Vivo Y400 Pro 5G

Name: Vivo Y400 Pro 5G
Brand: Vivo
SKU: 8312

Manufacturer: Vivo

The Vivo Y400 Pro 5G is a mid-range 5G smartphone built around a 6.77″ OLED panel that runs at a 120Hz refresh rate with a peak brightness of 1300 nits and Always-On Display support. It carries an IP65 rating for dust and water resistance, sits at a slim 7.7 mm thickness, and weighs 182 g, giving it a relatively compact physical profile despite its large screen.

Under the hood, the device runs on a MediaTek Dimensity 7300 chipset built on a 4 nm process, paired with 8 GB of LPDDR5 RAM clocked at 6400 MHz and 256 GB of internal storage. The main camera system combines a 50 MP and a 2 MP sensor, while a 32 MP front camera handles selfies. A 5500 mAh battery with 90W wired fast charging rounds out the hardware, and the phone ships with Android 15, NFC, Bluetooth 5.4, and dual-SIM 5G connectivity.

Pros

The 5500 mAh battery paired with 90W wired fast charging means the device can be topped up quickly despite its large capacity
An IP65 rating provides genuine protection against dust and water in everyday situations
The 6.77-inch OLED display reaches 1300 nits of brightness and supports HDR10 and Always-On Display, making it usable in varied lighting conditions
At 7.7 mm thick and 182 g, the phone keeps a slim and manageable physical profile for its screen size
Stereo speakers are present, offering a more immersive audio experience compared to a single-speaker setup
5G connectivity with NFC, Bluetooth 5.4, and Galileo satellite support makes it a well-connected daily device

Cons

No wireless charging is supported, limiting charging flexibility
The 3.5 mm headphone jack is absent, requiring an adapter or wireless headphones for wired audio
None of the advanced Bluetooth audio codecs — including aptX, aptX HD, LDAC, or aptX Adaptive — are available, restricting high-quality wireless audio output
The rear camera lacks optical image stabilization and a back-illuminated sensor, which can affect photo quality in low light or during movement
USB connectivity is limited to USB 2.0 speeds despite the Type-C port, slowing down wired data transfers
Direct OS updates from the vendor are not provided, which may affect the timeliness of future software support

Who is this for?

This phone suits everyday users who want a large, vivid screen for media consumption, thanks to its 6.77-inch OLED display with 120Hz refresh rate and 1300-nit brightness with HDR10 support. The 5500 mAh battery and 90W fast charging make it a solid fit for people who need reliable all-day power without long waits at the charger, while the IP65 rating and slim 7.7 mm build appeal to those who want practical durability in a non-bulky form. Users who prioritize 5G connectivity, NFC for contactless use, and a capable dual-camera setup with broad manual controls and 4K video recording will also find it well-suited to their needs.

Who is this NOT for?

Users who depend on wired headphones via a 3.5 mm jack or require high-fidelity wireless audio through codecs like LDAC or aptX will find the audio options limiting. Mobile photographers who need optical image stabilization or RAW shooting for serious still work will be constrained by the rear camera system, and the absence of a back-illuminated sensor may affect low-light results. Power users who rely on fast file transfers will be held back by the USB 2.0 interface, and those who expect timely long-term software support may be deterred by the lack of direct OS updates from the vendor.
