*Testing conducted by Apple in August 2016 using pre-production iPhone 7 units and software paired with pre-production iPhone 7 Smart Battery Case units and pre-production software. Video tests consisted of repeated playback of a 2-hour 23-minute film 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 mobile phone call. All settings were default except: Bluetooth was paired with headphones; 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.
