It seems that lately the law firms that work for Apple they do not give enough to meet the demands The last one that appeared relatively recently would refer to the Wi-Fi connection assistant in iOS 9, a feature that would be designed to make the user experience even better if possible but in exchange for "not informing" the user properly of its functioning.
I refer to this small detail because it works in a somewhat curious way, that is, when the Wi-Fi signal is not strong enough, this assistant automatically toggles mobile data usage with Wi-Fi signal To compensate for the lack of speed, in this way the experience continues to be good, however that costs the data fee behind the user's back, which does not seem to have been amusing to a good part of the users.
In early October, Apple already confirmed that data expenditure is very small and wanted to clarify the situation a bit at this point. In addition, he also published a support document that explains that when a user is on a data itinerary, this feature only works with applications that are in the foreground and not with those that need to use data in the background such as music, video or streaming applications.
The plaintiffs are William Scott Phillips and Suzanne Schmidt Phillips who received some invoices with extra charges on its data rates after upgrading to iOS 9. The lawsuit notes that Apple did not clearly explain the feature until the media picked up on user complaints, but that by that time it was too late for users. plaintiffs.
If you are interested in deactivating this function, you just have to go to Settings> Mobile Data> Wifi Assistance (very bottom).
