What is WhatsApp Cleanup and Why You Need It
By cleaning WhatsApp, you mean removing unnecessary or temporary data that the messenger accumulates during operation, which not only frees up space on Xiaomi’s internal drive, but can also speed up the application. However, many users mistakenly believe that cleaning is just deleting the cache – in fact, the process is much more complicated.
Here are the types of data that are to be cleaned:
- 📁 Messenger cache – temporary files that speed up media loading, but over time take up gigabytes of memory.
- 📸 Media files – photos, videos and voice messages automatically saved in the gallery.
- 🗑️ Logs and dumps are the service information WhatsApp creates for debugging (often left behind after crashes).
- 🔄 Outdated backups – old backups that are stored in device memory or Google Drive.

On Xiaomi smartphones, the situation is complicated by the fact that the firmware MIUI If you don’t clean WhatsApp regularly, the messenger can start to shut down, lose notifications or even stop syncing messages, especially for models with a small amount of memory (32 GB or 64 GB).

What data takes up the most space on WhatsApp on Xiaomi
To effectively clean WhatsApp, you need to understand which files are eating away memory. On Xiaomi smartphones, the main “eaters” of space:
- Video files — even short, high-resolution videos can weigh between 50 and 200 MB each, and when you actively share video in chat rooms, memory is filled in a matter of days.
- Voice messages – unlike text, they are stored as audio files and can accumulate for years.
- Cache thumbnails — WhatsApp creates smaller copies of all media for quick download in chat rooms. On Xiaomi, this cache is often duplicated in a folder MIUI/thumb.
- Backups – Local Backups (/sdcard/WhatsApp/Databases) weigh 1–3 GB each and stored in Google Drive for years.
- Error Logs – When WhatsApp crashes, it creates.log files in a folder. WhatsApp/CrashLogs, which are rarely removed automatically.
For clarity, we compare the “weight” of different types of data in WhatsApp (on the example of the average user):
| Type of data | Average size | Can I remove it without loss? |
|---|---|---|
| Text communications (yearly) | 5-10 MB | ❌ (chuckle down chat history) |
| Photos (1,000 units) | 1-2 GB | ✅ (if preserved in the gallery) |
| Video (50 pcs) | 2–5 GB | ✅ |
| Cash miniature | 200-500 MB | ✅ (regenerate automatically) |
| Local backups (3 units) | 3-9 GB | ✅ (except for) |
On Xiaomi smartphones with firmware MIUI 12 WhatsApp cache can be duplicated in the system folder /MIUI/optimize, This is due to the Deep Optimization feature, which creates copies of commonly used files.
