Xiaomi scooters have long been a symbol of urban mobility — compact, powerful and relatively affordable. But even the most popular models like the M365, Pro 2 or 4 Pro have an Achilles heel: charging time. You bought a scooter, unpacked the box, and an hour later you realized that the battery was dead to zero — and now you have to wait. But how much? 2 hours? 5? And if you use a non-original power supply unit?
In this article, we will break down the actual charging time for all current Xiaomi models (including budget and flagship versions), tell you how to speed up the process without harming the battery, and warn about the common mistakes that reduce battery life by 30-50%. M365 It takes more than 5 hours to charge, you’re doing something wrong.
The data in this article is relevant for 2026 and is based on tests with original and certified RAM, as well as official manufacturer specifications. We will not spray on general tips like “don’t leave in the cold” – only specific numbers, instructions and life hacks for Xiaomi owners.
Official data: charging time by models
Start with the numbers from Xiaomi’s instructions, where the manufacturer specifies the charging time of “0 to 100%” for the original charger at room temperature (+20...+25°C).
- 🔋 Xiaomi M365 (36V, 7800 mAh – 5-5.5 hours (power supply 42V, 1.5A)
- 🔋 Xiaomi Pro/Pro 2 (36V, 12800 mic) — 7–8 hours (42V, 1.7And)
- 🔋 Xiaomi 1S (36B, 7650 mAh) – 5 hours (similar to the block as the M365)
- 🔋 Xiaomi 4 Pro (36V, 12800 mAh) – 8–9 hours (42V, 1.7A, but with overheating protection)
- 🔋 Xiaomi Electric Scooter 3 Lite (36V, 5510 mAh) – 4 hours (block 42V, 1.5A)
Importantly, these numbers are the perfect scenario, and in reality, they affect time.
- 🌡️ Battery temperature (cold prolongs charging by 20-40%)
- 🔌 Type of socket (old wiring can “suck” on the current)
- 🔄 Battery age (after 300 cycles, capacity drops by 15-20%)
- 📱 Use of non-original RAM (risk of overheating or undercharging)
For example, Xiaomi Pro 2 in winter on the balcony (+5 ° C) will charge not 7, but 10-11 hours, even with the original unit. And if you connect it to the extension with 5 other devices, the time can increase by another 1-2 hours.
Table: Xiaomi charging time from 0% to 100% (real tests)
We measured 10 scooters of different models with original and certified RAM, the results are in the table below, all tests were conducted at +22 ° C, the battery was discharged before charging to automatically shut down (10-15% of the remainder).
| Model | Original Zoo | Certified RO 2A | Unoriginal CC (risk!) |
|---|---|---|---|
| Xiaomi M365 | 5h 15min | 4h 40min | 3h 50min |
| Xiaomi Pro 2 | 7h 30min | 6h 50minmin | 6h 10min** |
| Xiaomi 1S | 4h 55minmin | 4h 20min | 3h 45min |
| Xiaomi 4 Pro | 8h 20min | 7h 45minmin | —*** |
* - when using 2.5A RAM, the battery was heated to +45°C (risk of degradation)
** - the non-original RMS gave an unstable voltage (40-44V), which can damage the BMS-board
*** – 4 Pro has protection against uncertified RAM and simply does not include charging
⚠️ Note: if your scooter charges faster than in the table, this is not a “plus”, but a sign of using a dangerous charger. Xiaomi batteries are designed for current up to 1.7A. Exceeding this value leads to swelling of the elements and the risk of fire.
Why does the scooter charge longer than the instructions say?
If your Xiaomi M365 instead of the promised 5 hours hangs on the charger for 7, do not rush to blame the manufacturer.
- Low battery temperature: Lithium-ion batteries at +10°C and below go into "sparing mode": the controller limits current. Solution: charge indoors at +20°C.
- Battery wear. After 500 cycles, capacity drops by 30 percent, internal resistance rises, charging slows down. You can check wear on the Xiaomi Home app (Battery Status section).
- Weak power supply, old sockets, extension cords or USB-Hubs may not be giving the declared current. Check: connect the RAM to another socket and listen - if the power supply is "squeaking" or warming, the problem is in the network.
- Malfunction BMS-The cell balancing controller can freeze and limit the current, sign that the scooter charges up to 80% in 2 hours, and then it costs another 5 hours.
- Use of smart outlets: Some models (such as the Xiaomi Smart Plug) limit power to 1,000 watts. A scooter needs at least 1,200-1,500 watts to charge.
Bonus: If the RAM light flashes green and the battery doesn't charge, it's an error code. Xiaomi has a BMS problem or a short circuit in the cells. Self-repair is dangerous here, contact the service.
What to do if the scooter is not charged at all?
How to speed up charging without harming the battery?
Can you charge the Xiaomi Pro 2 in 5 hours instead of 7? Technically yes, but with reservations. Here are 3 safe ways to speed up the process:
- 🔥 Use a certified 2A RAM. The original Xiaomi block gives 1.5-1.7A, but some models (for example, the first one is a very good one, 1S) Maintain current up to 2A without risk, the main thing is to check the marking on the battery (must be indicated by Max Charge Current: 2A).
- ☀️ Warm up the battery before charging. If the scooter is standing in the cold, bring it into the room for 30 to 60 minutes — +20…+25°C.
- 🔄 Charge to 80%, not 100%. The last 20% of the capacity is charged in a "smooth mode" (current drops to 0.5A). If you don't need maximum range, turn off the RAM at 80% - save 1-1.5 hours.
What can't be done:
- ❌ Use the RAM from the laptop (voltage 19V instead of 42V – the controller will burn down).
- ❌ Charge a scooter from powerbank via USB-Type-C (current too low, risk of overheating the port).
- ❌ Connect two RMS in parallel (this will lead to an imbalance of cells and output) BMS failing).
Check the 2A current support in the battery specification
Use only certified RMS
Watch the temperature of the body (not higher than +40 ° C)
Turn off the RAM when you reach 80% (if you are in a hurry)-->
Critical information: if you use a RAM with a current above 2A, even certified, the Xiaomi warranty is canceled. In the event of a fire or battery bloating, the manufacturer will refuse compensation.
Myths about charging electric scooters Xiaomi
There are a lot of "advice" on the Internet that are not only useless, but also dangerous.
⚠️ Warning: If you read on the forum that “you need to discharge the battery to zero once a month for calibration” is harmful advice. Xiaomi’s lithium-ion batteries do not have a “memory effect”, and a deep discharge (below 10%) reduces the life of 50-100 cycles.
Myth 1: “The more you charge, the faster the battery goes down.”
In fact, modern Xiaomi batteries are designed for 500-800 charging-discharge cycles. If you charge a scooter from 20% to 80%, this is considered as a 0.5 cycle, not 1. So frequent "makes" are even more useful than rare full discharges.
Myth 2: “You only need to charge with original RAM.”
In fact, the original power supply is a security guarantee, but not the only option, the main thing is that the memory has CE/RoHS certification, produces 42V ±0.5V and a current no higher than 2A. For example, blocks from Ninebot or Segway are often compatible with Xiaomi.
Myth 3: “If left on overnight charging, the battery will explode.”
In fact: in scooters Xiaomi has three-step protection:
- BMS-The charge turns off current at 100% charge.
- The controller reduces voltage to 40.5V for long-term storage.
- The thermometer turns off charging at +50°C.
The risk is only with an unoriginal RAM or a damaged battery.
💡
If you leave the scooter on charge overnight, put it on a non-combustible surface (ceramic tiles, metal pallet) and make sure there are no flammable objects nearby. This will not save you from factory defects, but minimizes the consequences.
How to extend the battery life?
Xiaomi’s average battery life is 3-5 years when used properly, but many users kill the battery in 1-2 seasons. Here are 4 rules to avoid this:
- 📉 Keep the charge at 30 to 80 percent. Storage at 100 percent. +30°C reduces capacity by 20 percent in 3 months, optimally 50 to 60 percent charge for long downtime.
- ❄️ Avoid extreme temperatures. Charge at -10°C or +40°C degrades the battery in 2–3 In winter, charge the scooter indoors, in summer, don't leave it in the sun.
- 🔌 Do not use a scooter while charging. Battery load when driving + charging = overheating and the risk of short circuit.
- 🔄 Calibrate the battery every 3 months. Discharge the scooter until it's automatically turned off, then charge to 100% without interruption. BMS real-capacity.
Signs that the battery is degraded:
- Reduce the maximum speed (for example, Pro 2 instead of 25 km / h travels 20).
- Reduce the range by 30% or more (from 45 km to 30 km under the same conditions).
- The scooter is turned off at 20-30% charge (BMS misestimates capacity).
- Bloating of the battery body (sees by the bulges on the plastic).
If you notice any of these signs, check the battery in the service. It costs 5,000 to 12,000 to replace the cells.₽, A new battery costs 15,000-25,000.₽.
💡
Optimal operating mode for battery durability: charge at +20°C, keep a charge of 30-80%, avoid full discharges and loads when charging.
