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.

The Mobile World Congress has returned to its full glory in 2023, with thousands of attendees and brands participating in one of the largest tech fairs in the world. The event officially commenced today, February 27, and will continue until March 2. The first day of the event is typically the busiest, as brands compete to unveil their most significant products and technological advancements on the opening day.

As expected, the first day of MWC 2023 was packed with activity, with numerous announcements from high-profile brands such as Huawei, Honor, Oppo, OnePlus, Lenovo, and others. Given the vast number of products showcased at the event, let’s quickly review the standout product announcements made on the first day of the event.

Here are the Best Products & Announcements of MWC 2023

Lenovo’s Rollable Concept Smartphone & Laptop

MWC 2023’s first day kicked off with two interesting products on display – the Rollable Concept laptop and the Moto Rizr rollable smartphone.

As foldable smartphones and even laptops are gaining popularity, Lenovo’s take on a rollable form factor looks a lot more promising. Both the smartphone and the laptop can extend their screen size to suit your requirement, with a single push of a button. While the Rizr looks very interesting and some might even prefer it over a traditional foldable, the rollable laptop concept looks a lot more viable.

The rollable laptop comes with a standard 12.7-inch display with a 4:3 aspect ratio in its default mode. However, with the push of a button, a pair of internal motors smoothly extend the screen from beneath the laptop’s keyboard to an almost square 15.3-inch display with an 8:9 aspect ratio, providing a significantly larger viewing area.

Here are more details on the Rollable Rizr Smartphone and Lenovo’s Concept Laptop.

LiFi – The next evolution in Wireless Connectivity?

Li-Fi or Light Fidelity is a wireless technology that utilizes light to transmit data between two devices. The technology employs light-emitting diodes (LEDs) to send data at high speeds over the visible light spectrum. It comes with several advantages over Wi-Fi, such as faster speeds and even better security. However, it requires a direct line of sight between the transmitter and receiver, limiting its implementation.

That said, Li-Fi may go mainstream as smartphones could soon add Li-Fi as another wireless communication technology. This is made possible by pureLiFi’s Light Antenna One, a first-of-its-kind wireless communications antenna, that implements this technology on smartphones and other connected devices at a large scale. The device is compliant with the forthcoming IEEE 802.11bb standard, so manufacturers can seamlessly integrate LiFi with existing 802.11 Wi-Fi networking equipment and the billions of devices that currently use 802.11 Wi-Fi chipsets annually.

Satellite Comms Go Mainstream on Phones, Thanks to Qualcomm

Satellite communication is the new buzz in the smartphone industry with major players like Apple, Samsung, and even Huawei (rumored) integrating this technology into their smartphones and devices. However, Qualcomm is making satellite communications more accessible to smartphone manufacturers by integrating this feature into multiple RF modems and its 8 and 4 series of processors for smartphones. The company has partnered with the satellite service provider Iridium to bring two-way texting and more emergency satellite communication options to smartphones.

So if you were feeling left out by the announcements from Apple and Samsung, fret not as Qualcomm confirms most major manufacturers like Xiaomi, Vivo, Motorola, Oppo, Honor, and Nothing are going to bring satellite communication to their smartphones in the near future. Unfortunately, we don’t have a timeline yet on when it will be available on these manufacturer devices.

It is worth noting that MediaTek is also bringing a similar feature (in partnership with Bullitt).

OnePlus 11 Concept Gets Glowing Liquid Cooling

OnePlus’ awaited OnePlus 11 Concept smartphone was officially unveiled today and the wait was fairly justified because it brings a glowing liquid active cooling technology called Active CryoFlux. The OnePlus 11 concept can bring the thermals down during gameplay by up to 2.1℃ and during charging by around 1.6℃. OnePlus claims this technology can increase the frame rate by up to 3 to 4 fps and reduces the charging time by around 30 to 45 seconds.

Along with the smartphone, OnePlus showcased an even more interesting gadget – a 45W Liquid Cooling Accessory that can reduce phone temperature by up to an impressive 20℃.

Tecno Has A Color Changing Chameleon Smartphone

Tecno’s love for color-changing smartphones isn’t new. Last year we saw the Tecno Mondrian edition with unique color-changing technology. At MWC 2023, it takes things to another level with its Chameleon Color Changing Smartphone concept.

The smartphone allows you to manually select from a total of 1600 different colors using the device software, or it can be set to vary automatically based on the battery level, music, or notifications. The material can change its color in just 0.03 seconds and also utilizes very little energy; around 100 changes throughout the day will use energy equivalent to watching a 5-minute video.

You can read more about Tecno’s color-changing technology from our story here.

Two New Foldables – Honor Magic Vs & Tecno Phantom V Fold

MWC 2023 saw two new foldable launches.

Honor announced the Snapdragon 8 Gen1 powered Honor Magic Vs Fold, featuring a 6.45-inch external OLED 120Hz display and a 7.9-inch large 90Hz unfolded OLED screen. The Magic Vs will start at EUR 1599.

On the other hand, the Tecno Phantom V Fold is powered by MediaTek’s Dimensity 9000+ processor and has an ultra-clear 5-lens photography system featuring a 50-megapixel main camera and a super light-sensitive custom sensor. However, no more details are available about the device.

While Tecno has not shared any details about a potential launch of its foldable, it’s good to see more brands enter this market.

This is not only a feat of engineering but a leap in commercial maturity. LiFi connectivity can now be made available at scale to device manufacturers that want to differentiate, develop new products and foster new markets with leading-edge connectivity”. Says pureLiFi CEO, Alistair Banham

LiFi is a wireless technology that uses light rather than radio frequencies to transmit data. A light antenna is the optoelectrical antenna that is designed to integrate just like a traditional RF antenna and enables LiFi in connected devices. By harnessing the light spectrum, LiFi can unleash faster, more reliable wireless communications with unparalleled security, compared to conventional technologies such as WiFi and 5G.

Light Antenna ONE is optimised for performance, size, cost, and production requirements of the market which will allow smartphone and connected device manufacturers to integrate LiFi at scale. Compliance with the upcoming IEEE 802.11bb standard means that LiFi will easily integrate with existing 802.11 WiFi networking equipment and also with 802.11 WiFi chipsets shipping in billions of devices each year.

pureLiFi also revealed a series of concepts demonstrating how LiFi makes connectivity better at home and at work. This includes the LiFi Cube, a plug-and-play, LiFi gateway that enables fast, reliable and secure LiFi in the home, at work, and on the move. The HALO an accessory that offers high speed, low latency LiFi connections to AR/VR headsets. The team also exhibited LINXC 5G LiFi Bridge which shows how light can extend 5G, in particular mmWave, through windows when there are challenges extending 5G into buildings. For this application pureLiFi teamed up with Solace Power, wireless power experts from Canada, to demonstrate a solution that reduces cost and complexity of 5G fixed wireless access deployment to the home and office..

McKinsey Global Institute estimates that only about 70% of the global demand for digital connections leading up to 2030 will be satisfied by existing radio frequency (RF) and related technologies, even with advancements such as 5G and WiFi 6.

“LiFi is ready to pick up the connectivity shortfall and extend, enhance and secure wireless networks. Whether that is to enable secure home working, give gamers an edge, or help service providers extend 5G to new customers. We’ve demonstrated here that the applications of LiFi are broad, our technology is versatile and pureLiFi is ready to make connectivity better”. Alistair Banham explains.

Traditional wireless technologies such as 5G and WiFi suffer from growing congestion and interference that erode customer experience over time. They are also vulnerable to a range of security threats. LiFi not only offers inherent military grade security, it also enables fast, reliable and congestion free communications that will free up WiFi and 5G to perform better.

This latest advancement comes after multiple deployments with defence and government organisations to provide a range of solutions for reliable and secure mission critical communications. LiFi continues the classic journey of taking proven technology from the defence sector into hands of everyone. pureLiFi will be demonstrating the latest LiFi technology through the week at MWC in Barcelona and sharing their vision to connect everything and everyone with LiFi.
