Samsung's fresh new lineup of smartphones has officially arrived during the company's Unpacked event, with the Samsung Galaxy S24, S24 Plus, and S24 Ultra. But after going over all the striking features, you may be left wondering how these phones differ from the iPhone, arguably the most popular smartphone on the market, and how to choose the right one for your needs.

If you're trying to choose between the latest Samsung S series base model, theGalaxy S24 , and theiPhone 15 , you should know it may come down to individual preferences. Each smartphone has its strengths, which we will explore further to help you choose the right one for your priorities. But each one offers a different experience, leading to users going with personal preferences in the end, especially regarding the operating system. 

Specifications

You should buy the Samsung Galaxy S24 if...

1. You want generative AI in your hands

The new lineup of S24 smartphones includes several noteworthy artificial intelligence (AI) features. And it's no surprise; generative AI dominated headlines in 2023, and 2024 is promising to be a year where AI will truly reach the most uncommon places. Thus far, Samsung has the iPhone beat on the generative AI front.

While the iPhone 15 has few generative AI features, all three Samsung Galaxy S24, Plus, and Ultra smartphones have generative AI available in email, text, photos, voice memos, home, and more. Much like the Google Pixel phones, S24 users can move subjects within a photo and generate a part of an image to fill the vacated spot. A Galaxy S24 user could call someone that speaks a different language and use the AI-powered translation feature in real-time to have a conversation with an older relative from a different country, for example.

The Galaxy S24 also generates text for emails, transcribes and summarizes voice memos, and lets users circle an item on an image to perform a Google search. I can't speak for what Apple will launch this year, but the iPhone 15 is certainly not there yet.

2. A fast smartphone is a big deal to you

The iPhone 15 has an Apple A16 Bionic processor, while the Galaxy S24 features the Qualcomm Snapdragon 8 Gen 3 chip. While both are 4 nanometers (nm) processors, the S24 has 8GB of RAM compared to the iPhone 15's 6GB. 

These 4nm processors are advanced chips with better performance, faster processing speeds, smooth multitasking, and improved energy efficiency over previous models. But they also leverage the device's available RAM to perform at their peak. A 4nm processor combined with a higher RAM should maximize the system's capacity to handle more processes simultaneously and reduce strain on the processor. 

3. You want smoother scrolling during sunny days

The iPhone 15's refresh rate infamously tops out at a mere 60Hz unless you spring for the Pro or Pro Max models. The Samsung Galaxy S24, in turn, features a variable refresh rate of up to 120Hz to match the content displayed on the device. 

Also: Samsung's new Galaxy S24 beats the iPhone 15 Pro in one very meaningful way

You don't have to be a hardcore gamer to appreciate a variable refresh rate -- the feature also makes for smoother video playback scrolling and, since the refresh rate is dynamic and is automatically lowered when static content is being displayed, like a photo, the S24 conserves battery and processing power. 

The Galaxy S24 also has a peak brightness of 2,600 nits, a big difference compared to the iPhone 15's 1,000 nits. This makes it so your S24's screen remains legible when you're out in bright lights, like outside during sunny weather.

You should buy the iPhone 15 if...

1. You'd prefer a better resolution

The iPhone 15's display is slightly smaller than the Galaxy S24's, about 0.1 inches smaller, yet its screen resolution and pixel density are higher, promising a more realistic and crisp image. If you can get past the lower refresh rate and peak brightness in favor of a cleaner image, then the iPhone 15 is far from a bad choice.

2. You enjoy the Apple ecosystem

Many iPhone fans prefer to stick with the Apple brand because they like being immersed in its ecosystem. The ease with which users can switch from one device to another, knowing they can always rely on them with few snags or bugs, has been enough to convince many users to continue buying iPhones.

That being said, Apple runs things like a walled garden, selling exclusivity for frivolous features like blue message bubbles and devices that all look and act the same. But some Apple fans find comfort in the expected, knowing that the next brand new iPhone they get will operate much like their previous one and that it will work seamlessly with their iPad, AirPods, and Apple Watch. 

If you're coming from an iPhone and considering switching to a Galaxy S24, I can only recommend you think hard about what you enjoy from the Apple ecosystem -- you can't use an Apple Watch with a Samsung phone, after all. But if you consider it and find yourself still curious and open to leaving behind the predictable iPhone world, the Samsung Galaxy S24 is a great alternative. 

3. You think pink

Your smartphone's color may not be a thing you give much thought to, but many users do care what color their phone is -- particularly the younger crowd, who are the most common users of entry-level phones like the iPhone 15 and Galaxy S24. The iPhone 15 is available in pink, black, blue, green, and yellow, while the Galaxy S24 comes in Onyx Black, Marble Grey, Cobalt Violet, and Amber Yellow.
