Should I choose iQOO Z11 or Z11X?

Verdict: Choose the iQOO Z11 first, as it offers a substantially superior 1.5K 165Hz AMOLED display, more powerful Dimensity 7500 Turbo processing with a 3,800 mm² vapor chamber, faster 90W charging with up to 9,020mAh capacity, OIS camera stabilization, and an extra year of OS upgrades.

The iQOO Z11 is the superior all-around smartphone over the iQOO Z11x, offering a faster 165Hz 1.5K AMOLED display, stronger Dimensity 7500 Turbo performance, quicker 90W charging, and longer software support.

The iQOO Z11 outperforms the iQOO Z11x across nearly every core metric, beginning with its 6.83-inch 1.5K curved AMOLED display running at 165Hz compared to the Z11x's smaller 6.76-inch 120Hz IPS LCD screen. Under the hood, the iQOO Z11 features the MediaTek Dimensity 7500 Turbo paired with a dedicated 3,800 mm² vapor chamber cooling system, outpacing the Z11x's MediaTek Dimensity 7400 Turbo. In terms of power, the iQOO Z11 offers battery options reaching up to 9,020mAh with 90W fast charging, outmatching the Z11x's 7,200mAh capacity and 44W FlashCharge speeds. While the iQOO Z11x offers MIL-STD-810H shock resistance and a 32MP 4K front selfie camera, the iQOO Z11 remains the better long-term investment with its OIS-enabled 50MP Sony IMX882 rear sensor, IP68/IP69 ratings, and 3 years of guaranteed Android OS updates versus just 2 years on the Z11x.

Best for iQOO Z11

  • Users who want a smoother, higher-resolution 6.83-inch 1.5K curved AMOLED display with a 165Hz refresh rate
  • Heavy gamers needing the faster MediaTek Dimensity 7500 Turbo chipset backed by a 3,800 mm² vapor chamber cooling system
  • Consumers seeking superior battery endurance and speed with up to 9,020mAh capacity and 90W fast charging
  • Photographers prioritizing steady low-light shots via the 50MP Sony IMX882 rear sensor with Optical Image Stabilization (OIS) and an 8MP ultra-wide lens
  • Long-term buyers looking for extended 3-year Android OS upgrade support and robust IP68/IP69 water and dust ingress protection

Best for Z11X

  • Selfie enthusiasts and vloggers who prioritize a higher-resolution 32MP front camera with 4K video recording
