OxygenOS 15 Review: Battery Backup, Camera, Performance & General Stability – OnePlus’s Big Comeback

The latest stable release of OxygenOS 15 for the OnePlus 12 has caught the attention of many tech enthusiasts and OnePlus users alike. The update brings a slew of enhancements focused on improving battery performance, network stability, and multitasking, setting the stage for a more polished OnePlus experience. In this article, we’ll delve into the performance, battery life, gaming capabilities, and camera quality, based on extensive testing and firsthand experience.
Stability and Performance: A Refined Experience
OxygenOS 15 shows significant improvements in stability across various connectivity options. In my tests, I found no issues with Wi-Fi or Bluetooth, which had posed intermittent problems in previous versions. Mobile data stability also stood out, particularly 5G, which remained strong throughout my usage. I noticed better RAM management in this release as well; most apps stayed active in the background, minimizing reload times and enhancing multitasking.

Fingerprint responsiveness has also been optimized, unlocking the device instantly without delays. Animations, which previously suffered from occasional lag, now feel smoother and more refined.

Battery Life: Consistency in High-Performance Mode
One of the standout improvements with OxygenOS 15 is the battery management, which remains reliable even in high-performance mode. Across several test cycles, screen-on time averaged around 7 hours with standard usage. For heavy gaming sessions, particularly with BGMI (Battlegrounds Mobile India) at 90 FPS and screen recording enabled, the OnePlus 12 managed a commendable 4+ hours of continuous gameplay while maintaining around 20% battery at the end.

Overnight battery drain, another key area, has also been well-optimized. During idle hours, the battery drain remained low, around 3% on average, making OxygenOS 15 a dependable choice for users needing solid standby time.
Gaming: Enhanced 90 FPS Performance
For gaming enthusiasts, OxygenOS 15 makes an appealing case. Playing BGMI at 90 FPS with screen recording turned on was smooth and enjoyable. Frame drops were minimal, providing a steady gaming experience, especially in TDM (Team Deathmatch) mode, where FPS held between 90 and 91 with slight dips during intense scenes. Classic matches showed minor fluctuations but overall delivered a satisfying gameplay experience, handling high-action scenarios well.

The update also introduces native support for 90 FPS screen recording while gaming, a noteworthy addition for those who enjoy recording their gaming moments. Although the device did experience temperature increases during extended sessions, stability and gameplay remained unaffected.

Camera: Minor Improvements, But Room for More
Despite substantial enhancements across other features, the camera segment received only minor adjustments. A new live photos option is available, but overall, the camera quality remains similar to that of OxygenOS 14. Photos taken in well-lit environments retain accurate colors, solid dynamic range, and clear details, while indoor shots display slight noise in low light.

Portraits capture subjects with accurate edge detection and natural background blur. The primary lens performs consistently well, though there’s a need for slight refinements, particularly in selfie and low-light conditions, to meet expectations for users who rely on their camera frequently.

Addressing User Feedback
OnePlus has been receptive to user feedback in this update. For example, Wi-Fi and Bluetooth stability issues, which users had highlighted in previous versions, are noticeably improved. Additionally, users who encounter lag or performance concerns can now use the OnePlus phone manager app to optimize the device, clearing caches and making necessary tweaks. For those upgrading from an older Android version, a factory reset is recommended to ensure optimal performance.
Final Thoughts
OxygenOS 15 represents a well-rounded, optimized update for OnePlus 12 users, addressing previous concerns while offering new features that enhance daily usability. Its emphasis on stability, battery management, and gaming performance highlights OnePlus’s commitment to quality and user satisfaction. Although there’s still room for improvement in the camera department, the overall experience is polished and reliable, making OxygenOS 15 a recommended upgrade for OnePlus users.
Whether you’re a gamer, a multitasker, or someone seeking a stable daily driver, OxygenOS 15 brings enough to the table to make it worth the update.
