A:AnswerThere is no battery, or charging. You have to have them plugged in when using them. I do not know why they are called Portable, kinda misleading.
A:AnswerIf it is bluetooth capable, not sure about any other ways. I hook it up to my desktop which has bluetooth and use it versus my desktop speakers, incredible sound.
A:AnswerI have an S3 and it connects to it perfectly fine. You are right the connection does not work as it is made for an IPhone or Ipod. Be sure to hit your connect button on the system and then allow the bluetooth on your phone to find it. I have had to disconnect my phone once or twice and connect it again, but it has never failed to connect correctly. I listen to music from You Tube videos as well as from Spotify on my phone while bluetoothed to the Sony!
A:AnswerI would re read the instructions make sure to switch on the correct function. I don't have an apple product can't tell u about that. But I use usb cord and a simple mp3 player. I have no problem
