How to speed up the Internet on Xiaomi Poco X3: a complete guide

Poco X3 smartphones are well-deservedly considered favorites due to their excellent price-performance ratio. However, even the powerful Snapdragon processor will not be able to provide comfortable surfing or stable video communication if the communication modules are not working correctly. Low page loading speeds, constant video buffering on YouTube, and high ping in online games can be caused by software failures or incorrect settings of the MIUI system.

Before you blame a carrier or provider, it’s worth doing a comprehensive diagnostic of the device. Often the problem lies in the accumulated cache of network services, outdated APN configurations, or Bluetooth devices conflict with the Wi-Fi module. In this article, we will discuss effective methods that will help you to get the most out of your Poco X3.

We won’t use the dubious accelerator apps from the Play Store, as they often only consume battery life. All of the solutions we’ve proposed are based on built-in Android features and deep system customization. Be prepared for the fact that some steps will require care, but the result is worth it.

Diagnostics of current connection and elimination of interference

The first step is always to make an objective assessment of the situation, not to rely on the subjective feeling of “slow”, but rather to use accurate tools, run a built-in speed test or use popular services like Speedtest by Ookla to measure current ping and bandwidth.

Often, slow speeds are caused by physical obstacles or electronic interference. Microwave ovens operating at 2.4 GHz can completely jam the Wi-Fi signal in the kitchen. Similarly, dense concrete walls or metal foil in the insulation of the house can reduce the signal to a minimum.

⚠️ Warning: If you use a metal case or magnetic cover, remove it during testing.The metal shields antennas located at the ends of the Poco body X3, Critically reduces the quality of signal reception.

It's also worth checking if the range is congested. In apartment buildings, neighborhood routers create a porridge of signals, especially on the 2.4 GHz channel. Switching to a freer channel or switching to 5 GHz can make a difference.

• 📶 Reboot the router, disconnect it from power on 10-15 Seconds to Reset Memory Errors.
• 📶 Check if the phone is enabled with Traffic Saving mode, which limits background activity.
• 📶 Make sure the date and time are set automatically, as the out-of-synchronization disrupts the job. SSL-certificate.

Basic settings of the access point and resetting networks

The most effective way to eliminate software errors in the operation of communication modules is to completely reset the network settings, which will return all parameters of Wi-Fi, Bluetooth and mobile networks to factory values, removing accumulated configuration errors.

To perform this operation on Poco X3, you need to go to the settings menu. The path usually looks like this: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you that saved passwords will be deleted.

Once reset, the phone will reboot. You'll need to re-enter the password from your home Wi-Fi network. It's a small inconvenience that often solves problems with persistent connection breaks or inability to get a hold of it. IP-address.

It is important to note that network resets do not affect your personal files, photos or contacts, but setting up specific applications that depend on the local network (such as a smart home) may require re-authorization.

Optimizing DNS and APN settings for mobile internet

If the problem is relevant for mobile Internet, you should pay attention to the access point settings (APN). Operators often provide standard settings that may not be optimal for your region or the current load on the tower.

Shift. DNS-A server to a faster and more reliable one, such as from Google or Cloudflare, can significantly speed up server response and the opening of “heavy” sites. DNS.

To change your APN settings, go to Settings → SIM cards and mobile networks → (Select SIM card) → Access Points (APN). Create a new point by copying the existing settings, but changing the DNS 1 and DNS 2 fields to the values from the table above.

Remember to save the new access point and activate it by ticking the box, and then it is advisable to turn on the flight mode for 10 seconds and turn it off so that the network reconnects with the new parameters.

Hidden developer settings and engineering menu

There is a hidden section for developers on Android that allows you to fine-tune the behavior of the radio module. To get there, you need to quickly click on the MIUI version number 7 times in the About Phone section.

In the developer menu, we're interested in "Wi-Fi Aggregation" or "Wi-Fi Acceleration." However, more advanced users should pay attention to modem modes. Sometimes switching a preferred network type helps to lock the signal.

There's also an engineering menu available through the ##4636## code in the phone app, and you can find the Phone Information section here and force a network type, like LTE Only, to be displayed, which is useful in unstable reception areas where the phone is constantly jumping between 3G and 4G.

⚠️ Attention: Compulsory regime LTE Only can cause incoming voice calls to stop coming in if your carrier doesn't support VoLTE technology.Be careful when using this feature.

Also, the developer settings can find the option “Always turn on mobile Wi-Fi”, which can help if the phone tries to constantly scan the network in the background, consuming resources and causing interference to the main connection.

• 🚀 Turn off Traffic Monitoring in Wi-Fi settings to reduce the background load on the module.
• 🚀 In the section “On the telephone» → «All specs" can be seen at the actual connection speed in the instant.
• 🚀 Use of the protocol IPv6 customized APN Sometimes gives an increase in speed of modern operators.

The impact of Bluetooth and background processes on speed

Many Poco X3 users are unaware that Wi-Fi and Bluetooth modules operate in adjacent frequency bands (2.4 GHz).Simultaneously active data transfer over Wi-Fi and the operation of a Bluetooth headset or watch can cause serious interference.

If you listen to music through wireless headphones and simultaneously download a file over Wi-Fi, the speed can drop significantly, in this case, switching the router to a frequency of 5 GHz, which does not intersect with Bluetooth, will help.

Also, it's worth checking background processes. Apps like Telegram, Instagram, or cloud storage can sync data all the time, open Task Manager and see if there's traffic loading in the background.

💡

Tip: To temporarily speed up the loading of a large file, turn on Do Not Disturb mode and close all unnecessary applications, which will free up the CPU and radio module for one task.

Cleaning up the cache of Google Play services and the app store itself can also help, and sometimes bloated cache causes conflicts when checking licenses or downloading content, creating the illusion of slow internet.

Analysis of frequency ranges and choice of router

The Poco X3 supports modern Wi-Fi standards, but it is limited by the capabilities of your router. If the router is old and only works in the 2.4 GHz range, then speeds above 40-50 Mbps will be extremely difficult to achieve, even with a perfect signal.

The 5GHz range provides much higher speeds and is less prone to interference from neighbors, but has a shorter range and passes through walls worse. 4K-Video is the only right choice.

Check your router's specifications. If it supports Wi-Fi 5 (ac) or Wi-Fi 6 (ax), make sure your phone's settings select automatic switching or 5GHz network priority.

It also makes sense to check the channel width in the router settings. 20 MHz is optimal for 2.4 GHz (for stability), and 80 MHz or even 160 MHz for maximum speed for 5 GHz, if the environment allows.

💡

The top speed on the Poco X3 can only be obtained paired with a dual-band router (5 GHz) and using DNS from Google or Cloudflare.
