Display Comparison
When it comes to display technology, the Redmi K80 Ultra clearly takes the lead. It sports a large 6.78-inch AMOLED display with a sharp resolution of 1440 x 3200 pixels and a pixel density of 518 PPI. The screen supports features like 2400Hz PWM dimming, HDR10+, HDR Vivid, and an impressive 4000 nits peak brightness for excellent outdoor visibility. The 144Hz refresh rate ensures ultra-smooth scrolling and gaming experiences.
On the other hand, the Poco C3 features a 6.53-inch IPS LCD screen with a 270 PPI pixel density and a lower screen-to-body ratio of approximately 80.3%. While adequate for everyday use, it lacks the vivid color reproduction and smoothness of the K80 Ultra.

Technical Features and Build Quality
The Redmi K80 Ultra runs on Android 15 with HyperOS and is powered by the cutting-edge MediaTek Dimensity 9400+ chipset. This octa-core processor delivers flagship-level performance for gaming, multitasking, and demanding applications.
Its build quality includes a metal frame, fully equipped peripherals, enhanced sound quality, and full-level waterproofing—an impressive set of features missing in many competitors. Despite not including a telephoto lens, the focus remains on performance and durability.
The Poco C3, by contrast, runs on Android 10 and is powered by the MediaTek Helio G35, which is suitable for entry-level usage but not ideal for high-performance tasks.

Battery and Charging
Battery life is one of the biggest differentiators. The Redmi K80 Ultra is rumored to feature a 5580mAh battery with support for 120W fast charging, ensuring that users spend minimal time near a charging cable.
In comparison, the Poco C3 has a 5000mAh battery with standard 10W charging, which is sufficient but lacks the rapid charging capabilities of the K80 Ultra.

Network and Connectivity
Both phones support dual SIM and come with modern connectivity options. However, the Redmi K80 Ultra is clearly more future-ready with features like 5G support, Bluetooth v5.4, NFC, and a USB Type-C 3.1 port.
The Poco C3 only supports 4G, lacks NFC, and has micro-USB connectivity, making it less ideal for those looking for modern network options.

Conclusion
The Redmi K80 Ultra is undoubtedly a power-packed flagship device crafted for users who prioritize high-end performance, stunning visuals, fast charging, and durability. With its advanced Dimensity 9400+ chipset, AMOLED display, 50MP camera system, and 120W fast charging, it’s a device aimed squarely at premium users in 2025.
On the other hand, the Poco C3, while dated and less powerful, continues to be a practical and affordable smartphone for users who only need essential features. It served its purpose well during its time but now lags significantly behind modern standards.
In short, if you’re willing to invest in top-notch features and cutting-edge technology, the Redmi K80 Ultra is your ideal choice. But for budget-conscious users who want basic functionality, the Poco C3 remains a solid option.
