Huge battery drain

Since the 26.00 update i have a huge battery drain. My Watch consume 10%/h without any activities. It’s totally useless. 
i have tried soft and hard reset without sucess. 
What can i do to resolve this ? Is there any possibilities to go back on thé previous firmware ? Because thé Watch worked fine before, si it’s not an hardware problem…

my Fénix 6 (non pro) is 3 years old so not under waranty and i don’t want to buy a new one. 
Thanks for your response.

  • try hard reset, as in you'll have to set up the watch from scratch; avoid any 3rd party faces, and disable:
    1. pulse ox  (or the oxigen meter)

    2. bluetooth OFF, and if you're using an iphone, then make sure that garmin connect and connect IQ do not have the setting to run in background. I read somewhere that when BT is on and those app running - the battery drains very fast.

    3. wifi off

    and use a garmin native face, something that will show only time, date.

    All that to see if it'll make a change in the behavior at least. Hope it'll help.

  • Following. I have the same issue with my Fenix 6 even after the resets. Turning off all these features might work, but it leaves the watch with limited function and makes it useless. Battery doesn't last 24 hours even without engaging activities and won't get through a single round of golf. 

  • I have pulse ox off, but turning bluetooth off and not running GC in the background means giving up on a whole lot of functionality. My Fenix is my daily watch and I find notifications essential. Having to manually upload workouts again would also be a large step back. I really like the custom watch face I have used for years, and don't want to go back to a stock one. I know this may cost some battery, but until recently even with GC in the background, bluetooth on, and a custom watch face, I had adequate battery life. Now it is terrible. So something changed on Garmin's side, and having to give up functionality to get back reasonable battery life would be really bad.

  • I have try many hard reset, have more Widget or watch face, have disconnect the phone... But still the same drain. My watch is become useless... It was also my daily watch... But during the last month, my watch worked perfectly and i just charge it once a week. So sure it's not an hardware problem. I really wanted a response from garmin...
