A new leak suggests the OnePlus 16 could feature a massive 9,000mAh battery, matching the capacity found in the brand's recently launched Turbo 6 series. This would represent a significant jump from the OnePlus 15's 7,300mAh cell, signaling a clear shift in the company's focus toward extreme battery life.

The move aligns with a broader industry trend where Chinese manufacturers are pushing battery capacities to new extremes. If the rumor holds, the OnePlus 16 would join a growing list of phones prioritizing endurance over slim profiles, a direct response to consumer demand for devices that can easily last multiple days.

The OnePlus 16 is expected to launch in China around October. Beyond the battery, it's rumored to feature a 200MP camera sensor and a display with an unprecedented refresh rate. The final product will need to balance this massive power cell with performance and charging speed, especially since the Turbo 6 series supports only 80W charging.
