I received my Garmin watch on March 4th.
I registered it and updated to the latest software V8.12
I downloaded some analog watch faces
I left the factory default settings on and everything seemed to be working fine
On March14th I recharged the watch while I was taking a shower. It was at 100%
Later in the evening of March 14th, I had a warning to put the watch in the "Battery Saver" mode because the watch had depleted to 10% remaining, after only 10 hours!
I recharged it to 100% before I went to bed. In the morning of March 15th, the battery was down to 59%.
I talked to Garmin customer support and they said they alerted engineering about the issue.
I recharged the watch again on March16th and it started to behave again.
This morning, March 20th, 4 days after my last recharge) my watch was still at 73%!
I misplaced my phone in the morning of March 20th, so I used my watch to locate my phone. I noticed that the Bluetooth phone setting was off on my Venu 2 Plus. I assumed it was always on. I touched on the Bluetooth icon to ring my phone. I found my phone and went on with my activities. I did not receive or make any phone calls.
Later on March 20th I looked at my battery status and it went down to 66% at 12;45 PM........then 62% at 1:45 PM......then 54% at 3:36 PM......and then 49% at 4:56 pm. At 4:56 PM I tapped the watch and turned OFF the phone bluetooth icon on the watch. It is now 7:06 PM and the battery status still shows 49%. The battery drain must be related to the bluetooth circuitry.
Bluetooth should not cause this kind of drain when in "standby" (no conversations taking place) I have earbuds that get 240 hours (10 days) in bluetooth standby.
I will be calling Garmin again to share these observations.
