Design and Build Quality

At first glance, the iQOO Z11 looks premium despite its affordable pricing.

The smartphone features a modern design language with a clean rear panel and minimalistic camera module. Available in Cosmic Black and Glacier Blue, both color variants offer a sophisticated appearance.

Despite housing a gigantic 9020mAh battery, iQOO has managed to keep the thickness at 8.3mm, which is impressive. However, the device weighs 213 grams, making it slightly heavier than typical mid-range smartphones.

Design Highlights

• Premium build quality
• Slim profile considering battery size
• Comfortable curved edges
• Modern punch-hole display
• IP68 water and dust resistance
• In-display fingerprint scanner

The IP68 certification is especially noteworthy because many competitors in this price range still lack proper water resistance.

Design Rating: 9/10

Display: One of the Best in the Segment

The display is undoubtedly one of the strongest aspects of the iQOO Z11.

It features a massive 6.83-inch AMOLED panel with a sharp 1260 × 2800 resolution and an ultra-smooth 144Hz refresh rate.

Why the Display Stands Out

The AMOLED technology ensures:

• Deep blacks
• Excellent contrast
• Vibrant colors
• Better power efficiency

The 144Hz refresh rate makes scrolling, gaming, and animations feel incredibly smooth.

Brightness Performance

The display offers:

• 800 nits typical brightness
• 2000 nits HBM brightness
• 5000 nits peak brightness

This makes outdoor visibility excellent even under direct sunlight.

HDR Experience

HDR support enhances streaming experiences on supported platforms, delivering richer colors and improved dynamic range.

Eye Protection Features

The 2160Hz PWM dimming technology reduces eye strain during nighttime usage.
