My Choice

If I were to choose between these two, I'd lean towards the Sony Xperia 5 III. Despite its slightly smaller battery and less rapid charging, the superior display, the more powerful chipset, and the significantly more versatile camera system are hard to overlook. As a tech journalist and analyst, the ability to capture high-quality photos and videos as well as experience demanding games and applications with ease are aspects that align with my priorities. Additionally, the pocketable size and the more robust software support make it a compelling choice. However, if battery life was paramount and the budget was very tight, I would choose the Xiaomi Poco X3 GT.
