I spent a fair bit of time on what I believe is the same issue. I even installed an Adafruit RTC and that didn't seem to solve the issue. At the moment, I have the system on a UPS (which is huge and probably uses more power than my Console, Adapter/Logger module and the RPi Zero W). My UPS battery is dying so I will have to replace it soon if I plan to continue to use it.
I am not so much worried about losing data - though I can understand preserving the data is important for many people - but I just want the darn thing to start working again when the power comes back on. If I'm not around, it may go for many hours after the power has been restored, not working properly, until I clear the logger memory. I'll be interested in seeing the comments!
