The Xiaomi Mi A2 (US | UK | MY) has 8% faster gaming performance than the Realme 2 Pro, despite being powered by the same SoC. This makes it just 15.5% slower than the flagship-class Kirin 970 used in the Honor Play, and 74% faster than the Exynos 7885 used in the Samsung Galaxy A7 2018.

Battery life is a sore point for the Qualcomm Snapdragon 660. It is powerful, but it is a 14 nm chip that guzzles power compared to newer chips built on the 10 nm or 12 nm process technology.

Hence, we are not surprised to see the Xiaomi Mi A2 (US | UK | MY) last just over 5.5 hours in our stress test. Let’s remember that it only has a 3,000 mAh battery, while the Realme 2 Pro, which uses the same Snapdragon 660 SoC, comes with a larger 3,500 mAh battery.

 

Battery Recharging Performance

The Xiaomi Mi A2 comes with a 10 watt fast charger. Let’s take a look at how fast it recharges the 3,000 mAh battery.

Xiaomi Mi A2 battery recharging speed

The Xiaomi Mi A2 (US | UK | MY) took just under 108.5 minutes (1 hour 48.5 minutes) to recharge its battery from 20% to 100%. That’s an average performance, considering it’s using a 10 watt charger.

That is a battery life : recharging ratio of 3:1. A rule of thumb – for one hour of battery life, charge it for 20 minutes.

The fastest recharging happened up to the 90% level. This took just 71 minutes. Then the recharging speed slowed down, and it took a further 37.5 minutes to top up the remaining 10%.
