Some Android phones store temporary files used for things like OS updates in a cache partition. You may have seen recommendations across the web indicating that you are clearing this partition from time to time, but is it a good idea?
What is the system cache and what data is stored there?
Some days ago before Nougat, Android used a system cache to store system update files. Android has since moved away from it, and prefers another method of installing updates.
Many modern phones do not even have a system cache now. If your have a system cache, it will be on a separate partition from your primary phone storage. Files stored there do not record any user accessible space cleaning. The system cache does not allow you to download any new apps, store files or save more cat photos.
The system cache also differs from the cached app data, which is data stored by apps and specific to the current app. For example, Spotify stores streamed music in its cache file for faster (and offline) playback. Each app has its own cache file that is separate from the system's cache file and takes user space. Clearing this cache is a great way to free up space. Just keep in mind that the app will build up the cache when you use it, so it's not a permanent fix if you need more space.

Are you going to dry the system cache?
Drying the system cache does not cause any problems, but it is also unlikely that it will help much. The files stored there allow your device to access commonly referred information without having to rebuild it all the time. If you dry the cache, the system will rebuild these files the next time the phone needs them (just like with the app cache).
While we do not recommend that you clear the system cache, especially regularly or for no reason, there are times when it can help. For example, sometimes these files get damaged and cause problems. If you have problems with your phone and you are okay, you are welcome to try.
How to wipe your phone's system cache
As mentioned, some phones do not have a system cache partition. We tested several phones, and only those that OnePlus and Alcatel allowed us to clear the cache. The Samsung Galaxy, Google Pixel and phones from Oppo and Honor had no such alternative, for example. As with many things in Android, your mileage may vary.
To delete the phone system cache, you must first restart the device in the recovery mode. To do so, turn off the device, and then press and hold the power and volume button until the phone is turned on again. If this does not work, the button combination may be different on your device – refer to the user manual if necessary.
You may be asked to enter a password. If so, enter your lock screen password to enter recovery mode.
On some devices, the touch screen may work in reset, so you can press the option you want to select. On others, you have to navigate in different options by pressing the volume up and down, with the power button as the "enter" button.
From here, the process depends on your specific device, but you "I am looking for the" Dry Cache "option of any kind. You may need to consult the documentation for your particular device if you have problems.
Once you have found the right option, select it.This is an irrevocable decision, some devices may ask you to confirm that you want to continue.When you have confirmed, just take a few seconds to dry the partition clean.
When it is ready, use the reset restart option to restart the phone to the operating system.The phone will start normally and you are completely busy!
