If your Xiaomi 15T has started feeling sluggish, an app keeps crashing, websites aren’t loading properly, or you’re running low on storage, clearing cached files can sometimes help.

Cache isn’t necessarily a bad thing. Android apps deliberately keep temporary files so they can open faster and remember certain pieces of information. The problem is that these files can occasionally become outdated, corrupted, or unnecessarily large.

The good news is that you don’t need a special cleaner app to deal with them. Your Xiaomi 15T already includes several useful tools for managing temporary data.

In this guide, I’ll walk you through five practical ways to clear cache on Xiaomi 15T, starting with the safest and easiest option.

What Does Clearing Cache Actually Do?

Before you start deleting anything, it’s worth understanding what you’re removing.

An app’s cache contains temporary files that help it work more quickly. For example, a social media app might temporarily store images you’ve already viewed instead of downloading them again.

Clearing the cache removes those temporary files, but it normally does not delete your personal files, photos, messages, accounts, or app documents.

The app can simply create fresh cache files when you use it again.

Important: Don’t confuse Clear cache with Clear data. Clear data is much more drastic and can reset an app, remove locally stored information, or sign you out.

Method 1: Clear Cache for an Individual App

This is usually the best place to start if one particular app is giving you trouble.

For example, if your browser keeps freezing or a messaging app isn’t loading correctly, clearing that app’s cache may solve the problem without affecting your other apps.

Follow these steps:

1. Open Settings on your Xiaomi 15T.
2. Tap Apps.
3. Find and select the app that’s causing problems.
4. Tap Storage.
5. Select Clear cache.
6. Return to the app and try using it again.

That’s it.

You may notice that the first time you open the app afterward, it takes slightly longer to load. That’s normal because the app has to rebuild some of its temporary files.

When should you use this method?

Try clearing an individual app’s cache when:

• The app keeps crashing.
• The app freezes or becomes unresponsive.
• Images or pages aren’t loading correctly.
• An app is behaving strangely after an update.
• One particular app is consuming an unusually large amount of temporary storage.

There’s generally no reason to clear every app’s cache just because you can. Start with the app that’s actually causing the problem.

Method 2: Clear Your Browser Cache

If the problem is happening while browsing the web, clearing the browser’s cached files can be more useful than clearing the cache of unrelated apps.

You can do this from whichever browser you normally use.

Google Chrome

The exact menu wording can vary slightly between versions, but the general process is:

1. Open Chrome.
2. Tap the three-dot menu.
3. Select Delete browsing data.
4. Choose a Time range.
5. Select Cached images and files.
6. Tap Delete data.

If you only want to remove temporary cached files, be careful about selecting options such as saved passwords or browsing history unless you actually want those removed.

Samsung Internet

For Samsung Internet:

1. Open Samsung Internet.
2. Tap the menu button.
3. Open Settings.
4. Find Browsing data or the privacy-related settings.
5. Select the option for deleting browsing data.
6. Choose cached files.
7. Confirm the deletion.

Browser cache can be worth clearing when a website displays an old version of a page, images refuse to load, or a website behaves differently than expected.

Method 3: Use Device Care to Free Up Space

Samsung phones include built-in storage and maintenance tools that can help you identify unnecessary files.

Depending on your software version, the menu names can differ slightly.

Try this:

1. Open Settings.
2. Tap Device care.
3. Select Storage.
4. Review the categories shown on the screen.
5. Remove files you no longer need.

On some versions, you’ll see a Clean now or similar optimization option.

Keep in mind that Device Care isn’t simply a giant “delete all cache” button. It evaluates storage and temporary files and provides tools for freeing space.

Why use Device Care?

It’s particularly useful if you’re trying to figure out what is actually consuming your storage rather than blindly deleting cached data.

Before removing anything, check what the system is recommending so you don’t accidentally delete something you wanted to keep.

Method 4: Wipe the Cache Partition

This is the more advanced option.

The cache partition is different from an individual app’s cache. Wiping it can be useful after certain system updates or when you’re experiencing persistent software-related problems.

Most importantly, wiping the cache partition is not the same as performing a factory reset.

However, the Recovery Mode menus and connection requirements can vary depending on the Android/One UI version installed on your device.

General process

1. Turn off your Xiaomi 15T.
2. Connect it to a computer with a USB cable if your software version requires a USB connection for Recovery Mode.
3. Enter Recovery Mode using the appropriate hardware-button combination for your device/software version.
4. Use the volume buttons to navigate through the Recovery menu.
5. Select Wipe cache partition if the option is available.
6. Confirm the operation.
7. Select Reboot system now.

A very important warning

Do not select “Wipe data/factory reset” unless you intentionally want to erase the device.

That option is completely different from wiping the cache partition and can remove your personal data.

If Wipe cache partition isn’t shown, don’t assume something is wrong. Recovery options can change between software releases and device variants.

Method 5: Restart Your Xiaomi 15T

This sounds almost too simple, but don’t overlook it.

A restart can clear temporary system processes and give Android a fresh start. If you’ve already cleared an app’s cache, restarting the phone is a sensible next step.

To restart:

1. Press and hold the Side button and Volume Down button.
2. Wait for the power menu to appear.
3. Tap Restart.
4. Confirm if necessary.
5. Wait for the phone to boot completely.

After restarting, open the app or feature that was giving you trouble.

Sometimes the issue disappears without needing any deeper maintenance.

Clear Cache vs. Clear Data: What’s the Difference?

This is one of the most important things to understand before troubleshooting an Android app.

If you’re simply trying to fix an app that’s acting strangely, try Clear cache first.

Don’t jump straight to Clear data unless you understand what the app stores locally and are prepared to set it up again.

Does Clearing Cache Make Xiaomi 15T Faster?

Sometimes, but don’t expect a dramatic speed boost every time.

Cache exists for a reason, so deleting it isn’t a magical performance upgrade. Android and individual apps will simply rebuild temporary files as they’re needed.

Clearing cache is most useful when you’re troubleshooting a specific problem, such as:

• An app repeatedly crashing
• A website displaying outdated information
• An app behaving strangely after an update
• Temporary files taking up unnecessary space
• A feature that suddenly stops working correctly

If your phone is slow all the time, clearing cache may not be enough. You may need to investigate storage space, background apps, software updates, battery-related performance settings, or a problematic application.

How Often Should You Clear Cache?

There’s no need to clear your cache every day or every week.

In fact, regularly deleting all cached files can be counterproductive because apps will simply recreate them.

A better approach is to clear cache when there’s a reason to do it.

For example, if an app starts malfunctioning after an update, clearing its cache is a reasonable troubleshooting step.

What If Clearing Cache Doesn’t Fix the Problem?

Don’t keep clearing cache repeatedly if the same problem continues.

Try these troubleshooting steps instead:

1. Restart the phone

A simple reboot can resolve temporary software glitches.

2. Update the problematic app

Open the Google Play Store and check whether a newer version is available.

3. Check for system updates

Go to:

Settings → Software update → Download and install

If an update is available, install it when convenient.

4. Check available storage

If your phone is nearly full, deleting unnecessary downloads, videos and other large files can be more useful than repeatedly clearing cache.

5. Clear the app’s data

If the app is still broken, Clear data may be the next troubleshooting step—but remember that this can reset the application.

6. Reinstall the app

If nothing else works, uninstalling and reinstalling the problematic app can provide a cleaner reset.

Frequently Asked Questions

Does clearing cache delete photos?

No. Clearing an individual app’s cache doesn’t normally delete photos stored in your Gallery or personal files.

Does clearing cache log me out?

Normally, Clear cache doesn’t log you out. However, Clear data can reset the app and may require you to sign in again.

Is it safe to clear app cache?

Yes, clearing an app’s cache is generally a safe troubleshooting step.

Should I use a cache-cleaning app?

Usually, you don’t need one. Your Xiaomi 15T already provides built-in tools for managing apps and storage.

Why does cache come back after I delete it?

That’s completely normal. Apps create temporary cached files again as you use them.

Does clearing cache delete app settings?

No, not normally. That’s one of the main differences between Clear cache and Clear data.

Final Thoughts

Clearing cached files can be a useful troubleshooting trick, but it shouldn’t be treated as something you have to do constantly.

If one app is misbehaving, clear that app’s cache first. If you’re dealing with browser problems, clear the browser cache. If you’re trying to understand what’s consuming storage, use the phone’s built-in storage tools.

And if the problem started after a system update or continues despite clearing individual app caches, the cache may not be the real culprit.

Start with the simplest method, make changes one at a time, and you’ll have a much better chance of figuring out what’s actually wrong with your Xiaomi 15T.
