The Amazon FireStick has become one of the most popular streaming devices in the world, thanks to its affordability, compact design, and ability to turn any regular TV into a smart entertainment hub. Whether you’re binge-watching your favorite shows, streaming live sports, or using apps like YouTube and music platforms, the FireStick can handle it all.
But like any tech gadget, over time, your FireStick might start slowing down. Apps may take longer to open, menus lag, buffering becomes frequent, and the overall experience feels less smooth than when it was new.
The good news? You don’t have to rush out and buy a new device. With a few simple tweaks and maintenance tips, you can restore your FireStick’s speed and improve performance dramatically.
In this comprehensive guide, we’ll explain why your FireStick gets slow, and how to speed up your slow FireStick step by step in 2025.
📌 Why Does Your FireStick Slow Down Over Time?
Before diving into fixes, it’s important to understand why a FireStick might start underperforming:
1️⃣ Limited Storage
FireStick devices have limited internal storage, usually around 8GB. Over time, this fills up with apps, app data, cache files, and updates.
2️⃣ Background Apps
Some apps keep running in the background even after you close them, using memory and resources unnecessarily.
3️⃣ Cache Build-up
Temporary files, thumbnails, and cached data accumulate as you stream and browse, slowing down the device.
4️⃣ Outdated Software
If your FireStick’s operating system or apps aren’t updated, bugs and inefficiencies can affect performance.
5️⃣ Overheating
When overworked, FireSticks can heat up, causing apps to lag or crash.
6️⃣ Unnecessary Features
Features like animations, app monitoring, and automatic data collection consume resources in the background.
🚀 20 Proven Ways to Speed Up a Slow FireStick
Let’s get right into actionable tips you can use today to speed up your FireStick and improve your streaming experience.
1️⃣ Restart Your FireStick Regularly
Many users keep their FireStick plugged in 24/7. Restarting it clears RAM, closes background processes, and gives the system a fresh start.
How to do it:
-
Go to Settings → My Fire TV → Restart
2️⃣ Clear App Cache and Data
Over time, apps accumulate cache and temporary files. Clearing them helps improve performance.
Steps:
-
Go to Settings → Applications → Manage Installed Applications
-
Select an app
-
Choose Clear Cache
-
Optionally, select Clear Data (this resets the app to default)
3️⃣ Force Stop Background Apps
Some apps remain active in the background even when not in use, eating up resources.
To force stop:
-
Go to Manage Installed Applications
-
Select an app
-
Choose Force Stop
4️⃣ Delete Unused Apps
Free up storage space by removing apps you no longer use.
How to uninstall:
-
Settings → Applications → Manage Installed Applications
-
Select an app
-
Choose Uninstall
5️⃣ Turn Off App Usage Data Collection
FireStick collects data about your app usage, which consumes resources.
Disable it:
-
Go to Settings → Preferences → Privacy Settings
-
Turn off Collect App Usage Data
6️⃣ Turn Off Interest-Based Ads
Disabling interest-based ads reduces background activity and speeds up the FireStick.
Steps:
-
Preferences → Privacy Settings
-
Turn off Interest-based Ads
7️⃣ Disable Notifications
Unnecessary notifications interrupt your streaming and use resources.
To disable:
-
Settings → Preferences → Notification Settings
-
Turn off Do Not Interrupt
8️⃣ Disable Automatic App Updates
While keeping apps updated is important, constant background updates slow your device. You can update manually when needed.
How to disable:
-
Settings → Applications → Appstore
-
Turn off Automatic Updates
9️⃣ Use a Lightweight Launcher (Optional for Advanced Users)
Default FireStick interface can feel heavy. Replacing it with a lightweight launcher can improve performance, but this is recommended for experienced users.
🔟 Keep Software Updated
Make sure your FireStick is running the latest version of its operating system.
Check for updates:
-
Settings → My Fire TV → About → Check for Updates
1️⃣1️⃣ Turn Off Automatic Video Previews
Previews on the home screen can slow down performance.
To disable:
-
Settings → Preferences → Featured Content
-
Turn off Allow Video Autoplay and Allow Audio Autoplay
1️⃣2️⃣ Use the Background Apps & Process List Tool
This tool (available in the Fire TV Appstore) lets you see all running apps and stop unnecessary ones with a click.
1️⃣3️⃣ Avoid Overloading with Too Many Add-ons
If you use third-party apps or Kodi, avoid installing too many add-ons simultaneously. They occupy space and processing power.
1️⃣4️⃣ Clear Home Screen clutter
Remove unnecessary items like extra widgets, apps, or shortcuts from your FireStick home screen.
1️⃣5️⃣ Use a Good Wi-Fi Connection
Sometimes slow streaming is a Wi-Fi issue rather than a FireStick problem. Ensure you have a strong, stable connection. If possible, use the 5GHz band for faster speeds.
1️⃣6️⃣ Avoid Overheating
If your FireStick gets too hot:
-
Unplug it when not in use.
-
Use an HDMI extender to improve airflow.
-
Keep it away from other electronic devices.
1️⃣7️⃣ Restart Router Periodically
Slow internet affects streaming speeds. Restarting your router clears temporary glitches and improves connection quality.
1️⃣8️⃣ Clear Browser Cache (If You Use a Web Browser)
If you use browsers like Silk or Firefox on your FireStick:
-
Open the browser.
-
Go to Settings.
-
Clear cache and browsing data.
1️⃣9️⃣ Remove Screensaver and Reduce Animation Effects
Screensavers and transition animations use processing power.
To disable:
-
Settings → Display & Sounds → Screensaver
-
Set Start Time to Never
And reduce animations by:
-
Settings → Accessibility
-
Turn off Screen Magnifier and other unnecessary effects.
2️⃣0️⃣ Perform a Factory Reset (As a Last Resort)
If all else fails, a factory reset can restore your FireStick to its original state and clear all clutter.
How to reset:
-
Settings → My Fire TV → Reset to Factory Defaults
Warning: This will erase all apps, data, and settings.
