Charging time wireless headphones Xiaomi: what depends on and how to check
Xiaomiβs wireless headphones have become an integral part of everyday life, from listening to music to calls and podcasts. But even the most advanced models require regular recharging. Charging time depends on the model, the type of charger and battery status. For example, the Xiaomi Buds 4 Pro with support for fast charging recovers 50% of charge in 15 minutes, while the budget Redmi Buds 3 Lite can charge up to 2 hours.
In this article, we will discuss:
- π Exact charging times for popular models (from Mi True Wireless Earbuds Basic to Buds 5 Pro)
- β‘ Factors Affecting Speed: From Power Supply to Temperature
- π οΈ How to check the charge level of the case and headphones (including without a smartphone)
- β οΈ Mistakes that shorten battery life 30-40%
If your headphones charge longer than usual or discharge quickly, there is an FAQ with solutions at the end of the article.
Charging time by model: comparison table
Xiaomi produces dozens of models of wireless headphones, and their charging time can vary by 2-3 times. Below are the current data for popular lines (2022-2026). All values are given for full charging case + headphones from discharged state (0%) to 100% using the original cable and power supply 5V/1A.
| Model | Case charging time | Time to charge headphones in the case | Type of connector | Support for fast charging |
|---|---|---|---|---|
| Xiaomi Buds 5 Pro | 1 hour 20 minutes | 1 hour (up to 100%) | USB-C | Yes (50% in 10 minutes) |
| Xiaomi Buds 4 Pro | 1 hour 30 minutes | 1 hour 15 minutes | USB-C | Yes (50% in 15 minutes) |
| Redmi Buds 5 | 1 hour 40 minutes | 1 hour 20 minutes | USB-C | No. |
| Redmi Buds 4 Lite | 2 hours | 1 hour 50 minutes | USB-C | No. |
| Mi True Wireless Earbuds Basic 2 | 2 hours 10 minutes | 2 hours | Micro-USB | No. |
Important: Fast-charging models (such as the Buds 5 Pro) can recover up to 3 hours of playback in 5-10 minutes of charging, which is important if you need to recharge your headphones before you go out.
The data in the table is relevant for new devices. If your headphones charge for 30% or more longer, this is a sign of battery wear (for more details in the error section).
What the charging speed depends on: 5 key factors
Even one model can have different charging times, and let's look at the main reasons:
- Power and cable: The original 5V/1A adapter charges the headphones optimally. If you use a smartphone unit (e.g., 18W), the case can heat up and charge time will be reduced by 10-15%. But: for models without fast charging (e.g., Redmi Buds 3 Lite), the powerful unit will not give you any increase in speed.
- Ambient temperature: Lithium polymer batteries charge more slowly at temperatures below +10Β°C or above +35Β°C, Optimal range: +15... +25Β°C.
- Battery status: After 300 to 500 charging cycles, battery capacity decreases by 20 to 30 percent, and charging time increases. You can check wear in the Mi Fitness app (for some models).
- Use while charging: If the headphones are connected to the phone and play sound, they will charge 20-40% slower.
- USB-C models (such as Buds 5 Pro) charge faster than Micro-USB (Mi True Wireless Earbuds Basic 2).
πΉ Tip: If the case doesn't charge for a long time, try cleaning the connector of dust and dirt with a wooden toothpick. In 40% of cases, the problem is solved by this method.
π‘
For models with wireless charging (for example, Xiaomi Air 2 Pro) use charging stations with a capacity of at least 5W. Weak wireless charging can increase charging time by 1.5-2 times.
How to check the charge level of the case and headphones
There are several ways to find out the current charge of the headphones and the case.
1. via the Mi Fitness app (for most models)
- π± Open the application and connect the headphones to the smartphone.
- π Go to the Devices section β [The name of your model].
- π On the main screen will display the charge level of the case and each headphone separately.
2. Through notification on a smartphone
When you connect your headphones to Xiaomi, Redmi or POCO, a charge-level pop-up appears on the screen; on iPhones, this feature only works for models with a W1/H1 chip (such as AirDots Pro 2).
3.By the indicators on the case
Most Xiaomi models have LED indicators:
- π’ Green: Charge over 60%.
- π‘ Yellow/orange - 20β60%.
- π΄ Red: Less than 20% or charging error.
- π Blinking white β headphones are connected to the case and charged.
πΉ Note: Redmi Buds 4 Lite indicator only on the case β the charge level of the headphones can be found only through the application.
What to do if the indicator is not burning?
Typical charging errors: what shortens battery life
Many users inadvertently ruin headphone batteries by following "people's advice." Consider the most common mistakes and their consequences:
β οΈ Warning: Leaving your headphones on charge for more than 24 hours (e.g. on weekends) can cause overcharging and 10 to 15 percent less capacity per year. Current controllers protect against this, but the risk remains.
- π Use of unoriginal cables. Cheap cables may not meet standards. USB-IF, This leads to unstable voltage and battery heating.
- βοΈ Charging in the sun or near heat sources. +40Β°C destroys lithium polymer cells, like if you leave a case on a car torpedo in the summer.
- π Discharge to 0% before charging. Lithium polymer batteries are harmful to both full discharge and constant charging to 100%. Optimal range: 20-80%.
- π΅ Using headphones while charging, which increases battery load and can cause it to swell (especially on budget models).
πΉ Fact: According to a study by Battery University, storing headphones with a charge of 100% at temperature +30Β°C reduces battery life by 40% in 3 months.
Use the original cable and power supply
Charge at a temperature of +15... +25 Β° C
Do not leave on charging for more than 12 hours
Store with a charge of 40-60% (if not used for a long time)
Avoiding a discharge below 10%-->
How to speed up charging: working ways
If you need to charge your headphones quickly, use these methods (proven on Buds 4 Pro, Redmi Buds 5 and AirDots 3 Pro models):
- Use an 18W+ power supply (if the model supports fast charging). For example, the Xiaomi Mi 11 charger reduces the charging time of the Buds 5 Pro by 20%.
- Turn off the headphones before charging. To do this, press and hold the touchpad on both headphones for 5 seconds (until the beep).
- Charge from USB-port of the laptop (if there is no original block). USB 3.0 (blue) gives more current than USB 2.0.
- Use the airplane mode on your smartphone if the headphones are connected, which will reduce the power consumption of Bluetooth.
πΉ Important: Fast charging increases the battery load. Don't use it all the time, only in emergency situations.
For models with wireless charging (Xiaomi Air 2 Pro, Buds 3T Pro), the speed depends on the power of the charging station:
- π 5W β standard speed (1.5-2 hours to 100 hours%).
- β‘ 10W+ β 20-30 acceleration%.
- β 15W+ β Possible overheating (not recommended).
π‘
The fastest way to charge Xiaomi headphones is to use the original 18W+ power supply and turn off the headphones before charging, which reduces time by 30-40% for fast-charging models.
Frequent problems and their solutions
If Xiaomi headphones donβt charge or take too long to charge, use this guide:
| Problem. | Possible cause | Decision |
|---|---|---|
| Case's not charging. | Faulty cable/power supply | Try another cable and block. Check the connector for debris. |
| Headphones don't charge in the case | Oxidation of contacts | Clean contacts on headphones and in the case with an alcohol napkin. |
| Slow charging. | Battery wear and tear | Check the number of charging cycles in the Mi Fitness app. If you wear >50%, you need to replace the battery. |
| Case is warming up | Use of a powerful power supply (>20W) | Use the 5V/1A or 9V/2A unit (for fast-charging models). |
πΉ Tip: If the headphones stopped charging after falling or getting moisture, do not try to disassemble them yourself. Contact the service center - in 60% of cases, the problem is solved by replacing the charging controller.
β οΈ Warning: Do not use abrasive materials (such as sandpaper) or metal objects to clean contacts, which can damage the protective coating and cause short circuits.
