battery goes to 0% after full shutdown

This is the 2nd time its happend to me after the new 5.0 update.

I go for a ride shut down the garmin completely (yes there is no more symbols on the screen) next day when i want to go for a ride the garmin wont start. 

if i plug it in it doesnt boot but shows battery recovery and after 20 sec it boots with 1% :/

this is realy annoying when you are ready to leave.

didn't have this problem on the previous s/w
