What is phone partition cache and why would you wipe it?

The cache partition is a system’s directory that contains most of the temporary files, logs data from various applications on your Android device.  There can also be left over files from the previous Android update and this may create some issues such as lag or battery performance because some files/processes that are not intended to be active may be automatically run and consume unwanted resources.  If that happens your device could be trying to use stored files that are not meant for your current version of Android.

Wiping the smartphones cache may provide some added benefits of the OS such as:

• Increased performance of apps
• Getting rid of lag in the user interface
• Apparently random errors and failures
• Increased performance of battery
• Lower resources consumption
