After having the increased battery usage that came with the 13.xx betas and the 13.22 final fixed by hard resetting my Fenix 7 Saphire Solar the issue reappeared yesterday after the watch crashed when deleting a course.
Another hard reset fixed things and of course I have to spent 1-2h now setting up the watch again. This time around I removed the secure config file I had on my watch since it was part of the beta testing cycles.
I wish there was another way but for now the only way I have found to use 13.22 without losing 1% of batter per hour is to perform a hard reset after every crash.
