Vivo Y31d review
The Y31d is for buyers who prioritize durability and battery longevity over performance or screen clarity—outdoor workers, frequent travelers, or anyone who hates phones that die by dinner. Skip it if you expect smooth multitasking, rich graphics, or crisp text; the 720p screen and budget chipset will disappoint anyone used to a modern mid-range phone.
This review is written with AI assistance from Vivo’s published specifications and public benchmark data for the Vivo Y31d, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The Vivo Y31d is a compact budget phone with IP68 durability, a bright 120Hz display, and a 7200 mAh battery that should deliver two solid days of use. For its price, it offers good everyday resilience and longevity, but the 720p resolution and budget chipset mean don't expect smooth performance in demanding apps.
Design & build
The Y31d is slim and grippable—at 8.4mm thick and 219g, it feels light in hand, which is rare enough at this price. The glass front and plastic back are standard fare, neither premium nor flimsy. The real story is IP68/IP69 water and dust resistance that survives dust-tight sealing and high-pressure jets at 1.5 meters for 30 minutes. Most competitors at this price skip full water resistance or offer only IP54; this level of durability is a tangible advantage if you work outdoors, travel by bike, or just live somewhere wet. Dual nano-SIM and a side-mounted fingerprint sensor round out the basics—no surprises, but no corners cut either.
Display
The 6.75-inch IPS screen is bright at 1250 nits peak brightness and runs at 120Hz, both welcome for daylight visibility and scrolling fluidity. But the 720p resolution (256 ppi) is the catch. On a screen this large, pixels start to show; text looks softer than a 1080p rival, and fine graphics are noticeably grainier. By early 2026, most budget phones have adopted 1080p as the floor, so this feels a step behind. That said, 85.3% screen-to-body ratio is solid, and for basic browsing and video, the brightness advantage and refresh rate mask the resolution shortfall better than you'd expect.
Performance
The Snapdragon 6s Gen 2 is entry-level processing power. It will handle text, social media, and light gaming without hiccup. Heavier apps—file managers, video editors, demanding games—will lag or stutter. RAM options up to 8GB don't compensate for a weak chipset; memory alone doesn't make a slow processor fast. For everyday messaging and scrolling, it suffices. For anything more ambitious, you'll notice the gap against even mid-range rivals. UFS 2.2 storage is slow by modern standards, so app launches and file transfers will feel sluggish compared to faster interfaces.
Software
Android 16 with OriginOS 6 is current and means the phone will receive system updates for a reasonable window. OriginOS is Vivo's skin, usually light and responsive, though it adds a layer of customization that some users love and others find intrusive. No mention of major slowdowns or bloat in typical reviews of the Y-series, so the software experience should be straightforward and close to stock-ish for a Vivo product.
Camera
The 50MP main camera with f/2.0 and PDAF is capable in bright light, and the 21mm focal length (standard wide angle) keeps framing familiar. But megapixel count alone misleads—50MP through a modest sensor and modest processing will produce sharp detail in good light and muddy results in shadow or evening. The 8MP selfie and 1080p video from both cameras are baseline for this tier. Night mode performance and low-light clarity will likely disappoint compared to rivals with larger sensors or better image processing. This is a daytime camera.
Battery & charging
The 7200 mAh battery is a genuine strength at this price. Paired with an efficient entry-level chipset, two full days is realistic with moderate use, a real advantage over typical 5000–6000 mAh rivals that die by evening. The critical gap: no charging wattage is specified in the official specs, a strong hint that the charger is slow (likely 18–33W). This undermines the battery win—you may have a two-day phone, but refilling it takes hours, which defeats the point of a large battery. Until confirmed otherwise, assume slow charging and plan accordingly.
Value & verdict-context
At around 170 EUR, the Y31d competes in a crowded entry-level bracket. The IP68 durability, bright display, and large battery are genuine draws for buyers who value resilience and longevity over performance. The 720p screen and weak chipset will frustrate anyone expecting smooth app performance or image quality beyond daylight. For someone who wants a tough, pocketable phone that lasts days and costs little, this hits. For anyone hoping for a smartphone that also plays games or runs heavy apps without lag, look elsewhere. The lack of a specified charge speed is the shadow here—if the charger is indeed slow, the battery advantage evaporates into a long wait at the outlet every two days.
Verdict
The Y31d is for buyers who prioritize durability and battery longevity over performance or screen clarity—outdoor workers, frequent travelers, or anyone who hates phones that die by dinner. Skip it if you expect smooth multitasking, rich graphics, or crisp text; the 720p screen and budget chipset will disappoint anyone used to a modern mid-range phone.
- IP68/IP69 rating at this price tier—most rivals skip full water and dust resistance, making this genuinely durable for rough handling and accidental splashes
- 7200 mAh battery with efficient hardware should stretch to two days on a single charge, a real advantage over typical 5000 mAh budget phones
- 120Hz IPS display with 1250 nits peak brightness is bright enough for outdoor use even in sunlight, and the refresh rate helps scrolling feel smooth relative to the chipset's power
- Compact at 8.4mm thin and 219g—slim and light enough to slip into a pocket without bulk, which matters for users who don't want a phone shaped like a brick
- 720p display on a 6.75-inch screen means text and fine detail look softer than a 1080p rival at the same size; most budget phones have stepped up to 1080p by now
- Snapdragon 6s Gen 2 is entry-level and will stutter in heavy apps or games—this is bottom-tier processing power, adequate for messaging and social media but not much else
- No charging wattage listed in the specs, a red flag suggesting slow charging that will drag out your two-day battery advantage
