Slow internet on Xiaomi Poco can turn watching videos into slideshows and playing online games into a test of patience. The reasons range from smartphone misconfiguration to operator problems, but 80 percent of the time, users can speed up the connection without going to a service center. This article covers all the diagnostic and optimization methods, from basic checks to hidden features. MIUI, Even the official instructions are silent.
We will analyze not only standard tips like a phone reboot, but also technical nuances: how to forcefully switch to a new device. 4G+ instead 3G, Why is Poco? F3 It can be hung on a weak signal and how to get around operator speed limits, with a particular focus on solutions for gamers and streamers, where not only megabits are important, but also stable ping.
If your Poco suddenly starts to slow down on the network, don't be quick to blame the provider. Half of the time, the device settings are to blame. MIUI can artificially limit the speed of background applications, and the double mode SIM Sometimes it conflicts with network priority, and then you will learn how to identify and fix such problems in 5-10 minutes.
It is important to understand the difference between real speed (as the tests show) and perceived speed (how fast websites load). For example, if ping is above 150 ms, even 100 Mbps will seem โlagging.โ So in this article we touch on both technical performance and subjective acceleration.
1. How to measure Internet speed on Poco
Before you set up something, you need to know how fast you really are, and using the wrong services or testing in the wrong conditions can give you false results, like running a speed test through the wrong conditions. VPN or during the download of the system update, the indicators will be underestimated by 30-50%.
The best tools to test on Xiaomi Poco:
- ๐ Speedtest by Ookla is the most accurate for mobile networks, but requires a shutdown VPN Use your operator's servers (for example, for MTS, select "Moscow, MTS").
- ๐ nPerf, an alternative with advanced ping and jitter data (important for online gaming), shows real file download speeds, not just synthetic tests.
- ๐ฑ Built-in test in MIUI โ Hidden function. Press the mobile network icon in the notification panel. โ Select Measure Speed. Works without installing apps, but less accurate.
For objective results:
- Turn off Wi-Fi and leave only mobile internet.
- Close all applications through Recent (swipe up).
- Do 3 tests in a row and take the average.
โ ๏ธ Warning: If the speed is below 10 Mbps with full signal 4G, The problem is probably on the operator's side, but if the indicators "jump" (50 Mbps, 2 Mbps), the phone settings are to blame.
2. Basic network settings: what can be changed without root
Most Poco users do not even know that the MIUI Hidden options for manually configuring mobile Internet, which do not require superuser rights, but can significantly improve connection stability.
Open the Settings. โ SIM-maps and mobile networks โ [Yours. SIM] โ Network type. Options are available:
- ๐ถ 4G (recommended) โ automatic choice between 4G and 3G. Suitable for most cases, but can get stuck on a slow network.
- โก Only 4G โ Useful if the phone is switched to a regular 3G Minus: In areas of low coverage, communication can disappear completely.
- ๐ 3G/2G (Autos only to save charge. Speed will be lower, but the battery will last longer.
For Poco models F3/F4/F5 supportive 5G There will be an additional paragraph 5G/4G/3G/2G. However, in Russia 5G-Networks are still only in test mode (for example, in Moscow at MTS), so to include this mode makes sense only in large cities.
Another hidden parameter is the mode. LTE. To activate it:
- Enter the dialer code: ##4636##
- Select Phone Information โ Network type installation.
- Try the options. LTE only LTE/UMTS auto.
โ ๏ธ Attention: On Poco X3 If you have lost communication after the change, return the settings to the Auto and restart the phone.

3. APN-Settings: Why They Are Important and How to Reset Them
APN (Access Point Name is the address that connects the phone to the carrier's Internet, and if it's not configured correctly, the speed can drop by 10 times, and some sites won't open at all. MIUI shift SIM-map APN Sometimes it gets confused by standard values that are not optimized for your tariff.
To check and reset the APN:
- Go to Settings. โ SIM-maps and mobile networks โ [Yours. SIM] โ Access points (APN).
- Click on three dots in the upper right corner โ Reset to default values.
- If the reset doesnโt help, create a new one. APN manually (options can be found on your operator's website).
An example of the right APN for popular operators (2026):
| Operator. | APN name | APN | Type of authentication |
|---|---|---|---|
| MTS | mts | internet.mts.ru | PAP |
| Beeline | beeline internet | internet.beeline.ru | PAP |
| Megaphone | MEGAFON | internet | PAP |
| Tele2. | tele2 internet | internet.tele2.ru | PAP |
After the change APN You have to restart your phone. The new settings only apply after the communication module restarts.
What to do if the APN is not saved?
4.Dual problems SIM: Why does the second card steal speed?
Poco models F1/F2/F3 two-way SIM-maps, but few know that the simultaneous operation of two networks can reduce the speed of the 20โ40%. This is due to hardware limitations: one communication module cannot fully serve two networks at the same time.
How it manifests itself:
- ๐ Speed on the main SIM falls when the second SIM active (for example, during a call).
- ๐ The phone can be switched between SIM, loosening.
- ๐ฎ In games, the lags appear if the second SIM comes SMS call.
Decisions:
- Turn off the second. SIM, If you donโt use it all the time: Settings โ SIM-map โ [Second second SIM] โ Shut down.
- Set Network Priority for Main Network SIM: Settings โ SIM-map โ Network Priority (select the SIM, which should always be used 4G).
- If both SIM You need to, turn on the option Only 4G for SIM 1 (Poco-accessible F3/F4 s MIUI 13+).
โ ๏ธ Attention: On Poco X3 NFC older models of Dual hardware support 4G It means that if one of them is missing, SIM work 4G, The second automatically moves into 2G/3G. To return 4G basic SIM, may need to reboot.
๐ก
If you travel frequently, create separate profiles. APN For example, for a Megaphone in roaming, use APN Internet.megafon.ru instead of the standard Internet.
5. Optimization for games and streams: reducing ping and lag
For gamers and streamers, itโs not just download speed that matters, but connection stability. Even at 100 Mbps, high ping or jitter can make a game unplayable. There are several ways to improve these performances at Xiaomi Poco.
Ways to reduce ping:
- ๐ฎ Game mode: Enable in Settings โ Special facilities โ Game mode: It turns off background processes and optimizes the network for gaming.
- ๐ก Forced. 4G: In the engineering menu (#4636##) select LTE It's not a switch to the 3G, which increase delays.
- ๐ Disable Wi-Fi Assist: This feature automatically switches to mobile data when Wi-Fi is weak, but can cause ping spikes. โ Wi-Fi โ Additionally. โ Wi-Fi Assist.
For streamers (Twitch, YouTube, TikTok), stable apploade (recoil rate) is critical to improve it:
- Close all background applications, especially instant messengers and cloud services.
- In the stream settings, specify the bitrate 20% below the maximum (for example, if the speed of the apploade is 10 Mbit / s, set 8 Mbit / s).
- Use apps like NetGuard (without root) to block background traffic from other apps.
On Poco models F4 GT and F5 Pro has a hidden feature called Game Turbo 5.0 that allows you to prioritize traffic for specific games. To activate it, hold the game icon on your desktop. โ Choose "Game Turbo" โ "Network optimization".
๐ก
For online gaming, stable ping is more important than high download speeds. Even 20 Mbps with a ping of 30 ms will be more comfortable than 100 Mbps with a ping of 150 ms.
6.Firmware problems and their solution
Sometimes slow internet on Poco is linked to bugs in the Internet. MIUI. For example, in versions MIUI 12.5โ13.0 had a problem with the Rild module (responsible for mobile communications), which caused the speed to drop after 10โ15 minutes of active use. MIUI 14 This bug was fixed, but new nuances appeared.
Signs of program problems:
- ๐ Speed is normal immediately after restart, but drops after time.
- ๐ฑ The status bar is displayed 4G, but the actual speed is like 3G.
- ๐ง Reset APN Switching the network mode does not help.
Decisions:
- Update the firmware: Go to Settings โ The phone. โ Update system. If no updates, check manually on the site MIUI Downloads.
- Clear the cache of the communication module: Settings โ Annexes โ Application management โ Three points. โ Show system-based โ Telephone services โ Warehouse โ Clear the cache
- Reset network settings (does not delete data): Settings โ System system โ Resetting settings โ Resetting mobile network settings
If the problem persists, try to roll back to the old version. MIUI (For example, from 14th to 13th, you can find downgrad instructions on the forums. 4PDA or XDA Developers, but beware โ this can lead to data loss.
โ ๏ธ Attention: On Poco F1 with custom firmware (e.g. Pixel Experience) there may be problems with the module IMS, The one responsible for VoLTE and speed 4G+. If VoLTE support is missing after firmware, check the settings in Settings โ SIM-map โ VoLTE challenge.
7. Hardware problems: when the phone is to blame
If all software methods have been tried and the speed remains low, there may be hardware malfunctions.
- ๐ก Antenna module โ physical damage after falls or moisture.
- ๐ Slot SIM-cards โ oxidation of contacts or poor card pressing.
- ๐ Power module - with a discharged battery (<15%) The phone can artificially limit speed to save energy.
How to diagnose hardware problems:
- Check the speed with another. SIM-If the problem persists, it's the phone's fault.
- Look at this. SIM-Try to bend your contacts slightly (carefully, without bigotry).
- Run the antenna test: ##4636## โ Phone information โ Network information If in the Signal section the values are constantly changing with -90 dB -110 DBM, there may be problems with the antenna.
If the diagnosis confirmed hardware malfunction, repair options:
- ๐ ๏ธ Replacement of the antenna module costs 1,500โ3,000 โฝ service-centre.
- ๐ง Cleaning. SIM-lot - you can make yourself with alcohol and cotton swab.
- ๐ Replacement of the motherboard is an extreme case if the RF circuits are damaged (cost) ~50% of the price of the phone).
On Poco. F3 And newer antenna modules are often integrated into the back cover, and if the phone falls on the pavement, cracks near the camera may indicate that the antenna is damaged.
8.Alternative ways to speed up the Internet
If standard methods don't work, you can try non-obvious solutions, they don't guarantee results, but sometimes they give you 10 to 30 percent increase in speed.
Non-standard methods:
- ๐ Use it. DNS Google or Cloudflare: Settings โ Wi-Fi (or Mobile Network) โ Additionally. โ Private DNS โ Enter dns.google or 1dot1dot1dot1.cloudflare-dns.com This will not speed up the network itself, but will reduce delays when opening sites.
- ๐ Turn it off. IPv6 (sometimes conflicting with IPv4 for some operators: Settings โ Mobile network โ [Yours. SIM] โ Type APN โ IPv4 (instead IPv4/IPv6)
- โก Activate Developer Mode and Turn Off Animations: Settings โ The phone. โ Version. MIUI (press 7 times) โ Back to Settings โ Additionally. โ For developers โ This does not affect the network directly, but speeds up the system response, which subjectively improves the perception of speed.
For advanced users:
- ๐ ๏ธ Change. TTL (package lifetime) through ADB: adb shell settings put global captive_portal_detection_enabled 0 adb shell settings put global captive_portal_server This disables checks for โcaptive portalsโ (such as hotels) that can inhibit connection.
- ๐ก Forced to include carrier aggregation (CA): In the engineering menu (#4636##) find the option LTE CA And turn it on. That allows the phone to use multiple frequencies. 4G At the same time, if the operator supports).
โ ๏ธ Note: Change settings through ADB Or an engineering menu can cause the network to run in an unstable way. โ System system โ Backup.
๐ก
If you move frequently (for example, in transport), turn off automatic network selection and manually specify Only 4G. This will prevent the constant switching between 3G/4G, speed-eating.
