Complete spec sheets for Apple's new iPhones revealed in China filings

For some reason, Apple never lists RAM memory capacity or battery size for its devices. This is why the specs sheets for the iPhone XS, XS Max and XR weren't really complete even after the phones' unveiling last week.

But thanks to the company's filings to China's Ministry of Industry and Information Technology (known as TENAA), unearthed by Macrumors via MyDrivers, we now know the full specs for all three of Apple's new iPhones.

Here's the rundown:

• iPhone XS: 2,658 mAh battery, 4GB of RAM

• iPhone XS Max: 3,174 mAh battery, 4GB of RAM

• iPhone XR: 2,942 mAh battery, 3GB of RAM

If these numbers are accurate, the iPhone XR, which is significantly more affordable than the iPhone XS, has a 10.7% bigger battery.

It's not entirely unexpected; after all, Apple does list iPhone XR battery life at up to 25 hours talk time, up to 15 hours of internet use and up to 16 hours of video playback. This is far better than the company's estimate of up to 20/12/14 hours for the iPhone XS, and better even than up to 25/13/15 hours for the iPhone XS Max. Also note that the iPhone XR, which has a 6.1-inch screen, is bigger than the 5.8-inch iPhone XS, and 0.1 inches thicker than both the iPhone XS and the iPhone XS Max.

Still, it's interesting to see such a significant difference between the $749 XR and the $999 XS. Note that the XR also trumps the iPhone X, which has a 2,716mAh battery.

4GB of RAM, while being sort of the norm in the world of Android smartphones, is a big leap for the iPhone. The iPhone X and the iPhone 8 Plus had 3GB of RAM, and the iPhone 8 only had 2GB of RAM.

All of this is quite interesting for anyone considering to "upgrade" from the iPhone X to the XR. Now we know that the XR will have a better processor, the same amount of RAM, and a bigger battery than the iPhone X, it's really starting to look like a sensible upgrade -- if you don't mind the LCD (instead of OLED) screen and the single (instead of dual) camera on the back.
