Hello YouTube this is a Xiaomi Mi Band fitness tracker and this is the charger it stopped charging recently because I used it a lot while showering all the soap and oil got in between the two connectors the connectors on the device and the connectors on the charger to fix it, we need some water & Q-Tip I’m going to dip one end of the Q-Tip in water and keep the other end dry once it’s wet, I’m going to thoroughly clean the two connectors and I’m going to push it as hard as I can don’t worry, they’re not going to break. It’s a solid device. Once it’s clean, I’m going to clean the two pins on the charger. Make sure they are thoroughly cleaned. Now use the dry end of the Q-Tip to remove the water. use the same dry end to clean the water from the fitness tracker try not to touch the pins with your finger because that can leave oil or dirt on it. Once it’s clean, it’s time to test it. We connect and go all the way in. There shouldn’t be any empty space between the Band and the charger pins. Let’s test it. As you can see, the Band is charging. When you see 3 solid lights, that means it’s done charging. Please press the Like button if this was helpful.
