560mAh lithium-ion battery is fixed to the motherboard, and the battery information is printed on the surface of the conductive cloth.
The battery and motherboard are fixed by transparent double-sided gel. Double-sided adhesive is located at a large area of heat-dissipating copper foil on the motherboard and the top of the motherboard. A graphite sticker is attached to the main board shield below the hot copper foil.
The box is fixed to the back cover by the snap, the crown button and the side key button and the linear motor are fixed on the box.

The back surface of the speaker adapter is black, and there is a conductive bubble in front.
The bottom heart rate plate is fixed using plastic thermal technology. The soft plate is fixed around the housing by double-sided adhesive.
The heart rate sensor has a protective silicone sleeve. The back cover has four magnets for wireless charging.
The heart rate plate is attached to four conductive bubbles, and the back side uses a large-area conductive cloth.
The dismantling is over, let's review the overall configuration information.
