Sena 10U battery status

I do own the Sena 10U for Schuberth C3.
What I find very annoying is that you don't get a notification about the battery status through the intercom. I know that you can check by the blinking of the LED's but that is not practical, because you usually turn the Sena on when you already wear the helmet. And for sure it's not convenient.
I do get a verbal notification when the battery is low, but that is like 3 min before the Sena shut's down. Not useful.
I recommend you implement a function with the next firmware upgrade automatically notifying battery status each time when you turn off the headset.
Thx.
