1. Gaming Performance (Snapdragon 870)

  • Benchmark Scores (An Tu Tu v9): ~700,000 (similar to POCO F4 GT, IQOO Neo 6).
  • Real-World Gaming:
  • Gen shin Impact (High Settings): ~50-55fps (dips in long sessions).

  • n1/n3/n28/n41/n78 (no mm Wave).
  • Real-world speed: ~600Mbps on JIO 5G (NSA).
  • Wi-Fi 6: Max throughput 1.2Gbps (vs 1.7Gbps on Snapdragon 888 phones).
  • Bluetooth 5.1: Stable with TWS earbuds (but no dual-device pairing).

4. Long-Term Durability (2+ Years Later)

8. Should You Still Buy It? (2024)

  • Buy if:
    • You’re a MODDER who loves custom ROMs.
    • Need 65W charging + AMOLED under ₹20K.
  • Avoid if:
    • You care about Android 14+ or camera quality.

1. Display Secrets: Beyond Specs

  • True Refresh Rate Behavior:
    • Hidden 90Hz Mode: Enable via ADB (settings put global one plus_ screen_ refresh _rate 90). Smoother than 60Hz, saves battery vs 120Hz.
    • PWM Flicker Fix: Use DC Dimming (in settings) to reduce eye strain, but crushes blacks slightly.
  • Touch Sampling Rate:
    • 240Hz normal, 480Hz in gaming mode (beats Pixel 7a’s 120Hz).

True Refresh Rate Behavior

2. Battery & Charging: Hidden Limits

  • Actual Charging Speed:
    • 0-50% in 12 mins, but last 10% takes 8 mins (curbing heat).
    • Warp Charge 65W works ONLY with OEM charger (even 100W PD chargers max at 18W).
  • Battery Saver Hacks:
    • “Suspend execution for cached apps” (in Developer Options) reduces background drain.
    • Dark Mode + 1080p resolution saves ~8% battery vs QHD emulation.

3. Camera: G Cam vs Stock Showdown

  • OnePlus 9R Mobile Stock Camera Tricks:
    • Pro Mode RAW has 12-bit depth (vs 10-bit on Pixel 6).
    • “Ultra Shot” HDR Algorithm: Pulls shadows better than Samsung’s Scene Optimizer.

4. Performance: Kernel & Root Tweaks

  • Best Custom Kernel: Radioactive Kernel (v11.5).
  • CPU Under volt: Saves 5-7% power with no performance loss.
  • GPU OC to 905MHz (from 670MHz)—gains 15% FPS in Gen shin Impact.
  • Debloating Guide: Remove OnePlus bloat without root:

5. Hardware Teardown: Upgrade Potential

  • Thermal Paste Mod: Replacing stock paste with Thermal Grizzly KRYONAUT drops temps by 4-6°C.
  • Storage Speed Test:
    • Seq. Read: 1800 MB/s (UFS 3.1), but random 4K lags vs iPhone 13’s NVME.
    • Haptics Upgrade: Flash OnePlus 9 Pro’s motor driver via EDL for stronger feedback.

6. Network Hacks: 5G & Beyond

  • Force LTE CA (Carrier Aggregation):
