How to remove the speed limit on the phone Xiaomi: all working methods

Have you noticed that your Xiaomi mobile internet is slower than it should be? or that after the MIUI update, Wi-Fi suddenly dropped by a factor of 2-3? The reason may lie in hidden system settings that artificially limit network bandwidth. The manufacturer often sets such limits to save battery power or "optimize" traffic, but for the user this means eternal video buffering, slow download of files and lags in online games.

In this article, we’ll look at 5 proven ways to disable the network speed limit on Xiaomi, Redmi and POCO smartphones, from standard MIUI settings to hidden engineering menus. All methods run on current firmware versions (including MIUI 14/15 and HyperOS) and do not require superuser rights. Importantly, some options may differ depending on the model and regional firmware, but the general logic remains the same.

Why does Xiaomi limit network speed?

The manufacturer never officially admits that artificial restrictions exist, but firmware analysis and user tests confirm their existence, and here are the main reasons why your Xiaomi can strangle the Internet:

• 🔋 Battery savings: MIUI By default, it activates energy saving mode for mobile data, reducing the background speed by 30-50%, which is noticeable when downloading files in the background (for example, application updates).
• 📶 Adaptive Network Optimization: Algorithms MIUI They analyze the quality of the signal, and when the coverage is weak, they automatically slow down the speed to avoid communication interruptions.
• 🌍 Regional restrictions: Some firmware for Russia and CIS artificially lowered modulation parameters 4G (for example, instead 256-QAM used 64-QAM), Reduces the maximum speed by 20 to 40%.
• 🔄 Errors after updates: Often after major updates MIUI Network settings are reset and the system goes into "safe mode" at a limited speed.

How do you check if the speed is really limited? Run a Speedtest or nPerf test, then restart the phone in Safe Mode (press the power button → Reboot Safe Mode) and if the speed is higher in Safe Mode, the problem is exactly in the MIUI settings.

Method 1: Disabling energy saving for mobile data

The most common reason for slow internet is the background traffic restriction, which MIUI turns on by default, to turn it off:

1. Open the settings → Battery and performance.
2. Go to Battery Settings → Energy Saving Modes.
3. Select Performance mode (if not, turn on Adaptive Mode and turn off the option to Limit Background Activity).
4. Return to the main settings menu and open Connections and Sharing → Mobile Network → Data Transfer.
5. Activate the switch Allow data to be used in the background for everyone SIM-map.

Then check the speed again. If you don't get any improvement, move on to the next method.

Charge Savings mode is disabled"|Performance mode activated"|Background data transmission is permitted|Rebooted phone-->

⚠️ Note: On some models (Xiaomi) 12T, Redmi Note 11 Pro+) If you have a power cut, you can increase your battery consumption by 10 to 15 percent. If you have a critical battery life, use adaptive mode and manually add your frequently used apps (YouTube, Telegram, games) to your exclusion list.

Method 2: Reset APN settings (Access Points)

Incorrect parameters APN — The second most common cause of slow Internet, especially after a shift. SIM-I'm going to have a map or firmware update:

1. Go to Settings → Connections and Sharing → Mobile Network.
2. Choose yours. SIM-card (if there are several).
3. Press Access Point Names (APNs).
4. In the upper right corner, tap three points and select Reset to default values.
5. If the reset didn’t help, create a new APN manually (request options from the operator or find them on their website).

For MegaFon, Beeline and MTS, the current APN settings (2026) are shown in the table below. If your operator is not on the list, use automatic settings via SMS (send an empty message to 0880 for MTS, 5049 for Beeline, 5050 for MegaFon).

Critical detail: after changing the APN, be sure to restart the phone and turn flight mode on/off. In 30% of cases, the new settings are applied only after the communication module is fully restarted.

Method 3: Engineering menu to unlock full 4G/5G speed

If previous methods have failed, you will have to turn to the hidden settings of the communication module, which requires caution, but gives maximum effect - especially on older models (Xiaomi Mi 9, Redmi Note 8 Pro), where MIUI limits speeds to 150 Mbps instead of the possible 300-600 Mbps.

Instructions for MTK-chips (e.g. Redmi) 9A, POCO M3):

1. Open the phone app and enter the combination: ##4636##
2. In the menu that opens, select Phone Information.
3. Scroll down to the Network Type Installation block.
4. Select LTE only (if you only need 4G) or NR/LTE (for 5G).
5. Go back and go to Settings → Connections → Mobile Network → Network Type, then select 4G Only (preferably) or 5G/4G/3G.

Instructions for Snapdragon chips (Xiaomi 11T, Redmi K50):

1. Enter the phone app: ##2263###
2. Select Band Selection (Frequency Selection).
3. Mark all available ranges (especially B1, B3, B7, B20 for Russia).
4. Save the settings and restart the phone.

⚠️ Warning: Sloppy changes to the engineering menu may result in network loss or inability to make calls. If the signal is lost after the changes, reset the network settings to Settings → System system → Resetting settings → Resetting Wi-Fi, Mobile Network and Bluetooth.

Method 4: Disabling Smart Optimization in MIUI Lab

MIUI hides a number of features in the system’s lab where you can turn off automatic speed limits, a technique that works on most models, including the Xiaomi 13, Redmi Note 12 and POCO F5:

1. Open the Settings. → The phone.
2. Tap 5-7 times on the MIUI version until the message “You are a developer!” appears.
3. Return to the main settings menu and open Additional → Developer options.
4. Activate the switch Enable the developer settings (if it is turned off).
5. Find and disable options: Limit background processes → Select Standard Limit. Optimize MIUI (may be called Smart Optimization) Limit loading speed in the background.

Reboot the phone.

Then check the speed through Fast.com (Netflix, which shows real speed without caching), and if the value has increased by 30% or more, the optimization has worked.

💡

If after optimizing the phone started to warm or discharge quickly, return the settings back and use a partial limitation: in Developer Settings, leave it on to Limit background processes, but select Without restrictions only for critical applications (setting in Settings → Apps → Permissions → Auto Run).

Method 5: Reset network settings to factory

If none of these methods work, it leaves you with a complete reset, which will remove all stored Wi-Fi networks, passwords, and APN settings, but often solves speed limit problems caused by configuration conflicts.

How to reset:

1. Open Settings → System → Resetting settings.
2. Select Reset Wi-Fi, Mobile Network and Bluetooth settings.
3. Confirm the action (you may need to enter a pattern lock or PIN-code).
4. After the reboot, set up a Wi-Fi and mobile network connection again.

If the problem was a software failure, the speed should recover. If not, it could be a hardware fault (e.g., a damaged Wi-Fi module or a 4G antenna).

💡

Before resetting your network settings, be sure to save your Wi-Fi passwords. Use applications like WiFi Password Viewer (root rights required) or manually take a photo. QR-router codes.

Additional Tips for Maximum Speed

Even after the restrictions are lifted, the speed may be lower than expected.

• 📡 Update the firmware of the communication module: Go to Settings → The phone. → Update the system and check for updates for Baseband (communication module). on some models (Xiaomi) 12S Ultra, it increases speed 5G 20 to 40%.
• 🔌 Use the original. SIM-Card: Cheap cropped nano-SIMs or cards from obscure operators often do not support modern communication standards (e.g., VoLTE or other low-cost mobile phone systems). CA — carrier-aggregation).
• 🛡️ Turn it off. VPN And antivirus: Apps like Kaspersky, Avast, or 1.1.1.1 can artificially restrict traffic.
• 🔄 Enable carrier aggregation (CA): In the engineering menu (#4636##) find the item LTE CA Configuration and activate all available combinations (e.g, B3+B7+B20 for Russia).

If you are using a dual-band Wi-Fi router (2.4 GHz + 5 GHz), force your phone to connect to a 5 GHz network.

1. Open the Settings. → Wi-Fi.
2. Tap on your network name and select Change Network.
3. Enable the option Additional settings and set the frequency range: 5 GHz.
