Camera Champs Galaxy S25 Ultra and iPhone 16 Pro: Is It Even a Toss-Up Between the Two?

Both phones feature state of the art mobile cameras, but which is better? Let’s take a photowalk and find out.

Yes, you can justify getting a top-end phone for its camera quality alone, but which one is best? Until we see what the iPhone 17 Pro photo system might bring (I have some suggestions), I pitted the iPhone 16 Pro against the Samsung Galaxy S25 Ultra, which are both capable of capturing stunning photos. How do these mobile titans compare?

To find out, I shot hundreds of photos using both phones in a variety of conditions to see which takes the best images. What’s «best» often comes down to personal perspective. So though I’ll share my take on each test as a professional photographer — including why I prefer one over the other — you might find you prefer the opposite. Have a look through the range of examples below and see if you come to a different conclusion.

All images shown have been taken using each phone’s default camera mode and default settings, unless otherwise noted. Images from the Galaxy S25 have been uploaded as taken, but the iPhone’s images have had to be converted through Adobe Lightroom, because our publishing platform doesn’t support Apple’s default HEIF image format. This process doesn’t affect the image in any way.

Ready? Let’s dive in.

Starting out with an easy outdoor scene. Both phones have done a great job capturing an even exposure here and both images are packed with detail. It’s difficult to choose between them, but the iPhone has the edge for me as it’s achieved a slightly warmer image with more natural-looking tones. The S25 Ultra’s image looks too saturated, especially in the blue sky, which I find quite distracting.

It’s much the same story when we switch to the ultrawide lenses on both phones. I prefer the warmer tones in the iPhone’s shot, which makes the S25 Ultra’s look quite cold by comparison. I also prefer the lighter shadows on the iPhone’s image, making it an easy win for the iPhone here. Notably, both phones are doing a good job of compensating for the ultrawide lenses at the edges (a function turned on by default on both phones); the railing remains straight in each shot and not curving as you’d typically see using a lens this wide.

There’s almost no difference between these two outdoor scenes. The blossom looks crisp on both images, with excellent overall exposure. The iPhone’s image is again slightly warmer in tone but it’s negligible.

The Galaxy S25 takes an easy win with this image of bluebells. The colors are much more vibrant, especially in the greens on the blades of grass, which look quite washed out on the iPhone’s image. It actually looks like the S25’s camera lens is slightly polarized to reduce reflections and increase saturation, but I don’t know if that’s the case. Either way, Samsung takes the win here.

At 5x zoom things get worse for the iPhone. Despite the bluebells being reasonably far away, the phone seemed unable to achieve a sharp focus on the flowers. The S25 Ultra, meanwhile, managed to achieve a sharp image with richer colors.

I prefer the iPhone’s image here though. It’s brighter and the warmer colors on the bricks on the surrounding buildings look much more true to life.

The iPhone’s image is again brighter here and I prefer its colors too. The Galaxy S25 Ultra does have the edge in fine detail, though. You really need to zoom in to see it but the tiny lines on the building are slightly sharper on the S25.

The S25 Ultra does have a physical advantage over the iPhone with its 10x optical zoom lens, which allows it to zoom in even further while still maintaining a pin-sharp image.

You can still digitally zoom in with the iPhone to 10x, and the results aren’t bad. I prefer the colors of the S25 Ultra’s shot here, but the difference in detail isn’t that noticeable.

Zooming in close to see the fine details, the S25 Ultra’s optical zoom image definitely has a bit more clarity but the digital upscaling on the iPhone’s shot has done a great job here, as the difference isn’t immense.

iPhone 16 Pro vs. Galaxy S25 Ultra: Night modes compared

At first glance, the only real difference between the iPhone’s 5x shot and the S25 Ultra’s 5x shot is the color balance. And honestly, I don’t have a preference between the warmer tone of the iPhone or the more magenta bias of the S25.

However, when you zoom in close to the details, the iPhone has produced a sharper image here, with an odd sort of digital blurring around the lamp post in the S25 Ultra’s image. So sometimes the S25 Ultra’s zoom is sharper, other times it’s the iPhone’s. I’m glad they’re making this easy for me.

Again, the only real difference here is in the color balance and I don’t really know which I prefer. The exposure, noise levels and amount of detail are practically identical.

Things changed when I switched to the ultrawide lenses, though. The S25 Ultra’s shot is definitely brighter, capturing more detail in the cobblestones in the foreground and in the buildings in the distance. The iPhone’s image is much darker overall.

Just to confuse things further, the iPhone’s nighttime image with its ultrawide lens is noticeably brighter than the S25 Ultra’s in this example that I shot in the Arctic. I actually had to double-check the image metadata to make sure I hadn’t mixed these up, but I haven’t. The iPhone’s image has captured more light information here and produced more detail on the ice door to the right.

The iPhone’s nighttime image is again slightly brighter here but it’s also kept the bright highlights on the pub sign under control. On the S25 Ultra’s image, those highlights are almost lost to pure white but the lovely green and yellow tones have been retained in the iPhone’s image. The colors overall are noticeably warmer on the iPhone’s shot, however, which may not be to your taste. Here, I think they work well.

But in this example, the iPhone has produced a weirdly warm-looking image that I really don’t like. Those warm colors were not present at the time of capture and it doesn’t work for the scene, especially not with such strong orange tones in the sky. The S25 Ultra’s image is much more balanced overall and it’s a slightly sharper image too. It’s a very easy win for Samsung here.

Things don’t improve for the iPhone when using the ultra-wide lens. Its image is again plagued by overly warm tones, while the S25 Ultra’s shot is both more color-accurate and brighter.

iPhone 16 Pro vs. Galaxy S25 Ultra: Which takes better selfies?

While the Galaxy S25 Ultra’s selfie is slightly brighter, I don’t like what it’s done with the colors. My face has been made a weird shade of orange and my denim jacket is a much deeper blue than it really is. The skin tones on the iPhone’s shot are much more accurate, and its shot is sharper as well.

Both phones have a wider-angle mode for the selfie camera, although the iPhone’s seems to be a lot wider. That’s definitely worth keeping in mind if you frequently like to cram lots of friends into your group pics. You could probably squeeze at least one or two extra friends in if you used the iPhone, or have to decide who you like least and leave them out of frame if you used the S25 Ultra. Otherwise, the image differences are the same as before.

iPhone 16 Pro Vs Galaxy S25 Ultra: Which camera is better?

I’ve written many of these comparison pieces on various generations of phones in my 14 years at CNET and I don’t remember having done one that’s felt this close. The problem is that neither phone excels consistently in one area; the iPhone 16 Pro’s ultra-wide shots aren’t as bright as the S25 Ultra’s, except on those occasions when they actually are, confusingly. I’ve taken many more images not included here that both support some of my conclusions and argue against them. Go figure.

But there are some takeaways I can give with confidence. Generally speaking, the iPhone’s colors are more natural than the S25 Ultra’s, which can sometimes look overly saturated. This has been the case with almost every Samsung phone since the company started putting cameras in them and it’s still the case today. Those looking for a more natural base image to apply your own filters and effects over will be better suited with the iPhone 16 Pro.

But that’s less the case at night, when the iPhone more consistently delivers warmer tones that look less natural than the S25 Ultra’s. So, if night photography is important to you, the S25 Ultra may be the better option. Overall, its night mode images from all lenses were brighter and sharper.

Sure, the S25 Ultra has the extended zoom range, but you’d really need to know you’ll make the most of a 10x zoom to justify picking one over the other. Personally, I find the 5x zoom level a perfect sweet spot, and here the phones are pretty much on par. And on those rare occasions you may want to push things further, the iPhone’s digital zoom can still deliver sharp results.

There are other things for photographers to consider too: Apple’s ProRaw is superb and while the company’s Photographic Styles can be good for adding a creative look to your images, Samsung’s new tool for mimicking the color grade from example photos you feed it works surprisingly well — I actually think I might get more use out of that overall. I haven’t even gone into video quality either, which is a whole other article, especially when you consider both phones shoot Log video, although only the iPhone uses ProRes.

Deciding between the phones based solely on the cameras is nigh on impossible. Which one you should get will instead come down to the bigger question of iOS versus Android; which platform you’re already using and which one will work best with other pieces of tech in your life. But for simple picture quality, you may as well toss a coin.

Kohler Wants to Put a Tiny Camera in Your Toilet and Analyze the Contents

The company’s new Dekoda toilet accessory is like a little bathroom detective.

Some smart litter boxes can monitor our pets’ habits and health, so having a camera in our human toilet bowls seems inevitable. That’s just what kitchen and bathroom fixture company Kohler has done for its new health and wellness brand, Kohler Health.

The $599 Dekoda clamps over the rim like a toilet bowl cleaner, pointing an optical sensor at your excretions and secretions. It then analyzes the images to detect any blood and reviews your gut health and hydration status. Depending on the plan you choose, the subscription fee is between $70 and $156 per year.

At toilet time, you sign in via a fingerprint sensor so that the device knows who’s using the facilities. (Please wash your hands before signing out or tracking your progress.) Then, check in with the app for the day’s analysis and trends over time.

Wait until you’re off the pot, though, before you start doomscrolling your health. The device has a removable, rechargeable battery and uses a USB connection.

Kohler says it secures your data via the aforementioned fingerprint scanner and end-to-end encryption, and notes that the camera uses «discreet optics,» looking only at the results, not your body parts.

«Dekoda’s sensors see down into your toilet and nowhere else,» the company says.

Kohler warns that the technology doesn’t work very well with dark toilet colors, which makes sense. I’m sure there could be an upsell model with a light on it. Maybe the company could add an olfactory sensor, since smell reveals a lot about your gut health too. It could track «session» length or buildup under the rim to alert whoever has responsibility to clean it.

Kohler must have been straining to find appropriate lifestyle photos to include with the publicity materials. Many of the images are hilarious, featuring fit-looking men and women drinking water and staring off into space contemplatively — probably thinking about gas.

Does Charging Your Phone Overnight Damage the Battery? We Asked the Experts

Modern smartphones are protected against overcharging, but heat and use habits can still degrade your battery over time.

Plugging your phone in before you head to bed might seem like second nature. That way by the time your alarms go off in the morning, your phone has a full charge and is ready to help you conquer your day. However, over time, your battery will start to degrade. So is keeping your phone plugged in overnight doing damage to the battery?

The short answer is no. Keeping your phone plugged in all the time won’t ruin your battery. Modern smartphones are built with smart charging systems that cut off or taper power once they’re full, preventing the kind of «overcharging damage» that was common in older devices. So if you’re leaving your iPhone or Android on the charger overnight, you can relax.

That said, «won’t ruin your battery» doesn’t mean it has no effect. Batteries naturally degrade with age and use, and how you charge plays a role in how fast that happens. Keeping a phone perpetually at 100% can add extra stress on the battery, especially when paired with heat, which is the real enemy of longevity.

Understanding when this matters (and when it doesn’t) can help you make small changes to extend your phone’s lifespan.

The science behind battery wear

Battery health isn’t just about how many times you charge your phone. It’s about how it manages voltage, temperature and maintenance. Lithium-ion batteries age fastest when they’re exposed to extreme levels: 0% and 100%.

Keeping them near full charge for long stretches puts additional voltage stress on the cathode and electrolyte. That’s why many devices use «trickle charging» or temporarily pause at 100%, topping up only when needed.

Still, the biggest threat isn’t overcharging — it’s heat. When your phone is plugged in and running demanding apps, it produces heat that accelerates chemical wear inside the battery. If you’re gaming, streaming or charging on a hot day, that extra warmth does far more harm than leaving the cable plugged in overnight.

Apple’s take

Apple’s battery guide describes lithium-ion batteries as «consumable components» that naturally lose capacity over time. To slow that decline, iPhones use Optimized Battery Charging, which learns your daily routine and pauses charging at about 80% until just before you typically unplug, reducing time spent at high voltage.

Apple also advises keeping devices between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and removing certain cases while charging to improve heat dissipation. You can read more on Apple’s official battery support page.

What Samsung (and other Android makers) do

Samsung offers a similar feature called Battery Protect, found in One UI’s battery and device care settings. When enabled, it caps charging at 85%, which helps reduce stress during long charging sessions.

Other Android makers like Google, OnePlus and Xiaomi include comparable options — often called Adaptive Charging, Optimized Charging or Battery Care — that dynamically slow power delivery or limit charge based on your habits. These systems make it safe to leave your phone plugged in for extended periods without fear of overcharging.

When constant charging can hurt

Even with these safeguards, some conditions can accelerate battery wear. As mentioned before, the most common culprit is high temperature. Even for a short period of time, leaving your phone charging in direct sunlight, in a car or under a pillow can push temperatures into unsafe zones.

Heavy use while charging, like gaming or 4K video editing, can also cause temperature spikes that degrade the battery faster. And cheap, uncertified cables or adapters may deliver unstable current that stresses cells. If your battery is already several years old, it’s naturally more sensitive to this kind of strain.

How to charge smarter

You don’t need to overhaul your habits but a few tweaks can help your battery age gracefully.

Start by turning on your phone’s built-in optimization tools: Optimized Battery Charging on iPhones, Battery Protect on Samsung devices and Adaptive Charging on Google Pixels. These systems learn your routine and adjust charging speed so your phone isn’t sitting at 100% all night.

Keep your phone cool while charging. According to Apple, phone batteries perform best between 62 and 72 degrees Fahrenheit (16 to 22 degrees Celsius). If your phone feels hot, remove its case or move it to a better-ventilated or shaded spot. Avoid tossing it under a pillow or too close to other electronics, like your laptop, and skip wireless chargers that trap heat overnight.

Use quality chargers and cables from your phone’s manufacturer or trusted brands. Those cheap «fast-charge» kits you find online often deliver inconsistent current, which can cause long-term issues.

Finally, don’t obsess over topping off. It’s perfectly fine to plug in your phone during the day for short bursts. Lithium-ion batteries actually prefer frequent, shallow charges rather than deep, full cycles. You don’t need to keep it between 20% and 80% all the time, but just avoid extremes when possible.

The bottom line

Keeping your phone plugged in overnight or on your desk all day won’t destroy its battery. That’s a leftover myth from a different era of tech. Modern phones are smart enough to protect themselves, and features like Optimized Battery Charging or Battery Protect do most of the heavy lifting for you.

Still, no battery lasts forever. The best way to slow the inevitable is to manage heat, use quality chargers and let your phone’s software do its job. Think of it less as «babying» your battery and more as charging with intention. A few mindful habits today can keep your phone running strong for years.
