How to Know if Xiaomi Wireless Headphones Are Charged: A Complete Guide to Photos and Videos

Xiaomi’s wireless headphones are some of the most popular gadgets on the market, thanks to a combination of price, quality and functionality. But even experienced users sometimes face the problem of how to accurately determine if the headphones or case are fully charged? Unlike smartphones, where the percentage of charge is displayed on the screen, the TWS-True Wireless Stereo is often limited to flashing LEDs or beeps, and an error in interpreting these signals can cause a discharge at the most inopportune time, such as during an important call or training session.

In this article, we will analyze all possible ways to check the charge for Xiaomi headphones (including models Airdots, Buds, FlipBuds and others), explain what the colors and flashing modes of indicators mean, and also reveal little-known chips - for example, how to find out the exact percentage of charge through the Mi Home app or Xiaomi Wear.

If you have ever asked yourself questions:

• 🔴 Why Xiaomi headphones flash red when they just lay on a charger?
• 🟢 What does a permanent green light mean in a case?
• 🔵 Can you trust voice alerts about the charge?
• ⚪ How to distinguish the charge of headphones from the charge of the case?

This article will give you comprehensive answers.

1. Standard charge indicators: decoding colors and blinks

All Xiaomi wireless headphones are equipped with LED indicators that signal the status of charge. However, their behavior may differ depending on the model. Consider the general logic that is relevant for most devices (including Redmi Airdots, Mi True Wireless Earphones, Xiaomi Buds). 3/4 others).

The main colors of indicators and their values:

• 🔴 Red (blinking or constant) – low charge (less than 20%) Headphones or case require recharging.
• 🟡 Orange/yellow is the average charge level (20-80%). In some models, it can mean the charging process.
• 🟢 Green (constant) – full charge (100%) or near maximum charge (80–100%).
• ⚪ White/blue – pairing mode (not related to charge.
• 🔴🟢 Alternating red and green – charging error (check contacts or cable).

It is important to understand that the indicator on the case and the indicators on the headphones themselves can show different statuses, for example, the case can be charged 100% (green light), and the headphones inside are discharged (red light when the lid is opened).

💡

If the indicator on the case does not burn at all, try to press the pairing button (usually located on the side) - this will "wake up" the LED and show the current status.

Attention! In models with fast charging support (such as the Xiaomi Buds 4), the indicator can flash green in the first 10 minutes of connecting to the network - this is normal and means accelerated battery replenishment.

2.Audible signals: what voice alerts say

In addition to light indicators, many Xiaomi headphones use voice prompts in Chinese or English.

• 🎵 "Battery Low or Whale. — Low Charge (<10%). The headphones will soon be off.
• 🔋 "Charging" or "whale." - is charging (if the headphones are in the case).
• ✅ "Battery Full (or Whale) – Full Charge (100%).
• 🔌 "Power off or whale. – Headphones are turned off due to critical discharge.

In models of Xiaomi Buds 3/4 and FlipBuds Pro voice alerts can be disabled via the Xiaomi Wear app (Settings section) → Voice prompts.However, this is not recommended as you will lose important charge notifications.

Critical information: In the Redmi Airdots 3 Pro headphones, the "Battery full" voice alert sounds only when charged via cable, but not when wirelessly charging (Qi).

3.Charge check via app: Mi Home vs Xiaomi Wear

The most accurate way to know the percentage of charge is to use official Xiaomi apps, but there are nuances:

Appendix Mi Home (Mi Fit):

• ✅ Supports most models (including older Airdots).
• ❌ It only shows the charge when the headphones are connected to the phone (not in real time).
• 📱 Path: Profile → Devices → [Your headphones] → Battery status.

2. Xiaomi Wear app:

• ✅ More modern interface, supports new models (Buds 4, FlipBuds Pro).
• ✅ Shows the charge of the case and each headphone separately.
• 📱 Path: Devices → [Headphones] → Battery.

Attention! If the app displays a charge of 100%, but the indicator on the case flashes red, this is a sign of a malfunction of the battery controller, in which case the headphones can suddenly turn off even when "full" charge.

4 How to check the charge without phone and apps

If you do not have a smartphone at hand or the application does not connect, use these methods:

Weight test:

• 🔋 A fully charged case with headphones weighs 2-3 grams more than a discharged one (due to chemical processes in the battery).
• ⚖️ Use kitchen scales with an accuracy of 0.1 g. Compare with the data from the table:

Charging time check:

• ⏱️ The full case charging cycle takes 1.5-2 hours (for models with fast charging support - 1 hour).
• ⚡ If the indicator is gone after 30 minutes, the case is not fully charged (possibly a cable problem).

3. Use of multimeter (for advanced users):

• 🔧 Measure the voltage on the case contacts (normal: 4.2V fully charged, 3.0V — discharged).
• ⚠️ Risk of damage to the device! not recommended without experience.

5 Common Mistakes: Why Headphones Don't Charge

If the indicators behave outside the box (for example, flashing red despite prolonged charging), the reasons may be as follows:

• 🔌 Cable or adapter problems: Use Xiaomi’s original cable or a certified USB-Type-C. The power adapter should give you a power supply. ≥5V/1A (fast-charging — 5V/2A).
• 🧲 Contact contamination: Oxidation or dust on case/earphone contacts interrupts charging. Clean contacts with a cotton swab dipped in alcohol.
• 🔋 Battery wear: After 300–500 Charging cycles battery capacity falls on 20–30%. Check the operating time: if the headphones hold <2 clock - battery worn out.
• 🤖 Firmware failure: Headphone reset (press the button on the case for 10 seconds) can help.Update firmware via Xiaomi Wear.

Attention! If the case heats up during charging (temperature above 40)°C, immediately disconnect it from the mains! This is a sign of a malfunction of the power controller, which can lead to fire.

💡

If the headphones are not charged in the case, but the case itself is charged from the cable - the problem is in the contacts between the case and the headphones. Try to gently bend the contacts in the case with a thin screwdriver (at your own risk!).

6. Features of wireless charging (Qi)

Models Xiaomi Buds 3 Pro, FlipBuds Pro and some others support wireless charging according to the Qi standard.

• 🔄 Slower wired: Full charging takes 2–2.5 hours (versus 1.5 hours on cable).
• 📍 Positioning: Case should lie strictly in the center of the charging pad. 5 mm shift can interrupt charging.
• 🔋 In most models, the indicator flashes white/blue during wireless charging (as opposed to green/red for wired charging).
• ⚡ Compatibility: Not all Qi charging works with Xiaomi cases.Recommended power: 5W–10W.

To check if the charge is going on:

1. Put the case on the charging pad.
2. Open the lid - the indicator should flash white/blue.
3. Close the lid and wait 10 minutes. If the indicator hasn't changed, it's not charging.

Note: In headphones Xiaomi Buds 4 wireless charging works only at ambient temperature of 10-35°C. When you go beyond these limits, the case will not charge, even if the indicator flashes.

7.How to prolong the life of a battery: operating tips

The battery life of Xiaomi headphones depends on proper operation.

• 🔋 Avoid full discharge: Charge headphones when charge drops to 20–30%.Full discharge (0%) reduces battery life.
• ⚡ Don't keep on charging constantly: Once you reach 100%, disconnect the case from the grid. overcharging is harmful to lithium polymer batteries.
• 🌡️ Control the temperature: Do not charge your headphones at temperatures below 0°C or higher than 40°Do not leave the case under direct sunlight (for example, on a torpedo of a car).
• 🔄 Use regularly: If the headphones lie idle for more than a month, charge / discharge them to 50 every 2 weeks%.
• 🔌 Use Original Accessories: Cheap cables and adapters can damage the charging controller.

Attention! If you keep your headphones for long periods (like winter), charge the case up to 50% and disconnect it from the network, and storing it with full or zero charge leads to irreversible loss of capacity.

💡

The optimal battery storage level is 40-60%, and the chemical processes in lithium polymer cells slow down, prolonging their lifespan to 2-3 years.
