What is the basic information about the battery of the Redmi Watch 4? How to charge?

For your reference, here are some details about the battery of the Redmi Watch 4:
1. It takes about 1.5 hours to fully charge the watch. The battery life can reach 20 days or more in typical usage scenarios, the battery life in typical AOD mode usage scenarios can reach 10 days or more, and the long battery life mode can last up to 30 days or more;
2. The battery capacity of the watch is 470mAh. It comes standard with a dedicated magnetic USB charging base and a 50cm long power cord;
3. To charge the watch, place it on the charging stand so that the charging contacts on the back of the watch fully fit the metal contacts on the charging stand. Connect the other end of the charging base to the USB-A charger (output voltage is 5V, output current ≥1A);
4. Some rechargeable batteries have a low-current protection mechanism. When they are almost fully charged, the charging current is very small, and the rechargeable battery self-protection causes power outage. We recommend you to replace the 5V1A adapter for charging;
5. If there is a protective film on the back of the watch, you need to tear it off before charging.
Note:
1. If the watch cannot be turned on after being left for a long time, it will need to be recharged for about 1 minute before the charging icon be displayed before using it again;
2. Please wipe the charging contacts of the watch clean before charging to avoid sweat or moisture residue;
3. Wearable devices need to be charged with a standard charging cable. Using a non-standard charging cable is easy to cause the device to burn. (If you lose the charging cable, you can purchase it on the official website or contact customer service to purchase it.)
