The answer depends on which vivo Y400 you mean and where you plan to buy. vivo Indonesia lists a Y400 with Snapdragon 685, while 91mobiles’ comparison calls its model the Y400 5G and lists Snapdragon 4 Gen 2. Those are not interchangeable specifications. Nothing’s Phone (4b) also varies by market, including battery capacity and price. Check the exact model and local listings before choosing; the available prices do not establish a universal price difference.
First, identify the exact vivo Y400
The name “vivo Y400” does not identify one consistently documented configuration in the available listings. vivo Indonesia’s official product page describes a Y400 with Snapdragon 685, Android 15, Funtouch OS 15, and 8 GB RAM with either 128 GB or 256 GB storage. By contrast, 91mobiles’ comparison identifies a vivo Y400 5G and lists Snapdragon 4 Gen 2. Do not combine the Indonesia page’s software and prices with the comparison entry’s 5G model specifications as though they were one phone.

Before comparing, check the full model name, country, connectivity variant, memory configuration, and warranty on the listing you intend to buy. The official vivo Indonesia Y400 page establishes the Indonesia-specific variant, not every phone sold under a Y400 name.

These are listed specifications, not test results. The cited material does not provide a like-for-like performance benchmark or battery endurance test, so chipset names, refresh rate, and battery capacity alone cannot establish which phone is faster or lasts longer in everyday use. Megapixel counts likewise do not prove which camera takes better photos.

Display, performance, and camera: what the numbers can tell you
Display
Nothing specifies a 6.77-inch Super AMOLED panel with adaptive refresh up to 120 Hz. The 6.67-inch AMOLED figure for the comparison’s vivo entry comes from 91mobiles, rather than the Indonesia product page. Confirm the display on the exact Y400 variant you are considering before treating the size difference as a direct comparison.
Performance
The vivo chipset discrepancy is the central performance caveat: Snapdragon 685 on the official Indonesia page versus Snapdragon 4 Gen 2 for 91mobiles’ Y400 5G entry. Nothing’s Snapdragon 6 Gen 4 listing gives a specification to compare, but no independent benchmark is supplied here. Do not infer a reliable real-world speed ranking from these names alone, particularly without confirming which Y400 is sold in your market.

Cameras
The available hardware descriptions list a 50 MP rear camera and 32 MP front camera for 91mobiles’ vivo entry. Nothing’s official page highlights a 50 MP main camera and 4K video. These figures describe different aspects of the camera systems; they are not evidence of image quality, low-light performance, stabilization, or video quality in practice.
Battery capacity and software vary by region
Nothing’s Malaysia product page lists a 5,200 mAh Phone (4b) battery, while the India configuration is listed at 6,000 mAh. Use the capacity for the specific country and configuration you are buying rather than treating one figure as universal. vivo’s 6,000 mAh figure in the comparison belongs to 91mobiles’ Y400 5G entry, not necessarily the Snapdragon 685 Indonesia model.

The available product information does not securely establish comparable update-policy durations for both phones and all markets; check each manufacturer’s local support terms if years of updates are a deciding factor.

For a meaningful local comparison, compare the same day’s prices in your country for matching storage tiers, then check seller, stock, taxes, warranty, and whether a price is a temporary discount. Nothing’s official regional listings are available for Spain and Malaysia; neither price should be treated as a global price.

Quick Recap
Best Value
- Compatible with Vivo Y400 Pro Phone Cases
- The phone case features a matte PU leather exterior with a TPU frame and magnetic plate, offering skin-friendly, slim, and comfortable materials.
- The screen edges and camera frame are fully wrapped with elevated protection to effectively prevent scratches. It withstands minor drops, bumps, and impacts.
- Soft-padded edges provide a comfortable grip and resist deformation. Built-in magnetic plate enables use with car mounts and other accessories.
- Stylish appearance meets precise cutouts, allowing full access to all ports and the camera. Buttons offer soft, responsive tactile feedback for effortless operation.
- Consider the vivo Y400 if the locally sold model’s confirmed specifications, storage option, software, and price suit your needs. Buyers in Indonesia can verify the Snapdragon 685 configuration and listed memory options on vivo’s official page.
- Consider the Nothing Phone (4b) if its locally available configuration, 6.77-inch 120 Hz display, and listed software are a better fit for your priorities and budget.
- Pause before comparing performance or battery life if the vivo listing only says “Y400” without clarifying whether it is the Snapdragon 685 model or the Y400 5G entry. Resolve that model mismatch first.
