The Vivo Y400 5G has a big 6000mAh battery, an IP69 waterproof rating, and a bright AMOLED screen, but the Snapdragon 4 Gen 2 chip might not let it do very much.
The Vivo Y400 5G is here, and at first glance, it looks great. It has a flat AMOLED screen, a big battery, a waterproof rating, and it charges very quickly. But when you look more closely, the real question is whether this phone is worth the ₹22,000 price tag.

This device might not meet your wants, and your money should be spent on something better. Let’s break it all down.
What Is Vivo Y400 5G All About?
Vivo’s newest effort to break into the Indian mid-range smartphone market is the Y400 5G. It puts a lot of emphasis on a flat-screen experience, which is good for people who don’t like how curved screens work. Vivo wants to combine everyday usability with current design with its strong build quality, super-bright screen, and the latest version of Android.
Launch date: August 4, 2025
Expected Price: ₹22,000 (can dip to ₹20,000 with offers)
Key Features: What’s Inside
Here’s a quick rundown of the tech inside the Vivo Y400 5G:
- Display
A 6.67-inch Full HD+ AMOLED screen with a 120Hz refresh rate
Flat, no curves, and reaches up to 1800 nits brightness — easy to view even outdoors - Cameras
50MP rear shooter with a Sony IMX852 sensor and OIS (optical stabilization)
32MP punch-hole selfie camera
Secondary rear camera is 2MP — mostly for design symmetry, not function - Battery and Charging
6000 mAh battery — easily lasts a day and a half with regular use
90W fast charging through USB Type-C — claimed to power up in under 40 minutes - Chipset
Qualcomm Snapdragon 4 Gen 2 — decent for daily use, but not ideal for gaming or power users
Backed by LPDDR4X RAM and UFS 2.2 storage - Build and Extras
IP69 rating for full waterproof and dustproof durability
In-display fingerprint scanner
Dual stereo speakers, but no 3.5mm headphone jack - Software
Android 15 out-of-the-box with Vivo’s custom Funtouch OS
Includes AI features like Circle to Search, transcript assist, AI summaries, and more
Where the Y400 5G Shines
- That flat display is rare in this price segment great for content viewing, reading, and no accidental touches
- Battery life is top-tier with 6000 mAh capacity, casual users can go up to two days without charging
- Waterproofing (IP69) is a bold move ideal for those with active lifestyles or clumsy hands
- AI software features are useful for productivity, not just gimmicks
Where It Slips
- Processor is underwhelming
The Snapdragon 4 Gen 2 performs fine for basics, but struggles under load — not ideal for those who multitask, game, or push their phone to the limit - Storage tech is dated
UFS 2.2 is a bit slow for this price range. Apps may load slower compared to phones with UFS 3.x storage - No headphone jack
For wired audio lovers or gamers, this might be a dealbreaker - Short update cycle
Only 2 years of Android updates expected — less than some rivals offering 3–4 years
