Where the S2 has an advantage
Larger, higher-resolution display
On the published specifications, the S2’s 6.83-inch 1.5K panel is both larger and higher-resolution than the Y400’s 6.67-inch FHD+ display. Both list refresh rates up to 120 Hz. That makes the S2 the more compelling specification-sheet choice if screen size and resolution are priorities; the figures alone do not establish differences in brightness, colour accuracy or outdoor readability.
Rank #2
- Compatible with Vivo Y400 5G 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.
Higher stated battery capacity
vivo lists a typical 7050 mAh battery for the S2 and 6000 mAh for the Y400. The larger capacity does not, by itself, prove longer battery life: actual endurance depends on usage and other factors, and no independent, comparable battery test is established here.
Software support stated by vivo
The S2 product page states three generations of OS updates and five years of security updates. The cited Y400 store specifications identify Funtouch OS 15 but do not state a comparable update commitment, so the available page information does not support a like-for-like support-duration comparison.
Rank #3
- Compatible with vivo Y400 5G Phone Case Cover
- Magnetic ring design. Compatible with most wireless magnetic products on the market, such as wireless chargers, magnetic car mounts, magnetic batteries, and magnetic wallets.
- The phone case features a dual-layer TPU+PU construction for a comfortable, non-slip feel. Corner airbags provide drop protection to safeguard your device.
- Perforated design enhances airflow for accelerated heat dissipation. Precise cutouts ensure full functionality of all ports, buttons, and cameras.
- Raised edges around the screen and rear camera elevate these components off the surface, effectively protecting them from scratches.
Where the Y400 has an advantage
Faster listed charging
The Y400 lists 90 W FlashCharge, compared with 44 W for the S2. That is a higher rated charging specification, not a guarantee of a particular charging time; the cited pages do not establish a directly comparable real-world charging test.
Processor and cameras: what the specifications can tell you
Different processor families, no verified winner
The Y400 uses Qualcomm’s Snapdragon 4 Gen 2, while the S2 uses MediaTek’s Dimensity 7360-Turbo. They belong to different processor families, and their names alone do not establish which phone performs better. Although the comparison listing includes benchmark scores, its available methodology is not sufficient to treat them as independently verified results. Choose based on a reliable test of the exact models and your own app or gaming needs, rather than assuming a winner from the spec names.

- Includes a high-definition 9H screen protector made from 9H-hardness tempered glass, which effectively resists everyday scuffs, key scratches and accidental knocks, keeping your screen looking as good as new for years to come
- Military-grade drop protection: a hard PC back panel and soft TPU frame combined with shock-absorbing air cushions, plus raised edges to protect the screen and camera lens, providing robust defence against drops, knocks and everyday wear and tear.
- Smooth sliding, secure latching: Precision runners + anti-loosening latches ensure smooth, jam-free sliding and a secure, spring-loaded lock that won’t pop open, making them durable and long-lasting.
- Precise cut-outs, slim and non-slip: Full-featured, precise cut-outs that do not interfere with charging or photography; slim with a textured finish for a non-slip grip, portable and not bulky.
- Innovative 2-in-1 sliding cover and stand: the sliding lens cover doubles as a sturdy folding stand; slide it open to protect against scratches and dust, and close it to instantly transform it into a viewing stand, leaving your hands free for binge-watching or video calls
Similar camera counts, but no image-quality verdict
Both phones list a 50 MP rear main camera and a 32 MP front camera. The S2 page identifies its main sensor as Sony IMX852 and lists a 2 MP bokeh camera; the Y400 lists a 2 MP secondary rear camera. Megapixel counts and sensor naming do not establish which phone takes better photos, and the available specifications are not a substitute for comparable camera testing.
Recommended Free Tools
IP68 and IP69 do not make either phone waterproof
vivo lists IP68 and IP69 ratings for both models, subject to its limitations. On the S2 product page, vivo warns that “The resistance to water is not permanent” and says not to immerse the phone during daily use. The page also states that liquid damage is not covered by warranty. Treat the ratings as limited resistance claims, not permission to use either phone underwater or as a promise of protection after wear or damage. vivo India S2 product page and water-resistance warning
Best Value
- Compatible with Vivo Y400 5G
- Robust, fashion case for pretecting your cell phone against scratches, drops, bumps, shock and scratching.
- Slim, form fitting bumper case design with defined edges and smooth finish. Slides easily in and out of pockets.
- Material: Made of PU leather to offer full protection all around the device.

Which phone should you choose?
- Choose the S2 for its published specifications if you value a larger, sharper display, higher stated battery capacity or vivo’s stated OS and security update commitment—and its final price for your chosen variant works for you.
- Choose the Y400 for its published specifications if 90 W charging matters more to you than the S2’s larger display and battery, or if the Y400’s verified price for the configuration you want is lower.
- Do not choose on an assumed performance or camera winner. The listed processor and camera specifications do not establish which model performs better or produces better images in real use.
Before paying, compare the same storage configuration where available, confirm seller and stock, and use the checkout price rather than the 2026 retailer snapshot as your decision figure.
