Galaxy S25 Edge Hands-On: This Thin Phone Left a Deep Impression

At 5.8mm thick and 163 grams, this slim phone packs many of the features you’ll find on other S25 series devices. But the unique design is a breath of fresh air.

As I hold Samsung’s super-thin and light Galaxy S25 Edge, the first word that comes to mind is «airy.» My next thought is: If I were the S25 Plus, I’d be worried. 

In my early hands-on with the S25 Edge at a preview event in New York, I was struck by how much the new phone carries over from its S25 counterparts. It maintains the 200-megapixel wide camera from the S25 Ultra, the 6.7-inch display from the S25 Plus and the Snapdragon 8 Elite processor you’ll find across the other three S25 devices. But it does so within a sleek, 5.8mm titanium frame, clocking in at 163 grams. It feels like something I can throw in my bag or pocket and hardly notice.

In fact, the S25 Edge strikes me as exactly what a middle-of-the-line flagship phone should be: a fresh, elevated take on the baseline model, which pulls in premium features to justify its $1,100 price. The exciting design, Ultra-level wide camera and spacious display actually make this an enticing option for anyone who wants something a little out of the ordinary.

But that’s not to say there aren’t any compromises in store, the most notable being the battery; more on that later. 

Preorders for the Galaxy S25 Edge are open now, and the phone will arrive on May 30. It comes in three colors: silver, jet black and icy blue. 

What makes the S25 Edge stand out

The biggest question leading up to the release of the S25 Edge has been: Why would someone want a thinner phone anyway? After spending a little time with the device, I began to see the appeal. 

While the S25 Edge’s thickness may not be visually striking at first glance, getting your hands on the phone is a different story. Comparing how the S25 Edge’s 5.8mm, 163g frame feels to the S25 and S25 Plus, I registered just how much thinner and lighter it really is. For reference, the baseline S25 is 7.2mm thick and weighs 162g, but has a smaller 6.2-inch screen. The S25 Plus has the same 6.7-inch display as the Edge, but is 7.3mm thick and weighs 190g. It’s a noticeable difference. 

The moment of truth was applying some force to the phone to see if it gave at all. Impressively, it felt quite sturdy. (If not, I’d probably have gotten myself into some trouble with Samsung.) It touts a Corning Gorilla Glass Ceramic 2 display, along with a Gorilla Glass Victus 2 backing. My initial impression is that you shouldn’t have to worry about accidentally turning the S25 Edge into a foldable by keeping it in your back pocket, but that’s certainly something I’ll have to test in my review. The S25 Edge also maintains the same IP68 rating for dust and water resistance you’ll find on the other S25 series phones. 

The biggest trade-off, at least on paper, appears to be battery capacity. The Galaxy S25 Edge’s 3,900 mAh battery pales in comparison to what you’ll get on the baseline S25 (4,000 mAh) and the S25 Plus (4,900 mAh). Samsung isn’t sharing how many hours you’ll get out of the S25 Edge’s battery, other than stating it’ll last you all day. That’s something else I look forward to testing. The S25 Edge supports 25-watt wired charging and 15-watt wireless charging. 

With thinner phones, camera hardware can also be scaled back. But the S25 Edge boasts three cameras: a 200-megapixel wide, a 12-megapixel ultrawide and a 12-megapixel selfie camera. Megapixels aren’t everything, so I’m eager to see how that all translates into real-world photography. Samsung points to Galaxy AI for helping to boost camera quality and for powering photo editing features like Generative Edit. 

Like the S25 Plus, the S25 Edge has 12GB of RAM and 256GB and 512GB storage options. It’ll cost a little more than the S25 Plus, though: $1,100 for 256GB and $1,220 for 512GB. But it’s still priced lower than the top-of-the-line $1,300 S25 Ultra.   

You’ll find the same Galaxy AI features Samsung has been touting on the rest of its S25 phones, like Sketch to Image and Audio Eraser. Gemini features are also onboard, like Gemini Live and Circle to Search. 

On the edge of a new trend

The launch of the Galaxy S25 Edge comes amid a thin-phone phenomenon. Earlier this year, Oppo released its super-thin Find N5 foldable, which it calls the «world’s thinnest book-style foldable,» measuring just 8.93mm thick when closed and 4.21mm thick when opened. Apple is also rumored to be developing a thinner «Air» version of the iPhone 17. And at MWC 2025, phone maker Tecno showed off its Spark Slim phone concept, which measures 5.75mm thick and weighs just 146 grams, according to the company.

Depending on how consumers respond, the S25 Edge could be the phone to help kickstart the thin phone craze. If people don’t have to compromise too much when it comes to camera, storage and battery — three of the biggest considerations when buying a phone, according to a CNET survey — they could be inclined to pay up for a fresh form factor. After all, phones have become rather boring and predictable, apart from a handful of foldable options. The S25 Edge could be a breath of fresh air. 

I look forward to seeing how the S25 Edge holds up in the real world and whether it truly can maintain its edge (I had to do it).

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.
