Fast charging is one of the key benefits of Xiaomi Redmi Note 10 smartphones, which allows you to restore battery power in minutes. However, in some cases, users want to turn off this feature: whether it is a desire to extend the battery life, avoid overheating the device or just experimenting with alternative power modes. Unlike flagship models, where the option to turn off fast charging is often available out of the box, in Redmi Note 10 this process requires additional manipulation – or even interference with system settings.
In this article, we will discuss all the working ways to disable fast charging on the Xiaomi Redmi Note 10, including official methods through MIUI settings, hidden engineering menus and third-party utilities. We will focus on the risks associated with changing charging parameters, and explain why some methods can lead to irreversible consequences for the battery. If you are looking for a way to reduce battery load without losing functionality, here you will find proven solutions.
Why do users want to turn off fast charging?
At first glance, being able to charge a smartphone in 30 to 40 minutes seems ideal, but fast charging has a downside that forces Redmi Note 10 owners to look for ways to deactivate it.
- 🔋 Battery degradation: Lithium-ion batteries wear out faster at high charging currents. Research suggests that using fast charging can reduce battery life by 15-20 percent after 1-2 years of active use.
- 🔥 Overheating of the device. With fast charging, the temperature of the Redmi Note 10 body can rise to 40-45°C, which negatively affects not only the battery, but also the performance of the processor.
- ⚡ In regions with frequent voltage surges, fast charging can cause power controller failures, especially if a non-original adapter is used.
- 🛠️ Repair or diagnostics: Service center wizards sometimes recommend turning off fast charging when checking power chains or after replacing the battery.
It is important to understand that turning off fast charging does not always solve battery problems, for example, if the battery is already worn out (capacity below 70% of nominal), reducing the charging current can only slow down its degradation slightly, but will not restore its original characteristics.
Official method: settings MIUI
The safest method is to use the built-in MIUI options. Unfortunately, the standard Redmi Note 10 firmware (models M2101K6G, M2101K6I, M2101K6P) does not have a direct option to "Disable Fast Charging." However, some versions of MIUI 12.5+ and MIUI 13/14 offer the option to limit maximum current. Here's how to do this:
- Open Settings → Battery and Performance.
- Go to the Battery Settings section → Charging modes.
- Select the option of Normal Charging (if available) or Optimized Charging.
- Activate the slider Limit the charging current (in some firmware called sparing mode).
If your MIUI version doesn’t have these items, try updating your firmware to the latest stable version via Settings → About Phone → System Update. It’s also worth checking for the option in Settings → Additional → Special Features → Power Modes.

⚠️ Note: In some regional firmware (e.g. India or China), the option to limit charging current may not be available due to local safety standards, and alternative methods may have to be used.
Hidden Engineering Menus: How to Limit Charging Current
If there are no official options, you can try changing the charging options through the Engineering Mode, a method that requires caution, as incorrect settings can lead to malfunctions in the power controller.
- Open the Phone app and enter the combination: ##4636##.
- In the menu that opens, select Battery Information.
- Scroll down to Charging and find AC Charge Limit or Fast Charge Config.
- Change the value from Enabled to Disabled (or set a current limit of 1000 mA to simulate standard charging).
If #4636### doesn’t work, try the alternative codes:
- #36446337## - Hardware Test Mode
- #284## - Battery test
- ##232338## - Wireless module information (may contain power partitions)
After changing the settings, restart the device. If the smartphone started charging slower, then the restriction worked. If not, the settings could have been reset by the system (this happens on custom firmware).

Third-party applications: risks and opportunities
If system methods fail, you can use third-party applications such as AccuBattery, Battery Charge Limit or Quick Charge Switcher, which allow you to control the charging current, but have limitations:
- 📱 AccuBattery – monitors battery status and suggests limiting charge to 80%, but does not turn off fast charging completely.
Before installing, check the app’s compatibility with your Redmi Note 10 model. AccuBattery works on most devices, for example, but you’ll need a ROOT or unlocked bootloader to fully control the charging current.
⚠️ Attention: Use of applications with ROOT-In addition, incorrect settings can lead to a complete failure of the power controller, which will require repairs in the service center.
💡
If you choose to use AccuBattery, turn on the “Attend at 80% charge” option in the application settings and turn off the power manually, which will reduce the battery load without risk to the system.
Hardware methods: charging through USB-hub
If the software isn't working, you can use hardware constraints, like charging the Redmi Note 10 through an intermediary that will lower the current:
| Method | Current restriction | Pluses | Cons |
|---|---|---|---|
| Charging through USB-hub | 500 to 1,000 mA | No changes to the phone, it is safe. | Slow charging (up to 5-6 hours) |
| Use of Power Bank | 1000-1500 m | Mobility, you can control the process | Not all power banks support current restriction |
| Charging from USB-port | 500 m. | Maximum sparing regime | Very slow, inconvenient for constant use |
| Using a "smart" socket | Depends on the model. | You can program the charging time. | It does not affect the current, only the duration. |
For example, if you connect a Redmi Note 10 ce USB-port of a laptop or old charger with an exit 5V/1A, The phone will charge as standard, and this is completely safe, but it takes patience: it can take up to a full charge. 6–8 hours.
💡
Hardware methods are the only way to turn off fast charging without risking firmware. They are suitable for temporary use, but do not solve the problem completely if you need to constantly charge your phone in gentle mode.
What happens if you turn off fast charging: pros and cons
Before you make a decision, weigh the pros and cons. Disabling fast charging has both obvious advantages and hidden disadvantages:
- ✅ Pluses: 🔋 Increase battery life by 20–30% with regular use. 🌡️ Reducing the heat of the device during charging (especially relevant in hot climates). 🛡️ Less risk of stress surges with unstable eating.
- ❌ Cons: ⏳ Charging time increases from 1-1.5 hours to 3-5 hours. 🔌 Some adapters may not work properly in standard mode (e.g., stop being recognized). 🔄 When returning to fast charging after prolonged use of sparing mode, the battery may temporarily lose capacity.
If you use the Redmi Note 10 as your primary device and often discharge it to zero, turning off fast charging may be justified. However, for users who recharge the phone a little during the day, the difference in battery wear will be minimal.
Frequent Mistakes and How to Avoid Them
When trying to turn off fast charging, many users encounter typical problems, and here are the most common mistakes and ways to solve them:
- 🔄 "Settings are reset after the reboot, meaning that changes to the engineering menu have not been saved to the NVRAM. Try repeating the procedure or using the app with ROOT-rights.
- ⚡ "Phone doesn't charge at all" - you may have set a too low current limit (less than 500 mA.
- 📱 "The app does not see the charging controller" - check the utility's compatibility with your Redmi Note 10 model (for example, check the compatibility of the utility with the Redmi Note 10 model (for example, the app does not see the charging controller, M2101K6G You may need a special version of the software).
- 🔥 "The device warms up a lot even after the fast charge is turned off - the problem may be a faulty battery or charger.
If none of the methods worked, it is worth considering alternative options: for example, replacing the battery with a new one (or from a proven manufacturer) or using an external battery with a slow-charging function.
