This is unbelievably annoying. I power off my Passport, and its turns off completely as expected. A few minutes later, I plug it in to my USB charger and the phone turns back on and I did NOT press the power button. Then I have to wait for it to boot to turn it off again. It still has lots of battery left when I plug it in to charge, its not like its dead and then booting up to a last state. Why is this happening???
