I bought a bluetooth speaker on Amazon, which is the first bluetooth speaker I have ever bought. I've always just been a headphones kind of girl, so I'm sorry if this question is silly, but the instructions and the seller are no help. So...I paired the speaker with my iPhone and it's not working, but something came up in my status bar next to the battery that I had never seen before when I paired it. (See photo) I assume this probably means the speaker's battery is low, am I right? However I tried to charge it a while and it seemed to stay the same...in general, is it better to have the device turned on or off when charging and not in use? Again, sorry for the silly question, and sorry the screenshot is so big. Lol.
