Xiaomi 11T is one of the most popular flagships of the brand, but its fast charging feature (up to 67 watts) is not always useful. Many users face overheating of the device, accelerated battery wear or just want to extend the battery life. In this article, we will discuss all the ways to turn off fast charging on Xiaomi 11T, including hidden MIUI settings, and also tell you what consequences this will entail.
It's important to understand that the manufacturer doesn't always provide a direct option to deactivate fast charging, so some methods require the use of ADB or third-party utilities. We'll look at both the official and alternative options, from simple to advanced. If you're not sure about your technical skills, you'd better limit yourself to standard settings or contact a service center.
This article is relevant for Xiaomi 11T (model 2108119DG) based on MIUI 14/15 and Android 12/13. For other versions of firmware or modifications (for example, 11T Pro), the process may be different - specify the details in the comments.
Why do you need to turn off fast charging on Xiaomi 11T?
Fast charging is a convenient feature, but it has a downside, and here are the key reasons why users prefer to deactivate it:
- 🔥 Overheating of the device: when charging at high power (especially in hot weather), the body temperature can exceed 40°C, which adversely affects the processor and battery.
- 📉 Accelerated battery wear: Lithium-ion batteries degrade faster at high charging currents.Switching off fast charging can extend life on 15-20%.
- ⚡ Unstable power: In regions with frequent voltage surges, fast charging can cause failures or even damage to the power controller.
- 🛌 Night charging: If you leave your phone charging all night, slow charging is safer for the battery.
According to Battery University research, the optimal charging mode for battery durability is a current of no more than 1C (for Xiaomi 11T with a 5000 mAh battery, it is about 5 A). Fast charging exceeds this figure by 2-3 times, which reduces the number of charging cycles.
⚠️ WARNING: If you use a non-original cable or power supply, turning off fast charging is a must! uncertified accessories can cause a short circuit or fire.
Method 1: Disconnect via standard MIUI settings
The easiest method is to use built-in MIUI options. Unfortunately, in the latest versions of Xiaomi 11T firmware, the direct option to turn off fast charging may be hidden, but it can be activated through developer mode.
Follow the instructions:
- Open the Settings. → The phone.
- Find the MIUI version and tap it 7 times until the notification “You’ve become a developer!” appears.
- Return to the main Settings menu and select Additional Settings → Developer Settings.
- Scroll down and find the option to Limit charging current (or Fast charging in English).
- Activate the switch and select 500mA or 1000mA (this simulates slow charging).
If there is no option to Limit Charging Current, try updating your firmware to the latest version or using alternative methods (described below).
Activate Developer Mode | Check version of MIUI| Connect original cable | Charge phone to 30-50% | Make backup of settings-->
Method 2: Use of the ADB-Teams (for experienced users)
If standard settings don’t work, you can use ADB (Android Debug Bridge), which requires connecting your phone to your computer and executing commands via Terminal or PowerShell.
Step-by-step:
- Download and install Platform Tools (includes adb).
- Connect Xiaomi 11T PC-only USB-cable (file transfer mode).
- Open the Command Prompt (Windows) or Terminal (macOS/Linux) in the adb folder.
- Enter the command to check the connection: Adb devices Should appear with the serial number.
- Give permission to debug via USB on your phone (a request will appear).
- Execute the command to disable fast charging: adb shell settings put global battery_charging_limit 1 Here. 1 — limit to 1 A (slow charging).
To return fast charging, use the command:
adb shell settings put global battery_charging_limit 0⚠️ Attention: Misuse of the right ADB It can cause your phone to malfunction. Don't change other settings unless you're sure they're there!
What if the ADB does not recognize the device?
Method 3: Applications for Charging Control
If you don't want to mess with settings or ADB, you can use third-party apps that allow you to flexibly manage charging current, but require root rights or activation of Developer Settings.
Top.-3 apps 11T:
- 📱 AccuBattery – analyzes the state of the battery and allows you to limit the charging current (without root it works in a limited mode).
- ⚡ Battery Charge Limit – sets a charging limit (e.g. up to 80%) and adjusts the speed.
- 🔧 Kernel Adiutor – Advanced Tool for Fine Tuning of the Kernel (Requires Root).
Example of settings in AccuBattery:
- Install the app from Google Play.
- Go to the Charging section → Current restriction.
- Select the value of 1000 mA (or below).
- Activate the option to Apply when connecting charging.
Note: without root rights, apps may run unstable or reset settings after a reboot.
💡
If the charging hasn't slowed down after you install the app, restart your phone. Sometimes the changes only take effect after the reboot.
Method 4: Use of a non-original charger
The most radical but effective method is to use a low-power power supply, such as a charger from an old 5W (5V/1A) smartphone that will automatically limit current.
Suitable options:
| The device | Power | Charging current | Note |
|---|---|---|---|
| Charging from iPhone (5W) | 5W | 1A | Completely disables fast charging |
| Charging from Samsung (10W) | 10W | 2A | Charging is slower but not completely limited |
| USB-port | 2.5W-5W | 0.5A-1A | The safest but slowest option |
| Wireless charging (Qi) | 5W-10W | 1A-2A | Automatically restricts current |
The downside is that you have to use a separate charger all the time, and some power supplies may not be recognized by the phone and charging won't start at all.
⚠️ Attention: Using cheap uncertified chargers is dangerous! they can damage the power controller or cause a fire. USB-IF Qualcomm Quick Charge.
What happens if you turn off fast charging: pros and cons
Before you make a decision, evaluate the consequences.We have collected the key pros and cons of turning off fast charging on the Xiaomi 11T:
| Pluses | Cons |
|---|---|
| ✅ Extension of battery life by 15-30% | ❌ Increased charging time with 30-40 min 2-3 hours |
| ✅ Reduced phone heat during charging | ❌ Possible malfunctions of some applications (if used) ADB) |
| ✅ Safety when using non-original cables | ❌ Need for manual control (if applications are used) |
| ✅ Less wear on the connector USB-C (low-current) | ❌ The risk of loss of warranty (if root is used) |
Critical: If you have disabled fast charging via ADB or root, some system updates may reset. After upgrading MIUI, check the settings again!
Also note that on the Xiaomi 11T with MIUI 14+ firmware, some methods (e.g., changing parameters via engineering mode) may be blocked by the manufacturer.
Frequent Mistakes and How to Avoid Them
When you turn off fast charging, users often encounter problems, and here are the most common mistakes and ways to solve them:
- 🔌 The phone doesn't charge after the change: check the cable and the power supply. ADB, Adb shell settings put global settings battery_charging_limit 0 discharged.
- 📱 Settings are reset after rebooting: this is normal for methods without root. Use automation (e.g. Tasker) to apply limitations when connecting charging.
- ⚡ Charging is too slow: if you use a power supply 5W, For acceleration (but not to maximum), select the charger on the 10W-18W.
- 🔥 The phone warms even after you turn off fast charging: check background processes (such as games or updates) or clear the cache in Settings → Memory.
If neither method worked, your version of MIUI may have severe limitations, and there are two options left:
- Update the firmware to the latest version (sometimes new builds add flexibility in settings).
- Install custom firmware (such as LineageOS or Pixel Experience) where charging control is better implemented.
💡
On Xiaomi 11T with MIUI 15, disabling fast charging through standard settings may not be available, in which case ADB or third-party apps are the only working options.
