Display, processor, and storage
The 6.67-inch AMOLED panel has a 2400 × 1080 resolution and supports refresh rates up to 120 Hz. “Up to” matters: the phone may use a lower rate depending on the app or interface, rather than running at 120 Hz at all times. The 1,800-nit figure is vivo’s stated local peak brightness, not a guarantee of that brightness across the entire screen.
The Snapdragon 4 Gen 2 is paired with 8 GB of LPDDR4X RAM and UFS 3.1 storage. vivo also lists up to 8 GB of extended RAM. That feature allocates storage for software use; it is not additional physical RAM. The available capacities are 128 GB and 256 GB.

Battery and charging claims
vivo specifies a 6,000 mAh typical battery capacity and a separate rated capacity of 5,880 mAh. Its India product overview says the phone can reach 50% charge in about 20 minutes, based on vivo laboratory testing starting at 1% battery with its standard charger and cable under specified controlled conditions. Actual charging time varies with temperature, starting charge, cable and adapter, and phone use. The 90 W rating is the maximum supported charging power, not a rate the phone necessarily sustains throughout a charge.

Camera hardware
The rear setup combines a 50 MP main camera, identified by vivo as a Sony IMX852 sensor, with a 2 MP camera. The front camera is 32 MP. These figures describe camera hardware; they do not by themselves establish image quality in different lighting or compared with other phones.
What IP68/IP69 protection means in practice
vivo rates the Y400 5G IP68 and IP69 for dust and water resistance, but those ratings do not mean unrestricted water use. vivo says underwater photography should use fresh water only, at depths up to 2 metres and for no longer than 30 minutes per use. Dry the phone and make sure the USB port is completely dry before connecting a cable or charging. Immersion damage is excluded from the warranty, and resistance can decline with wear.
