Xiomi Mi4i is a quite good device. Better to use for the average use. Camera quality of this phone is better than other phones in price for this range. Battery backup is good but we cant say it is awesome. If you are using this phone for full day with internet aceess then you have to charge this cell more than two times in a day. But as per the part of price is concern this may be the best phone ever you may buy. Design quality of this phone is very good. It looks attractive in your hand. It is available in different colours. Dark grey colour is very attractive. So u may buy this budget phone with good efficiency.
