Oppo Find X8 Ultra Shows Impressive Battery Endurance Under Heavy Usage
The Oppo Find X8 Ultra has become one of the most discussed flagships of 2025, not just for its design and camera but also for how it performs under intense workloads. With a large 5500mAh battery and the latest Snapdragon 8 Gen 4 chipset, users in the U.S. have been testing its endurance under demanding conditions such as gaming, multitasking, and 4K video recording. The results show that Oppo has achieved an excellent balance between raw power and battery efficiency.
Under continuous heavy load, the Find X8 Ultra managed to hold its own remarkably well. In battery drain tests that simulated real-world usage, including gaming, camera use, streaming, and multitasking, the phone lasted approximately 9 hours before dropping below 10% battery. This result is particularly impressive given its large QHD+ 120Hz AMOLED display. Even when running multiple background apps and brightness set to maximum, the phone maintained stability without rapid battery dips, suggesting that Oppo’s thermal and power management systems are finely tuned.
Gaming remains one of the most power-intensive scenarios, and here, the Find X8 Ultra demonstrated efficient power handling. Popular titles like Genshin Impact and Call of Duty: Mobile ran at consistent frame rates, with battery consumption averaging around 11–12% per hour in performance mode. With balanced mode enabled, consumption dropped to roughly 8% per hour while still maintaining smooth gameplay. The combination of the Adreno GPU and advanced cooling system clearly helps minimize energy loss, ensuring users can game for longer without frequent recharging.
Camera usage, especially with the new large 1-inch Sony sensor, can also put significant stress on the battery. Extended photography sessions, particularly in Pro and Night modes, consumed about 4–5% per 10 minutes. Recording 4K videos or using the periscope lens continuously increased power draw, but the heat remained under control. Even after 30 minutes of 4K recording, the phone’s temperature stayed below 40°C, and battery degradation was gradual, not abrupt. This shows that Oppo has successfully optimized the phone for sustained camera performance without compromising endurance.
When tested with productivity and media tasks such as document editing, video calls, and 4K streaming, the Find X8 Ultra delivered consistent results. Watching HDR content on Wi-Fi at full brightness for two hours drained around 18% of the battery. Meanwhile, multitasking between social media, browsing, and background app syncing resulted in a total drain of about 25% over four hours. Users in the U.S. have noted that the battery percentage tends to drop more evenly over time, avoiding the sudden dips often seen in other high-performance devices.
Thermal management is one of the biggest factors in battery performance under load, and the Find X8 Ultra impressed in this area as well. The new vapor chamber cooling system efficiently dissipates heat during intense sessions. In stress tests that ran benchmarks repeatedly for over an hour, the device maintained an average surface temperature of around 39°C. Performance throttling was minimal, which helped preserve both efficiency and battery longevity. Unlike many flagship phones that heat up quickly under sustained load, the Find X8 Ultra stayed relatively cool to the touch.
Charging recovery after heavy drain is another highlight. The phone supports 100W SuperVOOC charging, which refills the battery from 0% to 50% in just about 10 minutes and reaches full capacity in under 25 minutes. This quick recharge ability compensates for any battery loss during extended gaming or filming sessions, ensuring minimal downtime. Even after multiple charge cycles, the battery health remains stable, reflecting Oppo’s improvements in fast-charging safety and long-term efficiency.
Overall, the Oppo Find X8 Ultra’s battery drain results under load show a well-optimized balance between power and endurance. Whether it’s high-end gaming, extensive camera use, or demanding productivity tasks, the phone manages to deliver consistent performance without excessive heat or rapid depletion. For U.S. users seeking a flagship that can handle heavy workloads while maintaining long-lasting battery life and quick recharging, the Find X8 Ultra proves to be a strong contender among 2025’s top premium smartphones.
