Xiaomi Redmi 10 is one of the most popular budget smartphones that supports fast charging technology. However, many users are faced with the fact that the device charges slowly, despite the stated characteristics. The reason is often due to incorrect settings, incompatible charger or software limitations. In this article, we will discuss how to enable fast charging on the Redmi 10, what nuances are important to consider and how to avoid typical errors.
The standard Redmi 10 includes a 10W charger that doesn’t unlock the full potential of the battery. Meanwhile, the smartphone supports fast charging up to 18W (in some versions – up to 22.5W). To activate this mode, it’s not enough just to connect a powerful adapter – you need to properly configure the system and meet several conditions. Next, we will examine each step in detail, from checking compatibility to optimizing the charging process.
1. Checking the compatibility of the charger
The first thing to do is make sure your charger supports Quick Charge 3.0/4.0 or similar standards (like USB-IF Power Delivery). Redmi 10 is compatible with 18W and higher adapters, but not all power supplies are equally efficient.
Pay attention to the following parameters:
- 🔌 Power: minimum 18W (optimally — 20W–30W). Adapters to 5W or 10W They will not provide fast charging.
- 🔄 Protocol: Quick Charge Support 3.0/4.0, USB Power Delivery (PD) MediaTek Pump Express.
- 🔌 Cable: Use the original cable USB Type-C or certified high-current equivalent (e.g., high-current, USB 2.0 High-speed or USB 3.0).
Importantly, even if the adapter supports 18W, but the cable is poor, the charging speed will be limited. For example, cheap thin-vein cables can choke current, negating the benefits of a powerful power supply. To test the real speed, use applications like AccuBattery or Ampere (discussed below).
2. Activation of fast charging in MIUI settings
By default, the Xiaomi Redmi 10 can limit charging speeds to extend battery life. To remove this limitation, follow the following steps:
- Open Settings → Battery and Performance.
- Go to the Battery Settings section.
- Find the option Fast Charging (or Optimized Charging) and activate it.
- If there is no option, check the section Additional settings → Charging.
Some versions of MIUI (e.g. MIUI 12.5 and later) may have different paths. If you don't find Fast Charging, try:
Update MIUI last-minute|Reset the battery settings (Settings) → Annexes → Application management → Three points. → Resetting settings)|Try another charger.|Install a charging monitoring application (e.g. AccuBattery)-->
⚠️ Note: Some Redmi 10 firmware (especially global versions) may have hidden the fast charging option, in which case resetting the battery settings or flashing on the device will help. MIUI EU (Unofficial firmware with extended functions).
3. Charging optimization: what interferes with speed
Even with the right settings and compatible adapter, Redmi 10 can charge slowly.
| Problem. | Reason. | Decision |
|---|---|---|
| Charging is going to 5W. | Activated Optimized Charging or Night Charging | Turn off the option in Settings → Battery → Battery settings |
| The smartphone is heating up and slowing down the speed | Background processes or games load the processor | Close all applications, put the phone in the Power Saving mode for charging time |
| Charging is interrupted | Poor contact in Type-C connector or damaged cable | Clean the dust connector, try another cable |
| Power jumps (e.g. 9W → 15W → 7W) | Unstable voltage in the network or a faulty adapter | Connect the charger to another power source, check the adapter on another device |
💡
If the smartphone charges slowly when the screen is turned on, try to lock it – when it is turned off, Redmi 10 can consume less energy, directing it to charge the battery.
4. Charging monitoring applications
To know exactly if fast charging works, use specialized utilities. They show real power (in watts), current and voltage. The best options for Redmi 10:
- 📊 AccuBattery displays charging speed, battery temperature and wear. The free version is quite functional.
- ⚡ Ampere shows the charging current in real time, useful for checking cables and adapters.
- 🔋 Battery Guru – monitors charging cycles and offers tips for optimisation.
Example: If the Ampere shows 1.5A at 5V, your charging goes on a standard 7.5W. For fast charging, there should be values like 3A-4A at 9V (i.e., 27W-36W, but Redmi 10 is limited to 18W).

5.Fast charging and battery health: myths and reality
Many users fear that fast charging reduces battery life. Let's see how this is true:
- ⚡ Myth: Fast charging always hurts the battery.Reality: Modern smartphones (including the Redmi 10) automatically adjust the current as they charge.After 80%, the power is reduced to reduce heating.
- 🔥 Myth: Charging on 18W Reality: Overheating is caused by background processes or a faulty adapter, not by the fast-charging technology itself.
- 📉 Myth: Fast charging reduces battery cycles by 50%.Reality: According to research, the wear difference between the two 5W and 18W totality ~5-10% in 500 cycles.
⚠️ Note: If you use unoriginal adapters with questionable quality, the risk of battery damage does increase. USB-IF, which may cause unstable tension.
6. Alternative methods of accelerating charging
If, even after all the settings, Redmi 10 charges slowly, try these methods:
- ❄️ Cool your smartphone. Put it next to the fan or remove the case, overheating reduces the charging speed.
- 🛑 Airplane mode: Shutting down the network and background processes reduces the load on the processor, allowing more power to be directed to the battery.
- 🔄 Firmware change: informal firmware (e.g., firmware change, MIUI EU Pixel Experience sometimes reveals hidden charging capabilities.
- 🔌 Some external batteries (e.g. Xiaomi Mi Power Bank 3 Pro) support Quick Charge 3.0 and can charge faster than socket adapters.
💡
The most efficient way to speed up charging is by combining a powerful adapter (20W+), high-quality cable and aircraft mode, in which case the Redmi 10 can gain 50% charge in 30-40 minutes.
7. Frequent mistakes and how to avoid them
When setting up fast charging, users often make the same mistakes, and here are the most common ones:
- Left-handed cables: Cheap cables without high-current support can not only slow charging, but also damage the Type-C port.
- Charging during games: Games load the processor, which causes the smartphone to heat up and automatically reduces the charging speed.
- Ignoring MIUI updates: Newer versions of firmware often optimize charging algorithms.
- Connection to USB-The port of the computer. USB 2.0 on PCs is usually only available 0.5A, 4-5 times slower than fast charging.
⚠️ Warning: If after connecting a powerful adapter, the smartphone begins to vibrate or squeak, immediately turn off the charger! this is a sign of incompatibility or malfunction of the power supply, which can lead to damage to the battery.
