OnePlus 11 New Features & Bugs Fixed Update 2025: OxygenOS 15 Full Review

by

OnePlus 11 and OnePlus 11R users must have been waiting long enough. The iOS 15 Oxygen update based on Android 15 is already spreading, and it is rich in features, repairs, and other novelties. When you are in the mood of smooth operation and intelligent touch-ups, then more than 35 new features and bug fixes make this latest official update the largest one so far of these phones.

This post will be all about what I have observed since upgrading even the slightest details and these improvements will be shared. Take a seat and here is what is inside this considerable update: performance enhancements, the user interface modifications, new tools, and finally, the cure against frequent headaches. Be it with the update on your phone or not, here is everything that you need to know.

Update Overview and Key Details

There is a lot on the table, even in the basic term, with OxygenOS15 to the users of OnePlus 11 and OnePlus 11R, so the first thing will be:

  • Version: 15,0,0,820
  • Size of Update: 1,62 GB
  • OnePlus 11, OnePlus 11R 5G
  • Introduction: phased, over time, in phases–if you have not gotten it yet, watch out!

Android Security:
The update brings both phones to the latest security level of Android 15 and comes with the security patch of May 2025. It translates into more security of your data and more sleep at night.

General Improvements:

  • Minor bugs of the system and other non-essential problems are fixed.
  • The system and user interface (UI) are equally faster and smoother.
  • The whole process of update is fast, despite the size of download.

Not all the people receive the update on the same day. The batch rollout aids OnePlus to overcome the unanticipated bugs and optimize performance to all people. In case you still haven t seen the update, you soon will.

Performance Enhancements Across the System

OxygenOS15 is not all about the new features; rather, it is also about smoothing things out and making things faster. Even the transitions became more smooth and without delays just after I was finished with installing the update.

System Optimizations

What’s better?

  • Opening and closing of the apps is faster.
  • There is the sense of the faster swipe between screens and apps.
  • UI has a better reaction and less stuttering or lag.

Trinity Engine Polish

The update maximizes the Trinity Engine powering resources handling within the system. There are actual benefits:

  • Animations that are less erratic
  • Fewer delays on swapping apps that are heavy in duty
  • Gestures like swipe up/down do work perfectly.

Here’s what improved for me:

  • Rapid opening applications: Application loading is fast and no delays in switching.
  • Stability: I find fewer non-anticipated slows even when a lot of apps are up and running.
  • Smooth swiping: Scrolling and swiping gesture motion are crisp back and smooth

When fluid performance is of concern to you, those essential changes in Oxygen iOS 15 are extremely noticeable. System transition polishing is outstanding, a regular task becomes enjoyable.

New and Improved Features in Oxygen iOS 15

OnePlus has cooked in a long list of new features that are both small and large. The new changes result in a more flexible and enjoyable daily use, whether you prefer personalizing your phone, being a productivity app, or getting greater control over some major aspects.

Clock App Enhancements

The Clock app now works smarter:

  • Stopwatch Live Alerts: Now you can also notice the live notifications when stopwatch is being implemented. This was being the case in the past only with the timer.
  • Alarm Notifications: As your alarm completes its initial ring you are presented with a live notification of the next alarm step immediately, so you do not need to guess whether the alarm will go off again. Keep up with your reminders simple.

Home Screen Customization: Folder Resize

Customizers should be happy! The change is that folder resize comes directly into the launcher:

  • Resize Options: you can select and alter any folder on home screen to 1×2 (vertical) or 2×1 (horizontal).
  • No More Expediency: This used previously had to use an extra launcher APK. It is just working now after update.

It is easy to resize the folders. Drag and choose a size you desire by holding it, and your folders get adjusted.

Contact App Improvements

Managing contacts gets a boost:

  • Now when you add or modify someone in your contact book, you get able to provide a unique ringtone to that individual.
  • This makes anyone identify the caller by the sound alone.

Gesture Mode and Floating Windows Fixes

If you use gesture navigation a lot, this update smooths things out:

  • Close Floating Windows: Windows floating apps now have an option of closing it with gestures which previously did not work all the time.
  • Shadow Effect No more: The bothersome shadow that was around floating apps has been eliminated and the floating windows are smoother and neater.

System Navigation: Circle to Search

  • Circle anywhere on your home screen and your phone will be searched in that region via Google Search.

How to use Circle to Search:

  1. Open Quick settings in Settings System & updates System Navigation.
  2. Circle to Search will become activated.
  3. Tap and hold on your home screen, draw a circle around what you want to search and Google does the rest.

It comes in particularly useful when one needs to get fast information or to find something in an image without keying.

Screen Recording Update

Screen recording is now more flexible:

  • Partial-Screen Capture: Capture only part of what you see on your screen (it already exists with some users; it will become available to others soon).
  • Now full-screen recording is always provided to most people, but partial recording is being introduced.

Wish to know whether you have this feature or not? Begin to start a screen recording and see if can set the recording space. Comment and tell me whether it is in your device.

Bug Fixes and Stability Improvements

It is not about new things anyway what is important are the solutions to those daily frustrations that keep you at slower pace.

Connectivity Fixes

Wi-Fi:

  • Portable a trouble with Wi-Fi disappearing or failing to display because connected under difficult circumstances.
  • Wi-Fi automatically restores connection and the indicator does not vanish now.

Mobile Network:

  • The 5G network problems are minimized.
  • There are no more internet connection roller coasters.
  • The connection by the phone calls is more stable and this matter a great deal in case you change the network frequently or you travel a lot.

Fingerprint Unlock Improvements

  • The fingerprint unlock is quicker than before and the icon now shows up even when the screen is turned off.
  • Your first attempt to unlock your phone will be recognized by the sensor often enough, reducing the number of frustrating unlock failures.

Miscellaneous Bug Fixes

  • Stagnant UI shadows on in-put floating windows.
  • Resolved issues that were caused when gesture controls overlooked or failed to shut down applications.

All these repairs make the phone hold firmly and sound steady and stable in regular usage.

Battery and Charging Performance

All the updates suggest improved battery life, but what is the accurate reality of Oxygen iOS 15? User reviews are mixed one: this is my experience and a couple of tips.

Battery Life

Some positives:

  • Lots of users claim that the battery life is improved after the update.
  • I think system and third-party app battery consumption is reduced.

Some negatives:

  • Some are yet to experience speedy drain happening, mostly in taxing applications.
  • In this case, sometimes waiting till a future update or resetting the phone can help (make sure you first backup your data).

Charging Speed and Heating

  • Most units have become faster to charge.
  • Others including myself felt that they became even warmer when charging. This could be because of the warm weather and it is something to be watched.
  • The phone does not even get hot during normal operation; it usually heats up only when charging.

What if you see battery drain?

  • Restart once the update has been done.
  • In case you continue to experience issues, backup the data and complete a factory hard reset.
  • Be on the lookout of future patches containing additional repairs.

Gaming Performance Enhancements

This OnePlus 11 New Features & Bugs Fixed Update 2025 will delight the gamers with the performance increase.

  • Real Frames Rates: Games are loading quicker and staying at easier frame rate.
  • Consistent performance: When it comes to games, they perform decently even after an extended period, but heat and a slight battery loss are possible.

Normal gaming barely exhibits any hitches or long delays. Even in the extreme case of playing heavily for extended hours all the time, you will still experience some heating or increased battery depletion rates, however, the overall playability is much more acceptable.

Conclusion

OxygenOS 15 on the OnePlus 11 and 11R may be the greatest step the two phones have ever taken. It is not only about something new and new capabilities it also encompasses many small changes, improvements to everything you are already using and little gems that make a great experience.
