How to clear all cached data on Android device?

Is there a way to clear the cached data for all apps at once on an Android device? I know that I could use an app like Clean Master, but I have limited storage on my phone and I don’t want to take up space with an app when I need to save space. Is there a way to do a batch cache cleaning so I don’t have to go through and delete the cache for each individual app?

Here's how it's done:

Turn off phone
Remove the battery and reinsert.
Hold down the Home and Volume Up keys
Press and hold the Power button while still holding the other keys.
As soon as you see the Samsung logo, release all keys/buttons.
Press on the Volume Down to scroll down to Wipe Cache Partition.
Press the Power button to select it.
Press the Volume down button to highlight "Yes" and press the Power Button to select it.
Wait for a few minutes for the phone to clear the data.
Then press the Power button to select reboot system now.
Wait for your phone to reboot.

Your system cache should be wipe and leave you with a much more fluid smartphone.

Yes, at least on 4.4. I don’t have anything handy running an older version of Android so I can’t confirm that it will work on older versions, but you just need to go into your Settings, then scroll down to Device Storage (or Device>Storage depending on the phone/tablet). In Storage, scroll down the list of things taking up space until you see “Cached data.” Tap on “Cached data” and a popup offering to “Clear cached data” should appear. You can safely select OK to clear the cache for all apps at once.
