My dad is using this mobile.battery is excellent it lasts for a whole day.my dad 3g stays always on, i play coc and have 2 account along with clash royal and sometimes subway surfer so guys I think u got how much services the 4100mah li-po battery.
display and fingerprint sensor is working perfectly, beautiful display, good performansive screen.
ram memory is same as like perivous but it is ok
camera is good no drewback
there is some problem also like:the phone gets heat after continous usage of 3g, wifi no heating.remember it has a metal body.if you are looking for a smart phone with not so big screen and easy to handle with best specification around 10k your search ends to redmi prime I am not an expert but I write it what I felt.it is great mobile.you can buy it without thinking.
