How to Charge Xiaomi Mi Smart Band 4C
Incorrect charging is the most common reason why the bracelet doesn't turn on. Unlike smartphones, the Mi Band 4C doesn't have a charging indicator on the case, so users often wonder if it's going on. Here's how to do it right:

It takes about 1-2 hours to charge, and to see if it's going on, look at the indicator on the screen: when you connect to the power, you should have a battery icon. If you don't have one, check the density of the contacts or try another. USB-port.
