Review

In the world of smartphones, the term “flagship” often evokes images of massive screens, hefty weights, and sky-high prices. But OnePlus seems to have broken the mold with its latest release  the OnePlus 13S. This compact powerhouse proves that good things can indeed come in small packages. With a sharp design, top-tier performance, and a surprisingly approachable price tag, the OnePlus 13S is already turning heads. Let’s dive into the OnePlus 13S specifications and see what makes this phone a standout in 2025.

Design

One of the first things you’ll notice about the OnePlus 13S is its size. Measuring 150.8 x 71.7 x 8.2 mm and weighing just 185g, it’s a breath of fresh air in a market dominated by oversized phones. Its flat AMOLED display, matte finish back, and aluminum alloy frame make it feel both premium and comfortable to use, especially with one hand. Available in Green Silk, Black Velvet, and Pink Satin, the phone also resists fingerprints thanks to its unique back texture.

Display

The display is a major talking point. It sports a 6.32-inch LTPO AMOLED panel with 1B colors, a 120Hz refresh rate, and support for Dolby Vision, HDR10+, and HDR Vivid. The resolution sits at 1216 x 2640 pixels (~460 ppi), offering stunning clarity. With 1600 nits brightness (HBM), outdoor visibility is top-tier. Protected by Crystal Shield Glass, the screen delivers both durability and beauty.

Peak Performance with Snapdragon 8 Elite

Under the hood, the OnePlus 13S is powered by the Snapdragon 8 Elite chipset built on a 3nm process. The octa-core CPU includes two high-performance cores at 4.32GHz and six additional cores clocked at 3.53GHz. Paired with the Adreno 830 GPU, performance is nothing short of stellar. Whether you’re multitasking, gaming, or streaming in HDR, the OnePlus 13S handles it effortlessly.

The device is available in two configurations: 256GB with 12GB RAM and 512GB with 12GB RAM. It uses UFS 4.0 storage, ensuring ultra-fast read/write speeds.

Battery Life That Surprises

Despite its compact size, the phone houses a massive 5850mAh battery, something rare in small flagships. With moderate use, it can easily last up to two days. And when you need to recharge, 80W wired charging, 33W PPS, 18W QC, and 5W reverse wired charging have you covered. A full charge takes less than an hour.

Clean and Fluid Software Experience

Running on OxygenOS 15 based on Android 15, the OnePlus 13S offers an incredibly smooth and fluid user experience. From intuitive gestures to fast app launches, the UI feels polished and modern. OnePlus promises four years of Android updates and six years of security patches  a reassuring commitment for long-term users.

The new “Plus Key” replaces the classic alert slider. It’s customizable to perform specific actions, making it a versatile addition  though longtime fans may miss the iconic switch.

AI features also shine, including voice call transcriptions, automatic content summarization, and the “MindSpace” app that intelligently stores swiped-up data from your screen. The “AI Reframe” tool helps enhance your photos with intelligent composition suggestions.

Connectivity and Audio

On the connectivity front, the OnePlus 13S covers all the bases: 5G, Wi-Fi 7, Bluetooth 6.0, NFC, infrared, and a wide range of satellite positioning systems (GPS, GALILEO, GLONASS, etc.). There’s no 3.5mm jack, but the stereo speakers provide crisp and loud audio that rivals even some of the best in the segment.

Camera System: Capable, But Not Cutting-Edge

The OnePlus 13S features a dual rear camera setup:

• 50MP main sensor (f/1.8, OIS)
  
• 50MP 2x telephoto lens (f/2.0)
  

On the front, there’s a 32MP wide-angle camera that handles selfies and video calls with ease.

While the camera system produces sharp and natural-looking photos, the absence of an ultra-wide or macro lens limits its versatility. Low-light shots are decent, indoor shots shine, and selfies stand out, especially with good skin tones and portrait blur.

That said, dynamic range and detail recovery in shadows could be improved, but these are software-tweakable and may be enhanced via future updates.

Real-World Performance

Real-world usage reinforces the promise of the OnePlus 13S specifications. It scored impressively on benchmark tests  AnTuTu: 2,499,190, GeekBench: 9093, and 3DMark Wild Life Extreme: 6473  keeping up with or even beating larger phones using the same chip. Even with extended gaming sessions, the phone remained cool, which is a testament to excellent thermal management.

Final Verdict: The Best Compact Flagship?

At a starting price of $660, the OnePlus 13S delivers almost everything you’d expect from a high-end phone  except perhaps a more versatile camera system. But if you’re after a powerful, pocket-friendly flagship with cutting-edge performance, excellent battery life, and a display that wows, the OnePlus 13S checks nearly every box.

For those looking to invest in a phone that blends compact design with flagship power, the OnePlus 13S specifications make a compelling argument  and all without burning a hole in your wallet.
