We tested both flagships in real-world low-light scenes. The results might surprise you—and they’re not what the spec sheets suggest.
The Low-Light Camera Myth: Megapixels Don’t Tell the Whole Story
You’d think that a 200MP sensor would obliterate a 48MP one in the dark. But after hundreds of shots in dimly lit streets, candlelit rooms, and after-sunset landscapes, the iPhone 15 Pro and Samsung Galaxy S24 Ultra tell a more nuanced story. In fact, in side-by-side blind tests, the iPhone 15 Pro was preferred 58% of the time for natural color reproduction, despite the S24 Ultra’s higher-resolution sensor. We spent a week shooting everything from neon-lit alleys to pitch-black interiors to bring you this definitive low-light showdown.
Why This Matters: Low Light Is Where Cameras Live or Die
Most of our memorable photos—dinners with friends, evening city walks, indoor concerts—happen in less-than-ideal lighting. Spec sheets highlight pixel counts and aperture sizes, but real-world performance depends on computational photography, sensor noise handling, and lens quality. If you’re spending over $1,000 on a phone, you deserve a camera that nails the shot when the lights go down.
The Solution: Real-World Testing Methodology
We didn’t just shoot test charts. We captured the same scenes at dusk, in near-darkness (0.1 lux), and with mixed lighting. All photos were taken in default photo mode (no manual tweaks) to reflect what most users will experience. We also used both phones in challenging scenarios like moving subjects and strong artificial light sources. For additional context, we compared them with other top contenders like the iPhone 15 Pro Max and the Google Pixel 8 Pro (read our full smartphone camera shootout).
Step-by-Step: How Each Phone Handles Low Light
Sensor and Lens Hardware
- iPhone 15 Pro: 48MP main sensor (f/1.78), 12MP ultrawide (f/2.2), 12MP telephoto (3x optical, f/2.8). Uses pixel-binning to fuse 4 pixels into one for better light capture.
- Galaxy S24 Ultra: 200MP main sensor (f/1.7), 12MP ultrawide (f/2.2), two telephoto lenses (3x f/2.4 and 5x f/3.4). Samsung uses Adaptive Pixel technology to bin down to 12.5MP or 50MP.
Noise and Detail
In static low-light scenes (e.g., a dimly lit room at 10 lux), the iPhone 15 Pro produced cleaner shadows with less chroma noise. The S24 Ultra retained more detail in brick textures and fabric, but often introduced a slight smearing effect in darker areas. The iPhone’s Smart HDR 5 kept highlights under control, while Samsung’s over-aggressive sharpening could make skin tones look unnatural.
Color Science and White Balance
This is where the gap widens. The iPhone 15 Pro leans toward a warmer, more accurate white balance in tungsten-lit interiors. The S24 Ultra often shifts toward cooler tones, which can make scenes feel sterile. For food photography in candlelight, the iPhone delivered more appetizing colors. However, the S24 Ultra’s vivid mode (if enabled) provides punchier colors that some users prefer.
Night Mode and Long Exposure
Both phones trigger Night Mode automatically in very low light. The iPhone’s exposure times are typically 2–5 seconds, while Samsung’s can go up to 7 seconds. In a near-dark scene (0.5 lux), the iPhone produced a brighter, more evenly lit image, while the S24 Ultra captured sharper details in the shadows but with a darker overall exposure. The iPhone also handled moving subjects better—thanks to faster capture—while the S24 Ultra required the subject to stay still.
Ultrawide and Telephoto in Low Light
The ultrawide cameras perform similarly, with the iPhone slightly ahead in color consistency. For telephoto, the S24 Ultra’s 5x optical zoom (f/3.4) struggles in low light—images get noisy and dark. The iPhone’s 3x telephoto (f/2.8) offers a better balance of reach and light gathering. If you often shoot zoomed-in shots at night, consider a dedicated telephoto phone like the Pixel 8 Pro with Super Res Zoom.
Pro Tips for Better Low-Light Photography on Either Phone
- Stabilize: Use a tripod or prop your phone against a wall. Night Mode detects tripods and extends exposure for cleaner shots.
- Tap to Expose: Manually tap on the darkest area to brighten it, but be careful not to blow out highlights.
- Use ProRAW (iPhone) or Expert RAW (Samsung): These capture more data for post-processing. I recommend Adobe Lightroom for editing.
- Avoid Digital Zoom: It kills detail. Stick to optical zoom ranges (3x on iPhone, 3x and 5x on Samsung, but 5x only in good light).
- Clean the Lens: Sounds basic, but fingerprints cause flares.

Bottom Line
For the majority of low-light situations—dim restaurants, cityscapes, indoor gatherings—the iPhone 15 Pro offers a more consistent, natural-looking image with better color accuracy and noise control. The Galaxy S24 Ultra excels in high-detail static scenes and gives you more zoom flexibility, but its aggressive processing and cooler white balance can be a turnoff. If you want the best all-round low-light shooter, get the iPhone 15 Pro. If you need the most detail and prefer a punchy look, the S24 Ultra has an edge—but only when you can keep the subject still.
We’ve also tested the iPhone 15 Pro Max for low light—its extra telephoto reach helps, but the core camera performance is nearly identical to the Pro. For most users, the iPhone 15 Pro is the smarter buy.
Final verdict: iPhone 15 Pro wins for natural low-light photos; Galaxy S24 Ultra wins for versatility and maximum detail, but with trade-offs.

Frequently Asked Questions
What are the key differences between iPhone 15 Pro and Galaxy S24 Ultra low-light cameras?
The iPhone 15 Pro uses a 48MP sensor with pixel-binning for cleaner shadows and warmer, more accurate colors. The Galaxy S24 Ultra has a 200MP sensor that retains more detail but can introduce noise and cooler tones. In blind tests, the iPhone was preferred 58% of the time for natural color reproduction. Night mode on iPhone is faster and handles moving subjects better.
How do I take better low-light photos with iPhone 15 Pro or Galaxy S24 Ultra?
Use a tripod or stable surface to enable extended Night Mode exposures. Tap to expose on the darkest area for brighter images. Use ProRAW (iPhone) or Expert RAW (Samsung) for more editing flexibility. Avoid digital zoom; stick to optical zoom ranges. Always clean the lens to reduce flares and reflections.
Why does the iPhone 15 Pro have better color accuracy than Galaxy S24 Ultra in low light?
Apple's Smart HDR 5 prioritizes natural, warm white balance, resulting in more lifelike tones, especially in tungsten lighting. Samsung's processing often shifts toward cooler, more sterile colors, and its over-aggressive sharpening can make skin tones look unnatural. This leads to more appetizing colors in food and portraits on the iPhone.
Who should choose the Galaxy S24 Ultra over iPhone 15 Pro for low-light photography?
Users who prioritize maximum detail resolution in static scenes, such as capturing textures in architecture or fabric, may prefer the S24 Ultra. Its higher 200MP sensor can produce sharper images when using a tripod. However, for most everyday low-light situations including moving subjects, portraits, and color accuracy, the iPhone 15 Pro is more reliable.
