The Xiaomi Mi6 was released in April 2017 and is equipped among other things with the high-end processor "Qualcomm Snapdragon 835". For this review, the smartphone accompanied me a little over a month as a Daily Driver. How my overall impression of the Xiaomi Mi6 turns out and whether a purchase is worth more about this in this review.

First impression of the Xiaomi Mi6

Design, workmanship and What's in the box

Visually, the Xiaomi Mi6 does a lot. The front is completely black, which makes the smartphone seem simple at first glance. On noble feeling gives the completely rounded and alloyed aluminum frame, the knot in the rounded on the sides Glass back passes. A disadvantage of the strongly shimmering glass back is the susceptibility to fingerprints. As already at Xiaomi Mi Mix, the smartphone was already literally littered with fingerprints after unpacking. No wonder Xiaomi also adds a protective cover to this smartphone.

With the front Starting at the bottom of the 5.15 inch large display, the home button embedded in the glass front, which also houses the fingerprint scanner, is located. To the left and right are two capacitive and white illuminated control buttons. Above the display is the optically barely perceptible auricle, which also acts as a second loudspeaker. Next to it is the 8 megapixel front camera housed. Also available is a proximity sensor not visible to the naked eye, as well as a white illuminated notification LED.

The housing frame on the right, the power button and above the volume rocker. Both buttons have a good pressure point and sit firmly in the case. On the opposite side is the SIM slot, which can be equipped with two Nano SIM cards. At the bottom of the case frame sits the USB-C socket in the middle, on the left next to it the microphone and to the right of it the loudspeaker. The Xiaomi Mi6 does not use an 3.5mm jack connection, so there is only one infrared transmitter on the top of the rack.

Finally, let's take a look at the back of the 145.17 x 70.49 x 7.45 mm and 168g heavy smartphones. As already mentioned, this is made of glass, which makes the smartphone a bit slippery in the hand. Remedy is the included silicone protective cover. On the reverse side, the dual main camera with a dual-tone LED flash is located on the top left. To round off the design, the main camera, as well as the LED flash without transition into the housing are embedded.

The scope of delivery around the Xiaomi Mi6 is a little more lush than it was with the predecessors of the case. Are included besides the typical Quick charger with NEMA-1 connector, the USB-C cable and the Manual and SIM needle, still a Silicone cover, as well as one USB-C to 3.5mm jack adapter.

The Xiaomi Mi6 convinces with a noble design and excellent workmanship. A disadvantage of the glass back is the somewhat slippery feel and the susceptibility to fingerprints.

Display

The built-in display is of type IPS and triggers at one Diagonal of 5.15 inches with 1920 x 1080 pixels on. Thus, the device achieves a pin-sharp dot density of rich 428 PPI, which is why individual pixels are not visible to the naked eye. By the used In-cell technology, whereby a much thinner panel can be manufactured, the display achieves a rich black value and a particularly strong color representation. If you do not like the color scheme, you can adjust it yourself within the display settings. The Viewing angles convinced. No matter what angle you look at the display, the color reproduction is retained, as well as fonts remain recognizable.

By the phenomenal Luminance of 600 Nit the display is easy to read even in strong sunshine. To protect the eyes, a reading mode can be activated, which filters blue light. It is also interesting that the display brightness can be lowered much further down than is possible with other smartphones. The automatic brightness adjustment functioned perfectly in the test.

The Touchscreen supports 10 finger multitouch. Entries are made by (presumably) Corning Gorilla Glass 4 protected display precisely recognized. Even after a few weeks and daily use without screen protector, no scratches have become noticeable.

The display impresses with an accurate and crisp presentation, a high luminance and a precise touch screen.

Performance

With the Qualcomm Snapdragon 835, the Xiaomi Mi6 has the latest high-end mobile processor from the manufacturer Qualcomm installed. The 64-bit processor is manufactured in the 10nm process and consists of a total of 8 Kryo 280 processor cores, which in turn are divided into a power and power-saving cluster according to the big.LITTLE architecture. The power cluster includes 4 cores that clock up to 2.45 GHz. The power-saving cluster also has 4 cores, which however have a clock rate reduced to 1.9 GHz. The processor graphics are an Adreno 540 GPU that promises high-end gaming performance.

The storage facilities Our Xiaomi Mi6 trial copy comes with a 6GB LPDDR4 memory and 64GB UFS2.1 flash memory. Optionally, the smartphone is also available with an 128GB large flash memory. An expansion of the memory by means of micro SD memory card is not possible!

In practice, the Xiaomi Mi6 proves to be extremely performant. Apps are instantly installed and open quickly. Even with intensive multitasking, no performance breaks are noticeable. Surprising, however, is the comparatively slow LPDDR4 main memory. In the benchmark, only RAM Copy Rates of 7000 MB / s were achieved. Other smartphones, such as the Xiaomi Mi5S, which is also equipped with LPDDR4 RAM, achieve values ​​of fast 17000 MB / s. Also, the UFS2.1 memory delivers in the benchmark from no brilliant performance and is below the possible. In everyday life, however, the slow RAM and UFS2.1 memory have not proved to be a disadvantage.

If you can not do without mobile games, the Xiaomi Mi6 is an excellent choice. The Adreno GPU 540 gets along well with all demanding mobile games. The heat development is low even with intensive use. After one hour of intensive benchmarking, the temperature measured on the back reached a maximum of just 40 ° C.

The Qualcomm Snapdragon 835 System-on-Chip is currently Qualcomm's most powerful system and is distinguished by its outstanding performance. Multitasking, mobile gaming and other tasks are no problem for the Xiaomi Mi6.

User Interface

As operating system comes MIUI 8.2 based on Android 7.1.1 for use. Depending on where you ordered the Xiaomi Mi6, a so-called shop ROM can be preinstalled, which usually can not be updated and also carries the risk of bloatware. If you get a Mi6 with a shop ROM, you should either flash the official Gobal ROM, or you can alternatively download the Xiaomi.EU ROM. It is not recommended to flash the smartphone to the original China ROM, because on the one hand the language selection is limited to a few languages ​​and, in addition, many apps intended for the Chinese market are preinstalled.

MIUI itself is far away from an Android stick. The user interface looks playful, but offers quite interesting features, such as themes, widgets and extensive settings options. An app drawer is missing from MIUI. Instead, apps are stored directly on the home screen.

Update 12. August 2017
It was announced a few weeks ago and has been available since yesterday. Xiaomi has the long-awaited MIUI 9 version upgrade published in a first public beta. In addition to the recently published Xiaomi Mi5X, which has already installed MIUI9 at the factory, the ROM upgrade was also delivered for the Xiaomi Mi6 and Redmi Note 4 or Note 4X. Anyone who already owns the Mi6 and has installed the latest Global Beta ROM will receive the update directly via OTA. All those who are on a different ROM can use the MIUI 9 Public Beta over this one article download and flash via fastboot method. The bootloader must be unlocked for this!

MIUI 9 promises an even faster user experience. MIUI has been completely redesigned for this purpose and offers not only design changes but also deeper changes that increase the performance of the user interface. Who dares to use MIUI 9 in an early version as a daily driver, the ROM should definitely flash!

camera

On the back is the dual main camera of the Xiaomi Mi6. This is made up of one 12 megapixel Sony IMX368 image sensor and another 12 Megapixel Saumsung S5K3M3 together. The Sony sensor uses one f / 1.8 aperture and is additionally with an optical 4 Axis Image Stabilization (OIS) fitted. The Samsung sensor with a f / 2.6 aperture allows 2-fold telephoto zoom, The front camera resolves with 8 megapixels.

Practical test of the main camera

Especially in terms of camera quality, Xiaomi lagged significantly behind other flagship smartphones. Only with the Xiaomi Mi5S was a clear increase in quality to recognize, although still potential was awarded here. With the dual camera used here, however, Xiaomi is well on the way to compete with flagship smartphones.

The main camera convinces with an accurate Bokeh effect (Foreground harsh - background blurred), which extracts even the smallest subtleties cleanly. The color representation of the pictures is convincing in good as well as in low light conditions. At the same time, picture noise in poor lighting conditions remains within acceptable limits. If it is too dark, the very bright dual-tone LED flash can be switched on.

Pluses the main camera also by the fast and accurate Autofocus, as well as the low precipitating trip time. Due to the double optical zoom, it is possible to zoom losslessly at the touch of a button without losing details.

Also for everyone video enthusiasts The main camera of the Xiaomi Mi6 also has a lot to offer, but this feature is more to criticize than the image capture function. The 4-axis image stabilization ensures for the most part jitter-free shots, even on high-resolution 4K. Xiaomi has completely renounced electronic image stabilization. Videos are recorded in 4K and at 30 frames per second. Unfortunately, 1080p also shoots at a maximum of 30 pictures-per-second. The recording quality has already increased significantly compared to other Xiaomi models. Nevertheless, the recorded sound sounds slightly tinny and reaches to others - even if much more expensive - flagship smartphones not yet approached.

Practical test of the front camera

The front camera resolves with 8 megapixels. Also regarding the front camera the Xiaomi Mi6 convinces with a good and detailed recording quality. Videos records the camera in full HD. Due to the wide angle used, it is also possible to bring several people into the picture. In addition, an adjustable beauty filter can be activated, which artificially softens recordings or processes them on-the-fly.

The dual main camera of the Xiaomi Mi6 convinces with a well functioning bokeh effect, a natural color recording and a lossless, 2-fold telephoto zoom. Video recordings are recorded through the 4 OIS axes without wobbling. The front camera is suitable for all sorts of selfies due to its good recording quality.

connectivity

Telephony

In the mobile network, the Xiaomi Mi6 looks good. Although will no LTE band 20 supported, whereby LTE is only limited usable in Germany, I personally feel the limited LTE reception, however, as not too big a disadvantage. In the test had the Xiaomi Mi6 predominantly H + reception, which is perfect for surfing. Also make phone calls with the device fun. The About meeting quality is not objectionable in both directions. Speech is transmitted in a clearly understandable way and noise canceling is filtered very well by the noise-canceling microphone.

Wi-Fi and Bluetooth

Im Wifi The Xiaomi Mi6 is quickly connected by the supported WiFi protocols 802.11a / b / g / n / ac. In addition, the smartphone MU-MIMO is compatible. In the test convinced the smartphone by a high connection range with simultaneous connection stability and high data throughput rate. With Bluetooth 5.0 The latest Bluetooth standard is supported. Unfortunately there are still very few Bluetooth 5.0 devices, which is why only one Bluetooth 4.2 loudspeaker was used in the test. Again, there was no misfire in the connection and transmission.

GPS and sensors

A GPS Compass Fix was found within a few seconds. There were no disconnections while navigating. The signal was kept constant and even between street canyons there were no disturbances. Even inside buildings, the Xiaomi Mi6 proved to be a strong receiver and was able to determine exactly the position up to a few meters.

The sensory equipment amounts to an ambient light sensor, an acceleration sensor, a proximity sensor, a Hall sensor, an e-compass, a barometer and a gyroscope. In addition, the smartphone is equipped with an infrared transmitter, which can be controlled with the Mi Remote App TVs and other devices. The fingerprint scanner is characterized by a high recognition rate and a short unlocking time.

Anyone who can do without LTE Band 20 will receive my very well connected smartphone with good voice quality. Connections to WLAN and Bluetooth are characterized by a high reception range, signal strength and data throughput rate. Precise navigation is also no problem thanks to the well-functioning GPS.

Audio

The Xiaomi Mi6 is the manufacturer's first smartphone, the no 3.5mm jack audio jack has. One might now think that Xiaomi has decided not to make the Mi6 a waterproof smartphone, but the device itself is hardly protected from splashing water. The unprotected USB-C socket, even the smallest splash of water can lead to a direct defect.

Headphones with 3.5mm connection can be connected only via a USB-C adapter, which is included in delivery. Alternatively, there are also USB-C headphones, such as the shortly after the Xiaomi Mi6 published Xiaomi ANC in-ear, These headphones were for the test, so the sound quality could be tested with direct connection via the USB-C socket. Sonically, the Mi6 cuts a fine figure with both the adapter and the direct USB-C connection. The maximum playback volume is convincing, the sound is clear, as well as rich in detail and no noise.

Stereo sound The Xiaomi Mi6 generates via a loudspeaker on the lower case frame, as well as the auricle, which also acts as a loudspeaker. Unlike many other smartphones with single speakers, the Mi6 creates a spatial sound that achieves a pleasant maximum volume and does not appear distorted.

The sound quality via USB-C and the stereo speakers of the Xiaomi Mi6 is not objectionable. The maximum volume is sufficient, as well as the media playback is clear and not distorted.

Accumulator

The smartphone comes with a non-exchangeable 3350 mAh battery fitted. The Qualcomm Snapdragon 835 proved to be extremely economical in the test, resulting in first-class runtimes both on standby and under constant use. In the PC Mark battery benchmark, the device reached a running time of about 10 hours at medium display brightness. For normal use, including occasional phoning, WhatsAppen, surfing and YouTube, one battery charge allowed an average run time of 1 ½ days. The screen-on-time was between 8 and 11 hours, depending on how the smartphone was used.

Unfortunately, the built-in Quick Charge feature is not yet Quick Charge 4, although the processor would be capable of doing so. Instead, the Mi6 uses "Quick Charge 3.0", Thus, the battery is fully charged after 1 ½ hours. The first 50% battery charge is already reached after 35 minutes. Of course, the prerequisite is that the smartphone is connected to a corresponding one Quick Charge Charger charging. Who puts on the supplied charger, comes to the use of an EU adapter not around.

Summary

After testing the Xiaomi Mi6 for over a month, it will continue to accompany me as a Daily Driver. The smartphone offers an excellent price-performance ratio and impresses with its high-quality workmanship, the appealing design and above all the powerful hardware. Everyday performance and display convince all along the line. The camera can not quite keep up with flagship smartphones, however, convinced in view of the price by a decent recording quality, at least in good light conditions. A downer is the missing LTE band 20. In addition, it would have been desirable if Xiaomi had produced by the absence of the 3.5 mm audio jack, the Xiaomi Mi6 as a waterproof smartphone.

Hey, as always a really good review and that suits me well. My mobile has given up the ghost before 2 weeks and I desperately need a new one. I looked at the OP5, the Mi6, Honor 9 and even the Mi5S. Which one would you recommend to me? The 5S is the cheapest, but is that good too? Which of the 4 has the best camera? I do not play games with it, but it should run smoothly. The display is also important to me. I would be glad if you could help me with the selection. You have far more experience than me.

So somehow my Mi6 zips since I installed the new Global. The battery consumption is enormous and the pictures I take with the camera look blurred. Do you have an idea what that should be?
