Finally Apple has come up with a solution that'll stop your iPhone from latching onto weak signals of Wi-Fi .
For example if you're connected to the Wi-Fi in your house, then you go outside in the garden , and while doing that, you check your email but can't seem to get any messages to load. It's because you're still connected to your home's Wi-Fi - and the signal is too weak. It's just spinning. After all, you're all the way outside and far from your router.
Typically, you'd have to shut off Wi-Fi under settings in order to totally disconnect from your close-but-not-close-enough router and then switch over to cellular data. With on cellular data, your emails and everything will load as normal, but it's tedious to have to go into settings and do all that. Why can't Apple let your iPhone automatically do this for you?
Well, with iOS 9, Apple plans to do just that. A new feature called Wi-Fi Assist has appeared in the latest developer beta of iOS 9. It will allow your iPhone to fall back to cellular data when Wi-Fi is poor. It looks like a simple toggle you can enable just once, and then it'll automatically do the switch for you - for good. No more disabling Wi-Fi altogether.
For those who are data-conscious or on uncapped data tariffs, Apple has introduced a warning prompt which sees the Wi-Fi symbol grey out before switching to cellular data, while also including an option to turn off Wi-Fi assist altogether.
The feature surfaced in the latest release of the iOS 9 beta which is currently only available to developers. Wi-Fi Assist joins the growing list of new software features that includes a special photo album for selfies and screenshots, the Apple News app and the option for high quality streaming in Apple Music.
iOS 9 is set for release alongside the next iteration of the iPhone which is rumoured to hit stores this September. iPhones from the 4S range onwards will be eligible for the latest update.
If you're a part of the iOS public beta, you can update now and start using Wi-Fi Assist right away. You can find it in Settings under the "cellular" section. If you're not interested in joining the public beta, you'll have to wait till September probably.
