Just a background quickly, iPhone 5, iOS 6.1, Bitesms 7.5. I've always been a fan of bitesms until recently I've been experiencing battery issues. After conducting a variety of tests, I realized that when Bitesms is running in the background, even when my screen is off, my usage time is going up. But when I kill the the app, the usage time stops when screen is off. So, obviously bitesms is running something in the background that is affecting my battery. Anyone experiencing this? Any explanation? Thanks in advance guys.
