Xiaomi’s modern smartphones are famous for their functionality and affordable price, but communication quality and data speed remain critical for any user. When you notice that YouTube videos are delayed and pages in the browser open slowly, the first thing you want to do is check the connection quality. On devices running MIUI shells or HyperOS, there are many ways to diagnose the problem, from embedded utilities to third-party applications.
To make a precise diagnosis, you need to understand the difference between the theoretical capabilities of your tariff and the real speed that your smartphone receives. Often the reason lies not in the provider, but in the settings of the device itself, congestion of Wi-Fi range, or even in the physical location of the router. In this article, we will discuss all the available verification methods in detail so that you can objectively assess the quality of communication and improve the performance if necessary.
To get the most accurate data, close to real-world usage, the best use of specialized applications. The leader in this field for many years is Ookla Speedtest, which has a huge database of servers around the world. This allows you to choose a measuring point that is as close to your location as possible, which eliminates the impact of distance on the result. Another great option is the application Fast.com, developed by Netflix. Its main advantage is minimalism and no advertising, as well as speed checking for streaming content. If you often watch movies or broadcast videos, this test will be the most relevant for your use. Also worth mentioning is SpeedCheck, which provides a detailed analysis of latency (ping) and jitter, which is critical for online gaming. 📊 Built-in tester Xiaomi Speedtest Application Through the site in the browser Never check the Installation of third-party applications gives a number of advantages over browser versions of tests. Mobile applications have lower process priority in the system, which allows them to more accurately measure channel bandwidth, bypassing browser restrictions, and they also store the history of measurements, allowing you to track the dynamics of communication quality from your operator at different times of the day.
Step-by-step: how to conduct an accurate test To the results of the measurement were reliable and they can be used as an argument when contacting the technical support provider, you must properly prepare for testing. Simply pressing the Start button without prior preparation can give you distorted data due to background processes or a weak signal: 📶 Turn off all background downloads: Close torrents, stop updates in Google Play and pause syncing photos. 📵 If you are testing Wi-Fi, get closer to the router, but not close (optimal). 2-3 (f) to eliminate the effect of signal attenuation. 🔄 Switch your smartphone to Flight mode 10 seconds, then turn it off to reset the current connection to the tower or access point. 📱 Make sure your smartphone screen is on and doesn’t go into power saving mode during the test. ☑️ Checklist before testClose background applicationsDisable VPNGo to routerReset network Run test Completed: 0 / 5 After preparation, launch the selected application and wait for the process to be completed. Pay attention to three main parameters: Download (load speed), Upload (recoil speed) and Ping (latency). 4G/LTE Ping is considered normal in networks. 50-60 MS, and for Wi-Fi, up to 10-20 If the values are significantly higher, this indicates a communication channel problem or network congestion.
Analysis of results: speed standards for 4G And when you get the numbers on the screen, many people are confused as to whether they're good or bad, and the real speed is always lower than the rate, because of the overhead of data protocols and the loss of air. Understanding the physical limitations of technology will help you objectively evaluate how the network works. The table below shows the approximate speed values that can be considered the norm for different types of connection in a city: Connection type Download Speed Upload Ping) 4G (LTE) 10 – 50 Mbit/s 5 – 20 Mbit/s 30 – 60 ms. 2.4 GHz 20 – 60 Mbit/s 10 – 30 Mbit/s 10 – 30 ms. 5 GHz 100 – 400+ Mbit/s 50 – 200+ Mbit/s 2 – 10 miss 5G (NSA/SA) 100 – 800+ Mbit/s 50 – 100+ Mbit/s 10 – 30 Providers specify the speed "up to" a certain value in ideal conditions. In reality, the speed is cut due to the quality of the cable, the load of the base station, the power of the router and interference. 60-80% It's important to remember that the Wi-Fi frequency range is key. The 2.4 GHz band is heavily noisy with neighbouring routers and appliances, so the speed here rarely exceeds 50-60 Mbit / s, even at a powerful tariff. The transition to 5 GHz allows you to unlock the potential of high-speed connections, but the range of such a signal is much smaller.
If the tests show a speed that is significantly lower than expected, you need to do a series of actions to troubleshoot. Start with the simplest thing: reboot the router and smartphone. This simple action helps to reset errors in network stacks of devices and reconnect to a less congested communication channel. 💡Try manually selecting the type of network in the engineering menu. 4G/3G/2G (Auto) by “Only LTE» It helps to fix a stable connection in weak signal areas, preventing constant jumps between standards. If the problem persists only on one particular Xiaomi smartphone, try resetting the network settings. This action will return Wi-Fi, Bluetooth and mobile settings to factory values by removing all saved passwords and pairings. Path to reset: Settings → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth. 💡If the slow speed is observed on all devices in the house, the problem is on the ISP or router side. Unless on Xiaomi it is the settings of the phone or its antenna module.
