If you’re using an Android smartphone with very limited storage, you probably have the habit of checking how much space each of your apps occupy. You will also have to regularly clear the cache of space hogging culprit apps such as Facebook, to free up extra storage for more apps. With Android 8.1 Oreo, your phone will do the spring cleaning for you.
Spotted by XDA Developers, the feature is known as “downgrading” inactive apps. That definitely doesn’t sound like the case, but it is a handy feature on Android 8.1. With that version of Android, the system will automatically trigger the “downgrade” after it detects inactivity on apps for a certain amount of days. The trigger will thereby clear the cache of the inactive apps.
Cache consists of temporary files that make an app load faster and run more efficiently. Cleaner apps are known to clear caches and app data, which might actually harm your phone in the long run as the apps will constantly have to reload data. But the new feature on Android 8.1 Oreo should do no harm far as we know. In fact, it will actually benefit smartphones with low storage space.
