iQOO Z11 Goes Official: 9020mAh Battery, 165Hz Display, 90W Charging

The iQOO Z11 has been launched in China, targeting users who want long battery life, high refresh rate visuals, and stable gaming performance. The device introduces a larger battery, an updated chipset, and new display features.

Battery capacity is the headline feature. The phone packs a 9,020mAh “Blue Ocean” battery, the largest used in an iQOO device so far. It uses a fourth-generation silicon anode and semi-solid-state battery cells to maintain a relatively slim 8.25mm profile while improving performance in low temperatures. The company claims over 10 hours of mixed usage with more than 50 percent charge remaining. The device supports 90W wired charging and also allows reverse charging for other devices.

The Z11 runs on the MediaTek Dimensity 8500 chipset, built on a second-generation 4nm process. It uses Cortex-A725 cores in an all-large-core architecture aimed at improving efficiency. iQOO adds its Monster Over-Core Engine, which includes a Prophet Scheduler for background task control and a Lightning Accelerator to stabilize frame rates. The phone also includes a 7K Ice Dome VC liquid cooling system. The brand claims a benchmark score exceeding 2.62 million.

On the front, the device features a 6.83-inch AMOLED display with a 1.5K resolution of 2800×1260 pixels and a 165Hz refresh rate. It supports up to 5000 nits peak brightness, 2160Hz PWM dimming, and DC-like dimming. The panel is designed to reduce latency and improve touch response during gaming.
