The Y400 has an AMOLED display and 90 W charging. The Z11x has a slightly larger LCD screen, a higher stated battery capacity, and a newer-named MediaTek chipset. At the prices shown on the two Indian official stores when checked on 4 October 2026, the Z11x was about ₹13,000 cheaper for the 8 GB + 128 GB configuration. That gap is a store-page observation, not a stable market price, so confirm it before buying.
Specs at a glance
The table below uses the figures published on each brand’s Indian product or specification page. Where a page does not state a value, the table says so rather than filling the gap from another source.

The Y400’s main practical advantage is its AMOLED panel. AMOLED screens light each pixel individually, which usually means deeper blacks and higher contrast than an LCD of similar brightness. The Z11x’s LCD is slightly larger, at 6.76 inches against 6.67 inches, and both phones list 120 Hz refresh rates.

The brightness figures are not directly comparable. vivo quotes 1,800 nits as a local peak value, while iQOO quotes 1,200 nits in a high-brightness mode. Each company defines its own measurement, and neither figure comes from an independent lab test. If you read sunlight legibility as a priority, look for side-by-side reviews under the same conditions before deciding.
Battery and charging
The Z11x has the larger stated battery at 7,200 mAh, compared with the Y400’s 6,000 mAh typical rating. The Y400 charges at 90 W, roughly twice the 44 W rating on the Z11x.

These numbers answer different questions. Battery capacity indicates how much energy the cell can hold, while charger wattage indicates how quickly the phone can take power under the vendor’s conditions. Neither one tells you how many hours of screen-on time you will get, or how long a full charge takes in day-to-day use. Those results depend on screen settings, network conditions and workload. The vendor pages we checked do not include controlled runtime or charge-time figures.
Performance: chipsets with different naming
The Y400 uses the Snapdragon 4 Gen 2, a Qualcomm chip in its entry to mid-range line. The Z11x uses the MediaTek Dimensity 7400-Turbo. The name suggests a newer, higher-tier part on the MediaTek side, but a model name alone does not establish which phone is faster in gaming, multitasking or sustained use.

No independent benchmark result comparing these two specific handsets was available when this article was prepared. Treat any single benchmark score you see, including scores quoted in vendor marketing, as a starting point rather than proof.
Cameras
Both phones list a 50 MP main rear camera with a 2 MP secondary sensor and a 32 MP front camera. The Z11x specification identifies its main sensor as a Sony unit, while the Y400 page does not name its sensor supplier. Megapixel counts say little about image quality, because sensor size, lens, processing and night mode matter at least as much.

iQOO states that the Z11x can record 4K video at 30 fps on both its front and rear cameras. The Y400 page reviewed does not state its video recording limits, so a like-for-like video comparison is not possible from the specifications alone.

The Y400 runs Android 15 with Funtouch OS 15, and the Z11x ships with OriginOS 6.0. The two interfaces differ in look and in preinstalled apps, so try to view a few screenshots before you decide which one suits you. Neither vendor page states how many years of OS or security updates each phone will receive, and that matters for a phone you plan to keep for several years.

Both phones carry water and dust ratings. vivo lists IP68 and IP69 for the Y400. iQOO highlights IP69+ and describes the Z11x as having military-grade durability. These are manufacturer claims. The pages do not identify the test standards behind the terms “military-grade” or “IP69+”, so the ratings should not be read as equivalent.
Price difference
The comparison is cleanest when both phones are matched on storage and RAM. The table below shows the figures observed on each official Indian store on 4 October 2026.
| Model and variant | Price observed | Source and status |
|---|---|---|
| vivo Y400 5G, 8 GB + 128 GB, Olive Green | ₹40,999 | vivo India Store; the selected variant was marked unavailable at the time of access |
| iQOO Z11x 5G, 8 GB + 128 GB, Prismatic Green | ₹27,999 (MRP shown as ₹30,999) | iQOO India Store |
On those two store pages, the Z11x was ₹13,000 cheaper than the Y400 for the 8 GB + 128 GB configuration. The Z11x also comes in a 6 GB + 128 GB version, which the Y400 does not offer, so the 8 GB comparison above is the fairest match.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Treat these figures with caution. Prices change with stock, promotions, bank offers and retailer, and a listed variant may be out of stock. A third-party comparison page at 91mobiles showed a different Y400 price and a ₹27,999 Z11x price. Its summary text also contains contradictory statements, including about battery life, so this article does not rely on that page for any figure. Check the current price on each official store, and on any other retailer you plan to use, before you buy.
Which one should you choose?
- Choose the vivo Y400 if you want an AMOLED screen, fast 90 W charging, and a 256 GB storage option, and you are prepared to pay more for the 8 GB + 128 GB version on the observed store prices.
- Choose the iQOO Z11x if you want a larger screen and a higher stated battery capacity, you can accept 44 W charging, and you want the lower observed price for a matched 8 GB + 128 GB configuration.
- Before buying either, confirm the live price and stock for your chosen variant, compare the update promises on each brand’s support pages, and look for independent reviews that test battery life and performance under the same conditions.
Specs and store prices can settle the spec-sheet questions, but not every question. Use the table above to narrow the choice, then let your own priorities decide between a better-looking screen and a bigger battery.
