Turning off fast charging on the Mi 11 Lite doesn’t require root rights or complex manipulations — just know where to look for the settings you want. In this article, we’ll break down 3 official ways (including hidden MIUI options), talk about the battery implications and give recommendations for safe charging. Importantly, on MIUI versions below 12.5, the path to settings may be different — check the relevance of the firmware in the About Phone section.

Why you should turn off fast charging on Xiaomi Mi 11 Lite

Smartphone makers are pushing fast charging technology but rarely mention the reverse side of the coin. For the Mi 11 Lite with a 4,250mAh battery (in the 5G version) or 4,150mAh (in 4G), the high power charger means:

• 🔥 Overheating of the battery - when charging on 33W Battery temperature can reach 40-45°C, which reduces its resource by 15-20% per year.
• ⚡ Accelerated degradation – Lithium polymer batteries lose up to 3–5% of capacity every 100 cycles during intensive charging.
• 📉 Unstable operation – some users complain of spontaneous reboots when using non-original chargers.

Battery University research shows that the optimal temperature for charging lithium-ion batteries is 10–30°C. When you exceed this threshold, oxidation processes accelerate and capacity drops nonlinearly. If you plan to use the Mi 11 Lite for longer than 2-3 years, turning off fast charging can extend battery life by 30–50%.

Also, fast charging isn’t always justified: for example, if you leave your phone charging overnight, high current in the first hours puts you under too much stress on the battery, and in such cases, it’s best to limit yourself to the standard 5W-10W.

Method 1: Disconnect via MIUI settings (official method)

The easiest and safest way is to use the built-in MIUI options. It is suitable for all versions of the Mi 11 Lite (including 5G and 4G) and does not require additional programs.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Battery and Performance section.
3. Select Charging (in some firmware it may be called Charging Settings).
4. Activate the Regular Charging switch (or Limit the charging power).

After that, the maximum charging power will be reduced to 10W-15W, and the full charging time will increase by about 30-40%. Note: in some regional firmware (for example, for Europe), this item may not be available - then use the second method.

Connect the original charger

Close all background applications

Make sure the battery level is above 20%-->

⚠️ Note: Some custom firmware (e.g. LineageOS or Pixel Experience) may not have this partition, in which case use alternative methods or install official firmware via the Mi Flash Tool.

Method 2: Use of the Battery Savings mode

If your MIUI version doesn’t have a direct option to turn off fast charging, you can bypass the restriction through the power saving mode, which is less efficient (power drops to 12W-18W), but does not require root rights and works on all versions of the Mi 11 Lite.

Algorithm of action:

1. Go to Settings → Battery and Performance.
2. Select Battery Modes (or Energy Saving).
3. Activate Super Energy Saving or Ultra Energy Saving.
4. Connect the charger - the power will automatically be limited.

The downside of this is that it shuts down the background activity of applications and reduces the performance of the processor, but if you need to temporarily reduce battery heat (for example, in the heat or during heavy use), this is the optimal solution.

Method 3: Hidden engineering settings (for power users)

If the first two methods fail, you can use Xiaomi’s engineering menu, which allows you to manually limit the charging current, but you need to be careful – incorrect settings can lead to failures.

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Battery Information.
3. Scroll down and find the AC Charge Limit (or USB Charge Limit).
4. Set the value in the range of 500-1000 mA (this corresponds to 5W-10W).
5. Save the settings and restart the phone.

After the changes are applied, the maximum charging power will be reduced to the specified limit.

• 🔧 Settings may reset after the update MIUI.
• ⚠️ Do not set a value below 300 mA – this can lead to charging errors.
• 📱 Not all versions of the Mi 11 Lite support this menu (depending on regional firmware).

⚠️ Warning: Changing the settings in the engineering menu can lead to unstable operation of the smartphone. If after making changes the phone stopped charging or turns off when connecting charging, return the settings to factory (Reset to Default in the same menu).

How to check if fast charging is actually off

After applying one of the methods, it's important to make sure that the settings work.

1. Connect the Mi 11 Lite to the charger.
2. Open Settings → Battery and Performance → Battery status.
3. Look at the charging schedule – if the power does not exceed 10W-15W, everything is done correctly.

Alternatively, using third-party applications like AccuBattery (available on Google Play) shows the current charging current in real time, normal values after the fast charge is turned off:

• 📊 300-800 mA – standard charging.
• 📊 800-1200 mA – moderately fast (if energy saving mode is used).
• 📊 1500mA and higher – fast charging still active.

If the values are above 1200 mA, repeat the setting or check if the settings reset after the reboot.

💡

If the phone starts charging too slowly (less than 1% per minute) after the fast charge is turned off, try using a Quick Charge 2.0 charger – it automatically adjusts to limited power but provides a more stable current.

What to do if nothing works: alternative solutions

If none of the above methods helped, consider the following options:

• 🔄 Update MIUI — In new firmware versions, additional charging settings may appear. Check the updates in Settings → The phone. → Updating the system.
• 📦 Using another charger – some power supplies (such as from Samsung or Apple) automatically limit power to 5W–10W.
• 🛠️ Custom core installation – requires unlocking the bootloader and root rights, but allows you to flexibly configure charging options (for example, via Kernel Adiutor).
• 🔋 Replacing the battery – if the battery has already degraded (capacity below 80%), fast charging can be dangerous, in which case it is better to replace the battery in the service center.

If you decide to install custom software, note that this will void the warranty and may lead to problems with the Mi Account (for example, locking the device when resetting). Before experimenting, back up the data through Settings → Additional → Backup and Reset.

💡

Turning off fast charging does not guarantee eternal battery life, but reduces the rate of degradation by 30-50%.The optimal strategy is to alternate fast and slow charging (for example, use accelerated mode only when urgently need to recharge).
