Nvidia Shield IPTV vs Android TV Box: Which Streams Smoother?
The Nvidia Shield is still the smoothest Android box for IPTV, but a certified mid-range Android TV box gets surprisingly close for far less money. Here's how…
To clear cache on a Firestick, go to Settings > Applications > Manage Installed Applications, pick your IPTV app and choose Clear cache. It takes under a minute, keeps your login details intact, and is the single quickest fix for an IPTV app that has started to lag, stutter or crawl through its menus.
This guide walks you through the whole process step by step, explains the difference between clearing cache and clearing data (one of them will log you out), and covers the other housekeeping jobs that keep a Fire TV Stick feeling snappy. Whether you use TiviMate, IPTV Smarters or another player with your SkyStreamHubReborn subscription, the steps are the same.
Key Takeaways
- Clearing cache removes temporary files only; your IPTV login and settings stay put.
- Clearing data is a full reset of that app, so have your Xtream or M3U details handy first.
- Firesticks have limited storage, so a quick restart plus a cache clear once a month goes a long way.
- If the app is fast but streams still buffer, the problem is more likely your connection than your cache.
Why Your Firestick Gets Slow in the First Place 🐢
Every app on your Fire TV Stick stores temporary files, called cache, to speed things up. For an IPTV app, that means channel logos, EPG data, thumbnails for movies and series, and bits of recently viewed streams. On a package like DELTA with 24,000 live channels and over 41,000 movies, or Trex with its 54,948 channels, that cache can grow surprisingly large.
The trouble is that a Firestick does not have a great deal of storage to begin with. Once the cache from your IPTV app, plus Prime Video, Netflix and whatever else you have installed, starts eating into the free space, Fire OS has to work harder. Menus hesitate, the guide takes an age to open, and the app may even close itself without warning. Clearing the cache gives that space back.
How to Clear Cache on Firestick: Step by Step 🧹
The menu names below are from the current Fire OS layout. Older sticks word things slightly differently, but the path is essentially the same.
- From the Fire TV home screen, press the Home button on your remote and move to the Settings cog on the right.
- Select Applications.
- Choose Manage Installed Applications.
- Scroll down and select your IPTV app, for example TiviMate, IPTV Smarters or Purple Player.
- Select Clear cache. The number next to it drops to zero almost instantly.
- Press Home, then open the app again. The first launch may take a touch longer while it rebuilds the EPG and logos, which is completely normal.
That is genuinely all there is to it. You do not need to re-enter your username, password or playlist URL, and any favourites or custom channel groups you set up in TiviMate will still be there.
Which apps should you clear?
Start with your main IPTV player, then work down the list looking at the cache sizes shown on each app's page. Web browsers such as Silk, the Amazon Photos app and any catch-up apps tend to be the biggest offenders. There is no harm in clearing cache on every app you use regularly.
Clear Cache vs Clear Data: Know the Difference ⚠️
Right underneath Clear cache you will see Clear data. They sound similar but do very different things, and picking the wrong one is the most common mistake people make.
| Action | What it removes | Keeps your login? | When to use it |
|---|---|---|---|
| Clear cache | Temporary files: logos, thumbnails, cached EPG, stream buffers | Yes | First step for any slowdown, safe to do monthly |
| Clear data | Everything, including login, playlists, favourites and settings | No | App crashes on launch, corrupted playlist, or you want a fresh start |
| Uninstall and reinstall | The whole app and all its data | No | App will not open at all, or you are updating to a newer build |
| Restart Firestick | Nothing stored; just frees memory | Yes | Quick fix for general sluggishness, try before anything else |
Before you clear data: write down your Xtream Codes login (server URL, username, password) or your M3U link. SkyStreamHubReborn delivers these automatically when you subscribe, so check the email or message you received, or ask UK support on WhatsApp or Telegram if you cannot find it.
The Full Firestick Speed-Up Routine 🚀
Clearing cache is the headline fix, but a few extra minutes of housekeeping makes a noticeable difference, especially on an older or lower-spec stick.
1. Restart the stick properly
Pulling the power out and plugging it back in works, but there is a tidier way: go to Settings > My Fire TV > Restart. Alternatively, hold Select and Play/Pause together on the remote for a few seconds. A restart clears the memory that apps have been hogging in the background and is worth doing before any match or PPV event.
2. Remove apps you do not use
In Manage Installed Applications, uninstall anything you have not opened in months. Every app takes up storage even when it is idle, and some run background services that compete with your IPTV player for memory.
3. Turn off background data and video autoplay
Under Settings > Preferences, you can switch off Featured Content autoplay for video and audio. This stops the home screen pre-loading trailers while you are trying to get into your IPTV app. Under Data Monitoring you can also keep an eye on which apps are using the most data.
4. Check for Fire OS and app updates
Go to Settings > My Fire TV > About > Check for Updates. Updates occasionally fix memory leaks that make apps slow down over time. The same applies to your IPTV player; our Android and Firestick app guides with Downloader codes always point to the current builds.
5. Trim your EPG settings
If you use TiviMate, the EPG for tens of thousands of channels is a big chunk of what gets cached. In TiviMate's settings you can reduce how many days of guide data it keeps and how often it refreshes. Most people only need a couple of days ahead. Our TiviMate setup guide covers the recommended settings, and the IPTV Smarters guide does the same for Smarters users.
6. Keep an eye on free storage
Check Settings > My Fire TV > About > Storage. If it is nearly full after you have cleared caches and removed apps, the stick is simply carrying too much. At that point it is worth considering whether a newer, higher-spec model would serve you better.
Did It Work? How to Tell 📊
After clearing cache and restarting, open your IPTV app and try these quick checks:
- Menu speed: scrolling through channel categories should feel immediate, with no pause between presses.
- Guide loading: the EPG should populate within a short while on first open, and instantly after that.
- Channel switching: hopping between channels should be quick and consistent.
- Stability: the app should stay open through a full match or film without closing itself.
If the menus are now quick but the actual streams still buffer, the cache was not your problem. That points towards your internet connection. As a reminder, SkyStreamHubReborn recommends at least 20 Mbps download, 1–5 Mbps upload and a ping of 20–50 ms. Run a speed test on the Firestick itself rather than your phone, because a stick tucked behind a TV often gets a weaker Wi-Fi signal than you would expect.
Using a VPN? Every SkyStreamHubReborn subscriber gets a free PIA VPN login. The VPN app has its own cache too, and choosing a server that is geographically close keeps the overhead low. You do not need a VPN for the 3PM Saturday kick-offs on our service, so if you only switched it on for football, try turning it off and see whether things speed up. Our PIA VPN install guide explains the settings.
How Often Should You Clear Cache? 🗓️
There is no hard rule, but a sensible rhythm for most households is:
- Restart: whenever the stick feels sluggish, and before big events.
- Clear cache on your IPTV app: roughly once a month, or whenever the guide starts loading slowly.
- Clear cache on everything else: every couple of months.
- Clear data or reinstall: only when an app misbehaves and a cache clear has not fixed it.
Clearing cache too often is not harmful, but it is also not helpful. The app will just rebuild the same files again, and you will sit through a slower first launch each time for no real gain.
When Clearing Cache Is Not Enough 🔧
If you have done everything above and your Firestick still struggles, work through this short list before assuming the worst:
- Try a different player. Some apps are lighter than others. A quick swap between TiviMate and Smarters, using the same Xtream login, will tell you whether the app or the stick is the bottleneck.
- Check the stick's power supply. Running a Firestick from a TV's USB port rather than the supplied mains adapter can cause odd slowdowns and random restarts.
- Consider a wired adapter. An Ethernet adapter for Fire TV takes Wi-Fi out of the equation entirely.
- Ask support. If you are a SkyStreamHubReborn customer, send a message on WhatsApp or Telegram with your device model and the app you are using. Our UK team sees these issues every day and can usually point you to the fix quickly.

Final Thoughts
A Firestick is a brilliant little device for IPTV, but it has limited storage and memory, and it fills up quietly over time. Clearing cache is a two-minute job that fixes most of the sluggishness people complain about, and pairing it with a monthly restart and a little app tidying keeps things running the way they did on day one.
If you are getting set up for the first time, or you are looking for a no-contract service with instant delivery and proper UK support, take a look at our current plans. Every package comes with up to three connections, test lines are available, and we are happy to help you get your Firestick running smoothly from the start.
❓ Frequently Asked Questions
Does clearing cache on a Firestick delete my IPTV login?
No. Clearing cache only removes temporary files such as logos and guide data. Your username, password, playlist and favourites are kept. It is Clear data that resets the app and logs you out.
How do I clear cache on all apps on a Firestick at once?
Fire OS does not have a single button for every app. You need to go into Settings, Applications, Manage Installed Applications and clear each one individually, starting with the apps showing the largest cache sizes.
Will clearing cache stop my IPTV from buffering?
It helps if the app itself is slow, crashing or struggling to open the guide. If streams play but keep pausing, the cause is more likely your internet connection, so check your speed on the Firestick itself.
How often should I clear the cache on my Firestick for IPTV?
About once a month is plenty for your main IPTV app, plus a restart whenever the stick feels sluggish or before a big match. Clearing it more often simply forces the app to rebuild the same files.
Why does TiviMate take longer to open after I clear the cache?
The first launch has to download channel logos and EPG data again, which takes a moment on large packages. After that initial rebuild it should be quicker than before.
What should I do if clearing cache does not speed up my Firestick?
Restart the stick, remove unused apps, check for Fire OS updates and look at free storage. If it is still slow, try a different IPTV player or contact support on WhatsApp or Telegram with your device details.
