Ever since the new update to track REM sleep, my Charge is entirely inaccurate with my sleep calculations, to the point that this device is now worthless as a sleep tracker. The reason I bought a Charge 2 was to track my sleep, so this is not acceptable for my needs. It used to show me as being in "light sleep" when I was awake but not up walking around frequently, and "deep sleep" for anything else (including light sleep), but would at least calculate only the deep sleep hours as my total sleep. It's now showing me as being in "light sleep" or "REM sleep" when I'm awake but not up walking around, but it's showing those as my total sleep. For example, if I am sitting up in bed reading a book for 3 hours, it's now logging that toward my total sleep. Is there a way to set the app back to the pre-REM tracking version? Otherwise, how do I return the device after owning it several months?
