My aunt just got a new bluetooth and she was wondering how long you are supposed to charge it for? It doesn't tell us in the manual so she just charged it for 2 hours and the little light was still green. (green means you only have 10 minutes of battery life left). Please help us! Thank you! 
ok hold on. The manual said to charge it for 2 hours but it was still green. She thinks that its not enough so what do you guys think?
