Hi frinds xiaomi Mi 4i is very good mobile
Very good Battery backup
I charge in fully and use continuously for 8-9 hours( even not taking 5minute rest) then it comes down to 10 %
Its a very good phone
You should go for it
VERY good phone, since I m playing heavy games like asphalt , modern combat , etc . And I do not notice very heating issue , yes it may heat but not so hight and a very good phone for normal users
Thankking you.
