How to remove the Internet speed limit on your Xiaomi phone

The problem of low mobile Internet speeds on Xiaomi smartphones often comes up suddenly, causing users to blame the carrier or outdated equipment. However, in most cases, the reason is the software limitations of the MIUI or HyperOS shell, which aggressively save traffic and background activity of applications. Understanding how the traffic prioritization system in Android works allows you to effectively bypass these locks without obtaining root rights.

Before we go to radical methods, we need to rule out trivial factors such as cell tower overload or physical antenna damage. Often users forget that the power saving mode on can artificially "suffocate" loading speed in the background processes. We will look at proven ways to restore maximum channel bandwidth.

In this article, we will take a closer look at access point settings, hidden menu options, and system constraints implemented by the manufacturer. Xiaomi is famous for its customization, but sometimes these features interfere with the normal operation of the network. Follow the instructions consistently to find and eliminate a bottleneck in your system.

Diagnostics and basic network settings

The first step should always be to make a thorough diagnosis of the current state of the connection, and you should not immediately get into complex settings if the problem lies in the banal switching between standards. 3G and 4G. Go to the settings. SIM-maps and make sure that the "Network Type" option is selected LTE or 5G, If your service and service provider support this.

Often, the speed drops due to accumulated network cache or modem failure. Simple device reboot does not always help, so it is recommended to reset the network settings. This action will return all connection parameters to factory values, removing possible conflicting configurations, but will save your personal data and applications.

Pay attention to the indicators in the status bar. If you see an "H" icon.+» instead «4G» or «LTE», So the phone can't get fixed at high speed frequencies, and in those cases, it helps to temporarily switch on the flight mode. 10-15 Seconds, which causes the modem to re-register on the network and choose the optimal base station.

• 📶 Check if the Traffic Saving mode is activated in the notification curtain.
• 🔄 Reset network settings through the Connections and Sharing menu».
• 📱 Make sure the case does not cover the antenna modules of the smartphone.
• ⚙️ Check for system software updates, as they often contain patches for the modem.

⚠️ Note: Resetting your network settings will remove saved passwords from Wi-Fi and a pair of Bluetooth devices. Write down important data in advance or be prepared to re-enter it.

Manually configuring the APN access point

One of the most effective methods of speeding up the Internet is manual adjustment of access point parameters (APN). telecom operators often provide standard settings that do not take into account the specifics of the operation of modern Xiaomi smartphones. Creating a new access point with optimized parameters allows you to bypass some of the limitations of the provider.

To enter the settings menu, go on the Settings path → SIM-maps and mobile networks → Choose yours. SIM → Access points (APN). Here you need to create a new point by copying the data from the active one, but changing the key fields. APN» and “Roaming protocol” APN».

💡

When creating a new access point, be sure to click the Save button in the menu (usually three dots or the button at the bottom), otherwise the changes won't apply.

In the APN type field, it is recommended to prescribe default,supl,dun. The Dun option often helps unlock the full speed for the distribution of the Internet, which operators sometimes cut. Also change the MTU if your operator maintains non-standard packet sizes, although standard values are sufficient for most users.

Once you save a new access point, make sure to select it by setting a marker, and reboot your phone. If the Internet is gone, return the settings to Default. Experiment with the username and password fields only if the specific carrier requires it, otherwise leave them empty.

Disabling traffic savings and background restrictions

The MIUI shell and the new HyperOS have an aggressive energy-saving policy that often stifles the background activity of apps, including Google Play system services.This can create the illusion of slow internet when pages load in jerks.

Go to Settings → Apps → All apps. Find Google Play Services and Google Chrome (or your browser) in the list. Go to Saving Charge and select No Limits option, which will allow the system to keep the network connections of these apps connected even when the screen is locked.

There is also a hidden system service called com.android.providers.downloads, which is responsible for downloads. If it's limited, files can download at extremely low speeds or stop altogether. Apply the same "No Limits" settings for this component of the system.

Don't forget the global Traffic Savings switch in the curtain. If it's activated, the system will compress traffic and block application updates in the background. For maximum speed, this mode should be turned off, especially if you're in a confident reception zone.

⚠️ Warning: Turning off battery saving for all applications at once can result in faster battery discharge throughout the day.

Using an engineering menu to select frequencies

For advanced users who want to make the most of their device, there is an engineering menu available, where you can force the phone to only run in the LTE band, ignoring the slower but long-range 2G and 3G. This is especially true in places where the signal is unstable and the phone is constantly "jumping" between standards.

To get to the menu, open the Phone app and dial the code ##4636##. If the code is not working (it is blocked on some versions of MIUI), you can use the Activity Launcher app from the Play Market by finding the activity of Testing → Phone information.

Select the value LTE After that, the phone may lose voice communication if the operator does not support VoLTE technology, as standard calls go through the phone. 2G/3G. In this case, you will have to return to the choice. LTE/TD-SCDMA/GSM or similar combination.

Using LTE Only significantly improves the speed of data exchange in low-reception areas, as the phone stops wasting time scanning other frequencies. However, if you leave 4G coverage, the Internet will completely disappear until you return to automatic mode.

Resetting network settings and cleaning the cache

If the software settings didn't work, there may have been a build-up of configuration errors in the system, and resetting network settings is a secure operation that doesn't affect personal files, photos or contacts, and only deletes the connection settings: Wi-Fi, Bluetooth, and mobile.

Resets can be done via Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Once confirmed, the phone will restart. This often helps if the Internet is unstable after a firmware update.

Additionally, clear the cache of system applications responsible for the network. Go to Settings → Apps → Show everything → Installer Package Manager (or similar system services) and click “Clear Cache.” Don’t confuse it with “Clean Data”, which can lead to crashes.

• 🗑️ Resetting network settings eliminates conflicts IP-address.
• 📲 Cleaning up the browser cache can speed up the loading of web pages.
• 🔄 Rebooting in safe mode will help identify the culprit of the brakes.
• 🛠️ Reset to factory settings - an extreme measure for software errors.

The Impact of DNS and Third-Party Applications

Often, the speed limit is not due to the communication channel, but to the slow response of domain name servers (DNS). Your operator's standard DNS can be overloaded. Using fast and secure DNS, for example, from Google or Cloudflare, can significantly speed up the opening of sites.

On Android 9 and above, you can change the DNS settings: Settings → Connection and Sharing → Private DNS. Select “Host Name Provider” and type in dns.google or 1.1.1.1. This change applies to the entire device and works for both Wi-Fi and mobile internet.

💡

Shift. DNS-A server to a faster one (e.g., 1.1.1.1) often solves the problem of long page loads even at normal connection speeds.

Also check the installed applications. Some "accelerators" or antiviruses can pass all traffic through their servers for verification, which creates an additional delay. VPN-Services to assess their impact on speed.

⚠️ Attention: Use of free of charge VPN-services of unknown developers can lead to leakage of personal data and further reduction of speed due to encryption of traffic.
