If your Amazon Fire TV Stick has started freezing, returning to the home screen unexpectedly, or constantly buffering right in the middle of a live broadcast, you are probably running into a storage limit.
This is an incredibly common issue, especially if you use IPTV-tjenester. Because Fire Sticks only come with about 8GB of internal storage (and part of that is eaten up by the operating system), they get bogged down easily. Every time you open an app, it stores temporary files like image thumbnails, watch histories, and login tokens in a hidden folder called the cache.
For IPTV users, this problem is magnified. Your IPTV player is constantly downloading massive EPG (Electronic Program Guide) data files, thousands of channel logos, and video-on-demand cover art. If you don’t clear this out, your device will eventually crawl to a halt.
Here is exactly how to clear the cache and data on your Fire TV to get it running smoothly again.
The Fastest Way: Clearing All Cache at Once
If your Fire TV device is fully updated to the latest FireOS, Amazon recently added a highly requested feature that allows you to clear the cache for every app simultaneously.
Go to the Fire TV home screen and navigate to Indstillinger (the gear icon on the far right).
Vælg Anvendelser.
Look for the option labeled Clear All Application Caches.
Select it, and the screen will tell you exactly how much space you are about to free up.
Trykke Confirm.
Note: If you don’t see this option, your Fire TV is likely running an older software version. You can still clear your cache using the manual method below.
The Manual Method: Clearing Cache for Specific Apps
If you only want to target specific heavy apps (like your IPTV player, Kodi, or a streaming app that is acting glitchy), you can do it manually.
Gå til Indstillinger (the gear icon).
Scroll down and select Anvendelser.
Choose Manage Installed Applications.
Scroll through your list of apps and select the one causing issues.
Klik Ryd cache.
You will notice the “Cache” size on the right side of the screen drop to 0 KB. You can repeat this process for any other apps that are hogging space.
Clear Cache vs. Clear Data: What’s the Difference?
When you click on an app in the settings menu, you will see two distinct options. It is crucial to understand the difference, especially for IPTV-apps, so you don’t accidentally delete your account setup.
Clear Cache: This is the safe option. It deletes temporary, disposable files (like old EPG data, leftover update files, and image thumbnails). It will not delete your login details or settings. Your IPTV playlists, XTREAM codes, and favorites will remain perfectly intact.
Clear Data: This is the nuclear option. Clicking this acts like a factory reset for that specific app. It wipes everything. If you clear the data on your IPTV player, you will be logged out, your playlists will be deleted, and you will have to set up your portals or M3U links from scratch. Only use “Clear Data” if an app is completely broken and clearing the cache didn’t fix it.
3 More Ways to Stop Your Firestick from Buffering
If you cleared the cache and your IPTV streams are still buffering or stuttering, the issue might not be storage. Try these tweaks:
1. Disable the Screensaver
This is a lesser-known trick, but the Amazon screensaver actually downloads and caches high-resolution images constantly in the background. Disabling it can free up memory and stop background processing.
Gå til Settings > Display & Sounds > Screensaver.
Change the Start Time to Never.
2. Turn Off Background App Updates
When apps update automatically in the background while you are trying to stream a live match, your bandwidth and processor take a massive hit.
Gå til Settings > Applications > Appstore.
Toggle Automatic Updates to Off.
3. Force Stop Unused Apps
Just because you exited an app doesn’t mean it actually closed. Many apps run silently in the background, eating up your Fire TV’s limited RAM.
Gå til Indstillinger > Applikationer > Administrer installerede applikationer.
Click on apps you aren’t currently using and select Force Stop.
Pro-tip
Making a habit of clearing your Fire TV cache once a month will prevent 90% of the freezing and buffering issues you encounter. If you are a heavy IPTV user, doing this right before a major live sports event ensures your device has the maximum amount of memory available to process the stream without dropping frames.
