TECNO has officially launched its groundbreaking TECNO Slim series at IFA 2025, setting a new milestone in smartphone design and performance. The lineup includes the TECNO SPARK Slim (4G) with a 5.93mm profile and the TECNO POVA Slim (5G) at 5.95mm, both ranking among the world’s thinnest smartphones with 3D-curved AMOLED displays. Despite their record-breaking slimness, the models pack a 5160mAh battery with 45W fast charging, along with military-grade durability certification, balancing elegance with resilience.

Engineering Breakthrough in Structural Innovation

At under 6mm, TECNO Slim pushes smartphone miniaturization further than ever before. The company has re-engineered eight core modules, including the battery, speaker, SIM slot, and charging connector, achieving unmatched compactness. The device also introduces a 0.45mm single-tab Type-C connector inspired by foldables, reducing bulk. Combined with TECNO’s Honeycomb stacking technology, the phone gains 12% more internal space efficiency, proving that ultra-thin does not mean underpowered.

Strength Meets Slimness

To maintain strength within its ultra-slim body, TECNO uses a 0.36mm aerospace-grade fiberglass back cover that is 300% stronger and 200% tougher than standard composite plates. On the front, Corning Gorilla Glass 7i adds protection against scratches and drops, while IP64-rated water and dust resistance further enhances reliability. Certified Military-Grade Shock Resistant, the TECNO Slim offers toughness within a feather-light form.

Power and Endurance in a Slim Package

Battery life, often a weak point in slim devices, has been revolutionized with TECNO Slim. The 5160mAh high-density lithium cobalt oxide battery achieves extended longevity while staying just 4.04mm thick. Even after 2,000 charge cycles, it retains 80% capacity, delivering over five years of reliable use. Coupled with 45W fast charging, users enjoy up to 28 hours of usage on a single charge. An advanced cooling system with vapor chamber and graphite layers ensures smooth performance under heavy loads.

Advanced Performance and Immersive Displays

The TECNO Slim offers distinct performance solutions: the 4G version with Helio G200 and the 5G model powered by MediaTek Dimensity 6400 5G+, ensuring efficiency and next-gen connectivity. Both feature curved AMOLED displays with 1.5K resolution, 144Hz refresh rate, and up to 4,500 nits peak brightness, delivering sharp, vibrant visuals for gaming, streaming, and outdoor use.

Smarter Interactions and AI Features

The phone introduces a Mood Light design with two circular “eyes” on the back that express emotions with light animations during calls, charging, or notifications. It also comes with TECNO AI features, including real-time translation, AI-powered writing tools, Circle-to-Search, and the Ella AI assistant. Additional features such as multifunctional NFC, HiOS based on Android 15, and FreeLink connectivity enhance everyday usability.

Pioneering a New Era for Ultra-Slim Phones

TECNO Slim is more than a smartphone; it is a redefinition of what slim technology can achieve. Within just half a year of development, TECNO has merged slim design, durability, and class-leading performance, creating a device tailored for both global and emerging markets. By delivering compromise-free design with powerful performance, TECNO Slim sets a new benchmark in the evolution of smartphones, proving that thinner can indeed be stronger.

TECNO used the stage of IFA ShowStoppers 2025 to present some of its most ambitious product launches yet. Under the theme “The Thinnest Power Duo,” the company revealed the global debut of its TECNO Slim smartphone and also highlighted its new MEGABOOK S14 laptop. The presentation marked not only a step forward in slim device innovation but also confirmed TECNO’s expansion of laptops into Spain and France, two of Europe’s fastest-growing tech markets.

Strong Laptop Push in Spain and France

Spain has become the first major European country where TECNO laptops are now widely available. The lineup includes the MEGABOOK K15S, K16S, and the compact MEGA MINI G1 gaming PC. Reviews from Spanish tech outlets such as Xataka, Topes de Gama and Computer Hoy praised the products for their balance of performance, portability and price. The MEGABOOK K16S AMD version has been highlighted as a strong budget-friendly choice, while the K15S stands out for its premium design and durability.

Partnerships have played a major role in this expansion. TECNO has teamed up with MCR, Spain’s largest technology distributor, as well as retail giants MediaMarkt and Carrefour. This allows the laptops to be sold both online and in stores. The company has also announced that the flagship MEGABOOK S14, the lightest 14-inch OLED laptop at only 899 grams, will reach select European markets in the final quarter of 2025.

TECNO Slim Smartphone Leads Innovation

The star of TECNO’s showcase is the new TECNO Slim, a smartphone that claims the title of the world’s slimmest 3D curved device. Measuring only 5.93mm (4G) and 5.95mm (5G), it manages to pack in a 5160mAh battery with 45W fast charging. It also comes with a 144Hz AMOLED display protected by Gorilla Glass Victus 3 and is built to military-grade durability standards. On the software side, the phone integrates AI features such as real-time translation, AI writing tools, and Circle to Search, offering users both style and advanced intelligence.

Tablets and AIoT Products Join the Lineup

TECNO also introduced the MEGAPAD Pro, a 12-inch AI-powered tablet designed for students and professionals. It has a 2K display, Dolby sound, 90Hz refresh rate and a large 10,000mAh battery. AI features like image-based Q&A, smart screen recognition and a shortcut key for the Ella Voice Assistant make it suitable for work and learning.

In addition, TECNO expanded its AIoT ecosystem with new wearables and accessories. These include the TRUE 2 AI TWS earbuds, the Watch GT AI Smart Watch and several smart home and lifestyle gadgets. All of these products aim to create a connected and seamless experience across devices.

Aiming for a Smarter Digital Lifestyle

According to Ye Yuan, Head of TECNO AIoT, the company’s focus in Europe is to deliver products that balance modern design, powerful performance and affordable value. TECNO follows a “Glocalization” strategy, meaning it combines global innovations with features tailored to local needs. 

With its new smartphone, laptops, tablets and AIoT products, TECNO has made it clear that it is ready to compete in Europe’s highly competitive tech market. The company’s entry into Spain and France is not just a regional expansion, but a signal that it is aiming to become a bigger name in global consumer technology.

Mobile World Congress (MWC) Barcelona features the best of consumer tech from all around the world. Interestingly, some of the coolest products that you see at the event are concepts, which showcase the possibilities and the direction that smartphone and consumer brands will move towards in the coming years.

Brands like Lenovo and even Tecno have showcased their concepts before, but we have a few more additions this year, and its not about foldable screens (its mainstream now after all) anymore. 

So here were the coolest products that I saw at MWC 2025. 

Lenovo Solar Charging Laptop

Every year Lenovo showcases something cool at MWC, and this year was no different, with the company featuring a rollable laptop, a foldable laptop, and a solar laptop at its booth.

To be honest, we have seen rollables, foldables before, even in the laptop category, and while they are cool, what really caught my attention was the solar charging laptop.

Lenovo’s solar-powered laptop features solar panels on the outside, which helps charge the device under sunlight. It works outdoors as well as indoors, given enough reflective sunlight. Lenovo claims you can get up to 1 hour of video in just 20 minutes of charging. 

The fact that this is possibly coming to stores next year makes it a really cool product that I’m looking forward to. 

Note that black is not the only color option that could be available, as Lenovo seems to be testing different colors too.

Xiaomi 15 custom edition with Modular Lens

The Xiaomi 15 Custom edition is a concept that envisions snap-on lenses on a regular smartphone using magnetic pins on the back.

This concept model features pins that lock and connect the add-on lens to the smartphone camera, treating the accessory as a part of its traditional camera setup. Imagine the possibilities such a design would bring to phones, enhancing the already versatile camera setup of new-age devices.

Unfortunately, we don’t know if this will ever make it to the market, but wouldn’t it be cool to change the lens on your smartphone depending upon your requirement?

Pet smartphone

While this device might seem extravagant to some, pet enthusiasts would disagree. For many pet owners, their furry companions are as cherished as children, making a collar phone that enables direct connection not just reasonable but essential for peace of mind.

The pet phone provides two-way interaction, much like any other smartphone, along with AI health monitoring and GPS positioning. What’s really cool is that pets can potentially initiate a call using predetermined gestures.

How well does it work in real life? I couldn’t test it, but the idea was definitely promising

LiFi getting closer to Commerical Launch

LiFi allows low latency, extremely high-speed transfer of data to devices in direct line of sight. This relatively new technology will soon be in commercial devices, including smartphones.

For those who don’t know, LiFi is like Wi-Fi but faster, more secure (due to its limitations), and provides better latency too.

LiFi is not going to replace your Wi-Fi setup, but it will complement it. Imagine LiFi as a solution that’s as good as wired solutions but without the clutter. So LiFi could power and connect your devices indoors, even ones requiring higher bandwidth and lower latency, in a true wireless manner. To give you some perspective, imagine an LED light bulb in your room, providing up to 224 Gbps of data speed. That’s way faster than traditional Wi-Fi.

At MWC 2025, I checked out LiFi and their prototype smartphone with the LiFi module and saw the technology in action.

The commercialization will take a few more years, but pureLiFi is already talking to carriers and consumer tech brands to integrate their receiver into smartphones.

Lenovo Magic Bay Accessories

The Lenovo Magic Bay is one of the most practical concepts that I saw at the event this year and would probably love to have on my Macbook too.

The idea is pretty simple. You have magnetic pogo pin connectors on the back of your laptop, which allows you to add a bunch of accessories like displays, AI assistant companion hardware, and so on.

Lenovo showcased two concept accessories that utilized this pogo connector, one small add-on display that pops up right on top of the existing screen, and another concept with two 13.3-inch dual displays, adding 3 screens in total to the Thinkbook model. 

Tecno Spark Slim

Are slim smartphones cool again?

10 years ago, there was a phase when slim smartphones became extremely popular. These phones flaunted their sleek looks at the cost of a small battery, but eventually brands realized that people prefer a phone that lasts a day than one that goes dead in a few hours.

This year, Tecno decided to spin off its own version of the slim phone concept at MWC 2025, bringing an impressive 5200mAh battery in a super slim 5.75mm design. The smartphone concept looked pretty chic and curvy, and I’m sure there will be a section of the population who would love to grab hold onto a device like this for their daily use.

Doogee V Max Play

Is it a smartphone or is it a projector? Or is it both?

Well, in the case of the Doogee V Max Play, its both!

The phone features a gigantic 22000mAh battery and is thick as a brick. But you get a projector on the go, ensuring your gaming or movie sessions are never limited by the small screen.

The quality isn’t the best, but if you project it over a small area, it’s definitely usable.

Meizu StarV Air 2

Meizu is back, now under the umbrella of DreamSmart. But this time around, I was more excited about their glasses than smartphones.

The glasses, which I could try out for some time at their booth, offered live translation, navigation, and even a teleprompter, which worked in real time.

The glasses look like any other regular specs, which means the person in front of you would be pretty amazed when you can understand different languages or even present a flawless presentation without missing a single word.
