Vivo Y400

The Vivo Y400 launched in Pakistan in the second half of 2025. It is a mid-range phone that leads with two things most rivals at its price cannot match: serious water resistance and a huge, long-lasting battery. Where most phones in this bracket stop at a splash-proof rating, the Y400 carries a full IP68/IP69 certification and even includes an underwater camera mode.

It is sold brand-new and box-packed through official Vivo dealers, PTA approved with a one-year official warranty.

Price in Pakistan

Retail listings for this model range from around Rs. 64,999 to Rs. 71,999 depending on the seller and any ongoing promotion, so it is well worth comparing two or three stores before buying.

First, Know Which Y400 You Are Buying

Vivo sells three similarly named phones, and mixing them up is easy. This article covers the standard Vivo Y400 (4G), which uses a Snapdragon 685 chip and UFS 2.2 storage. There is also a Y400 5G, built on a Snapdragon 4 Gen 2 with 5G and faster UFS 3.1 storage, and a pricier Y400 Pro. If 5G or faster storage matters to you, confirm with the seller exactly which model you are being sold, and check the chipset in Settings after switching the phone on.

The Standout Feature: Water Resistance

This is what sets the Y400 apart in its price range. Its IP68/IP69 rating means it is not just splash-resistant — it can survive full immersion and even withstand high-pressure water jets. Vivo pairs this with an underwater camera mode that lets you take photos down to roughly 2 meters without a case.

For Pakistani buyers this is genuinely useful, not just marketing. It means the phone shrugs off monsoon rain, accidental drops in water, and dusty conditions that would kill a normally-rated phone. A couple of honest caveats: Vivo advises keeping underwater sessions to around 30 minutes and drying the phone thoroughly afterwards, and water damage is typically not covered under warranty, so treat the underwater mode as a safety margin rather than something to use daily.

Battery: Built for Load-Shedding

The other headline is the 6,000mAh battery, which is larger than the 5,000mAh cells most rivals use. In practice it delivers up to two days of moderate use, and comfortably a full day even for heavy users. In a country where power cuts are routine, that extra capacity is a real advantage.

Charging is 44W wired, filling to around 50% in 30 minutes, and the charger is included in the box. There is also reverse wired charging to top up other devices. There is no wireless charging.

Display

The 6.67-inch AMOLED runs at Full HD+ (1080 x 2400, around 395 PPI) with a 120Hz refresh rate and up to 1,800 nits peak brightness. That brightness figure is high for the price and makes a real difference in direct sunlight, where many mid-rangers wash out. Being AMOLED, blacks are deep and colors are vivid, and the 120Hz refresh keeps everything smooth.

Performance

The Y400 4G runs the Qualcomm Snapdragon 685 with 8GB RAM and 256GB of UFS 2.2 storage. For everyday use — social media, browsing, video, multitasking — it is smooth and reliable, and games like Call of Duty Mobile run well thanks to the pairing with the 120Hz screen. PUBG runs at up to 60FPS on suitable settings.

Two honest notes. The Snapdragon 685 is a dependable everyday chip rather than a gaming powerhouse, so demanding titles at maximum graphics will need settings reduced. And the storage here is UFS 2.2, which is a step behind the UFS 3.1 found on the Y400 5G — app loading and file transfers are slightly slower as a result.

Camera

The rear setup is a 50MP main sensor at f/1.8 with a 2MP depth sensor and a Ring-LED flash. Video records at 1080p at 30fps. The front camera is an 8MP sensor.

In daylight the 50MP main sensor takes clear, detailed photos with good color. The 2MP depth sensor only assists with portrait blur and is not a lens you will use on its own. This is a capable point-and-shoot camera for social media rather than a photography standout, and low-light results are average for the price. The distinctive Ring-LED flash around the camera does add a nice touch for fill light in selfies and close-ups.

Software

It runs Android 15 with Funtouch OS 15. Reviewers describe Funtouch as relatively light on bloatware compared to some rivals, with useful additions like an always-on display, a theme store, app cloning for dual WhatsApp, and Circle to Search. Vivo has committed to two years of OS updates, which is reasonable for this segment though not class-leading.

Build and Connectivity

At 7.9mm and around 196g, the Y400 has a flat-frame unibody design with a glass front and plastic back that looks clean and modern. The fingerprint sensor sits under the display. Connectivity is 4G LTE only on this model — there is no 5G and no NFC, which are the two most notable omissions. You do get dual-band Wi-Fi, Bluetooth 5.0, USB-C with OTG, and Hi-Res audio support. There is no microSD card slot, so the 256GB is all you get.

• Only a 2MP depth sensor as a secondary camera, no ultrawide
• Average low-light photography
• No microSD card slot
• Water damage is not covered by warranty
• No wireless charging

Reviews

Two features dominate the positive feedback: the battery and the water resistance. Owners repeatedly mention getting close to two days of use, which resonates strongly given routine load-shedding, and the IP68/IP69 rating is seen as genuine peace of mind rather than a gimmick. The bright AMOLED screen and the clean Fun touch software also earn praise.

The criticism centres on what is missing rather than what is wrong. The lack of 5G and NFC comes up most, particularly from buyers who want the phone to stay relevant for several years. Some also note that the camera is fine but not a highlight, and that the UFS 2.2 storage is a step behind the 5G version.

The general verdict is that the Y400 is an excellent choice for someone who wants outstanding battery life and rugged water resistance in a good-looking phone, and who does not need 5G or a standout camera. If 5G or faster storage is a priority, the Y400 5G is the better fit despite the higher price.

Things to Check Before Buying

Confirm the exact model

Make sure you are getting the Y400 4G and not the 5G or Pro if that is what you intend, and check the chipset in Settings after switching the phone on. The three share a name but differ in chip, storage speed, and connectivity.

Inspect the box seal

A factory seal is crisp, tight, and evenly printed. Cut or re-taped seals, dented corners, or blurry printing on the box are signs it has been opened or that the box is a duplicate.

Check the phone as soon as the box opens

A factory-applied screen protector has clean edges and no bubbles. Look at the screen corners and back panel for micro-scratches, and peel back the wrapping film to check underneath.

Test the AMOLED panel

Open a plain white image and a plain black one to check for uneven patches or dead pixels, and confirm the refresh rate is set to 120Hz in Settings.

Verify the IMEI

Dial *#06# and confirm on PTA's DIRBS portal or by sending the IMEI to 8484. The number on the box, the sticker, and the phone must all match.

Confirm accessories and warranty

The 44W charger, cable, and SIM pin should all be in the box. The warranty card needs a proper seller stamp and a clear date, and remember that water damage is generally excluded from the warranty despite the IP rating.

Resale Value

As a recent 2025 model, the Y400 has not depreciated much yet, but Vivo mid-rangers do lose value steadily. Based on current market trends, a unit in good condition can be expected to fetch roughly Rs. 48,000 to 56,000 after about a year.

Condition drives most of that. Scratches, dents, or screen damage pull it down sharply, and a weak battery is an instant red flag for buyers. Keeping the original box, 44W charger, and invoice noticeably raises what you can ask.

The strong battery and water resistance help this phone appeal to used buyers, but the missing 5G will weigh on resale over time as 5G becomes standard in this price range in Pakistan. If you plan to upgrade, sooner holds more value than later.

Alternatives Worth Considering

• Vivo Y400 5G — the same family with 5G, a faster chip, and quicker UFS 3.1 storage, for a higher price. The pick if future-proofing matters.
• Redmi Note 14 — a strong rival with a more capable camera system and competitive pricing.
• Infinix Note 40 — worth comparing for charging speed and features in the same bracket.
• Samsung Galaxy A26 — costs a little more but adds 5G, NFC, and Samsung's longer software support.
