The Mobile World Congress (MWC) 2025 in Barcelona once again served as a global stage for tech companies to showcase their latest innovations.
While flagship smartphone announcements have become less frequent at the event, this year still brought a variety of exciting new gadgets, AI advancements, and futuristic concepts. From an ultra-slim smartphone to a solar-powered laptop and AI-driven assistants, here’s a look at the most notable tech revealed at MWC 2025.
Xiaomi’s new 15 and 15 Ultra smartphones have generated considerable buzz. With high-quality displays, strong battery performance, and fast charging, these Android devices stand out in the premium segment. Xiaomi’s HyperOS 2 introduces more AI-driven features, and the Ultra model even comes with an optional photography kit, offering dedicated camera controls and an extra battery. Unfortunately for US consumers, these devices are only launching in the UK and Europe.
Nothing introduced two new mid-range smartphones—the Phone (3a) and Phone (3a) Pro—which share similar specifications apart from their cameras. The 3a Pro features a 50-megapixel main camera with a 3X optical zoom lens, while the standard 3a has a 2X optical zoom camera. With pricing set at $379 and $459, respectively, these models bring premium camera features to an affordable price range.
Honor unveiled a screen-reading AI agent that can perform tasks based on what’s displayed on a phone screen. Although still in development, this technology could significantly improve smartphone automation. Honor also launched the Watch 5 Ultra, a lightweight smartwatch with a sapphire crystal face and up to 15 days of battery life, along with the Honor Earbuds Open, which feature active noise cancellation and real-time AI translation.
In response to growing concerns about online safety for young users, HMD introduced the Fusion X1, a phone designed specifically for teenagers. It includes features such as location tracking, content filters, emergency SOS calling, and a School Mode to limit distractions during class hours. Parents can access these tools for a €5 monthly subscription.
Tecno showcased the Spark Slim, a concept phone that measures just 5.75 mm thick, making it one of the slimmest non-foldable smartphones available. Despite its thin design, it boasts an impressive 5,200-mAh battery. While still a prototype, it highlights the industry’s shift toward ultra-slim devices.
Google announced that its Gemini Live AI assistant will soon support real-time video analysis. Users will be able to open their phone’s camera and ask Gemini questions about objects in their environment, an upgrade powered by Google’s Astra AI technology. This enhanced version of Gemini will be available exclusively for Gemini Advanced subscribers later this month.
Lenovo introduced the Yoga Solar PC, a concept laptop equipped with built-in solar panels, allowing it to charge using sunlight. While not the first solar-powered laptop, Lenovo claims it is the world’s first ultra-slim solar-powered model. The company also showcased the ThinkBook Flip, a laptop with a second screen that folds over the lid for increased display real estate.
Realme launched the 14 Pro+, a midrange smartphone featuring a 6.83-inch curved display, a 50-megapixel periscope telephoto lens, and a 6,000-mAh battery with 80W fast charging. Priced at €530 (€430 for early buyers), it offers high-end features at a competitive price.
Motorola announced updates to Smart Connect, its software that links Motorola smartphones to Lenovo laptops and tablets. The latest version introduces AI-powered search and voice commands, allowing users to locate files across multiple devices or open phone apps on a connected laptop with voice commands.
