The iPhone 13 is thicker and heavier than the iPhone 12

Yesterday, Apple announced its new flagship iPhones: the iPhone 13, iPhone 13 mini, iPhone 13 Pro, and iPhone 13 Pro Max. But while Apple's announcement livestream was full of details, some things were left out.

Fortunately, we've learned a bit more from Apple's updated website, including dimensions and weight, some info about specs, and the lineup of older iPhone models that will survive the culling that follows the introduction of a new flagship.

Thicker and heavier

The new iPhones are heavier than their immediate predecessors, and they're a little thicker, too. For example, the iPhone 12 weighed 5.78 ounces, but the iPhone 13 weighs 6.14 ounces. The iPhone 12 Pro was 6.66 ounces, but the iPhone 13 Pro is 7.19 ounces. This holds up across the line. And the iPhone 13 is 0.25 mm thicker than the 12; similar thickness differences are also universal.

This added heft may be mainly due to larger batteries—Apple said it rejiggered the internal components of the iPhones to make room for the batteries. Camera systems may play a part as well.

Same old RAM

Apple has occasionally bumped the amount of RAM found in its iPhones with new iterations, but that's not the case this year. Though Apple does not typically publish how much RAM a device has, MacRumors found references to the new phones' RAM configurations in Apple-made developer tool Xcode. The iPhone 13 and 13 mini have 4GB of RAM, and the Pro models have 6GB—the same as last year's iPhones.

The new iPhone lineup

When Apple introduces a new iPhone, it usually sunsets at least one older model while sometimes keeping others as lower-cost entry points to the iPhone product line.

According to Apple's online store, the iPhone 12, iPhone 12 mini, iPhone 11, and iPhone SE will survive. But the previously available iPhone XR, iPhone 12 Pro, and iPhone 12 Pro Max appear to have been retired.

This lineup may change when the new iPhones actually go up for preorder on Friday, but we doubt it.
