Apple doesn’t list the battery capacities of the new Apple Watch Series 9 and Ultra 2 models, but MacRumors discovered this information in a Chinese regulatory database today, and we describe our findings below.

Apple Watch Series 9
According to the database, which only provides Apple model numbers rather than product names, the 41mm and 45mm Apple Watch Series 9 models appear to be equipped with 282mAh and 308mAh batteries, respectively. These capabilities are unchanged compared to the equivalent Apple Watch Series 8 models, which makes sense given that Apple says the Series 9 models have the same 18-hour battery life as the Series 8 models.

As for the Apple Watch Ultra 2, it appears to be equipped with a 564 mAh battery, which is about 4% larger than the 542 mAh battery of the original Apple Watch Ultra. However, Apple says the Ultra 2 has the same 36-hour battery life as the original Ultra, likely because it has a brighter screen and other new features.

New features for both Apple Watch Series 9 and Ultra 2 include brighter displays, a faster S9 chip, a new “Double Tap” gesture to interact with the watches without touching the screen, and more. Both new models have been available to order since Tuesday and will begin reaching customers and launching in stores on Friday, September 22.

MacRumors I also found the same battery capacities for what appears to be the iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max as reported today. We couldn’t find a listing for the regular iPhone 15 battery.
