The all-new Smart Battery Case for iPhone 6s gives you extra battery life with the look and protection of an Apple-designed case. Combined with the Smart Battery Case, iPhone 6s provides up to 18 hours of battery life for browsing the web, up to 20 hours of watching HD video, and 25 hours of talk time.* The Smart Battery Case also works intelligently with your iPhone to charge simultaneously when you’re plugged in, so both case and iPhone will have more than enough battery life to get you through the day, and then some. The soft elastomer hinge and one-piece design makes it easy to put the case on and take it off. You can even connect it to any Lightning accessory, such as the Lightning Dock. And iOS 9.2 allows you to see the battery status of your iPhone 6s, your Smart Battery case, and even your Apple Watch, all in one place. Available in Charcoal Gray and White.
*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.
