Smartphones Huawei shell-based EMUI collect a huge amount of data about your activity: from visited sites to the list of installed applications. This information takes up memory space, slows down your device, and can be a privacy risk. The problem is especially pressing for owners of models P50 Pro, Mate 60 or budget Nova 11, where the amount of internal memory is often limited to 128 GB.

Unlike the "pure" Androidshell Huawei has unique settings for storing history, and some functions (for example, Huawei Mobile Services) require separate cleaning. In this article you will find current methods of deleting history for EMUI 13/14, including hidden system logs that are not cleared by standard methods. We will also reveal the nuances of working with models without Google services and show how to avoid repeated accumulation of unnecessary data.

1. Clearing browser history Huawei Browser

The built-in browser Huawei Browser (previously known as Huawei Mobile Browser) saves your browsing history, cookies and cache by default. On models with EMUI 13+ the storage algorithm has changed: now the data is synchronized with the cloud Huawei Cloudif the corresponding option is enabled. This means that simply deleting through your browser settings may not be enough.

To completely erase traces of activity:

  • 📱 Open Huawei Browser and tap on the three dots in the lower right corner
  • 🔍 Select History → Clear data
  • ⏳ Set the period All time and check all the boxes (including Passwords and forms)
  • ☁️ Go in Settings → Huawei Cloud → Synchronization and disable Browserif you are not using the cloud
⚠️ Attention: On some firmware Huawei After clearing the history, the browser can automatically restore some of the data from the backup. To avoid this, disable Automatic recovery in the cloud settings before cleaning.

For users using Google Chrome on models with GMS (for example, Huawei P30 or Mate 20 Pro), the path will be different:

  1. Open Chrome and go to ⋮ → History → Clear data
  2. Select Advanced mode and set the period For everything time
  3. Make sure that the items Cookies and site data are checked and Cached images

2. Deleting call and SMS history

Call logs and messages take up less space than the browser cache, but may contain sensitive information. IN EMUI 14 a function has appeared that automatically deletes old entries, but it does not work on all models: For manual cleaning: Smart cleaning, which automatically deletes old entries, but it does not work on all models. For manual cleaning:

For call history:

  • 📞 Open the application Phone
  • 📋 Tap on three dots → Call log
  • 🗑️ Select Delete → All calls or mark specific entries

For SMS:

  • 💬 Go to Messages
  • 🔍 Click on the three dots → Settings → Clear messages
  • ⏳ Select a period (for example, Older than 30 days) or delete everything
Data type Where is stored Max. volume (approx.) Auto clearing
Log calls /data/com.android.providers.contacts/databases/contacts2.db up to 50 MB Available in EMUI 14+
SMS/MMS /data/com.android.providers.telephony/databases/mmssms.db up to 200 MB Only by time
Call logs (system) /data/log/call_log* up to 10 MB No

On models with dual SIM cards (for example, Huawei P40 Dual SIM) the call history is stored separately for each slot. To clear everything completely, repeat the procedure for each. SIM.

💡

If you need to save important SMS before cleaning, export them via Settings → Export messages to an .xml file. This file can be opened on a PC or restored later.

3. Clearing application history and Google Play

System logs and the history of installed applications are stored in several places. On devices with Huawei Mobile Services (HMS) (without Google), data about downloaded apps can be found in AppGallery. data-i="126">(for example, Google Mobile Services (GMS) (For example, Huawei Mate 30 Pro early batches) - in Google Play Market.

For AppGallery:

  • 📦 Open AppGallery → profile → Settings
  • 📜 Select Download history → Delete
  • 🔄 To completely clear the cache, go to Settings → Applications → AppGallery → Storage → Clear cache

For Google Play (if available):

  • 🛒 Open Play Market → profile icon → Manage applications
  • 📋 Go to the tab Installed → Not used to search for unnecessary apps
  • 🗑️ To clear the update history, use play.google.com/settings in the browser (account login required)
⚠️ Attention: On some firmware Huawei after deleting an application via AppGallery, its data may remain in the folder /Android/data/[package_name]. For complete cleaning, use a file manager with root access or a standard application Cleaning (broom icon in the menu).

4. Hidden history: system logs and debug data

Even after cleaning the browser and applications, data-i="157">remains in the system, which can occupy hundreds of megabytes. These files are created for diagnostics, but are rarely needed by ordinary users. They can be found along the path. debug logs, which can take up hundreds of megabytes. These files are created for diagnostic purposes, but are rarely needed by ordinary users. IN EMUI they can be found along the way /sdcard/log/ or /data/log/ (access rights required).

For safe cleaning:

  1. Open the standard application Files (or any file manager)
  2. Go to Internal memory → log
  3. Select all files with extensions .log, .txt, .dmp
  4. Delete them, but do not touch folders hprof and anr —cleaning them can lead to failures

For advanced users, there is a way to clear them through ADB (required developer mode enabled):

adb shell

su


rm -rf /data/log/*


rm -rf /sdcard/log/*


rm -rf /data/anr/*


rm -rf /data/tombstones/*

These commands will delete all debugging logs, including data on application crashes. After execution, reboot the device.

What happens if you delete all logs?

Without critical logical files (tombstones, anr), the system may behave unstable the next time the application crashes. However, for most users this will not cause problems - the logs are restored automatically if necessary. The main thing is not to delete files in the /system/log/ or /vendor/log/folders, as this may disrupt operation. firmware.

5. Automatic cleaning: optimizer setting

Huawei built into the EMUI tool Optimizer (previously Phone Manager), which can automatically clear unnecessary data. works ineffectively. To configure it correctly:

  • ⚙️ Go to Settings → Battery → Optimizer (or find the "broom" icon in the menu)
  • 🔄 Enable Auto-clean and set the schedule (recommended Every week)
  • 📊 In section Storage & Performance check:
    • 🗑️ Residual files (remains after deleting applications)
    • 📥 Downloads (if you do not store important files)
    • 📊 System cache
  • 🚫 Disable Cleaning photosif you do not want to lose media files

On models with NM Card (hybrid slot for a second SIM or memory card), the optimizer may offer transfer rarely used applications to the card. This feature is useful, but remember that applications on the SD card are slower.

💡

Automatic cleaning through the Optimizer removes up to 1.5 GB of unnecessary data per month, but does not affect browser history and system logs. For complete cleaning, use manual methods from the previous sections.

6. Factory reset: last resort

If you need completely. erase all data (for example, before selling your phone), perform a factory reset. On Huawei this is done differently than on other Android devices:

Method 1: Through settings

  • ⚙️ Go to Settings → System and updates → Reset
  • 🔄 Select Reset all settings or Reset to factory settings
  • 🔐 Enter the password (if set) and confirm

Method 2: Through Recovery (if the phone does not turn on)

  • 🔌 Turn off the device
  • 🔘 Press Volume up + Power until the logo appears Huawei
  • 📱 In the recovery menu, select Wipe data/factory reset (volume button control)
⚠️ Attention: On models with Huawei Mobile Services after resetting, you may need to re-link your account Huawei IDIf you have forgotten your password, restore it in advance on the website huawei.com. since without it the device will not be activated.

After the reset:

  • 📱 The phone will reboot and offer initial setup
  • ☁️ If synchronization with Huawei Cloudwas enabled, the data can be restored automatically
  • 🔒 To avoid this, skip logging into your account when you first turn on

7. How to prevent history from accumulating again

To avoid clearing the history every week, set your device to minimal logging:

For browser:

  • 🌐 In Huawei Browser disable Saving history in privacy settings
  • 🔒 Use mode Incognito for sensitive sites

For the system:

  • ⚙️ Disable USB debugging in the developer settings (if not using)
  • 📊 Limit background activity of applications in Settings → Applications → Autorun
  • ☁️ Disable synchronization of unnecessary data in Huawei Cloud

For applications:

  • 📦 Regularly check the section Settings → Applications → Storage for the presence of a large cache
  • 🗑️ Remove unused apps through Optimizer → Memory clearing

On models with EMUI 14 a function has appeared Confidential modethat blocks application access to history and location. To enable it:

  1. Go to Settings → Privacy → Confidential mode
  2. Activate the switch and add applications to exceptions
💡

If you often use public Wi-Fi networks, enable VPN in settings Huawei Browser. This will not only protect your history from interception, but will also block trackers that collect data about your activity.

FAQ: Frequently asked questions about clearing history on Huawei

The exception is if you synchronized contacts with a Google or Huawei account: in this case, the history may be partially saved in the cloud.

Why does the history appear again after clearing the browser?

This happens due to synchronization with Huawei Cloud. To avoid restoring the history:

  1. Open Settings → Huawei ID → Cloud → Synchronization data
  2. Disable the option Browser
  3. Clear the history again
