Apple’s official Smart Battery Case is engineered specifically for iPhone 6s and iPhone 6 to give users even longer battery life and protection.
It features soft microfiber lining on the inside which helps protect the iPhone inside, while the soft elastomer hinge design makes it easy to put the case on and take it off again. On the outside, the silky, soft-touch finish of the silicone exterior feels great in the hand.
With Apple’s Smart Battery Case, users can charge their iPhone and battery case simultaneously for increased talk time up to 25 hours, Internet use up to 18 hours on LTE, and even longer audio and video playback. With the Smart Battery Case on, the intelligent battery status is displayed on the iPhone Lock screen and in Notification Center, so users know exactly how much charge they have left. (Testing conducted by Apple in October 2015 using production iPhone 6s units and software paired with preproduction iPhone 6s Smart Battery Case units and production software. Video tests consisted of repeated playback of a 2-hour 23-minute movie purchased from the iTunes Store. Internet tests were conducted over 3G, LTE, and Wi-Fi networks using a dedicated web server, browsing snapshot versions of 20 popular web pages and receiving mail once an hour. Talk time tests were conducted by placing a cellular phone call. All settings were default except: Wi-Fi was associated with a network for all but the Internet 3G and Internet LTE tests; the Wi-Fi feature Ask to Join Networks and Auto-Brightness were turned off. All battery claims depend on network configuration and many other factors; actual results will vary.)
The battery case supports Lightning accessories, such as the Lightning to USB Cable (included with the iPhone) and works with the iPhone Lightning Dock (sold separately). Choose from two complementary colors: Charcoal Gray or White.

MacDailyNews Take: Imagine one of these for the iPhone 6/6s Plus – but we already get well more than a day out of the built-in battery anyway, now even multiple days of use since April due to the Apple Watches on our wrists.
