Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the manufacturer’s stated connection speed is not true. The interface of MIUI or HyperOS can be overwhelmed by background processes that stealthily consume traffic and reduce network response, this is especially noticeable when watching high-resolution video or during online games, where every millisecond of ping matters.
The problem is often not the weakness of the communication module, but the software settings that are optimized by default to save charge, not maximize performance. Aggressive energy savings can limit the operation of network adapters, creating artificial bottlenecks. In this article, we will discuss proven methods that will help you to get the most out of your device without obtaining superuser rights.
Many users do not even realize that the standard settings DNS-ISP servers can be slow or congested, and replacing them with faster alternatives from Google or Cloudflare can do wonders with page response rates.
Shift. DNS-servers to speed up response
One of the most effective ways to increase the speed of loading web pages is to switch to public ones. DNS-Standard settings that automatically receive a smartphone from an operator or router often work slowly due to remoteness of the servers or their poor optimization. MIUI There is a built-in function "Private" DNS», This allows you to change these parameters without obtaining root rights.
To activate this feature, go to the Settings menu → Connection and Sharing → Private DNS. The default mode is Auto, but for maximum speed, you should choose the DNS Provider Host Name and manually specify the address. It is recommended to use the servers dns.google or 1dot1dot1dot1.cloudflare-dns.com, which are famous for their speed and stability around the world.
💡
After changing the DNS, restart your smartphone so that the changes will take effect for all apps, including those already running in the background.
This is especially effective if pages can’t load for a long time, but then the content is downloaded quickly, which is a classic sign of problems with the resolution of domain names. After applying the settings, you will notice that the sites begin to “drawn” instantly.
💡
Using a private DNS bypasses the provider’s slow servers, significantly reducing response time when navigating websites.
Resetting Access Point Settings (APN)
If problems are observed exclusively when using mobile Internet (3G/4G/5G), then the reason may lie in the incorrect settings of the APN access point. Over time, these profiles can accumulate errors or old parameters that conflict with the current standards of operator communication.
To perform the reset, open Settings → SIM-Maps and mobile networks. Select your SIM card, then go to Access Points (APN)». In the upper right corner of the screen, click on the three-dot menu and select Reset. The system will automatically delete current profiles and create new ones that are optimal for your carrier.
⚠️ Note: Do not manually remove access points unless you are sure of their purpose, as this can lead to a complete lack of mobile internet before manually reconfiguring.
After reset, it is recommended to turn on and off the flight mode so that the communication module is re-registered in the network with updated parameters, this action forcibly reconnects the device to the nearest cell tower, choosing the best data channel.
☑️ Checklist for setting APN
Disabling traffic optimization and limits
Xiaomi’s shell comes with powerful traffic control tools that can by default limit the speed of background apps.The Traffic Limit feature is designed to save users money, but it often works too aggressively by blocking the necessary network requests of the system or messengers.
To disable restrictions, go to the Security → Traffic → Settings (cog icon) application to check if there are speed limits for individual applications, and go to the Network Speed section to make sure that important programs (browser, navigator, games) do not have a 1KB/s limit or a complete lock.
- 🚀 Open the Security app and select Traffic section».
- 🚀 Go to the settings and find the item “Restriction of traffic».
- 🚀 Check the list of applications and remove restrictions from those who need fast Internet.
- 🚀 Make sure the Traffic Savings feature in the notification curtain is turned off.
Also, in the Settings menu → Connection & Sharing → Traffic savings, it’s worth checking the global settings. If this mode is active, the system will prevent background synchronization of photos, mail and updates, which can create a sense of slow network performance as a whole.
Wi-Fi settings: frequencies and ranges
In apartment buildings, the 2.4GHz band is often overloaded with signals from neighbouring routers and household appliances, such as microwaves. Redmi smartphones support 5GHz bandwidth, which provides significantly higher data rates and lower latency, although it has a smaller range.
To force a switch to a faster network, go to Settings → Wi-Fi → Select your network. In the network settings menu, find “Wi-Fi Frequency Range” and select “Prefer to 5GHz.” If your router broadcasts one network with both bands, try splitting them in the router’s settings or use the Smart Wi-Fi feature with caution, as it doesn’t always switch ranges correctly.
| Parameter | Range 2.4 GHz | 5 GHz range |
|---|---|---|
| Maximum speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Range of action | High (up to 50 m) | Medium (up to 20 m) |
| Wall penetration | Good. | Bad. |
| Level of interference | High-pitched | Low. |
It is also worth paying attention to the parameter. MAC-address in the Wi-Fi settings. By default, new versions of Android use randomized MAC-address for privacy, but some older routers may not work properly with this feature, resetting speed «MAC-Device address in extended settings of your Wi-Fi network.
What if the router does not support 5 GHz?
Resetting network settings as a radical method
If the network configuration errors become critical and simple methods do not help, you need to perform a complete network reset, which will return all the parameters of Wi-Fi, Bluetooth and mobile Internet to factory state, removing saved passwords and associated devices, but will not affect your personal files or applications.
Resets can be done via Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn of the consequences, then you will need to confirm the action with a password unlock the screen. Once you reboot the phone will be “clean” in terms of network protocols.
⚠️ Before reset, be sure to write down passwords from important Wi-Fi networks, as after the procedure they will have to be re-entered manually.
This method often helps to resolve driver conflicts that may have arisen after updating the HyperOS firmware or installing specific applications for tweaking the system. If the speed has not recovered after that, the problem is likely to lie on the hardware or provider side.
💡
A complete network reset eliminates software configuration conflicts, but requires re-authorization across all wireless networks.
Hardware factors and location selection
And you can also think about the physical limitations: a thick case with metal elements or a magnetic cover can shield the antennas of a smartphone, reducing the signal level by 30-50%. Take off the case and check the signal level - if it grew, the reason for the slow Internet was precisely the accessory.
In addition, overheating of the processor or modem leads to trottling, in which the system artificially lowers the frequency of operation, which negatively affects the speed of processing network packets. If the phone is hot to the touch, let it cool down and check the speed again. It is also worth checking whether the storage is fully loaded, since when the memory is filled by more than 90%, the system runs slower, including network operations.
- 📶 Remove the protective case if it contains metal inserts.
- 📶 Check your phone for overheating before speed test.
- 📶 Free up space in your internal memory if you have more than 90 full%.
- 📶 Make sure that no metal stickers are pasted on the antenna areas.
In some cases, it helps to use an engineering menu to select a preferred type of network ##4636## in dialer, you can go to the test menu. Select "Phone Information" and in "Set up your preferred network type" select LTE Only or LTE/TD-SCDMA/WCDMA. This will prevent the phone from switching to slow. 2G/3G squabbling.
