Your POCO X7 Pro stores temporary files and cached data that builds up over time. When storage gets low or apps start acting sluggish, clearing the cache can free up space and fix performance issues. Here's how to clean things up on your device running HyperOS 2.
Clear App Cache Individually
Go to Settings > Apps and tap on "Manage apps." Find and select the app you want to clean. Tap on Storage usage and then hit the Clear cache button. This removes temporary files without deleting your login or personal data within the app.
Focus on apps that use the most storage, like browsers, social media, and games. These tend to accumulate the largest caches over time. I'd start with those if you're noticing general slowdowns.
Clear Cache for All Apps at Once
Your POCO X7 Pro has a handy built-in cleaner. Open the Security app on your home screen. Tap on Cleaner and let it scan. It will show you junk files, which include cached data from all your apps. You can then tap to clear it all with one button.
This is much faster than going app-by-app and is a great weekly maintenance habit. It helps keep the system responsive, which can sometimes help with the occasional notification delays some users report in HyperOS 2.
Clear Your Browser Cache
If you use Chrome, open the app and tap the three-dot menu in the top right. Go to History > Clear browsing data. Under the "Basic" tab, make sure Cached images and files is selected. Choose your time range and tap Clear data.
This won't log you out of websites unless you also clear cookies and site data. It's a good fix if web pages are loading slowly or incorrectly.
Wipe the System Cache Partition
This clears system-level cached data, which can fix lag or odd glitches, especially after a software update. First, power off your phone completely. Press and hold the Power and Volume Up buttons together until the POCO logo appears, then release.
Use the Volume buttons to navigate to "Wipe data" and press the Power button to select. On the next screen, choose Wipe cache and confirm. This process is safe and doesn't touch your personal photos, messages, or apps.
Use the Built-in Files Manager
Your POCO X7 Pro comes with a capable file manager. Open the Files app and look for categories like "Junk files" or "Clean" on the main screen. Tapping here will let you review and delete cached data and other temporary files quickly.
For a more powerful option, you can install Files by Google from the Play Store. Its "Clean" feature is excellent at identifying redundant files and large, forgotten downloads.
Manage Messages and Downloads
Old message threads, especially ones full of photos and videos, can take up a surprising amount of space. Go through your messaging app and delete old conversations you don't need. Also, regularly check your Downloads folder in the Files app.
Deleting install files for apps you've already installed or old documents you've saved can reclaim gigabytes. With a 6000mAh battery, the phone is built for endurance, but keeping storage free helps overall system health.
Restart Your Phone Regularly
A simple restart clears temporary system caches and frees up RAM. Just hold the Power button until the menu appears, then tap Restart. I recommend doing this once a week.
It's a quick trick that can resolve minor software hiccups and keep everything running smoothly. If you ever need to force a restart, just press and hold the Power button for about 15 seconds until the phone reboots.
Check Detailed Storage Usage
Go to Settings > About phone > Storage. Here, you'll see a detailed breakdown of what's using your space. Tap on categories like "Apps," "Images," and "Videos" to see the largest files and apps.
This is the best way to identify storage hogs. You can then decide to delete large files, offload photos to Google Photos, or clear the cache for specific apps that are taking up too much room.
