V21 update battery drain

Friday night v21 upgrade for my fenix 5 installed. I had to charge my watch that afternoon. At about 5 pm the battery was full. The next morning at 8 am the battery was at 92%. I did a 30 minute strength activity. Upon completion my battery was at 24%. 2 hours later the battery was completely dead. I charged it sunday afternoon. It was full at about 5 pm. I put it on my wrist. My 1 am by vmbattery was at 20%, at 5 am when I woke up again the watch was dead. I plugged it back in. It was fully charged when I unplugged it at 6 pm. It is now 722 pm and I am already at 87%. 

What is happening garmin? I havent been able to track an activity in 2 days because my watch is always charging. 

  • Same with my watch too, I would really like to know what caused it!

    Connect IQ app updated on 24.11. and Connect app on 19.11. could that be the solution??

  • I'm having very bad battery life as well but I cant say when my watch got updated with V21.  It is on this version and the drain is worse than the last time whereas they rolled out a display version.   But it has gotten so bad my last day percentage was 85%, with an hour activity.  Charged it last night and has been off the charger for hour now and currently has dropped 5.9%.  So ~5% in an hour is terriable!   Here I plan to start increasing my training by a good bit and now my watch isn't going to hold up to record my data. 

  • So playing around with things I seemed to figured out that updating the watch faces after firmware update makes it a bit better.  Its somewhat back to normal.   I thought these things were set for auto update but obviously not as I had also data fields updates etc. to do also. 

    • Updating apps after upgrade is a must next to reset ofthe watch as I wrote above. Mine consumption was already stable and after last charge it started all of a sudden to be 3% per hour, only reset helped.
