Battery Drain 955 solar

Well, I have just finished a run in the morning today. So far no excessive drain noticed.

So, just to give you an update… I think, I do not know for sure, that it could be caused by garmin connect …. I’ve had bluetooth ( on phone) turned off for 24 hours and watch seems to have gone back to normal battery life… will keep observing… shouldn’t have to turn that off but it’s something I have noticed…

Thank you for the advice. However I have usually Bluetooth turned off on my phone as I had my old watch in 20.xx, however it didn’t resolve the drain for me. I still believe it’s a software issue.

Sure it might be, but there have to be additional circumstances.

As I wrote above, with 20.xx initially I also had more power consumption. But now it is back to normal.

Charged it to 100% two days ago and rebooted. Now I am at 84% after 48 hours, including 1,5 hours GPS activities.

Garmin Share is off and the IQ App on the watch deleted, Bluetooth is active during daytime (and smartphone with GC App always near), flight mode during night.
Sleeptracking and Move IQ I use, but SPO2 is switched off.

I have had the same settings. I have even tried to enable flight mode for all the time (expect GPS activities). Unfortunately that was neither helpful to me. 

I drained it almost completely before updating to 20.32. (The battery drained very quickly with 20.31.) I put it on a charger and charged it to 100%. I installed the new software 20.32. I did a soft reset and put it on overnight with normal settings (SPO2 off). It didn't drain anything in the morning. So far, 12 hours have passed since charging and it has only drained 2%. This is promising for me, but I need to test it longer.

It's always a good idea to switch the watch off and on (the standard menu option is cleaner than using the "hold down the light button" forced reboot) after receiving a software update.

You'll hear the "hold down the light button for 30 seconds" method called a soft reset. It's not a reset. It's a hardware watchdog power off. It's an emergency measure and doesn't close processes down cleanly or write stuff in RAM back to the internal flash storage. In PC terms it's like flipping the power supply off and on. 99.9% of the time everything will be fine (with a loss of a few hours of HR and stress data), but there will be the very rare occasion the watch was in the process of saving data, and it corrupts something important.

Pretty sure that kinda worked for me.

I updated from 19.18 to 20.29; at the beginning  the battery drain went up (from 2% to 7% at night, while I was sleeping). After turn off Garmin Share and Jet Lag Assistent, my 955 Solar is draining 2% battery at night again.

I realize that after update, the solar charge works better than before,watching even as the level of the battery has increased (1% more) by carrying the clock on my wrist without doing any physical activity; something that I never have seen before.
