Here are the biggest differences between the $1,000 iPhone 11 Pro and last year's iPhone XS

The iPhone 11 Pro and iPhone XS have the same size screen, but the iPhone 11 Pro got a slight upgrade: the phone has a Super Retina XDR display, compared to the iPhone XS 's Super Retina HD display. While both screens are OLED, the 11 Pro's should look slightly richer.

The 11 Pro also has a higher brightness of 800 nits, compared to 625.

The iPhone 11 has 3 rear camera lenses: a 12-megapixel wide-angle lens, a 12-megapixel ultra-wide camera, and a telephoto lens with Night mode and the ability to take 4K video at 60 frames per second. This phone will also allow you to take "slofies," thanks to an improved front-facing camera. It also has improved HDR for photos.

The iPhone XS still has a high-quality camera, but it lacks the ultra-wide lens and new camera modes.

Apple says that the A13 is capable of 1 trillion operations per second.

The iPhone XS has the older — but still powerful — A12 chip.

The iPhone 11 Pro comes in four colors: silver, space gray, gold, and the new midnight green.

The iPhone XS comes in three offerings: silver, space gray, and gold.

Battery life in the iPhone 11 Pro is about four hours longer than in the iPhone XS. Apple called the upgrade "our most dramatic leap in battery life ever."

The 11 Pro will come with a faster, 18-watt charger, which should charge your phone 50% in 30 minutes.

The iPhone XS comes with a traditional 5-watt charger.

Apple has offered 3D Touch on its devices for a few years as a way to boost productivity: rather than having to open an app, you could press using 3D Touch to open a shortcut menu. 3D Touch created different levels of responsiveness based on how much pressure users applied, creating a distinction between a hard touch and a soft tap.

New this year, Haptic Touch will respond to the length of the press, not the force of the tap.

The iPhone 11 Pro is waterproof in up to four meters for 30 minutes, compared to two meters for 30 minutes for the iPhone XS.

It's not a major difference, but the iPhone 11 Pro weighs 6.63 ounces, versus the iPhone XS, which weighs 6.24 ounces.

• Size: both phones have 5.8-inch screens.
