I'm on iOS 6 I've turned off radios an almost all notification and I did do a complete restore and set up as new iphone I've looked all over the web to find no fix when I use my iphone the battery percentage goes down every minute no joke every minute but when it's in sleep mode it lasts normally it seems any ideas is my battery bad ? Is there an app that tests the battery or anything thanks for your help in advance 
O and I don't have a warranty I've had my iphone for about 2 years now
