The Mobile World Congress (MWC) 2025 event showcased a diverse array of groundbreaking technologies, with leading tech giants such as Google, Samsung, Lenovo, Infinix, and Tecno unveiling their latest innovations. From concept devices that push the boundaries of design to real-world advancements that will soon hit the market, MWC 2025 set the stage for the next wave of mobile evolution. Among the numerous announcements, a few smartphones stood out due to their unique designs, cutting-edge specifications, and potential to redefine industry standards. Notable mentions include the Samsung Galaxy S25 Edge, Infinix's revolutionary tri-folding phone, and Tecno's record-breaking ultra-thin smartphone.
Samsung’s Galaxy S25 Edge was one of the most anticipated reveals, following its initial teaser in January alongside the launch of the standard Galaxy S25 series. At MWC 2025, Samsung officially showcased the device, drawing significant attention due to its ultra-slim profile and premium aesthetics. Reports suggest that the Galaxy S25 Edge will be released in April and will stand out as one of the thinnest flagship smartphones ever created. Samsung has reportedly achieved this design feat by re-engineering core components, allowing for an impressive reduction in thickness. The front of the device is expected to be similar to the Galaxy S25+, featuring a large, immersive display. However, one key difference lies in the rear camera setup—while the S25+ sports a triple-camera system, the Galaxy S25 Edge will come equipped with just two sensors.
Performance-wise, the Galaxy S25 Edge is said to be powered by Qualcomm’s latest Snapdragon 8 Elite chipset, as confirmed by a recent Geekbench listing. However, despite its powerful internals, the device’s relatively small 3,900mAh battery has raised some concerns, as it may struggle to provide extended battery life, especially given the demands of a high-performance chipset and a sleek, lightweight design.
Another showstopper at MWC 2025 was the Infinix Zero Series Mini, a revolutionary tri-fold smartphone that pushes the limits of foldable technology. Designed to function as a smartphone, tablet, and compact laptop all in one, the Zero Series Mini features dual hinges that enable its triple-folding mechanism. This allows users to adjust the device to different form factors depending on their needs, whether for multitasking, media consumption, or productivity. This innovation could redefine smartphone versatility, consolidating multiple gadgets into a single device.
Adding to the excitement, Infinix also introduced a new color-shifting technology that enables users to change the color of their smartphone’s rear panel at the press of a button. Initially teased last year by India CEO Anish Kapoor, this technology has now been officially announced on a global scale. Infinix’s E-Color Shift 2.0 technology supports up to 30 distinct color variations, allowing for a customizable aesthetic that adapts to user preferences.
Meanwhile, Tecno made waves with its SPARK Slim smartphone, which is poised to be the world's thinnest handset. Competing directly with Samsung’s Galaxy S25 Edge, the SPARK Slim aims to set new records in smartphone design. Tecno revealed at MWC 2025 that the device will house an impressive 5,200mAh battery, despite its remarkably thin body. It is confirmed to feature a 6.78-inch 3D Curved AMOLED display, a 50-megapixel dual-camera system on the back, and a 13-megapixel front camera. Measuring just 5.75mm in thickness, it could dethrone the Galaxy S25 Edge as the slimmest smartphone on the market. While the SPARK Slim’s chipset remains undisclosed, it has been confirmed to be powered by an octa-core processor, with more details expected at its official launch.
MWC 2025 has proven once again to be the ultimate platform for mobile technology innovation. With Samsung refining ultra-slim flagship designs, Infinix redefining foldable with tri-fold technology and dynamic color-shifting panels, and Tecno pushing the limits of thinness while maintaining a large battery, this year’s event has set the stage for an exciting wave of smartphone launches in the coming months.
