Is there any effective difference between disabling an app's notifications in the app itself vs. via Android's per-app notifications panel?
I've defaulted to first trying to disable any notifications in the apps themselves, attacking at the root, rather than relying on the Android OS per-app notifications permissions. My thought is that doing it this way stops the app from sending a notification at all -- and thus, less battery used -- vs. Android merely hiding some notifications from view.
The downside to this is the inconvenience in having to go into the app itself and wander around the settings, with notification settings not always the simplest to reach, and in some cases, the app doesn't have granularity of notifications to tweak or limit.
Is there any basis to this, or is there no effective difference to managing/disabling notifications via Android's per-app settings?
