Cache is a temporary file that creates apps and a system to speed up its work, for example, when you open Instagram, it stores thumbnails of photos in cache so that the next time it runs, it shows them instantly, the same thing happens with the browser, messengers and even system processes.

On the Redmi. 8A With its modest characteristics, cache plays a dual role:

• ✅ Plus: Accelerates re-runs of applications (especially important for a weak processor)
• ❌ Minus: It takes up 30% from available memory (only 32 GB version. ~8-10 GB!)
• ⚠️ Risk: Fragmented cache slows down the system more than its absence

When cache becomes a problem:

• 📱 The phone hangs when switching between applications
• 🔄 Applications are closed spontaneously (especially games)
• 📉 Free memory is less than 1 GB at 32 GB
• 🔋 The battery goes down quickly (the system spends resources on managing clogged cache)
