Engineered for iPhone 11 Pro Max, the Smart Battery Case gives you even longer battery life while offering great protection. Inside, a soft microfiber 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.
When fully charged, the Smart Battery Case delivers up to 50% longer battery life.
Charge your iPhone and battery case simultaneously for increased talk time, internet use, 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 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) or the Lightning Digital AV Adapter (sold separately).
