"Hey Siri" support and possibly wireless charging case alongside AirPower charging mat.
iOS 8 to Include Battery Usage Per App and Much More
Along with the features that were demoed on stage, an iOS 8 graphic displayed some additional functions that went largely under the radar, many of which look quite interesting. For example, iOS 8 will apparently display battery usage by app, a handy feature that will let users monitor the battery drain of specific apps, shutting down those that are drawing too much power.
iPads will gain the ability to take Panoramic photos like the iPhone, while the Camera will gain an instant burst mode, a timer mode, and separate controls for focus and exposure. iBooks will support an auto night mode and the ability to organize books by series, while notifications will include travel time.
A mysterious Tips app, which was first depicted in an early screenshot of iOS 8, is also mentioned, though it is unclear what this app will do. It is possible Tips will provide iOS users with information on lesser known iOS features, serving as a tutorial app for those who want to learn the ins and outs of their devices.
An "In Case of Emergency" card will be added to iOS 8, displaying contact information and possibly health-related information as well. Users will be able to use Siri to purchase iTunes content, Notes gains a new rich text editing feature, and RSS feeds are displayed within Shared Links in Safari.
Other mentioned features offering unknown functions include Place cards in other apps and Speak Screen.
Finally, there are also several accessibility improvements coming, including an Alex voice, Braille keyboard, improved zoom, and multi-device support for MFi hearing aids. Guided Access, which limits an iPad or iPhone to opening a single app, will gain time limits, a countdown timer, and Touch ID integration.
These are of course, only a small selection of the hundreds of new features and minor functions that will likely be added to iOS 8 as it is in development. iOS 8 is available to developers immediately, while the public will get access to the new mobile operating system later this year.
