Apps to free up space on your mobile insist you clear cache all the time, but Android cache does not exist exclusively to be clearedhas its reason for being.
we tell you what is the android cache for and why maybe you are not interested in compulsively deleting it because in some way it can help your android mobile apps run faster.
What is the cache for Android?
android apps monopolize your mobile storage space on three frontsall clearly visible from the information window that you will see when you touch any app from Settings > Apps. They are:
-
The app itself: The app itself is growing in size and there is nothing we can do about it except uninstall it and opt for a lightweight app.
-
user data: when we use an application, it generates databases, configuration files and/or any other type of data that is stored in mobile storage. If you delete them, the application remains as if you had just installed it.
-
The hiding-place: Android cache are temporary files that apps download and do not affect your settings. If you delete them, they will be regenerated.
Now, that’s not to say Android cache is a whim. Its operation is the same as any other cache, like that of the browser: they are files, images, videos and any other type of temporary file that is downloaded or generated during the use of an application, and which is kept so there is no need to download or generate it again.
For example, an application that displays data from the Internet will use the cache to not having to download this data from the Internet each time you open it. Downloading it again not only means extra data usage but requires more battery than reading it from mobile cache. Here are some of the possible uses of the cache:
-
internet data: by sav ing them in the cache, the application does not need to download them again each time it is opened, thus saving data and battery.
-
Thumbnails: An application can generate thumbnails (thumbnails) or icons to quickly access them later and not have to generate them again and again.
-
format changes: An application may find it easier to handle a file type in a supported format, so it can use the cache to save a converted copy in that format.
-
half sessions: Some applications – editing, for example – don’t save the final result until you finish editing, but in the meantime they have to save the current state temporarily, in the cache.
-
Temporary data: Some user data is worth saving persistently and some is not. These seconds can be saved in the cache.
Data is stored in cache so that it does not have to be downloaded again, along with other generated files, to optimize resources and does not have to be generated or downloaded again
Cache is also used for make apps faster, a good example of which is the gallery photo cache. Instead of having to read all the photos you have on mobile to display a thumbnail and show it to you in the gallery, mobile generates small thumbnails and is much faster to read. If you delete them, the mobile will generate them again.
That is to say, cache is used to save data, battery, CPU usage and speed up the system, so you should think twice before compulsively deleting it. Clearing the cache will free up space which can be very useful if you’re in a hurry at the time or for fixing specific errors, but for the rest it’s better to let it do its thing. The cache exists for good reasons.
