TECNO has officially rolled out HiOS 15, its latest Android-based custom operating system, and this time it’s more than just a facelift. Designed with a sharp focus on local relevance, AI integration, and performance optimization, HiOS 15 is TECNO’s biggest attempt yet to deliver a streamlined and intelligent mobile experience—especially for the Indian market.
Whether you’re a student, professional, or first-time smartphone user, HiOS 15 has features that respond directly to the frustrations many budget Android users face today: bloatware, laggy performance, poor privacy controls, and a lack of localized functionality.

What’s New in TECNO HiOS 15?
The new HiOS 15 update introduces significant improvements in five major areas: reduced bloatware, AI-powered functionality, local language support, offline tools, and enhanced privacy features.
Leaner Software Means Faster Phones
40% Reduction in Pre-Installed Apps
One of the standout features of HiOS 15 is TECNO’s bold move to cut bloatware by 40%. Pre-installed apps are a frequent complaint among smartphone users, especially in the budget category. With fewer unnecessary apps hogging storage and memory, users can expect a smoother, faster performance right out of the box.
Enhanced System Responsiveness
HiOS 15 isn’t just lighter—it’s smarter under the hood. TECNO has optimized the core with features like:
-
Memory Defragmentation for smoother data access
-
Improved animation engine for fluid navigation
-
MemFusion 3.0, TECNO’s RAM expansion technology, allowing background support for over 25 apps without slowdowns
This combination ensures multitasking feels effortless, even on entry-level devices.
AI-Powered Smart Assistant That Speaks Your Language
Introducing the New Ella Assistant
TECNO’s Ella voice assistant has been re-engineered with Indian users in mind. Now supporting Hindi, and with future updates for Tamil, Bengali, Gujarati, and Marathi, Ella offers more than basic commands.
Powered by India-specific AI models like Sarvam AI, Ella understands the way Indians speak—not just the words, but the local dialects and context.
What Can Ella Do?
-
Summarize phone calls in real-time
-
Transcribe WhatsApp calls
-
Auto-answer calls with short summaries when you’re unavailable
-
Offer hands-free control for daily tasks like reminders and messages
These features are especially valuable in a country where voice-first communication is dominant across regions and age groups.
Offline AI Tools for Photos and More
Internet connectivity isn’t always reliable—especially in rural or semi-urban parts of India. Recognizing this, TECNO added offline AI tools to HiOS 15 that bring high-end features without the need for a data connection.
AI Image Editing Without the Cloud
HiOS 15 introduces several impressive offline AI photo editing tools:
-
AI Eraser – Remove unwanted objects from images
-
Image Extender – Expand photos beyond their original boundaries
-
Image Sharpener – Fix blurry or unclear images
These tools are processed locally, meaning users don’t have to upload anything to the cloud—faster, safer, and more convenient.
Smarter Privacy and Refined UI Features
Screenshot Blurring and Data Protection
HiOS 15 steps up privacy with built-in intelligence:
-
Auto-blur sensitive data in screenshots (like OTPs or contact numbers)
-
Smarter notification management for cleaner, more secure alerts
These updates are part of TECNO’s commitment to ensuring user privacy without complicating the experience.
UI Improvements You’ll Notice
-
Picture-in-Picture (PiP) support for multitasking
-
Revamped icons and layout for a more modern feel
-
Faster notification response times, ensuring less delay and clutter
Together, these features enhance the overall usability and fluidity of the system.
