iOS 8 Hidden Features Video: Battery Usage By App, Hidden Photos, Siri Hands-Free, and More
Outlined in the video below are some of the most interesting and handy tweaks in iOS 8, including automatic credit card scanning, expanded weather options, quick access to contacts, a hands-free mode for Siri, hidden photos, and more.
We've been collecting and cataloguing minor feature changes to iOS 8 since the first beta was released, documenting the development of new features and providing a one-stop location for all the changes that have largely gone under the radar.
A complete list of all of the hidden features in iOS 8 can be found in our dedicated Hidden Features Roundup, which also serves as a way to see the progress iOS 8 made over the course of the beta testing period.
For example, in beta 4, Apple introduced a Tips app that offers iOS 8 users information about all of the new features in the operating system. Beta 5, meanwhile, added location information to photo collections in the Photos app, and beta 4 saw a Control Center redesign.
We've also compiled a walkthrough of all of the major features introduced with iOS 8, which can be found in our iOS 8 Roundup.
iOS 8 can be downloaded immediately for free. It can be installed on the iPhone 4s and later, 5th-generation iPod touch, iPad 2 and later, and the iPad mini.
