Xiaomi Mi4 poses for new pictures; is the back plate plastic or metal? (It's plastic!)

0. phoneArena posted on 20 Jul 2014, 12:50

Freshly leaked pictures of the Xiaomi Mi4, just days away from its July 22nd introduction, still do not end a mini-controversy about this upcoming flagship device. A sentence about the new handset, written in Chinese on Xiaomi CEO Lei Jun's Weibo account, was translated and apparently says something along the lines of, "The journey of a piece of steel metal." That would seem to indicate that the phone will be made of metal...

Stop worrying about material and worry about actual life and durability.

That's why HTC One, Z2, IP5, oppo7 feels and has a touch of class and prestige.

Great would you like one that's made of dustbin plastic...?

HTC One and and IP5 have issues with signal dropping out. Z2 has issues with over heating. Metal looks premium but is far from being a practical solution.

Sensible ppl chose phone for functionality like accessible battery, rounded corners for better grip, non-smooth back for better grip, etc. not for 'prestige' and 'class'

That's why Samsung sells more plastic then all of them COMBINED except iPhone ofc.

If everyone could afford to drive prestige cars like: BMW, Jag, Merc, Audi, who the he'll would want to buy or drive Ford, Toyota, Mazada, Nissan and Vauxhall.

People don't care about issues, aslong it has prestige, quality materials.

Personally me, I don't like cheap junk bendable dustbin plastic

When your paying €800 euros for a high end phone, we demand:

Carbon fibre
Stainless steel 18,8

Not cheap low grade low class tacky plasty

What is this obsession with metal? Newsflash, most people don't care. Fact, #1 selling premium android phone in the world is plastic. #1 premium phablet phone is plastic. Even, iphones are made mostly out of glass. (By the way, the cheapest car in America, Nissan Versa, is made out of metal.)

If they have issues, they should've used 4or 8 antenna, instead of 2 antenna.

Stupid Oems

Apple had to use 4 antenna, when they realised 2 was a fail.

The HTC One has issues with signal dropping out? I have mine for more than a year and it has pretty good reception, on par or better than many other phones. I didn't experience one single drop out with it...

Not on my end. My M8 has a little better dB gain than my cousin's S5 in the same places we went. So no the aluminum did not affect it. The amtennas are the black lines in the case if you didnt know.

samsung sale has nothing to do with plastic, its more about their branding.

Aluminum is the worst material for smartphones EVER? See how the backs of the M8 and iP5 is cut , but NOT WHOLE tin can.
How could you expect this Xiaomi Mi4 on the picture to be whole aluminium , and to work , at the same time?

"Feel" and "touch" have nothing to do with durability at all.

Xiao Mi phone stock are sold out in term of second. They sell directly to their customer via their online site. I did not manage to buy it the first round because I took 2 minutes to complete my purchase. My recent attempt is 30 second record time. Redmi Note is sold out in 42 seconds.

"Go premium, or go home."

The cheap aluminium tin can , - "premium"????? ROTFL

How could you expect this Xiaomi Mi4 on the picture to be whole aluminium back , and to work , at the same time, you ignorant?
ROTFL(check out how they cut M8 and iP5 backs , because aluminium doesn't work for smartphones)

Yes, yelled, because I want to BITCH SLAP anyone who likes them*

*when they take up the NORMALLY free screen space, if they were to extend the screen down where the buttons would NORMALLY exist, I would love them as well, currently however, there isnt a SINGLE PHONE/TABLET that does this**!!

**Link me if you know of one, and ill let you know if its enough

Actually ,soft keys are fat better than physical. I know they take place but that depends of the manufacturer. Look at the OnePlus One for the exemple.
Softkeys can be heavily modified with custom roms. you can have 3 4 or whatever buttons. And set them double function with longpress. You can also have the navigation ring. So yes softkeys are better when you use custom rom

Yeah but extra bottom bezels should have off screen buttons to preserve screen space, the Z2 should have off screen buttons

The Moto X does it. It has barely any bottom bezel at all. Same for the LG G2 and G3

would love to try this on T-mobile. I would pick this phone over the iphone 5 s or c any day of the week. At least companies like them are trying their hardest and not going all out like champions unlike Apple who made phones that can't keep up with the current trends. Apple are like peasants.

I don't understand why people want a metal cover, on a phone if it has an INTERNAL antenna. Yeah, if you had one of the phones back in the 90's that had the little nub sticking out of the case, or, one of the star-tac phones (I did and went through a lot of broken antennas), I could see the "coolness" of having a shiny metal back cover, but, since the antenna on a modern phone, is nothing more than a few micro layers of metal, or in the recent patient lawsuit of one that is "painted" on by a laser onto plastic by way of activating a new kind of chemical, you don't want metal anywhere near the antenna. RF signals have to go through that metal, to get to the antenna. At the microwave bands, it's possible some signal will not resonate properly through that metal, and it's still possible to get some harmonics bouncing around. If you were to take a phone, run a signal strength on it, then pop off the plastic back cover, for a metal one, you'd find signal degradation of a few db. That could mean the difference in a signal in the fringe area, and no signal in a fringe area. As hyper as people are today about "no bars" on their device, why would you want to. Plus, that metal cover is going to radiate heat, keeping it warmer, and, will reduce battery life. How? The stronger the signal on a cell phone, the LESS output power the transmitter emits to keep locked onto the tower. Weaker signals mean higher output, which means less battery. Plus, most phones I see today, are covered in a case, so why double the amount of heat trapped by having a metal case, surrounded by a layer of plastic, rubber, or both?

Even if it's metal or has a 1440p screen. I will still never fall for a phone from a Chinese brand like OnePlus, Mi (Xiaomi), or OPPO. I will loose my favorite features like an IR Blaster, Dual Front Speakers, Laser AutoFocus, and much more.

I take back whatever I said. That is one nice-looking device, especially with the new capacitive buttons
