No battery percentage means going to sleep and your fitbit (Luxe) stops gathering information. An email after I'm sleeping is really to late for me to do anything to correct the issue. This is frustrating beyond belief. It's not bad enough I've had no heartbeat or no respiration lately but this latest update is doing nothing to help me keep on track. My steps aren't being counted correctly, just stops then starts. It makes me wonder if there's a better smart watch out there.
