My friend have own an oppo a3s . The phone is decent .. Oppo a3s has 4230mah non removable battery .. It takes 2.5 hours to charge fully. And it goes about a full day if you are a normal user . You can play PUBG in 3GB ram and 32 GB rom phone . Its look is awesome . I am an yoituber so i usedthis phone for some days . If you are looking for a phone at budget 9000 then you can go for realme 3 or samsung m10 or asus zenfone max m1 .
