We probably won’t see Apple’s next mobile operating system iOS 9 until the Worldwide Developers Conference in June. The Cupertino company has typically chosen the developer-focused event to unveil its new software updates. But concept designers have started coming up with new concepts for what the iPhone and iPad software should look like.

iOS 9 Concept Features Night Mode, Siri Spell [VIDEO]

Features that users would love to see

The latest concept comes from Ralph Theodory, a tech enthusiast. Theodory’s concept is different because it focuses more on usability than pure aesthetics. For instance, he imagines the iOS 9 with a button in the app switcher that lets users close all apps at once rather than one-by-one. Theodory suggests Apple add a Night Mode to the operating system that will make is easier to read in the dark, while saving power.

His concept iOS 9 has Search in Settings to let do a quick search to find the setting you want. Theodory also proposes History in Settings that displays every single change you made in settings. It allows you to undo changes in just one tap. And then there is Siri Spell. Siri sometimes fails to recognize what you said. If that happens, Siri Spell will ask you to spell the word to learn it.

The iOS 9 concept also has a Smart Sleep Mode. Siri will pop up every five songs to ask the user if they were awake. If awake, they can answer via microphone or press any button. If Siri doesn’t receive any response in 10 seconds, it will automatically turn off music. An overwhelming number of usability features does not mean it lacks in terms of aesthetics.

Apple has started testing iOS 9

Theodory suggests Apple to add a Round Springboard that allows users to choose between three app display modes (app grid layouts) based on your taste. Google Analytics reports show that the iOS 9 is already being publicly tested. Apple Insider and MacWorld websites received several visits from devices running early builds of iOS 9.
