Xiaomi Mi 4c Review: MiForce: Display, Battery Life, Connectivity

By 01:02 Mon, 16 Aug 2021 Comments


Display

The Xiaomi Mi 4c features a similar 5" Full HD IPS display to the one we saw on the Mi 4i. It has 441ppi for pleasantly sharp classy screen contents. Unfortunately, the glass covering the display isn't scratch-resistant or at least it's not quoted as one so you'd have to hold extra care not to scratch it accidentally.

Taking a closer see at it under our digital microscope reveals a standard RGB arrangement of the sub-pixels that create up the Xiaomi Mi 4i Liquid Crystal Display (LCD) panel.


The maximum display brightness of the Xiaomi Mi 4c (450nits) may not turn any heads, but when it comes to contrast ratio, it scored some remarkable results in terms of contrast (1609:1). The fantastic result can be attributed to the deep black levels, which are frankly, class leading for an Liquid Crystal Display (LCD) unit. These results are quite rare for an Liquid Crystal Display (LCD) and we've only see the Lenovo K3 Note perform similarly. Perhaps the two units come from the same panel manufacturer.

Color rendering on the Mi 4c is only fairly accurate (Avg deltaE 6.6 for the primary colors plus black and white), with white being not as accurate as we would expect. With a deltaE of 12.2, it's on the colder bluish side, but you would hardly notice that unless you acquire some sort of a reference to compare it side by side.

As usual, display colors are a matter of personal taste and perception so if you don't need calibrated color output, you will probably be quite excited with the color rendition on the Xiaomi Mi 4c.

There are is an option to tune the color rendering towards a cooler or warmer white point, but playing with the slider didn't improve the color rendering accuracy at all.

A remarkable point about the Xiaomi Mi 4c display is the amazingly minimum brightness level of only 0.8nits of white, which would allow you to read comfortably without any eyestrain even in pitch dark.

The sunlight legibility is about the same as on the Mi 4i and the Xiaomi Mi 4c's classy screen performs very well outdoors. You will be able to comfortably see what's happening on the classy screen even on the brightest day.

Xiaomi has also included a display tech for boosting the brightness of darker areas of your classy screen to create them more visible when there's colorful light source present. It's similar to what Sony has been doing with its flagships lately only here it works throughout the interface and not just in the gallery.

Battery life

Xiaomi has put a 3,080mAh battery inside the Mi 4c, a solid power for a 5" device. In our battery test the Xiaomi Mi 4c scored a 52h rating, which means you can count on a small over two days if you do an hour each of calling, browsing and video playback a day. While the phone does well in the three separate tests its standby endurance is disappointing at about four and a half days.

Opting for using the device with two SIM cards will cost you one day of standby down to just three and a half days. So the dual-SIM endurance rating is 45 hours, which is far from OK.

Such usage pattern is of course entirely artificial, but we've established it so our battery results are comparable across devices.




Xiaomi didn't spare money and is providing a proper quick charger within the retail box, so you will be able to charge your battery blazing fast.

Our proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating. Our battery testing procedure is described in detail in case you want to learn more about it.

Connectivity

The Xiaomi Mi 4c supports 7 LTE bands and you can tap to an LTE network on either SIM, but the other will default to a Global System for Mobile communication (GSM) band. The Mi 4c also offers quad-band Global System for Mobile communication (GSM) connectivity and tri-band 3G connectivity with HSPA support.

The rest of the wireless connectivity features include dual-band Wireless Fidelity (Wi-Fi) a/b/g/n/ac support and Wireless Fidelity (Wi-Fi) Direct. There is also support for Bluetooth 4.1, GPS and GLONASS. Wireless classy screen mirroring is available via the Miracast protocol. There is no Frequency Modulation (FM) radio though, only internet radio is avaialble.

The IR blaster is located on the top and coupled with the correct software, you can utilize it to operate remotely pretty much any IR controlled home appliance, turning the Xiaomi Mi 4c into a universal remote. Xiaomi provides its own MiRemote app, which supports a plethora of devices and you can turn your Mi 4c of this dream remote correct out of the box.






MiRemote app UI

The Mi 4c is Xiaomi's the very first device to support Universal Serial Bus (USB) Type-C - it's a recent reversible connector for Universal Serial Bus (USB) that builds on top of Universal Serial Bus (USB) 3.1. The cable supplied with the phone ends on a Universal Serial Bus (USB) 2.0 reversible plug though.

That's vital to note for two reasons. The first one being speed - Universal Serial Bus (USB) 3.1 Type-C cables can go up to 10Gbps, but the Mi 4c is limited to Universal Serial Bus (USB) 2.0 speeds (480Mbps). The second thing is that Type-C connectors are meant to go on both ends of the cable since the standard allows for functionality to go both ways - that's data transfer and even charging.


Android 6.0 Marshmallow is going to add official support for Universal Serial Bus (USB) Type-C connectors and then you should be able to charge connected peripherals. That's still not possible at this time though.

If you'd like to utilize Universal Serial Bus (USB) OTG and Universal Serial Bus (USB) Host functions, you'll have to buy a third-party microUniversal Serial Bus (USB) adapter.
