Vivo just dropped the Y400 in Pakistan on September 2, like they said they would. This phone packs some solid stuff for the price, especially if you want something tough that lasts all day without dying on you. It comes in one setup—8GB RAM with 256GB storage—and two colors: Dynamic Green and Pearl White. What stands out right away is the huge 6000mAh battery and the IP68 plus IP69 ratings that make it ready for water without freaking out. They even built in underwater photography mode, so you can snap pics while swimming or whatever, as long as you follow the rules. I’ll break it down section by section with more details pulled from the official specs, fixing a few bits from the original info, and adding extras like how it stacks up in real use or tips for getting the most out of it.
Launch and What’s in the Box
The phone hit stores right after the tease, and you can grab it now for Rs 64,999. That’s for the only option: 8GB RAM (which you can bump to 16GB with software extension) and 256GB storage. No other variants yet. Inside the box, you get the usual—a quick guide, USB cable, 44W charger, SIM eject tool, a clear case, screen protector already stuck on, and warranty card. Vivo throws in a 1-year warranty on the phone, 15 days to swap it if something’s off, and 6 months on the accessories. If you pop a Zong SIM in the main slot, you score 2GB free data each month for half a year. Pretty sweet deal if you’re on that network. From what people are saying online right after launch, pre-orders are going smooth, and folks like the bundle since it saves you buying extras right away.
Design and Build Quality
This thing is built like a tank but doesn’t feel heavy. It weighs around 196g to 198g depending on the color, and measures about 162mm tall, 75mm wide, and under 8mm thick—slim enough to slip in your pocket without bulk. The back is a plastic sheet that looks clean in those green or white shades, with a flat frame that gives it a modern vibe. Now, the durability is where it shines: IP68 means it’s dust-proof and can handle being underwater up to 2 meters for 30 minutes (official test says that, though the early buzz mentioned 1.5m—stick to 2m max). IP69 adds protection from high-pressure hot water jets up to 80°C, so rinsing it off or accidental spills won’t kill it. It’s got 3-star military-grade drop resistance too, tested to survive falls without cracking easy. SGS ran checks showing it stays smooth for up to 50 months, which is over 4 years of no lag or glitches if you treat it right. One extra tip: If you use the underwater mode, dry it off proper—wipe ports, let it air out for hours before charging, or you void the warranty on water damage. That’s from Vivo’s guidelines, and it makes sense to avoid headaches.


Performance and Hardware
Under the hood, it’s running a Snapdragon 685 chip on a 6nm process—yeah, it’s from a couple years back, but it handles daily stuff like browsing, apps, and light multitasking without hiccups. You’ve got eight cores clocked up to 2.8GHz on the fast ones, and the Adreno 610 GPU does okay for casual games, but don’t expect it to crush heavy titles like PUBG on max settings without dropping frames. If you’re coming from an older phone, it’ll feel zippy, especially with the RAM extension turning 8GB into 16GB for more apps open at once. Storage is UFS 2.2, so loading things is quick enough. No 5G here—it’s 4G only, with bands that cover Pakistan’s networks fine (like FDD-LTE B1/B3/B5 and so on). Connectivity includes Wi-Fi on both 2.4 and 5GHz, Bluetooth 5.0, USB-C, and GPS support for maps. No NFC or FM radio, though, so if you need those, look elsewhere. Overall, it’s average power for the price, but reliable for work or school without overpromising.
Battery and Charging
Battery life is a big win here. The 6000mAh BlueVolt pack (it’s a lithium-ion with silicon-carbon tech) keeps it going for days on light use—think calls, texts, some scrolling. Even with heavier stuff like videos or GPS, you’ll get through a full day easy. It has 40,000mm² of cooling on the back to stop overheating during charges or gaming. Charging is 44W fast, filling it up quick from zero—about an hour or so to full. Vivo says it can handle up to 90W with their charger, but stick to the included 44W for safety. Compared to other phones around 65k, this battery edges out a lot, especially if you’re outdoors or forget to plug in often. Pro tip: Turn on the battery saver modes in settings for even longer runtime, and avoid extreme heat to keep the cell healthy long-term.
Display Quality
The screen is a 6.67-inch AMOLED that’s flat and bezel-less, with FHD+ resolution (2400×1080) for sharp pics and text. It refreshes at 120Hz, so scrolling feels buttery smooth, and peaks at 1800 nits brightness—great for outdoor use under bright sun without squinting. Colors pop with full DCI-P3 coverage, making movies or photos look vibrant. Touch works even when wet, thanks to the Wet-hand tech that guesses your inputs right in rain or after a swim. Pixel density is 394 PPI, so no fuzzy edges. If you watch a lot of content, this is better than LCD screens on cheaper phones. One addition: It has an in-display fingerprint scanner that’s fast and accurate, plus face unlock for quick access.


Camera and Photography Features
Cameras are straightforward but get the job done. Back has a 50MP Sony IMX852 main sensor (f/1.8 for good low-light) paired with a 2MP depth helper for portraits with blurry backgrounds. It shoots 1080p video at 30fps, and modes include night shots, panoramas, slow-mo, time-lapse, and that underwater photography—perfect for pool pics without a case, as long as you’re not too deep. Front is an 8MP selfie cam (f/2.05) that’s basic but fine for calls or quick snaps. Software adds AI tricks to tweak photos, like boosting colors or fixing faces. From early camera tests online, it handles everyday stuff well, but don’t expect pro-level zoom or 4K video. Extra best here: The dual view mode lets you shoot front and back at once, fun for vlogs, and live photos add a bit of motion like on iPhones.




Software and Extra Features
It ships with Android 15 under Funtouch OS 15, which is clean and packed with tools. AI features help with photo edits, like removing backgrounds or enhancing details without extra apps. You get sensors for everything—accelerometer, gyro, proximity, light—for auto-brightness and gaming. Audio supports common formats, and video playback is smooth on that screen. No hi-fi audio chip, but the speaker is loud enough for calls. If you’re into customization, Funtouch lets you tweak themes and gestures easy. Vivo promises updates, but check their track record—usually a couple years of security patches.
Price, Value, and Final Thoughts
At Rs 64,999, this is a solid pick if you want durability and battery over raw speed. It beats out some competitors like similar Samsung or Infinix models in water resistance and battery size, but lags in gaming power. If you’re clumsy or outdoorsy, the IP ratings and tough build make it worth it—plus the underwater cam is a fun gimmick that actually works. Early posts from users in Pakistan are positive on the battery and screen, though some wish for 5G. If it fits your budget, grab it; otherwise, wait for sales. Messed up buying the wrong phone before? Happens—double-check specs like this to avoid it. Share if you want comparisons to other options.
