How to Clear Cache on Firestick (and Speed It Up)
To clear the cache on a Firestick, open Settings, go to Applications, then Manage Installed Applications. Pick the app that is misbehaving and select Clear Cache. On newer Fire TV software there is also a Clear all Application Caches option on that same screen, which does every app in one go. Clearing the cache does not sign you out or delete anything you set up. Clearing data does, and that difference is the part most guides skip.
This guide covers both, when each one is worth doing, and what to try when the Firestick is still slow afterwards.
What the cache actually is
Every app on a Fire TV keeps a folder of temporary files: thumbnails, channel logos, bits of menus it has already loaded, and similar leftovers. The idea is speed. The next time you open the app, it reads those files instead of downloading them again.
Over months that folder grows, and sometimes a file in it gets corrupted. The app then starts acting strangely: it freezes on the splash screen, a menu shows old information, or the whole device crawls because storage is nearly full. Wiping the cache forces the app to rebuild those files fresh. Nothing important lives there, so you lose nothing except a slightly slower first launch.
How to clear the cache for one app
- Press the Home button on your remote and open Settings (the gear icon on the right of the top menu).
- Select Applications.
- Select Manage Installed Applications.
- Scroll to the app you want to fix and select it.
- Select Force Stop first. This closes the app completely so it is not holding files open.
- Select Clear Cache. The cache figure on that screen should drop to zero or close to it.
- Press Home and open the app again.
Start with the app that is actually giving you trouble. If your IPTV player freezes when it loads the channel list, clear that player's cache before touching anything else.
How to clear all app caches at once
On the same Manage Installed Applications screen, newer Fire TV software shows a Clear all Application Caches option. Select it, then Confirm. It runs through every installed app and is the fastest fix when the whole device feels sluggish rather than one app. Amazon documents both methods on its Fire TV help page for clearing app data and cache.
If you do not see that option, your device is on older software or does not offer it. Clearing the heaviest apps one by one gets you the same result. Streaming apps and IPTV players are usually the biggest, because they cache artwork for thousands of titles and channels.
One more thing Amazon notes: when storage runs low, Fire TV clears the cache automatically for apps you have not opened in more than 30 days. You cannot turn that off, and it will not touch the apps you use every day, which are the ones most likely to need it.
Clear cache vs clear data: the difference that matters
Right under Clear Cache sits Clear Data. They look similar and they are not.
| Clear Cache | Clear Data | |
|---|---|---|
| What it removes | Temporary files the app can rebuild | Everything the app has saved, cache included |
| Signs you out | No | Yes |
| Keeps your settings | Yes | No, the app returns to how it was on first install |
| IPTV player impact | Channel logos and lists reload once | Your login, playlist or portal details, favorites and guide settings are gone |
| When to use it | First step for any slow or glitchy app | Only when clearing the cache did not help |
For an IPTV app, clearing data means you have to enter your login details or playlist link again, re-add the guide source if your app needs one, and rebuild your favorites list. Before you press it, make sure you have your account details to hand. If you are a HoxyTV subscriber and cannot find them, our support team can resend them.
Restart the Firestick before you clear anything
A restart fixes a surprising share of slow Firestick problems on its own, because it closes every background app and frees up memory. It is the first thing worth trying, and it takes under a minute. There are three ways to do it:
- From the menu: Settings, then My Fire TV, then Restart.
- From the remote: hold the Select (center) button and Play/Pause together for about five seconds, until the screen goes dark.
- At the plug: unplug the Firestick's power cable, wait a few seconds, and plug it back in. Use this one when the screen is frozen and the remote does nothing.
A restart does not clear the app cache. It clears memory. The two fix different problems, which is why a restart plus a cache clear is the usual combination when a Firestick has been slow for a while.
Why is my Firestick so slow? The usual causes
| Symptom | Likely cause | What to try |
|---|---|---|
| Everything is sluggish, menus lag | Too many apps running in the background, or storage nearly full | Restart, then clear all app caches |
| One app freezes or crashes | Corrupted cache in that app | Force Stop, then Clear Cache for that app |
| An app still fails after clearing its cache | Bad saved settings | Clear Data, then sign in again |
| Low storage warning | Big caches plus apps you no longer use | Clear caches and uninstall apps you do not open |
| Video stops to load but menus are fine | Network, not the device | See the buffering section below |
You can see how much free storage is left under Settings, My Fire TV, About. If it is almost full, clearing caches buys you time, but uninstalling apps you no longer use is the lasting fix.
Does clearing the cache stop buffering?
Usually not. Buffering happens when video arrives slower than the Firestick plays it, and that is almost always about the connection: weak Wi-Fi where the TV sits, a busy home network, or the stream itself. A bloated cache can make an app slow to open or slow to change channels, but once a stream is playing, the cache has little to do with it.
If the picture keeps pausing to load, work on the network side instead: move the router closer or use a wired adapter, and check whether other devices are streaming or downloading at the same time. Our guide to fixing IPTV buffering walks through that step by step. It is also worth checking you have not hit your plan's device limit, since a second screen can cut the first one off. That is explained in how multiple connections work.
How often should you clear the cache?
There is no schedule you need to keep. Clear it when an app starts misbehaving or the device gets slow, not as a weekly chore. Clearing it constantly just makes each app reload everything from scratch, which makes the first launch slower rather than faster. For most people, a restart now and then plus a cache clear when something breaks is plenty.
If the problem is the IPTV app itself
If a single IPTV player keeps failing even after you clear its cache and data, the app may be out of date or simply not a good fit for your device. Reinstalling it is a clean next step: uninstall from the same Manage Installed Applications screen, then install it again and add your details. Our Firestick IPTV install guide covers the setup from the beginning, and the Fire TV tutorial has the HoxyTV-specific steps. If the channel guide comes up empty after a reset, our EPG guide explains how guide data gets back into the app.
HoxyTV lists Amazon Firestick and Fire TV among its supported devices and offers free setup assistance, so if you get stuck halfway through, ask support rather than guessing.
Frequently asked questions
Should I clear the cache on my Fire Stick?
Yes, when an app is slow, freezing or showing stale information, or when you get a low storage warning. It is safe and you lose nothing important. There is no need to do it on a routine basis if everything works.
Will I lose anything if I clear the cache?
No. The cache only holds temporary files the app can download again, so your login, settings and favorites stay put. Clear Data is the option that removes those.
How do I clear my Fire Stick cache all at once?
Go to Settings, Applications, Manage Installed Applications and choose Clear all Application Caches, then Confirm. If your device does not show that option, clear the largest apps one at a time.
Does restarting a Firestick clear the cache?
No. A restart clears the device's memory and closes background apps, but the app caches stay on storage. Restart first, and if the problem remains, clear the cache of the app involved.
Does clearing the cache stop buffering?
Rarely. Buffering is nearly always a network or stream issue. Clearing the cache helps with apps that are slow to open or crash, not with video that pauses to load.
