Oppo Mini-Flagship Fails: Huge Potential Wasted by Poor Efficiency

Oppo Is Squandering Great Potential

Oppo is squandering great potential with its Find X9s Pro in terms of endurance due to a lack of efficiency at low system load. Although the 7,025 mAh battery looks like a real highlight on paper, the Find X9s Pro cannot match the fantastic runtimes of the Find X9 Pro in our review. The mini flagship powered by the Dimensity 9500, is simply too wasteful in idle mode with the the energy available.

Power Consumption Figures Expose the Problem

The power‑consumption figures in our idle measurements clearly expose the efficiency problem. While other top smartphones from Oppo, such as the Find X9 or even the significantly larger Find X9 Pro, remain below 2 watts in idle mode, the Find X9s Pro consumes noticeably more energy. Our Geekbench and GFXBench measurements, taken with the display brightness adjusted to 150 cd/m², clearly indicate the lack of optimization.

Idle Mode Results Are Alarming

In idle mode, the Find X9s Pro consumes around 3 watts, more than three times as much power as the large flagship model, the Find X9 Pro, which is also powered on MediaTek’s Dimensity 9500. However, the Find X9s Pro’s extra-large battery only partially conceals its inefficiency. In our web surfing battery test, the Oppo phone delivers a really good stamina for the compact smartphone class. Compared to the Samsung Galaxy S26, the Find X9s Pro lasts almost 10 hours longer.

However, due to the high power consumption at low system load, Oppo is giving away valuable screen‑on time that could have made the mini‑flagship a true endurance champion. Even the larger flagship model, the Find X9, with an identical battery capacity but larger OLED screen, lasted longer in our battery test.

Pricing and Specs
