How to accurately measure the speed of the Internet on Xiaomi: from MIUI 12 to HyperOS

Have you noticed that pages load slower than usual, and YouTube videos are constantly “hung” on buffering? Or want to make sure that the provider provides the stated 100 Mbps? On Xiaomi smartphones, you can check the real speed of the Internet in several ways, from built-in MIUI tools to professional applications. But there are nuances: test results often depend on firmware versions, router model and even time of day.

In this article, you'll find 5 proven methods of measuring speed on Redmi, POCO and Xiaomi, from basic to advanced, explaining why the performance may differ from the ISP promised. And then how to interpret the results correctly: what ping is, why loading and recoil are never symmetrical, and when to sound the alarm. Let's start with the simplest, the built-in speed test in MIUI.

1. Built-in speed test in MIUI/HyperOS

Since MIUI 12 and later (including HyperOS), Xiaomi has developed its own Internet speed checker, which requires no additional applications and is integrated into the Wi-Fi menu. However, this method has limitations: it only works for wireless networks and does not show detailed data like jitter or packet losses.

To run the test:

1. Open the Settings. → Wi-Fi.
2. Tap on the name of your network (not on the switch!).
3. In the window that opens, click the Speed Test (or Check Network Speed in English).
4. Wait for the check to be completed (usually 10-20 seconds).

The results will be displayed as three key metrics:

• 📥 Download speed – how fast your phone receives data from the network (measured in Mbps).
• 📤 Upload speed – how fast a device sends data (usually 2-5 times lower than the download).
• 🏓 Ping – server response time in milliseconds (the lower the better for online gaming).

⚠️ Attention: Built-in test MIUI If ping is above 100ms, try alternative methods - the problem may be routing, not your Internet.

💡

If the download speed is below 10 Mbps after the test and the router is in another room, try bringing the phone closer to it or switching to the 5 GHz band (if supported).

2.Apps for precision measurement: Speedtest vs Fast.com

The built-in MIUI test is convenient, but not always accurate. Use specialized applications for more reliable results. The two most popular options, Speedtest by Ookla and Fast.com (from Netflix), work differently and give different data. Why is this happening?

Speedtest tests speed by uploading and retrieving files to nearby servers, while Fast.com only measures download speed by simulating streaming video. The latter option is useful if you want to check why Netflix or YouTube are slowing down, but it won't show ping or recoil speed.

Which server to choose in Speedtest? By default, the application selects the nearest one, but sometimes this is not optimal. For example, if you are in Moscow and the nearest server is in St. Petersburg, ping will be higher than the real one. Manually select the server of your provider (for example, Beeline, MTS or Rostelecom) for more accurate results.

3. Speed check through the engineering menu (for advanced)

If you want the most accurate data without the influence of third-party applications, you can use Xiaomi’s hidden engineering menu, which works on most models (except some POCO with custom firmware) and shows “raw” connection data, including signal level (RSSI) and connection type (Wi-Fi 5/Wi-Fi 6).

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636##
3. In the menu that opens, select Wi-Fi (Wi-Fi information) information.
4. Scroll down to the Wi-Fi Signal block – here the current connection speed in Mbps is displayed (updated in real time).

Note that Link Speed is the fastest speed possible between your phone and your router, and if it is significantly higher than the Speedtest test shows, the problem may be the provider or the network load.

⚠️ Warning: Not all options in the engineering menu are safe to change! avoid Testing and Usage Statistics tabs - incorrect settings can cause Wi-Fi module to malfunction.

Testing of mobile Internet speed (4G/5G)

Checking mobile internet speeds on Xiaomi has its own peculiarities, for example, on smartphones with 5G support (such as Xiaomi 13 Pro or POCO F5), the speed can vary greatly depending on:

• 📶 Signal level (with 1-2 "rods" the speed drops by 3-5 times).
• 🏙️ Network density (in the city center, speed is higher than on the outskirts).
• 🕒 Time of day (in the evening the network is overloaded, the speed is lower).
• 📱 Supported frequencies (not all operators in Russia use full spectrum) 5G).

To test the mobile internet:

1. Turn off Wi-Fi in the notification panel.
2. Run the Speedtest or nPerf.
3. Select your operator’s server (for example, for MegaFon, look for a server called Megafon).
4. Compare the results with the declared tariff values (for example, the tariff "All for 500" from Tele2 promises up to 100 Mbit / s, but actually gives 30-50 Mbit / s).

On smartphones with a Snapdragon 8 Gen 2 processor (for example, Xiaomi 14), 5G speeds can reach 3-4 Gbps, but only under ideal conditions: near the operator’s tower and in the absence of interference. In reality, even in Moscow, the average 5G speed ranges from 200-500 Mbps.

Disable Wi-Fi and VPN

Close background applications (especially torrents)

Select the operator server in Speedtest

Repeat the test 2-3 times in different places

5.Why is the speed on Xiaomi lower than on other devices?

You ran a test on Xiaomi and iPhone, and the results are 2 times different? It's not always the fault of the phone.

1. MIUI/HyperOS firmware limitations: Some regional versions of MIUI have artificially limited Wi-Fi speeds to save power. For example, on the Redmi 9A, the top speed of Wi-Fi is limited to 150 Mbps, even if the router supports 300 Mbps.
2. Hardware Limits: Cheap models (such as the POCO C50) are equipped with Wi-Fi 4 (802.11n) modules that cannot physically exceed 150 Mbps. Check the characteristics of your model on the website mi.com.
3. Background Processes: MIUI aggressively caches data and can eat up to 30% of bandwidth for updates or cloud services.

How do you check if the speed is software-limited? Install the WiFi Analyzer app and see how fast your network is running. If your phone is connected to 2.4 GHz and the router supports 5 GHz, switch manually:

1. Open the Settings. → Wi-Fi.
2. Tap on the network name. → Forget the net.
3. Connect again by selecting a network with 5G suffix in the list.

💡

If your Xiaomi doesn’t see a 5GHz network, check if your router supports this range.Older models (like the TP-Link TL-WR841N) only run at 2.4GHz.

6.How to improve the speed of the Internet on Xiaomi: 7 working ways

If the tests show that the speed is lower than expected, don't be quick to blame the provider. Often the problem lies in the settings of the phone or router. Here are proven optimization methods:

• 🔄 Change. DNS: By default. MIUI use DNS ISPs that might be slowing down. Go to Settings. → Connections → Private DNS and type dns.google (or 1.1.1.1 for Cloudflare).
• 📶 Enable the Maximum Performance mode: In Settings → Battery → Power modes select Performance – this will disable background data restrictions.
• 🛠️ Update your router firmware: Outdated router software can cut speeds. Go to the router's admin panel (usually at 192.168.1.1) and check for updates.
• 🔌 Use cable instead of Wi-Fi: If the router supports USB-terminal, connect the phone through OTG-Adapter – This eliminates interference from other devices.

For models with HyperOS (such as Xiaomi 14 or Redmi K70), add one more item:

• 🚀 Turn off Adaptive Communication: Go to Settings → SIM-maps and mobile networks → Adaptive communication and deactivate the option. It automatically switches. 4G/5G, Sometimes you choose a lower speed standard.

⚠️ Note: If after all the manipulations, the Wi-Fi speed does not exceed 50 Mbps, and the router gives 300+ Mbps on other devices, the problem may be the antenna of the phone. On Redmi Note 10 and older, it is a common "disease" - you need to replace the Wi-Fi module at the service center.
