The vivo Y31d was unveiled quietly – while it is similar to the Y31 and Y31 Pro, it has a couple of key differences. The main one is the 4G-only chipset, a Snapdragon 6s 4G Gen 2. The other important difference is the larger 7,200mAh battery (the other two have decently-sized 6,500mAh batteries).
The Y31d comes in Glow White and Starlight Gray. It measures 166.6 x 78.4 x 8.39mm (8.49mm for the White color) and weighs 219g. The phone is rated “IP69+”, which promises protection against splashes, rain, high-pressure water jets and submersion in up to 1.5m of water for up to 30 minutes.

Despite its relatively slender build, the vivo Y31d houses a 7,200mAh BlueVolt battery. That’s enough for over 13 hours of MOBA gaming, over 14 hours of navigation or almost two days straight of video playback (45 hours).
The 44W FlashCharge system promises 1% to 50% charge in 43 minutes. And there’s a Bypass Charging option, if you want to game on external power. The battery is rated for 6 years of use.
The body of the vivo Y31d is made out of a plastic composite, but the camera island is made of metal. Said camera has a 50MP main module (f/2.0 lens) with a 2MP helper on the back and there is an 8MP (f/2.0) selfie camera on the front.
The front is home to a 6.75” LCD with 720 x 1,570px resolution. It’s a 120Hz panel that can reach 1,250 nits of brightness. The fingerprint reader is mounted on the side.
The phone has dual nano-SIM slots and, again, is a 4G-only handset. It also supports dual-band Wi-Fi, Bluetooth 5.1 and has a USB 2.0 port. There’s no NFC on board. There’s no headphone jack either, but at least the phone has stereo speakers (with 400% volume boost).
The Snapdragon 6s 4G Gen 2 is paired with 6GB/8GB of RAM (LPDDR4X) and 128GB or 256GB storage (UFS 2.2). It will run Android 16 / OriginOS 6 out of the box.
We don’t have pricing details just yet, but the vivo Y31d can be found in Cambodia and Vietnam at the official vivo sites for those countries.
