| [* black] The battery removal requires another tool and with a bit of prying it comes off easily. It’s good to see that a common repair got prioritized instead of soldering the battery to the motherboard. | |
| [* black] The battery is a 1.62 Wh (420 mAh) Li-Ion block which charges wirelessly. | |
| [* icon_note] Xiaomi claims that this little cell powers the watch for 16 days straight or 50 hours during sports. For reference: [guide|136694|Apple Watch Series 6|stepid=271741|new_window=true]: 1.17 Wh, [guide|135891|Samsung Galaxy Watch 3|stepid=270168|new_window=true]: 1.3 Wh, [guide|124018|Huawei Watch GT|stepid=239797|new_window=true]: 1.6 Wh | |
| [* black] Besides the battery the bottom part of the watch case bares a cable assembly which holds a tiny vibration motor, the heart rate and Sp02 sensor array and a barometric sensor and a MEMS Microphone. | |
| [* icon_note] This cable assembly is not removable because of small plastic rivets. You can cut them off like we did however the only possibility after doing this is to glue the cable down in order to hold it in place. Not an ideal solution for replacements. | |
