But before we get to the instructions, it's important to understand that turning off fast charging isn't always safe. The manufacturer adjusts the charging algorithms to the battery, and interfering with them can have unexpected consequences. We'll look at the risks, the alternatives, and we'll checklist the safe experiment.

If you choose to do this, follow the instructions carefully. Some methods require unlocking the bootloader or the superuser's rights, which automatically disqualifies warranty. Also remember: after disabling the turbocharging, the full charging time can increase from 50-60 minutes to 2-3 hours depending on the adapter used.

At the end of the article, you'll find the FAQ, which answers frequent questions, a method comparison table, and tips for extending battery life without drastic measures, starting with the simplest way, through standard MIUI settings.

1. disable turbocharging via MIUI settings (official method)

The safest and most recommended way is to use the built-in options. Unfortunately, there is no direct "Disable Fast Charging" button in the Poco F3, but you can activate the "Optimized Charging" mode, which limits power to 10W after 80% charge. This is not a complete shutdown, but a partial solution.

To enable this regime:

1. Open Settings → Battery and Performance.
2. Put it on the icon. ⚙️ (gear) in upper right corner.
3. Select Battery Settings → Optimized Charging.
4. Activate the switch and set the start time for charging (for example, overnight).

This method has several limitations:

• 🔋 Fast charging works up to 80%, then goes into gentle mode.
• ⏱️ Full charging takes longer, but not as radically as when you’re completely offline.
• 🔄 Mode resets after rebooting or resetting settings.

If you don't like a partial restriction, read on. The next method will require access to an engineering menu that is hidden from ordinary users.

2.Use of the engineering menu (hidden settings)

The engineering menu (#4636##) allows you to change the charging settings, but it requires caution. Incorrect settings can cause failures or even battery failure. Before you start, make sure that the battery is charged by 30-70%, which will reduce the risk of errors.

Instructions for disconnecting turbocharging:

1. Open the Phone app and enter the combination ##4636##.
2. In the menu that opens, select Battery Information.
3. Scroll down to the Fast Charge Config section (can be called Fast Charging or Quick Charge).
4. Select the value and select Disable or Off.
5. Save the changes and restart the device.

Important nuances:

• 🛠️ On some firmware MIUI This item may be missing or blocked.
• 🔄 After updating the system, the settings may reset.
• ⚠️ Do not change other options in the engineering menu – this can disrupt the stability of the smartphone.

If the engineering menu doesn't allow you to turn off turbocharging, you'll have to use more advanced methods, and one of them is ADB commands, which allow you to intervene more deeply into the system.

💡

Before working with the engineering menu, back up your data via Settings → System → Backup. This will help you restore your settings if something goes wrong.

3. Disable fast charging via ADB (for advanced users)

The Android Debug Bridge (ADB) method requires connecting the smartphone to a computer and executing commands through the terminal, a more reliable way than an engineering menu, but also carries risks, and the wrong command can cause the system to crash or block charging altogether.

What you'll need:

• 💻 A computer with installed Xiaomi drivers and ADB (You can download from the official Android website).
• 🔌 USB-cable (preferably original).
• ⚙️ Included debugging by USB (Settings → The phone. → Version. MIUI → Tap 7 times on the version, then go back to Settings → Additionally. → For developers → Debugging by USB).

Step-by-step:

1. Connect Poco F3 to your computer and confirm the debugging permission on your smartphone screen.
2. Open the command prompt (cmd on Windows or Terminal on macOS/Linux) in the folder with ADB.
3. Enter the command to check the connection: Adb devices must appear serial number of your device.
4. Execute the command to disable fast charging: adb shell settings put global fast_charge 0
5. Reboot your smartphone.

To return the turbocharger, use the same command, replacing 0 by 1.

Warning: Some users report that after this method, charging may not work smoothly – for example, periodically shut down or show errors. If this happens, try resetting the settings via ADB:

adb shell settings delete global fast_charge

4. Alternative methods: limiting the power of the charger

If the software methods don't work or seem too risky, the other way to do this is to physically limit the charging power, and it won't turn off turbocharging at the smartphone level, but it will make it charge more slowly.

Methods of power limitation:

• 🔌 Use a charger with power 5W or 10W (For example, from an old iPhone or Samsung. F3 automatically adjust to available power.
• 🔄 Connecting the smartphone through USB-hub USB 2.0 is usually not more than that. 2.5W.
• 🔋 Use power bank with limited current (some models have a low power mode").

Advantages of this method:

• ✅ No need to interfere with the system.
• ✅ Safe for battery (if you use a certified RAM).
• ✅ It is easy to return the turbocharger – just connect the original adapter.

Disadvantages:

• ❌ Charging takes in 2-3 time (up to) 4-5 hours).
• ❌ Some adapters may not be recognized by the system and charging will not start.

This is ideal for those who want to save the battery but are not willing to risk the stability of the system, such as using a weak charger at night and the original 33W adapter during the day.

5. Risks and consequences of disabling turbocharging

Before you make a decision, weigh the pros and cons. Disabling fast charging affects not only speed, but also other aspects of the smartphone.

Possible problems:

• ⚡ Increased charging time with 1 hourly 3-4 hours (depending on the adapter).
• 🔥 Overheating when using uncertified RAM – the smartphone may not recognize power limitations.
• 📉 Decreased performance during charging (if you disable turboreg via the engineering menu, the system may limit the clock speed of the processor).
• 🔄 Unstable work – some users complain of spontaneous reboots after changes in the ADB.

The benefits of shutdown:

• ✅ Extension of battery life by 15-20% (According to Battery University research, slow charging reduces the degradation of lithium-ion batteries).
• ✅ Less heating of the device during charging (relevant for gamers and those who use the phone while recharging).
• ✅ Safety – reduces the risk of battery bloating when using low-quality adapters.

Critical information: If you have turned off turbocharging via ADB or engineering menu, but the smartphone stopped charging at all, reset the settings via fastboot (instruction below).

This command will reset all user settings, but will save the data in the phone’s memory.

6.How to return turbocharging after disconnection

If you've been experimenting with settings and want to get back to factory settings, use one of the methods below. Importantly, after some changes (e.g. through ADB), you may need to reset completely.

Methods of recovery of fast charging:

If neither method worked, the problem may be the firmware, which can be done by flashing through the Mi Flash Tool (you can find instructions on the XDA Developers or 4PDA forums).

⚠️ Attention: if after manipulation with charging the smartphone began to quickly discharge or turn off on 20-30% A charge is a sign of battery damage. Don't try to treat it software-based: contact a service center for a diagnosis.

7. Alternative solutions: how to save the battery without turning off turbocharging

Turning off fast charging isn’t the only way to extend the life of a battery, but here are some proven recommendations to help keep the battery pack pack packing without drastic measures:

Tips for battery care:

• 🔋 Avoid deep discharge (below). 10%) and full charge (above) 90%). Optimal range — 20-80%.
• 🌡️ Do not use your phone in extreme temperatures (below 0)°C or higher than 35°C).
• 🔌 Turn off charging after reaching 80-85% (You can use automatic shutdown via Tasker or MacroDroid).
• 📵 Avoid wireless charging – it heats the battery more than wired charging.
• 🔄 Once 2-3 Calibrate the battery for a month: discharge the phone before 0% and charge up 100% breaklessly.

Applications for battery monitoring:

• AccuBattery – tracks charging cycles and makes recommendations.
• GSam Battery Monitor – shows which applications use the most power.
• Battery Guru analyzes battery health and temperature.

If you do decide to turn off turbocharging, combine this with other battery care measures, such as using a weak adapter at night and the original one during the day, and monitoring the temperature of the device.

💡

Turning off turbocharging extends the life of the battery, but it does not guarantee its eternal operation, the main thing is to avoid extreme loads and monitor the temperature regime.
