iQOO Z11S launched China with 10,000mAh battery and 144Hz AMOLED display

iQOO has launched the Z11S in China with a 10,000mAh battery, a Dimensity 7500 chipset, and an 8.59mm body. The starting 8GB + 128GB model is priced at CNY 1,999, making it a notable entry in the battery-first mid-range phone segment.

iQOO Z11S adds 144Hz AMOLED display, 5000-nit peak brightness

The iQOO Z11S pairs that large battery with a 6.83-inch flat OLED display at 1.5K resolution. It also supports a 144Hz refresh rate, which should help with smoother scrolling and gaming.

iQOO says the panel can reach 5,000 nits peak brightness and uses 2,160Hz PWM dimming. Those are the main display numbers that stand out here, and they suggest the phone is being positioned for users who spend a lot of time on media and games.

• Display size: 6.83 inches
• Panel type: flat OLED
• Resolution: 1.5K
• Refresh rate: 144Hz
• Peak brightness: 5,000 nits
• PWM dimming: 2,160Hz

With that setup, the Z11S is not just leaning on battery size alone. The screen specs make it look like a more balanced mid-range device, even if endurance remains the clearest selling point.

50MP autofocus camera, OriginOS 6 and IP68/IP69 round out the spec sheet

On the rear, the phone uses a 50-megapixel GC50F6 sensor with autofocus. The front camera is an 8-megapixel unit, which keeps the imaging setup fairly straightforward for this class of device.

Charging is rated at 44W wired, which is important given the 10,000mAh battery inside. That battery size is unusually large for a phone that is still only 8.59mm thick, so the charging speed matters more than usual.

• Rear camera: 50MP GC50F6 with autofocus
• Front camera: 8MP
• Charging: 44W wired
• Battery: 10,000mAh
• Body thickness: 8.59mm

The software side is handled by OriginOS 6 based on Android 16. iQOO also gives the Z11S IP68 and IP69 resistance, which adds durability credentials that fit the phone’s endurance-first pitch.

The combination of a massive battery, high-refresh AMOLED panel, current software, and strong ingress protection places the Z11S in a very specific part of the market. It is aimed at buyers who want long battery life without giving up display quality or basic ruggedness.

For now, the key details are clear: the iQOO Z11S launched in China with a 10,000mAh battery, a Dimensity 7500 chip, and a starting price of CNY 1,999. The phone’s appeal is built around endurance, but the rest of the spec sheet shows iQOO is trying to cover more than one box.
