Your Android phone felt fast when it was new. After months of browsing and streaming, apps now lag and storage keeps filling up.
Often the cause is cached data, not a broken phone. This guide shows how to clear it safely on Samsung and Pixel phones.
Quick Answer
Go to Settings > Apps, choose an app, then tap Storage or Storage & cache. Tap Clear cache only, never Clear storage.
Repeat for Chrome and your largest apps. This frees space without deleting photos, messages, or logins.
What Is Cached Data on Android?
Apps save small temporary files to load faster next time. Instagram saves viewed profile pictures, and Chrome saves images from sites you visit.
Maps, music, and video apps do the same thing. Google Maps saves map tiles, while Spotify saves parts of songs you played.
Cache helps in the short term. Your phone downloads less data and opens familiar content more quickly.
Over time, that cache grows very large. One social app can easily hold 500MB to 2GB after a few months of daily use.
Cached files can also become corrupted after updates. That is why an app may crash, freeze, or keep showing old content.
Clearing cache removes only those temporary files. The app rebuilds them fresh as you start using it again.
Cache vs. App Data: Know the Difference
Android shows two similar buttons in app storage settings. They look alike, but they do very different jobs.
What Clear Cache Does
Clear Cache deletes temporary files only. You stay signed in, and your settings and preferences stay exactly as they were.
The app may load slightly slower the first time afterwards. It needs to download fresh images and files again.
What Clear Storage Does
Clear Storage, sometimes called Clear Data, resets everything. It returns the app to its first-install state.
You will be signed out if you use it. Offline downloads are removed, and in-app settings are reset too.
Use Clear Storage only for a badly broken app. For routine cleaning, always choose Clear Cache instead.
How to Clear Cache for Individual Apps
Clearing apps one by one is the safest approach. You can target the biggest apps without affecting everything else.
Recent Android versions have no single clear-all button. Checking apps individually also shows you which ones use most space.
On Samsung Galaxy Phones (One UI)
- Open Settings and tap Apps.
- Find the app, using search at the top if needed.
- Tap the app name, then tap Storage.
- Tap Clear cache at the bottom right.
- Check that the cache figure drops to zero.
- Go back and repeat for the next app.
To find the heaviest apps first, use the sort option. In Settings > Apps, tap the sort icon and choose Size.
On Google Pixel and Stock Android
- Open Settings and tap Apps.
- Tap See all apps to open the full list.
- Tap the app you want to clean.
- Tap Storage & cache.
- Tap Clear cache, not Clear storage.
- Repeat for your other large apps.
Motorola and Nothing phones follow almost the same path. Older versions may call the first menu Apps & notifications instead.
Which Apps Should You Clear First?
Start with Chrome, Facebook, Instagram, and TikTok. YouTube, Spotify, and news apps also build cache very quickly.
These apps handle hundreds of images and videos daily. That is why their cache grows faster than most other apps.
WhatsApp can hold a large cache too. Clear it through Settings only, and do not delete files inside WhatsApp unchecked.

How to Clear Browser Cache in Chrome
Your browser stores cache from every website you visit. Clearing it fixes sites that load incorrectly or show old pages.
- Open Chrome and tap the three-dot menu.
- Tap History, then Clear browsing data.
- Choose All time at the top for a full clear.
- Tick Cached images and files.
- Leave Cookies unticked if you want to stay signed in.
- Tap Clear data and confirm.
Samsung Internet uses a slightly different path. Its privacy settings contain a similar delete browsing data option.
- Open Samsung Internet and tap the three-line menu.
- Tap Settings, then Privacy and security.
- Tap Delete browsing data.
- Select Cached images and files.
- Tap Delete data to finish.
Google explains each Chrome option in detail. Read the official guide to clearing cache and cookies in Chrome before changing cookie settings.
How to Clear the System Cache Partition
Android also keeps temporary system files after updates. Older phones stored these in a separate cache partition.
Modern Pixel phones do not offer this option. Many recent Samsung models still do, through Recovery Mode.
- Turn the phone off completely.
- Connect it to a computer by USB if required.
- Hold Volume Up and Power until the logo appears.
- Highlight Wipe cache partition using volume keys.
- Press Power, highlight Yes, and confirm.
- Select Reboot system now when it finishes.
This process does not touch personal files. Never select Wipe data or Factory reset in that menu, because that erases everything.
Only try Recovery Mode if you feel confident. Menu wording varies by model, Android version, and region.
How Often Should You Clear Cache?
You do not need to clear cache every day. Doing it too often makes apps slower, because they rebuild everything repeatedly.
Once every one to two months is sensible for most people. Clear sooner if an app crashes or storage is nearly full.
Samsung includes a useful built-in helper. Go to Settings > Battery and device care and tap Optimise now.
Pixel users can open Files by Google instead. The Clean tab suggests junk files and large caches that are safe to remove.
Treat those tools as a monthly habit. Combine them with manual clearing for the best result.
Common Mistakes and Safety Tips
The biggest mistake is tapping Clear Storage by accident. Always read the button label twice before you confirm anything.
Another mistake is installing random cleaner apps from pop-ups. Many show aggressive adverts and ask for permissions they do not need.
Android already has the tools you need built in. You do not need a third-party cleaner for this job.
Do not expect cache clearing to fix full storage alone. Check Settings > Storage to see whether photos and videos are the real problem.
Remember that cache always grows back afterwards. That is normal, healthy behaviour, not a fault with your phone.
Be extra careful with banking and work apps. Clearing cache is safe, but clearing storage may require verification again.
Conclusion
Clearing cache is safe, quick, and genuinely useful. Clear Cache removes temporary files, while Clear Storage resets an app completely.
Work through your largest apps in Settings > Apps first. Then give Chrome its own clear-out for the full benefit.
Repeat the routine every month or two, or when an app misbehaves. Skip shady cleaner apps and use built-in tools instead.
Done this way, your phone should feel faster and cleaner. You will free space without risking photos, messages, or accounts.
Frequently Asked Questions
Will clearing cache delete my photos or messages?
No, it only removes temporary files apps save for speed. Your photos, videos, messages, contacts, and accounts are not touched at all.
Why does the cache fill up again so quickly?
Apps rebuild cache as soon as you use them again. It only becomes a problem when it reaches several gigabytes or causes errors.
Is it safe to clear cache for every app?
Yes, for almost every app, including browsers and social media. The first load afterwards may be slightly slower than usual.
Why is there no button to clear all cache at once?
Google removed that option in newer Android versions. Clearing the largest apps individually gives similar benefits with much more control.
Should I use a cache cleaner app from the Play Store?
Usually not, because most duplicate what Android already does. Stick to Settings, Samsung Device Care, or Files by Google instead.
