How to disable fast charging on Android: a complete guide for all brands

Fast charging has become a standard feature of most modern smartphones on Android, but it does not always benefit the device. Many users are faced with the fact that the battery heats up too much, wears out quickly, or the phone begins to “slow down” while charging. In some cases, disabling fast charging can even extend battery life 20-30%, especially if you use non-original chargers.

In this article we will look at all the possible ways to disable fast charging - from standard settings in the smartphone menu to hidden engineering modes and third-party applications. You will learn how to do this on Samsung Galaxy, Xiaomi/Redmi, Honor/Huawei, Realme/Oppo and other popular brands. We will also explain in which cases this is really necessary, and when it is better to leave the function enabled.

Important: the procedure may differ depending on the version Android and shell of the manufacturer. If your smartphone model was released before 2020, some methods may not work - in such cases you will need to use alternative solutions.

Why should you disable fast charging?

Before moving on to the instructions, let's take a look at in what situations disabling fast charging is really justified. Fast charging works by increasing current and voltage, which leads to:

• 🔥 Battery overheating — the battery temperature can rise to 45-50°C, which reduces its resource.
• 📉 Accelerated wear —lithium-ion batteries lose up to 20% of their capacity after 300-500 fast charging cycles charging (versus 800-1000 cycles with standard).
• ⚡ Unstable operation —some smartphones begin to “lag” or spontaneously reboot while charging.
• 💸 Increased energy consumption —fast charging can increase electricity bills by 10-15% with regular use.

However, there is a downside: if you are often on the road and need to quickly restore charge, disabling the function may create inconvenience. In this case, we recommend using hybrid approach: turn off fast charging at night or when the phone has been on charge for a long time, and turn it on only when necessary.

⚠️ Attention: On some models Samsung and Xiaomi disabling fast charging can lead to to the fact that the phone will charge extremely slowly (less than 1% per minute) when using powerful adapters. In this case, you will have to use an original 5W charger.

Method 1: Disabling through standard Android settings

The easiest method is to use the built-in system options. Unfortunately, not all manufacturers provide this feature out of the box, but the function is available on most modern smartphones. Let's look at how to do this on different brands.

For smartphones Xiaomi, Redmi i POCO

1. Open the application Settings.

2. Go to the section Battery and performance (on some models - Battery).

3. Select Battery settings → Mode charging.

4. Turn off the switch Fast charging (or Turbo Charge on new models).

For smartphones Samsung Galaxy (One UI)

1. data-i="80">Settings Settings → Device care → Battery.

2. Click on the three dots in the upper right corner and select Settings.

3 Find the option Fast charging (or Super Fast Charging) and deactivate it.

For smartphones Honor and Huawei (EMUI/Magic UI)

Open Settings → Battery.

2. Go to More (or Additional).

3. Disable Fast charging or Huawei SuperCharge.

If there is no such option in your menu, it means that the manufacturer has blocked the ability to disable it through the standard interface. In this case, you will have to use alternative methods described below.

⚠️ Attention: On some models Realme And Oppo (ColorOS) disabling fast charging may result in the phone being charged only from the original charger. Third-party adapters may not be recognized.

Check the current battery temperature in the settings

Connect the original charger (if available)

Close all background applications

Make a backup copy of important data (in case of failure)-->

Method 2: Using the engineering menu (for advanced users)

If there is no option to disable fast charging in the standard settings, you can try to do this via engineering menu. This method is suitable for most smartphones based on Qualcomm Snapdragon or Mediatek, but requires caution - incorrect actions can lead to malfunctions of the device.

Instructions for Qualcomm:

1. Open the application Phone.
2. Enter the code ##4636## (may be required for some models ##36446337##).
3. Select Battery information.
4. Find the setting Fast Charge or Quick Charge and turn it off.

Instructions for Mediatek:

1. Install the application MTK Engineering Mode from Google Play (if it is not available, download the APK from a trusted source).
2. Open the application and go to the section Hardware Testing → Charging.
3. Disable options Fast Charging and Pump Express.

If the engineering menu is missing or the parameters are inactive, this may mean that the manufacturer has blocked access to these settings. In this case, only rooting (obtaining root access) or using ADB commands will help.

What to do if the engineering menu does not open?

If nothing happens after entering the code, try the following options:

1. Use an alternative code: #15963# (for some Samsung) or ##2846579## (for Huawei).

2. Install the application Shortcut Master and find hidden settings through it.

3. Check if the manufacturer has blocked the engineering menu in the latest firmware updates. In this case, only rooting will help.

Method 3: Disabling via ADB (without root access)

If standard methods do not work, you can use Android Debug Bridge (ADB) a debugging tool that allows you to change hidden system settings without obtaining root access. This method is suitable for most smartphones, but requires connecting to a computer.

Step-by-step guide:

1. Download and install ADB Tools on your computer (for example, Minimal ADB and Fastboot).
2. Enable on your smartphone Mode Developer (click on Build number 7 times in the phone settings).
3. Activate USB debugging in the developer menu.
4. Connect your phone to the PC and enter in the command line:

   adb shell settings put global fast_charge 0

5. Reboot the device.

To return fast charging, use the command:

adb shell settings put global fast_charge 1

If the command did not work, try the alternative:

adb shell settings put global battery_charging_limit 0

(this will disable all charging restrictions, including fast charging).

⚠️ Attention: On some smartphones Xiaomi and Samsung after using ADB, protection may work Knox, which will reset the security certificate. This does not affect the operation of the phone, but may block access to some functions (for example, Samsung Pay or Secure Folder).

Method 4: Applications for charging control

If you don’t want to mess with settings or ADB, you can use third-party applications. They do not always give 100% results, but in most cases they help limit the charging current or completely disable fast protocols.

Top 3 tested applications:

• 📱 AccuBattery - shows the current charging current and allows you to set a limit (requires root for full control).
• ⚡ Battery Charge Limit - limits the maximum charge level (for example, to 80%), which indirectly reduces the charging speed.
• 🔧 Quick Charge Switch - specialized application for disabling Qualcomm Quick Charge (does not work on all models).

How to use AccuBattery:

1. Install the application from Google Play.
2. Go to the tab Charging.
3. Click on the icon ⚡ in the upper right corner.
4. Select Limit charging current and set the value no higher than 1000 mA (1A).

Please note: without root, applications can only recommend restrictions, but do not guarantee their implementation. Rooting will be required for full control.

Application	Requires root	Efficiency	Supported brands
AccuBattery	No (partially)	Average	All
Battery Charge Limit	Yes	High	Samsung, Xiaomi, Huawei
Quick Charge Switch	No	Low	Qualcomm devices
Kernel Adiutor	Yes	High	All (requires a custom kernel)

Method 5: Physical limitation (using a weak charger)

If software methods do not help or you do not want to risk the phone settings, you can go another way - use a charger with low powerMost smartphones automatically switch to standard charging mode if the connected adapter does not support fast charging. protocols.

What chargers are suitable:

• 🔌 Standard USB port of a computer or laptop (0.5A - 1A).
• 📱 Charging from an old smartphone (for example Nokia or Sony Ericsson with an output of 5V/0.7A).
• ⚡ Non-original adapters with a power of up to 5W (5V/1A).
• 🔋 Power Bank with an output of 5V/1A (many modern power banks support fast charging, so check the characteristics).

How to check the current charging power:

1. Install the application Ampere or AccuBattery.

2. Connect the charger.

3. charging current (in mA). If the value exceeds 1000-1500 mA, then a fast protocol is used.

⚠️ Attention: Using low-quality chargers can lead to battery damage or even fire. Buy adapters only from trusted brands! (Anker, Baseus, Xiaomi) and avoid “no-name” products.

💡

The safest way to disable fast charging is to use an original 5W (5V/1A) charger. This is guaranteed. will switch the phone to standard mode without risk to the system.

What to do if nothing helps?

If none of the above methods worked, there are two radical options left:

1. Rooting a smartphone — obtaining root access allows you to edit system files responsible for charging. For example, you can disable fast charging by changing the settings. in the file /sys/class/power_supply/battery/input_current_max. However, this voids the warranty can lead to unstable operation of the device.
2. Installing custom firmware - some alternative firmware (for example, LineageOS or Pixel Experience) allow you to flexibly configure charging parameters. But this method is only suitable for experienced users.

Before resorting to such measures, assess the risks:

• 🚫 Loss of warranty (if the phone is under warranty).
• 🔄 Possible malfunctions in the system.
• 🛠️ Difficulty of rolling back to standard firmware.

If you decide to root, use proven tools:

• For Samsung — Magisk + TWRP.
• For Xiaomi — OrangeFox Recovery.
• For Google Pixel is the official bootloader unlocker.

⚠️ Attention: On some models Huawei and Honor rutting can block access to banking applications and services Huawei Mobile Services.

FAQ: Frequently asked questions about disabling fast charging

❓ Is it possible to disable fast charging only at night?

Yes, use the application for this AccuBattery or Battery Charge Limit. Set a time limit (for example, from 23:00 to 7:00) or by charge level (for example, up to 80%). You can also use automation via Tasker or MacroDroidfast charging on a schedule.

❓ Why did the phone charge even slower after turning off fast charging?

This can happen for two reasons:

1. You are using a non-original charger with low current (less 0.5A). Try connecting the phone to the USB port of the computer or use a 5V/1A adapter.
2. The manufacturer has blocked the standard charging mode for uncertified adapters. In this case, only an original charger will help.

❓ Is fast charging harmful to the battery?

Yes, but not critical. Fast charging increases the load on the battery, which reduces its capacity over time. However, modern smartphones have built-in protection mechanisms:

• 🔋 Current limitation when reaching 80-90% charge.
• 🌡️ Automatic power reduction when overheating.
• 🔄 Optimization of charging cycles (for example, Adaptive Charging on Google Pixel).

If you use an original charger and do not leave the phone on charge all night, the harm will be minimal.

❓ How to check if fast charging?

There are several ways:

1. Use the application Ampere - if the charging current does not exceed 1000-1500 mA, fast charging is disabled.
2. Look at the charging indicator - on some smartphones (Xiaomi, Samsung) the corresponding icon is displayed when fast charging.
3. Note the charging time from 0 to 100%: if it increases by 1.5-2 times, then the function is disabled.

❓ Is it possible to disable fast charging on an iPhone?

No, iPhone there is no built-in option to disable fast charging. However, you can:

• Use a 5W charger (standard “charging cube” from Apple).
• Enable mode Optimized battery charging in settings (Settings → Battery → Battery status).

Starting from iOS 13, Apple automatically limits charging to 80% when connected to the network for a long time, which partially compensates for the lack of manual control.
