The stable version of OxygenOS 15 has officially rolled out for the OnePlus 12, bringing several improvements and a few minor issues. Let’s dive into a detailed review of this new update, covering its stability, battery performance, gaming capabilities, and more.
System Stability and General Improvements
Users have reported noticeable improvements in system stability. Key features like Wi-Fi, Bluetooth, and 5G connectivity have become more reliable. For instance:
Wi-Fi Disconnections Resolved: An issue from OxygenOS 14, where Wi-Fi would disconnect has been fixed.
Fingerprint Reliability: The under-display fingerprint scanner now works seamlessly with a single tap.
RAM Management: Most apps remain active in the background without unnecessary reloads.
Animations are smoother, and no significant bugs were reported except for two minor issues:
- Always-On Display: Occasionally turns off even when enabled.
- App Compatibility: Some older apps, like FPS measurement tools, are not yet optimized for Android 15.
Battery Performance
The battery life has seen improvements, with users achieving around 7 hours of screen-on time under basic usage in high-performance mode. Even with heavy tasks like BGMI gaming at 90 FPS, the OnePlus 12 offered around 4.5 hours of continuous gameplay with 23% battery remaining.
Overnight battery drain is minimal, with only 3% lost when the device is idle. Users experiencing issues with battery life are advised to:
- Perform a factory reset after updating.
- Use the Phone Manager app to clear the cache and optimize the device.
Gaming Performance
Gaming has significantly improved on OxygenOS 15. The OnePlus 12 now supports screen recording while gaming at 90 FPS, which is a big win for gamers. Testing with BGMI revealed:
Stable FPS during most scenarios, dropping only in action-heavy moments like hot-drop areas.
Smooth performance in classic matches and TDM, with FPS fluctuating between 70 to 91 in challenging environments.
However, benchmark tests showed some heating issues, with the device warming up during prolonged stress tests, though this didn’t heavily impact gaming sessions.
Camera Performance
While the camera remains good, there are no significant improvements over OxygenOS 14.
Primary Camera: Delivers sharp details, accurate colors, and good dynamic range in well-lit environments.
Low-Light Performance: Decent, though some noise is present in darker settings.
Selfies: Capture natural tones with balanced highlights and shadows, though edge detection in portrait mode could be improved.
A new Live Photos feature has been added, but there are no other major upgrades.
Additional Features and User Queries
Rounded Icons: Achievable using the default settings or by applying the Radiance Icon Pack.
Photo Editing Features: Currently, there’s no option to copy edits from one photo to another.
OTA Update Delays: Updates are being rolled out in stages and may take a few weeks to reach all users.
Conclusion
OxygenOS 15 is a solid update for the OnePlus 12, bringing better stability, gaming enhancements, and smoother animations. The main drawbacks are the lack of significant camera improvements and minor heating issues during benchmarks.
For OnePlus 12 users, this update is highly recommended. If you’re experiencing issues, try the suggested fixes or share your feedback for future updates.
