Mi Band 3 Teardown
Internal Photos​

In addition to the previously posted news about Mi Band 3 FCC Certification, I would like to add photos of disassembled Xiaomi device (Thanks to FCC).

Furthermore, it seems that this is a global version of smart band, and not the one that is being sold now. Enjoy photos and don't try to disassemble your gadget unless you are sure that you utterly need it.

​

As you can see teardown images confirm that Mi Band 3 contains 110 mAh battery.
