What Xiaomi bracelet models exist and how they differ

Before you charge a device, it’s important to know which model you’re holding, which is what your charging cable is, how you charge it, how you’re charging it, and even where you’re hanging your contacts. Xiaomi has released more than 10 fitness bracelets, but the following are on the market in 2026:

  • πŸ”Ή Mi Band 4 (2019) – the first model with color AMOLED-display, charging through a tweezer connector.
  • πŸ”Ή Mi Band 5 (2020) – improved screen, magnetic charging, support NFC version NFC.
  • πŸ”Ή Mi Band 6 (2021) – larger display (1.56) and fast charging (up to 100% in 2 hours).
  • πŸ”Ή Xiaomi Smart Band 7/7 Pro (2022) β€” Always-On Display, improved sensors, charging through USB-C (pro-version).
  • πŸ”Ή Xiaomi Smart Band 8/8 Pro (2023) β€” full-fledged smart bracelet GPS, microphone and speaker (pro), magnetic charging.

The main difference in charging is the type of connector:

  • πŸ”Œ The pince connector is on the Mi Band 4 and some early versions, and requires a neat connection, because the contacts are easy to bend.
  • 🧲 Magnetic charging – starting with the Mi Band 5. The cable is attracted to the bracelet automatically, which simplifies the process.
  • πŸ”‹ USB-C β€” Smart Band 7 Pro and 8 Pro: Allows you to charge the bracelet from any USB-C cable.

If you are not sure about the model, look at the box or check in the Mi Fitness/Zepp Life app under Device β†’ About the bracelet.

Step-by-step: how to charge the Xiaomi bracelet

The charging process is simple, but many users make mistakes that lead to slow charging or even breakage.

  1. Unplug the strap. Most models (except the Smart Band 7/8 Pro) require the capsule to be removed from the bracelet. To do this, pull the strap away from the body until the click. The Mi Band 4 has the strap removed by an up-and-side motion.
  2. Connect the charging cable. For the Mi Band 4: gently insert the capsule into the charging tweezers so that the contacts match. Don't make any effort! For the Mi Band 5/6 and Smart Band 7/8: attach the capsule to the magnetic connector - it will attract automatically. For the Smart Band 7 Pro/8 Pro: connect the USB-C cable directly to the bracelet (remesh not required).

Connect the cable to the power source.

Do not use fast charging.

Wait for full charge.

1.5 hours to 2 hours

If the bracelet does not respond to the cable connection, check:

  • πŸ”Œ Clean contacts (wipe them with a dry cotton swab).
  • πŸ”‹ Correction of the cable (try another one) USB-port).

Please note:

  • ⚑ The first charge after purchase can take 10-15 minutes longer – this is normal.
  • πŸ”‹ If the bracelet is discharged to 0%, the first 5-10 minutes of the charging indicator may not appear.
  • πŸ“‰ Charging from powerful adapters (18W+) will not speed up the process - the bracelet controller limits the current.

⚠️ Note: If the Xiaomi bracelet is charging for longer than 4 hours and does not gain charge, this may indicate a malfunction of the battery or power controller.

Optimal charge level: how to extend the life of the battery

Many users mistakenly believe that the bracelet should be charged to 100% and discharged to 0%. In fact, the lithium polymer batteries used in the Mi Band degrade faster in such extreme conditions. Studies show that the optimal charge range for maximum life is between 20% and 80%.

Here are some tips on how to extend the life of a battery:

  • πŸ”‹ Do not hold the bracelet 100% for a long time (for example, all night%.
  • πŸ“‰ Avoid deep discharge (below 10%) and recharge the bracelet when the charge drops to 20-30%.
  • 🌑️ Do not charge the device at high temperatures (above 35).Β°C) or in direct sun.
  • πŸ”Œ Use only original cables or certified analogues. Cheap cables can damage the power controller.

The average battery life in the Mi Band is about 300-500 full charge cycles. If you follow the recommendations above, the battery will last longer, and after 2-3 years its capacity will not drop critically.

If you don’t use the bracelet for a long time (for example, during a vacation), store it with a charge of about 50% in a cool place.

What to do if Xiaomi bracelet is not charged

If the bracelet doesn't show the charging indicator after you've connected the cable, don't panic. 80 percent of the time, it's self-solving. Here's the diagnostic algorithm.

  1. Check the cable and the adapter. Try another one. USB-port or charger, inspect the cable for damage (bending, bare wires).
  2. Clean the contacts. Wipe the contacts on the bracelet and cable with a dry cotton swab (do not use alcohol or wet wipes!). If the contacts are oxidized (green coating appears), gently clean them with a swallow.
  3. Reset the bracelet. Connect the bracelet to charging and hold the button (touch or physical) for 10-15 seconds. If the screen doesn't respond, try resetting the settings through the Mi Fitness app (Device β†’ Reset).
