I downloaded White Noise in January to use on the iPhone4S. It worked great, esp the air condition and airplane sounds. Since the upgrade in software to 5.1.1, the battery life has gone down a lot esp. when I run White Noise. As a way of troubleshooting the problem, I worked with Apple to find the problem. They tried several different things. After taking all of their suggestions, I removed White Noise from the phone. After that, I was able to recover 1 hour of battery charge from each full charge.
Am I the only one having this problem, or is there a fix available? I really like using the app esp. when I travel. Thanks, Kenny
