Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/581

The FAQ How much battery does the Android app use? seems to imply that F-droid consumes additional battery, due to lack of FCM. Could this be made explicit, for a new F-droid user that doesn't have the common knowledge that FCM won't work and follows a direct link (so won't read the previous FAQ)?

The bold words would make it explicit in the FAQ. The important part is the link to the doc, where Firebase is mentioned and the background story is explained.

If you use the ntfy.sh server, and you don't use the instant delivery feature, the Android/iOS app uses no additional battery, since Firebase Cloud Messaging (FCM) is used. If you use your own server, or you use instant delivery (Android only), or install from F-droid (which does not support FCM), the app has to maintain a constant connection to the server, which consumes about 0-1% of battery in 17h of use (on my phone). There has been a ton of testing and improvement around this. I think it's pretty decent now.
