In 2025, smartphones have moved beyond focusing solely on speed, battery capacity, or photographic capabilities; instead, their emphasis is now on how they feel when held. Weight has once again become an important specification. With phone displays expanding and batteries exceeding the 5000mAh threshold, certain manufacturers are countering this trend towards heavier devices through innovative designs, lighter components, and more efficient construction techniques. This shift leads to a fresh generation of gadgets that offer top-tier performance along with substantial functionality but do so within sleeker frames that tip the scales at unprecedentedly low weights.
Below are seven of the lightest smartphones unveiled in 2025, spanning flagship, mid-range, folding, and budget categories, demonstrating that premium performance doesn’t have to come with extra weight.
1. The Samsung Galaxy S25 weighs 162 grams.
Samsung started the year off strongly with the Galaxy S25 , a phone that goes back to fundamentals in the most effective manner. Weighing only 162 grams, it stands out as one of the lighter high-end smartphones we've seen recently, maintaining robust performance despite its slim profile. The device operates using the 3nm Snapdragon 8 Elite chip, which was developed jointly with Qualcomm , accompanied by a 4000mAh battery and a triple-lens camera setup featuring a 50MP primary sensor.
It's uncommon for a high-end phone featuring a glass-and-metal design to weigh less than 170 grams, but Samsung succeeded in reducing the weight of last year’s model, the S24 (which was around 167 grams), through material improvements and optimized internal structures. With its 6.2-inch AMOLED display, an IP68 water-resistance rating, and Gorilla Glass Victus 2 coating, this device feels far from basic. The Galaxy S25 serves as proof that luxury can come without added bulk.
2. Samsung Galaxy S25 Edge (Weight: 163g)
If the S25 embodies compact elegance, then S25 Edge is its futuristic twin, sleek, long, and impressively thin. At just 5.8mm thick and 163 grams, this 6.7-inch phone is lighter than many smaller devices. Samsung gave it the same Snapdragon 8 Elite processor and 12GB of RAM, but it sacrifices the telephoto lens and drops the battery slightly to 3900mAh to maintain that razor-thin profile.
It's not so much about having the strongest specs on paper but rather demonstrating what can be achieved when design takes precedence. Samsung refers to this as the lightest "phablet-class" flagship from 2025, and it truly feels that way in your hands—lightweight, robust, and unexpectedly comfortable considering its dimensions.
3. Xiaomi 15 (189–191g)
At first glance, Xiaomi ’ newest top-of-the-line model may appear as just another high-end device. However, weighing less than 191 grams and equipped with a 5240mAh battery, the Xiaomi 15 It stands out from the ordinary by merging durability with sleekness within a small frame. This device features a 6.36-inch AMOLED screen, a high 120Hz refresh rate, powered by a Snapdragon 8 Elite processor, complemented by a Leica-calibrated triple 50MP camera setup.
Featuring 90W wired charging and a sleek 8.1mm thickness, Xiaomi demonstrates how to optimize without overcrowding. In a marketplace where many high-end phones with batteries above 5000mAh tip the scales at more than 210 grams, the Xiaomi 15 distinguishes itself as an astute effort in harmonizing design and performance.
4. Google Pixel 9a (Weight: 186g)
Google’s Pixel 9a It strikes an ideal balance in terms of size, weight, and simplicity. Weighing just 185.9 grams, this device is the lightest model within Google's offerings for 2025, surpassing even their top-tier Pixel 9. Despite being so lightweight, you'll find features like a 6.3-inch OLED display, the newest Tensor G4 processor, along with a substantial 5100mAh battery.
The design is sleek and functional, featuring a plastic-aluminum frame that minimizes weight without sacrificing quality. It comes equipped with wireless charging, IP67 waterproofing, and a dual-lens camera system (48MP primary sensor plus a 13MP ultra-wide lens). Although it may not be the lightest device around, as a mid-range 5G smartphone offering substantial battery life, the Pixel 9a has a pleasantly lightweight feel when held.
5. Vivo V50 (189g)
Vivo has discreetly earned a reputation for producing well-rounded mid-range smartphones, and the V50 maintains this trend. Featuring a 6.7-inch AMOLED display and a 5000mAh battery, one might expect it to be cumbersome, yet it isn’t. Weighing just 189 grams, the Satin Black version of the V50 seems surprisingly lightweight when stacked against comparable models that often exceed 200 grams.
This device is equipped with a Snapdragon 7 Gen 3 processor paired with up to 12GB of RAM, offers support for 90W rapid charging, and features twin 50MP cameras. The phone boasts a sleek profile at just 7.4mm thick, making it comfortable to hold and easy to slip into your pocket. Despite its slim build, Vivo maintained generous dimensions both in terms of display size and battery life by focusing on innovative engineering solutions rather than cutting corners.
6. Motorola Razr Ultra 2025 (199 grams)
Foldable devices are known for their thickness, but Motorola ’s 2025 Razr Ultra shows that they don't have to be heavy. Even with a 7-inch internal screen, a 4-inch external display, and a massive 4700mAh battery, the Razr Ultra tips the scales at only 199 grams. This is quite rare in the world of foldable devices.
The combination of the Snapdragon 8 Elite processor and 16GB of RAM makes this device highly powerful, but the real standout features are the titanium hinge and well-thought-out internal design. In contrast, Samsung’s Z Flip 6 (2024) weighs approximately 188g and has a much smaller battery. Motorola opted for additional weight to ensure all-day battery performance, which seems like a reasonable trade-off.
7. Tecno Spark Slim (166 grams)
At MWC 2025, Tecno stunned the technology community with the unveiling of the Spark Slim, a concept phone that seems plucked directly from a science-fiction movie. Weighing in at 166 grams and boasting a thickness of merely 5.75mm, this device has set new standards for sleek design. It's the slimmest smartphone unveiled so far. , despite this, it comes with a 5200mAh battery. Indeed, it’s true.
This phone serves more as a concept demonstration rather than an everyday use device, featuring average specifications and restricted accessibility. However, it underscores that slimness and lightweight design can be achieved even within affordable price ranges. Regardless of whether the Spark Slim reaches widespread markets, it establishes a fresh standard.
