5 slim, smart, and surprisingly lightweight phones of 2025

Smartphones in 2025 aren’t just about raw power or megapixels; they’re about feel. And in this post-pandemic era of hybrid living and relentless doomscrolling, weight is quietly becoming a spec that matters again.

With phone screens stretching past 6.7 inches and batteries pushing way past the 5,000mAh ceiling thanks to silicon carbon tech, manufacturers are rethinking design language to deliver devices that don’t weigh your pocket down like a brick.

The result? A wave of 2025 smartphones that pack flagship power and slick aesthetics into bodies lighter than ever. Even Apple is expected to soon unveil its first slim device, while Samsung has already debuted its slim champion, the S25 Edge.

Top 5 slim smartphones of 2025

Here are five standout slim phones, across budgets, that prove you don’t need heft for high-end function:

– Samsung Galaxy S25
– Samsung Galaxy S25 Edge
– Xiaomi 15
– Google Pixel 9a
– Vivo V50

1. Samsung Galaxy S25 (162g)

Samsung kicked off 2025 by proving that premium doesn’t have to be heavy. At just 162 grams, the Galaxy S25 is the lightest flagship in recent memory, running on the custom 3nm Snapdragon 8 Elite co-engineered with Qualcomm.

The design trims the fat from its predecessor, the S24, with a tighter internal layout and lighter materials, all without sacrificing a 4,000mAh battery or triple-camera system (including a 50MP main sensor). The 6.2-inch AMOLED display and IP68 rating wrap it up into a sleek, comfortable, high-end package.

2. Samsung Galaxy S25 Edge (163g)

Samsung’ futuristic S25 Edge dials the thinness up to 11. At just 5.8mm thick and 163 grams, it’s Samsung’s lightest “phablet-class” flagship, boasting a massive 6.7-inch display, 12GB RAM, and the same Snapdragon 8 Elite power.

It ditches the telephoto lens and trims the battery to 3,900mAh to achieve this featherweight feel. The result? A device that looks and feels impossibly light for its screen size.

3. Xiaomi 15 (189g)

At a glance, the Xiaomi 15 might seem like any premium slab, but at 189 grams, with a 5,240mAh battery, it’s a feat of clever engineering.

Xiaomi combines a slim 8.1mm profile, a Leica-tuned 50MP triple-camera system, and 90W fast charging into a device that’s lighter than most flagships with comparable batteries. It’s a reminder that longevity and lightness can coexist in a flagship design.

4. Google Pixel 9a (186g)

Google’s Pixel 9a hits the sweet spot of size, weight, and stamina. At 186 grams, it’s lighter than the flagship Pixel 9 but still packs a 5,100mAh battery, a 6.3-inch OLED screen, and the latest Tensor G4 chip.

The plastic-aluminium build keeps it light without feeling cheap, while the IP67 rating and dual-camera setup (48MP + 13MP) bring durability and versatility. It’s a midrange phone that feels refreshingly light in the hand and heavy on value.

5. Vivo V50 (189g)

Vivo has quietly built a reputation for well-balanced midrange phones, and the V50 continues that streak. With a 6.7-inch AMOLED screen and a 5,000mAh battery, it should feel hefty, but it doesn’t.

At 189 grams, it feels unexpectedly light, especially compared to rivals in the same segment. The Snapdragon 7 Gen 3 chip, 90W fast charging, and dual 50MP cameras complete the package. Vivo didn’t compromise on screen size or endurance; it just engineered smarter.

Slim phones in 2025

These phones prove that power and portability can coexist. As the industry shifts away from the obsession with bigger batteries and bulkier builds, these devices stand as a testament to what’s possible with smarter engineering and design.

Whether you’re a flagship enthusiast, a midrange loyalist, or just someone tired of feeling weighed down by your phone, these models remind us that lighter doesn’t always mean less. It often means more freedom, more comfort, and more possibilities in hand.
