The vivo S2 5G has a larger, higher-resolution display and a higher-capacity battery on paper; the vivo Y400 5G charges faster. In a 2026 91mobiles retailer-page snapshot, the S2 was listed ₹4,901 above the Y400, but prices and stock vary by seller and configuration. The S2 discussed here is the newer India-listed model with a Dimensity 7360-Turbo chip, a 7,050 mAh battery and a 6.83-inch display—not an older phone that may share the S2 name.

Which phone has the better display?
On the published specifications, the S2 has the larger and higher-resolution screen: 6.83 inches at 1.5K, compared with the Y400’s 6.67-inch FHD+ display. Both advertise refresh rates of up to 120 Hz. The listed figures establish a resolution and size difference, but do not by themselves establish which screen looks better in person.
Battery capacity or faster charging?
The S2 lists a typical 7,050 mAh battery, compared with 6,000 mAh for the Y400. The Y400, however, lists 90 W FlashCharge, while the S2 lists 44 W charging. Capacity alone does not prove longer real-world battery life, and these manufacturer specifications do not establish comparative endurance or charging times under particular conditions.

How do their processors compare?
The Y400 uses Qualcomm’s Snapdragon 4 Gen 2; the S2 uses MediaTek’s Dimensity 7360-Turbo. They belong to different product families, and the chip names alone are not a reliable basis for declaring a performance winner. A comparison page reports benchmark scores, but its available test methodology is insufficient to treat those figures as independently verified results. No independent testing establishes which phone performs better in everyday use.
What do the camera specifications tell you?
Both phones list a 50 MP main rear camera and a 32 MP front camera. The S2 identifies its main sensor as a Sony IMX852 and also specifies a 2 MP bokeh camera; the Y400 lists a 2 MP secondary rear camera. Megapixel counts and sensor names do not establish image quality, so the specifications alone cannot show which phone takes better photos.

Are the phones waterproof?
vivo lists IP68 and IP69 ratings for both phones, subject to its stated limitations. On its official S2 product page, vivo says, “The resistance to water is not permanent,” and warns users not to immerse the phone during daily use. vivo also says liquid damage is not covered by warranty. Treat the ratings as limited resistance claims, not as permission to use either phone as a professional waterproof device.

Which should you choose?
- Consider the S2 if its listed larger, higher-resolution display or higher battery capacity is more important to you, and its price and availability work for your preferred configuration.
- Consider the Y400 if you value its listed faster 90 W charging or find it at a lower current price for the storage variant you want.
- Compare the exact listings before deciding: the observed ₹4,901 difference is a retailer snapshot, not a guaranteed saving or a like-for-like price for every configuration.
- Do not choose on unverified assumptions about battery life, camera quality or processor performance; the published specifications do not settle those real-world comparisons.
