Hi, welcome to the Fitbit Community forums, @Ugie.
Thank you for sharing all this information about the trouble you've been having with your Inspire HR.
The battery can last up to 5 days; because battery life is affected by use and other settings, actual results may vary, but the battery shouldn't be draining only after one or two days.
