Why does Xiaomi limit charging speed?
Have you noticed that your Xiaomi smartphone has been charging unusually long? Even with the original charger, the process can take several hours. It's not always a breakdown - often the reason lies in the software restrictions that the manufacturer implements to extend the battery life.
Xiaomi is using Adaptive Charging and Battery Protection technology in its devices, which automatically reduce charging speeds under certain conditions, such as high temperatures, long-term network connections, or overnight charging, for example, if you leave your phone on charge all night, the system can limit current to 50-80% to prevent overheating.
But what if you need to charge your device quickly before an important event? Or if the restriction is not working properly? In this article, we will look at all the ways to turn off slow charging on Xiaomi, from simple settings to hidden engineering modes.
Method 1: Disabling Adaptive Charging in Settings
The most obvious and safe method is to deactivate the built-in battery protection features.
- 📱 Open the Settings. → Battery and productivity
- ⚡ Select Charging or Charging Settings (name depends on version) MIUI)
- 🔄 Find Adaptive Charging or Battery Protection options and turn them off
On some models (for example, Redmi Note 12 Pro+ or Xiaomi 13T), these settings may be hidden.
- Go to Settings. → The phone.
- Tap 5-7 times on the MIUI version to activate the developer mode
- Go back to the main settings and open additionally. → For developers
- Find the charging restriction and uncheck the checkbox
Use the original charger
The temperature of the phone does not exceed 35 ° C
Battery level below 80%
The device has the latest version installed. MIUI-->
⚠️ Warning: Disabling battery protection can reduce battery life 10-15% When used intensively, we recommend turning on adaptive charging back if you don't plan to charge the device quickly.
Method 2: Reset charging settings via engineering menu
If standard settings don’t work, try resetting charging options via the engineering menu, which works on most Xiaomi devices, but requires caution.
Instructions:
- Open the phone app and enter the combination: ##4636##
- In the menu that opens, select Battery Information
- Check the current values of charge level and temperature
- Go back to the main engineering menu and select Battery Settings.
- Find the Reset Charging Settings item and confirm the action
Reboot the device after reset, which is especially effective if the slow charging has occurred after a MIUI update or a charger change.
What to do if the engineering menu does not open?
Method 3: Use ADB-team-up
For advanced users, there is a method to disable restrictions through Android Debug Bridge (ADB), which will allow you to manually change charging options that are not available in the standard interface.
Step-by-step:
- Install. ADB-computer-driver
- Enable USB debugging in the developer settings on your phone
- Connect your phone to your PC and execute the command: Adb shell
- Enter sequentially: su echo 1 > /sys/class/power_supply/battery/input_suspend
- To remove restrictions, use: echo 0 > /sys/class/power_supply/battery/input_suspend
⚠️ Attention: Misuse of the right ADB On models with a Snapdragon 8 Gen 2 processor (such as the Xiaomi 13 Ultra), these commands may not work due to hardware limitations.
| Xiaomi model | Support ADB-team | Recommended method |
|---|---|---|
| Redmi Note 10/11 | Yes. | Method 1 or 3 |
| POCO F4/F5 | Partially. | Method 2 + reset |
| Xiaomi 12/13 Pro | No. | Method 4 (firmware) |
| Redmi 9A/9C | Yes. | Method 1 + Cache Cleaning |
Method 4: Install custom firmware (for experienced)
If all the previous methods didn't work, the radical solution is to install an alternative firmware.
- 🔧 LineageOS – pure Android without the limitations of Xiaomi
- ⚡ Pixel Experience – firmware with Google Pixel features
- 🛠️ Xiaomi.EU – modified MIUI China-bound
Installation process:
- Unlock the bootloader through the Mi Unlock Tool
- Install a custom Recovery (TWRP)
- Download the right firmware for your model
- Swipe through the Recovery with a full wipe
⚠️ Attention: Installing custom firmware voids warranty and can lead to a "brick" of the device. RAM (for example, POCO F5 Pro) some firmware may not work smoothly.

Method 5: Hardware solutions (if nothing worked)
If the software methods do not give a result, the problem may lie in:
- 🔌 Faulty charger or cable (check on another device)
- 🔋 Worn-out battery (check out ##6484##)
- 🔌 Contaminated connector USB-C (alcoholize)
- 🔧 Damaged food charge (requires repairs)
To diagnose hardware problems:
- Connect your phone to your PC and check the charging current through AccuBattery.
- If the current is below 1.5A with the original RAM, the problem is in the hardware.
- Try charging your phone in Safe Mode (hold the switch off button → “Reboot Safe Mode”)
💡
To check the actual capacity of the battery, use the application CPU-Z (Battery section). If the actual capacity is less than 80% of the declared, the battery needs to be replaced.
Additional Tips for Accelerating Charging
Even after the limitations are turned off, the charging speed depends on several factors:
- 🌡️ Temperature: optimal range 20-30°C. Pri. 35°C and above charging automatically slows down
- 📴 Mode of use: games and videos during charging reduce speed on the computer 30-40%
- 🔌 Type of charger: Quick Charge-enabled power supply is needed for fast charging 3.0/4.0 or PD 3.0
- 🔋 Battery status: After 500 charging cycles, capacity drops by 20%
For maximum speed:
- Use the original Xiaomi 5A cable
- Turn off your phone or put it in airplane mode.
- Charge at 22-28°C
- Do not use wireless charging – it is always slower than wired charging.
💡
On the new Xiaomi models (13/14 series), Turbo Charging is activated automatically only when using original accessories with support for 120W+.
