Low battery notification
AS A: user I WANT TO: be alerted by the bracelet when the battery is low.
AS A: user I WANT TO: not be disturbed by the low battery warning during do not
disturb mode.
1. A1ll is ON. (Charger is not connected)
2. When battery level is beneath a certain level A1ll will vibrate five
times combined with a red LED. There will also be a popup from AHA
that notifies the user of A1ll running out of battery. The red LED should
continue to blink every 6 second the same way as a notification would
do.
TBD if there should be one or many low battery warnings and at which
percentage level depending on battery consuming mode and scheduled
Do Not Disturb.
