Let’s figure out how to clear cache on Android phone, and whether it should be done. In the process of using a smartphone running the Android operating system, a large amount of various data is accumulated on the mobile device and stored for various purposes.
Part of the data is stored in a special area of memory – the cache. For example, the browser saves data about visited sites, and when you visit this site again, the browser will open copies of the site’s pages stored in the smartphone’s memory without downloading all the data from the Internet. Due to this, the loading time of web pages is reduced, they open faster, traffic and time are saved.
Applications installed on a mobile device store some data in cache memory: local copies of photos, thumbnails of images, information about the operation of applications, local copies of visited pages on the Internet, game files, etc. During the operation of the operating system and installed applications, information is written to the cache that can be used again on the mobile device. All in all, this is a useful feature to help you quickly access data that is being reused.
Android devices use three types of cache memory:
- Dalvik cache – Dalvik virtual machine cache containing application files for faster startup. This type of cache is automatically recreated on the device.
- System cache – located in the internal memory of the device. Here you can find the data of applications built into the Android operating system.
- Application cache – data of third-party applications downloaded from the Google Play Market. By default, this data is stored in the internal memory of the device.
Along with the obvious benefits of cache memory on a smartphone, this has some negative consequences: the data stored in the cache takes up a significant amount of space in the internal memory of the device. Because of this, with a limited amount of internal memory, there is a lack of free space on the device.
A significant part of the internal memory is occupied by the Android operating system itself, and if the internal memory of the device is small, then there will not be enough free space when the gadget is actively used. When trying to install a new application, or perform other necessary actions, the system will inform the user about the lack of memory on the mobile device. Some programs keep a large number of cached files in memory that take up a lot of disk space.
In earlier versions of Android, you can transfer programs using third-party applications that require root rights. At the same time, further performance of the transferred programs is not guaranteed.
To solve the problem, use the best option: clearing the cache on the device. In addition to freeing up space, deleting data from the cache can help with application errors. Some of the files stored in the cache will no longer be needed, because the user may rarely use some programs on his mobile device.
What does it mean to clear the cache on Android? This means to remove all previously saved data from the cache used by applications on the phone. This operation will not cause any harm to the Android OS or installed applications. It will simply remove additional information from memory, the programs themselves will remain in place.
There are four ways to free internal memory from cached data on mobile devices:
- deleting the entire cache with a system tool;
- clearing the cache in a separate application by a system tool;
- deleting the entire cache on a smartphone, or clearing cached data in individual applications using a third-party program;
- reset mobile device to factory settings.
