Charging time Xiaomi Earbuds: what depends on and how to check

Xiaomi Earbuds wireless headphones have become an integral part of everyday life due to their convenience, compactness and high-quality sound. However, one of the key questions that users care about is how long it takes to fully charge both the headphones themselves and the case, the answer depends on the model, the type of charger and even the ambient temperature.

In this article, we will analyze the exact data on charging time for all popular Xiaomi Earbuds models (from budget AirDots to flagship Buds 4 Pro), as well as give practical tips on how to speed up the process and avoid the typical errors that shorten battery life. If you notice that the headphones began to charge longer than usual, here you will find the reasons for this problem.

First, it is important to understand: the charging time is specified by the manufacturer for ideal conditions - when using the original cable, a charger with sufficient power and a temperature of +20... + 25 ° C. In reality, these parameters can vary, so we will give not only official data, but also the results of user tests.

Official data: charging time by models

The table below shows passport charging times for popular Xiaomi Earbuds models, which are relevant for new devices with a serviceable battery and original charging equipment.

Note that models with fast charging support (such as the Buds 4 Pro) have 10 minutes in a case for 2-3 hours of battery life, which is critical if the headphones run out at the most inopportune time.

Also, it is worth considering that the charging time of the case and headphones inside the case is different values. For example, AirDots Pro 2 case charges in 1.5 hours, and the headphones themselves (if they are completely discharged) - in 1 hour when connecting the case to the network.

Factors affecting charging speed

Even if you use the original cable and power supply, the actual charging time may be different from the passport.

• 🔌 Power of charger. Power supply to power supply 5W (standard USB-PC ports) charge headphones in 1.5-2 times slower than the adapters on the 10W Like Buds, you know. 4 Pro 18W-The adapter is charged for 30 minutes, and from laptop to 1.5 hours.
• 🌡️ Ambient temperature, lower temperature +10°C lithium polymer batteries are charged on 30-50% Slowly, but with +35°C and above, overheating protection is triggered, and charging may be interrupted.
• 🔋 Battery status, after 300-500 Charging cycles battery capacity is reduced by 20-30%, This increases the charging time, and this is especially noticeable in older AirDots models.
• 📶 Background processes: If the headphones are connected to the phone while charging (for example, for firmware), the process may slow down. 10-15%.

⚠️ Note: Using non-original thin wire cables (such as cheap no-name cables from China) can not only increase charging time, but also damage the power controller in the case, especially for fast-charging models (Buds 3 Pro, Buds 4 Pro).

Interesting fact: some users note that charging from a power bank (external battery) is slower than from an outlet, due to the limitation of current at the output of many power banks (usually 1A instead of 2A). If you need to charge headphones on the road, choose a power bank with support for Quick Charge 3.0 or PD (Power Delivery).

💡

If your Xiaomi Earbuds are charging longer than before, try resetting them to factory settings via the Mi Earphones app (Reset section), which often helps with power controller failures.

How to check the level of charging headphones and case

You can find out the current charge of the headphones and the case in several ways.

1. Most Xiaomi Earbuds models have an LED on the front of the case that burns: 🔴 Red - charge less than 20% 🟡 Yellow/orange — 20-80% 🟢 Green — 80-100%

The Buds 4 Pro display is more accurate: 4 white LEDs show charge in 25% increments.

The first generation Xiaomi AirDots models often have a problem when the case shows 100% charge, but the headphones inside do not charge. This is due to the oxidation of the contacts – they need to be cleaned carefully with a swab or cotton swab dipped in alcohol.

How much do Xiaomi headphones hold after full charging?

Battery life is as important as charging speed, and the table below shows real-time (rather than passport) data for different models at average volume (60-70%) and ANC on (if supported).

Important: these data are relevant for new headphones, after 1-2 years of operation, the operating time is reduced by 20-30% due to battery degradation, and autonomy depends on the codecs:

• 🎵 AAC (default on iPhone – average battery consumption
• 🎵 aptX (on Android) – the cost of 10-15% higher
• 🎵 LDAC (Buds 4 Pro: Maximum quality, but battery burns 20% faster

⚠️ Note: If your Xiaomi Earbuds are discharged 1-2 At minimum volume, this could be a sign of a battery failure or software failure. Try calibrating the battery: completely discharge the headphones (before turning them off), then charge to the battery. 100% breaklessly.

How to speed up charging Xiaomi Earbuds: 7 working ways

If you need to charge your headphones urgently, use these tips:

1. Use the original cable and power supply. For example, for the Buds 4 Pro, Xiaomi’s 18W charging (MDY-11-ED model) is suitable. Cheap cables can limit current to 0.5A, which increases charging time by 2-3 times.
2. Turn off the headphones while charging, put them in the case and press the button on the case for 5 seconds (until the indicator flashes), which will turn off the background processes.
3. Charge from the socket, not from the PC / laptop. USB-Computer ports usually give you everything. 0.5-1A, while the plug adapter — 2A higher.
4. Use airplane mode. If the headphones are connected to the phone while charging, turn off Bluetooth or put the phone into airplane mode.
5. Keep your headphones at their optimum temperature. Do not charge them in cold (below +10°C) or hot places (for example, in direct sunlight).
6. Clean the contacts. Dirt or oxidation on the case and headphone contacts can impair the current transfer.
7. Update the firmware. Some models (such as the Buds 3 Pro) improve power management after the firmware update.

For models with wireless charging (Buds 4 Pro, FlipBuds Pro), the speed depends on the power of the charging station. The best option is a 10W station (Qi standard), charging from a smartphone (reverse wireless charging) is very slow and is not recommended for regular use.

💡

The fastest way to charge Xiaomi Earbuds is to use the original 18W adapter (for supported models) and charge the headphones when off.

Typical Charging Problems and Their Solutions

If Xiaomi Earbuds headphones don’t charge or charge for too long, the reasons can be both software and hardware.
