Fenix 8 Amoled 47mm - Battery Drain

Question

Hi, 
 My Fenix ​​discharges very quickly. 20% per day without GPS workouts and without AOD. That's relatively high compared to my Epix 47mm. Does anyone else have the same problem? I hope that this will be fixed with the next firmware update.

Our engineers are still investigating battery drain concerns associated with the Fenix 8. They would like to point out many things that are expected to increase battery drain beyond the estimated days remaining. This could include any of the following: 
 
 GPS (in particular All satellites, or Multiband settings will use more battery life) 
 Voice Features 
 Phone assistant 
 Backlight (It is recommended to reduce the brightness. Gestures will turn this on more frequently) 
 Notifications 
 Alerts 
 Vibrations 
 Animations (as with yoga or breathing activities for example) 
 Connect IQ apps or watch faces (many of these have been found to drain the battery more quickly) 
 Pulse OX either All day or During Sleep 
 Paired sensors 
 Music 
 Paired Bluetooth headset 
 Watch faces with second hands 
 
 So when you are measuring your battery drain, be sure to take these items into account. If you are seeing a rapid drain, please feel free to reach out to me via Private message so I can collect some details.

Update September 25, 2024: 
 Our engineers have discovered an issue that was causing incident detection to remain after, after being used in an activity. This was causing a significant increase in the battery drain. The BETA software version 11.81 has been released to correct this. So if you are experiencing this issue, you can install this update.

Dear all, 
 I owe Garmin an apology. I have been writing a lot on the forum about the battery drain and used pretty strong words against Garmin. So my problem has been that the drain happens when I use the Coros HR armstrap. If I don't use it the watch is perfect. So.... on Saturday I ran with some friend in my backyard. I told the about my problems. They asked if I have updated my HR strap from Coros. I did not know that I could do that. So..... I downloaded the Coros app on my phone, updated the Coros HR armstrap and VOLA everything is perfect. Sa again sorry Garmin. Hope this also can be helpful to others.

The watch started to burning fast after me updating it. Resetting the appliance appeared to help me to solve the issue. Additionally turned off wi-fi, garmin share and emergency reactions.

it just came to my attention that when do not disturb is enable the battery drain is higher (2% during sleep when all connection disabled)
