As noted by Venkatesh Babu on Twitter, the voltage listed for the battery in these filings is high enough that the product in question is unlikely to be an iPhone or iPad. This means it’s likely some sort of MacBook, but details here remain unclear.
The 4,380mAh battery listed in this filing is relatively small in terms of the Mac but it could be destined for the MacBook Air. For example, the 16-inch MacBook Pro features an over 8,000mAh battery. The 13-inch MacBook Air has roughly a 5,100mAh battery. The wattage listed here is also interesting. The filings indicate that the Mac in question as a 49.9-watt-hour battery, which is exactly the same as the 13-inch MacBook Air and lower than the 13-inch and 16-inch MacBook Pro.
With all of this in mind, it seems clear that this battery is likely headed to a MacBook Air of some sort or even a revival of the 12-inch MacBook.
MacDailyNews Take: Is this battery for the first publicly-released Apple silicon Mac?
