How to Clean Up Viber Memory on Android Xiaomi: The Complete 2026 Guide

Viber is one of the most popular messengers, but over time it turns into a real memory eater on your Xiaomi. Photos, videos, stickers, voice messages and cache accumulate in gigabytes, slowing down both the application and the entire smartphone. The problem is particularly acute in the budget models of Redmi and POCO limited-volume (32/64 GB).

1.Why does Viber take up so much memory on Xiaomi?

Viber stores four types of data on the device, which grow over time:

• 🎬 Media files - photos, videos, GIFs, stickers from chats (the main "culprit" of memory overflows).
• 💬 Chat database – message history, contacts, settings (cannot be completely deleted without data loss).
• 🔄 Update files – residues after Viber updates (sometimes not automatically cleared).

At Xiaomi, the problem is aggravated by features MIUI:

• 🔋 Optimizing Memory in the Background May Interrupt Cache Cleanup.
• 📂 System restrictions on access to folders /Android/data/ rootless.
