How to see the traffic on Xiaomi with MIUI 12: All methods and hidden functions

Control over the consumption of Internet traffic on Xiaomi smartphones with a shell MIUI 12 is a challenge that many users are concerned about, particularly for those who use limited mobile internet rates or want to track data usage in roaming, as opposed to newer versions of the shell (e.g., the mobile phone, MIUI 14 or HyperOS), the twelfth version has its own features in displaying statistics that are not always obvious.

In this article, we will not only examine basic methods of checking traffic through standard settings, but also hidden features that allow you to detail consumption by application, set limits and even export reports. You'll learn how mobile traffic is different from Wi-Fi, why the settings sometimes don't match the operator, and how to reset the meters without losing history. SIM-We have prepared a separate section with nuances of settings.

If you've ever faced a situation where the Internet suddenly ends up prematurely, or you just want to optimize its use, this guide will help you understand all the subtleties. MIUI 12.

Wherever MIUI 12 View the General Traffic of Mobile Internet

The fastest way to get general mobile Internet statistics is to use the built-in traffic counter in the settings. MIUI 12 The path to it is slightly different from the newer versions, so watch closely:

  1. Open β€œSettings” (the gear icon on the desktop or in the application menu).
  2. Go to SIM cards and mobile networks (some models may call it the Mobile network).
  3. Choose an active one SIM-card (if two of them).
  4. Slip on Traffic Use or Data Traffic.

Here you will see the consumption chart for the current billing period (usually a month), as well as the details by application. MIUI 12 shows data only for mobile Internet, and if you want Wi-Fi statistics, you'll have to look for them in another section, and we'll talk about that later.

⚠️ Note: If after updating to MIUI 12 Traffic section is gone – check if it’s hidden in the β€œAdvanced” menu (three dots in the top right corner of settings) SIM-Also make sure you don’t have third-party traffic-saving apps that can block the system meter.

In the same section, you can set up a limit warning and automatically shut down mobile Internet when you reach a preset threshold, for example, if your tariff includes 15 GB per month, you can set a 12 GB notification to connect an additional package.

πŸ“Š How often do you check your smartphone traffic?
Every day.
Once a week.
Only when the internet ends.
I never check.

How to check Wi-Fi traffic on Xiaomi MIUI 12

Statistics on data consumption via Wi-Fi MIUI 12 is hidden deeper than mobile traffic and is not always displayed correctly, because the system only takes into account connections that were active in the current session, and historical data can be reset after a reboot or disconnection from the network.

To see the current Wi-Fi spending:

  1. Go to Settings. β†’ Wi-Fi.
  2. Tap the name of the connected network (not the switch!).
  3. In the window that opens, select Network Use or Traffic Statistics.

Here you'll see two indicators:

  • πŸ“Š Total traffic – total consumption since the connection to this network.
  • ⏱️ Connection time – duration of session.

Unfortunately, MIUI 12 doesn't keep long-term Wi-Fi statistics like some third-party apps do (like NetGuard or GlassWire). If you want detailed reports, you'll have to use additional software, as we'll explain in one of the following sections.

πŸ’‘

To reset the Wi-Fi meter for a particular network, just forget it (click "Delete" in the connection settings) and connect again. The data will be zeroed.

Detailed traffic by application: who β€œeats” your Internet

One of the most useful tools in MIUI 12 -- you can see which apps are using the most traffic, and it helps you identify those voracious programs that are running in the background and are stealthily eating gigabytes:

  1. Go to Settings. β†’ SIM cards and mobile networks β†’ [choose SIM] β†’ Using traffic.
  2. Scroll down to the Application Traffic block.
  3. Click on any app from the list to see the details: background consumption, traffic in the foreground, and overall consumption.

In this section, you can not only view statistics, but also limit background activity for individual applications, for example, if Facebook or TikTok are constantly updated in the background, they can be blocked from using mobile Internet in the background:

  • πŸ”’ Click on the app in the list.
  • Activate the switch to Prohibit background data use.
  • πŸ“΅ For a complete limitation, turn off mobile data and Wi-Fi (if necessary).

Please note: some system applications (e.g. Google Play Services or Google Play Services) MIUI Daemon) can continue to use traffic even after blocking, because it is connected to the operating system, in such cases, only a complete disconnection of the mobile Internet or use of the Internet will help. VPN traffic-blocking.

Why do some apps show 0KB of traffic?
This can happen for three reasons: 1. The application did not use the Internet in the current billing period. 2. The data was reset after a system update or change. SIM-3. the application uses traffic through the VPN or proxy that is not counted by the system counter.

Setting limits and warnings about exceeding traffic

MIUI 12

  1. In the Traffic Usage section (the path described above), click on the three dots in the top right corner and select Traffic Limit Settings.
  2. Specify a total limit (e.g. 15 GB) and a warning threshold (e.g. 12 GB).
  3. Choose whether you want to turn off mobile internet automatically when you exceed the limit.
  4. Save the settings.

It's important to understand that these limits only work for mobile traffic, and for Wi-Fi, there are no such features, so you'll have to rely on third-party utilities or router settings.

Also in MIUI 12 it is possible to configure a cyclic counter that will be automatically reset on a certain date (for example, on the day of changing the tariff plan:

  1. In the same limit settings section, select Reset Date.
  2. Specify the number of the month when the counter should be reset (for example, the 1st day for most operators).

⚠️ Note: If you use two of these SIM-maps, limits and warnings are set separately for each, with total traffic in the statistics shown in aggregate, which can be misleading. To avoid confusion, disable mobile data for unused data. SIM customized.

Resetting the traffic counter without losing history

Sometimes you need to reset the traffic statistics manually, for example, after a change in the tariff plan or when you move to a new billing period. MIUI 12 this can be done without losing the history of past periods, but with one caveat: the system retains data only for one previous cycle.

To reset the meter:

  1. Open the Settings. β†’ SIM cards and mobile networks β†’ [choose SIM] β†’ Using traffic.
  2. Click on the three dots in the top right corner and select Reset Statistics.
  3. Confirm the action.

Once reset, the current data will be zeroed, but the graph will remain information from the past period (if any), which is convenient for comparing traffic consumption in different months.

If you need to clear the history completely (like before selling your phone), do the following:

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Find the Settings app (or Settings) and clear its Data and Cash.

⚠️ Attention: Settings will reset all user settings, including Wi-Fi connected networks, background restrictions and traffic limits. Use this method only as a last resort!

Hidden functions MIUI 12 for traffic control

In addition to the standard tools, the MIUI 12, there are some hidden features that help you manage your Internet consumption more flexibly:

  • πŸ” Traffic Saving Mode: Activated in Settings β†’ Battery and productivity β†’ Traffic saving mode: Limits background activity and reduces video streaming quality.
  • 🌐 Data Type Restriction: You can prohibit the use of mobile network settings 4G/5G for individual applications, leaving only 3G or 2G (saving).
  • πŸ“‘ Wi-Fi Priority over Mobile Data: Included in Settings β†’ Wi-Fi β†’ Additionally. β†’ Prioritize Wi-Fi: Helps avoid accidental switching to mobile internet.
  • πŸ”„ Automatic restart of statistics: If the date of reset is not suitable, you can manually change the beginning of the calculation period through the ADB-Teams (more on this below).

For advanced users, it is possible to manage traffic through ADB (For example, to reset the counter for a particular application, you can use the command:

adb shell cmd netpolicy reset-policy uid [ID_ of the annex]

Find out. UID Applications can be made using the adb shell dumpsys package command [name packet].

Important: MIUI 12 no built-in traffic report export function, but you can use Xiaomi’s Security app, where you can get day-to-week detail in the Traffic section.

πŸ’‘

Hidden settings MIUI 12 allow not only to track, but also actively manage traffic – from prioritizing Wi-Fi to blocking background activity for individual applications.

Third-party applications for traffic monitoring

If the built-in tools MIUI 12 You don't have enough, you can use third-party tools, which offer more flexible settings, detailed reports and cross-platform synchronization.-3 traffic control:

  • πŸ“Š NetGuard is a root-free traffic blocker that allows you to completely turn off the Internet for individual applications, maintains an activity log and works with the Internet. VPN.
  • πŸ“ˆ GlassWire – visualizes data consumption in the form of graphs, shows active connections and alerts you about suspicious activity.
  • πŸ” My Data Manager – tracks traffic across apps, Wi-Fi and mobile data, supports family control (for multiple devices).

When choosing a third-party application, pay attention to the following points:

  • πŸ”’ Ad blocker (some utilities, such as NetGuard, can perform this function in parallel).
  • πŸ“± Support for dualities SIM-Cards (not all programs work correctly with two SIMS).
  • πŸ“Š Possibility of exporting reports to CSV or Excel for analysis on PC.

One of the key benefits of third-party solutions is that you can track traffic in roaming. MIUI 12 does not always correctly account for data abroad, while GlassWire or My Data Manager maintain separate statistics for roaming.

Frequent problems and their solutions

When working with a traffic counter in MIUI 12 users often face some pretty big problems, and let's look at the most common ones and how to fix them.

1. The data in the settings do not match the operator

This is one of the most common complaints, and the reasons for the discrepancy may be as follows:

  • πŸ”„ The meter in the phone is reset manually or on schedule, and the operator keeps records continuously.
  • πŸ“‘ Some of the traffic is going through VPN Proxies that are not counted by the system.
  • πŸ”„ Background updates MIUI Google Play can consume data before the meter starts working (for example, immediately after a reboot).

Solution: synchronize the reset date in the phone with the operator's change of tariff period, and you can also use third-party apps to parallel record.

2. The meter is resetting on its own.

If the statistics are reset without your participation, check:

  • πŸ”„ Is automatic update not enabled? MIUI (Sometimes it resets some settings).
  • πŸ“± Are you using cache cleaner applications (such as Clean Master) that may affect system data.
  • πŸ”„ Haven't you changed? SIM-map APN (This can lead to zero statistics).

3. no Wi-Fi traffic is shown

If the Wi-Fi statistics section is missing:

  • πŸ”„ Reconnect to the network (sometimes helps to just turn off and turn on Wi-Fi).
  • πŸ“± Check if the section is hidden in the additional settings (three points in the Wi-Fi menu).
  • πŸ”„ Update. MIUI Up to the latest available version for your model (in some builds this bug has been fixed).

πŸ’‘

If traffic problems are repeated regularly, try calibrating the meter: reset the statistics, restart the phone and wait for a new billing period.

Can I? MIUI 12 Track traffic by hour or day?
In standard settings MIUI 12 hours of detail is missing, but you can use third-party apps like GlassWire or NetGuard that provide hourly and daily statistics. Xiaomi's Security app also has a Traffic section with more detailed reports.
Why do some apps (like Telegram) show 0KB of traffic when I use them?
This may be because the application uses WebRTC or other protocols that are not counted by the system counter, and there may be an error in the application itself, so try reinstalling it. VPN, It masks the actual consumption of data.
How to transfer traffic statistics to the new Xiaomi phone?
Unfortunately, MIUI 12 does not support export/import traffic statistics, but you can: Take screenshots of charts and notes, use third-party applications (such as My Data Manager) that are synced through your Google account. Manually record key data (total consumption, limits) and transfer it to a new device.
Can I restrict traffic to individual roaming apps?
Yeah, in MIUI 12 have separate settings for roaming: Go to Settings β†’ SIM cards and mobile networks β†’ [choose SIM] β†’ Data roaming. Activate the switch Limit background traffic. To completely limit, turn off Mobile data in roaming or adjust the limits manually. You can also use NetGuard to block specific applications in roaming.
Why After Updating to Update MIUI 12 missing traffic section?
This is a known problem with some builds. Try the following steps: Clear the cache and app data Settings (Settings) β†’ Annexes β†’ Application management β†’ Settings β†’ Clear the data. Check if the section is hidden in the additional menu (three points in the settings). SIM-If nothing helps, reset the network settings: Settings β†’ System system β†’ Resetting settings β†’ Reset network settings. In extreme cases, you may need to flash the device or roll back to the previous version. MIUI.
