We're pitting a device representing the dawn of mobile smartphones – the O2 XDA Atom with its Windows Mobile operating system – against the modern, performance-focused Xiaomi Poco F5. This isn't a fair fight in terms of raw capability, but it's a fascinating look at how far smartphone technology has advanced in less than two decades.
🏆 Quick Verdict
For the vast majority of users, the Xiaomi Poco F5 is the clear winner. Its Snapdragon 7+ Gen 2 chipset, vibrant 963 nit display, and impressive 67W charging deliver a modern smartphone experience the XDA Atom simply cannot match. However, the XDA Atom holds value as a collector's item and a piece of mobile history.

- Long battery life (118h endurance)
- Modern Android OS
- May not appeal to retro tech enthusiasts
- Build quality may not match premium flagships
Display Comparison
The contrast between the displays is stark. The Poco F5 boasts a 963 nit peak brightness, ensuring excellent visibility even in direct sunlight, a feature completely absent in the XDA Atom’s older technology. While the XDA Atom’s display specifications are largely unknown, it’s safe to assume it lacks the color accuracy and viewing angles of a modern IPS panel. The Poco F5’s ‘Infinite’ (nominal) contrast ratio further enhances visual clarity, providing deeper blacks and more vibrant colors.
Camera Comparison
Both devices offer photo and video capabilities, but the specifics are worlds apart. The XDA Atom’s camera technology is limited by its age, likely offering low resolution and poor image quality. The Poco F5, while not a flagship camera phone, benefits from modern image processing algorithms and likely a larger sensor (though sensor size is unspecified). The Poco F5’s camera is capable of capturing detailed photos and videos in various lighting conditions, a capability the XDA Atom simply cannot replicate.
Performance
The performance gap is immense. The O2 XDA Atom’s 416 MHz Intel PXA272 processor is dwarfed by the Xiaomi Poco F5’s Qualcomm Snapdragon 7+ Gen 2. The Snapdragon 7+ Gen 2, built on a 4nm process, features an octa-core configuration with a high-clocked Cortex-X2 prime core at 2.91 GHz, offering significantly faster processing speeds and improved efficiency. This translates to a vastly smoother user experience, faster app loading times, and the ability to handle demanding tasks like gaming on the Poco F5, something the XDA Atom would struggle with even for basic functions.
Battery Life
Battery technology has also evolved dramatically. The Poco F5’s endurance rating of 118 hours and active use score of 11:52h demonstrate impressive battery life, further enhanced by its 67W wired charging, capable of reaching 100% in just 46 minutes. The XDA Atom’s battery life, while adequate for its time, would be significantly shorter by today’s standards, and its charging technology is undoubtedly much slower. The Poco F5’s support for PD3.0 and QC4 adds to its charging versatility.
Buying Guide
Buy the O2 XDA Atom if you're a collector of vintage technology, fascinated by the history of mobile computing, or seeking a unique conversation piece. Buy the Xiaomi Poco F5 if you prioritize performance, battery life, a modern operating system, and a vibrant display for everyday use and gaming.
