Lengthy-time Android energy customers shall be all too accustomed to the “transparent cache” choice in restoration, however thank you to a couple fresh adjustments to how Android works, the cache partition is a factor of the previous. Right here’s why.
Historically, Android would obtain an replace, retailer it at the cache partition, after which use it on the device partition when the tool was once rebooted. This procedure takes a bit little bit of time, then the OS has to “optimize” after the reboot is entire in an effort to blank up the set up. It’s now not a unhealthy device, consistent with se—it’s simply now not as environment friendly because it may well be.
Beginning with Android Nougat, Google carried out a brand new replace device that mimics what the corporate has been the use of on Chrome OS for years. This new seamless replace device is all of the reason why the cache partition is now not wanted.
Whilst we now have a for much longer rationalization on what the brand new replace device is and the way it works, right here’s the thin. The brand new device nonetheless makes use of two walls, however they’re each device walls. As an alternative of downloading an replace to the cache partition, after which making use of it the present device partition, the device has two an identical device walls. The replace report is then carried out to the dormant partition whilst you proceed to make use of the prevailing device partition like commonplace. Then, whilst you reboot the telephone to finish the replace, the device walls are merely swapped—the up to date partition turns into the brand new primary device partition, whilst the opposite turns into dormant till some other replace is launched.

This manner, as a substitute of the telephone desiring to be out of fee whilst it updates, all of the procedure occurs within the background. The replace is downloaded and carried out whilst you proceed to make use of your telephone, and a straightforward reboot is all it takes to switch the walls. The most productive phase is this reboot doesn’t take for much longer than a regular reboot, so that you’re again in trade inside of a couple of seconds.
This new device gets rid of the will for a cache partition altogether, so in case you’re the use of a more moderen telephone this is making the most of seamless updates, then you definately received’t see the “transparent cache” choice in restoration.
After all, this best applies to new telephones—older fashions that shipped with a cache partition will proceed to make use of stated partition and the normal replace type, without reference to what model of Android they’re the use of.
