OnePlus 15 vs Xiaomi Poco F8 Pro — charging, power and real-world speed
Flagship Power Meets High-Value Performance
The comparison between the OnePlus 15 and the Xiaomi Poco F8 Pro highlights two very different approaches to power delivery, charging performance and real-world speed. OnePlus aims for top-tier refinement with its flagship design, while Poco focuses on delivering strong performance at a far more accessible price point. For UK users, these differences directly affect everyday usage and overall value.
The OnePlus 15 enters the market with Qualcomm’s Snapdragon 8 Elite Gen 5 chipset, offering excellent processing power and stability. Its 6.78-inch LTPO display supports high refresh rates for smooth interactions in gaming, browsing and multitasking. This combination gives the device a premium feel and consistent responsiveness throughout extended use.
The Poco F8 Pro, although positioned at a lower price tier, uses high-performance hardware that brings strong day-to-day speed. Its Snapdragon chipset, while not the newest in the series, still delivers fast opening times and competent multitasking. With a display refreshed at up to 120Hz, it offers fluid animations and responsiveness suitable for gaming and media.

Battery capacity plays a major role in real-world performance. The OnePlus 15 features a large battery designed to comfortably endure a full day of mixed usage, including streaming, photography and navigation. Its efficiency, combined with its advanced chipset, helps support long sessions without significant drops in performance. This level of endurance is ideal for UK users who prefer fewer charging intervals.
Charging technology is another area where OnePlus stands out. The OnePlus 15 supports high-wattage wired charging that brings the battery from empty to full in a short span, making it convenient for users with busy schedules. Wireless charging support further enhances flexibility. These features make the phone well-equipped for fast-paced lifestyles.
The Poco F8 Pro also offers fast charging, though at slightly lower wattage. Despite this, it remains capable of reaching high charge levels quickly, which suits users who value efficiency without needing the highest possible charging speeds. This makes the device practical for daily use while keeping costs down.
In terms of real-world speed, the OnePlus 15’s higher refresh rate display and more advanced processor give it a noticeably smooth and polished feel. App switching, gaming and heavy tasks run without interruption, and the software optimisation helps maintain this performance over time. This makes it a strong choice for users who prioritise consistently high responsiveness.
The Poco F8 Pro performs well in practical usage too, especially at its price. While it may not reach the flagship polish of the OnePlus 15, it handles social media, video streaming, games and daily apps without difficulty. For most users, it provides all the speed needed for a reliable and enjoyable experience.
Both phones appeal to different types of UK buyers. The OnePlus 15 is ideal for those seeking maximum performance, higher charging convenience and a premium day-to-day feel. The Poco F8 Pro is suited to users who want excellent power and charging speeds at a more affordable price, without needing top-tier flagship refinement.
In conclusion, the OnePlus 15 wins in charging speed, peak power and overall real-world smoothness, making it the stronger flagship choice. The Poco F8 Pro delivers impressive performance for its price, offering solid power and fast charging that represent excellent value for budget-conscious users.
