1 What data files are created by WhatsApp on Xiaomi and why they are needed
WhatsApp on Xiaomi (as well as other Android devices) stores data in two main locations:
- Application folder (/storage/emulated/0/WhatsApp/) – here are media files, backups and service data.
- Android internal storage (/data/data/com.whatsapp/) – this store stores the cache, settings and current message base.
Let’s take a look at each type of file in detail:
| File type | Extension/name | Where it's stored | Can I remove it? |
|---|---|---|---|
| Communications database | msgstore.db.crypt14 | /WhatsApp/Databases/ | ❌ No (will result in loss of chats) |
| Backup copies | msgstore-YYYY-MM-DD.1.db.crypt14 | /WhatsApp/Databases/ | ⚠️ Partially (you can remove old ones) |
| Media files | .jpg,.mp4,.opus, etc. | /WhatsApp/Media/ | ✅ Yes (but check your auto-save settings) |
| Cash app. | Folder cache | /data/data/com.whatsapp/cache/ | ✅ Yes (cleansed without consequences) |
| .nomedia files | .nomedia | In all WhatsApp folders | ❌ No (hiding gallery media) |
Xiaomi Feature: Due to Optimizations MIUI WhatsApp files can be duplicated in the folder MIUI/Extra or MIUI/Backup. This is not a mistake – the system reserves data for quick recovery after reset.
2.Why WhatsApp is taking up so much space on Xiaomi
On Redmi Note 10 Pro, POCO X3 or Mi 11 smartphones, WhatsApp can eat up 5-15GB of storage - even if you don't manually save media.
- 📸 Automatic Media Saving: WhatsApp downloads all photos and videos from chat rooms to folder by default /WhatsApp/Media/. Nana MIUI This is compounded by the fact that the system can create miniatures for the gallery.
- 🗄️ Local backups: WhatsApp backs up the messaging database every night. Old copies are not automatically deleted.
- 🔄 Duplication of files: due to the features MIUI Media files can be stored in the WhatsApp folder and in the DCIM/.thumbnails.
- 🎵 Voice Messages:.opus files take up little space, but if you listen to audio in chats often, they accumulate.
For example, on the Xiaomi Mi 10T with 128 GB of memory, the user may not notice how WhatsApp will take 8-10 GB in six months of active use – especially if it consists of several group chats with media exchange.

3.What happens if you delete WhatsApp files: the consequences for each type
Not all WhatsApp files can be deleted without risk, but this is what happens when you clean up different types of data.
