Xiaomi Earbuds wireless headphones have become an integral part of the daily lives of millions of users, but the question of their autonomy remains one of the most pressing: how long does it take to fully charge the case and the headphones themselves? Why does one model charge in 30 minutes and another in 2 hours? The answers to these questions depend on the specific model, the type of charger and even the ambient temperature.
In this article, we will take a detailed look at charging times for all current Xiaomi Earbuds (2023-2026), including the flagship Buds 4 Pro, Buds 4 series and budget options. You will learn how to speed up the charging process, what factors slow it down, and what to do if the headphones stopped charging.
How much are the headphones Xiaomi Earbuds: comparison of models
The charging time of Xiaomi headphones varies depending on the model, battery capacity and supported technologies. For example, the flagship Xiaomi Buds 4 Pro with support for fast charging can recover 50% of the charge in 15 minutes, while the budget Redmi Buds 4 Lite will require at least 40 minutes.
- π Xiaomi Buds 4 Pro β 1 hour (earphones) / 1.5 hours (case)
- π Xiaomi Buds 4 β 1.2 hours (earphones) / 2 hours (case)
- π Xiaomi Buds 3T Pro β 1.5 hours (earphones) / 2.5 hours (case)
- π Redmi Buds 4 Pro β 1 hour (headphones) / 1.8 hours (case)
- π Redmi Buds 4 Active β 1.5 hours (headphones) / 2.2 hours (case)
- π Redmi Buds 4 Lite β 2 hours (headphones / 3 hours)
Note that this is the time to charge from the original cable with an adapter of at least 5W. Using uncertified chargers can increase charging time by 30-50%. It is also important to consider that the first 80% of charge accumulates faster, and the last 20% can take up to half the total time - this is due to the protection of lithium polymer batteries from overheating.
Factors affecting charging speed
Even if you use the original charger, the charging time of Xiaomi Earbuds may differ from the manufacturerβs stated, and several key factors influence this process:
- Charger type: Quick Charge 3.0/4.0 or USB-PD adapters reduce charging times by 20-40%, for example, charging a Buds 4 Pro from an 18W adapter will take 45 minutes instead of 1 hour.
- Ambient temperature: The optimal range is from +10Β°C to +35Β°C. At temperatures below +5Β°C, lithium polymer batteries charge 2-3 times slower.
- Battery status: After 300-500 charging cycles, the battery capacity decreases by 15-20%, which increases the charging time.
- Using headphones while charging, if you listen to music while the headphones are in the case, the charging process slows down by 30-50%.
Also worth considering is the quality of the cable: cheap thin-vein cables may not deliver the stated current strength, which leads to an increase in charging time, for example, a cable with a resistance above 0.5 ohms will reduce charging power by 10-15%.

To check the actual charging power, use the Ampere (Android) or Battery Life (iOS) app, which will show the current charging current in milliamperes (mA).
How to speed up charging Xiaomi Earbuds: proven ways
If you need to charge your headphones quickly before leaving, use these tips:
βοΈ Quick charging Xiaomi Earbuds
One of the most effective ways to do this is to turn off the Bluetooth function on your smartphone while you're charging, because the headphones continue to use energy to keep the connection going, even in the case, and you can also use the airplane mode on your phone if the headphones are connected.
For models with fast charging support (for example, Buds 4 Pro or Redmi Buds 4 Pro) it is recommended to use adapters with a power of at least 18W. In this case, 10 minutes of charging will give up to 2 hours of battery life. And if you need to charge the case as quickly as possible, use wired charging instead of wireless - it is 20-30% more efficient.
What to do if the headphones are not charged?
Table: charging time and autonomy Xiaomi Earbuds
| Model | Headphone charging time | Case charging time | Autonomy (headphones) | Autonomy (with case) |
|---|---|---|---|---|
| Xiaomi Buds 4 Pro | 1 hour | 1.5 hours | 6 hours | 30 hours. |
| Xiaomi Buds 4 | 1.2 hours | 2 hours | 5 hours | 25 hours. |
| Redmi Buds 4 Pro | 1 hour | 1.8 hours | 6 hours | 28 hours. |
| Redmi Buds 4 Active | 1.5 hours | 2.2 hours | 5 hours | 20 hours. |
| Redmi Buds 4 Lite | 2 hours | 3 hours | 4 hours | 16 hours. |
The data in the table is for new devices with original accessories. Over time, autonomy can decrease due to battery degradation. For example, after a year of active use, Xiaomi Buds 4 Pro can last on a single charge not 6, but 4.5-5 hours.
β οΈ Note: If your headphones are over 50 percent charging time, it may indicate a battery or power controller malfunction.
Frequent charging problems and their solutions
Xiaomi Earbuds users often face charging problems, and consider the most common ones and how to fix them:
- π Headphones don't charge in the case, it could be a contact contamination or a case malfunction, try to clean the contacts with alcohol and reload the case (hold the 10 seconds button).
- π The case is not charged by the cable. Check the cable and adapter, and also try to connect the case to another power source (for example, to the power supply). USB-port).
- β‘ Slow charging: Make sure you use the original cable and adapter with a power of at least 5W. Also check the ambient temperature.
- π± The headphones are running out of the case, and this may be due to an active Bluetooth connection, so disconnect the headphones from your phone before you put them in the case.
If neither of these methods worked, there may be a problem with the software. Update the headphone firmware through the official Xiaomi Earbuds or Mi Home app.
- Put the headphones on the phone.
- Open the application and go to the Device Settings β Software Update.
- If an update is available, follow the instructions on the screen.
β οΈ Warning: Do not interrupt the firmware update process! This may cause the headphones to fail. If the update is suspended, wait until the battery is discharged (about 12 hours), then try again.
How to extend the battery life of Xiaomi Earbuds
The lithium polymer batteries used in Xiaomi Earbuds have a limited lifespan β typically 300-500 charge cycles β but with proper care, this lifespan can be extended by 20-30%.
- π Avoid full discharge of headphones. It is optimal to charge them when the charge drops to the lower end. 20-30%.
- βοΈ Do not leave your headphones on charge in direct sunlight or in a hot room (above). +40Β°C).
- π Use only original or certified cables and adapters.
- π΅ If you donβt use headphones for a long time, store them with a charge. 40-60% cool-place.
It is also worth calibrating the battery regularly: once every 2-3 months, completely discharge the headphones (before turning off), and then charge to 100% without interruptions, which will help the power controller to determine the level of charge more accurately.
