Would be nice if

Would be nice when turning off it said turning off or something. If you hold the button to long it turns back on.
Would be nice when charging, you didn’t have to hit the power button for it to say charging.
Would be nice to have a separate charger or a plug on the battery itself.
Would be nice if the battery level on the app was more accurate, after charging, sometimes it will show low battery then full charge.

Perhaps I missed it in the directions but I can’t seem to find where the power button is located? I even tried holding some of them down. Maybe I held it down too long like you mentioned?!
