A:AnswerI cannot imagine that the speaker would not work with your phone. It synced very quickly and easily to my iPhone and iPod. When I left the room, thus breaking the connection and subsequently returned, the speaker took up where it left off; I did not have to re-sync.
A:AnswerIt's a lipo type battery. I believe it has smart discharge to save batterys from holding charge and damaging cells. How long that takes I don't know yet, I'll be using it all the time from charging some of my quadcopters to using it for wifi repeater for my quadcopters and ofcourse my phone. Honestly if you're looking for a better power bank then buy the $20 one. Huge power bank in power storage but small in dimensions.
