Where does the traffic on Xiaomi devices go: 7 hidden reasons and ways to save money

Did you notice that your Xiaomi suddenly started eating gigabytes of mobile traffic or home internet for no apparent reason?It's not paranoia - many users are faced with smartphones, TVs and even the brand's smartwatches consuming data in the background, sometimes exceeding tariff limits by many times. Unlike Apple or Samsung, Xiaomi devices are often criticized for aggressive data collection policies and hidden processes that are difficult to track without special tools.

In this article, we will not just list the standard tips like “turn off automatic updates”, but will analyze the specific mechanisms that consume traffic on Xiaomi devices – from advertising modules in MIUI to hidden synchronization services. You will learn how to turn off up to 80% of background traffic consumption without losing functionality, which applications are most often to blame, and why even a turned off Mi TV can pull data from the network. All instructions are relevant for 2026 and tested on the latest versions of firmware.

1. Hidden system and application updates

The most obvious, but often underestimated, reason for traffic is automatic updates, and unlike iOS, where updates are only downloaded via Wi-Fi (unless you change your settings), MIUI and HyperOS allow updates to be downloaded by default over the mobile network, and not just firmware, but also:

• 📱 System application updates (Mi Browser, Security, Gallery, etc.)
• 🖥️ Branded services (Mi Cloud, Mi Video, Mi Music)
• 📺 TV firmware (even if you don't use Smart TV)

For example, a firmware update for the Xiaomi 13 Pro can weigh 2.5-3 GB, and the update package for the Mi TV Q2 can weigh up to 1.2 GB. If the device downloads them through 4G, it will easily “eat” half the monthly limit. Worst of all, Xiaomi does not always notify the user about the start of the download – the process can start at night or when connecting to a charge.

To disable background updates:

1. Go to Settings → About Phone → Update MIUI (or HyperOS for new models).
2. Click on the three dots in the top right corner and select Update Settings.
3. Turn off the option Automatic download via mobile data.
4. For apps: Settings → Applications → Application management → Auto Update and select Only via Wi-Fi.

💡

If you are using Mi TV Stick or Xiaomi TV, check the update settings in the System → Software Update menu. Even if the device is turned off, it can download firmware in standby mode!

2. Advertising modules and analytics in MIUI

Xiaomi has long been known for embedding ads directly into the interface, but few people know that these ad modules not only show banners, but also actively consume traffic to:

• 📊 Download personalized ads (based on your activity).
• 🔄 Updates to advertising campaigns (e.g., Mi Browser or Security).
• 📡 Send device usage data to Xiaomi servers (even if you have disabled Personalization).

According to a study by Privacy International (2023), Xiaomi’s smartphone sends 5-15MB of data to the company’s servers on average per day for analytics and advertising only, which is 150-450MB per month – and this does not include the actual download of advertising materials! For example, a banner in the Mi Browser can weigh up to 2-3MB (due to high-quality images).

How to turn off advertising and analytics:

Disable personalization in Settings → Xiaomi Account → Mi Account → Advertising Personalization

Remove or freeze the Msa (Main Server Application) application via ADB

Disable “Recommendations” in Mi Browser and Mi Video

Use a DNS blocker (e.g., 1.1.1.1 or 9.9.9.9)

-->

⚠️ Warning: Deleting the Msa application may disrupt some system functions, such as push notifications. Back up your data before doing so!

3. Background synchronization of Mi Cloud and other services

Mi Cloud is not just cloud storage, it's a whole range of services that sync in the background, and even if you don't use backups, it can send to Xiaomi's servers:

• 📁 System logs (for diagnostics).
• 📍 Geolocation data (if Find Device is enabled).
• 📱 Contact lists and SMS (if synchronization is activated).
• 🖼️ Miniature photos (even if the originals are not downloaded)

According to our tests, the Mi Cloud can consume up to 30-50 MB per day if all sync options are turned on, especially voracious photos: even if you turn off automatic download, the system can send previews (smaller copies of images) to the server to speed up viewing in the gallery.

To reduce traffic consumption:

1. Go to Settings → Xiaomi Account → Mi Cloud.
2. Turn off sync for unnecessary data (e.g. Notes, Bookmarks, Calendar).
3. In the Gallery section, select Download only over Wi-Fi.
4. Turn off Auto Boot for Mi Drive and Mi Docs.

4. Vampire Apps: Who is Most at fault?

Some of Xiaomi’s standard apps consume traffic even when you’re not using them. Here are the top -5 voracious services:

1. Mi Video and Mi Music: These apps download album covers, trailers and recommendations in the background, for example, Mi Video can pull up to 100MB/day if you don't turn off autoplay previews.

To limit these applications:

• 🛡️ Go to Settings → Applications → Application Management, select the right one and turn off Background data.
• 📵 For Mi Browser, turn off Page Preload and News Feed.
• 🎮 Remove or freeze the Game Turbo if you are not playing.

💡

Even if you don't run an app, it can consume traffic through background processes. Check the Data Use section in the settings at least once a week!

5. Xiaomi TVs: Why do they "eat" traffic even when turned off?

If you have a Mi TV, Mi Box or Mi TV Stick, be prepared for these devices to consume data 24/7. Even when switched off (Standby mode) Xiaomi TVs:

• 📡 Supports a connection to servers for push notifications.
• 🔄 Updates weather, news and stock quote widgets.
• 🎬 Download cover art for recommended movies (even if you don't watch TV).
• 📦 Check for updates for pre-installed apps (Netflix, Prime Video, YouTube).

According to RTINGS.com, the Xiaomi Mi TV Q1E can consume up to 50-100MB/day on standby, and if the TV is on but not in use (e.g., it works as wallpaper), consumption can reach 1-2GB/day due to background loading of content.

How to reduce traffic on Mi TV:

1. Turn off automatic app updates: Settings → Apps → Auto Update → Wi-Fi only.
2. Remove unnecessary widgets from the home screen (they update data in the background).
3. Turn off Content Recommendations in Settings → Account and Security → Personalization.
4. Use an energy saving mode (Settings → Energy saving) that limits background activity.

⚠️ Warning: If you connect a TV to a mobile hotspot (for example, via a smartphone), it can eat all the traffic in a few hours!

6.Smart Devices and IoT: How a Robot Vacuum Cleaner Drifles Your Traffic

If you have Xiaomi smart devices (Mi Robot, Yeelight light bulbs, Aqara outlets), they also consume Internet traffic, not only when you are operating them, but also in the background:

• 🤖 Robot vacuum cleaner sends room maps and cleaning logs to Xiaomi servers (10–50 MB/day).
• 💡 Smart light bulbs synchronize schedules and update firmware (5–20 MB/week).
• 🔌 Sockets and sensors send data on energy consumption and state (1-5 MB/day).

The main problem is that these devices don’t work locally — even if you turn off cloud sync in Mi Home, they’ll still try to connect to Xiaomi’s servers to check for updates.

How to reduce traffic consumption:

1. In the Mi Home app, turn off Cloud Sync for unnecessary devices.
2. Set up Local Control (if supported by your model).
3. Limit the background activity of the Mi Home app in your smartphone settings.
4. For a robot vacuum cleaner, turn off map download to the server: Device settings → Map → Save in the cloud.

7.How to Track and Block Traffic Leakage

To find out exactly where the traffic is going, use these tools:

• 📊 Built-in monitoring: Settings → Network and Internet → Data usage. Here you can see which applications are spending the most.
• 🔍 Third-party applications: NetGuard, GlassWire or Data Usage Monitor show detailed statistics on each process.
• 🛡️ Traffic blockers: Blokada or AdGuard may restrict background activity of system applications.
• 🌐 DNS- filters: Use 1.1.1.3 (block malicious domains) or 94.140.14.14 (AdGuard DNS).

If you have detected suspicious activity:

1. Check if other gadgets are connected to your device (for example, via Mi Share or Hotspot).
2. Use adb to disable system services (power users only!). For example, the command: adb shell pm disable-user --user 0 com.miui.analytics will disable analytics collection.
3. Reset network settings: Settings → Network and Internet → Reset your Wi-Fi, mobile network and Bluetooth settings.

💡

If the traffic goes away even when the device is not in use, check for viruses. Some malware masquerades as Xiaomi system processes (e.g. com.android.providers).
