-[* black] The watches' fuel tanks are hidden under the motherboards and nestled in plastic midframes.
- [* icon_note] Thankfully both of them can be removed without any heat—as long as you have a sturdy [product|IF145-002-4|spudger|new_window=true] on hand.
-[* black] The Watch4 Classic 46 mm accommodates a 1.35 Wh (361 mAh @ 4.47 V) battery, while its 40 mm little sister, the Watch4, houses a 0.93 Wh (247 mAh @ 4.47 V) battery.
- [* icon_note] Compared to the Watch3 with 1.3 Wh (340 mAh @ 3.85 V), this isn't much of a change in capacity. With 1.6 Wh the [guide|141415|2021 Mi Watch|stepid=283236|new_window=true] still packs a little bit more power and the [guide|136694|Apple Watch Series 6|stepid=271741|new_window=true] twiddles its thumbs at the bottom of the stack with 1.17 Wh.

+ [* icon_note] Compared to the Watch3 with 1.3 Wh (340 mAh @ 3.85 V), this represents a modest upgrade. With 1.62 Wh, the [guide|141415|2021 Mi Watch|stepid=283236|new_window=true] still packs a bit more power—and the [guide|136694|Apple Watch Series 6 (44 mm)|stepid=271741|new_window=true] twiddles its thumbs at the bottom of the stack with 1.17 Wh.
[* black] We shake the last components out of the midframe and find a [guide|135891|familiar|stepid=270173|new_window=true] vibration motor next to the barometric sensor.
[* black] But the most interesting part is the button flex cable. It not only carries a microphone (''#snore-tracking''), but is equipped with an additional contact plate opposite its connector. This allows the watch to close an electrical circuit through your body for bioelectric impedance analysis.
