Paranoid

i am one who's phone will never run out of battery. because i tend to have a phobia that although my phone left like 30 percent of battery, that it will die the next day. and being paranoid, i would switch on my media or play games to let the battery go to like 10% and charge it again. and i do it lots of times. maybe cause 100% of battery gives me the sign that my phone will not die soon! since it 'decides' how am i going to go home. do you do that? or maybe it's just me.
