Engineered for iPhone XS Max, the Smart Battery Case gives you even longer battery life while offering great protection. Inside, a soft microfibre lining helps protect your iPhone. And on the outside, the silky, soft-touch finish of the silicone exterior feels great in your hand. A soft elastomer hinge design makes it easy to put the case on and take it off.
The Smart Battery Case is compatible with Qi-certified chargers. You can charge your iPhone and battery case simultaneously for increased talk time of up to 37 hours, Internet use of up to 20 hours, 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 Centre, so you know exactly how much charge you have left.
The case can be charged even faster with USB-PD–compatible chargers. It also supports Lightning accessories, such as the EarPods with Lightning Connector (included with your iPhone) and the Lightning Digital AV Adapter (sold separately).

*Testing conducted by Apple in November 2018 using pre-production iPhone XS Max units and software paired with pre-production iPhone XS Max Smart Battery Case units and pre-production software. Talk time tests were conducted over a Voice over LTE (VoLTE) network. Internet tests were conducted over LTE and Wi-Fi networks using a dedicated web server, browsing snapshot versions of 20 popular web pages and receiving mail once an hour. Video tests consisted of repeated playback of a 2-hour 23-minute movie purchased from the iTunes Store. All settings were default except: Bluetooth was paired with headphones; Wi-Fi was associated with a network for all but the Internet LTE test; the Wi-Fi feature Ask to Join Networks, Auto-Brightness and True Tone were turned off. All battery claims depend on network configuration and many other factors; actual results will vary.
