In this article, we will examine all the nuances of charging the Mi Band 1 – from choosing the original cable to extending the battery life.

The peculiarity of this model is that it uses a unique charging connector that is not compatible with newer versions of the bracelets, and because of the age of the device, many people face wear and tear of the contacts or oxidation of the connector. We'll tell you how to avoid common mistakes, which chargers are suitable, and what to do if the bracelet stops charging, and how to extend the life of the battery. 30-50% with simple techniques that are not written in the official instructions.

1.What is the right charger for Xiaomi Mi Band 1?

The main problem with charging the Mi Band 1 is finding a compatible cable. Unlike the newer models (starting with the Mi Band 2), the first bracelet uses a proprietary five-pin connector that is not compatible with USB-Type-C or Micro-USB. The original charger came with a bundle, but over the years many have lost or broken it.

There are several options today:

• 🔌 Xiaomi's original cable is the most reliable, but it's hard to find on sale.

If you are buying a non-original cable, pay attention to:

• 🔍 Number of contacts: 5 (many fakes have 4 or 3).
• 📏 The size of the connector - it should fit tightly into the socket of the bracelet without backlash.
• 🔌 Type of connection to the power source - it is better to choose options with USB-A, Mi Band 1 does not support fast charging.

⚠️ Note: Do not use chargers from other Mi Band models (e.g. Mi Band) 2/3/4) — They have a different connector and can damage the contacts of the bracelet.

2. Step-by-step instructions: how to charge Xiaomi Mi Band 1

The charging process seems simple, but many users make mistakes that lead to a breakdown.

1. Take the bracelet capsule out of the silicone strap carefully, and pull it to the side where the charging connector is.
2. Clear the contacts. Over time, dust or oxidation accumulates on the metal contacts of the bracelet and charger, wipe them with an alcohol napkin or a cotton swab soaked in isopropyl alcohol.
3. Connect the charger. Insert the cable connector into the bracelet socket before you click. Make sure the contacts match -- if the cable is inserted curved, charging won't start.
4. Connect to the power source. Use it. USB-port (5V/0.5A) Or a power adapter with similar parameters. 1 does not support fast charging, so powerful power supplies (such as from smartphones) can shorten battery life.
5. Wait until you're fully charged. The charge indicator (blinking battery) will appear on the bracelet screen. The full cycle takes 1.5-2 hours.

If the bracelet does not respond to the charging connection:

• 🔄 Try turning the connector over (sometimes the contacts don't match the first time).
• 🔌 Connect the cable to another USB-port.
• 🔋 Check if the cable is damaged (check for overburdens or melts).

3.How long does the Xiaomi Mi Band 1 charge?

Charging time depends on several factors: battery condition, cable quality and power source. The table below shows the average values:

If the bracelet is charged for more than 4 hours, this may indicate:

• 🔋 Battery wear – Capacity falls after 300–500 charging cycles.
• 🔌 Bad contact – check if the pins in the connector are bent.
• 📉 Power Controller Failure – Requires Repair.

⚠️ Warning: If the bracelet is heated during charging (more than 40)°C, immediately disable it.This is a sign of a malfunction of the battery or controller, which may cause the battery to bloat.

💡

To speed up charging, warm up the bracelet in your hands for 5-10 minutes before connecting - this activates the chemical processes in the battery, especially if it has been discharged for a long time.

4.How to check the battery level?

The Xiaomi Mi Band 1 doesn’t have a built-in percentage charge indicator, but there are a few ways to assess battery health:

Method 1: On the indicator on the screen

• 🔋 Full charge – battery icon full, no flashing.
• ⚡ Charging is coming - the battery icon flashes.
• 🚨 Low charge (less than 10%) – an empty battery with an exclamation mark appears on the screen.

Method 2: Through the Mi Fit application

1. Open the Mi Fit app on your smartphone.
2. Go to the Profile section → Mi Band 1.
3. Click on the bracelet icon – if the battery is discharged, a notification will appear.

Method 3: By the behavior of the bracelet

• 📵 Disconnected when synchronized - a sign of a discharge below 5%.
• ⏰ The clock is knocked down - the battery is almost dead.
• 🔄 Self-resetting – critical level of charge.

If the bracelet does not show a charging indicator when connected to USB, try:

• 🔌 Connect to another port or adapter.
• 🔄 Reset the bracelet (press the touch button for 10 seconds).
• 🧹 Clearing the contact (see section 2).

5. The bracelet is discharged to zero and does not turn on - how to resuscitate?

If the Mi Band 1 is completely discharged and does not respond to charging, do not rush to throw it away. In 80% of cases, the battery can be "waked up" using the following methods:

Method 1: "Acceleration" of the battery

1. Connect the bracelet to charging for 10-15 minutes.
2. Turn off and reconnect the cable.
3. Repeat the process 3-5 times, sometimes enough to wake up the power controller.

Method 2: Direct power (for advanced users)

• 🔧 Disassemble the bracelet (gently tuck the lid with a plastic card).
• 🔋 Find the battery contacts (usually) + and - marked on the board).
• 📌 Connect them for 1-2 seconds power source 3.7V (For example, from another Li-Po battery).
• 🔄 Then, connect the original charging.

Method 3: Warming up

If the battery was long dead, its electrolyte could crystallize. Put the bracelet (without strap) on the battery from the smartphone for 10-15 minutes to warm up slightly. Then try charging.

⚠️ Warning: Do not use a hair dryer, microwave or open fire to warm up! overheating above 60°C can cause the battery to swell or ignite.

If none of the methods worked, it was likely a deep discharge and the battery needed to be replaced: 3.7V 45mAh) tool-wield.

💡

If the bracelet does not turn on after discharging, first try to "overclock" the battery with multiple connections to charge. Only if this does not help - proceed to disassemble or replace the battery.

6.How to extend the life of the Xiaomi Mi Band 1 battery?

The average battery life of the Mi Band 1 is 2-3 years when used actively, but with a few tricks, you can increase this period by 30-50%:

Operational tips:

• 🔋 Avoid full discharge. Recharge the bracelet at 20 to 30 percent. Deep discharges reduce the life of Li-Po batteries.
• ⚡ Don't use fast charging. Adapters with more current 0.5A accelerate degradation.
• 🌡️ Store at room temperature. Heat (above 35)°C) and cold (below 0)°C) damages the battery.
