This phone runs on a decent power efficient cpu.5.52inch screen, 2.02ghz processor, 4000mah lithium ion battery.all these specifications are not described on any website.ram and processor goes decent.display is good but could be better.camera is not very good.battary goes one day if the user is a heavy user.network captureing system is good but type of network selection is not on users control.front camera pictures are not good in low light.this phone has some decent performances along with some lack of quality.dont know why installed apps just expand in size without any extra data.redmi note 4 is very affordable model for the middle class peoples who needs everything in a low budget.it can give every taste but not the best.
