As one of the best-selling smartphones in the market, the Xiaomi Mi MIX 2 has made many improvements on its internal design and material. The teardown of the Xiaomi Mi MIX 2 is not difficult. Now, let’s start the teardown on the Xiaomi Mi MIX 2.
Teardown is what we do! Follow us on Facebook for the latest repair news.
The antenna’s number has been increased owing to the enhancement of communication capability. The Xiaomi Mi MIX’s surface is covered with NFC antenna, while the Xiaomi Mi MIX 2’s NFC antenna has been removed to the back case. The LED flash the Xiaomi Mi MIX adopts on the back has been designed on the Mi MIX 2’s main cover. In this way, LED flash’s failure resolute from poor contact can be avoided.
The Xiaomi Mi MIX 2’s connection method to motherboard is different from its predecessor’s because of vibrate earphone. It connects to the motherboard via bridge circuit on the main cover. The metal material the MIX 2’s main cover adopts is thinner than the plastic material MIX features. With such design, the MIX 2 can bring better electrostatic shielding.
Compared with its last generation, the Xiaomi Mi MIX 2 has made some adjustments on motherboard connector’s layout. The main changes include that the MIX 2 has replaced piezoelectric ceramics components with vibrate earphone and liner vibrator has superseded rotor vibrator. Compared with rotor vibrator, the linear vibrator acts with swifter response and creates lower noise. The Mi MIX 2 has cancelled earphone port, which can improve sealing effect.
After remove the back case, the MIX 2’s internal design can be clearly seen. It is obvious that the phone continues the MIX’s design and adopts three-stage layout. It has new design on loudspeaker structure. Its battery doesn’t occupy much space since its motherboard has occupied much.
The MIX 2 has continued the MIX’s design on the back. But it adds double sided tap around the phone not only to avoid the MIX’s loose problem but improve sealing effect. Personally speaking, it will have great improvements both on ergonomics and appearance if the phone’s back adopts curved surface design like the Note series.
The motherboard has low utilization of space on its front part, which continues the MIX’s feature, top part in particular. The component density, as a whole, is low. That’s the reason for two phones’ large motherboard.
The MIX’s utilization on motherboard’s space is a mess, while the MIX 2 has slightly improved on it. Material for cooling on the shielding case is covered with metal cooling paste. The MIX adopts S-shaped thermal silica on the thermal conductive paste, while the MIX 2 uses thermal silica gel. With such change, the MIX 2 has certain improvement on heat dissipation effect.
Here is the whole device without motherboard.
Then remove the battery. The battery is fixed by two easy-to-pull stickers. The sticker is easy to break. After we take the picture, the sticker gets broken, and it drops under the battery, I suggest pull out the sticker slowly at slant 60 degree upward.
The MIX 2’s battery is provided by SCUD. The battery’s capacity is 3,400mAh, while the MIX’s battery capacity is 4,00mAh. The MIX 2’s battery supports 18W fast charging, which is far from reaching the standard that terminal device’ fast charging reaches. After all, current flagships basically sport the battery which supports over 20W fast charging. Of course I refer to Android phones exclude iPhones.
