The Vivo Y31d arrives as a big-battery mid-ranger that tries to look and feel more premium than its price suggests, and that starts the moment you lift the lid on the box. Instead of chasing ultra-slim minimalism, Vivo leans into practicality, bundling the essentials you actually need to start using the phone at full speed from day one. In my unboxing, the combination of a huge battery, fast charger, and protective extras immediately framed the Y31d as a device built for long, hard daily use rather than short spec-sheet wins.
That first impression matters because the Y31d is launching into a crowded field of budget and mid-range Android phones that often cut corners on accessories and durability. Here, the hardware story begins with a 6.75-inch display and a 7,200mAh battery, but the way Vivo packages and presents those components hints at a broader strategy: make this phone feel like a complete kit, not just a bare device.
Box contents and first look
Opening the retail package, I find a surprisingly complete set of accessories compared with many rivals that now ship without chargers. The official Box Contents list includes the Phone, a 44W Charger, a Type-C Cable, a SIM Ejector Tool, and a Case, which means most buyers will not need to spend extra on basics. That 44W brick is particularly important given the size of the battery inside, and the bundled case immediately takes the edge off any anxiety about scratching the back panel in the first few days.
The phone itself sits on top, wrapped in a thin protective film that highlights key specs like the 7,200mAh battery and the large 6.75-inch LED display. Underneath, the charger and cable are arranged in simple cardboard compartments, with the SIM tool and case tucked into a slim envelope. It is a straightforward, no-nonsense presentation, but the inclusion of every essential accessory gives the Y31d a more generous feel than many stripped-back competitors that ship with only a cable in the box.
Design, colors, and in-hand feel
Once out of the plastic, the Y31d’s design language leans clean and functional rather than flashy, but the color options help it stand out. Buyers can choose between a bright Glow White finish and a more understated Starlight Gray, both of which aim to disguise fingerprints better than glossy black glass. In hand, the phone feels substantial but not unwieldy, with the large battery adding a bit of heft that actually helps it sit securely in the palm. The camera island is neatly integrated, avoiding the oversized, wobbly modules that plague some budget designs.
Vivo’s broader design language is visible if you compare the Y31d with earlier models such as the Y31, which lists its Body Dimensions at 163.86 by 75.32 by 8.38mm. The Y31d follows a similar template of rounded corners, a flat display, and a slightly curved back that tapers into the frame, making the large screen easier to grip. Button placement is conventional, with the power and volume keys on the right and the SIM tray accessible via the included ejector tool, so there are no surprises as you start setting it up.
Display and everyday usability
The centerpiece of the front is the 6.75-inch LED panel, which immediately dominates your field of view when you power on the phone. According to the Full Specifications, this screen size is paired with support for 1080p at 30fps video playback, which is a sensible match for streaming and social media. In daily use, that combination should translate into crisp-enough text and video without pushing the chipset or battery too hard, a balance that matters more in this price band than chasing ultra-high refresh rates at the expense of endurance.
Brightness and smoothness are tuned for mainstream use rather than flagship-level punch, but the panel is still designed to handle outdoor visibility and scrolling-heavy apps. Reporting on the Y31d notes that the display can reach up to 120Hz and a peak brightness of up to 1,250 nits, with those details tied to The Vivo Y31d’s broader spec sheet. In practice, that means swiping through Instagram, watching YouTube, or reading long articles should feel fluid, while the high brightness ceiling helps the phone stay legible in direct sunlight or under harsh indoor lighting.
Battery, charging, and durability
The most striking spec inside the Y31d is its massive 7,200mAh battery, which immediately sets expectations for multi-day stamina. That capacity is paired with 44W FlashCharge support, and the charging system is rated to take the battery from 1% to 50% in 43 m, a figure highlighted in early Vivo coverage. In real-world terms, that means a quick top-up over breakfast or during a short break can easily add enough power for a full workday, which is crucial when you are dealing with such a large cell.
Durability is another pillar of the Y31d’s pitch, with the phone carrying an IP69+ rating that signals resistance to dust and high-pressure water jets. That level of protection, combined with the bundled case and the robust battery, positions the device as a practical choice for users who spend a lot of time outdoors or in harsher environments. The unboxing experience reinforces this impression, with the packaging and accessories clearly geared toward people who want a phone that can survive rough handling rather than sit delicately on a desk.
Performance, software, and cameras
Under the hood, the Y31d is powered by the Snapdragon 6s 4G Gen 2 chipset, which makes it a 4G-only smartphone but still gives it enough muscle for everyday tasks. The device runs on Android 16 with OriginOS on top, according to Snapdragon focused reporting, and that combination should deliver a familiar Android experience with Vivo’s own customization layer. From the first boot, setup is straightforward, with Google services and Vivo’s utilities coexisting, and the large battery plus efficient chipset promising smooth performance for messaging, browsing, and casual gaming.
On the imaging side, Said camera has a 50MP main module with an f/2.0 lens, backed by a 2MP helper on the rear and an 8MP f/2.0 selfie camera on the front, as detailed in early camera breakdowns. That setup is not trying to compete with flagship multi-lens arrays, but it does aim to cover the basics: sharp daylight shots from the main sensor, serviceable portraits with the depth helper, and social-ready selfies. During unboxing, the camera app loads quickly, with standard modes like photo, video, portrait, and night easily accessible from the bottom carousel.
