A flagship phone (not an iPhone or Galaxy) boasts impressive battery life, needing only four charges in a week.
I now realize that exceptional battery life might have ruined other phones for me.
It essentially lasts for two days between charges, an impressive feat compared to my experience with other phones in recent years.
The reason is clear when examining the specs. The Oppo Find X9 Pro incorporates a substantial 7,500 mAh silicon-carbon battery, offering a significant capacity advantage over most phones officially available in the US. This includes the 5,000mAh Galaxy S25 Ultra, now surpassed by the iPhone 17 Pro Max and Pixel 10 Pro XL, which feature larger batteries.
Beyond the large battery, the Oppo Find X9 Pro uses MediaTek's Dimensity 9500 chip. This 3nm octa-core chip offers performance improvements, rivaling the Qualcomm Snapdragon 8 Elite and Apple A19 Pro, with notable efficiency. MediaTek states the chipset has 37% reduced peak CPU usage and a 55% improvement in the highest-clocked Ultra core's power efficiency compared to the Dimensity 9400.
While these claims sound good, the actual impact is hard to gauge.
The Oppo Find X9 Pro's performance in independent battery tests better demonstrates its efficiency and battery life. It excels in these tests, ranking third overall for battery life, only surpassed by the Asus Zenfone 10 and Sony Xperia 10 IV. The Find X9 Pro distinguishes itself as a flagship without compromising on key features.
The Find X9 Pro stands out among flagship phones from the last few years, outperforming Samsung, Apple, and Pixel devices.

The Find X9 Pro lasted 25 hours and 34 minutes in our video streaming test. Only the Zenfone 10 did better. The Find X9 Pro achieved 13 hours and 30 minutes in our browsing test, a respectable result. In the 3D gaming test, the Find X9 Pro reached 11 hours and 17 minutes, a good result that marks this Oppo phone as a strong performer.
However, long battery life can be achieved by combining an efficient chip and a large battery.
The challenge lies in maintaining an elegant design while incorporating all the hardware. The Find X9 Pro is just 8.3 mm thick, less than the iPhone 17 Pro Max's 8.75mm.
Moreover, the weight is reasonable. At 224 grams, it is not the lightest flagship, but not among the heaviest either.
Overall, this Oppo is my preferred flagship, and I intend to continue using it until something better appears.
