## When to Use
With device usage statistics APIs, you can have a better understanding of the application, notification, and system usage. For example, in application usage statistics, you can query the application usage, event log, and bundle group.
The application records (usage history statistics and event records) cached by components are updated to the database for persistent storage within 30 minutes after an event is reported.
## Available APIs
