Display and 120Hz smoothness

The 6.72-inch panel runs FHD+ at up to 120Hz. It is LCD, not AMOLED, but the 1050 nits HBM spec is decent for bright Indian afternoons. Expect smooth scrolling and better perceived responsiveness at 120Hz, with the usual trade-off of slightly higher battery drain versus 60Hz.

Battery life and 44W charging

A 6500mAh pack is the headline. With mixed use at auto-brightness and adaptive refresh, most users should see a comfortable 1.5 to 2 days. The included 44W adapter shortens top-ups. Battery life depends on 5G time, screen brightness, and app mix, but capacity is clearly the selling point here. Vivo

Cameras and 4K video

You get a 50MP main sensor and a 2MP depth helper, plus an 8MP selfie. There’s no OIS, but 4K video is supported per vivo’s listing. Expect crisp daylight shots from the main camera, basic portraits from the depth assist, and usable selfies in good light.

Design and Build Quality

The Y31 Pro feels practical. The composite back resists fingerprints better than glossy glass, the side fingerprint is quick, and the IP64 rating adds dust protection and light water resistance. The weight touches ~204–208g because of the large battery.

Display and audio

• Panel: LCD, 120Hz, FHD+, 1050 nits HBM
• Audio: Standard loudspeaker setup, USB-C audio; Bluetooth 5.4 covers modern codecs
  LCD’s blacks are not as deep as OLED, but text sharpness at FHD+ is fine, and HBM brightness helps outdoors. If AMOLED is a must, consider rivals below.

Performance and thermals management

The Dimensity 7300 (4nm) focuses on efficiency. For day-to-day tasks—WhatsApp, Chrome with multiple tabs, short video edits, Maps—you should be comfortable. Thermals are generally easier to tame on this class of SoC, which matters in Indian summers. For heavier gaming, keep expectations in check and tune to medium settings for steadier frames.

Everyday responsiveness

With 8GB RAM and UFS 3.1 storage, cold app opens and multitasking are snappy for the segment. Extended RAM helps with background app retention, though it is still using storage swap and should not be treated like physical RAM.

Gaming stability

Casual titles run well. Heavier shooters will run at moderate graphics and frame rates; dropping one notch often delivers a more stable experience without major visual loss on an LCD. Sustained outdoor gaming will still warm the phone; a case helps with comfort.

Benchmark comparisons

We avoid guessing synthetic scores we didn’t run. In this price class, Dimensity 7300 sits ahead of 6100-series chips and trades blows with lower-tier Snapdragon 6-series parts in multi-core workloads. Use this as context, not a lab result.

Camera

You get reliable daylight shots with a natural color profile. The absence of OIS means low-light shots will depend on the Night mode and steady hands. Portraits rely on edge detection and the depth sensor, so subject-background separation may vary with hair and complex edges. Video tops out at 4K on the rear camera; stick to 1080p for steadier results in mixed light.

Battery and charging

• Capacity: 6500mAh
• Charging: 44W, charger included
• Real-world note: Expect 1.5–2 days with 60–120Hz adaptive, auto-brightness, and mixed 5G/Wi-Fi. Heavy camera, navigation, and gaming sessions will shorten it. Include a quick 20–30 minute top-up in the evening and you should still wake up with plenty left.

Software and updates

Shipped with Android 15 and Funtouch OS 15. Vivo does not publish a universal, long-term OS upgrade promise for Y-series on the product page. Historically, mid/budget models have received around 1–2 Android version upgrades and multiple security updates. Treat this as guidance, not a guarantee, and watch for official announcements.

Network and 5G bands

Supported 5G bands: n1, n3, n5, n8, n28B, n40, n77, n78. That covers India’s core bands (including n78 for most carriers). Dual-SIM is supported. For travelers, always check your destination carrier’s band map.

Value for money
If your priorities are battery longevity, smooth UI, and dust/water protection at this budget, the Y31 Pro 5G is easy to recommend. If you value OLED blacks or advanced camera hardware, see the alternatives below.
