The Coolest Features in the iPhone XS, XS Max and XR Apple's XS lineup and entry-level iPhone XR don't have as many flashy features as their predecessors, but there are plenty of upgrades under the hood.

This year's new iPhones have arrived. The iPhone XS, iPhone XS Max and iPhone XR build upon the iPhone X, all coming with edge-to-edge displays, Face ID and a bevy of powerful cameras and processors.

The new flagship smartphone line doesn't feature as many dramatic changes or game-changing features as in years past. But combined with the rollout of iOS 12 on Sept. 17, the devices have plenty to offer consumers who want to upgrade. Read on for a rundown of the most notable new features and improvements the XS, XS Max and new entry-level iPhone XR.

Bigger, better OLED screens

The iPhone XS has the same size 5.8-inch OLED display as the iPhone X, but Apple says the phone's "Super Retina" display packs more pixels and 60 percent greater dynamic range than its predecessor. The massive iPhone XS Max sets a new display size record with a 6.5-inch display made up of 3.3 million pixels. (Photo by Justin Sullivan/Getty Images)

A12 Bionic processor

Most of the new phones' performance improvements stem from the A12 Bionic processor. The 7nm chip has 6.7 billion transistors and an 8-core dedicated machine-learning engine to analyze neural network data to figure out whether to run processes on the CPU, GPU or neural engine. Apple said the A12 can process 5 trillion operations per second, compared to 600 billion operations with the A11 chip. All of this gives you significant performance bumps, with apps opening 30 percent faster while using less power.

A 512GB storage option

Until now, internal iPhone storage maxed out at 256GB. The iPhone XS and XS Max double that, with a 512GB model for those who want to pay a few hundred dollars extra.

Adjust depth of field

Android devices such as the Galaxy Note 9 have been able do this for a while, but with the new iPhones you can now adjust depth of field in a photo after it's been taken. In photo-editing mode, look for the depth slider.

Beefed-up camera specs

The iPhone XS and XS Max still sport the same vertical configuration as the iPhone X with a 12MP wide-angle camera and telephoto lens. However, the latest smartphones come with more powerful sensors and improved True Tone LED flash with an advanced flicker-detect system. The front camera is still a 7MP lens but has a 2x faster sensor and improved red-eye reduction, detail segmentation and more thanks to the A12 chip.

Smart HDR

The A12 chip also powers what Apple is calling Smart HDR, which uses the phone's image signal processor and neural engine to combine multiple photos into one with techniques like zero shutter lag and highlight detail to take even better quality photos. More importantly, it also greatly improves low-light photos and is available not just in photo mode but also video, portrait, timelapse and pano to add more highlight detail to every shot.

Stereo recording

In addition to overall quality improvements thanks to Smart HDR and the more powerful camera, videos will also now capture stereo sound via the four microphones built into the iPhone XS for a richer sound experience.

Augmented reality and machine learning

The A12 chip improves overall performance, but also powers a range of apps and features coming in iOS 12. Cool features such as Memoji and better rendering of 3D objects in ARKit 2.0 all have machine learning running in the background to ensure everything looks smooth.

Improved waterproofing

A slight improvement, but the XS and XS Max bump up the iPhone's waterproof capabilities from IP67 to IP68. The new devices are dust-proof, and waterproof up to 2 meters deep and 30 minutes submerged.

Better battery life

The iPhone XS packs 30 minutes more battery life than the iPhone X, and the iPhone XS Max boasts an hour and a half more battery life thanks to its massive battery, the largest ever in an iPhone. Even the iPhone XR offers an hour and a half more than the iPhone 8 Plus.

Dual SIM

For the first time ever, the iPhones XS and XS Max will also have dual-SIM technology combining one physical SIM card with one eSIM. Apple is calling the process Dual Sim Dual Standby (DSDS), and it will allow users to keep two phone numbers, have two different plans or travel with a local data plan without having to swap out SIM cards. There will also be a new Intel modem to boot, so the new iPhones will finally work with all four major carriers (AT&T, Verizon, Sprint and T-Mobile) by default.

Two physical SIMs in China

Chinese iPhone users will also have dual SIM capability. However, instead of an eSIM (it's not as popular in China), Apple is releasing separate versions of the XS and XS Max in China that can use two physical SIM cards simultaneously.
