The iQOO Z11S is being positioned as a practical device focused on visual experience and long battery life. The full reveal is set for August 18 in China.

Latest teasers confirm the phone will come with a 2K 144Hz panel with support for 2160Hz high-frequency PWM dimming and full-brightness DC dimming. These eye-protection features are aimed at reducing fatigue during long reading, video or gaming sessions. The phone has reportedly earned SGS eye-comfort certification for low blue light and low flicker.
For gamers, the company has also added its own touch optimisations to cut motion blur and improve responsiveness. The display hits 2000 nits of peak brightness across the whole panel, which should help outdoors.

The other big talking point is the battery. The Z11S will pack a 10,000mAh battery, the largest iQOO has ever put in a phone. It’s a single-cell design developed together with CATL. Previously reported endurance numbers look strong: around 17 hours of continuous navigation, 32 hours of WeChat voice calls, 29 hours of short-video playback, and about 14.6 hours of mainstream mobile gaming.
In a simulated full-day intensive student-style use case (daytime messaging, standby and music, then evening gaming, video and calls for a total of 16 hours), the battery reportedly had 57% left. That should comfortably support multi-day use under normal loads. Charging is expected to support 44W with common protocols, though the full official confirmation is still pending the launch event.
A Geekbench listing for a related model (V2603A) suggest a MediaTek Dimensity 7500-series chipset running Android 16 with at least 12GB of RAM, which points to solid mid-range performance that should pair well with the large battery. Colour options and a dual rear-camera setup (including a 50MP main sensor in some reports) have also shown up in promotional material. The Z11S is expected to launch alongside the higher-positioned Neo 11 Ultra series in China.
