Apple shares battery specifications for iPhones by giving usage ratings for talk time, internet use, video playback and more, but it doesn’t share the actual battery capacity for each model. Now, we’ve got specifics on the battery specs for the iPhone XS, XS Max, and XR.

Spotted by MyDrivers, documents from TENAA – China’s FCC equivalent – have revealed that the iPhone XS features a smaller battery capacity than the iPhone X. As we noted last week, the XS features an hour less talk time than the X, but an hour longer use when it comes to video playback. It can also be hard to tell how much a new processor like the A12 factors in to the battery life mix.

As it turns out, the XS features roughly a 2% smaller battery than its predecessor with a 2,658 mAh capacity compared to 2,716 mAh of the X.

As for the XS Max, as expected, it offers the largest battery Apple has put in an iPhone with 3,174 mAh with the XR coming in just below that with 2,942 mAh. Of the three 2018 iPhones, XR delivers the most use with up to 25 hours of talk time, 65 hours of audio playback, and 16 hours of video.

The TENAA filings also confirm previous reports that the iPhone XS/Max feature 4GB RAM while the XR has 3GB RAM.

We’ll see many more specifics of the 2018 iPhones revealed as iFixit will no doubt teardown the new models shortly.
