Smartphone leaker Steve Hemmerstoffer has dug up Apple’s filing with the Chinese Ministry of Industry and Information Technology’s Telecommunication Equipment Certification Center (TENAA) confirming that iPhone X has a 2,716mAh battery and 3GB of RAM.

In comparison, iPhone 7 and iPhone 7 Plus have 1,960mAh and 2,900mAh batteries, respectively. The recently released iPhone 8 probably comes with a 1,821mAh capacity battery and iPhone 8 Plus packs in a 2,675mAh cell, according to the TENAA listings for the devices that Hemmerstoffer uncovered earlier.

In other words, iPhone X has a bigger battery than the cell in iPhone 8, one of the longest-lasting iPhones on the market. Interestingly, the filing lists a rose gold version of Apple’s flagship phone even though iPhone X comes in just two colors.

The previous filing suggests iPhone 8 has 2GB of RAM and iPhone 8 Plus has three.

The 3GB of RAM on Plus models has become the norm due to increased data processing needs stemming from dual-lens cameras (for this reason, iPhone 7 Plus comes outfitted with 3GB of RAM, a gigabyte more than iPhone 7).

iOS and Apple’s A11 chip are, of course, fully optimized for this RAM.
