Apple released its Smart Battery Case back in 2015 that featured controversial design. It was designed for the iPhone 6, 6S and now, it is also available for the iPhone 7. However, since the launch of the iPhone X, the design has changed radically and we have been expecting a new Smart Battery Case. However, up until now, we haven’t seen any. Now, we are hearing that Apple may be working on a new Smart Battery Case for the new iPhone XS models. Let’s see some more details on the matter.

In the latest watchOS 5.1.2 beta 2, a new icon has been discovered. The icon is used to display the charging status of the Smart Battery Case within the battery widget. This is the same component which predicted the new 2018 iPad Pro without a Home button.
