latest mobile operating system, iOS 9, which has some great new features like Apple News, better battery life, and split-screen multitasking. But a new feature, called Wi-Fi Assist, may be chomping through your data plans without your knowledge.
The new setting is automatically turned on when a phone is updated to the new OS. It attempts to ensure that users don’t experience any buffering when on a weak WiFi signal. The iPhone will detect when a WiFi signal lacks strength, and switch over to a cellular connection.
This feature is great if you are stuck in a place that is near wi-fi, like right outside your home or business or in a coffeehouse with a lot of users on the wi-fi. But there is a cost: The switch to cellular could mean you’re using more data from your monthly plan – with the potential of significantly more than you are used to using.
If you’re on a monthly fixed data wireless plan, it might be worth checking to see if your data consumption has risen. Keep in mind how much data you tend to use on a monthly basis and compare that to your usage since upgrading to iOS 9. Head to Settings > Cellular to see your data tally, and scroll to the bottom to see if Wi-Fi Assist is on.
This new features isn’t a bug. Apple is aware that it is an “issue”. Switching the setting to the off mode should bring your consumption back in line with your normal usage.
