Owning a modern smartphone like the Xiaomi Redmi 10S involves a powerful battery and accelerated power recovery technology. However, not everyone likes it when the device charges too fast, causing the case to heat up or creating power surges in the network.
The Android-based MIUI operating system lacks a single “Disable Fast Charging” button in the standard settings menu, which is for the convenience of most users, but Redmi 10S owners may face the need to force a standard current transition. There are several proven methods for solving this problem, from simple physical manipulations to using an engineering menu.
In this article, we will take a look at all the available ways to limit charging speed, learn how to use software constraints, special cables and system commands, and explore the effects of high temperature on the chemistry inside the battery and why controlling charging speed can be a key factor in the longevity of your gadget.
Why you should limit the charging speed of the Redmi 10S
The fast-charging technology, known as Quick Charge or MI Turbo Charge, allows the battery to be replenished in a short time. However, this process is accompanied by increased heat generation. For the Redmi 10S, which is equipped with a MediaTek Helio G95 processor, the additional heating from charging can be stressful for the entire cooling system. High temperature accelerates the degradation of the electrolyte inside the battery, which leads to a decrease in its maximum capacity after a year of active use.
Also, constant charging at maximum currents puts strain on the motherboard's power controller. If you leave the phone to charge overnight, the power recharge rate becomes secondary, but stability and safety are primary, and current restriction avoids peak loads and reduces the risk of battery bloating in the long run.
⚠️ Warning: Using substandard power supplies or damaged cables when trying to manipulate charge speeds can result in short circuit.
Another important aspect is convenience: some users prefer to charge the device when it is turned off or while working with heavy applications where background charging interferes with the stability of the system. In such cases, forced switching to standard 5B/2A mode is a justified step, which gives full control over the power consumption of the device.
Software Methods through MIUI Settings
The first step for the Xiaomi Redmi 10S owner is to carefully check the standard system settings. Although the direct speed switch is often hidden, there are related features that affect battery behavior. Some versions of MIUI firmware include an option to optimize night charging, which artificially slows the process after reaching 80%.
To access the basic settings, you need to go to the Settings menu and select Battery. Here you should pay attention to the Battery Protection section or similar names depending on the version of the software. Activation of protection functions can indirectly affect the current distribution algorithms, forcing the system to choose a more gentle mode of operation.
It's also worth checking the settings for specific applications. Sometimes the background activity of programs makes the phone warm, which, combined with fast charging, gives critical heating. Turning off background work for unnecessary services will help reduce the overall temperature of the device while connecting to the network.
- 🔋 Go to Settings. → Battery and power-saving mode, which often limits background processes and can reduce charge current.
- 🌙 Activate the Optimized Night Charging feature if it is available in your version MIUI.
- 📱 Check the Settings. → About the phone and make sure the system is updated, as new patches may contain improvements to thermology algorithms.
- 🔌 Turn off vibration when charging to reduce instant power consumption at the start of the process.
It's important to understand that software methods in the standard interface only have a partial effect. Android prioritizes speed when it sees a compatible charger. So, for a deeper intervention, other tools will be required, which will be discussed below. You shouldn't expect the power saving mode alone to completely disable the fast charging protocol.
💡
For maximum effect, combine the power saving mode with the screen off during charging, which will reduce the heat output of the display and processor, allowing the battery to warm less.
Use of Engineering Menu and ADB Teams
For advanced users who are not afraid to work with system code, there is the possibility of influencing charging parameters through USB debugging. This method requires connecting a smartphone to a computer and installing the Android Debug Bridge (ADB) platform. With the command line, you can send signals to the power controller, although in modern versions of Android access to these functions is limited for the sake of security.
Before you start any manipulations, you need to activate the developer mode. → About the phone and seven times quickly click on the build number MIUI. When the message "You became a developer" appears, the corresponding menu will open in the settings. USB».
adb shell dumpsys battery set status 2
adb shell dumpsys battery set level 90These commands are an example of interaction with a battery control system. The dumpsys battery command allows you to emulate different states of charge, which is sometimes used for testing, but does not always force the physical current coming from the network. More effective can be teams that change status USB-Ports, however, vary from model to model.
⚠️ Note: Making changes through ADB-The commands can lead to unstable system operation or cyclical reboot. All actions are performed at your own risk.
There is also an engineering menu available through the code in the call, such as ##6484## (CIT menu).In the Battery test section, you can sometimes find information about the current charging status, but the current control functionality here is usually blocked by the manufacturer. However, real-time monitoring of temperature and voltage will help you understand when the device goes into overheating mode and resets speed.
What if the ADB can’t see the phone?
Physical ways to reduce the charge speed
The most reliable and safe way to turn off fast charging on the Redmi 10S is to use the “wrong” hardware. Rapid charging protocols like Qualcomm Quick Charge or Power Delivery only activate after digital signals are exchanged between the power supply and the smartphone. If you interrupt this dialogue, the device will go to standard 5 Volt mode.
You can use an old 1A or 2A power supply that doesn’t support acceleration technology, or you can use a low-quality cable or a cable that is designed only for charging (without data lines, although it is the signal lines that are needed to activate the QC). If the smartphone does not “agree” with the charger to increase the voltage, it will charge slowly and safely.
Another effective method is the use of USB-port of a computer or laptop. Standard ports USB 2.0 and 3.0 deliver currents of 0.5A and 0.9A, respectively, which are well below the ability to fast charge. This is ideal for nighttime maintenance or long-term storage of the device on.
| Type of food source | Voltage (B) | Current (A) | Charging speed |
|---|---|---|---|
| Original charging Xiaomi | 5-11 (Variable) | Up to 3.0. | Maximum (Quick Charge) |
| Old power supply (5V/1A) | 5 | 1.0 | Slow (Safe) |
| USB port of the computer | 5 | 0.5 - 0.9 | Very slow. |
| Car charging (basic) | 5 | 1.0 - 2.0 | Medium |
Use of special use USB-triggers or crutches» (USB And condom also works. These little devices, inserted between the cable and the phone, lock the data lines, leaving only power. QC/PD Redmi phone 10S physically unable to request increased voltage and will be charged at minimum speed.
☑️ Testing of the physical method
Third-party applications for battery control
There are many apps in the Google Play store and GetApps that promise to manage charging, but it's important to understand the security limitations of Android. Apps without superuser rights (Root) can't directly control the power controller. They can only display statistics or emulate some features.
However, there are utilities that help monitor battery status and warn of overheating. Some can automatically run scripts or change system settings if a device has Root access. For Redmi 10S, obtaining superuser rights will unlock full control, but will take away warranties and may disrupt banking applications.
If you choose to use optimizer apps, choose only proven, high-rated names. Avoid programs that promise to “increase battery capacity” software — this is physically impossible and often a sign of malware. The real benefit of such applications is to analyze the energy consumption of each process in detail.
- 📊 AccuBattery – allows you to track real capacity, wear rate and temperature in real time.
- 🛡️ 3C Battery Manager is a powerful tool for advanced users that requires Root for full functionality.
- 🔋 Battery Charge Limit – an application that can automatically turn off charging when a certain percentage is reached (requires special permissions) ADB).
Using software is a trade-off between functionality and customization complexity. For the average user who just wants to avoid fast charging, physical methods (change power supply) will remain the most efficient and safe, while software solutions are more suitable for enthusiasts willing to experiment with the system.
💡
No application without Root rights will physically prohibit a smartphone to take high current, if it requires the handshake protocol with the charger.
Effect of temperature on the charging process
A key factor that is often ignored is ambient temperature.The Xiaomi Redmi 10S, like any modern device, has built-in protection algorithms.If the battery temperature exceeds a certain threshold (usually around 40-45 degrees Celsius), the MIUI system itself throttling (slows down) charging, even if a powerful power supply is connected.
This means you can “turn off” fast charging simply by ensuring the device is cooled well or, conversely, preventing it from overheating from external sources. Charging the phone under direct sunlight or on a soft surface (sofa, pillow) that covers the heat sink will cause the system to limit current itself, but do so in stress mode.
For optimal mode without fast charging, it is recommended to remove the case during replenishment of energy, if it is dense and poorly conducts heat. Placement of the smartphone on a cool surface, for example, on a tile or a special cooling mat, will allow the battery to take charge more efficiently, even at low currents, without the risk of degradation.
⚠️ Warning: Never put a charging smartphone on heaters or under direct sunlight.The combination of external heat and internal heat from chemical reactions can cause irreversible battery damage.
Understanding the thermodynamics of your device helps extend its life. Fast charging is most aggressive when combined with high temperatures. If you charge your phone in a cool room at night, even using the original charger will be less harmful than during the heat. However, for maximum peace of mind, using a low-power unit remains the best choice.
