The Xiaomi M365 remains one of the most popular vehicles in the city, but the question of how long does it charge? is still controversial. Official data from the manufacturer says that it takes 5-5.5 hours to fully charge, but in practice this time can vary from 3 to 7 hours - it all depends on the state of the battery, the type of charger and even the temperature in the room.
If you notice that your M365 Been charging longer than usual or, conversely, gaining too quickly 100%, This is a reason to check the battery and operating conditions, and in this article we will examine not only the standard charging time, but also the factors that affect it. 5 We're going to focus on common errors that reduce the life of lithium-ion cells. 30-40%.
Official data: how much should be charged Xiaomi M365 passport
According to the technical documentation of Xiaomi Mi Electric Scooter M365, a full charge cycle from 0% to 100% takes 5-5.5 hours when using the original charger (output voltage 42V/1.7A). This time is calculated for new batteries at room temperature (+15... + 25 ° C) and the voltage of the 220V network.
But these numbers are an idealized scenario, and real time depends on:
- 🔋 Current charge level: 20% to 80% of battery charge faster than last 20%
- 🌡️ Ambient temperatures: when +5°C time increases by 20-30%
- 🔌 Quality of the socket and wire: weak contact or low voltage in the network lengthens the process
- 📉 Battery wear: after 300-500 cycles capacity falls, and charging takes longer
Important: Xiaomi M365 Pro (modification with increased battery) charges longer - up to 7-8 hours, as its battery has a capacity of 474 Wh against 280 Wh in the standard model.
Table: Charging time Xiaomi M365 depending on the level of discharge
| Charge level when connected | Time up to 100% (original ROM) | Time up to 100% (non-original 2A) | Notes |
|---|---|---|---|
| 0-10% | 5-5.5 hours | 4.5-5 hours | Maximum battery load, possible heating |
| 20-30% | 3.5-4 hours | 3-3.5 hours | Optimal range for regular charging |
| 50% | 2-2.5 hours | 1.5-2 hours | Fast “recharging” without harm to the battery |
| 80-90% | 1-1.5 hours | 0.8-1 hour | The last 20% are charging more slowly due to the BMS algorithm. |
Critical information: if your scooter charges for longer than 7 hours at room temperature and the original RAM is a sign of a malfunction of the battery or BMS controller. In 80% of cases, the problem is solved by calibrating the battery (discharge to 0% + full charge 2-3 times in a row).
5 Factors That Prolong Charging Time (And How to Eliminate Them)
If your M365 used to charge in 4 hours and now requires 6-7, it's not the lag of the equipment that's to blame, but the specific reasons.
- Battery wear: After 500 cycles, the charge/discharge capacity drops by 20-30%, the solution is to replace the battery or use Eco mode to reduce the load.
- Low temperature: at +5°C and below, the chemical processes in the lithium-ion cells slow down, the solution is to charge in a warm room (at least +10°C).
- Non-original charger: A RAM with an output current >1.7A can damage the battery, and <1.5A can increase the charging time. The solution is to use only the original RAM 42V/1.7A.
- Problems with BMS-charge: Cell balancing controller may fail, causing one of the cans to charge more slowly.Solution - diagnostics at the service center.
- Deep discharge: If the scooter has been discharged for more than a month, the first charge can take up to 10 hours, the solution is to keep the discharge below 10%.
The temperature in the room (optimally +15... + 25 ° C)
The condition of the socket and wire (is there no heating?)
Originality of charger (the label must be 42V/1.7A)
Battery wear level (in the Mi Home app, check the number of cycles)
BMS errors (does the red light flash on the charge?)

How to speed up charging Xiaomi M365: 5 working ways
If you need to charge your scooter urgently, these methods will help reduce time by 20-40% without harming the battery (assuming the battery is in good condition):
- ⚡ Use an “intermediate” charger: instead of 0→100% charge off 20% before 80%. It cuts the time by 30-40% and extends the battery life.
- 🔥 Warm up the battery: if the scooter was brought from the cold, let it stand in the warm 15-20 minutes before charging. Do not use hair dryers or heaters!
- 🔌 Turn off all consumers: turn off the lights, Bluetooth and the Mi Home app while charging. Even the indicators are consuming. 1-2% energy.
- 📱 Update the firmware BMS: In new versions of the software, the charging algorithms are optimized. The update is available through the official application.
- 🔄 Calibrate the battery every 3 months: completely discharge the scooter (before switching off), then charge to 100% without interruptions.
💡
If you need to urgently reach, and the battery is discharged, charge the scooter for 30-40 minutes - this will be enough for 10-15 km of travel in Eco mode. The main thing is not to exceed the speed of 15 km / h, so as not to load the battery.
Dangerous myths: what you should not do when charging Xiaomi M365
The Internet is full of “advice” that not only does not speed up charging, but also kills the battery in 2-3 months.
⚠️ Note: Using a charger from Xiaomi M365 Pro (42V/2A) For the standard model, it will accelerate charging 15-20%, reduce the battery life of the 30%. Controller BMS powerless!
- 🔥 Myth 1: “Charge the scooter in the cold – so the battery will not overheat” Reality: at a temperature below +5°C lithium-ion cells lose up to 50% of their capacity and may not recover even after heating.
- ⚡ Myth 2: “If you charge from powerbank, it will be faster” Reality: Most power banks issue unstable voltage, which leads to failures BMS. Consequences: the scooter may not turn on or show an incorrect charge level.
- 🔋 Myth 3: «You always have to discharge until 0% For calibration" Reality: Deep discharge (below) 3.0V It breaks the structure of the electrodes. Consequences: the capacitance falls on the cell. 10-15% after 1-2 cycle.
What happens if you leave the scooter on charge for a week?
How to check the battery status of Xiaomi M365
If the scooter starts charging longer or runs out faster, the first thing you need to do is diagnose the battery. Here are 3 reliable ways to do this.
- Through the Mi Home app: Open the Device section → The state of the battery: 📊 Number of cycles: more than 500 - critical wear. 🔋 Capacity: If less than 70% of the original, you need a replacement. ⚠️ Mistakes. BMS: code E01-E05 They indicate cell problems.
Multimeter
Measure the voltage at the battery terminals at 100% charge. The M365 is normal for 41.8-42.0V. If below 40V, the cells are out of balance.
Load test
Charge the scooter fully, then drive 10km at top speed, and if the charge drops by more than 30 percent, the battery is worn out.
For accurate diagnostics, you can use specialized testers like YR1035 or Soshine SC020, which show the voltage of each cell separately, and the difference between cells greater than 0.1V suggests that balancing is necessary.
💡
If the battery capacity has fallen below 60%, and the scooter travels less than 15 km on a single charge - it is more cost-effective to buy a new battery (about 8000). ₽), Refurbished batteries rarely last more than 6 months.
