Why Choosing a Lightweight Phone Matters in 2025
There’s more to a smartphone than specs and screen size—weight plays a huge role in day-to-day comfort. Whether you’re scrolling through social media, messaging, commuting, or taking calls, a lighter, slimmer phone reduces hand fatigue and pocket bulk. And after 2025’s trend toward ultra-thin flagships, being featherweight no longer means sacrificing performance. Let’s dive into the lightest contenders.
🥇 1. Samsung Galaxy S25 Edge—163 g, 5.8 mm
The Galaxy S25 Edge tops our list as Samsung’s thinnest and lightest flagship—a mere 5.8 mm thick and 163 g in weight. It’s packed with a large 6.7-inch QHD+ AMOLED display, Snapdragon 8 Elite, 12 GB RAM, and a 200 MP main camera. Despite the slim build, it still manages Qi2 wireless and wired charging—though power users may find the 3,900 mAh battery modest.
🥈 2. iPhone 17 Air (Rumored) – ~145 g, ~5.5 mm
Apple’s rumored “Air” variant is expected to be the lightest iPhone yet—about 145 g and ultra-thin at 5.5 mm. Leaks point to a 6.6‑inch OLED screen, A19 Bionic chip, and 48 MP camera, but the trade‑off appears to be a compact 2,800 mAh battery—meaning potential for external battery assistance.
🥉 3. OnePlus 13 – 210–213 g, ~8.5–8.9 mm
OnePlus returned to compact-ish dimensions with the OnePlus 13, released internationally in early 2025. Featuring a Snapdragon 8 Elite chip, 6000 mAh silicon-carbon battery, and blazing-fast 100 W charging, it balances high performance with relatively moderate weight and thickness (~8.5 mm, 210–213 g).
4. Motorola ThinkPhone 25 – 171 g
Motorola’s collaboration with Lenovo’s ThinkPad division brought us the ThinkPhone 25 in November 2024, a solid all-rounder: 6.36-inch P-OLED screen, reliable 50 MP camera with OIS, and a 4,310 mAh battery—all in a compact 171 g package.
5. Motorola Moto S50 – 171 g
Also in the same weight class, the Moto S50 (launched September 2024) mirrors the ThinkPhone 25 in weight and display specs, with a similar 4,310 mAh battery and triple-camera setup.
6. Asus Zenfone 10/9—169–172 g, ~9 mm
Not in the headlines often, but within enthusiast circles, the Asus Zenfone 10 (and its predecessor, the Zenfone 9) merit a shout-out. Both maintain a compact 5.9–6.1 inch screen and stay around 169–172 g, offering flagship performance in a pocket-friendly shell.
7. Xiaomi 15 – 181 g, 8.08 mm
Xiaomi’s flagship 15 series (Mar 2025) packs a 6.36‑inch OLED, 120 Hz refresh, and Snapdragon 8 Elite, all while weighing a smooth 181 g. A balanced choice for those seeking flagship specs in a lightweight body.
8. Vivo V27 Pro – 182 g, 7.4 mm
From mid-2023 but still relevant in weight rankings, the Vivo V27 Pro offers a flashy color-changing back, Dimensity 8200 chip, and P-OLED screen, all for 182 g. A favorite among style-conscious users.
9. Xiaomi Poco X7 – ~185.5 g
Announced in January 2025, the Poco X7 brings a 6.67-inch AMOLED, a 50 MP OIS camera, and solid battery life, yet weighs in at a relatively light 185.5 g. A value-packed option for fans of mid-range performance.
10. Samsung Galaxy S25 – 162 g (Body)
Though the Edge version is the headline light-and-thin variant, the regular Galaxy S25 (standard model) is also among the lightest flagships at 162 g with a 6.2‑inch display—great for those preferring a smaller body.

📝 Observations & Buyer Tips
1. 📱 Flagship vs Value
Ultra-light flagships (S25 Edge, iPhone 17 Air) prioritize portability but may compromise on battery size and telephoto cameras. Mid-range options like the Poco X7 and Motorola devices may not be ultra-thin but strike a better specs-to-weight balance.
2. 🔋 Battery vs Body
Slim designs mean smaller batteries. The S25 Edge’s 3,900 mAh may last a day with lighter use (theguardian.com, wired.com, 91mobiles.com, askvg.com, en.wikipedia.org, indianexpress.com, gsm.cool, en.wikipedia.org, th.gsm.cool), and the rumored iPhone 17 Air’s 2,800 mAh will likely require smart power management or extras.
3. 🌍 India-Specific Picks
Our Indian market options favor the S25 Edge/S25 and mid-range Xiaomi/Poco/Xiaomi 15, Vivo V27 Pro, and Motorola G/Think phone.
4. 🧭 Look Beyond Weight
Even at similar weights, thickness, ergonomics, build materials (e.g., titanium for S25 Edge), and display size impact comfort. Try handling key models before deciding.

❓ FAQs on Lightweight Smartphones
Q: Are ultralight phones fragile?
Not necessarily. The S25 Edge, for instance, uses a titanium frame and Gorilla Glass Ceramic 2 to retain strength despite its thinness.
Q: Do lighter phones have worse battery life?
Quite often, yes—smaller size limits battery capacity. It’s vital to check real-use battery reviews (like 24-hour video playback tests for the S25 Edge).
Q: Is a 163 g phone really noticeable?
Yes. Many flagships weigh 200 g+. Even 10–20 g can make a phone feel significantly lighter during extended daily use or holding it one-handed.
📌 Final Take
The Samsung Galaxy S25 Edge currently leads as the lightest feature-rich flagship. But for users prioritizing battery life, the OnePlus 13 or Xiaomi 15 deliver more longevity without much added weight. Mid-range alternatives like the Vivo V27 Pro, Poco X7, and Motorola ThinkPhone 25 offer compelling options for those who want to stay light without stretching the budget.
In India, availability and pricing (e.g., ₹65 k for Galaxy S25, ~₹35 k for Poco X7/Vivo V27 Pro) will guide final decisions. Weigh your priorities—pun intended—and your next phone could feel like a feather in your pocket, not a burden.
