In this article, we will analyze all the nuances of charging for different models, from the budget Redmi AirDots to the flagship Xiaomi Buds 4 Pro. You will learn how to determine the level of charge, which cable to use, how long it takes to fully charge and how to extend the battery life. And also β debunk the myths about βcorrectβ charging, which can on the contrary shorten the life of your headphones.
Which Xiaomi models support wireless charging?
Not all Xiaomi headphones are equipped with wireless charging function β this depends on the model and year of release. Here is the current list of devices with support for Qi-standard (2026):
- π§ Xiaomi Buds 4 Pro β flagship model with active noise cancellation and fast charging (10 minutes) = 3 hours of work).
- π§ Xiaomi Buds 3T Pro - improved version with hybrid ANC and wirelessly charging the case.
- π§ Redmi Buds 4 Pro β budget version with support for Qi, but without ANC.
- π§ Xiaomi Air 2S β One of the first models with wireless charging (power up to 5 W).
Note that even if your model does not support wireless charging, the case can always be wired over USB-Type-C or Micro-USB (depending on the generation).For example, Redmi AirDots 2 or Xiaomi Mi True Wireless Earphones 2 Basic are only charged with cable.
To check the wireless charging support for your model, look at the bottom of the case β it should have the Qi logo or the words Wireless Charging, and information can be found in the official specifications on the Mi.com website.
How to charge the case of headphones Xiaomi: step-by-step instructions
Charging the case is the foundation on which the headphones themselves depend, and it seems simple, but there are some critical points that many people miss, and let's look at both, wired and wireless.
Charging over the wire (USB-Type-C/Micro-USB)
This is the most reliable and quickest way.
- Connect the cable to the case. For new models (Buds 4 Pro, Redmi Buds 4), USB-Type-C is used, for old ones (AirDots) - Micro-USB.
- Connect the other end of the cable to the power supply. 5V/1A. USB-Use of chargers with higher power 10W (for example, from a smartphone) can reduce the battery life of the case on the 15-20%.
- The indicator on the case should light up red (charging is going) or white/green (fully charged).
The time of full charge of the case depends on the model:
| Model | Case capacity (mAh) | Charging time (wire) | Charging time (wireless) |
|---|---|---|---|
| Xiaomi Buds 4 Pro | 500 | ~1 hour | ~1.5 hours |
| Redmi Buds 4 Pro | 400 | ~1.2 hours | ~2 hours |
| Xiaomi Air 2S | 300 | ~1.5 hours | ~2.5 hours |

Wireless charging of the case (Qi-standard)
To charge wirelessly, you will need a Qi-compatible charging station (e.g., Xiaomi Wireless Charging Pad or any other power-hungry charging station). 5-10 Algorithm of action:
- Place the case in the center of the charging pad. It should be magnetized (most models have magnets for fixation).
- The indicator on the case will flash orange (start charging) or turn green (full charge).
- Do not move the case while charging - this can interrupt the process.
β οΈ Attention: Wireless charging heats the case more than wired charging. 40Β°C (case hot to the touch), remove it from the court and let it cool 10-15 Constant overheating reduces the battery capacity by 30% post 6 months.

How to charge the headphones Xiaomi in the case
The headphones themselves only charge from the case β they don't have a separate connector to connect the cable. It's automatic: just put the headphones in the case, and the charging starts. But there are a few things that affect speed and quality.
Here's how it works:
- Place the headphones in the nests of the case. They should be fixed by magnets (you will hear a click).
- Close the case cover. Charge only when the lid is closed. If you leave it open, the headphones won't charge even if the case is plugged into the outlet.
- Headphone indicators (if any) will light up red (discharged) or white (charged). 3T Pro) the indication is duplicated on the case.
Time to charge headphones in the case:
- π From 0 before 100%: 1-1.5 hour (depending on model).
- β‘ Fast charging: 5-10 minutes in the case gives 1-2 hours of operation (models with support for Fast Charge).
- π Charging cycles: Case designed for 3-5 Full headphone charges (for example, Buds) 4 Pro gives you a shot. 30 self-dependency: 6 headphone + 4 case-load).
If the headphones are not charged in the case, the reasons may be as follows:
- π The case is discharged - connect it to the charging.
- π§² Contacts are contaminated - wipe them with an alcohol wipe.
- π Headphones are not inserted correctly - check the magnet fixation.
- π§ Software glitch β try resetting your headphones (instruction below).

How to check the charge level of the case and headphones
You can find out the current charge in a number of ways, depending on the model and the firmware. Here are all the methods available:
1. Through the indicators on the case
Most Xiaomi cases have an LED indicator that shows the charge level:
- π΄ Red flashing: charge less than 20%, need to be urgently recharged.
- π‘ Orange: charge from 20% to 80%.
- π’ Green/white: charge above 80% or full charge.
- π Flashing green: charging process is underway (for wireless mode).
In some models (for example, Buds 4 Pro) indicator is multicolored and shows the exact percentage of the case charge when you press the button:
- π΄ 1 flashing = 25%
- π‘ 2 flashings = 50%
- π’ 3 flashings = 75%
- π΅ 4 flashings = 100%
2. via the Mi Fitness or Xiaomi Wear mobile app
For models with application support (e.g. Buds) 3T Pro, Buds 4 Pro, you can see the exact percentage of charge:
- Connect the headphones to the smartphone via Bluetooth.
- Open the Mi Fitness app (or Xiaomi Wear for new models).
- Go to the Devices section β [Your headphones].
- The screen will display the charge of headphones (left / right) and the case.
If the app doesnβt show charge, upgrade to the latest version or reconnect the headphones.
3. Through a notification on a smartphone (Android/iOS)
On Android (especially on smartphones) Xiaomi/Redmi/POCO) When you open the case lid, you get a charge-level pop-up. On iPhone, this feature only works for models with a chip. W1/H1 (Xiaomi does not have such, but you can use the Battery widget in the control panel.
β οΈ Note: If the case shows 100% charge, but the headphones discharge too quickly (less than 2 hours of operation), this is a sign of battery wear!
How long do you need to charge your Xiaomi headphones and case?
Charging time depends on three factors: device model, type of charging (wired/wireless) and current charge level, and the current data for popular models (tested in 2026) are below.
| Model | Charging the case (0)β100%) | Charging headphones (0)β100%) | Autonomy (headphones) | Autonomy (with case) |
|---|---|---|---|---|
| Xiaomi Buds 4 Pro | 1 h (wire) / 1.5 h (wireless) | 1 hour | 6 hours | 30. |
| Redmi Buds 4 Pro | 1.2 h (wire) / 2 h (wireless) | 1.2 | 5 p.m. | 22. |
| Xiaomi Air 2S | 1.5 h (wire) / 2.5 h (wireless) | 1.5 hours | 4 hours | 18. |
| Redmi AirDots 3 | 2 h (wire only) | 1.5 hours | 4 hours | 12. |
It is important to understand that real time may differ due to:
- π Power supply: charging from the laptop (USB 2.0) It is slower than the network adapter. 5V/1And.
- π‘οΈ Ambient temperatures: at lower temperatures 0Β°C or higher 35Β°C charging speed drops to 30-40%.
- π Battery wear: after 300-500 The charge cycles the case capacity decreases by 20-30%, and charging time increases.
If the case is charged for more than 3 hours, this is an occasion to check the cable, power supply or contact the service.
π‘
Optimal time to charge - when the case charge level has dropped to 20-30%. Continuous maintenance 100% The battery reduces the battery life of the 10-15% yearly.
Frequent charging errors and how to avoid them
Many users make the same mistakes that lead to rapid battery wear or breakage of headphones. TOP-5 The most common mistakes and how to fix them:
- β‘ Using βfastβ charging from smartphones (18Watt+): Powerful adapters (e.g. from Xiaomi) 12T Pro) supply too high a current, which heats the battery case. 5V/1A or the original cable from the set.
- π₯ Charging at extreme temperatures: If the case is hot in the sun or cold (for example, after the street in winter), let it warm up/cool down to room temperature before connecting to the network.
- π΅ Storage of a discharged case: If you do not use headphones for more than a week, leave the case with a charge 40-60%. Full discharge (0%) It can kill the battery for 1-2 month.
- π§² Incorrectly installing headphones in the case: If the headphones are not magnetized to the contacts, charging will not work.
- π Continuous charge "up to" 100%": Lithium-ion batteries (which are in cases) do not like a constant maximum. 80-90% and not leave on the charge overnight.
Another common problem is that the case doesn't hold a charge. 4-5 once, and now only 1-2, The reasons may be so:
- π Natural wear: after 2-3 Battery capacity is falling over the years, so the solution is to replace the battery in the service.
- π Non-original cable: cheap cables may not provide the right current. Use only certified accessories.
- π§ͺ Battery bloating: if the case starts to close poorly or the lid "bulges out", immediately stop using.

How to extend the life of the battery case and headphones
Average battery life in wireless headphones β 2-3 year 300-500 But with proper care, this time can be extended to 4-5 Here are the proven recommendations from Xiaomi engineers:
1. Optimal charging mode
- π Keep the case charge in range 20-80%. Permanent grades up to 0% and charges up 100% shorten the life of the battery in 2 once.
- β‘ Use slow-charging (5V/1A instead of fast, it reduces heat and stress on the battery.
- π Donβt leave the case on charging any more. 2-3 hours after 100%. Excess time under current damages the battery.
2.Conditional conditions
- π‘οΈ Keep the case at temperature. 10-30Β°Avoid direct sunlight (e.g., on a car torpedo in summer).
- π§ Avoid humidity. If your headphones get wet, dry them for at least 24 hours before charging.
- π§ If you donβt use your headphones for a long time (month)+), Charge the case up to 50% and store it in a dry place.
3. Proper operation
- π§Ή Once a month, clean the contacts of the case and headphones with a dry soft brush or cotton swab. Dust and dirt worsen charging.
- π Don't turn your headphones on at full volume all the time. This puts more stress on the battery.
- π If the headphones have not been used for a long time, before charging, let them "warm up" before charging" 10-15 minutes at room temperature.
By following these rules, you can increase the battery life on the 30-50%. For example, if the case usually holds the charge 1.5 year, with careful handling β 2.5-3 year-end.
β οΈ Warning: If the case has stopped charging at all (the indicator does not burn, even after resetting), do not try to disassemble it yourself! Inside a lithium-ion battery, which can ignite if damaged.
