An app is misbehaving, a website keeps showing last week’s version of itself, or your storage graph has a suspicious “Cached data” chunk. Clearing the cache fixes the first two — and it’s safe, because cache is just temporary files apps keep so they open faster; clearing it deletes nothing you’ve made: no photos, messages, logins or settings. The part most guides get wrong is the scope: on modern Android there is no longer one “clear all cache” button, so you clear it per app, inside Chrome, or through your phone brand’s storage tool.
Quick answer: for a single app open Settings > Apps > [the app] > Storage & cache > Clear cache. For Chrome, tap the three-dot menu > Settings > Privacy and security > Delete browsing data, tick Cached images and files and delete. Never tap Clear storage unless you mean to reset the app entirely — that one erases logins and settings. Here’s the full map, including Samsung and Pixel paths and what not to bother with.
Cache vs. data: the difference that matters
Every Android app has two storage buttons, and they are not interchangeable. Knowing which is which is the whole skill.
| Button | What it deletes | What survives | Use it when |
|---|---|---|---|
| Clear cache | Temporary files: thumbnails, streamed media, web snippets | Logins, settings, chats, progress, everything you made | App glitches, stale content, mild space pressure |
| Clear storage (a.k.a. Clear data) | Everything: the app resets to first-install state | Only cloud-synced data comes back after you log in | You’re deliberately resetting an app |
Clearing cache is therefore the safe first move in almost every case. Worst case, the app re-downloads what it needs and the space comes back — which is also why cache clearing is a temporary storage fix, not a permanent one.
Clear one app’s cache
- Open Settings > Apps (on some phones Applications or Apps & notifications).
- Tap See all apps if the list is collapsed, then choose the app.
- Tap Storage & cache.
- Tap Clear cache. The number next to “Cache” drops to zero (or near it).
Two honest notes: the cache figure often rebuilds within minutes for apps like Spotify or YouTube — that’s by design, not a bug. And for some system apps (Settings itself, Phone, carrier apps) the button may be greyed out; those caches are protected because clearing them can break core functions. That’s Android working as intended, not a problem to solve.
Hunting several heavy apps at once? On most phones the Apps list has a filter or sort option (often under a three-dot menu) — sort by Size to walk down the biggest apps first. On Samsung Galaxy phones the same list lives at Settings > Apps with the sort control in the menu, and each app’s storage page reads the same way.
Clear Chrome’s cache
Browsers are the biggest cache builders on most phones, and Chrome manages its own separately from the app list. This matches Google’s own clearing instructions:
- Open Chrome and tap the three-dot menu at the top right.
- Tap Settings > Privacy and security > Delete browsing data.
- Untick Browsing history and Cookies and site logins unless you want those gone too — leaving only Cached images and files ticked keeps you signed in everywhere.
- Pick a time range (use All time for a genuine clear) and tap Delete data.
Clearing cookies instead of cache is what logs you out of sites — that’s why the untick step above matters if your only goal is a cache clean.
The “clear all cache” button that no longer exists
Older guides walk you to Settings > Storage > Cached data and a single tap that purged every app’s cache at once. Google removed that shortcut from stock Android years ago, and most brands followed — so if your phone doesn’t show it, nothing is broken. The modern equivalents:
- Stock Android (Pixel and most non-Samsung phones): Settings > Storage > Free up space (it may open the Files by Google app), which suggests cached files and downloads worth removing individually.
- Samsung Galaxy: Settings > Battery and device care > Storage, then Clean now — Samsung’s one-tap routine clears caches and leftover files it considers safe. On older One UI versions the path starts at Device care.
- Recovery-mode “wipe cache partition”: a classic from older guides that’s obsolete — most phones made in the last several years simply don’t have a cache partition anymore, so there’s nothing to wipe.
When clearing the cache actually helps — and when it doesn’t
Cache clearing is a scalpel, not routine maintenance. It’s genuinely useful for:
- A single app acting up — crashing on open, showing wrong content, refusing to refresh. Clear that app’s cache; if it’s still broken, clearing storage (after checking the app backs up to the cloud) is the next step. When the misbehaving app is your browser or anything network-dependent, also rule out the connection itself — our Android Wi-Fi connected but no internet guide covers that failure shape.
- Stale web content — a site that keeps serving an old page after you know it changed. Chrome’s cache clear fixes it.
- Updates gone sideways — right after an app update misbehaves, cache clearing clears out the old-version debris.
It’s not a performance routine: Android manages cache automatically, evicting old files the moment an app needs room, so a “full” cache isn’t slowing your phone down. And it’s not a real storage solution — cache is usually a few hundred megabytes on a full phone that’s drowning in 4K videos. For actual space recovery, delete duplicates and old downloads; our guides to finding duplicate videos and photos on Android and fixing a slow, freezing Android phone cover the bigger levers (and iPhone users have the same playbook in freeing iPhone storage without losing photos).
One warning that saves people real harm: skip the “cleaner”, “booster” and “speed up your phone” apps in the Play Store. The built-in tools above do everything they do — the third-party versions mostly add ads, notifications, and sometimes worse, while Android’s own storage management already runs in the background. Google’s free-up-space guide relies entirely on built-in tools, and so should you.
FAQ
Does clearing the cache delete photos or messages?
No. Cache is only re-downloadable temporary files. Your photos, texts, app accounts and settings are untouched. The only button that deletes real data is Clear storage, which resets the app you use it on.
Will I get logged out if I clear the cache?
No — logins survive cache clears in apps. In Chrome, only unticked properly: if you leave Cookies and site logins ticked in the delete dialog, you will be signed out of websites.
How often should I clear the cache on Android?
Only when something’s wrong — an app misbehaving or content stuck. There’s no maintenance schedule to keep; Android recycles cached files on its own, and constantly clearing them just makes apps slower while they rebuild.
Why is “Clear cache” greyed out for some apps?
System-critical apps (Settings, Phone, carrier services) protect their caches because clearing them can break calling or notifications. There’s no workaround and no need for one — the greyed-out state is deliberate.
Does clearing cache improve battery life?
Not meaningfully. Cache makes apps faster and often more battery-efficient, since re-downloading data costs more power than reading it locally. Clear it to fix a specific problem, not to gain runtime.
