How to turn off fast charging on Xiaomi Redmi Note 10S: all ways

The fast charging feature in the Xiaomi Redmi Note 10S is a convenient solution for those who are used to recharge the battery in minutes. However, not all users appreciate this technology. Rapid charging accelerates battery wear, heats the device and can reduce its life by 15-20% during heavy use. If you notice that the smartphone overheats during charging or the battery began to go down too quickly, turning off this feature can be a reasonable tradeoff between speed and durability.

In this article, we’ll look at all the ways you can turn off fast charging on the Redmi Note 10S, from standard settings to hidden features in the engineering menu, how to temporarily or permanently deactivate accelerated charging, what alternatives exist to take care of the battery, and what to do if the option is not displayed on the menu, and we’ll analyze how much life can be extended by not fast charging, and what other factors affect its wear.

Why you should turn off fast charging on the Redmi Note 10S

The Redmi Note 10S’ Quick Charge 3.0 technology allows you to charge up to 50% of your battery in just 30 minutes. But it costs a lot to charge: High current and 9V/2A or 12V/1.5A put additional strain on lithium-ion cells. Studies show that regular use of fast charging can:

• 🔥 Increase the battery temperature to 40-45°C, which accelerates the degradation of the electrolyte.
• 📉 Reduce battery capacity by 10-15% after 300-400 charging cycles (versus 500-600 for standard charging).
• ⚡ Increase the risk of sudden shutdown at low charge due to uneven cell wear.

This is especially important for users who:

• 📱 Charge your smartphone at night (prolonged stay at 100% at high temperature worsens the battery).
• 🌡️ Operate the device in hot climates or under direct sunlight.
• 🔄 Often discharge the phone to 0% before charging.

⚠️ Warning: If you use a non-original power supply or cable, the risk of overheating and battery damage increases by 2-3 times.

Method 1: Disconnection through standard settings

The easiest and safest method is to use built-in MIUI options. Depending on the firmware version, the path to settings may vary slightly, but the general logic remains:

1. Open the Settings app (cog icon).
2. Go to the Battery and Performance section.
3. Select the Battery Settings item.
4. Find the Quick Charge option (or Quick Charge) and move the slider to the Off position.

If there is no option, check:

• 📱 Version MIUI — in old firmware (below) MIUI 12.5) the function may have been hidden.
• 🔌 Type of charger – some power supplies do not support power adjustment.
• 🔄 System Updates – Installing the latest version of the software can return the option.

Check the version of MIUI in Settings → About the phone

Connect the original charger

Make sure the battery level is above 20%

Reboot your smartphone before changing your settings-->

After the shutdown, the smartphone will be charged at standard power (5V/2A), which will increase the charging time to 2-2.5 hours, but reduce the load on the battery.

Method 2: Use of an engineering menu (for power users)

If the fast charging option is not available in the standard settings, it can be disabled via the Engineering Mode, a method that requires caution, as incorrect changes can cause the device to malfunction.

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Battery Information.
3. Scroll down and find the Fast Charge or Quick Charge.
4. Click on it and select Disable.
5. Reboot your smartphone to apply the changes.

⚠️ Note: In some versions MIUI The engineering menu can be blocked. If nothing happens after you enter the code, try using the app. MTK Engineering Mode (available on Google Play for MediaTek-based devices with Redmi Note) 10S).

After you turn off fast charging through the engineering menu, it is recommended to check the actual charging power using applications like AccuBattery or Ampere. They will show the current current and voltage values to make sure that the changes have taken effect.

Method 3: Applications for Charging Control

If standard methods don't work, you can use third-party utilities, which don't turn off fast charging at the hardware level, but they limit charging current by simulating standard mode.

For use of AccuBattery:

1. Install the app from Google Play.
2. Go to the Charging section.
3. Activate the option to Limit the charge to 80% (Charge to 80%).
4. Connect the charger – the application will automatically stop charging when it reaches the threshold.

This method doesn’t turn off fast charging completely, but it reduces battery loads by preventing overcharging and overheating, especially for those who leave their smartphone on overnight charging.

All the time, it saves time.

What to do if fast charging does not turn off

Sometimes, even after all the manipulations, the smartphone continues to charge in an accelerated mode.

• 🔌 Non-original charger - some power supplies ignore the phone's settings and deliver maximum power.Solution: use only the original Xiaomi adapter (model) MDY-12-ED For the Redmi Note 10S).
• 📲 Firmware failure - after updating the system, the settings may reset. Solution: perform the reset to factory settings (Settings) → The phone. → Resetting settings).
• 🛠️ The connector is damaged. USB-C — oxidation or contamination of contacts can lead to incorrect identification of the type of charging.

If the problem persists, check the actual charging power with the Ampere app:

1. Install Ampere from Google Play.
2. Connect the charger.
3. Run the app and see the current current (mA) values.
4. If the current exceeds 1000-1200 mA, the fast charging is still active.

💡

If your smartphone is warming even when you turn off fast charging, try charging it in airplane mode or with the screen off, which will reduce the load on the processor and reduce heat generation.

How to check if fast charging is actually off

To make sure that the changes are effective, use one of the following methods:

1. Charging time: When fast charging, the Redmi Note 10S gains 50% in ~30 minutes. When charging standard (5V/2A), this time increases to 60-90 minutes.
2. Body temperature: Fast charging heats the smartphone to 40–45°C (tangibly warm). Standard charging keeps the temperature within 30–35°C (smallly noticeable heat).
3. Monitoring applications: AccuBattery will show the current charging rate in mAh/h. Ampere will display current (mA) and voltage (V).

For accurate diagnosis:

1. Connect your smartphone to the charger.
2. Launch AccuBattery and go to Charge tab.
3. Note the graph – if the charging speed exceeds 2000-2500 mAh / h, fast charging is still active.

⚠️ Attention: Some applications (e.g, CPU-Z) It shows supported charging technologies (Quick Charge 3.0), but that doesn't mean it's active at the moment.

Alternative ways to treat the battery with care

Turning off fast charging is just one step to extending battery life. To maximize the capacity of the Redmi Note 10S battery, follow these guidelines:

• 🔋 Avoid full discharge – recharge your smartphone at 20-30%, preventing a drop to 0%.
• 🌡️ Control the temperature – do not use your phone in the sun or near heat sources (e.g., on a car torpedo in summer).
• 📵 Turn off unnecessary functions while charging: Wi-Fi, Bluetooth, GPS background applications.
• 🔄 Update the firmware - in new versions MIUI Often optimized algorithms for food management.
• 🛌 Don’t leave it on overnight charging – use smart timer outlets or apps like AccuBattery to automatically shut down.

Also, you should pay attention to the calibration of the battery: If the smartphone suddenly turns off at 15-20% charge or shows an incorrect percentage, follow the procedure:

1. Discharge the phone before automatically shutting down.
2. Connect to the charger and wait 100% (do not turn on!).
3. Turn off the charging, turn on the smartphone and again wait for full discharge.
4. Repeat the cycle 2-3 times.

💡

Optimal charging mode for battery durability: keep your charge level in the range of 30-80%, avoid extreme temperatures and use original accessories.
