Hii guys mi redmi a1 has a very good battery. And xiaomi a1 has 4100mah battery. When he was complete charge and when you may only talk then he moves 24 hour and when you are show vedios and sing a song then he moves 20 hour. And when uou are use on the net then he moves 14 hour when he was full charged. So my advice is this is better for you and I hopes you will buy mi redmi a1. When you done you always happy .
