Here is a summary of the news.
According to Macworld, iOS 17 developer beta 4 includes references suggesting an iPhone with two batteries. MacRumors has also confirmed that this content is actually included in the beta version.
Currently, all the wording in the iPhone Settings app talks about one battery,
but it's unusual that plural expressions are used like this:
The 'batteries' in this iPhone are working normally.
The performance of the 'batteries' in this iPhone has been significantly degraded. You can have the battery replaced by an Apple Authorized Service Provider to restore it to peak performance and capacity.
The performance of the 'batteries' in this iPhone has been significantly degraded, and 'one of the batteries' is not identified as a genuine Apple battery. You can have the battery replaced by an Apple Authorized Service Provider to restore it to peak performance and capacity.
