How to Check Firestick Storage & Clear Cache (2026 Guide)
Learn how to check storage on Firestick and clear cache to fix buffering, app crashes, and slow performance. Step-by-step guide with screenshots.
Your Firestick is acting up again — apps crash mid-stream, everything feels sluggish, and you’re pretty sure it’s not your internet. I’ve been there more times than I can count. After years of troubleshooting these devices, I can tell you that 90% of the time, the culprit is simple: your storage is full or your cache is bloated.
Here’s the thing — your Firestick only has about 5-8GB of usable storage (depending on the model). Once you install a few streaming apps, add some Kodi builds, and let apps cache data over months, you’re running on fumes. The fix? Check your storage and clear that cache.
To check storage: go to Settings → My Fire TV → About → hover on Storage. To clear cache: Settings → Applications → Manage Installed Applications → select an app → Clear cache. This takes about 2 minutes and can fix buffering and crash issues immediately.
What I Tested For
I spent a weekend on my Firestick 4K Max — the one connected to my living room TV — running storage tests across three scenarios:
- Fresh device baseline — checking storage on a newly reset Firestick to see what Amazon’s OS actually uses
- Heavily-used device — my daily driver with 15+ apps, Kodi with several builds, and months of cached data
- Cache clearing impact — measuring how much space cleared and whether it actually fixed performance issues
The goal? Give you a repeatable process that works regardless of how technical you are.
How to Check Storage on Firestick
Checking your storage takes about 30 seconds once you know where to look. Here’s the exact path:
Check Firestick Storage
5 stepsOpen Settings
From your Firestick home screen, navigate to the top menu and select the Settings icon (the gear icon in the top right corner).
Go to My Fire TV
Scroll down and select My Fire TV — it’s usually near the bottom of the Settings list.
Open About
Within My Fire TV, select About to access device information.
Select Storage
Scroll down and hover over (or click) Storage to view your storage breakdown.
Review the Details
You’ll see two numbers: Total Space (what your Firestick has) and Available (what’s left). The screen also shows how much space each app is using.
How to Clear Cache on Firestick
Now that you know your storage situation, let’s clean up that cache. Clearing cache is safe — it removes temporary files but keeps your login credentials and app settings intact.
Clear Cache on Firestick
5 stepsOpen Settings
Navigate back to the home screen and select Settings from the top menu.
Go to Applications
Scroll down and select Applications from the Settings menu.
Manage Installed Applications
Select Manage Installed Applications to see a list of every app on your Firestick.
Select Your Target App
Choose the app you want to clear cache for. I recommend starting with your most-used streaming apps — Netflix, Kodi, Stremio, or whichever app is showing the highest storage usage.
Clear Cache
Select Clear cache (not Clear data — more on that difference below). Repeat this for other apps as needed.
What Actually Happens When You Clear Cache
After testing this on my heavily-used Firestick, here’s what I found:
| Action | Space Recovered | Effect on App |
|---|---|---|
| Clear cache (one app) | 10-200 MB | None — app works normally |
| Clear cache (all apps) | 500MB - 1.5GB | Faster loading times |
| Clear data | Varies | App resets — logins lost |
I cleared cache on my top 5 storage-hogging apps and recovered about 800MB — not bad for a 2-minute process. The real difference was in performance: apps loaded faster, and I didn’t get that annoying “Firestick is thinking” pause when switching between apps.
7 Ways to Free Up Space on Firestick
Beyond cache clearing, here are other methods I use to keep my Firestick running lean:
1. Uninstall Unused Apps
Go to Settings → Applications → Manage Installed Applications → select an app → Uninstall. Be honest — when was the last time you opened that app you downloaded for one specific show?
2. Delete APK Files
If you’ve sideloaded apps using 
Downloader, those APK files might still be sitting in your storage. Use a file manager like ES File Explorer to browse and delete leftover APKs.
3. Check Streaming App Downloads
Apps like Netflix and Amazon Prime Video let you download shows for offline viewing. Those downloads eat storage. Open each app, go to Downloads, and delete what you’ve already watched.
4. Remove Kodi Builds and Addons
Kodi builds can be storage monsters. If you’re running a heavy build, try reverting to a lighter setup or clearing Kodi’s cache separately through the build’s built-in maintenance tools.
5. Clear System Cache
Amazon doesn’t make this obvious, but you can clear the entire system cache. Go to Settings → My Fire TV → About → press and hold the Select button on your remote for about 10 seconds until you see a hidden menu. Select Clear cache from the menu.
6. Factory Reset (Last Resort)
If nothing else works and your Firestick is still crawling, a factory reset wipes everything and gives you a fresh start. Go to Settings → My Fire TV → Reset to Factory Defaults.
7. Use External Storage
If you have a Firestick 4K Max or Cube, you can connect external storage via USB. Go to Settings → My Fire TV → Other settings → External storage to format and use a USB drive for app storage.
When Storage Problems Cause Real Issues
I’ve seen storage-full Firesticks exhibit some pretty frustrating symptoms:
- App crashes — Apps don’t have enough room to load data properly and close unexpectedly
- Buffering — Even with good internet, a full Firestick can’t process streams efficiently
- Slow navigation — The home screen takes forever to load, menus lag
- Update failures — Your Firestick can’t download system updates without storage space
The fix is almost always the same: clear cache, uninstall unused apps, and if needed, do a factory reset. I’ve personally rescued three Firesticks from friends this exact way — all they needed was some spring cleaning.

The Bottom Line
Checking your Firestick storage and clearing cache is the single most effective maintenance task you can do for your streaming device. It takes 2 minutes, costs nothing, and can extend the life of your Firestick by months or even years.
If you sideload apps on your Firestick — whether it’s Kodi, Stremio, or Cinema HD — you need to be even more vigilant about storage management. Those apps cache more data than official Amazon Appstore apps, and without regular maintenance, they’ll slow your device to a crawl.
