The iQOO Z11S takes a different approach to the modern mid-range smartphone. Instead of chasing the fastest charging or the most versatile camera system, it puts a 10,000mAh battery at the center of the experience.
That large battery is paired with a 6.83-inch AMOLED display with a 144Hz refresh rate, MediaTek’s Dimensity 7500 chipset, UFS 3.1 storage, and IP68/IP69 protection. On paper, this gives the Z11S a strong combination of endurance, display quality, performance, and durability.
The trade-offs are just as clear. Charging is limited to 44W, the rear camera is a single 50MP sensor, and the phone weighs 225g. More importantly, independent testing shows that its large battery does not automatically translate into class-leading endurance, while sustained gaming performance still has some room for optimization.
So the Z11S is not simply a phone with a huge battery. Its real appeal depends on how well its display, performance, battery life, charging speed, and durability work together in everyday use.

Key Takeaways
- 10,000mAh is the defining hardware feature.
- The 6.83-inch 144Hz AMOLED display is one of the phone’s strongest components.
- The Dimensity 7500 delivers solid mid-range performance.
- UFS 3.1 storage is a useful advantage for app loading and file operations.
- IP68/IP69 protection gives the phone a higher level of water and dust resistance than many conventional mid-range devices.
- The rear camera setup is simple: one 50MP main camera.
- 44W charging is relatively modest for a 10,000mAh battery.
- The phone weighs 225g, which is noticeable but reasonable considering its battery capacity.
- AnTuTu’s tested 12GB + 512GB model reached 1,118,494 points in its highest result from three runs.
Design & Build
The iQOO Z11S measures 163.90 × 76.50 × 8.59mm and weighs 225g. Those numbers make it a large phone, but the 8.59mm thickness is relatively restrained considering the 10,000mAh battery inside.
The rear design uses a nano-level lithography process that creates a changing light pattern across the back. The camera module follows iQOO’s floating-window-inspired design, giving the phone a more distinctive appearance than a basic flat camera island.
The phone also uses relatively narrow bezels. In AnTuTu’s measurements, the bottom bezel was around 1.86mm, while the top and side bezels were around 1.35mm.
Durability is another important part of the design. The Z11S carries IP68 and IP69 ratings, covering dust resistance and protection against different forms of water exposure. It also includes a water and dust drainage feature that uses sound vibrations to help clear the speaker and earpiece.
The main compromise is weight. At 225g, the Z11S is considerably heavier than lightweight mid-range phones. That’s the price of carrying a 10,000mAh battery without making the body excessively thick.
Display
The Z11S has a 6.83-inch AMOLED display with a 2800 × 1260 resolution and up to 144Hz refresh rate. It supports 1.07 billion colors, P3 color gamut, HDR, and an advertised 8,000,000:1 contrast ratio. The screen-to-body ratio is 94.47%.
The high refresh rate is useful for everyday interaction. Scrolling through websites, social media feeds, and system menus should look smoother than on a conventional 60Hz panel. Supported games can also take advantage of higher frame rates, although the 144Hz panel does not mean every game will actually run at 144fps.
Brightness is rated at up to 2,000 nits full-screen, while manual brightness can reach 1,000 nits. In AnTuTu’s testing, the display measured approximately 795 nits when manually set to maximum brightness.
For users who spend a lot of time reading or using the phone at night, the display also uses 2160Hz high-frequency PWM combined with full-brightness DC-like dimming. The display has also received low-blue-light and low-flicker certifications.
For everyday use, the display is one of the Z11S’s strongest areas. It combines a large viewing area, high resolution, AMOLED contrast, and a high refresh rate without relying on an LCD panel.
Performance
The iQOO Z11S uses the MediaTek Dimensity 7500, manufactured on a 4nm process. Its CPU combines four Arm C1 Pro cores running at up to 2.6GHz with four Arm C1 Nano cores at 2.0GHz, while graphics are handled by the Mali-G625 GPU.
Memory configurations include 8GB and 12GB of LPDDR4X RAM, while storage uses UFS 3.1. Available configurations are 8GB + 128GB, 8GB + 256GB, 12GB + 256GB, and 12GB + 512GB. There is no microSD slot.
AnTuTu Performance
AnTuTu tested the 12GB + 512GB version with the phone at around 25°C, 300-nit brightness, and performance mode enabled.
Across three runs, the highest score was:
- Total: 1,118,494
- CPU: 451,835
- GPU: 108,424
- MEM: 209,536
- UX: 348,699
A separate ten-run sustained test without cooling produced an average score of 1,188,832, while the anti-cheat result was 1,002,495. These figures came from different testing procedures, so they should not be treated as interchangeable benchmark results.
The same storage test recorded sequential read speeds of approximately 1,980.4MB/s and sequential write speeds of 1,806.3MB/s.
For normal use, the Dimensity 7500 and UFS 3.1 combination gives the Z11S enough hardware for demanding applications, multitasking, media consumption, and gaming.
Gaming Performance
The gaming results are less straightforward.
In AnTuTu’s 30-minute Honor of Kings test at the highest image quality, the phone averaged 109fps, while the 1% low was 54fps. The game itself supported up to 120fps on the device, rather than the display’s full 144Hz capability.
The tester repeated the test several times and reported frame-rate drops during intense team fights. Temperatures reached 42.1°C on the front and 40.9°C on the rear.
This does not mean the Z11S lacks gaming performance. The Dimensity 7500 has enough power for demanding games, but sustained gaming behavior depends heavily on software optimization and thermal management.
That distinction matters more than the peak benchmark score for anyone buying the phone primarily for gaming.
Software
The iQOO Z11S runs Android 16 with OriginOS 6.
The software includes iQOO-specific performance and gaming features, including its AI Esports Signal Engine 2.0. The phone also supports Memory Fusion, allowing the 8GB model to expand virtually to up to 16GB and the 12GB version to up to 24GB. This does not replace physical RAM, but it can provide additional virtual memory for multitasking.
iQOO also states that the Z11S has passed a 60-month lasting fluency certification, which is intended to address long-term system smoothness. This is a manufacturer-related certification rather than a guarantee that every user will experience identical performance after five years.
The software experience therefore looks reasonably well matched to the hardware, although the gaming results show that optimization remains an important factor. The reported frame-rate instability in Honor of Kings suggests that future firmware updates could still affect sustained performance.
Camera
The camera system is considerably simpler than the rest of the phone.
The rear setup consists of a single 50MP f/1.8 camera with a CMOS sensor, autofocus, and video stabilization. The front camera is 8MP with an f/2.05 aperture.
Video recording includes:
- 4K at 30fps
- 1080p at 60fps
- 1080p at 30fps
- Slow motion
- Live Photo
- Motion capture
- AI imaging
- Super Night Scene
The front camera supports 1080p video recording at 30fps.
The hardware is straightforward rather than versatile. There is no dedicated ultrawide or telephoto camera, so users who frequently shoot landscapes, large groups, or distant subjects will have fewer framing options.
For buyers who mainly take standard photos and videos, the 50MP main camera covers the basic requirements on paper. However, camera versatility is clearly not one of the Z11S’s main selling points.
Battery & Charging
Battery life is where the Z11S separates itself from most conventional mid-range phones.
The device uses a 10,000mAh single-cell battery, with a rated capacity of 9,800mAh. The typical energy capacity is 37.30Wh, while the rated energy capacity is 36.56Wh.
iQOO says the battery uses its Blue Ocean battery technology and a compact internal packaging design that helps fit the large cell into an 8.59mm-thick body.
Battery Life Testing
AnTuTu tested the phone for six hours under a mixture of demanding tasks. Battery consumption was:
| Activity | Battery Used |
| 1 hour local 4K video | 0% |
| 1 hour video call | 6% |
| 1 hour TikTok | 6% |
| 1 hour Weibo | 9% |
| 1 hour Taobao | 8% |
| 1 hour Honor of Kings | 11% |
After six hours, the phone had 60% battery remaining.
A separate three-hour Honor of Kings test consumed 28%, leaving 72% remaining.
Those are strong absolute numbers, but the results also show why battery capacity alone should not determine expectations. AnTuTu reported that the phone did not achieve a top-ten position in its six-hour battery comparison, despite having a 10,000mAh battery.
In other words, the battery is enormous, but the software and power management do not always extract as much advantage from that capacity as the specification might suggest.
Charging Speed
The Z11S supports 44W charging, along with PD, PPS, and UFCS compatibility. It also supports wired reverse charging and Global Direct Power Supply 2.0.
AnTuTu’s charging test produced the following results:
| Time | Battery |
| 10 minutes | 13% |
| 30 minutes | 33% |
| 50 minutes | 50% |
| 60 minutes | 60% |
| 80 minutes | 79% |
| 90 minutes | 89% |
| 100 minutes | 98% |
| 105 minutes | 100% |
The test therefore required 1 hour and 45 minutes to go from 1% to 100%.
This is the clearest trade-off in the battery system. The Z11S can spend a long time away from the charger, but when the battery is finally low, refilling 10,000mAh is not particularly quick.
Connectivity & Extras
The Z11S has a broad connectivity package.
It supports 5G, Wi-Fi 6, Bluetooth 5.4, NFC, USB Type-C 2.0, OTG, GPS, BeiDou, GLONASS, Galileo, QZSS, and NavIC. It also includes an IR remote function.
Audio is handled through stereo speakers, while wired headphones use the USB-C port because there is no 3.5mm headphone jack. The USB port supports digital Type-C headphones. Bluetooth audio codecs include SBC, AAC, aptX, aptX HD, and LDAC.
Security features include an under-display optical fingerprint scanner and Face Wake. The phone also has a physical gyroscope and an X-axis linear motor.
The main limitation here is USB 2.0. It is sufficient for charging and everyday connectivity, but users who frequently transfer large files will get slower wired transfer speeds than with a USB 3.x interface.
Competitors
The Z11S is difficult to compare directly with conventional mid-range phones because its hardware priorities are unusual.
Most similarly priced phones tend to distribute their hardware budget differently. Some put more emphasis on cameras and faster charging, while others use smaller batteries to keep weight down.
The Z11S instead puts a large portion of its hardware into battery capacity, display quality, durability, and sustained everyday use.
That makes the comparison straightforward from a buyer’s perspective:
- If battery capacity is a major priority, the Z11S has a clear hardware advantage.
- If camera versatility matters more, a phone with multiple rear cameras may make more sense.
- If charging speed is important, 44W is unlikely to be the main reason to choose the Z11S.
- If weight matters, 225g should be considered before buying.
- If display quality matters, the 144Hz AMOLED panel makes the Z11S more competitive.
The right comparison therefore depends heavily on which part of the smartphone experience matters most to the buyer.
Price & Value
The iQOO Z11S launched in China at the following official prices:
| Configuration | Official China Price |
| 8GB + 128GB | ¥1,999 |
| 8GB + 256GB | ¥2,199 |
| 12GB + 256GB | ¥2,499 |
| 12GB + 512GB | ¥2,899 |
These are the official Chinese retail prices, not global prices. International pricing and availability can differ depending on the market.
At these prices, the Z11S is mainly selling a combination of features rather than one standout specification alone. The 10,000mAh battery gets the most attention, but buyers are also getting a 144Hz AMOLED display, Dimensity 7500, UFS 3.1 storage, IP68/IP69 protection, NFC, Wi-Fi 6, and stereo speakers.
The compromises are equally important: 44W charging, a single rear camera, 8MP selfie camera, USB 2.0, and a 225g body.
The 12GB + 256GB version is the middle configuration that avoids paying for the 512GB model while providing the higher RAM tier. The 512GB version makes more sense for users who expect to keep large games, videos, and other files locally because there is no microSD slot.

Final Verdict
The iQOO Z11S has a clear identity.
It is a battery-focused smartphone that also takes its display and everyday performance seriously. The 10,000mAh battery is supported by a 6.83-inch 144Hz AMOLED panel, Dimensity 7500 chipset, UFS 3.1 storage, stereo speakers, and IP68/IP69 protection.
The battery capacity is impressive, but there is an important qualification. Independent testing showed strong absolute endurance, yet the phone did not lead AnTuTu’s broader six-hour battery comparison. Gaming also exposed some optimization issues, with an average of 109fps and a 54fps 1% low in Honor of Kings, alongside temperatures above 40°C.
Charging is another compromise. A 10,000mAh battery paired with 44W charging means the Z11S can last a long time, but it takes around 105 minutes to recharge fully in the tested scenario.
The camera system is similarly focused on simplicity rather than versatility. A 50MP main camera can handle the basic hardware requirements, but the lack of ultrawide and telephoto cameras limits the range of shooting options.
For the right user, that trade-off makes sense. The Z11S is most interesting if battery capacity, display quality, durability, and everyday performance matter more than camera versatility, charging speed, or low weight.
