The PS4 is an incredible console, that makes full use of its advantageous hardware and the fact that its exclusives gallery is filled to the brim with some of the most engaging and compelling games like God of War, Gran Turismo 7 and Sport, Ratchet & Clank, Horizon: Zero Dawn and many more. These factors make it the console to have and this is evident from the sales numbers that Sony has posted over the seven years that the console was manufactured; it overtook Xbox One and even its predecessor, the former sales heavyweight PS2 to sell nearly 115 million units. That’s a lot of consoles. But there are certain issues that plague the seemingly undefeated console, like its cache, which can slow the console down. Here’s how to clear cache on PS4.

For those who don’t know much about the inner machinations of a console or any other computer for that matter, a cache is basically a part of the installed memory on the system which stores temporary data which is accessed frequently. Cache makes it possible for the user to swiftly and instantaneously access that data; be it a paused game or a download in the tray that you want to keep checks on. Whatever the data, it’s the cache’s job to make it accessible in one instant and keep it loaded and ready to view so the user does not have to wait for the data to load or show up.

As you can imagine, the cache gets pretty loaded and full during a heavy gaming session on the PS4, and as such, you could notice a performance drop once the minutes begin to roll by and the Warzone lobby gets more and more interesting and heated. The performance drop has nothing to do with the hardware, the CPU or the GPU; the noisy fan working at maximum RPM should tell you that both of the units aren’t the problem. It’s just that the cache is getting overloaded as the temporary data being stored is slowly getting to the full capacity. It certainly won’t shut down the console or dramatically affect performance, but users have reported performance drops, especially when they switch apps or quickly jump to the app tray to check out that screenshot or recording for a quick upload, when the console starts to lag a bit.

So, here’s how to clear cache on PS4,

How to clear cache on PS4

There is only one way to clear the cache on PS4, and it is as simple as turning the console off. Literally. You have to turn the console off to clear the cache. Here’s how,

The cache is actually cleared every time you shut down the PS4, so performance drops shouldn’t be a recurring or permanent issue that ruins the game time with your friends. However, should you notice a particularly bad lag during switching to apps or simply accessing the app tray during an intense gaming session, if possible, excuse yourself from the game for five minutes and try this method to clear the cache.

Start by jumping off the game and ejecting any disk that might be in the console. Once that has been ejected, prepare to shut down the console (by suspending any background applications or pausing any downloads). Power off the console; pay extra attention to the blinking lights situation that goes on with every PS4 regardless of its model year or memory. Whether it’s a simple PS4, a PS4 Slim or PS4 Pro, the light will first start to dim down (staying white) and when it shutting down the internal components, it will start to blink.

Once the blinking has subsided and it has completely powered down, unplug the HDMI cable from the back (positions of the ports may vary from model to model; especially in the Slim and Pro models). After the HDMI has been plugged out, unplug the power cable, which should be on the extreme left of the back of the console. Unplug it as well and let the console rest for a minute or two before plugging up the peripherals and cords once again. 

After plugging it in, wait for a few seconds before turning on the console. You can turn on using both the physical button on the PS4 console or by pressing the PS button on the DualShock 4 controller, which acts as a remote to turn on the console. Be sure that power is being supplied and all the cables are properly connected. Let the console run its ‘Epilepsy warning’ and the whole start-up sequence. Once it turns on, the cache will have been cleared and the console will be back running on full capacity.

You can test out the performance by switching between apps quickly and by booting up a heavy game. There will be no performance drops or lags once the console has been freshly powered on.

Pressing L1+R1 while booting

There are many threads and chat boards on the internet that claim that cache can be cleaned and the performance can be increased as well by long pressing both the upper trigger keys (L1+R1) when booting up a game. Many threads refer to Rockstar Games (creators of the Grand Theft Auto (GTA) and Red Dead Redemption (RDR) series) as being the developer which suggested users this fix to clear out the cache and increase game performance of the console. While this hasn’t been proved to make a difference, we suppose you could try it out and see for yourself if any difference in performance can be seen. As of this, there is no other hack or way to clear out the cache or increase the performance; the internal hardware of the PS4 should suffice whatever game or task you throw at it.

In a nutshell,

Turning off and back on again (also restarting) can clear out your cache in a matter of minutes. We all know the wait you have to go through to watch the PS4 power down, but it can give you a cleaned cache and revitalized performance for the next rounds of Fall Guys or Call of Duty: Warzone.
