OnePlus 13s

“Is it even possible to pack elite performance, a massive battery, and flagship design into a compact phone?” OnePlus just answered that with a resounding yes.

Introducing the OnePlus 13s, a device that doesn’t just check all the boxes—it smashes them. From the Snapdragon® 8 Elite chipset to the 5850mAh battery, the lifetime display warranty, and a classy Green Silk finish, this is a phone designed for those who want power, elegance, and reliability in their pocket without breaking the bank.

Let’s dive deep into what makes the OnePlus 13s the best value flagship killer of 2025—and how it stacks up against rivals in its price range.

Design: Compact Never Looked So Premium

The OnePlus 13s Green Silk variant is a visual delight. Inspired by luxurious Indian silk, the back panel feels smooth, matte, and smudge-resistant—meaning no more fingerprints turning your phone into a crime scene.

Despite its massive 5850mAh battery, the phone remains surprisingly light and compact—a rare combo these days. Think sleek, ergonomic, and pocket-friendly, yet durable and modern.

Bonus: It’s IP68 water- and dust-resistant. Spills and splashes? No worries.

Snapdragon® 8 Elite: Unleashing Raw AI Power

At the heart of the OnePlus 13s lies the Snapdragon® 8 Elite, Qualcomm’s fastest mobile chip yet. Paired with 12GB RAM and 256GB UFS 4.0 storage, this phone is a multitasking beast.

Whether you’re gaming with console-level graphics, editing 4K videos, or running AI-based productivity tools, the 13s handles it without breaking a sweat.

Real-World Test: Played Genshin Impact on max settings for an hour—zero lag, smooth frames, and thanks to the Cryo-Velocity cooling system, it stayed cool to the touch.

5850mAh Battery: Two-Day Battery Life? Yes, Please.

This might be the most impressive battery ever on a compact phone. With 5850mAh under the hood and ultra-optimized OxygenOS 15, I easily got 2 full days with heavy usage—YouTube, camera, social media, and some gaming.

Charging? Just 30 minutes to 100% with OnePlus’s crazy-fast 80W SUPERVOOC charging.

Standby drain? Barely noticeable. Leave it overnight, and it drops maybe 2–3%.

Camera: Flagship Performance for Everyday Creators

The OnePlus 13s might not have a Hasselblad label like its Pro siblings, but it still delivers stunning results.

  • 50MP Sony primary sensor with OIS: Sharp, detailed, and great dynamic range.
  • Ultra-wide: Crisp colors and minimal distortion.
  • AI enhancements: Portraits pop, low-light scenes shine.

Fun fact: The built-in AI detects pets and automatically optimizes the frame. My dog never looked this Instagram-worthy!

Lifetime Display Warranty: No More Broken-Hearted Screens

Yes, you read that right.

OnePlus 13s comes with a lifetime display warranty. Drop your phone and crack the screen? You’re covered. That’s unheard of in this segment.3

And this isn’t a basic panel either:

  • 6.55” AMOLED
  • 1.5K resolution
  • 120Hz refresh rate
  • HDR10+ certified

Vibrant, fluid, and bright even under harsh sunlight. Binge-watching, gaming, or just scrolling through Reels—it’s a delight.

OxygenOS 15: Smarter, Faster, Smoother

Running OxygenOS 15, the OnePlus 13s introduces a new level of AI integration. From smart app launch predictions to auto-organizing your day and summarizing documents, OnePlus AI learns how you use your phone.

It’s bloat-free, clean, and fast. And yes, still buttery smooth even after weeks of use.

Connectivity & Audio: Flagship-Grade Perks

  • Wi-Fi 7 & 5G Dual SIM support
  • Dual stereo speakers with Dolby Atmos
  • In-display fingerprint scanner
  • IR blaster to control TVs and ACs
  • Alert slider (still here, thankfully)
