Real-world charging performance for UK flagship users

The OPPO Find X9 Pro introduces a 7,500 mAh silicon-carbon battery designed for multi-day endurance, making it one of the biggest battery capacities in a mainstream flagship phone. UK users are consistently experiencing well over a full day of heavy usage and close to two or three days with moderate use.

In wired testing, the Find X9 Pro supports 80 W fast charging and reaches around 50% in roughly 30 minutes, with a full charge taking just over an hour. This makes the device extremely practical for daily top-ups, especially for users who rely heavily on navigation, gaming or 5G connectivity during long workdays.

Wireless charging performance is also strong, thanks to 50 W wireless charging support. This ensures users who prefer placing the phone on a charging pad don’t sacrifice charging speed. Reverse wireless charging is available at 10 W for powering smartwatches, earbuds and similar accessories when on the go.

Battery health is another standout factor, with OPPO promising the battery will retain at least 80% capacity after five years of use. This makes the Find X9 Pro a reliable long-term option for UK buyers who tend to keep their phone through multiple software update cycles rather than upgrading yearly.

In everyday usage, a morning charge can comfortably take users through a full working day and deep into the evening. A short wired boost during lunch or a quick wireless session while relaxing can easily push the device through a second day, reducing the need for overnight charging.

Even though 80 W wired and 50 W wireless charging are not the fastest on the market, the strength of the Find X9 Pro lies in the combination of huge battery size and consistently rapid charging speeds. Heavy gaming, prolonged camera recording and maximum screen brightness can reduce endurance, but the large power reserve offsets this well.

For frequent business travellers, students and creators who rely heavily on their phones, the Find X9 Pro offers genuine freedom from constant charger anxiety. The wireless and reverse wireless options also ensure maximum flexibility when managing multiple devices.

In summary, the OPPO Find X9 Pro delivers one of the most balanced battery and charging systems in 2025. With multi-day longevity, fast wired and wireless speeds and strong long-term battery durability, it stands out as an excellent choice for UK users who prioritise stamina and convenience in a flagship smartphone.
