Battery test: Oppo's Find X9 Pro crushes iPhone 17 Pro Max & Pixel 10 Pro XL

Oppo recently brought its latest Find X9 and X9 Pro flagship phones to the global market. Both devices boast powerful cameras and even more impressive battery capacities. The “Pro” variant especially stands out in this regard with its massive 7,500mAh cell. You might be wondering if the Oppo X9 Pro’s impressive battery capacity figure is reflected in real-world usage, and fortunately, an extreme battery endurance test against the iPhone 17 Pro Max and the Google Pixel 10 Pro XL is now available to clear your doubts.

The results, courtesy of the YouTube channel "Lover Of Tech," confirm that Oppo’s huge cell is far more than just a marketing claim.

The ultimate battery stress test

To measure true endurance, the test subjected all three flagship phones to continuous, demanding use, running popular applications for an hour each until the batteries completely drained. This included a mix of tasks that stress different components: running heavy games like Asphalt, streaming and recording 4K video, live social media features, and continuous playback of videos on TikTok and YouTube.

The competition buckled quickly under the strain. The Google Pixel 10 Pro XL was the first to wave the white flag, giving up after 7 hours of screen-on time. Minutes later, the iPhone 17 Pro Max followed, lasting just a hair longer at 7 hours and 17 minutes.

Oppo Find X9 Pro gets four hours on-screen time advantage in battery test

When the dust settled, the Oppo Find X9 Pro wasn't just slightly ahead; it set a clear dominance.

More specifically, the Oppo Find X9 Pro's battery allowed it to continue running games, apps, and services for a total of 11 hours and 17 minutes of on-screen time. This performance advantage of over four hours compared to the closest competitor highlights exceptional battery management combined with the benefit of its big 7,500mAh power cell.

For potential buyers, these numbers translate into real-world convenience. This is a phone that can easily handle a day of heavy use—even with constant recording and gaming—without needing a charger. Users with lighter usage patterns could easily push the device for two days or more, making the Oppo Find X9 Pro a serious contender for anyone whose priority is maximum battery life.
