Apple has released new smart battery cases for the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. The new cases are designed to extend the iPhone's battery life, allowing users to do more with their Apple-branded handset.

The new smart battery cases, previously discovered inside the iOS code, look similar to the ones made for the iPhone XR, iPhone XS and iPhone XS Max, the only major difference being the camera cutout at the back. The new cases have a square-shaped opening designed to accommodate the new camera setup on the iPhone 11 series devices.

Aside from the cutout, the new cases also add a new detail not present in the older cases: a dedicated camera button. This button can be used to launch the Camera app whether the iPhone is locked or unlocked. Apple said a quick press takes a photo, while a long press captures a QuickTake video. The camera can be used for selfies as well.

The iPhone 11 series smart battery cases are designed to keep iPhones safe. Each case has a soft microfiber lining inside to keep the iPhone protected (especially from scratches), and has a soft-touch silicone exterior. The cases also make use of a soft elastomer hinge design so that it would be easy to put the case on and off.

Like their predecessors, each case is compatible with Qi-certified chargers and will charge simultaneously with an iPhone. Those who want to charge the cases, and the iPhones inside, faster can use USB-PD-compatible chargers. Apple promises that fully charged smart battery cases will add up to 50% battery life that translates to longer talk time, longer audio and video playback, and more.

Cupertino said added battery life depends on a variety of factors, including network configuration. For reference, Apple tested the battery cases using preproduction iPhone 11 series units paired with preproduction smart battery cases. Tests involved repeatedly playback of a 2-hour and 23-minute movie. Settings were set to default, with a few exceptions such as Bluetooth and Wi-Fi use.

All smart battery cases are available for purchase now via the online Apple Store. Each case costs $129, and can come in Black, White and Pink Sand for the iPhone 11 Pro and iPhone 11 Pro Max ; and Black and Soft White for the iPhone 11.
