Back in September, Apple released its latest operating system, iOS 10 and all seemed great, fine and dandy ... except for one little feature.
Known as Wi-Fi Assist, the new feature aims to speed up your service by patching weak internet connections and switching between Wi-Fi and cellular data. This way, you won't see any annoying lags when uploading pages or watching videos. BUT, like we warned, the feature could be devouring your data.
Ashton Finegold, a teenager in San Francisco, learned that the hard way. While Finegold was surfing on his phone, he assumed he was connected to his house's Wi-Fi, and he should have been, except for the fact that the signal is weaker in his bedroom than anywhere else in the house. That means Wi-Fi assist kicked on, with no notice.
But, because Wi-Fi Assist is automatically turned on when iOS 10 is installed, Finegold had no clue he was eating up more than 144,000 MB of data and was racking up an enormous, $2,021.17 phone bill in the process.
"I thought my dad was going to kill me," he told CBS News.
According to Apple, Wi-Fi assist is meant to be a convenience that helps you stay connected to the internet even if you have a poor Wi-Fi connection. And, while you're loading up that webpage, it can certainly feel like one. But once your cellphone bill arrives, it's another story.
Unless you've got cash to burn, you can turn off Wi-Fi assist by going to Settings >> Cellular >> Wi-Fi Assist, and toggle it off.
