How to turn off fast charging on Xiaomi: full instructions for all models

Why do users want to turn off fast charging on Xiaomi?

The fast-charging feature has become standard on most modern smartphones, including the Xiaomi, Redmi and POCO lineups. It allows you to restore battery power to 50-70% in 30-40 minutes, which is undoubtedly convenient in everyday use. However, this technology has a downside: many users notice that when you actively use fast charging, the battery begins to wear out faster, especially after 1-2 years of use.

The main reasons why Xiaomi owners decide to disable this feature are:

• 🔋 Extending battery life – Lithium-ion batteries degrade faster under high charging currents and heating.
• ⚡ Overheating of the device - some models (for example, POCO F3 Redmi Note 10 Pro: Warms up during fast charging.
• 💡 Electricity savings – fast charging consumes more electricity, which can be critical with frequent recharging from powerbank.
• ⚠️ Unstable work is rare, but there are cases when the function is triggered with errors (for example, charging is interrupted by 80%).

It is important to understand that turning off fast charging does not mean a complete abandonment of convenience. You will still be able to charge your smartphone, just the process will be slower, but more careful for the battery. Next we will discuss how to do this on different Xiaomi models and what to consider before changing the settings.

Official method: disabling through MIUI settings

The easiest and safest method is to use the built-in MIUI options, but not all Xiaomi models support this feature out of the box. Below is a universal guide that will suit most devices on MIUI 12/13/14:

1. Open the Settings app (cog icon).
2. Go to the Battery and Performance section.
3. Select Charging or Charging Settings (the name may vary depending on the firmware version).
4. Find the Quick Charge option (sometimes called Turbo Charge or Quick Charge).
5. Move the slider to the off position.

If you don’t have one of these items on your menu, it could mean one of three:

• 📱 Your Xiaomi model does not support software shutdown of fast charging (e.g. budget Redmis). 9A or POCO M3).
• 🔄 You have an outdated version. MIUI (Update the firmware through Settings → The phone. → Updating the system).
• 🔧 The manufacturer has blocked this option for your region (found on global smartphone versions).

Important! After disabling fast charging through the MIUI settings, the smartphone will charge in standard mode (usually 5V/1A or 5V/2A). The charging speed will decrease by about 2-3 times, but this will not affect the functionality of the device.

Alternative methods: hidden settings and engineering menu

If you don't have an option in your standard settings, you can try activating it through an engineering menu or hidden commands, which is suitable for advanced users and requires caution!

Instructions for access to the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636## (some models may not work).
3. In the menu that opens, select Battery Information.
4. Check for the Fast Charge or Quick Charge option.

If the combination doesn’t work, try an alternative way through ADB (requires a PC connection):

adb shell settings put global fast_charge 0

Attention! Changing your settings through the engineering menu or ADB can cause unstable charging or resetting. Use this method only if you are confident in your actions.

Disable fast charging on specific Xiaomi models

Some Xiaomi smartphones have unique features in charge management, and the following is a table with instructions for popular models:

If your model isn’t in the table, try the generic methods from the previous sections. For flagship devices (such as the Xiaomi 13 or Mix 4), advanced charging settings are often available, including limiting the maximum charge level (for example, up to 80% for extending battery life).

💡

On models that support wireless charging (such as the Xiaomi 13 Pro), fast charging is turned off separately for wired and wireless modes. Check both settings in the settings!

What happens if you turn off fast charging: pros and cons

The decision to disable fast charging should be considered.

Advantages:

• ✅ Increased battery life - when charging with low currents, the battery degrades to 20-30% slower.
• ✅ Less heat of the device – especially relevant for gaming smartphones (POCO F3 GT, Black Shark).
• ✅ Stability of operation – excludes voltage surges that can cause sudden reboots.

Disadvantages:

• ❌ Increased charging time instead of 1 hourly 100% may be required 2.5-3 hour.
• ❌ Discomfort in travel – slow charging from powerbank may not keep up with battery consumption.
• ❌ Possible software errors - on some firmware, the shutdown of fast charging leads to malfunctions in the charge sensor.

Tip: If you use fast charging often but want to extend battery life, use adaptive modes (if you have them in your model). For example, on the Xiaomi 12T you can enable the option "Optimized Charging", which automatically limits current after 80%.

💡

Turning off fast charging is advisable if you charge your smartphone overnight or use it sparingly. For active users who care about speed, it is better to leave the function on, but monitor the temperature of the device.

Frequent Mistakes and How to Avoid Them

When trying to turn off fast charging, users often encounter problems, and here are the most common mistakes and ways to solve them:

⚠️ Attention! If after you turn off fast charging, your smartphone stopped charging at all, don't panic. Try resetting through Settings. → System system → Resetting (select Network Reset or Reset All Settings) helps return the standard charging mode in 90% of cases.

• 🔧 Use it. ADB or engineering menu (instructions above).

Error 2: After the switch is off, the smartphone charges even slower than usual.

• 🔌 Check the charger – it may be faulty or not original.
• 📊 Install the AccuBattery app (available on Google Play) to monitor real charging current.
• 🔄 Restart the device – sometimes system processes block normal charging.

Error 3: The fast charging itself turns on after the reboot.

• 📲 This could be a feature of the firmware. Try fixing the settings through ADB:

Additional tips for extending the life of Xiaomi battery

Turning off fast charging is just one way to keep your battery capacity, and here are some more tips to help extend the battery life of your Xiaomi:

• 🔋 Avoid full discharge - try to recharge the smartphone at the level 20-30%, Not waiting for it to turn off.
• ☀️ Do not leave the device in the sun or in a hot place – high temperature accelerates the degradation of lithium-ion batteries.
• 📵 Turn off unnecessary background processes – use the “charge saving” mode in Settings → Battery.
• 🔌 Use original chargers – non-original adapters can deliver unstable voltage.
• 📊 Calibrate the battery - once in a while 2-3 Fully discharge and charge your smartphone for a month 100% for the reset of controller statistics.

To monitor battery status, we recommend installing the AccuBattery app (available on Google Play) that shows real battery capacity, charging/discharge speed and temperature. According to the app's statistics, users who monitor battery health retain up to 80% of capacity after 2 years of use (versus 60-70% for those who ignore the recommendations).

💡

On Xiaomi smartphones that support wireless charging (such as the Mi 11 Ultra or Xiaomi 13 Pro), turn it off in the settings if you don’t use it regularly. Wireless charging heats the device more than wired charging.
