The Samsung S25 Edge’s Camera Is Good Enough to Rival the Ultra

If you ever wondered whether people buy phones for the cameras, take a look at the Samsung S25 Edge.

Creating a super thin phone is a prime opportunity for compromise. If the goal is to reduce the profile of an already slim device, a bulky camera would naturally be one of the first things to toss overboard.

And yet the Samsung Galaxy S25 Edge, now officially announced, includes a surprising 200 megapixel (MP) f/1.7 wide-angle camera that shares the same specs as the one in Samsung’s Galaxy S25 Ultra. In fact, you could argue that the 200MP camera alone justifies the Edge’s $1,100 price, with the latest versions of Android and Gemini as added bonuses in a thin and light body. To get that same camera resolution on the S25 Ultra, you’d need to fork over $1,300 or more.

So why did Samsung choose to include a top-tier feature in a phone that sits in the middle of its S25 lineup?

Most phones are cameras with phone features

The difference between phones in the same lineup often comes down what each model adds over the others.

The Galaxy S25 is a thoroughly capable phone that (to cherry pick specs) runs the latest software on a Snapdragon 8 Elite processor, packs a 4,000 mAh battery, has a 6.2-inch display and features the following array of cameras: 50MP wide-angle, 12MP ultra-wide, 10MP 3x telephoto and 12MP front camera. For 256GB of storage, it costs $860. The 128GB base model starts at $800, but I’m using the 256GB version to keep the storage consistent across all our examples.

The Galaxy S25 Plus shares all of those same features in a larger package, with a 6.7-inch screen and — due to its roomier case — a larger 4,900 mAh battery. For that you’ll pay an extra $140 more than the S25 to get the 256GB config at $1,000.

Then you jump $300 for the $1,300 Galaxy S25 Ultra, which boasts several specs such as the aforementioned 200MP main camera, a 50MP ultra-wide camera, a second 50MP telephoto camera with 5x optical zoom, a slightly larger 6.9-inch screen and a 5,000 mAh battery.

So where does the Galaxy S25 Edge slot into the lineup? For $1,100, it has the same 6.7-inch screen as the S25 Plus with an additional layer of protection (it’s covered with Corning’s Gorilla Glass Ceramic 2), the same Snapdragon 8 Elite processor, a smaller 3,900 mAh battery (to be expected in a thinner case) — and that 200MP wide camera.

Although the camera shares the same specs as the one in the S25 Ultra, it’s not yet clear whether it’s the same hardware. In Samsung’s event video officially announcing the S25 Edge, the company described how it redesigned the camera housing to fit the 200MP camera. I’m assuming it’s the same core hardware, just repackaged to fit a smaller form factor, but a direct photo comparison will be the real test.

Thin isn’t enough on its own

By the name alone, the primary appeal of the S25 Edge is its thin design. The company’s introductory video is full of schematics and computer-generated animations of all the phone’s components slotting together into its svelte body. And thinness does have value — just look at Apple’s obsession with making everything thin and light over the years, including its own rumored iPhone 17 Air.

But thinness as a feature isn’t additive enough (to make the obvious joke, it’s literally reductive). Samsung could have easily included the 50MP wide camera used on the S25 and S25 Plus and focused solely on the phone’s design to set it apart. By including the top-end 200MP camera from the series’ most expensive and premium phone, though, it hits a sweet spot where a customer thinks, «I’m getting a super thin version of the S25 but with the camera of the $1,300 S25 Ultra.»

Decent zoom is still possible, even without a telephoto camera

The other thing that sets the S25 Edge apart is the fact that it does not include a dedicated telephoto camera. Every other S25 model includes at least one telephoto camera to zoom in on distant subjects.

That extra reach is usually the dividing line between «consumer» and «pro» models. For example, the Pixel 9 and 9A and iPhone 16 and 16E all include wide-angle and ultra-wide cameras, but no telephoto. People regularly zoom in when taking photos, so Google and Apple pitch higher-quality optical zoom as a premium feature at the higher price levels of the pro models.

But by including the 200MP camera on the S25 Edge, Samsung can still claim a 2x «optical quality» zoom. Technically that’s a crop into the middle of the sensor, but the high megapixel count means there’s still plenty of resolution to get quality images. You can still zoom at farther ranges, but you’re leaning heavily on image processing to enhance the digitally-zoomed image.

(An important aside about resolution: Keep in mind you’re not always capturing images at 200MP resolution. The default resolution is a pixel-binned 12MP, where the camera groups pixels together on the sensor to act as a larger pixel that gathers more light. So at that resolution, the S25 Edge is likely using AI upscaling to zoom. But at the 50MP and 200MP resolution settings, the 2x zoom is more likely to be a straight crop from what the sensor is recording.)

This also reinforces the fact that phone photography is increasingly buttressed by real-time, AI-supported image processing. Shooting at the full 200MP resolution involves considerable processing to enhance details recorded by such a physically small image sensor. Even with pro phones, I regularly see people use pinch-to-zoom instead of switching among the better quality preset optical options. (Android Authority surveyed its readers and found that about 27% of respondents zoom freely versus sticking to preset zoom levels.)

Will customers specifically buy the S25 Edge because of its camera features? Not entirely, but touting the 200MP camera prominently along with the new thin design gives them extra incentive to choose it.

We’re looking forward to testing the S25 Edge’s camera to see how well it performs. In the meantime, be sure to check out the photos that CNET Managing Editor Patrick Holland made for his Galaxy S25 Ultra review, as well as Andrew Lanxon’s images pitting the S25 Ultra head-to-head against the iPhone 16 Pro.

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.
