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.
