We first heard rumors about the cases — which all cost $129 no matter which phone they fit — back in December. As seen in that report, the power pack on the back of the Smart Battery Case is a little more streamlined than on the version first unveiled in late 2015 for the iPhone 6 and 6 Plus.

This new cases promises a silicone exterior, available in either white or black, combined with a microfiber lining inside the case to keep your phone comfortable. The cases will work with Qi-certified chargers, Apple says, so you'll be able to charge them wirelessly. In fact, since you can charge the phone and the case at the same time, you'll never even need to remove your iPhone, though the case's elastomer hinge design is aimed to allow you to do so easily.

Expect increased talk time of up to 33 hours with the iPhone XS Smart Battery Case, which Apple says is only compatible with the iPhone XS even though it's the same size as 2017's iPhone X. Apple claims you can also get up to 21 hours of internet use and 25 hours of video playback.

With the iPhone XS Max Smart Battery Case, you can expect up to 37 hours of additional talk time, 20 hours of internet use and 25 hours of video playback.

The iPhone XR Smart Battery Case promises an extra 39 hours of talk time, 22 hours of internet use and 27 hours of video playback on a charge.

The iPhone XR already lasts a long time on a charge, holding out for 11 hours, 26 minutes on our battery test, which involves continuous web surfing over LTE until the phone runs out of juice. That's good enough to place the iPhone XR on our list of longest-lasting smartphones, so a Smart Battery Case could let you go even longer between charges. With battery test times of 9:41 and 10:38, respectively, the iPhone XS and XS Max might benefit from a case that adds a lot more battery life.
