Apple has talked a lot about the iPhone XS and the iPhone XR, but you won’t hear anything about their battery sizes. It’s typically been a subject the Cupertino-based company avoids. As other companies discuss capacity and efficiency for their batteries, Apple remains quiet on that because it believes hardware and software optimizations lead to true longevity.

Yet there’s no hiding this information forever. In a new filing with the Chinese government, the battery sizes for all new iPhone models went public.

Here are the battery sizes, according to MyDrivers:

– iPhone XS: 2658mAh

– iPhone XS Max: 3174mAh – iPhone XR: 2942mAh

With this information, we’re able to see how the iPhone XS and its siblings stack up against competitors on paper. The iPhone XS has a smaller battery than most flagships, but the iPhone XS Max and the iPhone XR are about average. Apple often uses smaller-than-usual battery sizes.

It’s also no surprise because, for several years, Apple’s customers have whined about disappointing battery life. All of them, however, should return all-day runtime. The results just won’t match what other flagships get. Keep those chargers on-hand, folks.
