So far 14.20 has been positive for me with the battery. Doing spot checks shows it back to .3 percent per hour and staying consistent.
Mine is back to normal - have to say, it took them a while but kudos to Garmin for getting it fixed. I even got an email notifying me of the fix!
A little more communication early on - such as posting on here/social media that they were working on the problem - would have been appreciated.
Now... I'm disabling auto-update just in case...
for me 14.20 is crap. i can't believe that garmin is not able to simply fix things without messing up other things.
i was one of the lucky people who did not have problems with battery drain. with fw 13.40 and 14.10 i had less than 5% per day battery drain (before it was about 6%) (using a CIQ watch face). now with 14.20 i have 8% per day.
