It's been a massive battery drain for me as I have no Google services. It's a known bug. You can't really turn off that drain either in favor of getting messages later.

Other apps like Threema or Telegram might delay messages sometimes, but at least they keep my device operational. If I'm punished for opting out of Google's spying, I at least want to choose the punishment.
