Signal has the possibility to use its own notification service if Google Play Services are not recognized on install. It runs a background service that might consume more battery. In general:
Notifications can be e2e encrypted by the apps that send them - at least on Android (guess same for iOS). Proton does that.
However, there are reports of American agencies using their surveillance network to combine all notification data to create connections between them. That way they are able to tell who sends a message to whom (by matching exact timestamps) - even if content may be encrypted.
