How to charge Xiaomi Mi Band 3: step-by-step instructions

Owners of the popular activity tracker often face a situation where the screen goes out and the vibration stops responding to notifications. Xiaomi Mi Band 3 is known for its autonomy, but even the most capacious battery requires energy replenishment over time. The process of recovery in this model has its own unique features that distinguish it from newer versions of fitness bracelets.

The design feature is that you need to remove the tracker module from the silicone strap to connect to the power source, and this is a solution that engineers have made it waterproof, but sometimes it's a challenge for beginners. If you're picking up this gadget for the first time, it's important to carefully study the procedure so that you don't damage the fragile parts of the case.

In this article, we will discuss all the steps of the procedure, consider possible contact problems and answer frequently asked questions. Proper battery maintenance will extend the life of your device and ensure the stable operation of all health monitoring functions.

Design and preparation

Before you start to manipulate, you have to understand that charging is not going to go through the entire bracelet, but through a separate capsule module, and inside the silicone tape, there's an oval tracker, which is the brain of the device, and that's the part that we have to extract to access the contact pad.

To do this, you'll need the original cable that came with the device, a short plaque with two metal pins at one end and a USB-A connector at the other, and using third-party or damaged cables can lead to oxidation of the contacts or insufficient current.

โš ๏ธ Warning: Do not try to charge the device without removing the capsule from the strap. Direct connection to the silicone is impossible and will only damage the accessory.

Make sure your hands are dry and clean. Fatty footprints or moisture can create additional resistance on the contacts, leading to intermittent charging. It is also recommended to wipe the tracker itself with a soft dry cloth before mounting into the charger.

Extraction of the tracker module

The most difficult step for many users is to carefully remove the oval capsule from the elastic bed of the strap. Silicone tightly wraps the module to ensure waterproofing according to the 5 ATM standard, so you will have to apply some effort.

Turn the bracelet down, and on the inside of the strap, you'll see an oval recess that the tracker is placed in, and you'll press your thumb on the convex part of the capsule on the back side, while pushing it outwards.

  • ๐Ÿ“Œ Place the bracelet on a solid surface for a stop.
  • ๐Ÿ“Œ Press the center of the capsule with your thumb until a characteristic click or shift.
  • ๐Ÿ“Œ Carefully tuck the edge of the module with a nail or plastic spatula.
  • ๐Ÿ“Œ Remove the tracker, trying not to scratch the screen on the edge of silicone.

If the module is very tight, you can stretch the strap slightly with your fingers to warm up the silicone and make it more elastic, and the main thing is to act without fanaticism, so as not to damage the thin walls of the landing site.

Process of connection to the power source

After successfully removing the module, notice the bottom of the module, where there are two golden contacts that should perfectly match the response pins on the charging cable, and polarity is irrelevant, because the contacts are symmetrical, but the correct positioning is necessary.

Put the tracker in the groove of the charging plae to the end. You should feel a slight resistance of the magnets or just a tight fit. If the module dangles or falls out with a light shaking, the connection is not established, and the current will not be transmitted.

โš ๏ธ Warning: Make sure there are no villi, dust or oxides between the contacts.The mud is a dielectric and blocks the passage of electrical current.

Connect the free end of the cable to any 5 Volt power source, which can be a computer port, laptop port or a standard network adapter from a smartphone. Use of powerful Quick Charge units is not recommended, as the power controller may not correctly identify the device.

If the bracelet has been unloaded for a long time, the indicator may not immediately light up. Leave it on charging for 10-15 minutes before panicking.

Status indication and charging time

You can tell that the process has started, you can tell from the monitor screen, and when you connect it should vibrate briefly, and the battery icon will appear on the display. If the screen remains black, check the density of the contacts again.

In normal operation, the full recovery cycle takes 1 to 2 hours, depending on the degree of discharge and battery condition, and after full charging, the battery icon will change, and the vibration will notify the end of the process.

Possible problems and ways to solve them

Sometimes users are faced with a situation where the device refuses to charge, most often the reason lies in the oxidation of the contact sites, sweat and moisture, getting under the strap, create an aggressive environment that over time covers the contacts with a thin film of oxide.

To solve this problem, take a cotton swab, lightly moisten it in alcohol or a special contact cleaner, and gently wipe the gold pads on the tracker and the cable pins. After drying, try to connect the device again.

If the light flashes, it may indicate a critical discharge of the lithium polymer battery, in which case the current jolt may not pass immediately, and leave the device connected to the power source for 30-40 minutes, even if the screen does not respond.

What to do if the bracelet is warm?
If the case gets noticeably hot during charging, immediately disable the device, which may indicate a battery failure or short circuit inside the module.

Recommendations for extending battery life

The battery in the Mi Band 3 has a limited number of recharge cycles. To maximize the life of the device, try not to bring the charge to full zero. The optimal thing to do is to put the bracelet on charge when there is 15-20% of power left.

Also worth considering is the power consumption effects of functions: constant pulse monitoring, frequent notifications and high screen brightness significantly speed up the discharge, and setting these parameters in the Mi Fit app will help increase the intervals between charges.

  • ๐Ÿ”‹ Disable unnecessary notifications from apps.
  • ๐Ÿ”‹ Reduce the brightness of the screen in low light conditions.
  • ๐Ÿ”‹ Use Do Not Disturb at Night to Save Energy.

It is recommended to store the device at a charge of about 50-60% if you plan to not use it for a long time.A fully discharged battery during prolonged storage can degrade and stop holding the charge.

Regularly cleaning contacts and avoiding deep discharge are key factors in the long service of your fitness tracker.

Can I charge Mi Band 3 from Power Bank?
The external power bank is a great power source, especially in field conditions, the main thing is that it produces standard 5V. Power models with automatic detection of low currents may not "see" the bracelet and start charging.
Why does the bracelet charge so slowly?
Slow charging is usually caused by poor contact, long or poor quality use. USB-cable, or by connecting to a low-current port (e.g, USB 2.0 on an old computer, and the speed drops at low ambient temperatures.
Is it dangerous to leave the bracelet on charge at night?
Modern power controllers protect the battery from overcharging, but leaving the device unattended for a long time is still not recommended. This can lead to overheating in the event of a malfunction of the battery.
What to do if the contacts on the bracelet rot?
If the gold coating has worn off or the contacts have been severely corroded, it is difficult to restore them, you can try to clean the surface with a gently eraser or alcohol, but in most cases you will need to replace the tracker module or the entire device.
