In gee that's a simple solution, why isn't that already a thing news, Apple has built a new Wi-Fi feature into its newest iOS.
Apple products never want to let go of Wi-Fi. The signal might be terrible, but iOS will cling to any available Wi-Fi – even if it's so slow as to render your phone a brick.
Instead of simply switching over to cellular, you'll sit there with your Wi-Fi spinning, trying to load up Google Maps. Or Spotify. or whatever.
Unless of course, you turn off Wi-Fi altogether.
Well, iOS 9 fixes this problem.
Apple has a new feature called Wi-Fi Assist, and when selected, it automatically switches over to cellular data when Wi-Fi connectivity is weak.
Of course, if you're worried about your data you can turn this feature off. It's not mandatory.
9to5Mac first spotted the new feature in iOS 9 beta for developers. The new iOS also offers 15 new wallpapers, Beats 1 and Apple Music CarPlay support, Handoff support for the podcasts app, and more. Not a developer? You'll have a chance to grab it soon.
