The Android landscape has just witnessed a heavyweight clash. In a detailed comparison by GKOnline, the newly debuted Motorola Signature is going head-to-head with the reigning champion of productivity, the Samsung Galaxy S25 Ultra.
While Samsung has long held the crown for the “do-it-all” flagship, Motorola’s latest entry aims to disrupt the market with a blend of ultra-premium design and industry-leading charging speeds. Here is how these two titans stack up.
Design and Display: Elegance vs. Utility
Motorola is leaning heavily into lifestyle aesthetics with the Signature. The device features a unique, fabric-inspired back panel (offered in Pantone-validated finishes) and an incredibly slim 6.99mm profile. Despite its size, it remains remarkably light at 186g.
Samsung’s S25 Ultra sticks to its bold, titanium-clad identity. While slightly heavier at 218g, it offers the distinct advantage of the integrated S Pen, a tool that remains unrivaled for note-taking and precision tasks.
On the display front, the competition is fierce:
- Motorola Signature: Features a 6.8-inch LTPO AMOLED panel with a blistering 165Hz refresh rate and a record-breaking 6,200 nits peak brightness.
- Galaxy S25 Ultra: Boasts a 6.9-inch Dynamic AMOLED 2X display. While its 120Hz refresh rate and 2,600 nits are lower on paper, it includes a superior anti-glare coating that makes it much more legible in direct sunlight.
Performance and AI
Under the hood, the two phones take different approaches to power:
- The Galaxy S25 Ultra utilizes the Snapdragon 8 Elite for Galaxy, a custom-tuned chip that prioritizes on-device AI and efficiency. Samsung’s “Galaxy AI” suite remains the most mature in the industry, offering features like Circle to Search and advanced live translation.
- The Motorola Signature runs on the Snapdragon 8 Gen 5. While the naming suggests a newer architecture, real-world benchmarks show both are exceptionally fast. Motorola counters Samsung’s software with Moto AI 2.0 and a unique 24×7 “Signature Club” concierge service for users.
Camera Systems: 200MP vs. Sony Lytia
Samsung continues to lead in raw resolution with its 200MP main sensor, which provides incredible detail and versatile zoom capabilities via its quad-lens array (including a 5x periscope telephoto).
Motorola, however, is focusing on sensor quality over megapixel counts. The Signature uses a triple 50MP Sony LYTIA setup. This includes a 50MP periscope lens and a 50MP ultrawide, ensuring high-quality images across all focal lengths without the “drop-off” in quality sometimes seen on secondary lenses.
Battery and Charging: No Contest
This is where Motorola takes a commanding lead. The Signature packs a 5,200mAh silicon-carbon battery and supports 90W wired charging and 50W wireless charging.
In contrast, the Galaxy S25 Ultra houses a 5,000mAh battery and remains capped at 45W wired charging. While Samsung’s battery life is excellent and reliable for a full day, it simply cannot match the “top-up” speeds of the Motorola.
