Infinix HOT 60 Pro+ – 5.95 mm

The Infinix HOT 60 Pro+ features a jaw-dropping 5.95mm slim profile, weighing just 155g—and somehow, it still packs a massive 5160mAh battery inside.

Samsung Galaxy S25 Edge – 5.8 mm

Samsung launched its slimmest flagship yet in May 2025. Featuring a 6.7-inch AMOLED display, 200 MP camera, and Snapdragon 8 Elite chipset, the S25 Edge packs premium features into a titanium body just 5.8 mm thick. It’s a compelling choice for those putting design and portability first.

TECNO Spark Slim – 5.75 mm

Unveiled at MWC 2025, the Spark Slim concept showcases what engineering can achieve: 5.75 mm thin, 146 g, a 5,200 mAh battery, and a 6.78-inch AMOLED display.

Though not yet available for sale, it sets a new benchmark for sleek design without sacrificing battery life.

Apple iPhone 17 Air (Rumored) – ~5.5 mm

Expected in September 2025, leaks suggest the iPhone 17 Air will be Apple’s thinnest iPhone ever, measuring around 5.5 mm.

Despite its slim build, it could include a 6.6″ OLED display, A19 chip, and an optimized battery system, thanks to new silicon-anode tech .

Foldables: Xiaomi, Oppo & Honor

In early 2025, OPPO made history with the Find N5, officially crowned the world’s thinnest book-style foldable phone .

This sleek device not only sets a record—it redefines the future of smartphone design. 8.93 mm when folded, rivalling the thickness of a credit card. Only 4.21 mm thick when unfolded, making it marginally slimmer than any non-foldable device .

Thinness isn’t limited to traditional phones—ultra-slim foldables are making waves too:

• Xiaomi Mix Fold 4 – 4.6 mm unfolded
• Oppo Find N5 – 4.2 mm unfolded
• Honor Magic V3 – 4.4 mm unfolded

These devices blend bigger full-screen experiences with featherweight folded forms, redefining portability.

Which of thesee phones are you buying? Tell us in the comment session

And here we are again, caught in the annual ritual where smartphones drop harder than oil prices, and consumers must choose between two very different kinds of obsession, iPhone 16 Pro Max and Samsung S25 Edge.

If phones were human beings, the iPhone 16 Pro Max would be a well-dressed executive who insists on doing everything himself, efficient, polished, slightly uptight; the Galaxy S25 Edge would be the fashion-forward genius who can host a dinner party while live-translating Shakespeare into code. 

Both command attention. Both are brilliant. But they speak very different languages.

Here’s my take after combing through both devices.

Design and Build: Slim vs Serious

Let’s start with what you’ll feel in your hand. The S25 Edge is slim, just 5.8mm thin and 163g light. It’s basically the Kate Moss of smartphones, all titanium bones, curves, and Gorilla Glass Ceramic. 

Samsung stripped it down without stripping away power, and that alone deserves credit. It’s a fine, strong, and truly pocket-friendly phone.

The iPhone 16 Pro Max, on the other hand, is built at 6.9 inches with a new titanium frame, it’s Apple’s most refined industrial design ever, sleek but weighty. It’s not trying to be slim, but iconic. And in typical Apple fashion, it is mostly excellent.

Verdict: The S25 Edge is the better looker if you’re after elegance; the iPhone is a fortress with flair.

Display and Visual: Quality vs Quantity

Samsung gives you a 6.7-inch QHD+ Dynamic AMOLED 2X screen. It’s rich, sharp, and adaptive with 120Hz refresh rate. Add in mDNIe visual enhancement, and you’re staring at a device with a highly captivating display that fully draws you in.

And Apple’s? The 6.9-inch Super Retina XDR display with ProMotion tech and always-on functionality. Bigger, vivid, and paired with the thinnest borders ever on an iPhone.

My pick: Samsung wins on pure eye comfort and smart display scaling. But if you’re a fan of cinematic colours and smoother animations, Apple has a slight edge with its A18 Pro chip driving visuals like a film editor on espresso.

Performance: Brains Behind the Beauty

Apple’s A18 Pro chip is no joke. Built on second-gen 3nm tech, it tears through tasks—4K 120fps video, real-time transcriptions, even gaming at console levels. The iPhone 16 Pro Max is a performance giant, plain and simple.

Samsung’s Snapdragon 8 Elite for Galaxy isn’t far behind. It handles gaming, editing, and AI processing smoothly, especially with its custom vapour cooling system. If you multitask hard, maybe Zoom, video editing, and AI sketching all at once, it holds steady.

Reality check: Both will do everything you throw at them. But Apple’s chip, paired with iOS 18 and native hardware-software harmony, makes the experience feel more seamless, more instant.

Cameras: Detail vs Drama

Samsung built a 200MP wide camera into a frame slimmer than most wallets. Add a 12MP ultra-wide and a 12MP selfie cam, and you’ve got a photography giant house. Low light? Sorted. Macro? Effortless. Video tools like Audio Eraser and Drawing Assist are genuinely useful for creators.

Apple’s camera system is… surgical. The 48MP Fusion camera might sound unassuming by comparison, but quality trumps quantity here. Paired with a 5x telephoto lens and advanced image signal processing, the results are cinematic. Add real-time editing, Photographic Styles, and spatial video, and it’s like holding a film studio.

Truth: Samsung Galaxy S25 Edge gives you firepower, Apple iPhone 16 Pro Max gives you finesse. Pick your battle.

Intelligence and Software Experience: Who Thinks Smarter?

Both brands have gone all-in on user-aware functionality.

Apple’s “Apple Intelligence” reads like a privacy-first personal assistant that remembers context, rewrites emails, summarises alerts, and answers naturally via a smarter Siri. Most of it works on-device or through secure Private Cloud Compute.

Samsung answers with Galaxy AI and One UI 7 running on Android 15. It’s a bit louder, more experimental, like Gemini Live, which lets you share your screen in real time during chats. Contextual automation adapts to your daily patterns.

Who’s smarter? Depends. Apple is intuitive, private, and clean. Samsung is versatile, social, and forward-thinking.

Battery and Charging: Endurance vs Ecosystem

iPhone 16 Pro Max comes with its biggest battery yet, finely optimised through iOS 18. No exact numbers, but it comfortably outlasts most of the competition.

Samsung’s 3,900mAh battery feels like a compromise for the thin design. It charges 55% in 30 minutes and supports wireless options, including PowerShare. Practical.

Verdict: Depends on your usage and battery protection.

Price and Availability

• iPhone 16 Pro Max: Starts at $1,199 (₦1.9m)
• Samsung S25 Edge: Starts at $1,099 (₦1.7m)

Bearing in mind that rates fluctuate.

Which Should You Buy?

• Choose iPhone 16 Pro Max if you want the absolute best in performance, professional-grade camera finesse, and a deeply integrated software-hardware ecosystem. You’ll feel its weight, but also its worth.
• Choose Samsung S25 Edge if you prefer an ultra-portable design, cutting-edge photography tech, and a more open, adaptable software experience. It’s modern, awesome, and ready to evolve.

Me? I’d take the iPhone for the discipline, the Samsung for the charm, and probably wish I could merge the two. But alas, the life of smartphones still comes in separate boxes.

At just 5.8mm thick and 163 grams in weight, the S25 Edge shaves off nearly a third of the bulk seen in the Ultra model, and it still manages to house a top-tier 200MP camera, a titanium frame, and Galaxy’s most advanced on-device features to date. 

It goes on sale in the UK and US from 30th May, with a retail price starting at £1,099 (₦2.4m) for the 256GB model and £1,199 for the 512GB version.

We’ve taken a deep look into what this device offers, and it’s beyond good looks.

Ultra-Slim, Still Strong

Samsung hasn’t cut corners with this slimmed-down design. The titanium chassis and Corning Gorilla Glass Ceramic 2 give the phone structural integrity while keeping it light. 

Its smooth curved edges and minimal thickness make it feel more like a fashion accessory than a tech gadget, but it’s built to last.

The weight-to-power ratio is commendable. At 163g, the S25 Edge feels almost featherweight in hand, yet it carries the same flagship-grade internals found in the beefier S25 Ultra.

Camera System

Here’s where the Galaxy S25 Edge pulls ahead of anything this thin: the camera. It retains Samsung’s best-in-class 200MP wide sensor with 2x optical-quality zoom, paired with a 12MP ultra-wide lens with autofocus for macro shots, and a 12MP front camera.

Night photography gets a serious upgrade, with Samsung claiming over 44% brightness improvement in low-light scenarios. Add in pro-grade image enhancement from the Galaxy ProVisual Engine and you’ve got a camera system that handles everything from portraits to plants without missing detail.

Users still get AI-assisted tools like Audio Eraser and Drawing Assist, features previously seen on the S25 series, now brought into a much slimmer form.

Performance 

The S25 Edge is powered by the Snapdragon 8 Elite for Galaxy, delivering AI-enhanced processing and fast performance across all use cases, from streaming and gaming to camera processing and productivity tasks.

Samsung has reworked the internal cooling system to ensure stable performance. A broader but thinner vapor chamber sits under the hood, making sure the device stays cool under pressure.

ProScaler tech brings a 43% improvement in display image scaling, while Samsung’s mobile Digital Natural Image engine (mDNIe) enhances visual output with noticeable clarity.

Smart Features That Learn With You

Running Android 15 and One UI 7, the Galaxy S25 Edge is deeply integrated with Galaxy AI, Samsung’s focus on intelligent, user-aware functionality. The AI experience is everywhere: from editing tools to smart reminders and contextual routines that adapt to your location and habits.

One of the unique integrations is Gemini Live, which lets users share real-world or on-screen visuals in real time while chatting. It’s a clever step toward making AI feel like part of the user interface rather than just a behind-the-scenes processor.

Annika Bizon, mobile experience VP of Product and Marketing at Samsung UK & Ireland, said: “Galaxy S25 Edge redefines smartphone design, with no compromise on performance. It’s our slimmest S Series device yet, created with style and strength in mind. Featuring an iconic Galaxy AI-enabled camera, it opens up a world of creativity in a light, elegant form factor for customers wanting stylish design and the best features Galaxy has to offer.”

Battery Life and Charging

Battery capacity is rated at 3,900mAh, with a 55% charge achievable in around 30 minutes using a 25W adapter (sold separately). Fast wireless charging and Wireless PowerShare are also supported, including compatibility with Samsung’s existing wearables and select smartphones.

Water Resistance, Colours, and Connectivity

The Galaxy S25 Edge is IP68-rated, meaning it can survive submersion in up to 1.5m of freshwater for up to 30 minutes, though it’s not built for beach or pool use.

Connectivity options are forward-facing: 5G, LTE, Wi-Fi 7, Bluetooth 5.4, and full Samsung ecosystem support.

It comes in three colours—Titanium Silver, Titanium Jetblack, and Titanium Icyblue.
