The OnePlus 15 is more than just a flagship smartphone with powerful hardware and premium cameras. Running the latest version of OxygenOS, it includes numerous hidden features that many users overlook. While the impressive display, fast processor, and excellent battery life receive most of the attention, it's often the software features that make everyday use faster, smarter, and more enjoyable.From AI-powered tools and customization options to gaming enhancements and privacy controls, the OnePlus 15 offers a range of features that can significantly improve your smartphone experience. If you've recently purchased the device or are planning to upgrade, these hidden features are worth exploring.Here are some of the best hidden features of the OnePlus 15 you should try.
Customize the Always-On Display
The Always-On Display offers much more than simply showing the time.The OnePlus 15 allows users to personalize the Always-On Display with different clock styles, colours, wallpapers, and widgets. You can also display useful information such as weather updates, battery status, calendar reminders, and notifications without unlocking the phone.This simple customization makes the device feel more personal while providing quick access to important information throughout the day.
AI Writing Assistance
One of the standout software additions is AI-powered writing assistance.Whether you're replying to emails, sending messages, or creating social media captions, the AI tools can help improve grammar, rewrite sentences, summarize text, and suggest better wording.Instead of switching between different apps, these features work directly within supported applications, helping users save time while communicating more effectively.For students and professionals, this feature quickly becomes part of the daily routine.
Smart Sidebar
The Smart Sidebar is one of OxygenOS's most practical hidden features.A quick swipe from the side of the screen opens shortcuts to your favourite apps, screenshots, file sharing, notes, and productivity tools.Instead of constantly returning to the home screen, frequently used functions remain only a swipe away.This significantly improves multitasking and everyday efficiency.
Enhanced Split-Screen Multitasking
The OnePlus 15 makes multitasking easier than many users realize.Split-screen mode allows two compatible apps to run simultaneously. You can browse the web while taking notes, watch videos while chatting with friends, or review documents while replying to emails.The large display provides enough space for both applications to remain comfortable to use.For productivity-focused users, this feature can greatly improve workflow.
Hidden Gaming Features
The OnePlus 15 includes a dedicated gaming mode packed with useful options.Game Mode automatically optimizes CPU performance, minimizes background activity, blocks notifications, and improves touch responsiveness during gameplay.Users can also monitor system performance, frame rates, and temperatures while gaming.These hidden gaming tools help deliver smoother gameplay without requiring manual adjustments every time.
Private Safe
Privacy is becoming increasingly important.The Private Safe feature allows users to securely store sensitive photos, videos, documents, and files behind biometric authentication.Important personal information remains hidden from normal file browsing, providing an extra layer of security.It's especially useful for work documents, identification files, and private photos.
App Lock
The App Lock feature provides additional protection for individual applications.Instead of securing only the entire phone, users can require fingerprint or facial authentication before opening selected apps.Messaging applications, banking apps, photo galleries, and social media platforms can all receive their own layer of security.This helps protect personal information even if someone briefly borrows your phone.
Smart Charging Features
Battery health is often overlooked until performance begins to decline.The OnePlus 15 includes intelligent charging features that learn your charging habits and reduce battery wear over time.Rather than charging to full capacity immediately, the phone can pause charging overnight and complete the final percentage shortly before your usual wake-up time.This helps extend battery lifespan while maintaining everyday convenience.
AI Photo Editing
Photo editing becomes much easier with built-in AI tools.The OnePlus 15 allows users to enhance images, remove unwanted objects, improve lighting, sharpen details, and optimize colours with minimal effort.These intelligent editing features reduce the need for third-party editing software.Even casual photographers can create impressive results directly from the Gallery app.
Live Translation
For users who communicate internationally, Live Translation is an incredibly useful feature.Supported conversations, messages, and selected text can be translated quickly without leaving the current application.Whether travelling, studying, or working with international clients, this feature simplifies communication considerably.
Flexible Screenshot Tools
Taking screenshots involves much more than pressing two buttons.The OnePlus 15 includes scrolling screenshots that capture entire webpages, conversations, or documents.Users can also immediately crop, annotate, blur sensitive information, and share screenshots directly after capturing them.These built-in editing tools save considerable time.
Gesture Navigation
Gesture navigation creates a cleaner and more immersive interface.Instead of traditional navigation buttons, users can swipe naturally to return home, switch applications, or go back.Once learned, gesture navigation becomes faster than conventional controls while maximizing available screen space.The experience feels smoother throughout the operating system.
Zen Mode
Modern smartphones can become distracting.Zen Mode encourages users to disconnect temporarily by limiting phone access for a chosen period.During this time, unnecessary applications remain unavailable, allowing users to focus on work, study, exercise, or simply relax.It's a surprisingly effective feature for improving digital wellbeing.
Hidden Display Customization
The OnePlus 15 offers several display settings that many users never discover.Colour profiles can be adjusted to suit personal preferences, refresh rates can be optimized for battery life or smoothness, and eye comfort settings reduce blue light during evening useThese small adjustments improve both visual comfort and overall user experience.
Quick Launch Shortcuts
The in-display fingerprint sensor offers more than fast unlocking.After unlocking, users can hold their finger briefly to access customizable shortcuts such as the camera, voice recorder, QR scanner, calculator, or favourite applications.This hidden feature saves several taps throughout the day and quickly becomes one of the most convenient tools available.
