Following the tests of the display, camera and audio system, specialists of the DxOMark laboratory checked the autonomy of the flagship Xiaomi. Despite fast charging and almost two days of battery life, in the overall rating, the device took only 53rd place.
Xiaomi 12 received a 4500 mAh battery with support for fast wired charging at 67 watts and wireless up to 120 watts. In the laboratory, DxOMark tested the battery of the phone is a complete set of 8 GB of RAM and 128 GB of internal memory. Experts noted the high speed of charging but at the same time the low autonomy of the device.
Of the pros: the smartphone can be charged to 80% using wired charging in just 27 minutes and 21 seconds. Wireless charging is called “excellent” and charges to 80% in 34 minutes and 55 seconds. Despite these advantages, Xiaomi 12 has problems with autonomy: with intensive use, the device works for 29 hours, with moderate use – up to 45 hours. In terms of autonomy, Xiaomi 12 overtook, for example, the Samsung Galaxy S22, but it turned out to be far from the Realme GT 2 Pro.
“Regardless of whether the default settings are set or calibrated, the device has an above-average final autonomy, mainly due to its characteristics that require a lot of power,” the laboratory experts write.
Of the minuses in the laboratory noted problems in streaming music and video, calls and games, poor performance when using GPS navigation, high discharge when playing music and high power consumption when the gadget is fully charged and is still on wireless charging. As a result, the phone’s battery took 53rd place in the global DxOMark rating and the 14th line among premium devices.
