IUNI U2 review – Snapdragon 800, and flagship features at a low price


iuni u2 review

IUNI started life as the maker of custom ROM IUNI OS, but like Xiaomi before them, have branched out in to the hardware market with their own high specification flagship phone. Read the IUNI U2 review here.

$290 can get you a lot of phone these days, well it can if you are lucky enough to live here in China. The IUNI U2 is the first smartphone from this young custom ROM maker and from just 1799 Yuan ($290) you get a heck of a lot of phone for your money!

IUNI U2 Specifications

There are two variants of the IUNI U2 the only difference between the two phones being the amount of internal memory and either 2GB or 3GB RAM. This review (translated from the original Chinese review here) is based on the 2GB version of the phone.

The 2GB RAM 16GB memory IUNI U2 is on sale in China for only 1799 Yuan, where as the flagship 3GB RAM 32GB memory version is just 1999 Yuan! That’s cheaper than the Xiaomi MI3, with better hardware, more compact design and screen with a much higher PPI!

IUNI U2 Review – design

iuni u2 review

IUNI have created the U2 has a unique alternative to mainstream smartphones. The body comes in a choice of either silver (seen here), black or green. Each phone is machined from a single block of alloy making for impressive build quality for such an affordable smartphone.

iuni u2 review

With just a 4.7-inch display up front, and narrow bezels, the IUNI U2 is one of the most compact flagship smartphones on the planet, the actual dimensions being 139 x 65 x 10.2mm (that’s measured to the tip of the protruding camera on the rear) at a weight of 145g.

iuni u2 review

From the rear the IUNI U2 seems to have taken a dip in the wardrobe of the HTC One and has the same 3 stage rear with simple bands separating each section of the phone. The middle section is the largest and is also where we see most of the action, that action being a 16 mega-pixel main camera with a single LED flash.

iuni u2 review

Over to the front and we can see those narrow bezels up close, and the front camera. Interestingly the front camera is a 4 mega-pixel Ultra-pixel unit, similar to the sensor found on the newly launch HTC One M8 smartphone.

Looking at the front we also get our first glimpse of IUNI OS, the custom ROM which IUNI produced for their flagship phone, and is also available for certain Samsung phones and soon the Xiaomi Mi3. At this point owners of the Gionee Elife E7 might be having a bit of deja vu! Not only does the IUNI appear to be a mini version of the Elife E7, but that ROM certainly has a familiar Amigo UI look to it also!

iuni u2 review

No on screen controls for the IUNI, personally I prefer on screen buttons, but fans of backlit capacative buttons can rejoice.

iuni u2 review

As for physical buttons there is a small power button on the top to the left of the 3.5mm headphone hack, and a volume rocker an the right in a great location for your thumb.

iuni u2 review

The base has been perforated on each side with 20 small holes for the external speakers, between which a Micro USB plug sits in wait for charging and transferring data.

iuni u2 review

Finally the left hand side is where you will discover the single SIM card tray for GSM or WCDMA 3G cards. As you might have seen the body is of unibody construction meaning that the 2200mAh battery is sealed in to the phone. There is also no space for a micro SD card.

IUNI U2 Review – Display

Since the start of 2013 smartphones have gradually become larger and larger. First there were 5-inch 1080 phones, and this year most flagships have gone for between 5.1-5.5-inch 1080 displays. IUNI buck that trend and once again go for the more unique option of a 4.7-inch panel.

iuni u2 review

Not only does a 4.7-inch panel mean the phone itself will be physically smaller, but due to the fact that the display has a full 1920 x 1080 FHD resolution the pixel density is much higher than that of a Xiaomi Mi3, Gionee Elife E7, or even the mighty Oppo Find 7a!

LTPS and IPS mean that colours are bright and vibrant, touch response if fast and you can get away with using the phone with gloves on.

IUNI U2 Review – IUNI OS

iuni u2 review

One of the reasons IUNI made the choice to launch their own phone is to highlight their own ROM.

iuni u2 review

It’s hard to make any custom ROM look truly unique these days, and there are always some feature, functions and UI decisions which will either be inspired from other ROMS or will eventually make their way on to rival devices.

iuni u2 review

IUNI have gone for the popular flat design language giving the interface a similar overall design to iOS 7, Nubia UI and Amigo OS. However the ROM is extremely well though out and personally I feel it is one of the better looking ROM options available today.

Being a newish ROM the majority of features are exactly the same as what you would find on any flagship phone, but has development hots up we are bound to see some nice surprises and unique ideas from the IUNI OS team.

IUNI U2 Review – Performance

iuni u2 review

The model on review here is the Snapdragon 800 2GB RAM model. Without testing the phone with Antutu we can already guess that performance is going to be stunning.

For those of you who need the numbers though, Antutu gives a score of 34,529 points! Thats more than the Xiaomi Mi3, and the Sony Xperia Z Ultra. The flagship 3GB RAM model could have the power to take on the Samsung Galaxy Note 3!

IUNI U2 Review – Battery

Looking at the hardware the weak point appears, at least on paper, the 2200mAh Samsung battery, but keep in mind that the IUNI has a smaller 4.7-inch display than comparable devices. According to the reviewers who tested the phone the 2200mAh battery uses around 67% of the battery.

40 minutes of video will eat 12%, and 20 minutes of social networking takes around 4%. Leaving the phone on standby overnight drains the battery by a mere 2%!

IUNII U2 Review – Camera

iuni u2 review

We are at a time in phone development that pretty much any phone can produce amazing photos. When it comes to smartphones at the same calibre of the IUNI U2 you can be sure that camera quality is going to be up there with the best of them.

The 16 mega-pixel main camera on the U2 produces high quality photos. Colour reproduction is assuage and even low light nigh photos are excellent!

Unfortunately the source review does not have full size photo samples for all the photos to share. Here is a link to one sample, I will upload more in future posts.

IUNI U2 Review – Conclusion

In a market full of large screen smartphones, the IUNI U2 makes for a unique and refreshing change. The compact body means one-handed operation is a real pleasure, the alloy body oozes quality and the high-resolution display is beautiful.

iuni u2 review

Hardware is something you just don’t need to consider with the U2. Everything from the display and cameras, to the Snapdragon processor and Samsung battery are all top of the line items and will keep even hardcore phone fanatics happy.

If you get a chance to buy one of these phones you really should give it a go. I certainly will be!

      Think again, please. The bezels are huge. With this dimensions, they could put a 5″ display there.
      In fact, is this downside that keep me away from this phone.

        side bezels aren’t bad. it’s 65mm wide; 3mm narrower than HTC One (4.7 inch). As narrow as the XPeria Z1 Compact (4.3 inch).

    Again -single sim. It is so difficult to add + 1 nano sim slot ?
    2200mah -weak battery. There is no wireless charging ?
    Button at the top? Clone of HTC? It’s not comfortable.
    http://1-ps.googleusercontent.com/h/www.gizchina.com/wp-content/uploads/images/640x426xiuni-u2-review-1.jpg.pagespeed.ic.gu_IinyvLw.jpg – Glare of the top of the screen or what is that?
    How is the brightness ?
    It should cost around 300 for international buyers. But even with this price i would think to buy this phone or not , 2200mah ?It’s just idiotic

    Who have seen this phone for this price 320$ ? For international buyers Chinese seller would give 400$ or much more. So i don’t know is it good for that price. As we know – all we buy from aliexpress e.t.c doesn’t have any warranty. Some of sellers say that they have it, but for real it almost not possible to make this procedure easy without brainfu….ing.
    So would you buy official phone in store with warranty or IUNI?

      IUNI any day. Step aside GS4, step aside HTC One, step aside Xperia Z1. This beast here is the real deal.

      • CryosR
        April 12, 2014

        Show we were to buy this phone for that price listed above?
        GS4- weak battery, problems with overheating.Not as bright screen as i want. But still good phone.
        HTC one – uncomfortable, low resolution camera, good body but nothing more.
        Xperia Z1 – bad screen. Giant borders around the screen.

        Maybe GS4 is not a worst variant at the moment.

        • Airyl
          April 12, 2014

          Yes, I would. Let me elaborate. The IUNI U2, even at $400, is a fantastic value for money, especially compared to the others I just brought up. It’s got a beautiful aluminum unibody design (also, I never found the HTC One uncomfortable, but that’s just me), it’s extremely speedy with it’s Snapdragon 800 processor and 3GB RAM, it has no bloatware, It’s got a really good resolution and size, the camera is high res and according to reviews, really good, it’s got a 4 UltraPixel front camera (damn), and on top of all that it’s quite affordable, even more so than the HTC One and Galaxy S4 which aren’t even as high specced as it is. The Xperia Z1 comes close, but it fails miserably in price. Even the Nexus 5 and Xiaomi Mi3 aren’t as good as this. That’s why I’d rather take this over a branded smartphone. If price weren’t a factor, I’d get a Find 7, but unfortunately I need to save my money as much as possible if I’m ever going to build myself a gaming desktop. I hope this explains my choice.

            April 12, 2014

            Maybe you could pay for such device 400$ but who need 3gb ram? Who need 34 000 in antuutu when even mtk6595 with its 27.000 is enough for any games . (i dont need it,im not a gamer,i dont play at all)
            But they didnt installed sd slot. No 2nd sim card.
            Why i cant choose by myself which card to install. And they just sell hardware that we dont use. 2gb ram is more than enough, but 2200 it is not normal, it could be ok with wireless charger.
            Even big companies have problems with their devices. Small company such as iuni should understand that we need outstanding features for our money.
            Why nobody ask which phone do we need?
            Lets make technical task for manufacturers with our reqirements, what we want to see in the phone and vote for design e.t.c

              April 12, 2014

              If you don’t need the 3GB RAM version, get the cheaper 2GB RAM version. I’m not much of a gamer either, but since when has more been bad? The question isn’t what phone do we need, it’s what phone do you want. I love the design, I appreciate the speed, I love the fact there’s no bloatware, the size is perfect for most people, the resolution is fantastic and it’s affordable enough that I can get one. What you want is a phone that isn’t cutting edge, but fits you. You want something with good battery life, a second sim slot and a microSD card, a comfortable design, and 2GB RAM. I’d suggest the Xiaomi Redmi Note, Doogee Dagger DG550 or JiaYu G4S for you. I still prefer the IUNI U2, but to each their own I guess.
