iQOO appears to be preparing another addition to its Z-series lineup, with the iQOO Z11S now appearing in a new specifications leak. The information points to a large battery, high-refresh-rate display and a MediaTek Dimensity chipset, while a Geekbench appearance and 3C certification have reportedly revealed further details.

The specifications have not been officially confirmed by iQOO at this stage. However, the 10000mAh battery and 144Hz display have also appeared in recent coverage surrounding the upcoming iQOO Z11S, while the remaining specifications should be treated as leaked or reported information.

The iQOO Z11S is expected to feature a 6.83-inch display with a 144Hz refresh rate. The latest leak also claims support for DC-like dimming and 2160Hz PWM dimming, along with SGS certifications for low blue light and low flicker. A 144Hz refresh rate would allow the display to refresh more frequently than standard 60Hz panels, while the reported dimming technologies are focused on the display’s brightness control. However, the leak does not specify the panel type, resolution or peak brightness. Those details therefore cannot be confirmed from the available information.

10000mAh Battery Takes Focus

The biggest specification revealed for the Z11S is its reported 10000mAh battery. Recent reports around the upcoming phone have also highlighted the same battery capacity, making it one of the key details currently associated with the device. The Z11S is expected to launch alongside the iQOO Neo 11 Ultra in China on August 18, according to current reports. The charging information is less certain. The latest leak points to a 44W charger listed by China’s 3C certification database. While the listing supports the presence of a 44W charging solution, iQOO has not yet officially announced the phone’s charging specifications.

Dimensity 7500 and 12GB RAM

The leaked specifications also point towards a MediaTek Dimensity 7500 chipset. A separate Geekbench-related report has previously connected an upcoming iQOO Z-series smartphone with the Dimensity 7500 and 12GB RAM, adding some support to the latest information. The same report associated the device with Android 16. The latest leak similarly lists 12GB RAM and Android 16 for the Z11S. It is not yet clear whether 12GB will be the highest RAM configuration or whether iQOO will offer additional memory options.

The iQOO Z11S is also expected to arrive in White, Black and Green color options. An image accompanying the leak shows the phone in these three finishes, with a dual-camera arrangement on the rear. However, detailed camera specifications have not been provided in the available information, so no camera-related claims can be made at this stage. The color options are also based on the current leaked information and should not be treated as an official final list until iQOO confirms them.

What Has Been Confirmed So Far?

The distinction between confirmed and leaked information is important with the Z11S. Recent reports confirm that the iQOO Z11S is part of iQOO’s upcoming China launch alongside the Neo 11 Ultra, with the launch scheduled for August 18. The 10000mAh battery and 144Hz display have also been repeatedly reported ahead of the event. However, details such as the Dimensity 7500 chipset, 12GB RAM, Android 16, 44W charging, color options and display-dimming specifications are based on the latest leak and related listings. These details therefore remain subject to official confirmation.

Launch Could Reveal More

With the August 18 China launch approaching, iQOO is expected to provide the remaining details about the Z11S. Pricing, storage configurations, camera specifications, and the complete display specifications have not been established from the information currently available. For now, the reported combination of a 10000mAh battery and 144Hz display gives the Z11S its clearest identity, while the Dimensity 7500 and 12GB RAM suggest the phone could sit in the performance-focused segment of iQOO’s Z-series lineup.

Conclusion

The iQOO Z11S is tipped to feature a 6.83-inch 144Hz display, 10000mAh battery, and Dimensity 7500 chipset, alongside up to a reported 12GB RAM configuration and Android 16. While several specifications have surfaced through leaks and certification listings, iQOO is yet to officially confirm the complete specification sheet ahead of its August 18 China launch.
