The Redmi Note 10 S series has powerful 5,000mAh batteries and supports 33W fast charging technology. For many users, this feature is a huge advantage, allowing them to recover a significant portion of the charge in just 30 minutes. However, there are situations where high power recharge speeds become undesirable or even harmful to the device.
Owners often find that the phone gets very hot while charging, especially when used in parallel with the network connection. In such cases, the natural question is: can you forcely limit power or completely turn off accelerated charging? MIUI does not have a single button "Stop Turbo", but there are effective workarounds.
In this article, we will discuss in detail the software and hardware methods of limiting the speed of charge, you will learn how to adjust the battery optimization, which cables to use to reduce power, and why overheating is the main enemy of lithium polymer batteries in the long run.
Why you should limit the speed of charging
Fast charging technology is based on the application of high voltage and current to the battery. Although the power controller in the Xiaomi Redmi Note 10 S strictly regulates this process, physics is physics: high power always generates heat. Overheating is a major factor in the degradation of battery chemistry.
With regular use of maximum charging speeds, especially in high ambient temperatures, the battery capacity starts to decline faster than planned. If you charge your phone overnight, the 33W speed is absolutely redundant, in which case it is much more important to keep the cells healthy than to get a full charge in an hour.
β οΈ Warning: Constant charging at maximum speeds at high temperatures can cause the battery to swell through 12-18 months of active use.
In addition, some users simply prefer a slower, "drop" charging mode, which is considered more gentle for electronics.Power restriction also reduces the load on the power elements of the motherboard, which theoretically increases the overall reliability of the device.
Program Restrictions in MIUI
The Android-based MIUI has a smart power management system, and although there is no direct ban on high current, you can activate functions that indirectly affect this process, and you should focus on optimizing night charging.
To access the settings, go to Settings β Battery β Battery Protection. Here you can find the option βOptimized Charging.β When activated, the system learns your habits and slows down charging after reaching 80%, completing the process only by the time you wake up. This does not turn off the turbo completely, but reduces the time you spend under high voltage.
Another important element is the power saving mode. If you activate the "Energy Saving" mode, the system restricts background activity and can reduce processor performance, which indirectly reduces heating during charging. However, this does not directly block the input current.

Hardware methods of reducing power
The most efficient and reliable way to turn off turbo charging on the Redmi Note 10 S is to use a less powerful charger or cable. Rapid charging protocols like Quick Charge or Xiaomi's proprietary protocol are only activated when handshakes between the charger and the phone.
If you connect your smartphone to a 5W power supply (standard 5V/1A or 5V/2A) or use an old USB 2.0 cable without high current support, the phone will automatically go to normal charging mode.
You can also purchase a special one. USB-trigger or adapter that physically limits the voltage on the line to 5 volts.This ensures that the smartphone power controller will not be able to request increased voltage from the power supply, even if it is powerful on its own.
- π Use the power supply from an old router or button phone (5V/1And).
- π Use Micro-USB cables via an adapter (they often don't support high Type-C currents).
- π Charge the device from USB-port of a computer or TV, where the current is limited by standard (0.5A - 0.9A).

Comparison of energy consumption regimes
Understanding the difference between charging modes will help you choose the optimal strategy. The table below compares performance with the original adapter and the third-party low-power unit.
| Parameter | Original (33W) | Standard USB (5W) | Car charging |
|---|---|---|---|
| Charging time 0-100% | ~60 minutes | ~180 min | ~90 minutes |
| Heating the hull | High-pitched | Minimum | Medium. |
| Impact on Li-Po resource | Average. | Low. | Average. |
| Screen indication | β‘ Turbo Charge | β‘ Charging. | β‘ Charging. |
As the data shows, using a low-power source increases charging time three times, but significantly reduces heat load, and for night use, this is the ideal option to save battery life for years to come.

When buying a new cable, pay attention to its resistance. Cables labeled 5A or 100W will always provoke fast charging, if the power supply allows it.
Third-party applications and automation
For advanced users who want to have full control of the process, there are automation applications, and programs like MacroDroid or Tasker allow you to create scenarios that respond to battery levels.
For example, you can create a macro that, when you reach 80% of the charge, turns on the In-Air mode or shuts down data transmission, which reduces overall power consumption and heating. However, software to prohibit current reception above a certain threshold without root rights is almost impossible due to the limitations of the Android kernel.
There are applications that claim charging, but on non-super-user devices, they are often imitations. They can show beautiful statistics, but they don't have access to a power controller at the Xiaomi driver level.
β οΈ Note: Installing root-right applications for battery management can lead to loss of warranty and disruption of banking applications (SafetyNet/Play Integrity).
