OnePlus 13S Review: The Flagship Killer Evolves Again — Or Just Another Speed Demon?

OnePlus has long been known for its “Never Settle” philosophy — and the 13S is the latest attempt at redefining value in the premium segment. It’s bold, fast, sleek — and packed with specs that rival flagships twice its price.

But the question is: Is the OnePlus 13S just about brute speed and charging… or does it offer a well-rounded flagship experience?

Let’s break it down: performance, design, camera, software, AI features, gaming, battery — the full package.

1. Design & Build: Modern, Minimal, and Distinctively OnePlus

The OnePlus 13S brings a premium finish and updated design language, while staying true to its clean aesthetics.

• Flat-edge design with gentle curves on the back – feels great in hand
• Matte-frosted glass back – resists fingerprints beautifully
• Polished aluminum frame – solid and flagship-grade
• IP65 rating – splash-proof, though not fully water-resistant like IP68
• Weight: 207g – feels solid but not heavy
• Color Options: Obsidian Black, Glacier Blue, and Jade White

Verdict: Clean, bold and functional — OnePlus didn’t reinvent the wheel, but they’ve refined it.

2. Display: Bright, Bold & Super Smooth

OnePlus continues its excellence in display tech — the 13S features a top-tier AMOLED panel.

• 6.78″ 1.5K AMOLED LTPO
• Resolution: 2780 × 1264
• Refresh Rate: 1Hz–120Hz adaptive
• Brightness: 4500 nits peak (Auto HDR)
• HDR10+, Dolby Vision support
• ProXDR: Enhanced dynamic range in photo preview and gallery

Real-World Experience:

• Colors are punchy but not cartoonish
• Visibility in sunlight is excellent
• Adaptive refresh is seamless – buttery scrolling

Verdict: Easily one of the brightest and most responsive displays under ₹80,000.

3. Performance: Snapdragon 8 Gen 3 — The Beast Unleashed

If raw performance is your thing, the OnePlus 13S is here to impress.

• SoC: Snapdragon 8 Gen 3 (4nm)
• RAM: 12GB / 16GB LPDDR5X
• Storage: UFS 4.0 (256GB / 512GB)
• Geekbench Multi-core: ~7200+
• AnTuTu Score: 1.7 Million+

Real Life Usage:

• Zero lag even in heavy multitasking
• CapCut, Lightroom, video rendering – no sweat
• AI-assisted system performance feels more adaptive and fluid than previous OnePlus phones

Thermals: Vapor chamber cooling = cool and consistent performance even in long sessions

Verdict: Fast, smooth, and future-ready – this is flagship-grade speed at a mid-flagship price.

4. Camera: Gets the Job Done — With Room to Grow

OnePlus has improved its camera game, especially in daylight — but it still can’t match Google or Samsung’s software magic.

Camera Setup:

• 50MP Sony LYT-808 primary (OIS)
• 8MP ultra-wide
• 2MP macro (unnecessary, honestly)
• 16MP selfie camera (f/2.4)

Camera Experience:

• Daylight: Excellent detail and dynamic range, natural colors
• Portraits: Edge detection good, background blur is decent
• Night Mode: Much improved, but sometimes oversharpened
• Video: 4K 60fps is stable, with good detail and colors
• AI Features: Scene optimization, skin tone tuning, and Smart HDR

Missing: No telephoto lens — limits flexibility.

Verdict: Great primary camera, but secondary sensors and AI tuning still trail behind Pixel and Galaxy.

5. Gaming: Speed + Smoothness = Gamer’s Delight

The OnePlus 13S is a gaming powerhouse, and it knows it.

Real Game Test:

• COD Mobile: Max Graphics + Max FPS = buttery smooth
• Genshin Impact: High preset @ 60fps — holds steady with minor frame dips
• BGMI/PUBG: HDR + Ultra – Gyro accuracy is excellent
• Asphalt 9: No lag, great visuals

Benchmarks:

• Touch Response: 1000Hz polling rate – ultra-responsive
• Haptics: Sharp, precise, very immersive
• Gaming Mode: Game Tools with performance toggle, FPS monitor, voice changer etc.

Verdict: One of the best phones for gaming under ₹80K.

6. Battery: Big, Fast, and Reliable

• Battery: 5400mAh
• Charging: 100W SUPERVOOC (wired), 50W AIRVOOC (wireless)
• Backup:
  • Mixed Use SOT: 8–9.5 hours
  • Gaming (1 hour): ~15% drain
  • Streaming: ~6%/hour

Charging Speed:

• 0% to 100%: ~27 minutes (wired)
• 50W wireless: ~50–55 mins

Verdict: Charging this fast still feels like magic — a clear win over Pixel or iPhone.

7. Software & AI Features: Clean, Fast — But Less Smart Than Pixel

• OS: OxygenOS 14 (Android 14)
• AI Tools:
  • Smart Suggestions in Gallery & Notes
  • OnePlus Notes AI summary
  • Device search with AI ranking
  • New “Trinity Engine” – improves app launch, background hold, and RAM efficiency

Software Experience:

• Clean UI (though not as bloat-free as Pixel)
• Fast animations, zero ads
• 4 years OS + 5 years security updates

Verdict: OxygenOS is smooth, clean, and closer to stock — but the AI is still in early stages.

8. Connectivity, Audio & Biometrics

• Stereo Speakers: Loud, balanced, good bass
• Wi-Fi 7, Bluetooth 5.4, NFC
• IR Blaster: Yes
• In-display fingerprint: Super fast
• Face Unlock: Works fine, even in low light

Verdict: Covers all the connectivity needs — no major compromise.

11. Who Should Buy the OnePlus 13S?

Perfect if you:

 Want flagship-level performance at a lower price
 Game regularly and want low-latency + high FPS
 Love fast charging and long battery life
 Prefer clean UI without ads
 Want a well-rounded, no-nonsense flagship

But maybe skip if you:

Final Verdict

The OnePlus 13S is a true flagship killer — not just in name, but in experience.

It doesn’t try to be the smartest or most artistic phone. But for performance, battery, gaming, display, and sheer value, it’s hard to beat.
