How to remove all cache from your phone Xiaomi 5 working ways

Cache on Xiaomi smartphones are temporary files that speed up applications, but over time take up gigabytes of memory and slow down the system. If your Redmi, POCO or Mi started to slow down, spontaneously reboot or give out errors "Not enough memory", the problem most often lies in the cache clogged. However, just clearing it through the standard menu is not enough - you need to delete all types of cache: system, app cache and even hidden Dalvik files.

In this article, you will find 5 proven ways to completely clean up the cache on Xiaomi, including methods through Recovery, ADB and third-party utilities. We will also analyze which files can be deleted without risk to the system and which should not be touched. The instructions are valid for all models on MIUI 12-14 (including Redmi Note 12, POCO X5, Mi 11, etc.) and do not require root rights.

Why Xiaomi Cache Should Be Cleaned Regularly

Cache is not just junk, it's a necessary element for a smartphone to run fast, but it's a big problem with too much of it.

• 📉 Slowing down the system: MIUI Starts to hang when opening applications or switching between them.
• 🔋 Increased battery consumption: background processes are constantly reassembling the cache, draining the battery.
• 🚨 App errors: For example, Google Play displays “Error 924” or games crash on download.
• 📱 Memory Lack: Even with 128 GB of internal memory, the system shows "Memory is full".

This is especially critical for Xiaomi budget models (for example, Redmi 9A or POCO M3), where the memory capacity is limited to 32-64 GB. In such cases, the cache can take up to 10-15 GB - almost a quarter of the total!

⚠️ Warning: Do not confuse cache with user data. Clearing the cache will not delete your photos, messages or saves in games, but will reset the settings of some applications (for example, you will have to re-enter your login to Instagram or Tinkoff Bank).
