Owners of the popular Poco X3 Pro smartphone often face a situation where the declared speed of a mobile or Wi-Fi connection does not correspond to real indicators, this can be due to the peculiarities of the MIUI or HyperOS shell, as well as to incorrect network settings. In this article, we will discuss proven methods that will help significantly improve the stability and speed of data transfer.
First, eliminate the trivial but often overlooked factors, check whether the power saving mode is activated, which may limit the background activity of the network modules, and make sure you are in a zone of confident reception, especially if you use mobile Internet. 4G/LTE. Software failures in the operation of the communication module are often solved by simply restarting the device or switching flight mode.
We'll move on to a deeper setup, and many users don't know that ISP standard DNS settings are often overloaded, and replacing them with faster alternatives is one of the most effective ways to speed up page response. Using Google's or Cloudflare's DNS can reduce ping in games and speed up site openings by 15-20%. Be careful when you enter data so you don't disrupt your connection.
Special attention should be paid to the settings of the APN hotspot. It is through this profile that your phone communicates with the carrier tower. If it has outdated protocols or the wrong type of APN, the speed can drop even with a perfect signal. We will consider how to properly create a new profile for your carrier.
Basic optimization of network settings and reset
The first step is to set the basics correctly. Often the system automatically selects the not-fast communication standard, preferring speed stability. You need to manually check your preferred network type. → SIM-Maps and mobile networks and select your active SIM card.
In the "Preferred Network Type" section, make sure you select a value Preferably 5G or Preferably LTE. If the phone is "stuck" on 3G or H+, the speed will be low. It's also worth checking if the "Traffic Savings" feature is enabled, which can block the background synchronization of applications, creating the illusion of slow internet.
If simple switching didn't work, reset the network settings, and this action will return all network settings to factory values by removing the accumulated configuration errors. Importantly, after that, you will need to re-enter the Wi-Fi passwords, but the contacts and photos will remain in place.
- 📱 Go to Settings. → Connection and sharing.
- 🔄 Select Reset Wi-Fi, Mobile Networks and Bluetooth.
- ⚙️ Click Reset button at the bottom of the screen and confirm the action.
- 📶 Wait for the reboot of communication modules and check the speed.
☑️ Diagnosis before reset
⚠️ Note: Resetting your network settings will delete all stored Wi-Fi passwords and Bluetooth pairs. Make sure you remember the home network access keys, or write them down in advance.
Changing DNS servers to speed up response
One of the most effective methods is the change. DNS-Standard addresses that your Poco automatically receives X3 Pro from the operator, often running slowly or not coping with a large number of requests. DNS Large tech companies can speed up domain name resolution.
To perform this procedure on Android 9 and above (and on Poco) X3 Pro is more recent, no root rights are required. Just use the built-in "Private" function. DNS». This provides encryption. DNS-requests and often increases the speed of opening pages.
Enter the address of a trusted server in the appropriate field. The most stable and fast servers at the moment are considered to be the servers of Google and Cloudflare. They have a huge infrastructure and servers around the world, which ensures a quick response regardless of your location.
dns.googleAlternatively, Cloudflare offers:
1dot1dot1dot1.cloudflare-dns.comOnce you enter the address, click Save. If the Internet stops working, it means that the entered address is unavailable or has a typo, in which case, return the setting to the position "Auto", You can also use special applications to change the DNS, but the built-in method is more reliable and does not consume battery.
What to do if DNS is not used?
Setting up an APN access point for mobile data
The APN is the gateway between your SIM card and the carrier’s Internet. Sometimes the providers change the technical parameters and the phone leaves old records, which leads to unstable work. Creating a new APN profile with optimal parameters often solves the problem of “slow” 4G.
Go to the Settings menu → SIM-maps and mobile networks, select a SIM card and go to “Access Points (APN)». Click the “New Access Point” button or icon «+». It is important to fill in the fields “Name” and “Type” correctly. APN». The remaining fields can be left blank or copied from an existing profile if it works normally.
The APN type field must specify default,supl. This is the standard protocol for data transmission and GPS auxiliary services. IPv4/IPv6 is better set to IPv4/IPv6 so that the phone can use any addresses provided by the operator.
| Parameter | Value for adjustment | Description |
|---|---|---|
| Name. | Fast Internet | Arbitrary profile name |
| APN | internet | Depends on the operator (often Internet or mts) |
| Type APN | default,supl | Mandatory parameter for data operation |
| Protocol | IPv4/IPv6 | It is compatible with all networks |
After filling in all the fields, be sure to click the three dots in the menu corner and select Save. Then activate the profile you created by ticking next to it. Reboot your phone to apply the changes. If the speed hasn't increased, try removing old, unused APN profiles, leaving only the new one.
💡
For different operators, the value of the APN field may vary, for example, for Mefon - Internet, for Beeline - Internet.beeline.ru. Check the current data on your operator's website.
Use of engineering menu and hidden functions
Hidden in the MIUI shell is a powerful engineering menu that allows you to control the radio module at a deep level, and it can force you to switch your phone to work only at certain frequencies, which is useful in places where the network is congested.
To enter the test menu, enter the code ##4636## in the “ringer” if the code did not work (the operator could block the code). USSD-You can use the Activity Launcher app from Google Play by looking for the Testing activity.
Inside the menu, find Set Preferred Network Type. By default, it can be a value that allows all standards. You can try to choose an option that contains LTE Only. This will cause the phone to ignore 2G and 3G towers, always holding on to 4G.
⚠️ Attention: Regime «LTE Only" can cause incoming calls to stop going if your carrier does not support VoLTE technology.Use this mode with caution and only when you only need the Internet.
Also, you can see the actual strength of the signal in dBm. A value closer to 0 (for example, -80 dBm) is better than a value farther from zero (for example, -110 dBm). If the signal is very weak, software tricks will not help - you need to physically move closer to the window or tower.
💡
The engineering menu is a powerful tool, but changing the settings of the radio module without understanding the consequences can temporarily deprive you of communication.
Cache cleaning and system optimization
The accumulated garbage in the system and the cache of network services can slow down the Internet. In Android, the Download Manager process and the system cache are responsible for this, cleaning them up is safe and often helps if the Internet hangs when pages load.
Go to Settings → Apps → All apps. Find Download Manager and Google Play Services in the list. Select Memory for each and click Clear Cache. Don’t confuse it with Clear Everything so you don’t delete important data.
Also, check whether the system limits the background activity of applications that need constant Internet (messengers, mail).In the Battery and Performance menu, make sure that there is no strict restriction for important applications. MIUI is known for its aggressive energy savings, which can "kill" network connections in the background.
It's also recommended that you disable Adaptive Connection if it's active, which tries to switch between Wi-Fi and mobile internet to save traffic, but in practice often creates delays and breaks in connection, and you can find it in advanced Wi-Fi settings.
- 🧹 Clear the cache of the Downloads and Google Play Services apps».
- 🔋 Check the power saving settings for network applications.
- 🚫 Turn off Adaptive Connection in Wi-Fi settings.
- 📲 Remove unused apps that consume traffic in the background.
Impact of updates and third-party software
Often Internet problems on the Poco X3 Pro occur after a firmware update. New versions of MIUI may contain bugs that affect modem drivers. If the problem occurs immediately after the update, wait for the patch or, in extreme cases, consider rolling back on the previous version.
There's a myth that third-party Internet accelerator apps actually increase speed, and in fact, most of them just change the DNS (which we've done manually) or just show ads, and the only thing they can do is block ads in the apps, which will visually speed up page loading.
However, installing modified versions of the system or obtaining root rights can give access to the system files hosts, where you can block advertising domains at the system level, but for the average user this is risky and can lead to loss of warranty and unstable banking applications.
