Our Verdict

On paper the Xiaomi ngươi 4C is an excellent mid-range android phone, with a fantastic spec for the money – it’s half the price of the Nexus 5X & can be just as fast. There’s a generous battery, a fairly good camera and some interesting new features such as USB-C. However, our benchmarking showed overheating to be a problem, và the issues we experienced with software out of the box make it difficult lớn recommend to lớn less techie users.

The Xiaomi mi 4C looks on paper (and in the flesh) lớn be a fantastic device, half the price of the similarly speccedNexus 5Xwith performance that can be just as fast. But ‘can be’ is the key point here, as overheating issues plagued our review sample during our benchmarks. We’ll talk more about this in the Hardware &performance section of this review.

We also had issues with some less-than-user-friendly preinstalled software, although these were easily rectified as we’ll discuss in the Software section. Also see: Best apk phones 2015/2016.

Xiaomi mi 4C review: Price và UK availability

The Xiaomi mày 4C is available in two versions: the standard mã sản phẩm with 16GB of storage và 2GB of RAM, as reviewed here; and a 32GB of storage, 3GB of RAM ‘Advanced’ version that should offer improved performance.

Xiaomi doesn’t officially sell its phones in the UK, so if you want to lớn get hold of one you’ll need khổng lồ buy it from a Chinese website that will ship to the UK.However, be warned that if you are shipping this phone lớn the UK from china you may also have lớn pay import duty – read our advice on buying grey-market tech.

Our standard Xiaomi ngươi 4C was supplied by Geekbuying, which charges £159.20 at the time of writing with không tính phí shipping khổng lồ the UK.This version has a very closely matched spec lớn the 16GB Nexus 5X, which is available in the UK for £339 – more than double the price of the Xiaomi mi 4C. Check out our review of the Nexus 5X.

Geekbuying also sells the mi 4C Advanced for £180.41 at the time of writing. If we were a paying customer we’d be inclined lớn opt for this version, given the small difference in price, the expected improved performance and the fact that there’s no possibility of expanding storage via microSD in either model. (There are other ways khổng lồ add storage lớn Android, of course.)


Xiaomi mi 4C review: Design và build

For a £150 phone made of plastic (albeit with a metal inner frame for enhanced rigidity and durability) the Xiaomi ngươi 4C is actually really quite good-looking. Athin slab just 7.8mm thick, it hasa soft-touch coating that feels great in the hand. There’s no creaking or flexing – this phone feels very well made.

The screen-to-body ratio is high, with some pretty slim bezels. For a phone that has a 5in screen the mày 4C is extremely well proportioned, just 138.1×69.9mm. It’s also lightweight, at 132g, without feeling like a toy. Also see: Best budget phones 2015/2016.

If you’re thinking the Xiaomi mi 4C looks familiar, that’s because it’s identical lớn the ngươi 4i. In fact, it is pretty much the mi 4i with a Qualcomm Snapdragon 808 cpu inside & the addition of a futureproof USB-C port for data transfer và charging. Also see: Best MiFi 2016.


Available in black, white, pink, xanh or yellow the Xiaomi mi 4C can be elegant or fun in its appearance. The rear cover is not removable, though, so be sure which mã sản phẩm you want before you buy. Our đánh giá sample is white.

You’ll find buttons & connectors in all the usual places, with a metal-effect volume rocker và power button high up on the right edge, a 3.5mm headphone jack và IR blaster at the top, a dual-SIM tray that pops out from the left edge và a USB-C port on the bottom. Turn over the phone and there’s a 13Mp camera with two-tone flash in the upper left corner, và a speaker grille that is slightly raised offthe surface of a desk by a small plastic protrusion lớn help prevent the sound being muffled.


The screen is a plus point, with a 5in full-HD (1920×1080 pixels) IPS panel with a sharp pixel density of 441ppi. Contrast is excellent, though the screen could be brighter – we found ourselves using it at maximum brightness at all times.

That said, this is a ‘Sunlight display’ that is claimed to be much easier to view in all conditions. We weren’t blessed with any sunshine at the time of our review, but we certainly didn’t have any problems reading the screen outdoors.


Aslight quibble with the screen is that we’re not convinced it will fend off accidental scratching too well. It’s rather keen on fingerprints, too. Also see all apk phone reviews.

Xiaomi mi 4C review: Hardware& performance

The Xiaomi ngươi 4C has the same chip core hardware as the Nexus 5X, with a 1.8GHz hexa-core Qualcomm Snapdragon 808 64-bit chip, Adreno 418 graphics và 2GB of LPDDR3 RAM (3GB in the 32GB Advanced model). Both feature full-HD IPS screens, although the Nexus’ is slightly larger at 5.2in against the Xiaomi’s 5in. On paper, performance should be very closely matched.

And it is – when the Xiaomi ngươi 4C is cold. (You can compare the Xiaomi ngươi 4C’s performance lớn other apk phones we’ve recently tested in our article What’s the fastest smartphone?)

When we first tried khổng lồ run our usual benchmarks they were plagued with pop-up adverts from various preinstalled apps. This isn’t a problem with the xiaomi mi MIUI 7 operating system itself, rather the version of the software that was preinstalled before the phone was shipped to lớn us. Having rectified this issue (we’ll explain how in the Software section) we were able to lớn install our benchmarking apps & run them without interruption. AnTuTu had lớn be sideloaded, but it ran fine.

On our second attempt we found very good performance that is right up there with the Nexus 5X. In Geekbench 3, for example, we measured 1251 pointsin the single-core component và 3233in multi-core. By comparison, the Nexus 5X scored 1240 single-core và 3528 multi-core. But each time we ran Geekbench 3 the mi 4C began to lớn heat up & our results very quickly fell off a cliff – to the extent that we were unable lớn get higher than 650 points single-core and 2027 multi-core. See all smartphone reviews.

We also ran AnTuTu on the Xiaomi mày 4C from cold & recorded a very good 54,250 score. When the phone began getting warm this dropped to 44,818 points.

We saw the same results in every benchmark we ran. In SunSpider (using Google Chrome) we recorded 496mscold, which is incredibly good, but1369ms warm (lower is better in this test). The Nexus 5X averaged 672ms.

We also ran the intensive GFXBench graphics test. The 5X completed this kiểm tra with results of 16fps in Manhattan & 38fps in T-Rex. Despite housing the same processor & graphics cpu the Xiaomi mày 4C could handle only 15fps in Manhattan và 34fps in T-Rex. As it became warm, this dropped lớn 11fps in Manhattan and 23fps in T-Rex.

These aren’t small differences we’re talking about here. It’s important to lớn point out thatthe Xiaomi mày 4C feels fast and responsive in real-world use, but our benchmark results show how performance can rapidly deteriorate as you use the phone.

It’s also worth pointing out that the Advanced mày 4Cshould be faster with its extra gig of RAM, but we can’t promise that it won’t suffer the same overheating issues. The Advanced version does, however, offer an extra 16GB of storage, which will likely prove useful given that the preinstalled software takes up a huge chunk of that available (just over 10GB is available lớn the user) & the fact there’s no microSD slot.

It’s not all doom & gloomwhen it comes lớn performance, though. Despite its dinky shell the Xiaomi ngươi 4C is fitted with a generous 3080mAh battery that supports Quick Charge over USB-C (and is supplied with a compatible charger). It may not be removable, but you should get two days of use out of this app android phone (slightly less if you take advantage of the Xiaomi’sdual-SIM capability).

Xiaomi mi 4C review: Connectivity và extras

The Xiaomi ngươi 4C can accept two Micro-SIM cards. It’s a dual-standby model, although both SIM slots can tư vấn 4G. Unlike some other Chinese dual-SIM phones we’ve seen, you cannot use the second SIM slot to insert a microSD card. Also see: Best dual-SIM phones 2015/2016.

When buying a phone from abroad you should always check the frequency bands it offers khổng lồ ensure that it will be compatible for your trang chủ network. Those in the UK should lưu ý that this Xiaomi mày 4C does not tư vấn the 800MHz LTE band, which means O2 customers (and customers of operatorsthat use O2’s network, such as GiffGaff) will not be able khổng lồ use4G data. The 1800MHz & 2600MHz 4G LTE bands are both covered. Also see: How to check whether a phone is supported by your network.

A standout feature here is the IR blaster, which we’re seeing in fewer flagships these days. The mi 4C also supports 802.11ac Wi-Fi, bluetooth 4.1, GPS và GLONASS, OTG và Miracast. NFC is not supported, và neither is there a fingerprint scanner, but there is a reversible USB-C data transfer & charging port, which we should see in more and more game android phones throughout 2016.

Xiaomi mày 4C review: Cameras

The Xiaomi mày 4C is fitted with a 13Mp Sony IMX 258 camera with phase-detection autofocus and a two-tone flash at the rear, & a 5Mp front camera. You can switch between the two cameras with a swipe up or down on the screen.

The selfie camera on the whole works very well. However, we noticed in our testing that it will try khổng lồ work out how old you look in the shot. & it had some difficulty in deciding whether it was looking at a 25-year-old female or a 50-year-old male. One I would take as a compliment, & the other a little rude.

Real-time filter previews are accessible with a swipe in from the right side of the screen. Swipe in from the left khổng lồ access all the usual shooting modes including HDR, Panorama, Fish eye, Tilt-shift & Beautify (note that these aren’t available for the selfie camera). In Manual mode you can control the white balance, focus, exposure time & ISO. đoạn clip recording topsout at 1080p. Also see: Best phone camera 2015/2016.

Our chạy thử shots from the Xiaomi mày 4C were reasonably good, full of detail and with great colours. HDR improves things, & we’d recommend leaving it on all the time. You can see a couple of our thử nghiệm shots below.

Here’s a 100 percent crop of the photo above: detail is a soft in places, but we couldn’t work out if it was post-processing causing the issue, or the lens.

Edge Tap lets you tap the left side of the device (the đứng đầu when held sideways) phối the focus, & a second tap triggers the shutter. However, this is bad idea: you’re shaking the camera và there doesn’t appear lớn be any image stabilisation khổng lồ compensate (not that we can fault the mi 4c at this price). Here’s what happens when you tap – even lightly – khổng lồ take a photo. Parts are in focus, while other parts are blurred. Look at the clock tower, too – it’s wonky.
