Full instructions: how to charge the Haylou watch from Xiaomi

Haylou smartwatches and fitness bracelets are popular gadgets from the Xiaomi ecosystem that require regular recharging. However, many users face problems: the device does not charge, the indicator does not burn, or the battery goes down too quickly. In this article, we will analyze all the nuances of charging for Haylou Solar models, LS05, GT1, LS02 and others, including the choice of charger, full charge time and typical errors.

Haylou’s charger connectors are different from classic microUSB or Type-C connectors, using a magnetic suction pin connector, which is convenient but requires care – improper connection can damage the contacts. It is also important to note that some models (e.g. Haylou Solar) are also available. LS05) Support fast charging with the original cable only, and the use of uncertified adapters reduces battery life.

If your watch stops charging or runs out in a few hours, don't rush to bring it to service. 80 percent of the time, it's a simple matter of cleaning contacts, changing cables, or resetting, and then we'll go through every step of the way, from pre-charging to diagnosing faults.

1.Preparing Haylou watches for charging

Before you connect your watch to the charger, follow a few simple steps to avoid contact issues and prolong battery life:

• 🧼 Clean the contacts on the watch and magnetic cable with dry soft cloth (micfibre is fine). Avoid alcohol or wet wipes - they can oxidize metal.
• 🔋 Check the charging cable for damage, bends, bare wires or chipped on a magnet. A damaged cable can shorten and disable the power controller.
• 📱 Turn off Bluetooth (optional, but recommended). While charging, the clock continues to sync data with the phone, which increases the full charge time by 10-15%.
• 🌡️ Allow the watch to cool if it overheats (e.g. after intense exercise) Charging at temperatures above 40°C reduces battery capacity.

And you'll pay special attention to the magnetic connector. GT1 The contacts are asymmetrical -- if the cable is not tightly attracted, flip it over with the other side. The strength of the magnet should hold the cable even when you're sipping.

⚠️ Warning: Do not use abrasive materials (paper sandpaper, metal brushes) to clean contacts, this erases the protective coating and accelerates corrosion.

2.How to properly connect charging to Haylou

The connection process depends on the model of the watch. Let's consider the most popular options:

Models with magnetic cable (LS05, Solar, GT1, GT2)

1. Take the original cable (includes the package) USB-A magnetically).

2. Hold the magnetic connector to the back of the watch – it will automatically “attract” to the contacts.

3. Make sure the charging indicator (usually a red or green LED) catches fire. If not, turn over the cable or check the density of the fit.

4. Connect. USB-power-adapter (5V/1A or 5V/2A) computer.

Models with docking station (LS02, LS01)

This watch is charged through a special docking station with spring contacts:

1. Set the clock in the docking station so that the contacts on the back coincide with the "legs" to the station.

2. Press until you click, which means that the contacts have touched.

3. Connect the docking station to USB-port.

Important: Not all Haylou models are wireless charging compatible. LS05 It only supports wired charging through a magnetic cable, and trying to use Qi will cause you to overheat or not react.

💡

If the charging indicator is not on, try connecting the cable to another one. USB-port or adapter: sometimes the problem is a power supply that is not sufficiently strong (e.g, USB 2.0 on older PCs gives you only 0.5A).

3. Optimal charging conditions

The battery life of Haylou depends not only on the number of charging cycles, but also on the conditions in which the process takes place.

• 🔌 Use the original adapter or certified output analogue 5V/1A or 5V/2A. Charging from powerful adapters (for example, 9V/2A for smartphones) accelerates battery wear.
• 🌡️ Temperature: The ideal temperature for charging — 20–30°C. Pri. <10°C or >40°Chemical processes in the battery slow down, which can lead to malfunctions.
• 📵 Avoid charging 100%. Optimal lithium polymer batteries are 20-80%. Keeping the charge at maximum can reduce battery life by 30 to 40 percent%.
• ⚡ Don’t interrupt charging halfway through the process. If the battery doesn’t stabilize, it can lead to a “memory effect” (although it’s minimal in today’s Li-Po batteries).

Many users are wondering: can you charge Haylou from power bank? Yes, but with reservations:

• Power Bank to support exit 5V/1A or 5V/2A.
• Avoid cheap Chinese models without overload protection.
• Do not charge the watch from the power bank at a lower temperature. +5°C (e.g. in winter outside).

⚠️ Warning: If the Haylou watch is 100% after charging, but quickly discharges to 0%, this is a sign of a malfunction of the power controller or battery wear.

💡

Charging at extreme temperatures (below 0)°C or higher than 45°C) may irrevocably damage the battery. Always check the temperature of the clock before connecting to the network.

4. How long does it take to charge Haylou?

The full charge time depends on the model, battery capacity and power source.

• Haylou Solar LS05 (260 mAh - 1.5-2 hours.
• Haylou GT1/GT2 (180–200 mic) — 1–1.5 hour.
• Haylou LS02 (210 mAh - 1-1.5 hours.

How do you know if your watch is fully charged?

• The indicator on the watch will change color (for example, from red to green).
• In some models (GT1) The screen will show the inscription 100%.
• The magnetic cable can be easily detached (in some models, the magnet weakens after full charging).

If the watch is charging longer than 3 hours, it is a cause for concern.

• 🔌 Weak power supply (e.g., weak power supply, USB-port of the laptop instead of the adapter).
• 🔋 Battery worn out (capacity dropped below 60% of nominal).
• 📱 Background processes (data synchronization, firmware updates).

5.Typical errors when charging Haylou

Even experienced users sometimes make mistakes that cause a clock or battery to break down.

1. Using unoriginal cable Cheap analogues may not match the wiring of contacts or have wires that are too thin, causing overheating.The original cable for Haylou is labeled 5V 1A plug-in.
2. If you just returned from a workout or were caught in the rain, let the watch dry for 30 to 60 minutes.
3. If you leave Haylou with zero charge for a month or more, the battery can go into “deep discharge” and stop holding the charge. The optimal level for storage is 40-60%.
4. Newer versions often fix power management errors. Check for updates in the Haylou Fun or Mi Fit app.

Another common problem is that the watch doesn't turn on after charging, and there are many reasons:

• 🔋 The battery is completely discharged (you need to hold on charging for 10-15 minutes before the indication appears).
• 🔌 Faulty cable or adapter (try another kit).
• 📱 Firmware failure (requires flashing through the PC).

⚠️ Warning: If the clock starts to vibrate and turn off after you're connected to charging, it's a sign of a power controller malfunction. Further charging could cause the device to fail. Immediately disconnect the cable and contact the service.

6.How to extend the life of the Haylou battery

The average battery life of a smartwatch is 2-3 years (or 300-500 charge cycles). To delay battery replacement as much as possible, follow these tips:

• 🔄 Avoid full discharge. Connect the watch to charge at 10-20%.
• ☀️ Don't leave it in the sun. Overheat to 50.°C and above destroy the battery structure.
• 📵 Disable unnecessary functions: Permanent pulsemeter (saves up to 30% charge); notifications from unnecessary applications; screen lighting at maximum brightness.
• 🔋 If you haven't used your watch for more than a week, charge it up to 50% and turn it off.

For models with AMOLED-screen (Haylou Solar) LS05) recommended:

• Reduce the lighting time to 5 seconds.
• Use dark dials (black pixels do not consume energy).
• Turn off the gesture to lift the wrist to turn on.

💡

Haylou Fun has Battery Optimization, turn it on so that the system automatically turns off energy-intensive processes (e.g., background synchronization).

7.What to do if Haylou is not charging?

If the charging indicator does not burn, and the clock does not respond to the cable connection, act according to the algorithm:

1. Check the cable and the adapter, try charging the watch from another source (computer, other adapter) and if the light catches fire, the power supply is a problem.
2. Clean contacts Use a cotton swab dipped in isopropyl alcohol (no more than 70% concentration).
3. Press the power button for 10-15 seconds. If the watch doesn't respond, plug it into charging and hold it for 30 minutes, then try again.
4. Reset the settings in the Settings menu → Reset → Reset all settings. Attention: this will delete all data from the clock!
5. Connect the watch to the Haylou Fun app and check for updates.

If none of these methods worked, the reason could be:

• 🔋 Faulty battery (blown, leakage of electrolyte).
• 🔌 Damaged food boards (for example, after falling or getting moisture).
• 📱 Firmware failure (requires flashing through the PC).

⚠️ Warning: If the watch case is swollen or has a characteristic smell (like acetone), do not try to charge the device! This is a sign of an electrolyte leak from the battery. Immediately stop using and dispose of the watch (lithium polymer batteries in this state can ignite).

💡

If the Haylou watch is not charged or turned on, but when connected to a PC is identified as an unknown device, the problem is likely to be the firmware, in which case flashing through the MiFlash or Haylou Tool utility will help.
