Display
- Nautilus U618: Features a 6.5-inch AMOLED display with a 120Hz refresh rate, offering vibrant colors and smooth scrolling. Its higher resolution (FHD+) provides sharper visuals, making it excellent for media consumption and gaming. However, the display might consume more battery than a lower-spec panel.

- Winner: nautilus u618
Processor
- Nautilus U618: Equipped with a flagship-level Snapdragon 8 Gen 2 processor, delivering exceptional performance for demanding tasks, gaming, and multitasking. This chip ensures a fluid and responsive user experience. The downside is its higher power consumption and potential for heat generation under heavy load.
- U616: Utilizes a mid-range Snapdragon 695 processor, which is capable for everyday tasks like browsing, social media, and light gaming. It offers good power efficiency. However, it will struggle with graphically intensive games and heavy multitasking compared to the u618.
- Winner: nautilus u618
Camera System
- Nautilus U618: Boasts a versatile triple-camera setup with a 50MP main sensor, a 12MP ultrawide, and an 8MP telephoto lens with optical zoom. This configuration allows for high-quality photos in various conditions and provides flexibility for different shooting scenarios. The advanced image processing further enhances detail and color.
- U616: Features a dual-camera system with a 48MP main sensor and a 2MP macro lens. While the main sensor can capture good daylight photos, it lacks the versatility of the u618’s setup, particularly the absence of an ultrawide or telephoto lens.

Battery Life & Charging
- Nautilus U618: Packs a 4500mAh battery with support for 65W fast wired charging and 15W wireless charging. This combination offers good endurance for a full day of moderate use and very quick top-ups. The wireless charging adds convenience.

Build Quality & Design

- U616: Generally sports a plastic build, which makes it lighter and more resistant to drops than glass. The design is functional and practical, often with a matte finish that resists fingerprints. While durable, it lacks the premium aesthetic of the u618.

- U616: Usually comes with more modest storage options, often starting at 64GB or 128GB, with UFS 2.2 or eMMC storage. It often includes a microSD card slot for expandable storage, which is a significant advantage for users who need a lot of space on a budget.

Audio
- Nautilus U618: Usually features stereo speakers for an immersive audio experience and often includes support for high-resolution audio codecs. The sound quality is generally rich and detailed, enhancing media playback. The absence of a 3.5mm headphone jack might be a drawback for some.
- U616: Typically comes with a single bottom-firing speaker, which is adequate for notifications and casual listening but lacks the depth and richness of stereo speakers. It often retains the 3.5mm headphone jack, which is a plus for users who prefer wired headphones.
- Winner: nautilus u618
Connectivity
- Nautilus U618: Supports the latest Wi-Fi 6E and Bluetooth 5.3 standards, ensuring faster and more stable wireless connections. It also includes NFC for contactless payments and advanced 5G capabilities. These cutting-edge standards provide a superior connectivity experience.
