This is the Samsung Health App causing the issue .We've been on this firmware for awhile now and no issues... Since they started changing the Health app (which is HORRIBLE compared to the original) this drain issue reared its head ..
I hope they're following this thread because whomever redesigned the Health App should be demoted... The text is horribly small. The forced advertisements at the top with no way to opt out is Bologna. The health insite is just SILLY! Seriously does anyone agree with me?
And PS: How about glucose monitoring SAMSUNG if you want to make something groundbreaking!
Hi i had the same issue
It does seem to be the health app
what i have done untill there is a fix, open the galaxy wearable app on your phone, under settings select notifications, then select manage notifications and switch off samsung health.
I charged my watch to 100% about 2 hours ago and it is still on 100%, hopefully will help until there is a fix for the health app.
