Catalina Notes.app draining battery?

After upgrading to Catalina, I noticed that my MacBook Pro (13" with touchbar) would go from 100% battery to nearly zero in just about 30 minutes. The fans would be running like crazy. Using Activity Monitor, I tracked the culprit down to Apple Notes:
What the heck is going on here? Any idea how I can resolve this? I should also mention that this is reproducible every time… just open up notes and the fans will start going berserk.
UPDATE 1: I just installed the October 15 Supplemental update for Catalina, and there's no difference.
UPDATE 2: Booted into safe mode (hold shift at start up) and this was still the case. Energy Impact of Notes.app spiked to 300+ right away.
UPDATE 3: I reset SMC and PRAM/NVRAM. No difference.
解決
All seems to be resolved by toggling off and then back on the iCloud sync for Notes (In Catalina, this is found in the Apple ID section of System Preferences):
- Turn off Notes iCloud sync
- Turn it back on
- Open Notes.app
- Be momentarily terrified because all your notes have vanished
- Watch as they trickle in from iCloud
Running Activity Monitor now lists Notes as barely having any energy impact whatsoever. Hooray!
BONUS: Back Up Your Notes
I was reluctant to try this method because I was terrified that I would introduce some sync problem and wipe out my notes. As Apple provides no easy way to make a local backup/export of your notes, I felt that this was a reasonable worry.
Eventually, I found this little utility that makes .txt
files (with HTML inside) of all of your notes (WARNING: it omits any images or attached files). It ain't great, but it worked and helped to put me at ease.
Apple also provides a way of downloading your iCloud data on their Data and Privacy site… which I initiated, but have yet to receive the download link. According to Apple, this could take up to 7 days.
