Quick decision rule
AI + verified factsChoose Oppo A6 Pro 5G if you want the only verified chipset model listed and are comfortable giving up some battery capacity. Choose Vivo Y51 Pro 5G if the larger 7,200 mAh battery matters most, because both phones are similarly priced and the rest of the comparison lacks enough verified data for a firmer split.
Final verdict
The verified data points to a simple trade-off: Vivo Y51 Pro 5G has the stronger battery case, while Oppo A6 Pro 5G is the only one with a verified chipset model listed. Both phones are priced at ₹30,999, so price does not separate them. Most other categories remain under-verified, which is why no overall winner can be named with confidence. Buyers should mainly decide based on battery priority versus the appeal of a more clearly specified chipset on the Oppo.
