Foreword: Xiaomi Mi Max 3

"Phablet" refers to smartphones that could go through their oversized display as a tablet. Since 2016 Xiaomi leads under the name "Max" a phablet series, which is particularly popular in Asia.

Design, workmanship and delivery

The Mi Max 3 is guaranteed not a smartphone for small hands. The im Unibody design held and mostly made of metal smartphone is stately 176.15 mm high and 87.4 mm wide, With a Thickness of only 7.99 mm The handheld is relatively narrow. That too Weight is with only 221 g kept pleasantly low.

The smartphone is set up as follows:

The front takes the 6.9 inch large display. This is the display compared to last year Xiaomi Mi Max 2 grown again by 0.46 inches. The housing is not equal. In order to accommodate the larger display, Xiaomi has shrunk the display margins and deleted the capacitive buttons. The operation is instead via virtual display buttons. Features of the front include the front camera with LED flash and a notification LED, but only in white lights.

Due to the unibody design are the housing frame and the back not separated, but made in one piece. The front is offset by about 1 mm to the rest of the housing. The frame edges are rounded and flow smoothly into the back. The case frame includes the left hand the power button and volume rocker. Opposite is the dual SIM slot, which holds two Nano SIM cards or a Nano SIM and a MicroSD memory card. The connectivity of the Xiaomi Mi Max 3 amounts to a USB-C socket and a 3.5 mm jack audio jack. In addition, there is an infrared transmitter on the upper side.

The structure of the back is with the last tested Xiaomi Mi A2 comparable. Top left is the vertically arranged and slightly protruding dual main camera with center LED flash. A circular fingerprint scanner is located in the middle of the upper third of the back. The plastic antenna strips are inconspicuously embedded in the back.

The Mi Max 3 is excellently processed and, despite its size, feels comfortable in the hand. The What's in the box In addition to the smartphone includes a quick charger (5V 3A - 9V 2A - 12V 1.5A), a USB-C cable, a SIM needle and a user manual.

The display of the Xiaomi Mi Max 3 is of the type IPS and solve one Diagonal of 6.9 inches with 2160 x 1080 pixels on. Thus, the display comes on Aspect ratio of 18: 9 and a dot density of 350 DPI.

display measurement

The display measurements made with a colorimeter yielded among other things a maximum luminance of 475 cd / m², Xiaomi itself specifies the display with a luminance of 520 cd / m². The illumination deviates from the middle of the display to the edges of the display by up to 45 cd / m².

The Black value of 0.33 cd / m² As well as the Contrast ratio of 1.430: 1 are appropriate according to the price range. Of the Color and Grayscale presentation is deviated with an average DeltaE of 3.8 and maximum DeltaE of 6.4. Due to the reduced proportion of red and increased blue content, the color temperature is rather cool. In particular, gray scales appear predominantly bluish-gray.

Display in everyday life

In everyday life, the display looks good. The display is extremely sharp despite the huge display diagonal so that individual pixels can not be seen with the naked eye. Outdoors, especially in sunshine, the display is easy to read. Only the slightly reflective display glass can affect readability in direct light. It is also remarkable how much the display brightness can be reduced. Especially in the dark, the display remains pleasantly readable with greatly reduced display brightness.

Also not to complain about is the Viewing angles, Even flat viewing angles can withstand the presentation. The brightness deviation resulting from the display measurement is not noticeable in everyday life.

Display settings and functions

The display settings are comparatively extensive. In addition to the manual and automatic brightness adjustment, there is a night and reading mode that filters blue light components, there are extended color and contrast adjustment options with 3 color profiles, as well as an adjustment to the text size.


The touchscreen recognizes a maximum of 10 simultaneous inputs. The recognition accuracy is good on average. Idiosyncratic Ghost Touches do not occur. The display is protected by an unspecified, hardened protective glass. A special coating reduces fingerprints and increases lubricity.


Qualcomm Snapdragon 636

As well as in the Xiaomi Note 5 Redmire works in the Xiaomi Mi Max 3 Qualcomm Snapdragon 636 System-on-Chip (SoC). The mid-range SoC CPU works with 8 Kryo 260 processor cores clocking up to 1.8 GHz. The graphics unit is an Adreno 509 GPU.

The smartphone is in two memory sizes available. Depending on the model you get one 4GB or 6GB LPDDR4X dual-channel memory and one 64GB or 128GB eMMC5.1 data store, A memory expansion by means of MicroSD memory card is possible, but then you have to do without the second SIM slot.


The benchmark results are inconspicuous and correspond to those of other smartphones with identical features. The AnTuTu benchmark achieves a middle class score of 119.097. Just as appropriate are the memory speeds, Our test copy with 4 + 64GB memory reaches an average of several measurements 5.8 GB / s RAM speed and 210 MB / s read and write speed.

Performance in everyday life

In everyday life, the Xiaomi Mi Max 3 shows no weaknesses. The system is always fluid to use. App start without delay and let the performance in multitasking not noticeably break. Lush memory keeps apps that have already been opened in memory for a long time, making them available on demand. Web pages render the system also swiftly, scrolling mostly without stuttering and animations are displayed fluid.


Although the Mi Max 3 is not a high-end smartphone, it is well suited for the latest mobile games. Graphically challenging games, such as PUBG or Asphalt 9, are fluently playable. For some, however, it is recommended to choose average graphics settings. Although there are no delays in speaking, some cases of image collapse may occur. The temperature reached after 30 minutes PUBG was at the warmest point at 37 ° C. Throttling processor performance does not occur.

User Interface

The smartphone comes with MIUI 9, based on Android 8.1. Since October is one Update to MIUI 10 stable available, but not on Android 9, but continues to build on Android 8.1. System updates and security patches are routinely distributed over-the-air (OTA).

Functionally, MIUI is far removed from Stock Android. Many functions that are otherwise only available through additional apps are already firmly integrated into the system. Among other things, a security center is integrated, with which data that is no longer needed can be cleaned up, which monitors the battery consumption and with which apps can also be password protected. Many of the pre-installed apps come directly from Xiaomi. The main Google Apps, including the Google Play Store are also pre-installed on the smartphone.

Another feature of MIUI is the "Second Space". For example, if you want to separate business and private, Second Space allows you to create independent user accounts. In addition, apps can be duplicated so that multiple user accounts can be used with one app.


The main back camera is identical to the main camera of the Xiaomi Note 5 Redmire, Installed are one 12 Megapixel Samsung S5K2L7 Image sensor with 1.4 μm pixel size and f / 1.9 aperture, as well as one 5 Megapixel Samsung S5K5E8 Sensor with 1.12 μm pixel size, The second sensor is a pure auxiliary sensor that allows the so-called "bokeh effect". The 8 megapixel front camera also comes from Samsung. The image sensor is on Samsung S5K4H7 with an f / 2.0 aperture.

Practical test of the main camera

Photo mode

In direct comparison to Xiaomi Mi Max 2 the recording quality has improved significantly in good as well as in low light conditions. Photographs are color-coordinated very naturally. The subject in focus is sharply focused and details and fine textures are well preserved. Only more distant objects appear a bit out of focus and reduced in detail. Aberration aberrations may be isolated, but are a rarity.

Dynamic range and HDR

The dynamic range is, as so often with smartphone cameras, rather narrow. Even so, the Xiaomi Mi Max 3 copes well with high-contrast scenes and balances bright and dark areas. An automatic HDR mode is available. The mode automatically activates scene-wise, but it often delivers color-distorted and unnatural results.

Bad lighting conditions

The recording quality deteriorates with increasingly poor lighting conditions. Details are lost, colors are slightly distorted and the image noise increases. The deposited in the MIUI camera app HHT (Handheld Twilight) Function should improve the recording quality at night. The emphasis should be on. In the test, there was no difference between activated and deactivated HHT mode.

What can improve the recording quality in the dark is the HDR mode. If you add this in addition, colors are displayed less pale and the image noise is reduced.


There is no lossless telezoom. Instead, one is maximum 8, digital zoom possible. Accordingly, the zoom is limited in terms of recording quality. Even at two times magnification, the enlarged shot is slightly muddy, in particular, fine details are lost.

Bokeh and AI

Very well implemented is the Portrait mode of the Mi Max 3. Especially people are brought to the fore. Complex objects are extracted less cleanly, which can lead to errors in the blurring effect. The AI scene mode was not available at the time of testing and will be fully implemented with MIUI 10.

video mode

With the MIUI Camera App It is possible to record video in 720p, 1080p and 4K. The 4K refresh rate is limited to 30 images-per-second. On 1080p up to 60 pictures per second are possible. The recording quality in video mode comes as close as possible to the photo-recording quality. Video recordings are color well matched. In 1080p recording mode, however, the colors look a bit fuller than in 4K mode. But the level of detail in 4K mode is much higher and the overall picture is sharper. The Autofocus (dual-pixel) works fast and accurate.

A electronic image stabilization (EIS) is available. In 4K recording mode, however, stabilization has no effect. Here it is advisable to switch to the Open Camera App, which stabilizes cleanly on 4K recordings. The Ton is recorded in stereo (bitrate 96 kbit / s) and sounds clear and clean.

Practical test of the front camera

The 8 megapixel front camera produces acceptable photo and video recordings. Some of the shots are heavily overexposed and distorted in color. In addition, with increasingly poorer lighting conditions, an increased image noise is noticeable. After all, there is one Front-LED flashthat illuminates the subject evenly. Focusing is not possible because of the fix focus. Videos are recorded in 1080p at 30 frames per second.

Numerous Beauty Filter pretty artificial selfies shot. In addition to blurring, the MIUI Camera app offers an advanced beauty mode that makes your face look slimmer, eyes enlarged, and skin tones changed.



Both the Chinese and the global model of the Mi Max 3 come with identical mobile phone support. All common in Germany 2G, 3G and 4G mobile bands are available. Here is an overview:

  • mobile: B2, B3, B5, B8
  • CDMA 1X / EVDO: BC0

  • FDD LTE: B1, B3, B4, B5, B7, B8, B20

However, the smartphone is not suitable for worldwide use, as some country-specific bands are missing. LTE is supported on both SIM slots. Volta is available and can be exchanged between the slots. VoWiFi or WiFi Calling is not supported.

There are positives to the reception quality report. The smartphone is very powerful and allows even in mobile phone-poor places, where so many other smartphone hapern, a mobile phone reception that is sufficient for making calls and mobile surfing. The voice quality is good. The earphone clearly reproduces spoken words. Only at full volume does the listener tend to distort slightly. The noise-reducing microphones keep noise very well.

Wi-Fi and Bluetooth

The Mi Max 3 is with a Dual AC WiFi and Bluetooth 5.0 Module equipped. Again, the smartphone is very strong signal. Even two floors away from the router, the reception is so good that surfing the web is never torture. In the Bluetooth network, the smartphone behaves inconspicuously and convinces by a good transmission quality.

GPS and sensors

The smartphone picks up on the position GPS, AGPS, GLONASS and Beidou back. The European navigation system Galileo is not supported. A GPS fix is ​​made quickly and the position is determined to within a few meters. Even inside the building, a GPS fix is ​​possible, although the construction takes a little longer. Navigating is no problem with the Mi Max 3. Whether rural or urban area, the smartphone is sovereign and locates precisely. A well-functioning E-Compass is available.

The sensory equipment includes an ambient light sensor, a proximity sensor, an acceleration sensor, a gyroscope, a Hall sensor, the aforementioned E-compass and an infrared transmitter. With the IR transmitter The smartphone can control TV or Smart Home devices. The matching Mi-Remote App is already preinstalled. Unfortunately, the smartphone comes without NFC therefore.

The back Fingerprint scanner is easy to reach despite the size of the smartphone. The recognition rate is high and the smartphone is unlocked quickly. A "Face Unlock" Function is already integrated into the system, depending on the ROM. The face recognition functioned reliably in the test and could not be outsmarted with a picture.


The Xiaomi Mi Max 3 is capable of one stereo sound to create. For this purpose, the mono speaker acts with the earphone. In terms of volume, the mono speaker trumps the earphones, so that only a limited spatial stereo sound is generated. The sound is dynamic, but as so often the volume is missing. The maximum volume convinced and even at full volume no unpleasant scratching. A 3.5 mm jack is available despite USB-C connection. The playback quality over both ports, there is nothing to complain about.


Not only is the smartphone extremely large, but the battery is getting high Capacity of 5500 mAh (Resized: 5350 mAh). That's enough to reach a runtime of at least 2 days under normal usage. The screen-on-time measured on average display brightness is almost 11 hours. In standby, the smartphone reaches a running time of more than 10 days. Without use, the daily battery consumption is about 7-10%.

Can I also navigate with my phone? Looking for something with a large display that replaces my sat nav. I do not know how it is with these Chinaphones. Whether they are good or not. GPS has it, but there are the card programs on it?


Hello, I have a question that vlt me. someone from you can answer. I'm looking for a smartphone that I can connect via USB-C with a Displayport. Is the USB-C port of the Mi Max 3 able to do this?


Definitely not. Have tried it with several adapters, because I wanted to use my Max 3 for presentations at the university. You can mirror the display via app but it does not work via the USB port.
