As SgtSurehand has mentioned, the hassle could be more than the effort, because the difference isn't very much.
In my practical experience most of the time in standby 1% battery lasts 1 hour.
Sometimes 1% battery in standby last 1:20 h.
Without UnifiedPush in standby 1% battery lasts never more than 1:00 h.
In other words:
If it's not important to save a lot of energy and only Molly-FOSS could use UnifiedPush because you don't use any other app that supports UnifiedPush, then it's not really worth it.
BTW: Nowadays, almost nobody makes phone calls anymore, not even via Messenger…
However, if you are one of those who want to be reachable by phone even via Messenger, then UnifiedPush is not ideal because it has a disadvantage:
It cannot transfer calls directly, it can only notify you of the call attempt.
And passing on a call attempt notification wakes up Molly and if the caller then tries to reach you by phone again, then (!) Molly rings.
So only on the caller's 2nd or 3rd attempt.
