When? Each such check is draining battery, and it defats the prupose of low power mode if frequent.
The check should ideally only be done once, just before suspending the tab. Of course, if this will still strain battery, or there is a better way to approach this then please advise.
Still not clear what this relates to or how we can determine the status.
Here is a description related to how Auto Tab Discard works:
This extension uses the native method (requests that the browser discards a tab), and the browser then handles the process. When such a request is received, the browser stores the tab's data (such as scroll position or HTML, CSS, and JS content) in a binary object and removes it from memory, so there is no activity from the tab anymore. In contrast, other methods for tab discarding involve replacing it with an internal lighter page. However, this approach has several drawbacks. For example, the extension must handle restoring process, and the tab still occupies memory like a lightweight tab. Additionally, the extension manages the crash recovery itself.
