Tucked in an electronics industry report about the supplier of batteries for the upcoming iPhone XR sequel we find the actual capacity of the pack in the tentatively named XR 2. The source muses that Apple may be done with hardware and iOS optimizations, and seems to be now betting on larger battery packs to make its phones last longer on a charge, just like Samsung or Huawei are doing.

The iPhone XR 2 battery pack orders are reportedly granted to China’s ATL (Amperex) which are the same guys that got the order for non-exploding Galaxy Note 7 packs after the infamous Samsung SDI batteries started catching on fire. The new battery capacity is said to be 3110 mAh, which would make the iPhone XR’s successor with the largest single-cell battery pack in an iPhone ever.

While this is just a 5% increase over the 2942 mAh capacity in the iPhone XR, the XR 2 is also expected to come with Apple’s A13 processor made with a second generation 7nm process that should reduce battery draw further.

Coupled with the new pack and the frugal display resolution, the iPhone XR (2019) should therefore last longer on a charge than the already best in that regard iPhone XR. It scored more than 11 hours of screen-on time in our grueling test, ahead of any iPhone we have tested so far. The XR 2 may very well break the 12-hour mark which would place it in a special endurance club of its own, and not only among phones in the iOS camp.

Here’s how the iPhone XR (2019) may look like, as rendered by graphics artist Hasan Kaymak based on rumors, leaked CAD drawings, and analyst expectations.
