After 18.10 update my battery went down from 53% to 10% in only one night...!

Even in Battery Save mode, without any Bluetooth connection, no Pulse Ox, no Sleeping Monitor and without Hear Rate monitor.
What happened to my Instinct Solar?
I hope GARMIN will fix this serious problem as soon as possible.
It's incredible that to fix a problem (altimeter) can creates another one...!
Can my Instinct Solar fully function correctly as it did several updates ago?

    After every upgrade there's battery drain (SIC!). To fix the problem you must restore the watch into settings options.

    doesn't help!

    fully discharge and fully charged overnight

    hard reset (CTRL button long press)

    factory reset

    updates/downgrades

    still down from 100%(24d) to 0 during 1-2 days.

    Mine stayed 100% overnight...shows the % if I connect to a charge cable otherwise says 27d

    I have done a SOFT RESET (by pussing CTRL button till it's off) and then i turned on again. It seems quite OK for the moment. I will fully charge it and see what it happens. In the other hand, one alarm has sound and I don't know why (there was no alarm set.)...?  It looks like this last update makes the Garmin get completely crazy. Let's see in the oncoming days... Thank you.

    I found that turning the compass OFF in settings gave me huge (back to normal?!) battery life again. I re-enabled the compass, but set to AUTO instead of on and now the battery life seems to work properly again. Could be worth a shot?

    With the SOFT RESET I did I resolved my problem but thank you very much for your idea. I'll keep it in mind.

    Did 1 night 28mi loop this weekend in Adirondack NY using Solar in hike/navigate function. After, 17.8 miles, 7000 ft elevation gain, the watch just frozen (fully charged) ... cant do anything ! Temp was about 45F. Wow...maybe elevation gain killed it, lol

    I have the exact same problem. I've done restarts, soft resets, factory resets, disabled compass, disabled pulse ox, disabled, reset and didn't pair to my phone, disabled activity tracking, put is battery saver mode. The watch is lasting longer after all of this, but still less than a full day on a full charge.

    I wish I could roll back the firmware, but I can't find the older version.

    It turns out that each public release candidate comes with the rollback firmware to the last official release. I was able to download the 18.10 release candidate and use the rollback installer. I've now gone back to 17.50, and will report back my findings. If anyone else is looking for the 17.50 installer it's included in the download here:

    I rolled back to 17.50 and the battery drain issue went away. The problem was that my HR monitor and Pulse OX stopped working. I then upgraded back to 18.10 and the battery drain issue was back, but my sensors were still not working. They just released 18.41 beta today. I'm going to install that now, and see if it resolved any of these issues.
