Please explain Luxe battery Off-Hours

[BeHea1thy]

My Luxe is starting to show signs of age at 2.5 years. When removing from the charger at 100%, I put it on to sleep and within 30 minutes the charge is reduced to 80% 8-9 hours sleep time results in 64% charge. 

I noticed in the settings there are Off-Hours, between 10PM and 6 AM. I am confused because the instructions say, turn on to save battery. Yet, that is opposite what I would expect. 

I currently turn on Sleep Mode by swiping down, and selecting it. Should I be going into a sub-setting menu and turning it on there? 

I routinely restart every morning when I turn off Sleep Mode. This has drastically improved performance and syncing issues. Then I put it on the charger. 

Finally, is the Luxe being phased out and slated to be discontinued? It seems that this device is trailing behind the others, perhaps due to it's popularity, limited functions and age.  

Thanks for your time.

@BeHea1thy   Those off hours are part of the Sleep Mode Schedule, so your Fitbit will go in and out of sleep mode on a schedule.  You are doing this manually.  When you don’t use sleep mode at all, your screen can turn on to its full brightness when you move in your sleep.  All those little activations add up.  This is why sleep mode, automatic or manual, saves battery.

The Luxe is a discontinued model.

Too soon old, too late smart. 

Thank you so much @LZeeW. It takes me quite a while to learn the ins and outs of the tech I need and use. I have set everything I can to save, but the writing is on the wall. An upgrade is necessary. Have a good day!
