1. Diagnosis: What exactly is taking up memory on the Redmi 8?

Before you clean up everything, you need to figure out which files are eating up space. Redmi 8 has a built-in memory analyzer, but it hides some of the system data.

Go to Settings → About Phone → Memory. Here you will see a diagram of the distribution of space by category: Apps, Images, Video, Audio and Other. Click on each category to see the details:

• 📱 Apps: sorted by size (look for games and social media – they often weigh in on the size of the app) 1-3 GB).
• 📷 Images: not only gallery photos, but also screenshots are taken into account here (DCIM/Screenshots), downloaded images from messengers (Pictures/Telegram or WhatsApp/Media).
