The highly anticipated OnePlus 15 has finally made its global debut this month, following its initial October launch in China. While it brings a host of premium features, one specification has dominated the conversation: its massive 7,300mAh battery. For smartphone users tired of midday charging, this promises a revolution in battery life. But the burning question remains: how does this translate into real-world, all-day usage? A rigorous new battery test has put the device through its paces, and the results are both impressive and revealing.
Putting the Giants to the Test
The definitive answer comes from the popular YouTube channel "Lover Of Tech," which has built a reputation for its thorough and consistent device testing. Following their recent review of the battery champion, the Oppo Find X9 Pro, they employed the same rigorous methodology to test the OnePlus 15. This time, they placed the new OnePlus flagship head-to-head against not only the reigning Oppo Find X9 Pro but also Apple's endurance stalwart, the iPhone 17 Pro Max.
It's worth noting that the global version of the OnePlus 15 retains the same colossal 7,300mAh cell found in its Chinese counterpart, unlike some other brands that alter specs for different regions. This means the results are directly applicable to the model you can buy today, ensuring what you see is what you get.
The Gauntlet: A Demanding Real-World Simulation
So, what does a modern battery test entail? This wasn't a simple screen-on test. "Lover Of Tech" designed a brutal, continuous loop of demanding tasks meant to simulate a very heavy day of use. Each task ran for one hour, draining the phones until the very last one powered down. The grueling schedule included:
- 4K Video Recording at 60fps: Maximizing processor and sensor usage.
- Intensive Social Media Scrolling: Including X Spaces, TikTok, and Instagram Reels.
- Continuous Video & Music Streaming: Hours of non-stop YouTube playback.
- Demanding Mobile Gaming: Sessions on popular titles like Subway Surfers and Asphalt.
- Video Calling & Live Streaming: A final push with WhatsApp video calls and TikTok Live.

The Results: A Clear Victory for Endurance
After hours of relentless testing, the final standings were clear. The OnePlus 15 put up a formidable fight, lasting an impressive 9 hours, 39 minutes, and 28 seconds before finally shutting down. For the average user, this translates to unparalleled freedom—easily a full day and well into the next of typical use without ever glancing at a charger. Battery anxiety, it seems, is genuinely a thing of the past for OnePlus 15 owners.
However, the crown for battery supremacy remains elsewhere. The Oppo Find X9 Pro, with its slightly larger 7,500mAh battery, managed to secure a staggering 11 hours of screen-on time, reaffirming its position as the undisputed battery king. The consistency of this result with the channel's previous tests adds significant weight to its claim.
For comparison, the iPhone 17 Pro Max, often lauded for its reliable battery life, reached a respectable 7 hours, 37 minutes, and 42 seconds. While solid, it highlights the significant gap that Android manufacturers have opened in the pure endurance race.
Conclusion: A Marathon Winner, But Not the Record Holder
The takeaway is clear: the OnePlus 15 delivers on its promise of exceptional battery life. With nearly ten hours of intense use, it stands as one of the longest-lasting phones on the market and is a top-tier choice for any power user.
The notable gap between the OnePlus 15 and the Oppo Find X9 Pro, despite a relatively small 200mAh battery difference, suggests that software optimization and power management still play a crucial role. Oppo's proprietary chipset and software tweaks seem to eke out every last drop of performance from its cell.
Ultimately, if your primary concern is never, ever worrying about your phone's battery from morning until night, the OnePlus 15 is an phenomenal option. But for those who demand the absolute maximum endurance that modern smartphone technology can provide, the throne still belongs to the Oppo Find X9 Pro.
