Top ultra thin smartphones of 2025 you can buy or watch for

As 2025 unfolds, the competition to create the sleekest smartphones is intensifying. Manufacturers are merging elegant designs with robust technology, aiming for record-thin profiles. Here's a glimpse at some of the most remarkable ultra-thin smartphones expected this year. Leading the charge is Samsung with its newly launched S25 Edge, the thinnest smartphone of 2025, measuring just 5.8mm and weighing in at approximately 163 grams. Despite its slim frame, it retains top-tier features such as a 200 MP camera and a stunning 6.7-inch 120Hz Dynamic AMOLED 2X display. It is powered by the Snapdragon 8 Elite chipset, similar to that of Samsung's flagship S25 series. However, to achieve this slender design, the battery has been reduced to a 3900 mAh capacity with 25-watt wired charging. Priced at ₹1,09,999, it’s a premium offering for those seeking a stylish, ultra-thin device. Tecno is pushing the envelope with its Spark Slim concept phone, boasting an impressive thickness of 5.75mm and a lightweight of 146 grams. Remarkably, it houses a 5200 mAh battery, along with 45-watt charging capabilities, outpacing many current smartphones in battery performance. This innovative design cleverly arranges internal components to maintain essential functionalities without sacrificing its slim profile. Although its release date remains uncertain, there is significant anticipation for Tecno to introduce the Spark Slim in India, catering to the growing demand for stylish gadgets. Rumors are swirling about Apple’s upcoming iPhone 17 Air, which is expected to redefine the standards of slimness with a body thickness of merely 5.4mm. Set to launch alongside the iPhone 17 series, the iPhone Air is likely to incorporate the next-generation A-series chip and advanced OLED display technology, focusing on a lightweight and minimalist aesthetic. Apple aims to strike a balance between high performance and battery efficiency in this compact design, targeting users who appreciate both cutting-edge innovation and portability. Meanwhile, Oppo’s Find N5 foldable smartphone makes a bold statement, achieving a remarkable 4.21mm thickness when unfolded. It features a vibrant, crease-reduced display and a durable hinge, ensuring a seamless transition between folded and unfolded states. Perfect for those who desire a large screen without the bulk, this device is expected to make waves in the Indian market, thanks to Oppo's history of delivering innovative solutions. Lastly, the Honor Magic V3 stands as one of the slimmest foldable smartphones globally, measuring just 4.4mm when opened. It offers an expansive, immersive display while remaining lightweight and pocket-friendly. With its advanced hinge design and robust materials, the Magic V3 promises to combine flexibility with durability, appealing to users who seek performance without added bulk. The future of ultra-thin smartphones looks bright, with these models leading the charge in innovation and design.
