Xiaomi Mi A3 vs Xiaomi Mi A2: all changes and differences

ByTown Kassis 2019-07-30 4181

Less than a year has passed since the release of the Xaomi Mi A2, Xiaomi company announced the new generation of its Android One smartphone family - Xiaomi Mi A3. Although Xiaomi says the new version is the best to date, the Xiaomi Mi A2 introduced in 2018 became the world's best-selling Android One mobile by combining cutting-edge specifications with a modern design, and an extremely competitive price. The question is, will the new Mi A3 be able to stand up to it?

More size and less screen resolution

The change that is probably least likely to please those who were looking forward to the arrival of the Xiaomi Mi A3 is the reduction in screen resolution. From the 5.99 inch Full HD IPS panel of the Xiaomi Mi A2, we now have an AMOLED screen signed by Samsung, 6.08 inches diagonal with a resolution of "only" 1.560 x 720 pixels.

The screen, however, adds some extras such as the optical fingerprint reader integrated into the screen, or the arrival of a notch in the shape of a drop, which replaces the pronounced frames that surrounded the panel of the Mi A2.

We also found differences in its construction. For the first time in the Mi A series, it's time to say goodbye to aluminium to welcome the glass, as it's a Gorilla Glass 5 panel that occupies the back of the phone. However, this does not mean that the phone has received support for wireless charging, and the water resistance is still not present.

A more powerful processor... but not too powerful

The Qualcomm Snapdragon 660, although not one of the newest chips, has been able to deliver excellent results over the years, and was certainly one of the strengths of the Mi A2 over its rivals. This time, Xiaomi decides to take the leap to the next generation, and move to use the recent Snapdragon 655, somewhat more efficient than its predecessor to be manufactured in an 11nm format, and with eight Kryo 220 cores.

What doesn't change, however, are the internal memory configurations. 64 or 128 GB of internal storage remain the only options available, although we are happy to know that the battery has grown significantly to reach 4,030 mAh capacity. On the other hand, only a RAM configuration with 4 GB is now available, so the upper 6 GB version disappears.

Triple sensor arrives and selfies camera grows to 32 megapixels

We also see an important leap in terms of photography. From two we go to three sensors on the back of the phone, 48, 12 and 2 megapixels. The first is the same Sony IMX586 that mounts most smartphones this year, while the 12 megapixel is a wide-angle sensor that can capture more information from a scene and the last can only capture depth information. The telephoto lens we liked so much about Mi A2 disappears.

The changes also reach the sensor for selfies, as we go from 20 to 32 megapixels. While the jump is considerable, I'm afraid it will be the software that determines whether or not it's worth having a higher resolution sensor.

The verdict

On paper, the Xiaomi Mi A3 doesn't seem to be an extreme evolution. We see interesting changes, such as a better processor, a higher capacity battery or a more advanced photographic system. However, other aspects such as the lower resolution of the screen may lead more than one to decide for another alternative model to this new terminal with Android One.
