While Apple shares battery specifications for each iPhone battery via talk time, Internet use, video playback and more, it doesn’t share the actual battery capacity for each model.
This may have changed, as MyDrivers has published documents from TENAA, China’s FCC equivalents which reveal that the iPhone XS features a smaller battery capacity than the iPhone X. As 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 such 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.
The iPhone XS Max, as expected, 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 confirmed that the iPhone XS and iPhone XS Max feature 4GB RAM while the XR has 3GB RAM.
Stay tuned for additional details as they become available.
