WhatsApp is one of the most popular instant messengers in the world, but over time it turns into a real “black box” of your smartphone. Photos, videos, voice messages, stickers, and backups silently take up gigabytes of memory, slow down your phone, and can even cause crashes. If your Androiddevice begins to slow down, and a notification about low memory appears too often, it may be the culprit WhatsApp.

Many users mistakenly think that it is enough to simply delete unnecessary chats. In fact, the messenger stores data in several places: application cache, internal storage, Google Drive (for backups) and even system foldersthat are not visible through the standard file manager. In this article we will look at all cleaning methods from basic to advanced, including hidden settings and working with technical files.

1. Estimation of occupied space: how much does your WhatsApp weigh?

Before you start cleaning, you need to understand what data is taking up space. WhatsApp it can “weigh” from several hundred megabytes to tens of gigabytes - it all depends on the activity of use.

To check the amount of occupied memory:

  1. Open Settings → Applications → WhatsApp → Storage.
  2. Pay attention to two indicators: application memory (APK + data) and cache.
  3. For a detailed analysis, go to Whatsapp settings → Storage and data → Storage management.

Here you will see the distribution by file type (photos, videos, GIFs, documents) and chats. For example, a group with active correspondence for a year can occupy up to 5-7 GB only due to media fileseven if the messages themselves have long been deleted.

Once every six months
Only when the memory runs out
Never cleared

2. Deleting WhatsApp cache: a quick way to free up space

Caches are temporary files that WhatsApp creates to speed up work (for example, photo thumbnails or pre-loaded stickers). Over time, the cache grows to 1–3 GB, but it can be safely deleted without losing important data.

Instructions:

  • 📱 Go to Android Settings → Applications → WhatsApp → Storage. if it is installed..
  • 🧹 Click "Clear cache" (not to be confused with "Clear data" - this will delete all messages!).
  • 🔄 Repeat for WhatsApp Business, if installed.

The cache will be restored automatically the next time you use it, but its size will be temporarily reduced. This method does not delete media files from chats is only service data.

⚠️ Attention: If after clearing the cache WhatsApp started to work slower (for example, stickers take longer to load), this is normal. The application needs time to restore temporary files.
💡

To prevent the cache from growing too quickly, disable auto-downloading media in WhatsApp settings: Storage and data → Autoload media. Select "Only over Wi-Fi" or "Never".

3. Cleaning media files: photos, videos and documents

The main memory hog is the media files that you receive and send. Even if you deleted a chat message, the files themselves may remain in the folder WhatsApp/Media on the internal drive.

How to delete unnecessary files:

  • 🖼️ Use the built-in storage manager: Whatsapp settings → Storage and data → Manage storage. Here you can sort files by size and type (for example, show all videos >50 MB).
  • 🗑️ Manually delete folders: 
    /sdcard/WhatsApp/Media/WhatsApp Images

    /sdcard/WhatsApp/Media/WhatsApp Video
    

    /sdcard/WhatsApp/Media/WhatsApp Animated Gifs

    Note: Folder WhatsApp can be located in internal memory or on an SD card.
  • 🔍 To search for duplicates, use applications like Files by Google or SD Maid.

If you are afraid of deleting something important, first transfer the files to your computer or to the cloud. For example, photos from chats can be copied to Google Photos, and documents - to Google Drive.

File type Medium size Can I delete? How to restore
Photos 2–5 MB per piece Yes, if there is a backup copy From chat (if not deleted) or backup copy
Video 10–100 MB per piece Yes, but be careful Only from backup
Voice messages 0.5–2 MB per minute Yes Resend or restore from a copy
Documents (PDF, APK) Various (from 100 KB to gigabyte) Yes, if not needed Resend
What to do if the WhatsApp folder is not visible in the file manager?

Enable the display of hidden files in the manager settings (for example, in Files by Google: ⋮ → Settings → Show hidden files). If there is no folder, check whether WhatsApp has been transferred to the SD card (in the application settings).

4. Deleting backups: how to free up Google Drive

WhatsApp automatically creates backup copies of chats in Google Driveand they can take up up to 15 GB your cloud storage. If the copies are old or unnecessary, you can delete them.

Instructions for cleaning Google Drive:

  1. Open Google Drive in the browser.
  2. In the search bar, enter app:WhatsApp - all backups will be displayed.
  3. Select unnecessary files and click "Delete" (or "Trash" → "Empty Trash" for complete deletion).

To disable automatic backup:

  • 🔄 Go to WhatsApp Settings → Chat → Backup chats.
  • 🚫 Select "Never" or reduce the frequency (for example, once a month instead of daily).
⚠️ Attention: Deleting a backup from Google Drive will make it impossible to restore chats when reinstalling WhatsApp. If you plan to change your phone, first save a copy manually!

5. Complete cleaning: resetting WhatsApp to factory settings

If WhatsApp it is unstable (for example, it constantly crashes or does not send messages), you may need Full reset. This will delete all application data, including settings and cache, but will not affect media files in the folder WhatsApp/Media.

How to reset WhatsApp:

Save important chats manually (export via email)

Download a backup copy from Google Drive (if needed)

Remember or take a photo of the notification settings

Check that you have access to the SIM card (to verify the number)-->

  1. Go in Android Settings → Applications → WhatsApp.
  2. Click "Storage" → "Clear data" (not cache!).
  3. Confirm the action. The application will return to the state "as after installation".
  4. Run WhatsApp again and restore chats from a backup copy (if necessary).

After the reset:

  • 🔧 Configure auto-loading media (Storage and data → Autoload media).
  • 🔔 Check notifications (Settings → Notifications).
  • 🔒 Enable two-step verification (Account → Two-step verification) for security.
💡

Resetting WhatsApp data does not delete media files from the folder WhatsApp/Mediabut erases all settings, chat history (if there is no backup) and call data.

6. Optimizing WhatsApp: how to prevent memory clogging

To WhatsApp not take up gigabytes of memory every few months, configure it correctly:

  • 📁 Disable auto-downloading media: 
    Settings → Storage and data → Autoload media

    Select "Never" or "Wi-Fi only" for mobile data.

  • 🗃️ Limit backup size: 
    Settings → Chat → Chat backup → Enable video

    Disable video backups - they take up the most space.

  • 🧹 Regularly clean up old files:

    Use built-in storage manager (Settings → Storage and data → Storage management) once every 1-2 months.

  • 🔄 Update WhatsApp:

    In new versions, work with memory is optimized (updates are coming via Google Play).

If you often receive large files (for example, videos or archives), save them directly to the cloud (Google Drive, Dropbox) or to your computer, and not to your phone memory.

7. Problems after cleaning: what to do if WhatsApp does not work

Sometimes after deleting files or resetting data WhatsApp may behave incorrectly: not sending messages, not showing media, or constantly restarting. Here's how to fix it:

Problem Possible reason Solution
Messages are not sent Synchronization failed Check your Internet connection and restart the application
No photos in chats Deleted media files from folders WhatsApp/Media Ask to resend the files or restore from a backup
The application crashes Data is damaged after reset Reinstall WhatsApp and restore chats from the copy
The backup cannot be restored There is not enough space on the phone or Google Drive has crashed Free up 2-3 GB of memory and check the connection to your Google account

If the problem is not solved, try:

  1. Delete and restart install WhatsApp (chat data will be restored from a backup).
  2. Check whether an antivirus or optimizer is blocking the operation of the messenger (for example, Clean Master).
  3. Update Android to the latest version - older firmware may have bugs with operation applications.
⚠️ Attention: If, after cleaning, WhatsApp asks to confirm the number, but the SMS does not arrive, check whether your operator blocks service messages (for example, MegaFon or Beeline sometimes restrict them. Try requesting a code through). call.
