OnePlus has once again raised the bar with OxygenOS 16, unveiled on October 16, 2025. This latest iteration is not just a cosmetic upgrade; it’s a thoughtful combination of AI-driven personalization, smoother performance, refined design, and deeper ecosystem integration. After using it on the OnePlus 13, here’s my hands-on take.
AI-Powered Personalization: Plus Mind & Gemini AI
OnePlus introduces Plus Mind, a personal AI hub that smartly organizes your digital life. By swiping three fingers up, you can instantly save screenshots, notes, and voice memos into a centralized Mind Space.
What makes this stand out is the Gemini AI Assistant. It doesn’t just store data, it understands and analyzes it. For example, if you have notes for a weekend trip, Gemini AI can automatically suggest itineraries, highlight key points from your memos, or even generate a summarized checklist. It’s like having a personal assistant inside your phone that actually remembers your tasks intelligently.

Hands-on experience: The AI felt surprisingly fast and accurate. I tested it with random screenshots and short notes, and the assistant correctly categorized everything in seconds. It feels intuitive, not gimmicky.
Enhanced Voice Recorder
If you often record meetings or lectures, the Voice Recorder app in OxygenOS 16 is a game-changer. It now features automatic transcription, which turns your voice recordings into editable text. Even cooler, it can identify different speakers, making it much easier to reference who said what during long discussions.
Hands-on experience: I recorded a 10-minute discussion and had it transcribed in under a minute. The accuracy was impressive, even with overlapping voices, and the summary feature saved me time scrolling through the whole recording.
Fluid Performance with Parallel Processing 2.0
OxygenOS 16 doesn’t just look smoother, it feels smoother. OnePlus introduced Parallel Processing 2.0, a system-level improvement that starts new animations even before previous ones finish. This results in ultra-fluid transitions, faster app launches, and an overall snappy UI.

Hands-on experience: Scrolling through heavy apps like social media feeds and multitasking between Chrome and YouTube felt buttery. The phone never lagged, and transitions looked natural, not rushed.
Refined Design and Customization
The visual upgrade in OxygenOS 16 is subtle but significant. The UI has a light, airy feel, with Gaussian blur effects and Liquid Glass-like buttons that add depth.
Flux Themes 2.0 takes customization to the next level. You can now have live photo lock screens, animated clocks, and text effects that make the home screen feel alive. It’s personalization without overcomplicating the interface.
Also: Vivo X300 Pro & X300: Dimensity 9500, New Cameras
Hands-on experience: I tried customizing the lock screen with a travel photo and live clock; everything was smooth, and the animations didn’t affect performance. The UI feels modern but remains uncluttered.
Advanced Gaming Features
Gamers will love the enhanced 120FPS support for compatible titles. The Game Assistant tool also received upgrades: you can now control performance settings on the fly, block notifications, and optimize battery usage without leaving the game.
Hands-on experience: Playing a high-frame-rate game like Genshin Impact at 120FPS felt buttery. The Game Assistant overlay is non-intrusive yet powerful, making it easy to tweak performance mid-game.
Seamless Cross-Ecosystem Connectivity
OxygenOS 16 strengthens OnePlus’s ecosystem. You can now share photos between OnePlus and iPhone, sync notifications with Apple Watch, and remotely control your Mac or Windows PC using the O Plus Connect app.

Hands-on experience: I transferred photos from my OnePlus to an iPhone 15 Pro within seconds. Notifications mirrored flawlessly on my Apple Watch, and controlling my laptop remotely was smoother than expected. The ecosystem integration feels thoughtful, not forced.
Improved Security and Privacy
Privacy is a priority in OxygenOS 16. The Private Computing Cloud ensures that sensitive data is processed securely on-device, reducing exposure to external servers. Security patches have been refined, and subtle UI changes reinforce a sense of trust.
Hands-on experience: The privacy settings are easy to navigate, and the OS clearly indicates which apps access sensitive data. You feel in control without being overwhelmed.
Availability
OxygenOS 16 is launching first on the OnePlus 15 and will gradually roll out to older OnePlus devices starting October 17, 2025. Early adopters on the OnePlus 13 will already get a glimpse of its AI-first experience.
