A 720p screen and the power-efficient Snapdragon 450 keeps the battery running for long, the 4,230 mAh battery can last up to 2 days on a single charge moderate use. This is good for those who don’t want to charge the phone every day, the OPPO A3s offers a great battery life.

Our usage was quite moderate, we played music and videos, streamed online content, played some games, used as a hotspot device, but the OPPO A3s didn’t give up on battery, it was surprising for us to see the battery was running great.

The ColorOS is also responsible for the better optimization of the battery. The OPPO A3s runs on the Android 8.1 Oreo with a security patch of 5th June 2018. You will find ColorOS 5.1 interface on top with a number of features built-in to it.

Other specs include a 2 GB RAM and 16 GB internal storage that expands via a microSD card on a dedicated slot. Other phones in this segment like the Xiaomi’s Redmi 5 comes with similar specs and a 3,300 mAh battery which is inferior to that of the OPPO A3s.
