iQOO Z11 5G Review: The Mid-Range Gaming Phone That Nobody Expected to Have a 9020mAh Battery

The iQOO Z11 5G does not arrive trying to compete with the iQOO 15R. It has a different job. At RM2,199 for the 12GB variant, it sits in the bracket where buyers are choosing between adequate-and-affordable and surprisingly-capable — and the Z11 makes a strong case for the latter. The battery capacity alone warrants serious attention. The gaming credentials back it up. The camera asks you to manage your expectations, which is not an unreasonable request from a phone at this price.

We tested it across three titles at demanding settings, ran an LLM inference benchmark to understand where the chip stands for local AI workloads, and confirmed one feature that iQOO does not officially document. Here is the honest account.

What We Like About the iQOO Z11 5G

Gaming Performance That Earns the Label

The Snapdragon 7s Gen 4 is a mid-range chip, and it delivers mid-range performance — which, in 2026, is more than enough for the titles most Malaysian mobile gamers actually play.

Mobile Legends: Bang Bang at maximum resolution runs smoothly throughout. MLBB is not a particularly demanding benchmark, but max-settings stability confirms the baseline without caveat. More telling is Where Winds Meet at Ultra quality with TAA anti-aliasing enabled, memory optimisation on, and the heaviest graphical load options active — bloom optimisation, ultra-distance shadows, underwater terrain — all running simultaneously. The Z11 handled it without stuttering or frame drops. For a mid-range chip, that is a legitimate result.

War Thunder is the interesting case. Ray tracing is not currently available as an option in the game on this hardware. The Snapdragon 7s Gen 4 supports ray tracing at the silicon level, and the expectation is that a software update will unlock the option in a future War Thunder patch. For now, the game runs smoothly in its current state. The ray tracing story is a coming attraction rather than a present feature — worth flagging, but not a mark against the phone for what it delivers today.

A 9020mAh Battery That Changes the Conversation

This is the number that makes you look twice at the spec sheet. 9020mAh. In a phone that is thin and light enough to hold comfortably.

The technology behind it is iQOO’s BlueVolt 4th-generation silicon anode battery — the same fundamental chemistry that powers the iQOO 15R’s 7600mAh cell, applied here in a larger configuration. Silicon anodes store approximately ten times more lithium per unit of volume than conventional graphite anodes, which is how a capacity this large fits inside a phone that does not feel like carrying a power bank.

The result in real-world testing: 17 hours and 26 minutes of battery life. That number puts the Z11 comfortably ahead of anything in its class. A full Malaysian day — morning commute, working hours, evening gaming session — and you are not reaching for a charger. That is the outcome that matters.

The 5-year battery health guarantee is a meaningful commitment alongside the capacity figure: the cell is rated to retain at least 80% capacity through five years of charge cycles. For buyers making a two-to-three year phone commitment, that runway gives the Z11’s battery story a long tail.

The 90W FlashCharge brings the large cell back to full in a timeframe that does not punish you for actually using it.

Cooling That Takes the Job Seriously

The 7,000mm² IceCore vapour chamber cooling system is the largest in this price bracket. The result during testing was consistent: no meaningful heat build-up during sustained gaming sessions, including the Where Winds Meet ultra-settings run. The phone stayed comfortable in hand throughout.

Thermal management at this level is not common in the sub-RM2,500 bracket. The Z11 handles it better than its price suggests it should.

A Display Built for What the Phone Does

The 6.83″ 1.5K AMOLED at 144Hz is the right display for a gaming phone at this price. The panel delivers fine detail, punchy colour, and the high refresh rate that makes fast-paced gaming feel responsive. There is nothing on this screen that undermines the gaming experience — content is sharp, motion is smooth, and the size gives you real estate without tipping into unwieldy.

What We Don’t Like About the iQOO Z11 5G

The DDR4 RAM Shows Its Tier Against Faster RAM

The Snapdragon 7s Gen 4 in iQOO Z11 5G is paired with LPDDR4X RAM — the previous-generation memory standard — at 12GB. For gaming and daily use this is sufficient. For AI inference workloads, the bandwidth ceiling is visible.

We ran the Qwen 9B model through MNN Chat with our standard prompt (“Tell me about nuclear fusion power and its implications for clean energy”). The results:

The Z11 can run a 9B model locally — that capability is real and worth acknowledging. At 2.43 t/s decode, however, the experience is patient work rather than fluid conversation. The LPDDR5X advantage on the competing chip is significant for inference throughput. If local LLM workloads are part of your use case, the Z11 handles them, but not quickly.

This is not a surprise for a mid-range chip with previous-generation memory. It is worth stating plainly for buyers who care about it.

Camera Is Minimal — Which Is Fine, Until It Isn’t

The 50MP Sony IMX882 aspherical main lens paired with a 2MP depth/bokeh sensor is a camera system that fulfils a brief and nothing more. Daylight stills are competent. The Sony sensor produces clean enough output for standard social use and documentation. There is no telephoto, no ultrawide of meaningful quality, and no pretension that this is a camera phone.

For a device positioned as a gaming phone at RM2,199, the camera package is appropriate. It shoots what you need it to shoot. It will not replace your dedicated camera for travel or event coverage, and it was never intended to. Buyers cross-shopping on imaging capability should be steered toward other options. Buyers who understand what the Z11 is built for will not find the camera a dealbreaker.

Verdict

The iQOO Z11 5G is a gaming phone that knows exactly what it is — and executes on it with unusual conviction for the price. The 9020mAh battery is the headline that survives scrutiny: 17-plus hours of tested life, silicon anode longevity, bypass charging confirmed under testing, and 90W speed to refill it. The Snapdragon 7s Gen 4 runs demanding titles at high settings without thermal drama, backed by a 7,000mm² cooling system that keeps the experience comfortable throughout.

The ceiling is visible: LPDDR4X memory limits AI inference throughput, the camera offers sufficiency rather than ambition, and War Thunder ray tracing remains a future feature pending a software update. None of those define the daily experience for the buyer this phone is built for.

At RM2,199, the iQoo Z11 5G punches above its weight. For Malaysian buyers who want sustained gaming performance, genuine all-day battery life without compromise, and a build that takes thermals seriously — this phone earns a clear recommendation.
