Neither phone wins outright. The vivo Y400 5G has the better screen technology and much faster charging, while the iQOO Z11x 5G has a larger display, a bigger battery and, on the official store pages checked on 4 October 2026, a lower price for the same 8 GB + 128 GB storage configuration. The gap on those pages was ₹13,000. The right choice depends on whether you care more about display type and charging speed or about battery capacity and price.
Price difference: what the official stores showed
Prices in India change often, and stock can disappear without notice, so treat the figures below as a snapshot from 4 October 2026 rather than current prices. Both models were compared at the same 8 GB RAM and 128 GB storage level, which is the fairest basis for a price gap.
| Phone and variant | Price shown | Where it was shown | Status when checked |
|---|---|---|---|
| vivo Y400 5G, 8 GB + 128 GB, Olive Green | ₹40,999 | vivo India Store | Marked unavailable on the selected variant |
| iQOO Z11x 5G, 8 GB + 128 GB, Prismatic Green | ₹27,999 (MRP shown as ₹30,999) | iQOO India Store | Price shown; stock status not stated |
On these two official pages the difference is ₹13,000. Because the vivo variant was unavailable at capture, that figure describes list pricing at one moment, not a price you can currently buy at. A third-party comparison on 91mobiles showed a different Y400 price and the same ₹27,999 for the Z11x, so the Y400 figure varies by source. Check the live price and stock of the exact variant you want before deciding.

Full specifications are on the vivo India Y400 5G specifications page and the iQOO India Z11x product page.
Display: AMOLED against a larger LCD
The Y400’s main difference is its AMOLED panel. AMOLED screens light each pixel individually, which typically gives deeper blacks and higher contrast than an LCD. The Z11x’s LCD panel is slightly larger at 6.76 inches against 6.67 inches, and both support a 120 Hz refresh rate.

The brightness numbers are not directly comparable. vivo’s 1,800 nits is a local peak brightness figure, which applies to a small highlighted area. iQOO’s 1,200 nits refers to a high-brightness mode. Neither figure tells you how the screen will look in direct sunlight, and no independent side-by-side measurement was available for this comparison.

1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsPerformance: two different chip names
The Snapdragon 4 Gen 2 and the Dimensity 7400-Turbo are different chips from different makers, and the model names alone do not settle which is faster. The Dimensity 7400-Turbo is the newer and higher-tier of the two, so the Z11x may be expected to perform better on demanding tasks. However, no independent benchmark or like-for-like test of these two phones was available, so this article does not declare a winner. If speed is your main concern, look for reviews that run the same apps and games on both devices and report results from a named testing source.

Battery and charging: capacity against wattage
The Z11x offers a 7,200 mAh battery against the Y400’s 6,000 mAh typical capacity, while the Y400 charges at 90 W against the Z11x’s 44 W. These specs pull in opposite directions. A bigger battery stores more energy, but a faster charger can refill a smaller battery quickly. Neither spec on its own tells you how long a phone will last on a charge or how long a full charge will take, because those results depend on screen use, software, and the conditions of each test.
If you often plug in during short breaks, the Y400’s 90 W charging is the more practical advantage. If you tend to go long stretches without charging, the Z11x’s larger battery is the spec to weigh more heavily.

Cameras: matching resolution, unclear quality
Both phones list a 50 MP main rear camera with a 2 MP secondary sensor and a 32 MP front camera. The Z11x’s main sensor is identified as a Sony sensor, which the Y400’s page does not state. iQOO also advertises 4K recording at 30 fps on both front and rear cameras, and the Y400 pages checked do not list that specification.

Storage and memory options
Match the variant before comparing prices. The Y400 comes in 8 GB + 128 GB and 8 GB + 256 GB configurations. The Z11x comes in 6 GB + 128 GB, 8 GB + 128 GB and 8 GB + 256 GB. The 8 GB + 128 GB pairing is the one shared by both lines and the one used for the price figures above. The 6 GB model is the Z11x’s entry option, and its price was not captured here.
Software and update commitments
The Y400 runs Android 15 with Funtouch OS 15, and the Z11x runs OriginOS 6.0. The manufacturer pages checked do not state how many years of Android or security updates either phone will receive. If long-term updates matter to you, ask the seller or check each brand’s update policy before buying.
Durability ratings
vivo lists IP68 and IP69 ratings for the Y400. iQOO highlights IP69+ and describes the Z11x as military-grade. These are manufacturer claims, and each company may test under different conditions, so the labels cannot be compared directly. Neither rating is a guarantee against drops or long-term wear.

- Choose the vivo Y400 5G if you want an AMOLED screen, fast 90 W charging and a recent Snapdragon chip, and you can find the 8 GB + 128 GB variant at or near its listed price.
- Choose the iQOO Z11x 5G if you want a larger screen and the biggest battery capacity, and you are happy with LCD. It was also the lower-priced phone on the official pages checked.
- Check availability first. The Y400 variant was unavailable when checked, so a live stock check may change the decision.
- Do not decide on one number. Compare display, charging speed, battery capacity, price for the same variant, and stock before choosing.
