Honor 7 is one of the most popular mid-class smartphones from Huawei, released in 2015. Despite its advanced age, the device is still actively used thanks to its reliable hardware base and the ability to install custom firmware. However, over time, even this device begins to โ€œslow down,โ€ and the reason most often becomes overcrowded cache temporary files that the system and applications create to speed up work.

If your Honor 7 became slower to respond to commands, spontaneously closes applications or issues a notification about lack of memory - itโ€™s time time to clear the cache. In this article we will analyze all the current methods: from standard tools Android 5.0 Lollipop (which the device worked on out of the box) to methods for custom firmware based on Android 7+. We will pay special attention to the nuances associated with the architecture HiSilicon Kirin 935 and the proprietary shell EMUI 3.1/4.0.

Why do you need to clear the cache on Honor 7?

The cache is not just โ€œgarbageโ€, but an important element of optimization. However, on Honor 7 with its modest by modern standards 3 GB of RAM i 16/64 GB of ROM a full cache can cause serious problems:

  • ๐Ÿข Slowdown: the system spends time processing outdated temporary files instead of current data.
  • ๐Ÿ”„ Spontaneous reboots: when there is not enough memory, Android forcibly closes processes, which can lead to crashes.
  • ๐Ÿ“ฑ Errors in applications: cache may conflict with updated versions of apps (especially important for Google Play Services and Huawei Mobile Services).
  • ๐Ÿ“‰ Reducing the service life of the drive: constant overwriting of cache files accelerates wear of flash memory (especially critical for budget models with eMMC instead of UFS).

The Honor 7 cache is divided into three types:

  1. System cache โ€”Android OS and shell files EMUI.
  2. Application cache โ€”temporary data of individual apps (for example, downloaded pictures in Instagram or card cache in Google Maps).
  3. Dalvik cache - optimized files for the virtual machine ART (relevant for Android 5.0+).
โš ๏ธ Attention: On Honor 7 with custom firmware (for example, LineageOS), the cache structure may differ. Some clearing methods described below may require rights. root.

Method 1: Clearing the cache of individual applications via settings

The safest and recommended method is to manually clear the cache for specific apps. This does not affect system files and does not require administrator rights.

Instructions for EMUI 3.1/4.0 (stock firmware):

  1. Open Settings โ†’ Application Manager (or Applications).
  2. Scroll to the desired application (for example, Facebook or Chrome) and tap on it.
  3. Click Memory โ†’ Clear cache.
  4. For complete clearing (including application data), select Clear data, but note that this will reset all app settings.

On custom firmware (for example, Resurrection Remix) the path may be different:

Settings โ†’ Applications and notifications โ†’ Show all applications โ†’ [Select application] โ†’ Memory and cache โ†’ Clear cache

๐Ÿ—‘๏ธ Social networks (Facebook, VK, Instagram)

๐ŸŽฎ Games (especially with heavy graphics)

๐ŸŒ Maps and navigators (Google Maps, Yandex.Maps)

๐Ÿ“ท Gallery and photo editor (thumbnail cache)

๐ŸŽต Music applications (album cover cache)-->

To speed up the process, you can sort applications by cache size:

  1. Tap on the three dots in the upper right corner. Application Manager tap on the three dots in the upper right corner.
  2. Select Sort by size.
  3. Clear the cache for applications that take up more 100 MB.
โš ๏ธ Attention: Do not clear the cache for Google Play Services, Huawei Mobile Services i System UI unless absolutely necessary - this may cause interface malfunctions.

Method 2: Complete cache clearing via Recovery Mode

If the phone is very slow or does not boot in normal mode, clearing the cache via Recoverywill help. This method resets the system cache, but does not affect user data. Dalvik cache and system cache, but does not affect user data.

Instructions for stock Honor 7 Recovery:

  1. Turn off the phone.
  2. Press simultaneously Volume up + Power and hold 10-15 secondsuntil appears logo EMUI.
  3. In the menu Recovery (controlled by the volume and power buttons) select Wipe cache partition.
  4. Confirm the action and wait for the process to complete.
  5. Select Reboot system now to reboot.

For custom recovery (TWRP, OrangeFox):

  1. Boot into TWRP (same as stock recovery, but a different combination of buttons may be required).
  2. Tap Wipe โ†’ Advanced Wipe.
  3. Tick the boxes Dalvik / ART Cache and Cache.
  4. Swipe to confirm and wait for completion.
Recovery type What is cleared Procedure time Are root access required?
Stock (EMUI) System cache, Dalvik cache 2-5 minutes No
TWRP System cache, Dalvik cache, application cache (optional) 1-3 minutes No
OrangeFox The same + the possibility of selective cleaning for individual users (MultiROM) 1-4 minutes No
What to do if Recovery does not open?

If the phone does not respond to the button combination, try:

1. Connect the charger and try again (sometimes it helps with a low battery).

2. Use the ADB command: adb reboot recovery (requires USB debugging enabled).

3. If custom recovery is installed, check that it is correct. combinations - for some firmware this is Volume down + Power.

4. As a last resort, you may need to flash Recovery via Fastboot.

Method 3: Using third-party applications for cleaning

If manual cleaning seems tedious, you can use specialized ones utilities. For Honor 7 suitable:

  • ๐Ÿงน CCleaner โ€”a classic cleaner with support for older versions of Android. Allows you to delete cache, residual files and analyze startup.
  • ๐Ÿ” SD Maid โ€”an advanced tool with a search function for โ€œjunkโ€ files (including cache Google Play system logs).
  • ๐Ÿ“Š Files by Google โ€”an official application from Google with a simple interface and the โ€œMemory Cleanupโ€ function.
  • ๐Ÿ› ๏ธ All-In-One Toolbox โ€”a combine with cache clearing, RAM optimization and startup management.

Example of cleaning via SD Maid:

  1. Install the application from Google Play or APKMirror (if Play Services is not working).
  2. Run SD Maid and provide memory access rights.
  3. Go to the tab CorpseFinder (search residual files) or AppCleaner (clearing the application cache).
  4. Tick the unnecessary files and click Run.
โš ๏ธ Attention: Some applications (for example, Clean Master) can aggressively optimize the system, which on Honor 7 its limited resources can lead to the opposite effect - additional load on the processor. Give preference to utilities with minimalist functionality.

Method 4: Clearing the cache via ADB (for advanced users)

If you have access to ADB (Android Debug Bridge), you can clear the cache using the command line. This method is useful if the phone is buggy and does not respond to touches.

Instructions:

  1. Install ADB on your computer (for example, via Platform Tools from Google).
  2. Connect Honor 7 via USB and enable USB debugging in Settings โ†’ For developers.
  3. Open the command line (or Terminal on macOS/Linux) and enter:
adb devices

(your device should be displayed)

adb shell pm list packages -f

(will show a list of all applications with paths to their cache)

To clear the cache of a specific application (for example, com.facebook.katana):

adb shell pm clear com.facebook.katana

To clear Dalvik cache:

adb shell rm -r /data/dalvik-cache/*

To completely clear the cache all applications (requires root):

adb shell su -c "rm -r /data//cache/"
๐Ÿ’ก

Before using ADB, create a backup copy of your important data. Command pm clear not only clears the cache, but also resets the application settings!

Method 5: Reset to factory settings (last resort)

If none of the methods helped, and the phone continues to slow down, the only option left is Hard Reset a full reset to factory settings. will delete all data, including applications, photos and accounts, so make a backup copy first.

Instructions:

  1. Go to Settings โ†’ Backup and reset โ†’ Reset settings.
  2. Select Reset all settings (or Wipe data/factory reset to Recovery).
  3. Confirm the action and wait for the reboot (will take 5-10 minutes).

After the reset:

  • ๐Ÿ”„ Restore the data from the backup (if it was created via HiSuite or Google Account โ†’ Launching applications Google Account).
  • ๐Ÿ“ฅ Install only necessary applications - avoid downloading โ€œjunkโ€.
  • ๐Ÿ”ง Disable startup of unnecessary apps in Settings โ†’ Battery โ†’ Launch applications.
โš ๏ธ Attention: On Honor 7 with an unlocked bootloader (bootloader), resetting to factory settings can lead to blocking the device (requirement FRPIf you have forgotten your account data Google/Huawei, use FRP Bypassmethods for your version EMUI.

How to prevent the cache from filling up quickly in the future?

To reduce the need for cleaning, follow these tips:

  • ๐Ÿ“ต Limit background activity: Settings โ†’ Battery โ†’ Launch applications disable startup for unnecessary apps.
  • ๐Ÿ”„ Update applications: outdated versions often create more cache due to unoptimized code.
  • ๐Ÿ—‘๏ธ Use โ€œlightโ€ versions of applications: for example, Facebook Lite, Messenger Lite, Twitter Lite.
  • ๐Ÿ“ Move the cache to an SD card: some applications (for example, Google Chrome) allow you to save the cache to an external drive.
  • ๐Ÿ”„ Restart your phone regularly: this clears RAM temporary files that are not always deleted automatically.

On Honor 7 with firmware based on Android 5.0-6.0 cache Google Play Services can take up to 1-2 GB. To reduce its size:

  1. Go to Settings โ†’ Applications โ†’ Google Play Services โ†’ Storage.
  2. Click Manage space โ†’ Clear all data.
  3. Reboot your phone.

Clear the cache at least once a month if you actively use social networks and instant messengers. For Honor 7 with 16 GB of memory, the optimal โ€œthresholdโ€ for filling the cache is 1-1.5 GB.

Frequent questions (FAQ)

โ“ Why do some applications run slower after clearing the cache?

This is normal: applications need time to restore temporary files (for example, loading thumbnails in the gallery or the map cache in the navigator). data-i="270">โ“ Is it possible to clear the cache without losing data?

โ“ Is it possible to clear the cache without losing data?

Yes, if you use the methods from Method 1 (clearing the cache of individual applications) or Method 2 (Wipe cache partition in Recovery) These actions do not affect user files. However, cleaning Dalvik cache via ADB or factory reset may result in data loss.

โ“ Why does the cache fill up on Honor 7 faster than on new phones?

There are several reasons:

  1. eMMC memory (instead of UFS in modern smartphones) processes write/delete operations more slowly.
  2. Android 5.0-6.0 is less optimized for cache management compared to new versions.
  3. The limited amount of RAM (3 GB) forces the system to make more active use of the disk cache.

Solution: install custom firmware based on Android 7+ (for example LineageOS 14.1) - this will improve memory management.

โ“ What to do if after clearing the cache the phone stops turning on?

Probable causes and solutions:

  • ๐Ÿ”‹ The battery is low โ€” connect the charger and wait 10-15 minutes.
  • ๐Ÿ”„ Failure when clearing the Dalvik cache โ€”boot into Recovery and repeat the procedure.
  • ๐Ÿ› ๏ธ Damage to system files โ€”reset to factory settings or reflash the phone via Fastboot.

If the phone does not respond to buttons, try the combination Volume up + Volume down + Power to force a reboot.

โ“ How to clear the cache for system applications (for example, Phone or Messages)?

System applications in EMUI are often hidden from manual cleaning. To access them:

  1. Activate Developer mode (tap 7 times Build number to Settings โ†’ About phone).
  2. Go back in Settings โ†’ For developers and enable USB debugging.
  3. Connect your phone to the PC and use the ADB command:
    adb shell pm clear com.android.contacts

    (replace com.android.contacts with the package of the desired application).

Attention: clearing the system application cache may cause to malfunctions in their operation!
