Apple has introduced its first ever iPhone battery case, entering the market with the Smart Battery Case ($99) for the iPhone 6s. Available in charcoal gray or white, the case looks like Apple’s other simple silicone cases with an added hump on the back for the extra battery.

The company’s “intelligent” battery will display its charge status on the iPhone’s lock screen and in Notification Center to give users a more complete picture of how much power they have left. The case is compatible with the Lightning cable that came with the iPhone or Apple’s iPhone Lightning Dock accessory, so it won’t need to be removed for charging.
The product page says the phone and case can charge simultaneously. Apple claims the case gives the phone up to 25 hours of talk time, 18 hours of Internet use over LTE and up to 20 hours of video playback.
