Galaxy S24 Ultra: What’s Changed From the S23 Ultra (and Should You Upgrade)

Samsung unveiled its newest Galaxy S24 phones at its Unpacked event. The most premium of the lot is the Galaxy S24 Ultra, which has several new features over last year’s model. What’s changed from the S23 Ultra, and should you upgrade? Probably not, but let me explain. 

First, here’s what’s changed. The S24 Ultra has a nominal amount of upgrades on its predecessor (mainly under the hood), but is pricier, starting at $1,300, while the S23 Ultra had a $1,200 price tag at launch (and can probably be found for cheaper now).

The S24 Ultra visually looks identical to its predecessor, with broadly the same design and rear camera layout. There are subtle differences. For instance, Samsung’s new high-end phone has a titanium frame, which should be tougher than the aluminum frame on the S23 Ultra.

For the S24 Ultra, Samsung dispensed with the curved edges of the display found on the S23 Ultra, leaving a flat front (Samsung claims it has 47% less bezel on the sides). That new screen is also brighter with a maximum of 2,600 nits (the S23 Ultra maxed out at 1,750 nits) and thus easier to see in bright daylight. The S24 Ultra’s screen is also made of Corning’s newest and toughest material, Gorilla Glass Armor, while the S23 has Corning’s Gorilla Glass Victus 2. 

In short: it looks the same but should be tougher and have a potentially brighter screen. The S24 Ultra also has an improved cooling system with a vapor chamber that’s twice as large and two added layers of thermal insulation, so we’d expect it to maintain better framerates and temperatures when running performance-intensive operations, like gaming.

As for cameras, the S24 Ultra inherits most of its predecessor’s lenses and sensors but does use a 50-megapixel 5x optical telephoto camera in place of the 10-megapixel 10x optical camera in the S23 Ultra. While the new camera has a shorter optical length, its higher megapixel count should mean photos taken with it are sharper than those shot with the S23’s 10x optical camera. (We’ll know for sure when we can compare both phones’ photo capabilities side by side.) To get to 10x optical length, the S24 Ultra shoots with its 5x optical camera and crop zooms in.

The S24 Ultra is powered by a Snapdragon 8 Gen 3 chipset, which is faster than the Snapdragon 8 Gen 2 in the S23 Ultra. Configurations have also been simplified in the new premium phone: you can only get 12GB of RAM and 256GB, 512GB or 1TB of storage (no 8GB RAM option, as there was in the S23 Ultra). The rest of the hardware remains relatively unchanged, although the S24 Ultra should get a minor battery efficiency boost thanks to its newer chipset.

The big difference between the new phones, at least at the launch of the S24 Ultra, is the new phone’s generative AI capabilities, called Galaxy AI. The most noteworthy is Circle to Search, which lets you trace an area on your screen with your stylus or finger to have your phone look up what you’ve circled without ever having to leave the app you’re in. It’s conceivably great for looking things up, like identifying landmarks in the travel photos your friend sends over or trying to track down fashion items in someone’s outfit.

The S24 Ultra (and the rest of the S24 lineup, to be clear) has other generative AI capabilities, like summarizing notes and live translations during phone calls. It can also suggest different tones for text messages depending on who you’re talking to, recommending more formal tones for bosses or casual tones for friends. Generative AI photo tricks let users do things like move or delete some elements, expand photos beyond their original boundaries or correct the tilt of an image, then use AI to fill in the backgrounds and empty areas.

Some of these generative AI features can be processed locally, like live translation, while others require sending requests to the cloud. The S24 Ultra does have a toggle in its settings to require generative AI requests to be performed on the device, which helps keep what you’re asking (and what your phone is addressing) private.

The kicker? Galaxy AI is coming to some older Samsung phones, including the S23 series, at some point in the future. While Samsung hasn’t said when to expect them, these features should come to the S23 Ultra in time.

There are other non-generative AI upgrades the S24 Ultra has over its predecessor, like making photos more stable during movement and improving low-light photography. The S Pen accessory is more or less unchanged from last year. 

There is one more upgrade that’s worth mentioning: Samsung expanded how long it’s pledging to support its newest phones. The S24 Ultra comes with Android 14 and will get seven years of Android software and security patches, up from four years in the S23 Ultra (which comes with Android 13). That’s big. For sustainability, the S24 Ultra has more recycled parts, including cobalt in its battery and rare earth elements in its speakers.
