Xiaomi’s first wireless headphone charger: how long it takes and how to do it correctly

You've just unpacked Xiaomi's new wireless headphones -- be it Redmi AirDots 3, Xiaomi Buds 4 Pro or any other model -- and you've been faced with the eternal question: How long does it take to charge them for the first time? The answer isn't as obvious as it sounds. Manufacturers rarely give clear guidelines, and battery-pumping myths are confusing. In this article, we'll look at what's really important for first charging and what's outdated stereotypes.

Modern lithium-ion and lithium-polymer batteries used in Xiaomi headphones do not require multiple discharge-charge cycles to activate. However, the first charge still matters — it affects the calibration of the power controller and battery durability. It is not time, but the right sequence of actions and charging conditions. Next, we will tell you how to avoid typical errors and maximize the life of your headphones.

Why First Charge Is Important: Myths and Reality

Many users still follow the advice of the Internet, which was relevant 10-15 years ago for nickel-metal hydride batteries, such as the popular myth that "earphones should be completely discharged and then charged for 12 hours." For modern Xiaomi batteries, this is not only pointless, but harmful.

• 🔋 Lithium-ion batteries don't have a memory effect. They don't need to be trained in full discharge cycles.
• ⚡ Keeping your headphones on just in case charge after 100% reduces battery life.
• ⏳ 12 Charging hours are overkill. Most Xiaomi models charge for 1-2 After a few hours, connecting to the network only heats the battery.

So what's really important when you first charge? Three key things:

1. Use the original cable and adapter (or certified equivalent with 5V/1A or 5V/2A support).
2. Charge at room temperature (15-25°C), avoiding direct sunlight.
3. Do not interrupt the process until 100% (but do not leave the charge for more than 30 minutes after full charging).

How long to charge Xiaomi headphones for the first time: table for popular models

The first charge time depends on the headphone model and the battery capacity. Below is a table with the current data for popular Xiaomi devices (2020-2026). Note: this is a time up to 100% when using the original charger.

If your model is not in the table, look for passport details (usually indicated on the box or in the instructions). For example, for headphones with a case capacity of 400-500 mAh, the first charge time will be 1.5-2 hours. Importantly, Xiaomi often uses fast charging technology (for example, in the Buds 4 Pro), but this does not mean that the first charge should be interrupted prematurely.

⚠️ Note: If the headphones charge longer than the specified time (for example, Redmi AirDots 3 - more than 2 hours), check the cable and adapter. Using uncertified accessories can lead to overheating of the battery and reduce its life.

Step-by-step: how to charge Xiaomi headphones for the first time

To avoid errors, follow this guide. It is universal for all Xiaomi models, but with specific device features (e.g., fast charging).

Check the complete set (cable, case, headphones)

Connect the cable to the original adapter (or certified with 5V/1A-2A support)

Place the headphones in the case and close the lid.

Connect the case to the charger and wait for the start indication (usually a flashing red/orange LED)

Leave to charge until the indicator is full (green or white)

Shut off the network 30 minutes after reaching 100%-->

Some models (such as the Xiaomi Buds 4 Pro) support wireless charging, and if you’re using it for the first time, consider:

• 🔌 The charging area must support the Qi standard (5W higher).
• 📱 Place the case in the center of the site – displacement can lead to slow charging or overheating.
• ⏱ The charging time will increase by 20-30% versus the wired method.

After the first charge, it is recommended to completely discharge the headphones (before automatically turning off) and recharge to 100% again.This will help calibrate the power controller, but you do not need to repeat the procedure regularly.

💡

If the charging indicator is not on, try to clean the contacts of the case and headphones with a dry cotton swab. Often the problem lies in oxidation or contamination of the contacts.

Typical errors in the first charge and their consequences

Even experienced users sometimes make mistakes that shorten battery life, and here are the most common ones and what they threaten:

• 🔥 Left-hand chargers: Cheap cables and adapters can produce unstable voltages, causing the battery to overheat and degrade. 9V/2A (from the smartphone) can damage the headphone power controller, designed for 5V.
• ❄️ Charging at extreme temperatures, if you charge your headphones in the cold (below) +5°C) or in the heat (above) +35°C), the battery capacity may decrease by 20-30% afterward 10-15 cycle.
• 🕒 Interrupting the first charge: If the headphones are turned off to 100%, the power controller may misidentify the actual battery capacity, which will lead to a rapid discharge in the future.
• 🔌 Stay on overnight charging. Once you reach 100%, modern devices turn off power, but the microcontroller remains active, resulting in passive discharge and overheating.

One of the most dangerous mistakes is using headphones during the first charge, which puts additional stress on the battery and can lead to:

• 🔋 Failure of the power controller (earphones will incorrectly display the level of charge).
• 🔥 Local overheating of the battery, which reduces its life.
• ⚡ Incomplete charging, as part of the energy is used to reproduce sound.

⚠️ Note: If after the first charge, Xiaomi headphones discharge for 1-2 (a) the hour (at the time of the declaration) 5-6 The calibration procedure was most likely broken at work hours, in which case a full discharge-charge cycle (discharge before switching off, then charge to the power supply) will help. 100% non-interrupted).

How to extend the battery life after the first charge

The first charge is just the beginning. To make Xiaomi headphones last longer, follow these recommendations:

• 🔄 Avoid full discharges. Optimal battery range — 20-80%. Regular discharges to 0% reduce the battery life.
• 🔌 Don't keep charging constantly. Once you reach 100%, disconnect your headphones from the network. Except if you use them on "constant alert" (e.g., for calls).
• 🌡 Keep it cool. If the headphones lie unused for more than a week, the optimal storage temperature — 10-15°C (for example, in the bottom drawer of the table, not on the windowsill).
• 🔋 Use original accessories. Xiaomi's cables and adapters are designed to provide optimal charging current. Cheap analogues can deliver power surges.

For active noise cancellation (ANC) models like the Xiaomi Buds 4 Pro or FlipBuds Pro, consider that this feature increases battery consumption by 20-30%. If you notice that headphones are running out faster, try:

• 🎧 Shut down. ANC in the settings if it is not needed.
• 📲 Update the firmware through the Mi Home or Xiaomi Earbuds app (sometimes software bugs lead to increased power consumption).

Frequent questions about the first charge of headphones Xiaomi

Conclusion: What is really important when you first charge

To sum up, remember the three main rules for the first charge of Xiaomi headphones:

1.The charging time depends on the model (usually 1-2 hours to 100%), but should not exceed passport values by more than 30 minutes.

2. Use original accessories - this is a guarantee of stable voltage and safety for the battery.

3.Do not interrupt the process until full charge and do not leave on charging for more than 30 minutes after 100%.-->

By following these guidelines, you’ll maximize battery life and avoid typical problems. If your Xiaomi headphones are still running out quickly or don’t hold the charge, check your settings, update your firmware or contact a service center. In most cases, the problem is solvable!
