How to turn off fast charging on Xiaomi Redmi Note 10: the full guide

Xiaomi Redmi Note 10 is one of the most popular mid-range smartphones, famous for its performance and fast charging. However, not all users know that the constant use of accelerated charging can reduce battery life by 15-20% after 1-2 years of active use. If you notice that the phone warms up a lot during charging or the battery has become discharged faster, you may want to consider turning off fast charging.

In this article, we’ll go through all the ways you can turn off fast charging on the Redmi Note 10 (including the Note 10 Pro, Note 10S and Note 10 Lite models), and explain when you really need it, and learn how to do it through system settings, through the engineering menu, and even physically — without root rights and complex manipulations.

Why you should turn off fast charging on Xiaomi Redmi Note 10

The fast charging technology (on the Redmi Note 10 it’s Fast Charge 33W or Quick Charge 3.0) allows you to charge the battery up to 50% in 30 minutes, but this convenience has the flip side:

• 🔥 Battery overheating – with accelerated charging, the battery temperature can rise to 40–45°C, which adversely affects its chemical composition.
• 📉 Reduced charging cycles – Lithium polymer batteries are designed for 500–800 cycles, and fast charging reduces this number by 20-30%.
• ⚡ Risk of battery bloating – with constant overheating, the probability of battery deformation increases, especially if the phone is charged under load (games, video).
• 💰 Additional load on the power supply – non-original chargers can fail faster when using Fast Charge mode.

Battery University research shows that the optimal temperature for charging lithium-ion batteries is 10–30°C. Exceeding this range by 10°C doubles the rate of battery degradation. If you plan to use the Redmi Note 10 for longer than 2-3 years, turning off fast charging can be a reasonable trade-off between speed and durability.

Method 1: Disconnect via MIUI settings (official method)

The easiest and safest way is to use the built-in MIUI options. Unfortunately, there is no direct switch to turn off fast charging in the standard Redmi Note 10 settings, but there is a workaround through Lean Charging mode:

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Battery and Performance section.
3. Select the Battery Settings item.
4. Activate Lean Charging (or Optimized Charging in newer versions of MIUI).

This mode limits the charging current to 10W, which reduces battery heating, but increases the full charge time to 3-4 hours.

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

If the standard settings do not fit, you can use the engineering menu (Engineer Mode), which is hidden in the MIUI firmware. This method requires caution, since improper actions can lead to malfunctions in the phone.

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that opens, select Battery Information.
3. Click on the three dots in the top right corner and select Battery Settings.
4. Find the Fast Charge and turn it off.

⚠️ Note: On some versions MIUI (Especially global) this item may not be available:

##6484##

Method 3: Disconnect via ADB (for advanced users)

If previous methods have failed, you can use Android Debug Bridge (ADB), a tool for debugging Android devices, which requires connecting the phone to a computer and basic command line knowledge.

Step-by-step:

1. Download and install ADB Tools on PC.
2. Turn on Developer Mode on Redmi Note 10: Go to Settings → About Phone. Click 7 times on MIUI Version until you become a developer!

Settings → Additional → For Developers

USB debugging

adb shell settings put global fast_charge 0

Reset the device.

⚠️ Note: After shutting down fast charging through ADB Some users have noted that the Fast Wireless Charging (if supported) function also stops working:

adb shell settings put global fast_charge 1

💡

Before using ADB, back up your data via Settings → System → Backup. In rare cases, incorrect commands can cause a system to crash.

Method 4: Physical shutdown (using a non-original charger)

If the software methods don't work, you can do a trick, which is to use a charger with less power.

• 📱 Charging from an old smartphone (5W or 10W) — Suitable power supply from iPhone, Samsung Galaxy S5 or other devices with output 5V/1A.
• 🔌 USB-port of the computer - most PCs and laptops give no more current 0.5A–1A, That automatically turns off the fast charging mode.
• ⚡ Power Bank with Current Restriction – Some external batteries (e.g. Xiaomi Mi Power Bank 3) have Low Current mode for gentle charging.

The downside of this method is a significant increase in charging time (up to 5-6 hours for a full cycle), but the battery will heat up minimally, and its life will last 20-30% longer.

Method 5: Disabling fast charging through third-party applications

If you don't want to dig into the settings, you can use the apps from Google Play that control the charging process.

• 🔋 AccuBattery – analyzes the battery status and allows you to limit the charging current to safe values (recommended threshold – 80% for maximum lifespan).
• ⚡ Battery Charge Limit – sets a charging limit (e.g. up to 85%) and reduces the charging speed after reaching this value.
• 📊 GSam Battery Monitor – monitors the battery temperature and automatically reduces current when overheating.

⚠️ Note: Some applications require root rights to work properly; without them, functionality may be limited (for example, AccuBattery will only monitor the charge, but not control it.

💡

The application side cannot completely disable fast charging at the system level, but it helps to control the process and prevent overheating.

What do you do if nothing helps?

If none of these methods worked, the problem may be:

• 🔄 Refresh your old firmware - update it MIUI Up to the latest version through Settings → Updating the system.
• 🔧 Modified firmware - some custom ROM (For example, LineageOS can block access to charging settings.
• 🔌 Faulty Power Controller – If the phone is always charging at top speed regardless of settings, it could indicate a hardware breakdown.

In extreme cases, you can contact the Xiaomi service center to disable fast charging at the firmware level. However, this will require unlocking the bootloader and may deprive you of warranty.

If you decide to leave fast charging, but want to minimize harm, follow these tips:

• 🛌 Do not charge your phone at night (use a timer socket).
• 🌡️ Remove the case while charging for better cooling.
• 🔌 Turn off charging when you reach 80-90% (the optimal level for lithium-ion batteries).
