iQOO Z11S will feature a 2K 144Hz display with up to 2,000 nits full-screen brightness.The phone will pack a 10,000mAh battery, the largest battery seen on an iQOO phone so far.iQOO Neo 11 Ultra has appeared on Geekbench with the Dimensity 9500, 16GB RAM and Android 16.The Neo 11 Ultra reportedly scored 2,923 in single-core and 9,700 in multi-core testing.Both smartphones are scheduled to launch in China on August 18.Pricing and global availability are yet to be announced.What iQOO has Actually ConfirmedThe Z11S display: 2K resolution, 144Hz refresh rate, 2,000-nit brightness across the full panel rather than in one small patch, which is the more meaningful number since most phones only hit peak brightness in a limited zone. iQOO also lists 2160Hz PWM dimming, DC dimming at full brightness, and SGS certification for low blue light and reduced flicker.The battery is the bigger claim. A 10,000mAh single-cell unit built with CATL, iQOO's largest to date. The company's own endurance figures: roughly 17 hours of navigation, 29 hours of short-video playback, 14.6 hours of gaming, and 57 per cent remaining after a simulated 16-hour daily-use test. Charging is expected at 44W. iQOO has not confirmed that figure.Key Specifications of iQOO Z11SZ11S detailStatus2K display, 144HzConfirmed, official teaser2,000-nit full-screen brightnessConfirmed, official teaser10,000mAh battery, CATL cellConfirmed, official teaserEndurance claims (17 hr nav / 29 hr video / 14.6 hr gaming)Confirmed, company figures, not independently tested44W chargingUnconfirmedPriceUnconfirmedIndia launchUnconfirmedWhat a Geekbench Listing Does and Doesn't ProveA Geekbench 7 listing for the Neo 11 Ultra confirms the presence of the Dimensity 9500 chip, 16GB of RAM, and Android 16. It scored 2,923 in single-core and 9,700 in multi-core tests, figures that are generally trustworthy, as Geekbench results are difficult to fabricate and typically reflect real hardware. However, the listing also shows a Mali-G1 Ultra MC11 GPU, whereas the standard Dimensity 9500 uses an MC12 configuration with one additional GPU core. This reduction could affect graphics performance, though real-world impact during everyday use remains uncertain.Other rumoured features, such as a 6.83-inch flat 2K OLED display, a battery in the 9,000 mAh range, 100W fast charging, an ultrasonic fingerprint sensor, and a 50MP dual-camera system with optical image stabilisation, are based on earlier leaks unrelated to the benchmark. None of these have been verified by iQOO.
