The Vivo Y400 5G has entered the mid-range market as a feature-rich smartphone designed for everyday users who want style, stamina and speed without paying flagship prices.
Design and Display
This phone carries a slim yet solid design with curved edges and attractive colour options. On the front sits a large 6.67-inch AMOLED display with Full-HD+ resolution and a fast 120 Hz refresh rate. The high brightness makes it easy to read outdoors, while vivid colours enhance streaming and gaming.

Performance
Under the hood is Qualcomm’s Snapdragon 4 Gen 2 processor, paired with 8 GB of RAM and 128 GB or 256 GB of internal storage. It’s tuned for smooth day-to-day performance, multitasking and casual gaming. Users can also enable virtual RAM expansion for heavier apps.
Battery and Charging
One of the standout features is its huge 6,000 mAh battery. Combined with 90 W fast charging, it can easily last a full day of heavy use and still recharge quickly when needed. This makes it ideal for travellers, students or professionals on the go.
Cameras
On the back, the Y400 5G offers a 50-megapixel main camera plus a depth sensor for portrait shots. On the front, a high-resolution 32-megapixel camera handles selfies and video calls. The camera app includes night mode, portrait mode and underwater photography mode for creative shots.
Durability
The phone is rated IP68 and IP69 for dust and water resistance — a rare perk in this price segment. This extra durability gives peace of mind for outdoor use and accidental splashes.
Software
It runs the latest Android version with Vivo’s Funtouch OS interface, offering a fresh look, customisation options and privacy controls. Pre-installed apps can be removed or hidden if desired.
