Xiaomi Mi 5X review: Popularity contest

Display

The 5.5" IPS display of the Mi 5X is very common among the Xiaomi smartphones, especially at the Redmi Note series. So, there are no surprises with the screen unit chosen for the Mi 5X - it has a 5.5" matrix with RGB arrangement and 1080p resolution.

Xiaomi promises 450 nits of maximum brightness for the Mi 5X's screen and a contrast ratio of 1000:1. We did our display test and it revealed a maximum brightness of 470 nits and one of the deepest blacks we've seen on an LCD screen. Thanks to those impressive black levels and above average brightness we got a top-notch contrast ratio of 1738:1. The color reproduction turned out about average, with an average DeltaE of 7.4 and somewhat punchy colors (especially the blue hues).

We then dug into the settings and change the screen's contrast from Auto (the default option) to Standard. The maximum brightness went as up as 550 nits while the deep black levels didn't take a hit and thus the screen kept its excellent contrast. The color rendering changed significantly - we got an average DeltaE of 3.7 where all colors were toned down to very accurate levels.

The sunlight legibility is okay on the Mi 5X - it suffers from washed-out colors in the sun, but other than that you will be able to see what's happening on the screen quite well.

Battery life

The Xiaomi Mi 5X has a 3,080mAh battery, not as impressive as the 4,000 mAh unit inside the Redmi Note 4, but the energy efficient Snapdragon 625 should help it achieve some good battery endurance. The Mi 5X supports regular 5V/2A charging, which restores 25% of the battery in 30 minutes of charging.

Indeed, the Snapdragon 625 chip once again lived up to our expectations. The Xiaomi Mi 5X scored an excellent 80h endurance rating. It did a fabulous job in all tested scenarios - video, calls, web browsing and demonstrated above average performance on standby.

Our endurance rating denotes how long a single battery charge will last you if you use the Xiaomi Mi 5X for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.

Connectivity

The Xiaomi Mi 5X is a dual-SIM phone with LTE connectivity. The slot is a hybrid solution and allows you to replace the one of the nanoSIMs with a microSD card.

There's also Wi-Fi ac, Bluetooth 4.2 is also available. For positioning, you get GPS, GLONASS and, quite naturally, Beidou.

The IR blaster is located at the top of the phone, and coupled with the right software, you can use it to remotely control pretty much any IR-enabled home appliance. Xiaomi provides its own MiRemote app, which supports a long list of devices right out of the box.

The USB Type-C supports USB On-The-Go with the proper adapter in case you need to access some external storage or use a USB accessory.

Finally, there is FM radio with FM recording available on the Mi 5X.
