Anyone looking for long battery life, extensive features and a modern design in a flagship smartphone might find the Find X9 Pro to be the perfect companion. However, our review of the Oppo device also reveals unexpected weaknesses in the Mediatek chipset.

The Oppo Find X9 Pro cuts a good figure in our review with its premium design and remarkable battery life. The smartphone's battery combines silicon and carbon in its anode, resulting in a very high capacity of 7,500 mAh. For comparison, an Apple iPhone 17 Pro Max weighs 7 grams more than the Oppo phone, but its battery only has a capacity of around 5,000 mAh.

Thanks to the large battery and an efficient chipset manufactured via the 3nm process, the Oppo Find X9 Pro delivered exceptionally strong battery life in our practical battery tests, providing over 34 hours in our Wi-Fi test at an adjusted display brightness of 150 cd/m².

However, MediaTek's flagship SoC falls somewhat short of expectations, as the chipset is somewhat weak, at least in the form of the Find X9 Pro.

Benchmark results of the Oppo Find X9 Pro are not always outstanding

Although the MediaTek Dimensity 9500 is a very powerful and reliable chipset for everyday use, the Find X9 Pro exhibited significant throttling in our tests. In the 3DMark stress tests, we observed a performance drop of up to 80%. While we didn't notice any limitations in our review, noticeable performance fluctuations cannot be ruled out, especially in demanding applications such as games or graphics-intensive tasks.

But even aside from the SoC throttling, the benchmark results weren't entirely convincing. While this was a strength of its predecessor, the Find X9 Pro exhibited some weaknesses in the AI ​​tests. The same applies to the measured values ​​of the UFS 4.1 storage, as the write speeds of the Find X9 Pro were particularly weak. This is likely due to the Dimensity 9500's built-in memory controller rather than the storage hardware itself.

The exact values ​​of the mentioned benchmarks (UL Procyon AI Inference, Geekbench AI, Androbench) and many other tests can be found here.
