Have to say that having a ntfy server with proper networking (looking at you, Oracle free tier) and going all in on UnifiedPush has done wonders for mobile phone battery life.
After switching to Molly+MollySocket, I could probably go two days again, opposed to the battery warning on the first evening a couple weeks ago.
Without Mastodon and Lemmy, probably 3 days without a stretch. I still wonder if this Pixel 7a battery will last the full OS support period, new it was 20% / day with doomscrolling.
