The vivo S2 has the larger, sharper display, a higher stated water- and dust-resistance rating, and a larger battery capacity. The vivo Y400 Pro 5G has a documented India store price of ₹31,999 for 8GB+256GB and specifies 90 W charging. An official India price for the S2 was not established, so there is no reliable like-for-like price difference to report.

Which phone has the better display?
The S2 leads on the published display specifications: its curved OLED screen is listed at about 6.83 inches, 1.5K resolution, 120 Hz, and 449 PPI. The Y400 Pro has a 6.77-inch AMOLED panel with 2392 × 1080 resolution and a refresh rate of up to 120 Hz. Both list a 120 Hz maximum refresh rate, but the S2 offers the larger, higher-resolution screen.
Battery capacity versus charging speed
The S2’s stated 7050 mAh battery is larger than the Y400 Pro’s 5500 mAh typical-capacity battery. That difference alone does not establish which phone lasts longer in everyday use: screen settings, signal strength, apps, and other factors affect runtime. For charging, the Y400 Pro has a stated 90 W rating; the reviewed official S2 feature page does not specify a charging wattage.

Performance: two different Dimensity chips
The Y400 Pro uses a 4 nm MediaTek Dimensity 7300, while the S2 uses a 4 nm Dimensity 7360-Turbo. These are distinct processors, but their names and manufacturing-process figures are not enough to establish which phone feels faster in real use. vivo reports an AnTuTu score of 970,000 for the S2 using the 8GB+256GB edition and AnTuTu Benchmark V11, but calls the result reference-only and notes that results vary. Without matching independent tests for both phones, that figure is not a fair head-to-head performance comparison.
Camera specifications
Both phones list a 50 MP main-camera class, a secondary 2 MP rear camera, and a 32 MP front camera. vivo identifies the S2’s main sensor as a Sony IMX852 and describes the secondary camera as a bokeh camera. Similar headline megapixel counts do not demonstrate equal photo or video quality; the published specifications here do not establish a camera-quality winner.

Durability: higher ratings do not mean waterproof
The S2 carries IP68 and IP69 ratings under vivo’s stated laboratory conditions, compared with IP65 for the Y400 Pro. These ratings describe tested resistance, not a guarantee against water damage in every situation. vivo says of the S2, “The resistance to water is not permanent,” and states that liquid damage is excluded from warranty coverage. vivo also says Y400 Pro protection may decrease over time. Neither phone should be described as waterproof. See vivo’s S2 product page and Y400 Pro specifications for the manufacturers’ qualifications.

vivo says the S2 receives three generations of OS updates and five years of security updates. The company measures that period from the product’s launch event in the country or region where it was purchased. The reviewed Y400 Pro specification page does not state a comparable support duration, so these sources do not establish whether its support is shorter or longer. Details are on vivo’s S2 product page.

Price difference in India
vivo’s India store displayed the Y400 Pro 5G 8GB+256GB at ₹31,999 including taxes on 2026-10-04, while marking the selected product unavailable. The reviewed official S2 page did not establish an India price or current retail configuration, so the official pages do not support calculating a price difference.
A 91mobiles comparison page captured on 2026-10-04 showed ₹39,999 at Amazon for the S2 and ₹25,991 for the Y400 Pro, with the latter marked out of stock. These are third-party listing snapshots, not confirmed current offers or a like-for-like comparison; configurations and seller details should be checked on the listing before relying on them.

Which one should you choose?
- Choose the S2 if your priorities are the larger, higher-resolution display, greater stated battery capacity, higher published IP rating, or its stated software-support term.
- Choose the Y400 Pro if you want a documented official India store price for the 8GB+256GB configuration or a specified 90 W charging rate.
- Do not choose on a claimed performance or camera winner based on these specifications alone: the available evidence does not provide a matching independent comparison.
