Xiaomi Mi 6 review: Social climber
Display
Much have changed since the Mi 5, but the display is not among the long list of upgrades. The Xiaomi Mi 6 uses a 5.15" IPS LCD with 1080p resolution. We're already used to seeing QHD screens on flagships but on a screen of this diagonal, we're quite content with 1080p as well.
The pixel density of 428ppi is great and provides a very sharp image. Xiaomi promises 600nits of maximum brightness and 1500:1 contrast. Putting those claims to test, we can confirm we got exactly 603nits or maximum brightness. Unfortunately, the contrast ratio was not as good as advertised. Due to the not-so-deep blacks it only managed to achieve 1305:1, which is quite good too.
The Mi 6 offers a minimum brightness of just 1.2 nits, great for late-night reading.

The Xiaomi Mi 6 managed to surprise in our sunlight legibility test scoring as high as an AMOLED panel would.

You can choose from three different options for the screen's color calibration. The default one is Automatic, which also optimizes the contrast dynamically in response to the available ambient light. When you use the phone in bright light, it would brighten up any dark on-screen areas to make them better legible.
The standard contrast mode doesn't have that but it offers very accurate color rendering with an average DeltaE of 3.2 and maximum deviation of 5.8 in the whites.
Finally, there is the Increased Contrast, which visually oversaturates all colors, in case that's your thing.
Additionally, there is a Reading mode similar to Apple's Night Shift. It removes the blue hues in line with recent trends as they potentially interfere with your sleep quality when you use the device just before bedtime. For extra convenience, you can configure this mode to be enabled only for selected apps.
Battery life
The Xiaomi Mi 6 has a sealed battery of 3,350mAh. That's a 10% improvement over the Mi 5. The phone supports Quick Charge 3.0 and the supplied charger can fill up to 55% of a depleted battery in 30 minutes.
We ran our battery test and the Xiaomi Mi 6 scored an 80h rating, which surprisingly is lower than the Mi 5's rating. The culprit is the Mi 6's relatively high power draw in standby mode because otherwise, it scored better in the three individual test of calling, web browsing and video. This unusual power consumption in standby might be software-related and fixed with a future update.
Our endurance rating stands for how long a single battery charge will last you if you were to use the Xiaomi Mi 6 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 6 is well-stocked with connectivity options, mostly due to the well-equipped Snapdragon 835 SoC. The Mi 6 offers LTE at Cat. 16 with impressive 1Gbps of download, courtesy of the latest Qualcomm modem with 3x carrier aggregation.
Unfortunately, unlike other flagships, the Mi 6 has very limited LTE support of just 9 bands. While it supports the widespread band 3 and 7, it omits band 20, which may be a problem in some EU countries. So, if you consider the Mi 6 and you want to use LTE networks, just make sure it supports your local band before you buy.
The Xiaomi Mi 6 also comes equipped with dual-band Wi-Fi a/b/g/n/ac with 2x2 MIMO antennas for speeds up to 867Mbps (if you have a compatible router). The local connectivity list goes on with Bluetooth 5.0 with aptX and Low Energy, and NFC.
The Wi-Fi connection can be used for screen casting - be it Miracast, Google Cast, or DLNA.
GPS, GLONASS, and BeiDou satellite positioning systems are supported, but apparently, the Mi 6 omits Galileo support.
The Xiaomi Mi 6 has no FM radio. There is no audio jack either, but Xiaomi provides a proper USB-C-to-analog jack adapter.
The USB port is Type-C but we can't confirm whether it's 2.0 or 3.x. Still, it lets you hook up USB storage and accessories and charge other devices.
