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?

  • The battery issue is still happening in 18.41, and the HR monitor and Pulse OX still do not work. My next step is to reach out to support.

  • Hi, they’ve released a 18.41 beta update that’s solved the issue for me regarding battery drain etc

  • I have the same issue. Mine will drain from 100% to zero and shut itself off in less than 24 hrs without me even touching it. I contacted customer support and they tried to tell me it was a hardware issue even though I had no issues prior to the update and I've found numerous forums about people experiencing battery drains on their devices (Instinct and other Garmin devices) after a software update. They said the only solution would be to exchange it for a refurbished one per the warranty. I'm not taking any chances on a refurbished device.
