References in iOS 13.2 further point to Smart Battery Cases for iPhone 11, Pro

The Smart Battery Case is an Apple-produced accessory for the iPhone lineup. The case houses an extra battery within the case's back to provide more power to the iPhone throughout the day.

While unusual in its design, the accessory has been popular enough for Apple to produce multiple versions. And, the second sign has popped up that suggests that Apple is going to introduce an update to the case for the latest iPhone launches.

References to three new models of Smart Battery Case were originally found within the code of iOS 13.1. The model numbers found in code of the under-beta operating system are A2180, A2183, and A2184.

New graphics found on Monday by MacRumors further emphasize that the product is coming.

While there is no indication of what models they relate to, the closeness of the numbers found the iOS 13 code to the previous models, suggest they are all related, and are for the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max, though which model number relates to which iPhone variant is still a mystery at this time.

There isn't any sign of when Apple will introduce the next wave of Smart Battery Case models. Apple introduced the previous versions for the iPhone XS, XS Max, and iPhone XR in January of 2019 after similar discoveries in 2018.
