hello and thanks folks for this great piece of hardware 
but this type of battery monitoring is a little annoying to me (I already have displaying percentage enabled, but i dont look at it constantly…), as it does not notify me before the phone is about to shutdown when battery is exhausted so i can plug in in time. also i saw, other common (open source) apps for battery monitoring are not supported yet…any recommendations? thanks in advance
Hmmm… Your phone should give you a notification when the battery drops to 15%.
i think i found out why i didn’t got warned (again?) as i setup energy save mode starting at 75% so the phone already is/was in energy save mode (as i am keen to use phone as long as possible without recharging it, i do want it to save energy all the time…). i think the warning (which is a suggestion to use energy save mode) is then simply obsolete and wont appear…
another additional warning (beside energy save mode) would be good, so some gets reminded that the phone is going to power down soon. 
thanks, regards
