Performance Enhancements
I’ve noticed smoother performance right away after installing this update. The OnePlus team has put in work on system optimization, making the UI faster, more stable, and more pleasant to use.
Speed and Animation Boost
- Faster app launch: Apps open and close more quickly, with reduced lag between taps and app responses.
- Stable gestures: Swiping through screens and using home gestures feels smoother, and the animations look more refined.
- Reduced bugs: Those odd small bugs and UI freezes that annoyed me before are mostly gone.
Trinity Engine Upgrades
The Trinity Engine has received tweaks that make interactions more consistent and responsive. Many users will notice:
- Better animation stability: App opening/closing and swiping effects are now more consistent.
- Minimal lag: UI transitions are almost instant, making the device feel snappier.
What changed?
- Faster unlocking and switching between apps.
- More reliable multitasking with split-screen or floating windows.
- Less likelihood of animation jank or stutter during fast navigation.
The overall effect feels like the phone just got a fresh burst of speed.
New and Improved Features
There are many new features in OxygenOS 15 and Android 15. Some changes you’ll stumble upon yourself, but others are hidden or require a little probing. Here are the standout feature updates and how they work.
Clock App Enhancements
- Live Alerts for Stopwatch:
You now get live notifications when you run the stopwatch, not just for timers. Before, only the timer would push a live alert, but now even when you’re timing a workout or tracking activity, you get easy-to-read status updates in your notification tray. - Alarm Live Alert Notifications:
When you set an alarm, your phone will now show a live alert as soon as the first step is done. If you snooze or dismiss the alarm, you’ll get another live alert for the next scheduled alarm, helping track your routines better.
Home Screen Customization
- Folder Resizing:
I’ve always wanted more flexibility in managing home screen folders, and this update finally adds it. Now you can:- Resize any app folder to 1×2 (vertical) or 2×1 (horizontal)
- Arrange icon layouts however you want
- Previously, you needed a separate system launcher APK for this trick. Now it works right out of the box.
Contact App Improvements
- Custom Ringtone for Each Contact:
Adding or editing a contact now lets you pick a unique ringtone. This way, I can instantly know who’s calling just by the sound.
Gesture Mode Fixes
- Floating Window Gestures:
Previously, closing floating window apps with gestures was hit-or-miss. Now, the system recognizes your swipe and closes these mini apps every time. - Shadow Effect Fixed:
Those odd-looking shadows appearing around floating windows are now gone, which makes the visual presentation cleaner.
System Navigation Update
- Circle to Search:
A highlight of this update! Now, from the home screen, I can tap and draw a circle anywhere to search with Google for anything in that area. It feels natural and saves a ton of time. How to Use Circle to Search:- Long-press on any spot on your home screen.
- Draw a circle over the area or app you want to search about.
- Google instantly searches for the selected content.
Screen Recording Update
- Partial Screen Recording:
Some users now see an option to record just a section of their screen (not available for everyone yet). You can select and record a specific window or area, which is much more focused than recording the full screen.- I didn’t get this feature on my model yet, but several others report it’s live for them.
Let me know in the comments if partial screen recording has rolled out to you!
Bug Fixes and Stability Improvements
This update focuses on squashing stubborn bugs for real improvements in daily use. The fixes touch key areas: Wi-Fi, mobile networks, fingerprint unlock, and the user interface.
Connectivity Fixes
- Wi-Fi Stability:
Fixed instances where Wi-Fi would disconnect by itself or the Wi-Fi icon would suddenly disappear, leaving you toggling airplane mode or restarting the device. Now Wi-Fi stays reliably connected and visible. - Mobile Network Reliability:
Improved 5G and overall signal stability. Earlier, the network bar would jump up and down, or calls would struggle to connect. The update straightens out network hiccups for smoother calls and more consistent 5G.
Fingerprint Unlocking
- Faster, more accurate unlocking: The fingerprint icon appears instantly even when the screen is off.
- The recognition is sharper—place your finger, and the phone unlocks in an instant.
- Previously, unlocking on the first try could be tricky, or the icon would be slow to show; now both are much improved.
Other UI and Gesture Fixes
- Floating window shadow glitches are gone.
- Swipe gestures correctly recognize your motion every time, especially for closing pop-ups or floating windows.
Battery and Charging Performance
If battery life is important to you (and let’s be honest, who doesn’t care about it?), here’s my honest take after using the new update.
Mixed Battery Life Reports
- Positive: Some users see real improvements in battery backup. Standby times have increased, and daily use drains less power, especially from system and third-party apps.
- Negative: Others still find the battery draining quickly, with the update not helping much.
- My own experience: I’m in the “improved” group. If you’re not, give your phone some time. Sometimes, after a big update, battery stats stabilize after a few charge cycles.
Tip: If you still face battery drain, consider a factory reset (but only after backing up your data). This helps clear out old bugs and refreshes system files. Wait for a future patch if things don’t improve.
Charging Speed and Heating
- Charging is faster than before. Plugged in, the phone charges up quickly—just what I want from a flagship.
- Heat warning: Charging does cause the device to get warm, especially during the summer season. In my case, the extra warmth only shows up when plugged in and charging, not during normal use.
Tip: Give your phone a break if it feels too hot, and don’t cover it with thick cases while charging.
What to Do if You See Battery Drain
- Restart your phone and allow it some days post-update.
- If all else fails, try a full backup and reset.
- Keep an eye out for future patches, since OnePlus tends to fix battery drain in follow-up updates.
Gaming Performance Enhancements
Mobile gamers will notice the upgrade right away. Before, games could stutter, lag, or suffer frame drops, especially during longer sessions. After the OxygenOS 15 update:
- Improved frame stability means smooth, uninterrupted gameplay even on graphics-heavy titles.
- Bugs causing games to jitter or skip frames are now fixed.
- Quick switching between games and background apps is smoother, boosting the experience.
However, prolonged gaming does lead to some heating and battery drain, just like before. In regular sessions, though, the device holds up well and avoids lag or overheating.
Conclusion
The OxygenOS 15 (Android 15) update for OnePlus 11 and 11R adds a lot more than just a version bump. From smoother animations and clever new search gestures to better clock, contact, and navigation features, it’s a big step forward. Bug fixes around Wi-Fi, mobile networks, fingerprint unlock, and battery performance help restore confidence in your phone’s daily reliability.
