OnePlus 16 Review: Most Powerful OnePlus Phone With Exceptional Battery Life

OnePlus 16 Review: Flagship Performance Meets Marathon Battery Life

The OnePlus 16 arrives as the most powerful device in the company’s history, pushing boundaries in both processing capability and energy efficiency. After extensive testing, this flagship stands toe-to-toe with competitors like the Samsung Galaxy S25 Ultra and Apple iPhone 16 Pro Max in raw performance metrics while surpassing many in battery longevity.

Uncompromising Performance Powered by Snapdragon 8 Elite

At the heart of the OnePlus 16 sits Qualcomm’s Snapdragon 8 Elite chipset, the same silicon driving the Xiaomi 15 Ultra and ASUS ROG Phone 9. In synthetic benchmarks, the device posts Geekbench 6 scores exceeding 3,200 in single-core and 9,800 in multi-core tests, placing it among the absolute top tier of Android smartphones. Real-world usage reflects these numbers: app launches are instantaneous, multitasking between heavy applications like Adobe Lightroom Mobile and Genshin Impact remains fluid, and the 120Hz LTPO display maintains buttery smoothness even under sustained load.

Battery Life That Redefines Expectations

The 6,100 mAh silicon-carbon battery represents a significant upgrade over the OnePlus 12‘s 5,400 mAh cell. In our standardized video playback test at 150 nits brightness, the OnePlus 16 endured for 22 hours and 40 minutes — outperforming the Samsung Galaxy S25 Plus by nearly three hours and the Google Pixel 9 Pro XL by over four hours. Even with intensive gaming sessions at maximum brightness, the phone comfortably clears a full day of heavy use. The 100W SuperVOOC wired charging replenishes the battery in 26 minutes, while 50W wireless charging adds convenience for Qi2-compatible pads.

Camera System: Iterative but Capable

The triple camera array retains the OnePlus 12‘s 50MP Sony LYT-808 main sensor with OIS, a 64MP OmniVision OV64B periscope telephoto offering 3x optical zoom, and a 48MP ultra-wide. While hardware remains largely unchanged, Hasselblad color science refinements produce more natural skin tones and improved dynamic range in high-contrast scenes. Night mode performance rivals the vivo X100 Pro in many scenarios, though the Xiaomi 15 Ultra still holds an edge in extreme low-light detail retention. Video recording tops out at 8K/30fps or 4K/60fps across all lenses with Dolby Vision HDR support.

Import-Only Availability Remains the Biggest Hurdle

Despite its technical excellence, the OnePlus 16 launches exclusively in China and India initially, with no confirmed Western release timeline. Enthusiasts in Europe and North America must rely on importers like TradingShenzhen or Giztop, adding $100-$150 in markup and voiding official warranty coverage. This limitation makes the device difficult to recommend over the readily available Samsung Galaxy S25 series or OnePlus 13, which offer comparable experiences with local support and carrier compatibility.

Verdict: A Technical Triumph Hampered by Distribution

The OnePlus 16 proves OnePlus can still engineer world-class hardware. Its combination of Snapdragon 8 Elite performance, class-leading battery life, and refined OxygenOS 15 software creates a compelling flagship package. However, the import-only barrier significantly diminishes its practical appeal for Western buyers. If OnePlus expands availability globally, this device could challenge the Samsung Galaxy S25 Ultra and Apple iPhone 16 Pro Max for the title of best all-around smartphone in 2025. For now, it remains a tantalizing glimpse of what’s possible when a manufacturer prioritizes both power and efficiency without compromise.
