- Use the built-in Memory Optimizer to close background processes and quickly clean up RAM.
- Manual removal of unnecessary applications and emptying of the browser cache and installed apps.
- Performing full electrical resets by disconnecting the device from the power supply to refresh the temporary memory.

Have you noticed that your LG TV isn't as fast as it used to be? It's normal to start noticing that menus are sluggish or that apps freeze right when a movie starts. Even though it looks like just a screen, inside it has a processor and memory that, like a mobile phone, gets overloaded with unnecessary digital clutter and processes.
The good news is that you don't need to spend money on a new model or be a computer expert to fix it. WebOS comes with some built-in tools and DIY tricks that let you clean things up, get rid of accumulated clutter, and restore that smooth performance we all miss. With a couple of simple routines, you can get your Smart TV running smoothly again, without those annoying stutters.
Why is your Smart TV running out of space and memory?

Basically, we're dealing with a miniaturized computer. It has RAM , which is responsible for making everything work in real time, and ROM , where the operating system and applications are stored. The problem is that internal space is usually quite limited, and a large portion of it is already taken up by the manufacturer.
With daily use, apps leave behind a kind of "crumb" called cache data . These files help things load faster, but when too many accumulate, they have the opposite effect and slow down the entire system. Furthermore, if you have many apps open in the background, the RAM will run out and the TV will start displaying low memory warnings , even preventing you from installing critical updates.
How to know how much space you really have left

Before you start deleting things willy-nilly, it's a good idea to check your memory status. On LG TVs, the path may vary depending on the version, but usually you just need to press the settings button, go to All Settings , enter the General section, and look for the Devices or TV Management section. There, under TV Information , you'll see how much free space you have left.
As a general rule, it's advisable to keep at least 100 to 500 MB of free space to prevent the system from becoming overloaded. If you see the space displayed in red, it's a clear sign that you need to perform a thorough cleanup or consider using external storage.
The Memory Optimizer: the fast track

For those who don't want to complicate things, LG includes an official tool called Memory Optimizer . This feature is like giving your TV a boost of energy, as it closes invisible processes and clears part of the cache in one fell swoop.
- In OLED models: Go to Settings > General > OLED Care > Memory Optimizer.
- In other models: Look in Settings > Support > Automatic device protection > Memory optimization.
Using this option is completely safe and does not affect the warranty. Ideally, you should make it a regular habit , perhaps every few days, to prevent the system from becoming overloaded and to ensure the menus run smoothly again.
Manual cleaning of applications and junk files
If the optimizer isn't enough, it's time to get down to brass tacks and manually delete what's unnecessary. The first logical step is to uninstall the apps you no longer use; if there's a game or streaming app you haven't opened in months, delete it ruthlessly from the applications menu.
Another critical point is the cache of each app. While not all models allow you to clear it with a button, many let you go to the app's advanced settings and select "Clear cache." If your model is older and doesn't have this option, the trick is to uninstall and reinstall the largest app so it starts fresh and without any bloatware.
Don't forget the built-in web browser either . Cookies and browsing history take up space and can slow down your internet connection. Go into your browser settings and choose the option to clear your Smart TV's browsing history to free up those extra megabytes.
Advanced tricks to boost performance
There are more radical ways to optimize your TV. One of them is to perform a complete power reset . Turning the TV off with the remote isn't a restart; the device enters sleep mode and the RAM continues to store data. To truly clean it, you must unplug it for at least a minute. This forces the system to boot from scratch and clears any unresponsive processes.
For the most demanding users or those using an external device (like a Chromecast or Fire Stick), there's a trick to disabling user agreements . If you go to Settings > Support > Privacy and Terms and uncheck the boxes, the TV stops sending data to LG and closes background processes, turning it into a much faster "dumb TV," although you'll lose features like AirPlay or the app store.
Habits to prevent your LG from slowing down again
To avoid having to perform deep cleanups every month, it's best to maintain good digital hygiene. Get into the habit of closing apps you're no longer using instead of switching between them. It's also essential to update an LG Smart TV with webOS , as LG regularly releases patches that optimize memory management.
If internal storage is still an issue, you can connect a USB flash drive or an external hard drive . While not all apps can be moved there, it's useful for downloading multimedia content and preventing the internal ROM from filling up with large videos or photos.
Keeping your TV clean by using the optimizer, removing outdated apps, and performing occasional power cycles is key to a smooth user experience. Combining these steps with regular system updates and browser cache management will ensure your Smart TV runs as smoothly as the day you bought it, preventing crashes and optimizing available storage space.
