Is your phone slow, or is an app acting strange? Learning how to clear cache on Android is one of the quickest fixes. App cache is a store of temporary files that helps apps load faster. Over time, though, it can grow large, take up storage and even cause glitches. This guide shows you how to clear app cache safely, when to do it and what it really changes.

What is app cache?
When you open an app, it saves small files such as images, thumbnails and scripts. Next time, the app loads these files from your phone instead of downloading them again. That is the cache.
Cache is useful most of the time. However, it can cause problems when:
- it grows to several gigabytes and fills your storage;
- old or damaged cache files make an app crash or freeze;
- an app shows outdated content after an update.
Cache vs data: know the difference
Before you clear anything, understand the two buttons you will see.
- Clear cache removes temporary files only. Your accounts, chats and settings stay safe.
- Clear storage or clear data resets the app completely. You may lose logins, downloads and offline files.
So start with clear cache. Use clear data only when nothing else works, and only if your important data is backed up.
How to clear cache on Android for one app
This method works on most phones, including Samsung, Tecno, Infinix, Xiaomi and Pixel:
- Open Settings.
- Tap Apps or Apps & notifications.
- Choose the app, for example Chrome or Instagram.
- Tap Storage or Storage & cache.
- Tap Clear cache.
The cache size drops to zero or close to it. Open the app again and it will rebuild only the files it needs.
Which apps use the most app cache?
Some apps build huge caches. Check these first:
- Social media: Instagram, TikTok, Facebook and X.
- Browsers: Chrome and other browsers store website files.
- Streaming apps: YouTube, Spotify and Netflix.
- Messaging apps: Telegram can store large media caches.
To find the biggest ones, go to Settings > Storage > Apps and sort by size where available.
Clear cache on Android in Chrome
Website cache inside Chrome is separate from the system app cache. To clear it:
- Open Chrome and tap the three dots.
- Tap Delete browsing data or Clear browsing data.
- Tick Cached images and files.
- Choose a time range, then tap Delete data.
Leave cookies and passwords unticked if you want to stay logged in to websites.
Can you clear all cache at once?
Older Android versions had a single “cached data” button. Newer versions removed it for most phones. Some brands include a cleaner tool instead, such as Device Care on Samsung or Phone Manager on Tecno and Infinix. These tools can remove junk files in one tap.
Avoid random “cleaner” apps from unknown developers. Many show heavy ads and some collect your data. The built-in tools are usually enough.
How often should you clear cache?
You do not need to clear cache every day. In fact, doing it too often makes apps slower, because they must download everything again. A good rule:
- clear cache when an app misbehaves;
- clear it when storage is almost full;
- check large apps once a month.
If storage is your main problem, read our full guide on how to free up storage on Android. For a slow phone, also see how to speed up a slow Android phone.
What happens after you clear app cache?
- The app may open a little slower the first time.
- Images and feeds may reload.
- Your login, chats and settings remain.
- You gain back storage space immediately.

Other quick fixes for a misbehaving app
Sometimes clearing the cache is not enough. If an app still crashes or freezes, try these steps in order. First, force stop the app from its settings page, then open it again. Next, check the Play Store for an update, because developers often fix bugs quickly. After that, restart your phone to clear memory and background processes.
If the problem continues, uninstall the app and install it again. This gives you a completely fresh copy. Before you do, make sure your chats, notes or files inside the app are backed up or synced to your account.
Finally, check that your phone itself is up to date. Go to Settings > System > Software update and install any available update. Old system software can cause apps to behave badly, especially after the apps themselves update. For Samsung users, our guide on updating Samsung phone software walks you through it.
Frequently asked questions
Is it safe to clear cache on Android?
Yes. Clearing cache only removes temporary files. Your accounts, photos and messages stay on the phone.
Will clearing cache delete WhatsApp chats?
No. Clearing WhatsApp cache does not delete chats. Clearing WhatsApp data or storage could, so always back up first.
Why does the cache come back?
Apps rebuild cache as you use them. That is normal and helps them run faster.
Now you know how to clear cache on Android safely. Use it as a quick fix for slow or buggy apps, keep an eye on your biggest apps, and your phone will stay faster for longer.
