Difference between OPPO A5s vs Vivo Y91


At a glance, OPPO A5s and Vivo Y91 both carry the latest smartphone designs, except that each smartphone carries a fairly thick characteristic from the manufacturer. Included in it, both have full screens with small bangs like water droplets at the top.

Both also have screens with the same resolution but have slightly different sizes. In this case, Vivo Y91 has a slightly larger size, although it doesn’t make the size look different.


The most different from the two devices is in terms of the chipset used. OPPO entrusted A5s capabilities to MediaTek’s chipsets, while Vivo entrusted Y91 to Qualcomm’s chipsets.

On paper, the chipsets used by OPPO are superior to those used by Vivo. Although both are built from the ARM Cortex-A53 with 12 manufacturing, the MediaTek chipset has a higher maximum speed.

The MediaTek Helio P35 chipset at OPPO A5s can be driven up to 2.3 GHz, while the Snapdragon 439 chipset on Vivo Y91 can only be driven with a maximum speed of up to 2.0 GHz.

In addition, the MediaTek chipset also has better LTE modem support. This is because MediaTek Helio P35 has a Category 7 (downlink) and Category 13 (uplink) LTE modem, while Snapdragon 439 only has Category 4 (downlink) and Category 5 (uplink) modem.

Simply put, MediaTek Helio P35 will have a faster modem because it can be used with a maximum speed of 300 Mbps for downloads and 150 Mbps for upload. For the record, Snapdragon 439 can only reach 150 Mbps for downloads and 75 Mbps for upload.

Battery Capacity

As shown in the comparison table, OPPO A5s have a larger battery capacity compared to Vivo Y91. Because it has an equivalent chipset manufacturing and some fairly similar specifications, OPPO A5s should be able to last longer.
