iQOO Z11 Review: 9,020mAh Battery, 165Hz AMOLED & Dimensity 8500 — Is It Worth Buying?

iQOO has been steadily carving out a reputation for delivering value-packed smartphones, and the new iQOO Z11 might be its boldest move yet. Launched in China in late March 2026 at a starting price of CNY 1,999 (approximately Rs 27,300), the Z11 introduces two milestones for the brand: the largest battery ever fitted into an iQOO device at 9,020mAh, and the brand's first-ever 165Hz AMOLED display. Paired with a Dimensity 8500 chipset and a slim 8.3mm chassis, this phone is making waves in the mid-range segment — and we are here to find out whether the real-world experience matches the spec sheet.

Quick Specifications at a Glance

Display: iQOO's First 165Hz AMOLED

The iQOO Z11 sports a 6.83-inch AMOLED panel with a 1.5K resolution of 2800×1260 pixels — a meaningful step up from the 1080p screens typically found at this price tier. The headline number here is the 165Hz refresh rate, a first for any iQOO handset. In practice, this translates to noticeably smoother scrolling, fluid gaming, and animations that feel closer to flagship-grade than mid-range.

The display reaches a peak brightness of 5,000 nits, making outdoor readability excellent even under harsh sunlight. iQOO has also equipped the panel with 2160Hz PWM dimming and DC-like dimming, both aimed at reducing eye strain during extended use — a thoughtful inclusion for users who spend long hours gaming or streaming. Touch sampling rate sits at 300Hz, which provides snappy and accurate input registration during fast-paced games.

Performance: Dimensity 8500 Holds Its Own

MediaTek's Dimensity 8500 is built on a second-generation 4nm process and uses an all-large-core (Cortex-A725) architecture, prioritising efficiency without sacrificing raw power. iQOO layers on its Monster Over-Core Engine, which includes a Prophet Scheduler for smarter background task management and a Lightning Accelerator to stabilise frame rates under gaming loads. The company claims an AnTuTu benchmark score exceeding 2.62 million, which places it solidly in the upper mid-range tier.

Thermal performance is managed by a 7K Ice Dome VC liquid cooling system, and in sustained gaming sessions, the phone remained warm but never uncomfortably hot. Day-to-day tasks like multitasking between apps, editing photos, and streaming 4K content felt seamless across all RAM configurations. The UFS 4.1 storage means fast app installs, snappy app launches, and speedy file transfers compared to the UFS 3.1 found on many rivals at this price point.

Camera: Competent, Not Extraordinary

The iQOO Z11 makes do with a dual rear camera setup — a 50MP Sony LYT-600 primary sensor with Optical Image Stabilisation (OIS) and a 2MP depth sensor. The main camera handles daylight photography well, producing detailed images with accurate colours and controlled noise. OIS is a welcome addition at this price point, ensuring sharper handheld shots in lower light conditions.

The 16MP front camera is a reasonable performer for selfies and video calls. However, the omission of an ultrawide camera is a notable trade-off, one that many buyers at this segment will feel. On the video side, 4K recording is supported, and footage is stabilised adequately for casual use. Software features include portrait enhancements, film filters, and a watermark system that logs time and location — useful for travel photography.

Battery: The Undisputed Star of the Show

9,020mAh is not a number you see every day. iQOO has used fourth-generation silicon anode cells and semi-solid-state battery technology to pack this enormous capacity into a body that is just 8.25mm thick — an engineering feat that deserves genuine credit. The company claims over 10 hours of mixed usage with more than 50% charge remaining, and in real-world conditions, two-day battery life is very achievable for moderate users.

Charging at 90W is fast enough to top up this massive cell in a reasonable time, though not class-leading given the capacity. OTG reverse charging is also supported, allowing the Z11 to act as a power bank for other devices. For users who frequently travel without access to a charger or power users who game and stream heavily, this battery alone makes the Z11 a compelling proposition.

Software: Android 16 with OriginOS 6

The iQOO Z11 ships with Android 16-based OriginOS 6 out of the box. The software is clean and feature-rich, with AI tools, gaming enhancements, and a smooth interface. Features like Circle to Search and AI Creation tools are present, adding practical daily utility. The gaming-oriented additions — including AI Game Voice Changer and 4D Game Vibration — round out a software suite well-suited to its target audience of power users and gamers.

Head-to-Head Comparison: iQOO Z11 vs the Competition

To give you a clearer picture of where the Z11 sits in the current market, here is how it stacks up against four key rivals — ranging from an ultra-premium flagship camera phone to a budget mid-ranger.

What the Comparison Tells Us

iQOO Z11 vs Xiaomi 17 Ultra

These two phones exist in entirely different price universes. The Xiaomi 17 Ultra is a genuine ultra-flagship with a 1-inch Leica camera sensor, mechanical optical zoom, Snapdragon 8 Elite Gen 5, and wireless charging — but it costs five times more than the Z11. The Z11 cannot match the 17 Ultra on camera versatility, chipset raw power, or premium build, but it obliterates it on battery capacity: 9,020mAh vs 6,000mAh. The Z11 also edges ahead on display refresh rate (165Hz vs 120Hz). If you want the best camera money can buy, go Xiaomi. If you want a phone that lasts two days on a charge at a fraction of the price, the Z11 wins easily.

iQOO Z11 vs Vivo X300 Ultra

The Vivo X300 Ultra is a professional photography powerhouse with Zeiss optics, a 200MP quad-camera system, and a snap-on 400mm telephoto extender. It is priced at roughly ₹75,000–80,000. The Z11 and X300 Ultra share the same parent company (vivo), which means they run similar software (OriginOS 6), but that is where the similarities end. In terms of battery, the Z11 actually carries more capacity (9,020mAh vs 6,600mAh). However, the X300 Ultra is clearly the better device for imaging and overall premium experience. The iQOO Z11 offers incredible value for everyday users; the X300 Ultra is for dedicated mobile photographers.

iQOO Z11 vs Realme 16

This is the most direct segment comparison. Both phones target budget-conscious buyers, though the Z11 is priced slightly higher. The Realme 16 brings a lighter build (183g vs 216.5g), a microSD card slot, and a 7,000mAh battery. However, the iQOO Z11 counters with a significantly more powerful Dimensity 8500 chip (vs Dimensity 6400 Turbo), a faster 165Hz display (vs 120Hz), a superior main camera sensor (Sony LYT-600 with OIS vs standard 50MP), faster UFS 4.1 storage (vs UFS 2.2), and a much larger 9,020mAh battery. The Z11 is the stronger choice for performance and longevity; the Realme 16 is lighter and more pocketable for casual users.

iQOO Z11 vs Infinix Note 60 Pro

The Infinix Note 60 Pro competes directly in the ₹20,000 mid-range band and brings a 1.5K 144Hz AMOLED display, a 6,500mAh battery with 90W charging, and a Snapdragon 7s Gen 4 chip. The Z11 pulls ahead on chipset performance (Dimensity 8500 is meaningfully faster than Snapdragon 7s Gen 4), battery capacity (9,020mAh is nearly 40% larger), storage speed (UFS 4.1 vs UFS 2.2), and display refresh rate (165Hz vs 144Hz). The Infinix Note 60 Pro has a slightly better selfie camera (32MP vs 16MP) and is competitive on price. Overall, the Z11 offers a more complete package for performance-focused buyers.

Pros & Cons Summary

Final Verdict

The iQOO Z11 is one of the most ambitious mid-range smartphones of 2026. Its 9,020mAh battery is genuinely class-defining — nothing at this price point comes close. The 165Hz AMOLED display is a leap forward for the Z-series. The Dimensity 8500 chip handles all tasks comfortably, and the UFS 4.1 storage adds tangible everyday speed. The dual camera setup does its job without excelling, and the 16MP selfie camera is modest by 2026 standards.

When placed next to the Xiaomi 17 Ultra and Vivo X300 Ultra, the Z11 cannot compete on camera or premium credentials — but at less than a quarter of the price, it was never meant to. Against the Realme 16 and Infinix Note 60 Pro, it wins decisively on the specs that matter most: raw performance, display quality, battery life, and storage speed.

Who should buy it? The iQOO Z11 is ideal for heavy users — gamers, commuters, travellers, and content consumers — who want premium-feeling performance without a premium price tag. If and when it launches in India, expect it to be one of the most talked-about value phones of the year.
