Full OnePlus 13 review covering design, performance, OxygenOS 15, camera tests, battery life, and whether it still deserves the “Flagship Killer” title in 2025.

Introduction

For years, OnePlus was known as the “flagship killer” brand — delivering premium specs at affordable prices. But in 2025, with the launch of the OnePlus 13, things have changed.

Packed with the latest Snapdragon 8 Gen 4 chip, a 2K OLED display, and OxygenOS 15, the OnePlus 13 promises flagship-level performance at a lower price than rivals like the iPhone 16 Pro Max and Samsung Galaxy S25 Ultra.

But is it really a killer deal — or has OnePlus drifted into overpriced flagship territory? Let’s dive into our full review.

Design & Build Quality

  • Material: Polished aluminum frame with Gorilla Glass Victus 3 front and back.

  • Colors: Glacier White, Obsidian Black, and Jade Green.

  • Weight & Size: 198 grams, making it lighter than most flagships.

  • Durability: IP68 water/dust resistance, finally standard on OnePlus flagships.

💡 Unique Touch: The iconic alert slider remains, a fan-favorite feature missing in many rivals.

✅ Verdict: Sleek, lightweight, and premium — OnePlus has refined the minimalist look.

Display & Visual Experience

  • Size: 6.7-inch LTPO 4.0 AMOLED display.

  • Resolution: QHD+ (3216 × 1440).

  • Refresh Rate: Adaptive 1–144Hz for smooth scrolling and gaming.

  • Brightness: 2600 nits peak, brighter than Pixel 10 Pro but shy of Galaxy S25 Ultra.

  • Features: Dolby Vision + HDR10+ support.

📱 Experience: Razor-sharp resolution, vibrant colors, and fluid animations — excellent for streaming, gaming, and everyday use.

✅ Verdict: One of the best displays in the segment, though Samsung still leads in brightness.

Performance: Snapdragon 8 Gen 4 + OxygenOS 15

  • Processor: Qualcomm Snapdragon 8 Gen 4.

  • RAM & Storage: 12GB/16GB RAM, storage options from 256GB up to 1TB (UFS 4.1).

  • Software: OxygenOS 15, based on Android 15, with a clean and fast UI.

Benchmark Results:

  • Geekbench 6: 3,150 single-core / 10,200 multi-core

  • 3DMark GPU Score: Comparable to Galaxy S25 Ultra.

  • Gaming Test: Runs Genshin Impact at 144fps with no stutter.

✅ Verdict: Blazing-fast and smooth. Performance is flagship-level, but software optimization makes it feel snappier than Samsung.

Camera Review: Still Catching Up?

The triple-camera setup on the OnePlus 13 is solid but not industry-leading.

  • Main Camera: 50MP Sony IMX sensor with OIS.

  • Ultra-Wide: 48MP with 120° FOV.

  • Telephoto: 32MP with 5x optical zoom.

  • Front Camera: 20MP selfie shooter.

Camera Features:

  • Hasselblad color calibration for true-to-life colors.

  • AI Video Mode with stabilization.

  • Nightscape 4.0 for better low-light shots.

  • Pro Mode with RAW support.

📸 Comparison:

  • Better than previous OnePlus phones — more natural colors and less over-sharpening.

  • Falls short against the iPhone 16 Pro Max and Pixel 10 Pro in low-light and portrait photography.

  • Zoom is weaker than the Galaxy S25 Ultra’s 10x periscope.

✅ Verdict: A good camera for most users, but not the best in 2025.

Battery Life & Charging

  • Battery Size: 5,200mAh.

  • Charging:

    • 100W SUPERVOOC wired charging (0–100% in 25 minutes).

    • 50W wireless charging.

    • Reverse wireless charging support.

Endurance Test:

  • 1.5–2 days of moderate use.

  • 9 hours of screen-on time during heavy usage.

✅ Verdict: One of the fastest charging flagships in 2025. Perfect for users who hate waiting for a recharge.

Software & Features (OxygenOS 15)

OnePlus has polished OxygenOS 15 into one of the cleanest Android skins:

  • AI Smart Gallery: Auto-tags and edits photos.

  • AI Voice Notes: Records and transcribes meetings in real time.

  • Always-On Display Themes with more customization than Pixel or iPhone.

  • Zen Mode 3.0: Helps reduce screen addiction.

✅ Verdict: Simple, smooth, and customizable — OxygenOS remains a fan favorite.
