I need help
How will I watch it for eight hours and my phone will die in only 1 hour? 
Oh and btw
Is it normal if I hear Weio weio weio after I heard just some of alpha waves?
Instead of dealing with battery issues, you can always download my tracks, play them directly from your phone, then leave the screen off all night: http://bit.ly/bestbinauraldownload
