The new Galaxy S24 which launched at Samsung’s Unpacked event on Wednesday.
At its Unpacked event on Wednesday, Samsung launched its Galaxy S24 and S24 Plus phones, which have the usual incremental upgrades over its predecessors. But its biggest leap is that it’s among the first smartphones to include generative AI capability — the same tech powering ChatGPT, Midjourney and other AI tools — directly on the device.
This story is part of Samsung Event, CNET’s collection of news, tips and advice around Samsung’s most popular products.
The on-device generative AI capabilities are made possible in part by Qualcomm’s Snapdragon 8 Gen 3 chipset, which also powers the Xiaomi 14 that beat Samsung to the punch for the first phone with the technology. Samsung calls its flavor of generative artificial intelligence Galaxy AI, which is split between some features powered by on-device AI and others relying on cloud-based AI.

Cloud-based AI isn’t as secure as on-device AI since it’s sending personal data off the phone, but does enable one of the coolest new features: Circle to Search, which lets you use your finger to circle an element on your screen to have AI look up what it is. It’s perfect for looking up that landmark in the photo your friend just sent you, and it works in whichever app you have open.
Other AI features include the ability to summarize the notes you’ve taken and make suggestions for changing the tone of messages when chatting with different people — formalizing your missives when talking to your boss or making them more casual when talking to friends, for instance. This was a feature showcased when Qualcomm unveiled the Snapdragon 8 Gen 3.
The generative AI extends to photo with generative editing, adjusting the tilt of the image, erasing reflections and shadows, and filling in the background when expanding an image (another trick Qualcomm showcased with the Snapdragon 8 Gen 3). Some of these features will get better as you take more photos and the system learns from them, Samsung says.
You can also choose to take a normally recorded video and produce a slow-motion version by generating additional frames in between.
Interestingly enough, all these generative AI features are on the Galaxy S24, S24 Plus and S24 Ultra and will also be coming to several of last year’s phones, including the Galaxy S23 series, Galaxy S23 Fan Edition, Z Fold 5 and Z Flip 5 (as well as the Tab S9 tablet) by the end of the first half of 2024. That suggests the tech in those phones — presumably including the Snapdragon 8 Gen 2 chip — can support generative AI, too.

The Galaxy S24 and S24 Plus both have larger batteries.
Aside from generative AI, the new Galaxy S24 series has other improvements on its predecessors. The standard S24 and S24 Plus are slightly larger (by 0.1 inches) than last year’s phones, with the S24 sporting a 6.2-inch display and the S24 Plus a 6.7-inch screen.
More importantly, the S24 Plus has a sharper screen with Quad HD resolution (roughly the same as the S24 Ultra’s resolution), up from Full HD Plus in the S23 Plus screen. The standard S24 retains Full HD Plus.
And the phones will be more usable outside on bright days, as all have increased their maximum brightness to 2,600 nits, up from 1,750 nits in the S23 series. By comparison, the new OnePlus 12, which will launch later this month in the US, has a 4,500-nit display.
Unlike the S24 Ultra and its new tougher titanium frame, the standard S24 and S24 Plus both still have aluminum frames and IP68 water- and dust-resistance ratings.
The cameras on the S24 and S24 Plus are largely the same as last year’s S23 and S23 Plus.
As for cameras, the standard S24 and S24 Plus are roughly unchanged from last year’s phones, with a 50-megapixel ultrawide camera, 12-megapixel ultrawide camera with 120-degree field of view, 10-megapixel 3x optical zoom camera and 12-megapixel front-facing camera.
There are other ways that more conventional AI will improve photos: Samsung says new advanced noise-reduction algorithms will distinguish between your movement and that of your subject, as well as reduce noise and improve object recognition. Low-light photography has also been improved.
In addition to enabling generative AI capabilities, the Snapdragon 8 Gen 3 offers better performance than its predecessor and improved ray tracing (introduced in last year’s S23 series). Samsung also improved the cooling system in all three phones, with a vapor chamber twice the size of those in the S23 series and two added layers of thermal interface material to better dissipate heat, as well as a final graphite sheet to assist the cooling.
Samsung simplified the storage and memory configurations of this year’s phones. The S24 is unchanged from its predecessor with 8GB of RAM and either 128GB or 256GB of storage. The S24 Plus has 12GB of RAM (up from 8GB in the S23 Plus) and either 256GB or 512GB of storage.
The S24 has a 4,000 mAh battery (up 100 mAh from the S23) and the S24 Plus has 4,900 mAh (a 200mAh increase on the S23 Plus). The phones have 5% better battery efficiency thanks to the Snapdragon 8 Gen 3, Samsung says.
The entire Galaxy S24 series now comes with seven years of software and security updates.
Samsung also increased the amount of recycled materials in the S24 series. While the S series has included recycled ocean plastic in the volume rocker and S Pen stylus holster of the Ultra phones since 2022, and recycled aluminum, glass and other types of recycled plastic in the S23 phones, this year’s handsets have up to 50% recycled cobalt in batteries in the S24 Ultra and Plus, as well as 100% recycled rare earth elements and 40% recycled steel in the speakers. The packaging also has 100% recycled paper material.
Samsung says it’s closer to eliminating single-use plastics and aims to do so as part of a series of goals by 2025. Other targets the company hopes to hit by then are incorporating recycled materials in all of its products, having zero standby power consumption in its chargers and achieving zero waste in landfills in its global operations. By 2030, the company intends to include recycled materials in every component of its mobile products.
Samsung has another big announcement which, in a roundabout way, also helps with sustainability: pledging seven years of Android and security updates. Supporting phones for that long will please owners who want to get the longest lifespan from their devices, which presumably means fewer old phones going to landfills. The pledge is on par with Google and almost as good as the sustainability-focused Fairphone, which offers eight years of updates.
For all these upgrades, the starting US prices for the S24 ($799) and S24 Plus ($999) are unchanged. But the added RAM, titanium frame and camera changes have resulted in a pricier S24 Ultra ($1,300) over last year’s S23 Ultra ($1,200). To soften the blow, Samsung is offering deals at launch for a storage upgrade at no extra cost.
All three S24 phones will come in four colors for retailers: yellow, violet, gray and black. Samsung’s website will additionally offer green, blue and orange hues.
