IPHONE 8 ($599)

New color filters in the camera produce truer and richer colors, while a new flash technique tries to light the foreground and background more evenly. Differences are subtle, though. The year-old model, similar in size to the iPhone 7, restores a glass back found in the earliest iPhones. That’s done so you can charge it on a wireless-charging mat, which also solves the problem of listening to music while charging. But with more glass, it’s even more important to get a case and perhaps a service plan.

IPHONE 8 PLUS ($699)

Again, the Plus version has a larger screen and a second lens. For those shots with blurred backgrounds, a new feature lets you add filters to mimic studio and other lighting conditions.

IPHONE XS ($999)

As with the iPhone X it replaces, the new XS has a display that largely runs from edge to edge, getting rid of the surrounding bezel along with the home button. Many tasks now require swipes rather than presses. The fingerprint ID sensor is replaced with facial recognition to unlock the phone. The display has about the same surface area as the iPhone 7 Plus and 8 Plus, while the phone itself is only slightly larger than the regular iPhone 7 and 8. Improved display technology means vivid colors and better contrasts, including black that is black rather than simply dark. You also get a dual-lens camera and software improvements for regular shots.

IPHONE XS MAX ($1,099)

This is essentially the “Plus” version of the iPhone XS. The phone itself is about the size of the Plus, but with more room for the display. This phone won’t feel big for existing Plus users, but think twice if you have small hands or small pockets.

COMING SOON

Consider waiting a month for the iPhone XR. Its display lacks the vivid colors, contrast quality and resolution of the XS, but the price tag is nicer at $749. As with the XS models, you’ll get an edge-to-edge screen to minimize wasted space. There’s more display than the regular XS, but the phone itself is also larger — just not as large as the Max. The XR won’t have the dual-lens camera, though Apple says it can offer the blurred-background effect with software.

WHILE SUPPLIES LAST

Apple quietly discontinued the iPhone SE , which is essentially a three-year-old iPhone 6S, packed in a body that’s smaller but thicker than the iPhone 7 and 8. Though the trend in phones has been to go bigger, some people preferred the smaller size — and the $350 price tag. Apple no longer sells it, though you can get it from some wireless carriers and other retailers, at least for now.

ALL IN THE MEMORY

If you get an SE, 7 or 7 Plus, consider spending another $100 to quadruple the storage. Those phones come with a paltry 32 gigabytes, just half of what’s standard these days. If you don’t upgrade, you risk filling up your phone quickly with photos, video, songs and podcasts.
