C24 Ultra 5G Smartphone 16+512GB Unlocked - Long Battery, Pen

In this review of the C24 Ultra 5G Smartphone the bottom line is simple: this is a large-display, camera-focused Android phone for power users who want long runtime and a built-in pen. The phone stands out for its 6.8' HD screen with a high refresh rate and a massive 6800mAh battery that keeps you going through a full day of heavy use. Our review found the combination of a 108MP main camera, Snapdragon-class performance and the built-in pen make it a good fit for content creators who also prioritize battery life.

Key Features

• 6.8' HD display: A large 6.8' screen with 3088 x 1440 resolution and 120Hz refresh rate delivers smooth motion and vivid colors for video and web browsing.
• 6800mAh battery: A big battery and 20W fast charging provide extended screen time and quicker top-ups when you need power in a hurry.
• Dual 108MP+48MP camera system: A 108MP main sensor plus a 48MP secondary camera and enhanced image processing produce detailed stills and sharper zoomed shots.
• High-performance CPU: A 10-core Snapdragon 8 Gen2 class processor improves app responsiveness, multitasking and gaming frame rates.
• Built-in pen: The integrated pen supports note taking and quick sketches without carrying a separate accessory.
• Android 13 OS: Modern Android 13 provides a familiar interface and up-to-date software features for daily use.

Who It's For

The C24 Ultra suits users who want a large-screen phone for media, photography and productivity: photographers who value a high-resolution main camera, commuters who need long battery life, and creators who appreciate an included pen for quick annotations. It is attractive for anyone who wants a high-storage 16+512GB configuration unlocked and ready for dual SIM 5G use.

People who prefer compact phones, need the absolute fastest charging tech, or require a highly water-resistant or ruggedized handset should look elsewhere. Also, those wanting official carrier-specific features or warranty tied to a network may prefer a carrier-branded model.
