Xiaomi is expected to launch two new flagship smartphones in the form of Mi MIX 2S and Mi 7 this year. Both the smartphones are expected to arrive with the flagship Qualcomm Snapdragon 845 SoC and will launch either at Mobile World Congress 2018 or later. However, Xiaomi sells more of its budget and mid-range devices than the premium ones and the Chinese company’s next big product in that segment could be the Mi Max 3.
Like the Redmi 5 and Redmi Note 5 series, the Mi Max 3 is also expected to adopt the new thin bezel design and support for a display with 18:9 aspect ratio. The Chinese blog CNMO first detailed the smartphone in December last year and claimed that it will feature a huge 5,500mAh battery in its thin bezel-less design. The smartphone is also said to feature a 7-inch display with 18:9 aspect ratio, dual-camera setup at the rear, and could pack in either a Snapdragon 630 or Snapdragon 660 chipset depending on the model.
Now, XDA Developers have found more information about the device via firmware files, which it claims confirms some of the leaked information and sheds light on the topic. The firmware reveals that Mi Max 3 will launch with the Qualcomm Snapdragon 660 chipset and there might be a Snapdragon 630 variant but the firmware files don’t show any signs of it.
The firmware also confirms that the battery capacity of Mi Max 3 will be 5,500mAh and confirms the use of a 18:9 panel. But these firmware files obtained by XDA Developers do not confirm the size of the display.
The most interesting piece of information comes in the form of support for wireless charging. Xiaomi has not launched a smartphone with wireless charging just yet and it joined the Wireless Power Consortium late last year. The Mi 7 is expected to be Xiaomi’s first smartphone to support Qi wireless charging but by bringing the feature to Mi Max 3, Xiaomi will make it popular in the mid-range segment as well.
XDA reports that within the MIUI Keyguard APK, it discovered strings related to wireless charging and strings that tell whether charging has stopped and if yes, whether it is because of the device’s position from the base of the charger. There is also a help video or graphic made by Xiaomi that shows the user how to place their device right on the wireless charger.
The phone shown in the graphic might not be the final Mi Max 3 and it looks more like the Mi MIX 2 but Xiaomi’s future product lineup might include a broad range of devices with wireless charging support. The firmware files also revealed what sensors Xiaomi plans to use for its device.
The files reveal that the Xiaomi Mi Max 3 will use either an IMX 363 from Sony or a combination of Samsung ISOCELL S5K217 and S5K5E8 dual-camera system. On the front, it will use a single Samsung-made S5K4H7 image sensor. There is also a mention of an iris sensor accompanying the front camera.
The firmware reveals that the sensor used here is the OmniVision 2281 which uses a 1.12-micron pixel size and offer iris recognition for smartphones and tablets. The firmware indicates that Mi Max 3 will run Android 8.1 Oreo and the first API level indicates that the device started with Android 7.1 Nougat. It is possible that the final device will launch with Android Nougat instead.
Other details revealed by the firmware include a dual-SIM card slot, support for two SD cards, an IR blaster, LED light for notifications, support for Qualcomm aptX and aptX HD Bluetooth audio codecs and audio tuned by Dirac. However, there appears to be no NFC.
The new details suggest that the Mi Max 3 will be a major update over the Mi Max 2 in terms of features, and is likely to be officially announced sometime in the second quarter of 2018.
