Summary
- The Allview V4 Viper Pro features a larger 6.8-inch IPS LCD display with a resolution of 640 x 1352 pixels, while the vivo Y81i has a 6.22-inch IPS LCD with a higher resolution of 720 x 1520 pixels, resulting in better pixel density and clarity.
- In terms of performance, the V4 Viper Pro is powered by a Mediatek MT6739 chipset with a 1.3 GHz quad-core CPU, whereas the Y81i utilizes a more efficient Mediatek MT6761 Helio A22 with a 2.0 GHz quad-core CPU, offering superior processing power.
- Both devices have a 13 MP rear camera capable of 1080p video recording, but the Y81i's camera benefits from PDAF for faster focusing.
- The V4 Viper Pro has a slightly larger 3500 mAh battery compared to the Y81i's 3260 mAh, but both lack fast charging.
- In terms of software, the V4 Viper Pro runs Android 9.0 (Pie), while the Y81i operates on an older Android 8.1 (Oreo) with Funtouch 4, which may affect user experience and app compatibility.
- Build quality favors the Y81i with Gorilla Glass on the front, making it more durable, while the V4 Viper Pro is heavier and bulkier.
