Completed a year of using this. Still runs 2 days on normal use. One and a half under heavy use. Gets regular updates, too. Not of the OS, but just security patches and MIUI, which I am happy with. If you don't need to showboat, this is all the phone one would ever need. Its successor, the Redmi 5 has only become larger, heavier and gets a smaller battery. The Redmi 6 doesn't even used an SD processor. All Xiaomi needed to do update this phone is slightly trim the top and bottom bezels, retain this 5-inch 16:9 screen, put in the latest SD 4xx or 6xx processor, put in USB C, perhaps enable it with FHD and call it a Redmi 7. I came to MIUI after 3 years of plain Android (JellyBean to Lollipop). And after one year of MIUI in this, I tried Android Oreo on a Sony flagship. Though I loved the hardware, I found plain Android tiresome after MIUI. I returned the Sony and am happy to be back to the Redmi 4. I wish small screens -- 4.3 to 5-inch (16:9) notchless phones were still made.
Now Quick Charging is available after a system upgrade. Please check it.. Seems RedMi 4X is the best budget phone now..
Miui 9.xx (whatever= is not reliable, I switched versions to get errors removed such as problems with screen rotation or black screen, kind of worked. Question is what is next? I need a phone that works not one where I can constantly update my understanding of current phone technology. Android, apple os, blackberry os, windows 10 worked ok for me, Miui does not.

In call sound quality is questionable at best. I can hear others well, but my call mates are complaining about my voice come and go.
This is so disappointing for an otherwise great device.
If this isn't a problem for you, go buy it. For me, it's a deal breaker.
So, why exactly telephony test has been left out...?
Does it support chat head and pop up notofication for fb messenger and whatsapp messenger??
I dont find it anywhere

Worst product ,don't have the quality to put garbage box...Too much radiation feeling....It is buying cancer from 13k....Better to choose company phone like i-phone or Samsung than this low quality & hazardous product.spreading too radiation.I didn't cheat this much from any company....I'm too eager to put my review..If any have doubt about the purchase ,I will post the bill from eBay....Don"t waste your money for low quality mobile.should enquire customer comments before purchasing Redmi note 4.....
I have used this fone for a week now and I can say it's really amazing.. Slightly heated while charging... It has a premium feel and look of a flagship and no lags at all..... This my first Xiaomi and am loving it already
I hv 2set redmi 4 and 1 set redmi 4a all hv same Mic problem when we make a call our voice cme and gone.i think its network problem but not it hv mobile problem .its a biggest error in this series pho your voice come and gone when you call.i m very desprate and hv not time for go to mi store to fix this problem.my personaly view dont by this pho look at other brand or try redmi note series.
I bought my son redmi 4x 16gb/2gb ram last june, he liked it everything on the phone, charges fast enough but one thing he doesn't like is, it doesn't have a transfer to sd card feature. And what i read about all xiaomi phones doesn't have this feature (what is xiaomi 's reason for doing this) But overall he's enjoying using the phone.
Anonymous, 07 Jul 2017I'd like to correct you. Actually, the low price is simply the icing on top of this phone. It ... moreIt's a different story when phone arrives at EU. The price becomes in euro plus 20% taxes , plus little more for the retailer. Then is not that much bargain. Anyway look now at Redmi 5. Much better spec for around same price as Redmi 4. Much better.
This phone should be equipped with
Minimum Gorilla Glass 4 ,even better if GG5
Phones are fast Good Ram memomry, enough Rom best memory, but once dropped everything is gone,
Repairing cost are much expensive,
I've bought Meizu, but glass is broken
Repairing is costs almost near to buy a new phone
Anonymous, 07 Jul 2017O really??? I had moto g4 play for 2 month. That before I was using redmi 2 prime. I agree mot... moreThe Redmis don't heat up more than usual, their temperature is on par with other phones, I compared the internal temperature on my new Redmi 4x and my old Allview P6 Energy. The problem is the material they used - the all metal body is much better temperature conductor than plastic and heat dissipates more. And that's why when the cpu is 40 degrees it feels much hotter on a metalic phone than on a plastic one.
