The idea of a modular smartphone has always been in the imagination of tech fans — the idea of a phone that can be personalized and evolve with you. HMD Global, under its Nokia heritage, did just that with the original HMD Fusion. Then, fresh leaks indicate that its successor, the HMD Fusion 2, may push the idea to a new dimension. With improved hardware, better design, and next-gen modular accessories called Smart Outfits Gen 2, this next device may re-imagine what a modular smartphone in 2025 can do.

Let’s dissect all that has leaked about the HMD Fusion 2, from its main specs, features, enhancements, and what makes it different.

A New Generation of Modular Smartphones

The first HMD Fusion awed technology fans with its innovative Pogo Pin design that enabled users to plug in modular attachments, referred to as “Smart Outfits.” The concept was direct but useful — users could snap on additional modules like a wireless charging dock, speaker, or a gaming grip to augment the phone’s features.

With the Fusion 2, HMD seems to be doubling down on that concept. The company, according to various reports from NotebookCheck and Moneycontrol, has created a Pogo Pin 2.0 interface to enhance connection stability and module performance. The upgrade should make data transfer faster and power delivery more reliable between the phone and its attached modules.

The new Smart Outfits Gen 2 series is said to feature creative accessories like a Smart Projector Outfit, Camera Grip, Speaker Module, and Wireless Charging Outfit. These modular attachments may turn the Fusion 2 into an extremely flexible tool for content creators, gamers, and busy professionals.

But initial reports also tell us that Smart Outfits Gen 1 modules won’t be compatible with the new device because of pin layout changes. That’s a letdown for first-gen Fusion users, but it also indicates HMD is striving towards superior performance and flexibility in its mod ecosystem.

Performance: Snapdragon 6s Gen 4 for Smooth Efficiency

Under the hood, the HMD Fusion 2 should have the Qualcomm Snapdragon 6s Gen 4 processor — a significant improvement from the first-generation Fusion’s Snapdragon 4 Gen 2. The chipset should provide improved multitasking, enhanced power efficiency, and a more seamless overall performance.

This update puts the Fusion 2 firmly in the upper mid-range category, with phones from companies such as Samsung, OnePlus, and Xiaomi on similar or slightly more premium processors. Paired with clean, close-to-stock Android software (a signature of HMD’s products), the user can expect a seamless experience for daily use, gaming, and media consumption.

Although RAM and storage availability are yet to be officially confirmed, the HMD Fusion 2 leaks indicate that they will start from 8 GB RAM and 128 GB storage, while top-of-the-line models may be possible.

Display: 120 Hz OLED Panel for a Premium Experience

One of the largest improvements over its predecessor is in the display. The Fusion 2 will apparently feature a 6.58-inch Full HD+ OLED display with a 120 Hz refresh rate, which is an improvement from the original’s 90 Hz LCD screen.

This represents a huge jump in both display excellence and smoothness. Consumers can look forward to richer colors, darker blacks, and smoother touch response — perfect for gaming, streaming, or just ordinary scrolling. The transition to OLED also implies improved power efficiency and enhanced sunlight legibility.

For a brand that’s long stood as practical over flashy, this is an attractive move towards a more upscale experience.

Cameras: 108 MP Primary Sensor + 8 MP Ultra-Wide

Camera performance is another space where HMD seems to be playing an upgrade here. The Fusion 2 will sport a dual-camera setup at the back — topped by a 108 MP primary sensor featuring Optical Image Stabilization (OIS), along with an 8 MP ultra-wide lens.

If these specs hold true, this would be a serious upgrade over the previous model’s mid-range camera system. The use of a high-resolution sensor should translate to sharper images, better low-light performance, and more detailed shots. The ultra-wide lens adds flexibility for landscape and architectural photography.

On the front, while details remain scarce, leaks suggest a 32 MP selfie camera, ideal for vlogging and video calls.

Design, Durability, and Battery

HMD’s design DNA has forever been one of functionality with a pinch of Scandinavian minimalism. The Fusion 2 is said to retain its sleek, robust build but now boasts IP65 dust and water resistance compared to the original’s IP54 rating. That renders it significantly more rugged and capable of everyday use — a feature that has been rare in modular devices.

Although the battery capacity has not been officially leaked, sources believe it will be sporting at least a 5000 mAh battery with fast charging capability (quite likely as high as 33 W). This should easily last a whole day even with heavy modular attachments on.

The phone is also rumored to have retained favorite features such as a 3.5 mm headphone jack, dual speakers, and NFC connectivity — little but significant inclusions that most contemporary flagships have ditched.

Software & Ecosystem Integration

One of HMD’s positives is its software. The company has a reputation to deliver clean, bloatware-free Android experiences and regular updates. Although Android 15 is imminent, the Fusion 2 will possibly go live with Android 14, with at least three years of OS upgrades.

The Smart Outfits Gen 2 modules should work seamlessly with HMD’s companion app, enabling users to tailor module functions, update firmware, and even download new features for compatible accessories. That means HMD is not only creating hardware — it’s creating a modular software ecosystem too.

Connectivity & Ports

For connectivity, the phone will come with Bluetooth 5.3, dual-band Wi-Fi, USB-C, dual-SIM 5G, and NFC. Support for the 3.5 mm headphone jack is a welcome addition for music lovers, making compatibility with old wired headphones possible.

What Makes HMD Fusion 2 Stand Out

In an industry flooded with glass-and-metal slabs that are indistinguishable from one another both in looks and feel, the HMD Fusion 2 excels by being revolutionary. The fact that it’s modular provides customization that most phones can only dream of.

Picture adding a projector to cast movies onto any wall, or clipping on a camera grip with a physical shutter release for DSLR-level control. For filmmakers, travelers, and tech fans, this might be revolutionary.

But the largest hurdle is ecosystem adoption. If HMD can keep the Fusion 2 at competitive prices and make Smart Outfits generally available, it could well rekindle enthusiasm for modular phones — a segment even Google and Motorola couldn’t make mainstream.

Expected Launch & Pricing

There is no official launch date as of yet, but rumors point towards an early 2026 release. The pricing is not clear, though analysts predict that it should begin at ₹28,000–₹32,000 in India (~$350–$400), depending upon the configurations.

Considering the hardware improvements and modularity features, that would be a very competitive product in the mid-range segment.

Final Thoughts

The HMD Fusion 2 is not merely another Android phone — it’s a futuristic experiment that sets out to combine innovation, functionality, and personalization. From the Snapdragon 6s Gen 4 processor and 120 Hz OLED screen to the Smart Outfits Gen 2 platform, every aspect of this phone shouts innovative design.

If the leaks hold true, HMD could finally have a modular smartphone that balances performance, durability, and versatility — something tech enthusiasts have long dreamed of. Now all eyes are on the official launch to see whether this concept translates into real-world success.
