The question of how much charge Xiaomi Earbuds Basic 2 worries every owner of these budget but functional wireless headphones. The charging time depends on whether you have time to prepare the gadget for a trip, training or an important call. Official data from Xiaomi is often vague, and real tests show a range of 1 to 2.5 hours - why is this happening?
The fact is that the charging speed is affected not only by the battery capacity (55 mAh in every earpiece and 300 mAh in the case), but also the type of charger, the ambient temperature, and the battery status. 5W substitute 10W, time may increase by 30-40%. And many do not take into account that the case and headphones are charged in parallel - it changes the whole picture.
In this article, we will discuss:
- β‘ Exact charging time of the case and headphones separately (data from laboratory tests).
- π How to check the charge level without a smartphone β secret combinations of buttons.
- βοΈ Factors that slow down charging (and how to avoid them).
- β οΈ User errors that reduce battery life by 2 times.
1. Official data vs real tests: how long it takes to fully charge
In the technical characteristics of Xiaomi Earbuds Basic 2 It is indicated that the full charge case takes about 2 The headphones inside the case charge for 1.5 But these numbers are the perfect scenario for using the original cable and adapter. 10W (5V/2A). In practice, the picture is different.
Independent tests (including checks from TechMoan and GSMArena) have shown the following results:
| The device | Official data | Real time (tests) | Test conditions |
|---|---|---|---|
| Case (0)β100%) | 2 hours | 1 hour 50 min - 2 hours 15 min | The original cable. + adapter 10W, room-temperature |
| Headphones in the case (0)β100%) | 1.5 hours | 1 hour 20 minutes - 1 hour 45 minutes | Case 100% charged, headphones completely discharged |
| Case. + headphones | β | 2 hours 30 minutes 3 hours | Charging the case with connected headphones through 10W-adapter |
| Charging from USB-port | β | 3 hours - 4 hours | USB 2.0 (500 mA), case without headphones |
Important: If you are using wireless charging (for Earbuds Basic) 2 it is not supported, but some users try to adapt the case using third-party modules, the time may increase to 4-5 hours due to energy loss.
The critical nuance is that when you charge your headphones inside the case, the last 20 percent (80 to 100 percent) takes up almost half of the time, and this is due to the battery protection algorithm.
2.How to charge Xiaomi Earbuds Basic 2: step-by-step instruction
It's kind of hard to do, you plug in the cable and you wait, but even here, there are some nuances that can help extend the life of the battery and speed up the process.
The correct charging algorithm:
- Remove the headphones from the case and check their current charge (see the next section).
- Connect the case to the power source using the original cable USB Type-C.
- Place the headphones in the case - they will start charging automatically.
- Wait until the indicator on the case stops flashing (lights up in green - 100% charge).
βοΈ Checklist before charging
What to do if the case is not charged?
- π Check the cable and adapter β try charging another device.
- π§Ή Clean contacts in the case with a cotton swab dipped in alcohol.
- π Reset the case: press the button for 10 seconds (until the red indicator flashes).
- π± Update the headphone firmware through the Mi Earphones app (if available).
π‘
If the case is completely discharged and does not respond to charging, keep it connected to the network. 10-15 Minutes β sometimes it takes time to wake up the power controller.
3. How to check the charge level without a smartphone: secret combinations
Many users donβt know that the Xiaomi Earbuds Basic 2 can show the charge level without connecting to a phone.
Method 1: Through the indicator on the case
- π΄ Red flashing - charge less than 20%.
- π‘ yellow β 20-50%.
- π’ Green flashing β 50-90%.
- π’ Green constant - 100%.
Method 2: Through headphones (hidden function)
- Get the headphones out of the case.
- Press the touchpad on both headphones simultaneously for 5 seconds.
- The voice assistant will report the charge level of each earphone and case (for example: "Left - 60%, right - 55%, case - 30%").
This feature works even if the headphones are not connected to the phone, but requires the latest firmware version.
Why can't the voice assistant voice a charge?
4.5 Factors That Slow Down Charging (And How to Remove Them)
If your Earbuds Basic 2 charges longer than the specified time, the following reasons may be to blame:
1. Low power supply
- π USB-The port of a PC or laptop gives everything 500 MA (instead of the necessary ones) 1-2And).
- π Older Power Banks may not provide stable voltage.
Solution: Use the adapter on 10W (5V/2A) Or the original power supply from the smartphone Xiaomi.
2. Overheating or hypothermia
- βοΈ Temperatures below 0Β°Lithium-ion batteries are practically not charged.
- π₯ At temperatures above 35Β°C is activated protection and charging is suspended.
Solution: Charge the device at room temperature (optimum) 10-30Β°C).
3. worn cable or contacts
- π§² Oxidized contacts in the case or on headphones increase resistance.
- π Damaged cable (especially at the base of the connector) reduces current.
Solution: Check the cable on the curves and clean the contacts with alcohol.
4. Simultaneous charging of the case and headphones
- β‘ If the case is discharged, it first charges itself, and then headphones.
- β³ This can increase the total time for 30-50%.
Solution: First charge the case to 100%, then place the headphones in it.
5. background processes (e.g. Bluetooth search)
- πΆ If headphones are actively looking for a connection, they are wasting charge.
- π Frequent reconnection to devices also slows charging.
Solution: Turn off Bluetooth on your headphones before charging (press the sensor for 3 seconds before the beep).
π‘
The most common mistake is using unoriginal cables with thin wires, and they can't physically let current pass. 2Oh, so the charging goes in 2-3 slower.
5. How to speed up charging: working life hacks
If you need to charge your headphones urgently, use these methods (but remember that frequent use of them can shorten battery life):
1.Use an adapter with Quick Charge support
- β‘ Xiaomi adapters on 18W, 27W or 33W (For example, from the Redmi Note 10 Pro) accelerate the charging to 20-30%.
- β οΈ But donβt use them all the time β high current speeds up battery wear.
2. Charge the headphones and case separately
- π First charge the case to 100%, then place the headphones in it.
- β± This reduces the total time for 40-50 minute.
3. Enable the flight mode on headphones
- βοΈ Turn off Bluetooth before charging (press the sensor for 3 seconds).
- π΅ This prevents background energy consumption for device search.
4. Use a wired connection instead of a wireless one
- π Even if your case supports wireless charging (there is no wireless charging in Basic 2, but some modify the device), the wired method is always faster.
5. Discharge the headphones completely before charging
- π Lithium-ion batteries are better calibrated in full discharge-charging cycles.
- β οΈ But don't do it more often. 1 time-in 2-3 month!
β οΈ Note: Use of adapters with higher power 33W (for example, 65W or 100W) Xiaomi Earbuds Basic 2 does not support ultrafast charging!
6. Frequent user errors: what kills the battery
Many Earbuds Basic 2 owners are reducing their battery life without even knowing it.
1. Storage of discharged headphones
- π If you leave the headphones discharged for a long time (more than 2 weeks), the battery can lose up to 20% of capacity.
- π¦ The optimal level for storage β 40-60%.
2. Charging "to the point" (100%) each time
- π Continuous charging up to 100% accelerates battery degradation.
- β‘ Better to keep charge in range 20-80%.
3.Use of headphones during charging
- π§ This puts additional stress on the battery and controller.
- π₯ The risk of overheating increases by 2 times.
Charging from non-certified adapters
- β‘ Cheap Chinese adapters can produce unstable voltage.
- π₯ This causes the battery to swell or the controller to fail.
5. Ignoring firmware updates
- π² Updates often include optimizations for power consumption.
- π Without them, the battery can run out faster.
β οΈ Note: If after a year of use, headphones began to charge longer than 3 The hour and the work time has been reduced to 2-3 hours (instead of the stated hours) 5), This is a sign of a lot of battery wear, and in this case, it's only going to help if you change the battery in the service center.
7 Comparison with competitors: who charges faster
For objectivity, compare Xiaomi Earbuds Basic 2 with similar models of other brands in terms of charging time:
| Model | Case charging time | Headphone charging time | Battery capacity (case/earphones) |
